1 Imager release history. Older releases can be found in Changes.old
3 Imager 0.63 - unreleased
6 - the font libraries are now only initialized when needed.
7 http://rt.cpan.org/Ticket/Display.html?id=28825
9 - moved the imtoc.perl code into Imager::Preprocess
11 - paste() and rubthrough() now adapt the source image data to the
12 destination, so you can now safely paste/rubthrough from greyscale
13 images to color images or back, or from alpha channel images to
14 noalpha channels or back.
15 https://rt.cpan.org/Ticket/Display.html?id=30908
17 - rubthrough() now falls back to pasting when the source doesn't have
18 an alpha channel. This effectively treats the source as having a
19 max alpha channel, the right thing to do.
20 http://rt.cpan.org/Ticket/Display.html?id=29944
22 - re-worked most of the area filling code to use a common set of
23 functions when filling.
24 Corrected normal combine mode.
25 Rewrote most of the combine modes to match the way the SVG draft
26 defines them with respect to a translucent source and destination.
27 Added tests for translucent source and destination.
28 Added tests to check 8-bit/sample and double/sample combines work
30 https://rt.cpan.org/Ticket/Display.html?id=29879
34 - Imager::Matrix2d->translate() now only requires one of the x or y
36 http://rt.cpan.org/Ticket/Display.html?id=29937
38 Imager 0.62 - 10 December 2007
41 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
42 to /path under your home directory.
43 http://rt.cpan.org/Ticket/Display.html?id=29484
45 - the old dynaload code used Mach API functions to load dynamic
46 libraries on Mac OS X. These APIs have been deprecated in OS X
47 10.5 and were causing some build problems.
48 So henceforth Imager uses the dlopen() family of functions, and you
49 will need version 10.3 or later of OS X.
51 - added the det() function to the transform2() engine.
52 added the sample quad_to_square.pl
53 Courtesy Richard Fairhurst.
54 http://rt.cpan.org/Ticket/Display.html?id=31244
58 - samples/gifscale.pl sourced the base value for gif_top from
60 Thanks to Eleneldil G. Arilou for pointing this out.
62 - t/t82inline.t no longer loads B at runtime, to work around a bug
63 in some 5.005_0[45] installations.
64 http://rt.cpan.org/Ticket/Display.html?id=30508
66 - work around Module::Depends::Intrusive bug #21229
67 http://rt.cpan.org/Ticket/Display.html?id=30520
69 - the hardinvert filter no-longer inverts the alpha channel.
70 http://rt.cpan.org/Ticket/Display.html?id=30002
72 - the hardinvert filter now supports large samples
74 Imager 0.61_02 - 28 November 2007
77 - major TIFF support re-work
78 http://rt.cpan.org/Ticket/Display.html?id=20329
80 - added a C level image interface for accessing samples from 1-32
81 bits, exposed this at the perl level in getsamples()
83 - the conv filter now works at floating point precision for high bit
86 - added is_bilevel method to test whether an image should be written as
87 a bilevel image if the image format supports it.
89 - added -log-stderr as an Imager import list option
91 - added some important types to Imager::APIRef
93 - added test_image_double() to Imager::Test
97 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
100 - the scale() method with qtype mixing now handles images with an
101 alpha channel correctly.
103 - fixed a broken link from the "animated GIF" entry in the concept index.
104 Thanks to Slaven Rezic.
105 http://rt.cpan.org/Ticket/Display.html?id=30889
107 - on some perl's the infix expression parser test would fail due to
108 actions in the grammar returning false. Made sure all actions return
110 Thanks to Richard Fairhurst for spending a lot of time in tracking
112 http://rt.cpan.org/Public/Bug/Display.html?id=29562
114 Imager 0.61 - 5 November 2007
117 - added samples/gifscale.pl, which adjusts the screen size/position tags
118 when scaling an animated gif
119 http://rt.cpan.org/Ticket/Display.html?id=27591
123 - correct handling of sz in matrix_transform() - this should allow
124 perspective type transformations to work now.
125 http://rt.cpan.org/Ticket/Display.html?id=29936
127 - prevent a cast to integer warning on x64 builds in datatypes.c
128 also fixed some other type warnings
129 https://rt.cpan.org/Ticket/Display.html?id=30204
131 - some sub-directory tests depended on files produced by the parent
133 http://rt.cpan.org/Ticket/Display.html?id=30203
135 - Imager::Font::Wrap doesn't correctly set savepos
136 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
137 http://rt.cpan.org/Ticket/Display.html?id=29771
139 - test 171 in t/t01introvert.t was failing on perls configured to
141 http://rt.cpan.org/Ticket/Display.html?id=29413
143 - the code for the transform2() uminus operator was missing a break.
144 Added tests for better code coverage of the ops.
145 http://rt.cpan.org/Ticket/Display.html?id=29296
147 - the SGI RLE compression code could overflow its compression buffer
148 http://rt.cpan.org/Ticket/Display.html?id=30334
150 - the 32-bit output function used by the SGI code only handled values
151 under 0x10000. This was most noticable when writing large RLE images.
152 http://rt.cpan.org/Ticket/Display.html?id=30335
154 - validate chan_count for chans == NULL for each of the i_gsamp()
156 http://rt.cpan.org/Ticket/Display.html?id=28985
158 - attempt to work around the test failure at
159 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
160 http://rt.cpan.org/Ticket/Display.html?id=29562
162 - improve the error messages produced when attempting to read or write
163 an unknown image file format.
164 http://rt.cpan.org/Ticket/Display.html?id=30103
166 - improve the transform2() documentation
167 http://rt.cpan.org/Ticket/Display.html?id=29267
169 - correctly generate the author key in META.yml
170 http://rt.cpan.org/Ticket/Display.html?id=30377
172 - correctly blend a rotated (or matrix_transformed()) image when
173 performing interpolation in the presence of an alpha channel.
174 Also corrected the centring of the rotated image on the output
177 Imager 0.60 - 30 August 2007
180 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
181 now has full SGI RGB image format, including RLE and 16-bit/sample
183 https://rt.cpan.org/Ticket/Display.html?id=8666
185 - logging functions are now available in the API
187 - applied Gabriel Vasseur's patch
188 added documentation, further tests, and support for greyscale images
189 Obviously problems are my fault :)
190 https://rt.cpan.org/Ticket/Display.html?id=28142
192 - the mask for ICO/CUR images is now applied as an alpha channel to
193 the returned image. For the old behaviour, supply ico_masked => 0
194 to read() or read_multi(). This should be less confusing when
195 using Imager as a general image processor.
196 https://rt.cpan.org/Ticket/Display.html?id=29001
200 - in some cases it's possible for giflib/libungif to return color
201 indexes outside the range of colors defined by the image's palette.
202 We now expand the palette to match the indexes used.
203 Thanks to Gabriel Vasseur for reporting this.
205 - fixed various memory leaks that could occur when failing to read png,
206 jpeg, bmp or tga files.
208 - to avoid confusion, channels not present in the image are returned as
209 zero by getscanline(). This has no effect on the C level i_glin()
210 and i_glinf() API functions which continue to not set the unused
213 - the convert() method now returns an image of the same sample size as
215 https://rt.cpan.org/Ticket/Display.html?id=28492
217 - remove repeated text in Imager::Files
218 http://rt.cpan.org/Ticket/Display.html?id=27589
220 - be even more explicit that scale() and friends don't modify the source
221 image, but return a new image.
222 http://rt.cpan.org/Ticket/Display.html?id=28570
224 - improve the error message from errstr() when you try to load a font
225 for which the driver hasn't been built in Imager.
226 http://rt.cpan.org/Ticket/Display.html?id=27571
228 - transparency is now enabled by default when writing GIF images
229 http://rt.cpan.org/Ticket/Display.html?id=27615
231 - Imager would not load on Windows 98
232 http://rt.cpan.org/Ticket/Display.html?id=27653
234 Imager 0.59 - 14 June 2007
239 - fixes a regression introduced by the fixes for RT 11972
240 http://rt.cpan.org/Ticket/Display.html?id=27546
242 - cropping outside the image would return an Imager object with
243 no low-level image object, instead of returning false.
244 Fixed by: Philip Gwyn (Leolo)
245 http://rt.cpan.org/Ticket/Display.html?id=27509
247 Imager 0.58 - 16 May 2007
250 No significant changes from 0.57_01.
252 Imager 0.57_01 - 11 May 2007
255 - added to_rgb16 to produce a 16-bit/sample version of an image
257 - improve freetype 1.x text output efficiency
261 - search another place for rgb.txt, and check all the places
262 Imager::Color checks when deciding whether to skip testing it
263 http://rt.cpan.org/Ticket/Display.html?id=26064
265 - use a convolution kernel size based on the stddev rather than a
266 fixed size when performing a gaussian blur
267 http://rt.cpan.org/Ticket/Display.html?id=25645
269 - document the difference() method's mindist parameter, and debug it.
271 - put the Imager release number in the Inline::C generated code to
272 regenerate Inline code when a new release of Imager is installed.
273 http://rt.cpan.org/Ticket/Display.html?id=26278
275 - fix rendering on alpha channel images for the FreeType 1.x driver.
276 http://rt.cpan.org/Ticket/Display.html?id=11972
278 - fix rendering on alpha channel images for the T1lib driver.
279 http://rt.cpan.org/Ticket/Display.html?id=11972
281 - reworked library probing, we can now set more than one probe
282 function for a library. Disabled the default (non-freetype-config)
283 library probe and added an extra probe function that searches for
284 both ft2build.h and whatever it includes, and adds -I as needed.
285 Hopefully this will fix build problems like
286 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
287 http://rt.cpan.org/Ticket/Display.html?id=26086
289 Imager 0.57 - 30 Apr 2007
292 This is a maintenence release fixing a security issue in Imager.
294 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
295 overflow in malloced memory. There will be further discussion of
296 this issue in the ticket below.
297 http://rt.cpan.org/Ticket/Display.html?id=26811
298 CVE-2007-2459 CVE-2007-2413
299 The descriptions at cve.mitre.org varied in quality, please see the
300 ticket at rt.cpan.org for a more accurate description of the issue.
302 Imager 0.56 - 1 Apr 2007
305 - added support for reading 16-bit/sample PGM/PPM images
307 - added support for writing 16-bit/sample PGM/PPM images
309 - improved performance of reading PBM/PGM/PPM images
311 - added support for writing PBM images if the image is paletted and
312 contains only black and white
314 - added a new make_colors value - "mono"
316 - switched from the svn log Changes to a manual Changes to reduce
319 - new sample code - samples/flasher.pl
323 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
324 was returning an image object with an extra reference, this
325 resulted in a memory leak.
326 http://rt.cpan.org/Ticket/Display.html?id=24992
328 - fix rendering on alpha channel images for the FreeType 2.x driver
329 http://rt.cpan.org/Ticket/Display.html?id=11972
331 - reading bmp files now consitently handles short reads. You can now
332 supply a parameter to treat a short read as successful and set
334 http://rt.cpan.org/Ticket/Display.html?id=8426
336 - previously, reading ASCII PBM files required spaces between samples,
337 even though the format doesn't require that
339 - improved documentation of the unsharpmask filter (I hope)
340 http://rt.cpan.org/Ticket/Display.html?id=25531
342 - force flushing of the output from i_tt_dump_names() and test output
343 in t/t35ttfont.t to prevent output from being mixed up.
344 https://rt.cpan.org/Ticket/Display.html?id=24859
346 - rewrite a conditional expression as an if() to hopefully work around
347 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
348 https://rt.cpan.org/Ticket/Display.html?id=25561
350 - avoid Data::Dumper in regops.perl to support older releases of perl
351 https://rt.cpan.org/Ticket/Display.html?id=24391
353 Imager 0.55 - 16 Dec 2006
356 This is primarily a bug fix release.
358 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
360 There is one new feature:
362 - the Win32 font driver now supports UTF8 (RT 22166)
363 http://www.cpanforum.com/threads/3276
364 http://rt.cpan.org/Ticket/Display.html?id=22166
366 Several bugs were fixed:
368 - the string() method would not output the string "0"
369 http://rt.cpan.org/Public/Bug/Display.html?id=21770
371 - fills.c was failing to compile on Solaris 10 (compiler unknown)
372 http://rt.cpan.org/Public/Bug/Display.html?id=21944
374 - the gif_disposal and gif_user_input tags weren't being read from
376 http://rt.cpan.org/Public/Bug/Display.html?id=22192
378 - gif.c was failing to build under MSVC
379 http://rt.cpan.org/Ticket/Display.html?id=23922
381 - in some cases strings passed to the string() method were treated as
382 terminated by NUL (chr 0)
383 http://rt.cpan.org/Public/Bug/Display.html?id=21770
385 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
386 that's the default build name for zlib on Win32.
387 http://rt.cpan.org/Ticket/Display.html?id=23064
389 - search $Config{incpath} for headers too, which we should have been
392 Win32 font driver fixes:
394 - the global descent value from bounding box was the wrong sign
395 http://www.cpanforum.com/threads/3276
397 - if the first or last glyph overflowed the left or right side of the
398 advance width they would be clipped
401 Imager 0.54 - 14 Sep 2006
404 This is primarily a feature release:
406 - a new qtype value 'mixing' has been added to the scale()
407 method. This is faster than 'normal', slower than 'preview'. This
408 is based on the method used by pnmscale, and seems to produce less
409 blurry results than normal.
410 http://rt.cpan.org/Public/Bug/Display.html?id=20677
412 - the rubthrough() method can now render onto images with an alpha
414 http://rt.cpan.org/Ticket/Display.html?id=20678
416 - the read_multi() method now falls back to calling doing a single
417 image read via the read() method and write_multi() will now fall
418 back to calling write() if a single image is supplied. This means
419 you can simply call the read_multi() or write_multi() functions
420 without having to check if the type is formatted by that method.
421 http://rt.cpan.org/Ticket/Display.html?id=19457
422 http://rt.cpan.org/Ticket/Display.html?id=19458
424 - the GIF loop extension can now be written. If you don't have
425 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
427 http://rt.cpan.org/Ticket/Display.html?id=21185
429 - getscanline() and setscanline() can now read/write palette index
430 based data from/to the image for paletted images, by setting type to
432 http://rt.cpan.org/Ticket/Display.html?id=20338
434 - we no longer hassle you to disable GIF support
435 http://rt.cpan.org/Ticket/Display.html?id=20687
437 - minor documentation fixes
440 Imager 0.53 - 26 Jul 2006
443 This is a bugfix release.
445 Some test code was left in a code path not covered by the test
446 suite. A test was added to cover this code path and the test code was
448 http://rt.cpan.org/Public/Bug/Display.html?id=20705
451 Imager 0.52 - 25 Jul 2006
454 This is primarily a feature release, but contains a fair few bug
457 - ability to read and write MS Windows ICO and CUR files
459 - you can now add file format plugins to support new file formats
461 - add POD coverage tests
463 - setcolors() and addcolors() now accept color names and so on
464 instead of requiring Imager::Color objects.
465 http://rt.cpan.org/Ticket/Display.html?id=20056
467 - flood_fill() can now fill to a specified border color instead of
468 just to the area the same color as the seed.
469 http://rt.cpan.org/Ticket/Display.html?id=19618
474 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
475 calculating the advance width.
476 http://rt.cpan.org/Public/Bug/Display.html?id=20554
478 - bounding_box for the T1 driver wasn't including leading and
479 trailing spaces in the bounding box as the other drivers did, it also
480 produced strange results for empty strings or strings containing only
483 - when reading CMYK jpeg images they were being transferred to the
484 image object as is, producing a four channel image. It only looked ok
485 due to an old still unfixed Photoshop bug. We now convert from the
486 inverted CMYK that photoshop (and Corel for example) produce into RGB.
487 http://rt.cpan.org/Ticket/Display.html?id=20416
489 - reading a CYMK TIFF would result in a 4 channel image, reading any
490 image with more than 4 channels (eg. RGB with 2 alpha channels) would
492 http://rt.cpan.org/Ticket/Display.html?id=20415
494 - added /usr/local/include to the default include search path, since
495 we were already searching /usr/local/lib for libraries.
497 And various minor fixes and documentation updates.
500 Imager 0.51 - 23 Apr 2006
503 - fix a validation bug when processing JPEG EXIF data that can cause
505 http://rt.cpan.org/Public/Bug/Display.html?id=18496
507 - fix mis-processing of the src_maxx and src_maxy parameters of the
509 http://rt.cpan.org/Public/Bug/Display.html?id=18712
511 - fix a problem in Imager's "smart" handling of the color parameter
513 http://rt.cpan.org/Public/Bug/Display.html?id=18561
516 Imager 0.50 - 29 Mar 2006
519 - CRITICAL: fixes a segmentation fault from attempting to write a 2
520 or 4 channel image to jpeg or a 2 channel image to tga where the
521 output is an in-memeory buffer.
522 http://rt.cpan.org/Public/Bug/Display.html?id=18397
524 - fixes an incorrect pointer parameter in the PNG code
525 http://rt.cpan.org/Public/Bug/Display.html?id=18051
527 - skip Inline::C tests when building in a directory with spaces
528 http://rt.cpan.org/Public/Bug/Display.html?id=18049
