fd9f67c1 4 - original version; created by h2xs 1.18
02d1d628
AMH
5
60.02 Mon May 10 20:20:20 1999
7 - Added PPM writer, and a new return type to
fd9f67c1
TC
8 be used to return undef() from a function returning
9 (int)0.

AMH
10
110.03 Thu May 20 23:23:23 1999
12 - Added Pseudo image handling thingies, now
fd9f67c1 13 you can use your own get and put pixel routines.
02d1d628
AMH
14
150.04 Mon May 24 22:14:55 1999
16 - Rewrote parts of jpeg support.
17
180.05 Tue May 25 23:40:01 1999
fd9f67c1
TC
19 - Added png support with libpng
20 fixed error reporting and return types from
21 some format routines.
02d1d628
AMH
22
230.06 Wed May 26 19:05:39 1999
24 - Fixed Data::Dumper being used when it shouldn't have
fd9f67c1
TC
25 added feature checking to see at run time if
26 certain formats are avaliable.
27 removed some ancient C++ style comments that hadn't
28 been properly removed, some out of bounds errors in ppm.c
29 fixed tests so missing features are skipped.

AMH
30
310.07 Thu May 27 03:15:00 1999
32 - Fixed the typemap for i_img and i_color so that you can pass
fd9f67c1
TC
33 a null pointer to them without getting a warning when warnings
34 are enabled. Maybe this is counter perl but it greatly increases
35 the usability of the functions.
02d1d628
AMH
36
370.08 Fri May 28 14:13:21 1999
38 - Added support for gif via, giflib or libungif.
fd9f67c1
TC
39 gif is so ridden with patent issues but the user
40 can decide which library to use since they have the same
41 include files and calling interface.
02d1d628
AMH
42
430.09 Mon May 31 17:52:32 1999
44 - Added image scaling per axis - faster than doing both
fd9f67c1
TC
45 axes at the same time. The current method uses lancoz
46 kernel and filtering. But more types should be added -
47 including: nearest neighbor, linear, and bicubic.
02d1d628
AMH
48
490.10 Mon Jun 7 03:25:54 1999
50 - Added T1 postscript font handling. It's very primitive
fd9f67c1
TC
51 at the moment but creative people can do nice stuff
52 with it. Currently it is not possible to have it
53 generate an image of the correct size for a given string
54 but that is on the way.
02d1d628
AMH
55
560.11 Mon Jun 7 14:43:35 1999
57 - Added T1 features for direct to image rendering in
fd9f67c1
TC
58 a single color. fixed some debug messages going to
59 stderr instead of a log file.
02d1d628
AMH
60
610.12 Tue Jun 8 02:58:43 1999
62 - Fixed bugs in jpeg.c when loading images. Also specified
fd9f67c1
TC
63 prototype behaviour to on in the Imager.xs file. The
64 Makefile.PL step doesn't complain anymore so that is
65 hopefully fixed.
02d1d628
AMH
66
670.13 Wed Jun 9 06:55:58 1999
68 - Fixed Imager.xs for init_log call. Minor fixes here
fd9f67c1 69 and there.
02d1d628
AMH
70
710.14 Thu Jun 10 14:11:22 1999
72 - Rewrote most of the logging stuff so that it is now
fd9f67c1
TC
73 possible to remove all logging from the XS part of the
74 module. Also some primitive check of memory usage was
75 added. Claes Jacobsson sent in some filters, inverter,
76 contrast and a noise filter.
02d1d628
AMH
77
780.15 Mon Jun 14 08:13:29 1999
fd9f67c1
TC
79 - Wrote minor enhancement on the calling syntax list.
80 Started on the object interface - added better support
81 for quering avaliable filetypes. Fixed memory leaks in
82 most loaders. New filters from Claes in this version
83 are bumpmap, postlevels and mosaic.
84
850.16 Wed Jun 16 20:54:33 1999
86 - Added fixes to the BEGIN and END parts, added writer
87 function for the OO interface. Also added basic IPTC
88 reading support for jpegs. Also a few filters have been
89 added to the OO interface.
90
910.17 Thu Jun 24 11:09:15 1999
92 - Added dynamic loading stuff - It's still missing a nice
93 global symbol table. This will be fixed in next release.
94 also calling the plugins is not all to easy at the moment.
95
96
970.18 Mon Jun 28 12:31:33 1999
98 - Added global symbol table - plugins now need a symbol
99 table pointer in them. When the module is loaded it is
100 set to point at the global symbol table. Also some barebones
101 Makefile.PL has been made in the dynfilt directory - it works
102 on my system - I hope it does on yours.
103
104
1050.19 Fri Jul 1 15:00:03 1999
106 - Added a way new scaling method for creating easy previews.
107 It only uses nearest neighbor, so it's doesn't look very nice
108 but it may be better for applications like remote sensing.
109
1100.20 Mon Jul 5 10:15:37 1999
111 - Added and rewrote documentation.
112
1130.21 Mon Jul 6 19:15:37 1999
114 - Fixed a bug in the scaling routine - it wasn't
115 handling 0< cases.
116
1170.22 Sat Oct 9 07:04:14 1999
118 - Added a new method to write gif images - now
119 it is possible to have a part of a palette fixed.
120 this is very usefull if one needs to make sure that
121 some color like white is in the pallete. This method
122 also allows some ditherding and gives better colormap
123 than the mediancut from the gif libraries. It does
124 need much more cpu power though. Hopefully later versions
125 will be faster.
126
1270.23 **************** Internal release only
128 - Fixed the %instances bug - caused ALL memory to be leaked.
129 Added real noise function - need feedback on how it should
130 be used. Also box(), and polyline are now in place. Polygon
131 is missing but antialiased line drawing with integer endpoints are
02d1d628 132 done but should be replaced with a version that can have
fd9f67c1 133 floating point endvalues. Two noise filters addded.
02d1d628 134
fd9f67c1
TC
1350.24 **************** Internal release only
136 - Converted i_color into an object from a reference, so now it's
137 giving an object instead of a void ptr or an integer or something.
02d1d628 138
fd9f67c1
TC
1390.25 **************** Internal release only
140 - Added basic Truetype functionality - still needs a rewrite
141 to be decent. Currently it's a port of a demo program that
142 uses an awful amount of global variables and there is much IO since
143 no caching of glyphs is done.

AMH
144
1450.26 Tue Nov 23 03:57:00 1999 > Development release <
fd9f67c1
TC
146 - Added transformations so that an image can be wrapped.
147 To achive decent speed a C based stackmachine is included. As a result
148 transformations need to be specified in rpn (postfix) notation. It
149 also can use the Affix::Infix2Postfix class to do the conversion for it.

150
1510.27 Tue Dec 28 03:57:00 1999 > CPAN release <
fd9f67c1
TC
152 - This is a bugfix version mostly, thanks to claes for pointing
153 out the problems - fixed palette saving wasn't working correctly after
154 version 0.24 - rather surprised this didn't crash everything.
155 Also fixed that for t1 fonts the bounding box wasn't being reported
156 unless the font had been used before. This is either a bug in t1lib
157 or a mistake in it's documentation. Another lingering bug since 0.24
158 what that $img->box() wasn't creating it's default color properly.
159 Added i_tt_text() method and more debuging to the truetype routines.
160 truetype testcase fixed and old debug rubish removed.
02d1d628
AMH
161
1620.28 Tue Jan 4 05:25:58 2000 > CPAN release <
fd9f67c1
TC
163 - Only fixes to truetype test and transformation tests.
164 Thanks to schinder of cpan testers for testing and reporting.
02d1d628
AMH
165
1660.29 Tue Jan 4 21:49:57 2000 > CPAN release <
fd9f67c1
TC
167 - fixes to get rid of warnings under pre 5.005,
168 Fixed broken preproccessor directives to work on non gnu
169 compilers. Fixed DSO test on HPUX - both code errors and
170 HPUX creates .sl instead of .so so the tests were failing.
02d1d628
AMH
171
1720.30 Sun Jan 7 05:00:06 2000 > Bunch of Alpha releases <
fd9f67c1 173 - An attempt to automate installation.
02d1d628
AMH
174
1750.31 Sat Jan 15 03:58:29 2000 > Fixes fixes fixes <
fd9f67c1
TC
176 - Fixed a bug pointed out by Leolo where loading gifs
177 skips the first line of the imageload() has been
178 by read() - for now load is an alias for read. It will
179 be removed in the future. Also, fixes dynamic loading on
180 systems that prepend an underscore to symbols. At the present
181 the only system that I know of that needs this is OpenBSD.
182 BUT YOU MUST RECOMPILE ALL OF YOUR OLD MODULES AGAINST THIS BUILD.
183 Added getchannels() method ( How did I manage to delay this
184 untill now ). Some document changes but nothing substantial.
185 Also fixed the png read/write routines to handle all colorspaces
186 and images with alpha information. Also now it's possible to
187 have Imager guess the format of the files to load or save
188 when passing files to read or save from the filename.
189 Also all of the tests except dynamic loading now pass on OS/2.
02d1d628
AMH
190
1910.32 Tue Feb 29 17:26:00 2000 CPAN RELEASE
192 - Added the getcolorcount method. Fixed interlace handling
fd9f67c1
TC
193 on png images. Fixed the missing channel count in crop()
194 method. Rewrote most of t1lib database stuff - created color
195 and font classes. T1 stuff is mostly done - TT things were
196 rewritten too and now include most of what is needed for
197 pixmap caching. Added documentation for fonts. Comments have
198 been added to some of the relevant c-routines. Added a copy()
199 function in Imager.xs and a corresponding method name.
200 Changed the underlying data type for the raw XS images from
201 pointers to objects - this will hopefully catch the most
202 basic errors and keep the segfaulting down. This means that
203 all of the underlying XS calls for readjpeg, readgif, readpng
204 and readraw do not take the first parameter any more.
205 Made fixes to keep it not spewing warning on 5.004 perl.
206
207 **** If you had any code that didn't use the OO interface ****
208 **** It will probably not work any longer ****
209
2100.33 Beta -- No final
211 - Fixed the end message from Imager 0.32. Destroy called
212 on an empty image. Did some work on the polygon method.
213 Some clean up in the Makefile.PL script. Fixed a buffer
214 overrun in the t_transform in Imager.XS. Fixed the
215 error handling in the jpeg loader. It now correctly
216 returns undef if a load on an image fails. It also
217 sends the error messages to the log file. Added errstr()
218 method to the image object. Added a new way to read()
219 objects from scalars. So far this is only implemented for
220 jpeg, png and gif. ppm and raw soon - as always if someone
221 wants to do an overhaul on the ppm stuff feel free. It seems
222 like such a basic format that interfacing with a library is more
223 work than implementing all of the needed routines instead.
02d1d628
AMH
224
2250.34 Beta -- No final
fd9f67c1
TC
226 - Bunch of documentation fixes, backed out ppm code.
227 Put in TonyC's giant transform2 patch. Fixed the patch
228 to make it ansi compliant. Fixed a bunch of bugs in the
229 Freetype code with regard to vertical and horizontal
230 positioning and bounding boxes. Cleaned up a lot of the
231 code so it runs under -Wall. Code that is still in
232 development such as the polygon converter do not compile
233 cleanly. Fixed the non antialiased versions of truetype
234 dump to image routines. Also removed the FIXME for the
235 hardcoding of antialias in the Imager string method.
236 Fixed sign error and a missing cache of the bounding box
237 calculation for the rasterize function. Removed some
238 debugging code I forgot to remove. Added iolayer.h
239 and iolayer.c but they don't do anything for now.
240
2410.35 pre2 -- No time yet
242 - Fixed some compile warnings for various files under -Wall.
243 Added functionality for jpeg reading of seekable files, it's not
244 really working yet. This version is pretty much *not* working.
245 Do not install unless you intend to do a lot of development.
246 Repeat - it doesn't even pass tests (but it compiles). Ok now reading
247 jpegs works from scalars, my guess is that it also works from non
248 seeking sources such as sockets or pipes.
02d1d628
AMH
249
2500.35 pre3 - No time yet
fd9f67c1
TC
251 - Added the *right* patch from Tony which combines
252 the common code from i_readgif and i_readgif_scalar into
253 i_readgif_low. Added tiff reading support through iolayer.
02d1d628
AMH
254
2550.35 pre4 - No time yet
fd9f67c1
TC
256 - Added tiff writing (no options) support through
257 iolayer. Also made some small fixes for the iolayer reading
258 (was always doing two reads when one was needed). Patched the
259 Imager::read() call so that it now uses a mixture of old and new
260 functions.
02d1d628
AMH
261
2620.35 pre5 - No time yet
fd9f67c1
TC
263 - Fixed various gnu'isms in the c code (some bugs in the link list
264 implmentation). Fixed missing #skip codes when gif format is not
265 present in any form. Added fixes for 5.004_04 in the transform2 function.
266 Made sure it compiles cleanly with sun's cc. Switched from a .jpeg
267 for transform2 check to a .ppm file so it runs when jpeg is not
268 present. Added a test for tiff files in t10formats.t.
02d1d628
AMH
269
270
2710.35 pre6 - No time yet
fd9f67c1
TC
272 - Fixes to Makefile.PL. Should find freetype includes on more
273 distributions now. Ran tests on Solaris and Hpux, minor fixes.
274 Compiles with some warnings on with both hpux and solaris' cc.
275 Made some minor changes to the documentation. Fixes to tiff.c log
276 code.
02d1d628
AMH
277
2780.35 pre7 - No time yet
fd9f67c1
TC
279 - Fixes 64 bit bug on freebsd. While libtiff mirrors the effects of
280 lseek it's toff_t is a uint32, while lseek uses off_t which can be a 64
281 bit quantity. Added the IM_LFLAGS environment variable to help
282 people with broken libgifs (that want to link with X).
02d1d628
AMH
283
2840.35 Sun Jan 28 19:42:59 EST 2001
fd9f67c1
TC
285 - More makefile fixes, fixed a few signedness warnings.
286 Checked to see if it compiled cleanly on Solaris and HPUX.
287 Fixed a 5.004_04 warning and added more ENV flags for makefile.
288
2890.36 Mon Jan 29 09:36:11 EST 2001
290 - String as 0 or "" caused an error in $img->string(). Fixed a
291 documentation error invoving string() method syntax. Merged a patch
292 for non antialised truetype fonts. Fixed an error in the Makefile.PL
293 which caused a makefile to be generated that bombed with sgi's make.
294
2950.37 Mon Tue 30 09:36:11 EST 2001
296 - Several documentation fixes. Pod documentation for almost every
297 function in image.c. Added sys/types.h include in iolayer which was
298 causing problems on various linux systems.
299
3000.38 pre1 - No time yet
301 - Fixed a braindamaged fix on the Makefile.PL file. Moved the
302 code for Imager::Color into lib/Imager/Color.pm. Wrote some pod
303 about how it works. Made the names of Imager::Color XS routines
304 all begin with ICL_ and used the prefix rules of XS to get nice names
305 in perl. Found a bug (not fixed) in how XS handles
306 returning an object to an object it had as a parameter (double
307 free).
308
3090.38 pre2 - No time yet
310 - Fixes lots of for documentation, patch for freetype bounding
311 box handling. Split put code for Imager::Font into Font.pm and added
312 more documentation for Font.pm. Added string local ascender and
313 descender for tt fonts. Note that this needs to be added to t1 fonts
314 before 0.38 final.
315
3160.38 pre3 - No time yet
317 - Fixed an in consistency in the bounding box functions for t1
318 fonts. Now both versions get the 6 argument bounding_box method
319 described in Imager::Font. Started converting the comments in
320 font.c so that they are viewable by doco.perl. Added two examples
321 of filters. Need to make them more usefull and then add more
322 notes than are in compile.txt.
323
324
3250.38 pre4 - No time yet
326 - Completed adding pod comments to font.c, tiff.c and iolayer.c.
327 Those along with image.c should now have every single function
328 described in pod format.
329
3300.38 pre5 - No time yet
331 - Replaced ppm.c with pnm.c which adds support for pbm/pgm/ppm
332 files ascii and binary formats. Added patches for the gif routines.
333 Patched some of the color quantizing routines (Leolo and TonyC).
334 There is one bomb and one warning in this test, and frankly I don't
335 see why they are suddenly there.
336
3370.38 pre6 - No time yet
338 - Patch from Tony that fixes infix when Parse::RecDescent is present.
339 Checked some cases where malloc/free were used instead of mymalloc/myfree.
340 Added bufchain iolayer code. You can now write to a chain of buffers and
341 later slurp it all into a single perl scalar. Found some oddity of t/t10
342 test not giving the right return value when malloc debugging was enabled.
343 Fixed some of the logging code and the malloc debugging options. Added
344 more tests for tiffs.
345
3460.38 pre7 - No time yet
347 - Added i_gradgen code and put it into the filters hash. Think a
348 seperate pod for filters would be a good idea. Also removed some of the
349 debugging code from the iolayer. Added pod comments to filters.c and
350 looked over the code.
351
3520.38 pre8 - No time yet
353 - limited Win32 support, Imager installs and builds using VC++,
354 but there's no image/font format support yet.
02d1d628
AMH
355
3560.38 pre9 - No time yet
fd9f67c1
TC
357 - Added lots of color quantization code from Tony with benchmarks.
358 Also fixes ugly stack overrun in old version. Added fixes for the lmfixed
359 problem. Four of them, let's see which is fastest. This version adds
360 some voronoi partitioning - it's dog slow but it's a reference implementation
361 to check if faster algorithms are doing the right thing [tm]. Added a check
362 for giflib 3.
363 - Win32 support for libpng
364 - fixed set_internal creating 2 refs to one object
365 - Win32 support for jpeg
366 - Win32 support for tiff
367 - base level error reporting code added, I still need to modify
6829f5f6 368 older code to use it
930c963d 369 - fix translate=>'giflib' handling of single-colour images.
fd9f67c1
TC
370 Previously a single colour image would cause an error in
371 MakeMapObject().
930c963d 372 - fix t/t10formats.t tests against giflib3
0e03521f
TC
373 - added test for transparent gifs
374 - minor doc fixes for transparent gifs
375 - make it less error-prone to write transparent gifs
fd9f67c1 376 - documented the options for reading raw images
6829f5f6
AMH
377 - Changes switched to use spaces for formatting
378 - switch gif.c to new error reporting with related changes to
379 Imager.xs, Imager.pm
fd9f67c1
TC
380 - each of the image formats now have their own test file,
381 extracted from t10formats.t, usually with som extra tests
df917a00
AMH
382 - Added flip() and docs to Imager.pm and i_flipxy to image.c.
383 Added testcases too.
6829f5f6
AMH
384 - Fixed an overflow bug in png.c
385 - added the colors parameter to Imager::read() which receives
386 the arrayref of colours that i_readgif(_scalar) returns
387 - fixed a problem in makemap_addi in quant.c where only the first
388 image was compared against the palette when the palette was being
389 refined. I screwed up on this originally (TC). This is the other
390 half of a fix for Leolo's lmfixed problem <sigh>.
391 - makemap_addi() now only puts colours into the palette that it
392 found while optimizing the palette (so we don't get 256 colour
393 palettes for 2 colour images :)
394 - initial implementation of a row-based interface to low-level
395 images (for performance)
396 - changed Imager::read() for GIF so that the arrayref pointed to
397 by the ref supplied in colors contains Imager::Color objects
398 instead of more arrayrefs, keep this interface stable until we
399 can make an informed choice about i_readgif()
400 - incorporated Micksa's faxable tiff support, treating as a type
401 of tiff rather than a separate format
402 - t/t70newgif.t now checks for gif support
403 - added the convert() method
404 - Added support for transparent to alpha conversion during loading
ae448e5a 405 of png files. Note that libpng 1.0.1 is broken in handling this,
7828ca98
AMH
406 we know that 1.0.5 works.
407 - support for writing PGM (portable gray map) files
408 - Fix for i_gifread_low() for images with only a local and no global
409 colormap and an abort if no colormap is present (which is legal
410 in gif).
43a881d3 411 - several fixes to i_readgif_low()
299a3866 412 - Fixed crop() method so that it is consistent with documentation.
de2b8bae 413 - make clean now removes the testout directory
4c2d6970
TC
414 - added tests for the OO interface for tiff, added an option to
415 choose the resolution for fax tiffs, removed some unused code,
416 fixed minor problems with Imager::write() handling of image types

faa9b3e7
TC
422 - writing faxable tiff now allows 2 and 4 channel images
423 - virtual image interface - 8-bit/sample images
424 - paletted images
425 - 16-bit/sample images
426 - masked images
427 - writing non-8bit images to raw
428 - writing '' '' to tiff
429 - i_convert support for high-bit images and paletted images
430 - i_copy for high-bit and paletted images
431 - tests for rubthru
432 - rubthru can now rub a 2 channel image over a 1 or 3 channel
433 image
434 - rubthru for high-bit images
435 - i_readgif_multi functions, which return all the frames from a
436 GIF file, along with a bunch of meta-information as tag
437 - OO interface to tags
438 - OO interface read_multi() to read multi-image files (just GIF
439 so far)

446 where the last character overlaps the advance width (eg.
447 italic fonts)
448 - added rotation by exact amounts in degrees or radians,
449 implemented using the matrix idea from Addi. The procedural
450 matrix transformer is exposed, but still needs testing (as XS)
451 and needs an OO interface, hopefully with some helper tools,
452 like the preset interface with ->convert().
453 - MY::postamble() in Makefile.PL included a broken rule
454 (Makefile.PL 1.13.2.5)

465 - retrieve physical resolution to tags when reading from PNG
466 - found an XS bug in the interface to i_tags_add()
467 - fixed handling of writing text to a channel with freetype2
468 (sometimes the edge of a character would damage the edge of the
469 previous character)
470 - some utf8 support for freetype2
471 - some vertical layout support for freetype2
472 - named parameters for specifying colors, with quite a few options.

585 if we don't find a unicode encoding
586 - use the glyph bbox to calculate the glyph bitmaps for rendering
587 with FT1 rather than the global ascender/descender. This helps
588 with fonts that have broken metrics.

be371490
TC
686 - the default tifflib warning handler was crashing on Win32
687 under ActivePerl, when an unrecognized tag was read from the

697 - internal and external bounding box calculations now use
698 the same hint flags as text output for Freetype 2.x
699 - made the i_foo_bbox() interface more expandable by using
700 symbolic constants for the sizes and array offsets
701 - added a / character to the ExistenceTest.foo fonts that
702 overlaps the right side of the character cell, to test the
703 advance width reporting.
704 - added advance width to the i_foo_bbox() interface, and
705 implemented it for FT2, FT1 and Type 1
706 - Imager::Font::bounding_box() now returns an Imager::Font::BBox
707 object in scalar context.
708 - implemented $font->align() text output method, for simple output
709 of aligned text

72e425d5
TC
714 - Debian woody supplied FT2.0.9, which didn't support
715 FT_Has_PS_Names(), so we use the FT_HAS_GLYPH_NAMES() macro
716 instead.
a90b253d

726 - added a correct T_AVREF input mapping to the typemap to
727 simplify parameter lists
3a6bb91b

744 - only call FT_Get_Postscript_Name() on FT 2.0.6 and later
745 - put the IM_LIBPATH and IM_INCPATH values first in the search
746 path so the builder gets their local versions if desired rather
747 than the system versions they might be trying to avoid
748 - document the exp() and log() transform2() functions
749 - document the constants normally set by transform2().
cf7a7d18
TC
750 - refer the user to appropriate documents in the example in

755 void context.
d5a3f460 756 - font.c now only uses the defined T1Lib error codes
e18f39b3
TC
757 - update ppport.h and remove the duplicate definitions from
758 Imager.xs. Had to mangle ppport.h to prevent duplicate global
759 function definitions.
760 - newer versions of tifflib require that all of the function
761 pointers passed to TIFFClientOpen be non-NULL, the mmap() and
762 munmap() pointers were always NULL and the sizeproc was
763 sometimes NULL.
704bb832
TC
764 - there would be a link or load time error on m_init_log() if
765 Imager was built with IM_NOLOG, fixed by renamed init_log()
0ab90434
TC
766 to m_init_log() in log.c (thanks to Takumi Yamani)
767 - moved some variable definitions to the right place
768 - the Win32 font driver bounding box function now returns the
769 right number of values (both thanks to Takumi Yamani)
ea9e6c3f
TC
770 - the Win32 font driver now uses DEFAULT_CHARSET rather than
771 ANSI_CHARSET are the lfCharSet value for the LOGFONT,
772 as suggested by Takumi Yamani.
773 - fontfiles/ExistenceTest.{pfb,ttf} weren't marked as
774 binary in the CVS repository (caused test failures if you
775 built from CVS on Win32)
776 - Makefile.PL should now handle INCLUDE or LIB with spaces in them
777 correctly on Win32.
8b695554
TC
778 - the pnm reader read maxval for ppm/pgm files and then ignored it,
779 it's now validated (0 < maxval < 65536) and used to scale
780 samples. Note that binary ppm/pgm files (P6/P5) with maxval >
781 255 result in an error, since I didn't want to add new features
782 just yet, just get the code that's there working correctly.
783 Thanks to Elthek on rhizo for reporting this and help in
784 tracking it down.
1c00d65b 785 Resolves https://rt.cpan.org/Ticket/Display.html?id=7465
8b695554 786 - added a bunch of tests for reading pnm files.
1501d9b3
TC
787 - previously, if you supplied to_paletted and empty color map
788 and set make_colors to 'none', quant_translate() would segfault.
789 This was because it was making the reasonable assumption that
790 you'd have colors to map to. quant_translate() now checks there
791 is at least one color and return NULL if there isn't.
792 - i_img_to_pal() now does error checking of the value returned by
793 quant_translate().
794 - Imager::to_paletted() now checks for success/failure of
795 i_img_to_pal() correctly and does appropriate error handling.
796 - i_writegif_low() did no error checking on the result of
797 quant_translate(), it now does
798 - we now test that trying to write a GIF image with no palette
799 allowable by the quant options is a failure.
800 - Imager::write() was doing nothing with the result of the call
801 to i_writegif_gen(), in particular it wasn't returning () on
802 failure.
803 - added tests for paletted image handling and the methods
804 specific to those images
805 - the XS for i_setcolors() was missing the OUTPUT clause for
806 RETVAL, and hence wasn't returning failure on failure.
807 - supplying a sufficiently small scaling value could make the
808 scale() method return an image with zero height or width.
1c00d65b
TC
809 Several of the above together resolve
810 https://rt.cpan.org/Ticket/Display.html?id=7467
1501d9b3
TC
811 - the void context warning for scale() now includes the callers
812 filename/line (instead of the default of Imager.pm line 15xx)
813 - Imager->new will now return undef if the dimensions or number of
814 channels specified for an image are out of range. An error
815 message can be retrieved with Imager->errstr.
1c00d65b
TC
816 - added the C<builtin> color specifier and the
817 Imager::Color::Table class which defines those colors.
818 Resolves https://rt.cpan.org/Ticket/Display.html?id=2593

819 - added the equals() method to Imager::Color.
820 Resolves https://rt.cpan.org/Ticket/Display.html?id=2238
0d3b936e
TC
821 - prevent a test warning introduced by the above
822 - the rotate() and matrix_transform() methods now accept a 'back'
823 parameter specifying a background color. This is only used
824 where there is no source data (think of the corners around an
825 image rotated 45 degrees) and it not combined with transparent
826 pixels from the source image.
827 Resolves https://rt.cpan.org/Ticket/Display.html?id=6140
13fc481e
TC
828 - removed a warning generated by the new matrix_transform() test
829 - added a method index to Imager.pm
830 - corrected "flood fill" to "flood_fill" in Imager/Draw.pod
831 - removed compose() method from Imager/Transformations.pod since
832 it isn't implemented yet

833 - the image resulting from a crop is now the same type as the
834 source image (paletted vs direct, bits/sample)
835 Resolves https://rt.cpan.org/Ticket/Display.html?id=7578
676d5bb5
TC
836 - the parameters to crop() weren't handled correctly in most
837 cases other than supplying left,top,right,bottom.
838 - clarified the documentation for crop() providing more detail
839 and more examples
840 - the edges of the cropped area are now cropped against the
841 edges of the source image
842 - cropping to zero width/height is treated as an error (no
843 image is returned and $src->errstr has a message)
844 Resolves https://rt.cpan.org/Ticket/Display.html?id=7581

849- the changes to scale() had some problems with integer vs floating point
850 calculations (only caught in tests under perl 5.8.5 <sigh>)
a4168bea
TC
851- the FT2 glyph_names() method didn't do correct error handling
852 when the string parameter wasn't supplied
853- i_ft2_glyph_name() accepted only an unsigned char as the
854 character code to get the name for, which meant it
855 didn't work for unicode characters \x{100} or above
856- the XS for i_ft2_glyph_name() had a similar problem
857- added NameTest.ttf to be used in checking unicode glyph
858 names
859- added reliable_only optional parameter to the glyph_names()
860 method so you can ignore theresult of FT_Has_PS_Glyph_Names()
a4168bea
TC
861- handle errors given by i_ft2_glyph_name() a bit more
862 correctly
863- the FT1 glyph_names() method didn't do correct error handling
864 when the string parameter wasn't supplied
865- some memory allocated when creating a callback IO object (io_new_cb)
866 wasn't being released (detected with valgrind)
867- the testtools.pl match[nx]() functions escapes the test string on
868 test failure a bit better
17892255
TC
869- the XS code for i_tt_glyph_name() used unsigned char to store a
870 unicode character when it should have used unsigned long.
871- the XS code for i_t1_glyph_name() used unsigned char to store a
872 unicode character when it should have used unsigned long.
873- resolves https://rt.cpan.org/Ticket/Display.html?id=7949
874- the type 1 glyph_names() method didn't do correct error handling

TC
888- creating an image where the size of the allocated image buffer would
889 overflow an integer would cause too small a buffer to be allocated.
890 This could potentially be a security hole.

893- set i_format to png when reading png files and test for it
894- i_yres was being set to the xres when reading a png file
662e3c02
TC
895- added many bad BMP files to test various code paths in bmp.c, and
896 made many minor fixes to bmp.c to make them work:
897 - it was possible for various types of read failures to SEGV, both
898 as NULL pointer dereferences and buffer overflows
899 - some errors, like palettes being too large for the number of bits
900 per pixel, were not being caught
901 - failing to read all of a packed data structure would not cause
902 a read failure
903 - invalid compression types were not always caught
904 - error messages are more consistent (still not always great messages,
905 but one step at a time)
906- added bmp_compression_name, bmp_used_colors, bmp_filesize, bmp_bit_count
907 tags on reading a BMP file
81483e0f
TC
908- added tools/imager to the distribution. This is still very
909 experimental and untested. Patches welcome, if you write tests to go
910 with them.
403946c6
TC
911- the BMP reader now validates the bfOffBits value from the BMP header
912 and skips to that offset before reading image data. Previously this
913 value was read but otherwise ignored.
08ec4969 914- added --palette action to tools/imager

953 FreeBSD keeps freetype1 headers after the freetype2 locations.
954 This ensures that the -I options are generated with freetype2
955 locations first, so that those directories are searched before
956 the freetype1 directories. This prevents problems compiling

f8e9bc07
TC
996- scanning for required include files is now down by directory rather
997 than by file, using -e to check for the existence for a file rather than
998 doing an eq against every filename in the directory.
999- previously we only checked a candidate include directory for freetype.h
1000 to consider it a valid FT1.x include directory. We now check if it
1001 contains fterrors.h too, if it does, then it's from a FT2 installation
1002 and we ignore it.

1012- the right-side bearing used to adjust the final width wasn't being
1013 calculated correctly, this would cause the bounding_box() function for

TC
1050- saving a GIMP gradiant file with Imager::Fountain->save has always been
1051 broken. Fixed it and added tests.
1052- newer versions of GIMP add a line to gradient files before the
1053 segment count giving a descriptive name of the gradient.
1054 Imager::Fountain can now read and write such gradient files. The
1055 interface is a bit indirect, but I'd like to preserve
1056 Imager::Fountain as a blessed array ref for now.
109bec2d

1057- the segments parameter supplied to the fountain filter and the
1058 fountain fill contructor now accepts color names or other
1059 descriptions as other functions do.
35891892
TC
1060- fix a few compiler warnings
1061- document the Imager::Font::BBox advance_width() method
1fbba730
TC
1062- Imager::Font::BBox advance_width() method was falling back to
1063 the wrong value when the font driver's low level function
1064 didn't return the advance width.
8a35bed5
TC
1065- the FT 1.x was comparing versus an uninitialized variable when
1066 checking the end of string when calculating the right side bearing
1067 used to adjust pos_width for glyphs that overlap the right side of the
1068 advance width.
dc35bde9
TC
1069- Imager::Font::BBox objects now have right_bearing() and display_width()
1070 methods. Hopefully this and the advance_width() method fills out
1071 the Imager bounding box interface to a useful state.
8457948a
TC
1072 Implemented for all four font drivers.
1073- Win32 font bounding_box() method now supports the advance width
1074 and right bearing values.

1079- the FT1.x driver now supports the align parameter correctly.
1080 Tests were added to each driver to check correct handling of the align
1081 parameter.
e2d5ca90 1082- the Win32 font driver bounding_box() method now puts accurate values
b692658a 1083 in the ascent and descent values, previously they were set to the
a6d9b737
TC
1084 font ascent/descent rather than the values specific to the string.
1085- supplying align=>0 to the win32 font driver string() function
1086 now aligns in the same way as the other drivers.
f6acebd0
TC
1087- removed the bug reporting email address to prevent spammers stripping
1088 it. The URL is still there and if someone knows how rt.cpan.org works
1089 they can still figure out the email.
63e0dc02
TC
1090- the internal function used to probe file formats if the type
1091 parameter wasn't passed to the read() method would produce
1092 diagnostics on stdout, precluding use in web applications. Silenced
1093 it.
8efd1577

1160 reading a gif file will now read the first image from the file rather
1161 than the a consolidated image. If you want the old behaviour supply
1162 C<< gif_consolidate=>1 >> to the read() method. Older versions of
1163 Imager will accept this parameter and produce the same result.
1164- you can now supply a page parameter to read() to read a given page
1165 from a GIF file.
1166- reading a multi-image GIF was leaking memory (a line buffer per file)
d443d6be 1167- maxcolors now must be at least 1 when creating a paletted image.
5c5abac4 1168- converted t/t022double.t to use Test::More

TC
1251- start of external Imager API access:
1252 - rename headers to avoid conflicts:
1253 - image.h to imager.h
1254 - imagei.h to imageri.h
1255 - datatypes.h to imdatatypes.h
1256 - config.h to imconfig.h (created by Makefile.PL)
1257 - moved all public types defined in imager.h to imdatatypes.h
1258 - supply the PM parameter to WriteMakefile(), to install headers
1259 under Imager/include, and the Imager typemap in Imager/typemap.
1260 We scan the MANIFEST for files to add to PM.
1261 - add "i_" prefix on some functions useful as public at the C level.
1262 - moved the typedefs that support the typemap from Imager.xs to
1263 imperl.h
1264 - set the global callbacks hook in the Imager.xs BOOT section
1265 - API cleanup:
1266 - define i_tags_set(), i_tags_setn() - we might not allow multiple
1267 values for a tag in the future
1268 - i_copy() now returns a new image instead of doing horrible inplace
1269 things to an existing image
1270 - provide actual functions for all of the macros we define in imager.h
1271 so we can put them in the global callbacks structure
1272 - define global functions structure (imexttypes.h)
1273 and initialize it (imext.c)
1274 - add API include header with macros to setup the define and
1275 initialize the local callbacks pointer, and macros to call the API
1276 functions.
1277 - build Imager::APIRef from C sources, including updating the sources
1278 to include documentation for each API function.
1279 - convert dyntest and mandelbrot dynfilts into XS modules (too easy)
1280 - simple Imager::CountColor example
1281- support Inline::C :
1282 - typemap changes to accept Imager or Imager::ImgRaw objects as
1283 image parameters
1284 - define Imager output type for trivial cases of returning an i_img as
1285 a full Imager object
1286 - Inline WITH hook to filter Imager XS types into types Inline::C can
1287 accept, supply appropriate headers and initialization.
1288 - test script t/t82inline.t
1289- try to use XSLoader instead of DynaLoader (but fallback if necessary)
1290- paste() can now paste a subset of the source image.
1291- paste() now has better tests
1292- paste() should now be faster for larger pastes

TC
1340- check $Config{ldflags} and $Config{ccflags} for places to search for
1341 headers and libraries. This deals with the way the fink build of perl

1343- eliminate some of the duplication of -I and -L options in LIBS and INC
1344- Makefile.PL now uses strict.

1376- handle short EXIF user_comment fields correctly, previously Imager
1377 would read (and potentially) write beyond the end of an allocated block,
1378 or through a NULL pointer if the EXIF user_comment field was less
1379 than 8 bytes long.

1381- tifflib 3.8.0 with MDI (Microsoft(tm) TIFF) support produces a
1382 different error when it reads a file with a bad magic number.
1383 Update the test to handle the possible messages.
22845485 1384- some jpeg.c logging calls didn't include parameters enough to match
3631271b 1385 the supplied format string. (detected by valgrind)
