TC
3Incompatible changes:
4
5 - the return value of setpixel() has changed.
6
7 Previously the return values for undrawable pixels vs caller errors
8 changed depending on whether you used the multiple pixel calling
9 mechanism, or the single pixel mechanism.
10
11 Now:
12
13 - for an invalid parameter, such as an unknown colour, or missing
14 parameter, an empty list (or undef in scalar context) is
15 returned, and errstr() is set,
16
17 - otherwise the number of pixels drawn is returned. If none of
18 the pixels could be drawn (they were all outside the image), "0
19 but true" is returned.

22
23Other changes:
24
6ba09ab9
TC
25 - when drawing on an image with an alpha channel where the source
26 minimum is greater than zero, Imager would read from beyond the end
27 of a malloc() allocated buffer. In rare circumstances this could
28 lead to some of the source image not being written to the target
29 image, or possibly to a segmentation fault.
30 I don't believe this has any security concerns beyond that.
31
0d052fd9
TC
32 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
33 text drawn would be nonsense. This would also read beyond the end
34 of a malloced buffer.
35
13671b17
TC
36 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
37 truncated early.
38 https://rt.cpan.org/Ticket/Display.html?id=88993
39
d6f4e964
TC
40 - Imager::Font::Wrap no longer requires the image parameter.

f84f86a2
TC
43 - a documentation typo fix in Imager::Transformations
44 Thanks to Adrian Yee.

46
0179ecd6
TC
47 - Image::Probe, Imager's internal module for probing library
48 locations now searches the directories specified by LD_RUN_PATH,
49 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
50 and the corresponing s/\blib$/include/ directories for header
51 files.

62 - PNG: treat a version mismatch between headers and library as a
63 probe failure.
64 https://rt.cpan.org/Ticket/Display.html?id=86659
65
8e90f677
TC
66 - PNG: the check for benign error support is more complex than a
67 simple library version check, check for the appropriate macro.
68 Thanks for Slaven Rezic for following up on my CPAN Testers result
69 queries.

78 - TIFF: handle SampleFormat = 2 by translating the signed integer
79 values to unsigned by flipping their sign bits.
80
81 Handle SampleFormat = 3 where possible.
82
83 SampleFormat is ignored for paletted images.
84
237d9e03
TC
85 Mixed SampleFormat are handled incorrectly, since libtiff returns
86 only the first SampleFormat value, and an image with both an alpha
87 channel and SampleFormat = 2 for color channels probably has a
88 different SampleFormat for the alpha channel.

face45e7 92 - XS clean up:
29969fa2 93 https://rt.cpan.org/Ticket/Display.html?id=69243
face45e7 94
237d9e03 95 - Imager::Color's rgba() method now returns its values as integers
face45e7
TC
96 instead of floating point. (IV instead of NV).
97
19e9591b
TC
98 - The XS for i_map() and i_matrix_transform() now use the AV *
99 typemap instead of rolling their own.
100
75cebca8
TC
101 - The XS for DSO_call() now uses the HV * typemap instead of
102 rolling it's own.
103
0aaa8b4d
TC
104 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
105 i_gradgen() now use a new T_AVARRAY typemap that greatly
106 simplifies the XS code.
face45e7 107
ccd01d49
TC
108 - many other minor XS changes
109
face45e7 110 - some XS code formatting

TC
112 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
113 now renders in alpha-combining mode, to match antialiased output.
114 https://rt.cpan.org/Ticket/Display.html?id=73359
b482243a 115
8db7b6fa
TC
116 - add sample code and cookbook notes for drawing a blurred drop-shadow.
117
118 - add support for libpng 1.6, which changed the defaults for
119 reporting some types of error.
120 https://rt.cpan.org/Ticket/Display.html?id=85746

TC
122 - FT2: use gsamp/psamp() to transfer pixels from the work image to
123 the output image instead of gpix/ppix.

129Imager 0.96 - 19 May 2013
130===========
131
c2e251d9
TC
132 - rearrange Imager's test files.
133 https://rt.cpan.org/Ticket/Display.html?id=84596
134
135 - Imager::Probe::_gcc_lib_paths now forces C locale.
136 A sufficiently recent gcc prints localized keys for the search
137 paths, which avoids that localization.
138 https://rt.cpan.org/Ticket/Display.html?id=84963
139
140 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
141 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
142 and true.
143 https://rt.cpan.org/Ticket/Display.html?id=85262
144 reported by Andreas König
145
146 - add a test for unclosed POD in C source, and fix the errors it
147 found.
148 https://rt.cpan.org/Ticket/Display.html?id=74875
149
150 - fix some spelling errors detected by the newer aspell in Debian
151 Wheezy.
152
153 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
154 thanks to gregor herrmann <gregoa@debian.org>
155 https://rt.cpan.org/Ticket/Display.html?id=85413
156
157 - add a test for standard =head1 commands and fix the errors found

TC
159Imager 0.95 - 19 Apr 2013
160===========
161
0a2956ab
TC
162 - handle the SVf_UTF8 flag correctly on magic strings passed to
163 Imager::IO's write() and raw_write() methods.
164 This may misbehave in perl 5.6.x since the UTF8 flag may not be
165 visible in the main SV after SvGETMAGIC().
166 https://rt.cpan.org/Ticket/Display.html?id=83438
167
168 - document that bounding_box() ignores the transformation matrix
169 supplied to tranform() for fonts.
170 https://rt.cpan.org/Ticket/Display.html?id=84106

TC
172Imager 0.94_02 - 5 Apr 2013
173==============
174
1540d1d4
TC
175 - enable debug logging for the standard font tests
176
177 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
178 due to a bug in that version of perl.
179
180 - don't test for read() failing on a write-only handle in 5.8.x and
181 earlier, this was fixed in change 862083f7e4 in perl.
182
183 - report the version of Inline found during testing (an attempt to
184 diagnose some intermittent failures.)

186Imager 0.94_01 - 2 Mar 2013
187==============
188
14a4ea18 189 - NOTE: possibly backward incompatible:
3dcf7595
TC
190 support reading from/writing to perl filehandes that aren't raw
191 files.
192
193 This allows Imager's I/O to honour handles with layers such as
194 gzip, scalar file handles or tied file handles.
195
14a4ea18 196 This is backward incompatible in that previous Imager would simply
3dcf7595
TC
197 use fileno() to retrieve the fd for the file and call write(2) etc
198 on it directly.
04d8c568
TC
199 https://rt.cpan.org/Ticket/Display.html?id=78843
200
201 - moved most of README to lib/Imager/Install.pod which should make it
202 more accessible to the "web" generation, also significantly updated
203 and re-worked it.
3dcf7595 204
ca96f811
TC
205 - updated README's for the separately distributed modules to refer to
206 Imager::Install, and that they need -dev versions of packages
207 https://rt.cpan.org/Ticket/Display.html?id=81265
208
26e8a226
TC
209 - the JPEG test code now reports the compile-time library version
210
41125e7d
TC
211 - avoid a possible compiler optimization issue on CentOS 5.9 i386 by
212 rearranging (and mildly optimizing) some code.

c732ffa5
TC
221 - drawing text to a channel with FT2 would draw with random coverage
222 due to an uninitialized alpha channel.
223
224 - marked the function pointer underlying the mm_log() API with the
225 correct gcc magic and fixed the resulting warnings.
226
227 - fixed some other compiler warnings
228
14a4ea18
TC
229 - Imager::Font::W32 now properly reports text drawing errors
230 https://rt.cpan.org/Ticket/Display.html?id=70098
231
0a2956ab 232 - handle the SVf_UTF8 flag correctly on magic (eg. overloaded)
14a4ea18
TC
233 strings passed as text to draw(), bounding_box(), has_chars(),
234 glyph_names() (where supported) in each of the font drivers.
0a2956ab
TC
235 This may misbehave in perl 5.6.x since the UTF8 flag may not be
236 visible in the main SV after SvGETMAGIC().

239Imager 0.94 - 15 Dec 2012
240=========================
241
242Variations on some of these changes were included in development
243releases.
244
4be61824
TC
245 - improved thread safety
246 - the internal error stack and log file handle are now in a per-thread
247 context object
248 - JPEG now captures IPTC information in a thread-safe way
249 - avoid globals where possible for warning capture in libtiff
244725cf
TC
250 - use a mutex to avoid re-entering thread-unsafe giflib
251 - use a mutex to avoid re-entering thread-unsafe tifflib
252 - use a mutex to avoid re-entering thread-unsafe T1Lib
253 - use a library handle per thread for freetype 2.
0124c060 254 - use an engine handle per thread for freetype 1.x.
0eebfd59
TC
255 - originally these changes broke ABI compatibility, this has been
256 restored.
abffffed 257
6254ad14
TC
258 - clarify the return value of getpixel();
259 https://rt.cpan.org/Ticket/Display.html?id=81198
260
261 - fixed a race condition in parallel testing for T1
262
263 - fixed a bug in handling yoff for untransformed image-based fills
264
265 - documentation improvements for Imager::Fill
266
5e8f194e
TC
267 - FT2: report the library version while testing.

269Imager 0.93 - 15 Oct 2012
270===========
271
272Bug fixes:
71fbe41a
TC
273
274 - previously a transparency enabled GIF write (the default) would
275 always use a GIF89a header even if none of the images were
276 transparent.
7a5f7bc6 277
b2f967ef
TC
278 - previously the probe step for freetype-config would fail on cygwin
279
b2f967ef
TC
280 - catch an invalid matrix parameter to convert() instead of crashing
281 https://rt.cpan.org/Ticket/Display.html?id=79922
282
283 - remove the 16-bit/sample limitation from the documentation for
284 setsamples(), it hasn't applied for many releases.
285 https://rt.cpan.org/Ticket/Display.html?id=79989
286
9673d97e
TC
287 - don't copy setsamples() data parameter, it may be a large scalar
288 https://rt.cpan.org/Ticket/Display.html?id=79990

8c323994
TC
293 - pass the --verbose command-line option through to Imager::Probe in
294 sub-module's Makefile.PLs

TC
297Enhancements:
298
299 - support for giflib 5.0. (5.0.1 and later)
300 https://rt.cpan.org/Ticket/Display.html?id=79029
301 The giflib API Imager uses doesn't have a mechanism to set the
302 header version in 5.0.0.
303
304 - update the GIF library probe code to check for the new giflib 5.0.1
305 EGifSetGifVersion() function, and to check for the giflib 4.2.0
306 uninitialized gif89 bug.
307 https://rt.cpan.org/Ticket/Display.html?id=79679
308 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
309
310 - avoid static variables when capturing IPTC data from JPEG files
311
312 - match Imager::Font;:T1's error message translations to those from
313 later versions of T1Lib.
314
315 - for libtiff versions that support extended warning handlers (3.8.0
316 or later), use them to avoid some global variables.
317
318 - note Image::ExifTool for better metadata support.

321Imager 0.92 - 14 Aug 2012
322===========
323
b1c75496
TC
324 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
325 correctly for both probing and runtime.
326 https://rt.cpan.org/Ticket/Display.html?id=77672
327

334
ef84bb32 335Bug fixes:
38742a13 336
289d65f4
TC
337 - The size of rotated images is no longer rounded up so aggressively.
338 Added rounding to the linear interpolation done for rotate() and
339 matrix_transform() for 1 and 3 channel 8-bit images.
340 Adjusted the two tranlate matrices used to build the final rotation
341 matrix to use the distance between the outlier pixels rather than
342 the pixel dimensions (ie. dimension-1).
343 With all of this the output of rotate(degrees => 270) on an 8-bit
344 image exactly matches the output of rotate(right => 270).
345 https://rt.cpan.org/Ticket/Display.html?id=77063
346
ef84bb32
TC
347Other changes:
348
349 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
350 internals, those names only matter for the XS interface.
351
352 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
353 the API level compiled into a loadable module such as
354 Imager::File::GIF doesn't match that of Imager. Previously it
355 could be difficult to determine exactly which module was failing to
356 load.
357 https://rt.cpan.org/Ticket/Display.html?id=77173
358
359 - added Imager->check_file_limits() as an interface to the
360 i_int_check_image_file_limits() API.
361
362 - Imager->set_file_limits(reset => 1) now resets the limits to the
363 defaults rather than setting them all to unlimited.
364
365 - wrote a brief security note as Imager::Security
366 https://rt.cpan.org/Ticket/Display.html?id=68910
367
6f31dd14 368Imager 0.90 - 30 Apr 2012
7c4464f5
TC
369===========
370
371Bug fixes:
372
373 - Imager::Test::is_imaged() attempted to process an "epsilon"
374 parameter but the prototype didn't allow for the extra parameter.
375 Corrected the prototype.
376
29b38678
TC
377 - when downconverting samples (eg. from floating point to 8 bit)
378 Imager now rounds the sample value rather than attempting to
379 allocate input values over output values equally. The old
380 behaviour had the probably surprising effect of converting a
381 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
382 2.
383 This may result in slightly different 8 or 16-bit output images.
384
e2a86bac
TC
385 - BI_BITFIELD BMP images were handled incorrectly, both in
386 incorrectly calculating the space required for the masks and in
387 processing the image data itself.
388 https://rt.cpan.org/Ticket/Display.html?id=76736
389
390 - some odd width BMP BI_RLE4 images use run lengths that run one off
391 the edge of the image. Imager now allows this, discarding the
392 extra column.
393
394 - odd length RLE4 runs in BMP images were decoded incorrectly.
395
82eb0687
TC
396 - pkg-config could sometimes return a library that was in a directory
397 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
398 If no -L is included in the pkg-config library information check if
399 EU::MM can find the library, and if not, search our configured
400 directories and insert that into the library flags.
401 https://rt.cpan.org/Ticket/Display.html?id=75869
402
de50f459
TC
403 - Imager::Probe can now probe for libraries with dependent libraries,
404 common for static linking, eg. libpng requires libz.
405 https://rt.cpan.org/Ticket/Display.html?id=74043
406
407 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
408
409 - added alternative probe configurations that try to link libz, to
410 handle a statically linked libpng.
411 https://rt.cpan.org/Ticket/Display.html?id=74043
412
413 - if a probe includes testcode, Imager::Probe now checks that code as
414 part of the process of checking each configuration rather than as a
415 post test of the found configuration. This allows alternate
416 configurations to be checked if a matching but non-working
417 configuration is found.
418 https://rt.cpan.org/Ticket/Display.html?id=74043
419
9d5ff8a6
TC
420Other changes:
421
422 - when reading or writing images via callbacks, the default callbacks
423 now push an error message indicating that a required callback was
424 called but not supplied.
425 https://rt.cpan.org/Ticket/Display.html?id=76782
426
427 - clarify which callbacks are required for reading and writing TIFF
428 images.
429
430 - improve logging for creation of callback I/O layers.
431
de50f459
TC
432 - a little more documentation for Imager::Probe.
433
594f5933
TC
434 - the i_get_file_background() and i_get_file_backgroundf() APIs now
435 return int to indicate whether the i_background tag was found.
436
1b46057d
TC
437 - PNG rework
438 - improve error reporting
439 - add png_interlace, png_bits tags
440 - read paletted images as paletted images, including transparency
441 - read 1 bit greyscale images as a type suitable for other file
442 handlers to write as bilevel
443 - read 16 bit/sample PNG as 16-bit/sample Imager images
444 - write "bilevel" paletted images as 1 bit grayscale images
445 - write paletted images as paletted images
446 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
447 images
448 - improved metadata support

493 - setsamples() is now a true complement to getsamples() - it can
494 write 8-bit or floating point samples from a scalar or array
495 reference. This adds i_psamp() and i_psampf() to the C level API.
496
497 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
498 changed to make better use of the typemap, but these aren't part of
499 the perl level API anyway. There were no changes to the C level
500 interfaces to these functions.

655 - io_glue I/O buffering re-work:
656
657 - reorganize io_glue to do it's own buffering by default
658
659 - the unbuffered functions are available as i_io_raw_read() (or
660 raw_read() from perl) etc but are not recommended for typical
661 use.
662
663 - use the new i_io_peekn() when checking for file magic to avoid
664 seek, allowing Imager to detect the file type and read the file
665 from an unseekable stream (for formats that don't use random
666 access)
667
668 - added several new I/O layer API functions.
669
670 - fix the TGA performance problem, most noticably on Win32
671 https://rt.cpan.org/Ticket/Display.html?id=70037
672
673 - TIFF now uses wrapper functions of the correct types to avoid casts
674 https://rt.cpan.org/Ticket/Display.html?id=69912
675
676 - the callback IO object did its own buffering, controlled by the
677 maxbuffer parameter supplied to the read() and write() methods.
678 This buffering has been removed, to avoid redundancy with the
679 common io_glue buffering. This also avoids a bug in that code
680 which could rarely pass a zero length to the read callback and
681 then panic about the result.
682
683 - the callback IO object now tests the result of calling the close
684 callback, which should return true for success.
685
686 - the PNM reader did its own buffering. This buffering has been
687 removed to avoid redundancy with the common io_glue buffering.
688
689 - previously the read handlers for fd and callback I/O layers would
690 call the underlying interface (POSIX read or your supplied callback)
691 until it filled the buffer. It now only makes one call.
692
693 - added public constructors for I/O layer objects (see Imager::IO)
694
695 - all core file handlers now use the i_io_foo() wrappers to gain
696 access to buffered I/O rather than calling the I/O layer
697 callbacks directly.
698
699 - all core file handlers now check for error on close.
700
701 - Backward compatibility: if you hava custom file handlers, you can
702 use i_io_write() etc since they're available as macros in older
703 versions of Imager.
704
705 - eliminate the final remnants of io_glue_commit_types().
706
707 - bump IMAGER_API_VERSION, since the above may break assumptions.
708
709 - removed the long unused i_gen_reader() and i_gen_writer() utility
710 functions.

773Development release as a sanity check for the types re-work.

TC
774
775Massive types re-work:
776
777 - the type used internally for pixel co-ordinates and image sizes is
778 now 64-bit on 64-bit platforms (at least sane ones).
779
780 - size_t is now used consistently for memory block sizes.
781
782 - since this changes the binary interface, the Imager API version has
783 been incremented. Any module that uses the API will need to be
784 rebuilt. In most cases that will be enough, but calls to any APIs
785 that take a pointer to image sizes may need source changes.
786
787 - you should be able to create very large images on 64-bit systems,
788 if you have enough memory. Successfully created a 32768 x 49192 x
789 3 channel image, filled with a tiled image and scaled it. The
790 unscaled image was also successfully saved to a JPEG.
791
792 - check the image size before attempting to write BMP, GIF, JPEG,
793 PNG, SGI, TGA, TIFF images.
794
795 - correctly handle reading TGA images over 32767 pixels wide or tall.
796
797Incidental changes:
798
799 - the gif_left and gif_top tags are now clamped to non-negative
800 values when writing a GIF image.
801
802 - removed dead callback read/write code
803
804The default maximum memory size when reading files is now 1G.

1414 - Possible security issue: The floating point sample path for image

1420 - check that the result of fileno($fh) is defined rather than simply
1421 true when read() or write() is supplied with an fh parameter.
1422 http://rt.cpan.org/Ticket/Display.html?id=35139
1423
1424 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1425 resulting in a SIGSEGV when attempting to scale an image to a size
1426 too large to fit in memory. This is a NULL pointer access issue,
1427 not a buffer overflow.
1428 Added a check for the failure.
1429 scale_calculate() (and hence scale()) will now fail if any of the
1430 scale size parameters are a reference.

1442This release primarily contains changes to improve ease of use -
1443rather than you having to convert images to the appropriate number of
1444channels, Imager handles it internally. How to handle drawing colors
1445and the default combine mode is a thornier problem left for some other
1446release.

TC
1451 - moved the imtoc.perl code into Imager::Preprocess
1452
1453 - paste() and rubthrough() now adapt the source image data to the
1454 destination, so you can now safely paste/rubthrough from greyscale
1455 images to color images or back, or from alpha channel images to
1456 noalpha channels or back.
1457 https://rt.cpan.org/Ticket/Display.html?id=30908
1458
1459 - rubthrough() now falls back to pasting when the source doesn't have
1460 an alpha channel. This effectively treats the source as having a
1461 max alpha channel, the right thing to do.
1462 http://rt.cpan.org/Ticket/Display.html?id=29944
1463
1464 - re-worked most of the area filling code to use a common set of
1465 functions when filling.
1466 Corrected normal combine mode.
1467 Rewrote most of the combine modes to match the way the SVG draft
1468 defines them with respect to a translucent source and destination.
1469 Added tests for translucent source and destination.
1470 Added tests to check 8-bit/sample and double/sample combines work
1471 similarly.

1507 - some TGA images weren't being detected correctly as TGA images
1508 https://rt.cpan.org/Ticket/Display.html?id=32925
1509
1510 - handling of the left-over bit for 16-bit/pixel TGA images has been
1511 changed to match the behaviour of the GIMP. Previously the bit
1512 being set was treated as an opaque pixel, but one user reported a
1513 problem with loading such an image. I haven't been able to find any
1514 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1515 I'll match it's behaviour. See issue 114913 in the GIMP's
1516 bugzilla.

1526 - the old dynaload code used Mach API functions to load dynamic
1527 libraries on Mac OS X. These APIs have been deprecated in OS X
1528 10.5 and were causing some build problems.

1530 will need version 10.3 or later of OS X.

1762 - reworked library probing, we can now set more than one probe
1763 function for a library. Disabled the default (non-freetype-config)
1764 library probe and added an extra probe function that searches for
1765 both ft2build.h and whatever it includes, and adds -I as needed.
1766 Hopefully this will fix build problems like

1802Bug fixes:
1803
1804 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)

1834Imager 0.55 - 16 Dec 2006
1835===========
1836
1837This is primarily a bug fix release.
1838
1839Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1840
1841There is one new feature:
1842
1843 - the Win32 font driver now supports UTF8 (RT 22166)
1844 http://www.cpanforum.com/threads/3276
1845 http://rt.cpan.org/Ticket/Display.html?id=22166
1846
1847Several bugs were fixed:
1848
1849 - the string() method would not output the string "0"
1850 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1851
1852 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1853 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1854
1855 - the gif_disposal and gif_user_input tags weren't being read from
1856 the file correctly
1857 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1858
1859 - gif.c was failing to build under MSVC
1860 http://rt.cpan.org/Ticket/Display.html?id=23922
1861
1862 - in some cases strings passed to the string() method were treated as
1863 terminated by NUL (chr 0)
1864 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1865
1866 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1867 that's the default build name for zlib on Win32.
1868 http://rt.cpan.org/Ticket/Display.html?id=23064
1869
1870 - search $Config{incpath} for headers too, which we should have been
1871 doing all along.
1872
1873Win32 font driver fixes:
1874
1875 - the global descent value from bounding box was the wrong sign
1876 http://www.cpanforum.com/threads/3276
1877
1878 - if the first or last glyph overflowed the left or right side of the
1879 advance width they would be clipped
1880
1881
1882Imager 0.54 - 14 Sep 2006
1883===========
1884
1885This is primarily a feature release:
1886
1887 - a new qtype value 'mixing' has been added to the scale()
1888 method. This is faster than 'normal', slower than 'preview'. This
1889 is based on the method used by pnmscale, and seems to produce less
1890 blurry results than normal.
1891 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1892
1893 - the rubthrough() method can now render onto images with an alpha
1894 channel.
1895 http://rt.cpan.org/Ticket/Display.html?id=20678
1896
1897 - the read_multi() method now falls back to calling doing a single
1898 image read via the read() method and write_multi() will now fall
1899 back to calling write() if a single image is supplied. This means
1900 you can simply call the read_multi() or write_multi() functions
1901 without having to check if the type is formatted by that method.
1902 http://rt.cpan.org/Ticket/Display.html?id=19457
1903 http://rt.cpan.org/Ticket/Display.html?id=19458
1904
1905 - the GIF loop extension can now be written. If you don't have
1906 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1907 should upgrade.
1908 http://rt.cpan.org/Ticket/Display.html?id=21185
1909
1910 - getscanline() and setscanline() can now read/write palette index
1911 based data from/to the image for paletted images, by setting type to
1912 'index'.
1913 http://rt.cpan.org/Ticket/Display.html?id=20338
1914
1915 - we no longer hassle you to disable GIF support
1916 http://rt.cpan.org/Ticket/Display.html?id=20687
1917
1918 - minor documentation fixes
1919
1920
1921Imager 0.53 - 26 Jul 2006
1922===========
1923
1924This is a bugfix release.
1925
1926Some test code was left in a code path not covered by the test
1927suite. A test was added to cover this code path and the test code was
1928removed.

1930
1931
1932Imager 0.52 - 25 Jul 2006
1933===========
1934
1935This is primarily a feature release, but contains a fair few bug
1936fixes, new features:
1937
1938 - ability to read and write MS Windows ICO and CUR files
1939
1940 - you can now add file format plugins to support new file formats
1941
1942 - add POD coverage tests
1943
1944 - setcolors() and addcolors() now accept color names and so on
1945 instead of requiring Imager::Color objects.
1946 http://rt.cpan.org/Ticket/Display.html?id=20056
1947
1948 - flood_fill() can now fill to a specified border color instead of
1949 just to the area the same color as the seed.
1950 http://rt.cpan.org/Ticket/Display.html?id=19618
1951
1952
1953Bug fixes:
1954
1955 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1956 calculating the advance width.
1957 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1958
1959 - bounding_box for the T1 driver wasn't including leading and
1960 trailing spaces in the bounding box as the other drivers did, it also
1961 produced strange results for empty strings or strings containing only
1962 spaces
1963
1964 - when reading CMYK jpeg images they were being transferred to the
1965 image object as is, producing a four channel image. It only looked ok
1966 due to an old still unfixed Photoshop bug. We now convert from the
1967 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1968 http://rt.cpan.org/Ticket/Display.html?id=20416
1969
1970 - reading a CYMK TIFF would result in a 4 channel image, reading any
1971 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1972 result in an error.
1973 http://rt.cpan.org/Ticket/Display.html?id=20415
1974
1975 - added /usr/local/include to the default include search path, since
1976 we were already searching /usr/local/lib for libraries.
1977
1978And various minor fixes and documentation updates.
1979
1980

1987
1988 - fix mis-processing of the src_maxx and src_maxy parameters of the
1989 paste() method
