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
11 - Imager::Matrix2d->translate() now only requires one of the x or y
13 http://rt.cpan.org/Ticket/Display.html?id=29937
15 Imager 0.62 - 10 December 2007
18 - Makefile.PL now expands ~/path supplied to --incpath or --libpath
19 to /path under your home directory.
20 http://rt.cpan.org/Ticket/Display.html?id=29484
22 - the old dynaload code used Mach API functions to load dynamic
23 libraries on Mac OS X. These APIs have been deprecated in OS X
24 10.5 and were causing some build problems.
25 So henceforth Imager uses the dlopen() family of functions, and you
26 will need version 10.3 or later of OS X.
28 - added the det() function to the transform2() engine.
29 added the sample quad_to_square.pl

35 - samples/gifscale.pl sourced the base value for gif_top from
37 Thanks to Eleneldil G. Arilou for pointing this out.
39 - t/t82inline.t no longer loads B at runtime, to work around a bug
40 in some 5.005_0[45] installations.
41 http://rt.cpan.org/Ticket/Display.html?id=30508
43 - work around Module::Depends::Intrusive bug #21229
44 http://rt.cpan.org/Ticket/Display.html?id=30520
46 - the hardinvert filter no-longer inverts the alpha channel.
47 http://rt.cpan.org/Ticket/Display.html?id=30002
49 - the hardinvert filter now supports large samples
51 Imager 0.61_02 - 28 November 2007
54 - major TIFF support re-work
55 http://rt.cpan.org/Ticket/Display.html?id=20329
57 - added a C level image interface for accessing samples from 1-32
58 bits, exposed this at the perl level in getsamples()
60 - the conv filter now works at floating point precision for high bit
63 - added is_bilevel method to test whether an image should be written as
64 a bilevel image if the image format supports it.
66 - added -log-stderr as an Imager import list option
68 - added some important types to Imager::APIRef
70 - added test_image_double() to Imager::Test
74 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
77 - the scale() method with qtype mixing now handles images with an
78 alpha channel correctly.
80 - fixed a broken link from the "animated GIF" entry in the concept index.
81 Thanks to Slaven Rezic.
82 http://rt.cpan.org/Ticket/Display.html?id=30889
84 - on some perl's the infix expression parser test would fail due to
85 actions in the grammar returning false. Made sure all actions return
87 Thanks to Richard Fairhurst for spending a lot of time in tracking
89 http://rt.cpan.org/Public/Bug/Display.html?id=29562
91 Imager 0.61 - 5 November 2007
94 - added samples/gifscale.pl, which adjusts the screen size/position tags
95 when scaling an animated gif
96 http://rt.cpan.org/Ticket/Display.html?id=27591
100 - correct handling of sz in matrix_transform() - this should allow
101 perspective type transformations to work now.
102 http://rt.cpan.org/Ticket/Display.html?id=29936
104 - prevent a cast to integer warning on x64 builds in datatypes.c
105 also fixed some other type warnings
106 https://rt.cpan.org/Ticket/Display.html?id=30204
108 - some sub-directory tests depended on files produced by the parent
110 http://rt.cpan.org/Ticket/Display.html?id=30203
112 - Imager::Font::Wrap doesn't correctly set savepos
113 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
114 http://rt.cpan.org/Ticket/Display.html?id=29771
116 - test 171 in t/t01introvert.t was failing on perls configured to
118 http://rt.cpan.org/Ticket/Display.html?id=29413
120 - the code for the transform2() uminus operator was missing a break.
121 Added tests for better code coverage of the ops.
122 http://rt.cpan.org/Ticket/Display.html?id=29296
124 - the SGI RLE compression code could overflow its compression buffer
125 http://rt.cpan.org/Ticket/Display.html?id=30334
127 - the 32-bit output function used by the SGI code only handled values
128 under 0x10000. This was most noticable when writing large RLE images.
129 http://rt.cpan.org/Ticket/Display.html?id=30335
131 - validate chan_count for chans == NULL for each of the i_gsamp()
133 http://rt.cpan.org/Ticket/Display.html?id=28985
135 - attempt to work around the test failure at
136 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
137 http://rt.cpan.org/Ticket/Display.html?id=29562
139 - improve the error messages produced when attempting to read or write
140 an unknown image file format.
141 http://rt.cpan.org/Ticket/Display.html?id=30103
143 - improve the transform2() documentation
144 http://rt.cpan.org/Ticket/Display.html?id=29267
146 - correctly generate the author key in META.yml
147 http://rt.cpan.org/Ticket/Display.html?id=30377
149 - correctly blend a rotated (or matrix_transformed()) image when
150 performing interpolation in the presence of an alpha channel.
151 Also corrected the centring of the rotated image on the output
154 Imager 0.60 - 30 August 2007
157 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
158 now has full SGI RGB image format, including RLE and 16-bit/sample
160 https://rt.cpan.org/Ticket/Display.html?id=8666
162 - logging functions are now available in the API
164 - applied Gabriel Vasseur's patch
165 added documentation, further tests, and support for greyscale images
166 Obviously problems are my fault :)
167 https://rt.cpan.org/Ticket/Display.html?id=28142
169 - the mask for ICO/CUR images is now applied as an alpha channel to
170 the returned image. For the old behaviour, supply ico_masked => 0
171 to read() or read_multi(). This should be less confusing when
172 using Imager as a general image processor.
173 https://rt.cpan.org/Ticket/Display.html?id=29001
177 - in some cases it's possible for giflib/libungif to return color
178 indexes outside the range of colors defined by the image's palette.
179 We now expand the palette to match the indexes used.
180 Thanks to Gabriel Vasseur for reporting this.
182 - fixed various memory leaks that could occur when failing to read png,
183 jpeg, bmp or tga files.
185 - to avoid confusion, channels not present in the image are returned as
186 zero by getscanline(). This has no effect on the C level i_glin()
187 and i_glinf() API functions which continue to not set the unused
190 - the convert() method now returns an image of the same sample size as
192 https://rt.cpan.org/Ticket/Display.html?id=28492
194 - remove repeated text in Imager::Files
195 http://rt.cpan.org/Ticket/Display.html?id=27589
197 - be even more explicit that scale() and friends don't modify the source
198 image, but return a new image.
199 http://rt.cpan.org/Ticket/Display.html?id=28570
201 - improve the error message from errstr() when you try to load a font
202 for which the driver hasn't been built in Imager.
203 http://rt.cpan.org/Ticket/Display.html?id=27571
205 - transparency is now enabled by default when writing GIF images
206 http://rt.cpan.org/Ticket/Display.html?id=27615
208 - Imager would not load on Windows 98
209 http://rt.cpan.org/Ticket/Display.html?id=27653
211 Imager 0.59 - 14 June 2007
216 - fixes a regression introduced by the fixes for RT 11972
217 http://rt.cpan.org/Ticket/Display.html?id=27546
219 - cropping outside the image would return an Imager object with
220 no low-level image object, instead of returning false.
221 Fixed by: Philip Gwyn (Leolo)
222 http://rt.cpan.org/Ticket/Display.html?id=27509
224 Imager 0.58 - 16 May 2007
227 No significant changes from 0.57_01.
229 Imager 0.57_01 - 11 May 2007
232 - added to_rgb16 to produce a 16-bit/sample version of an image
234 - improve freetype 1.x text output efficiency
238 - search another place for rgb.txt, and check all the places
239 Imager::Color checks when deciding whether to skip testing it
240 http://rt.cpan.org/Ticket/Display.html?id=26064
242 - use a convolution kernel size based on the stddev rather than a
243 fixed size when performing a gaussian blur
244 http://rt.cpan.org/Ticket/Display.html?id=25645
246 - document the difference() method's mindist parameter, and debug it.
248 - put the Imager release number in the Inline::C generated code to
249 regenerate Inline code when a new release of Imager is installed.
250 http://rt.cpan.org/Ticket/Display.html?id=26278
252 - fix rendering on alpha channel images for the FreeType 1.x driver.
253 http://rt.cpan.org/Ticket/Display.html?id=11972
255 - fix rendering on alpha channel images for the T1lib driver.
256 http://rt.cpan.org/Ticket/Display.html?id=11972
258 - reworked library probing, we can now set more than one probe
259 function for a library. Disabled the default (non-freetype-config)
260 library probe and added an extra probe function that searches for
261 both ft2build.h and whatever it includes, and adds -I as needed.
262 Hopefully this will fix build problems like
263 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
264 http://rt.cpan.org/Ticket/Display.html?id=26086
266 Imager 0.57 - 30 Apr 2007
269 This is a maintenence release fixing a security issue in Imager.
271 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
272 overflow in malloced memory. There will be further discussion of
273 this issue in the ticket below.
274 http://rt.cpan.org/Ticket/Display.html?id=26811
275 CVE-2007-2459 CVE-2007-2413
276 The descriptions at cve.mitre.org varied in quality, please see the
277 ticket at rt.cpan.org for a more accurate description of the issue.
279 Imager 0.56 - 1 Apr 2007
282 - added support for reading 16-bit/sample PGM/PPM images
284 - added support for writing 16-bit/sample PGM/PPM images
286 - improved performance of reading PBM/PGM/PPM images
288 - added support for writing PBM images if the image is paletted and
289 contains only black and white
291 - added a new make_colors value - "mono"
293 - switched from the svn log Changes to a manual Changes to reduce
296 - new sample code - samples/flasher.pl
300 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
301 was returning an image object with an extra reference, this
302 resulted in a memory leak.
303 http://rt.cpan.org/Ticket/Display.html?id=24992
305 - fix rendering on alpha channel images for the FreeType 2.x driver
306 http://rt.cpan.org/Ticket/Display.html?id=11972
308 - reading bmp files now consitently handles short reads. You can now
309 supply a parameter to treat a short read as successful and set
311 http://rt.cpan.org/Ticket/Display.html?id=8426
313 - previously, reading ASCII PBM files required spaces between samples,
314 even though the format doesn't require that
316 - improved documentation of the unsharpmask filter (I hope)
317 http://rt.cpan.org/Ticket/Display.html?id=25531
319 - force flushing of the output from i_tt_dump_names() and test output
320 in t/t35ttfont.t to prevent output from being mixed up.
321 https://rt.cpan.org/Ticket/Display.html?id=24859
323 - rewrite a conditional expression as an if() to hopefully work around
324 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
325 https://rt.cpan.org/Ticket/Display.html?id=25561
327 - avoid Data::Dumper in regops.perl to support older releases of perl
328 https://rt.cpan.org/Ticket/Display.html?id=24391
330 Imager 0.55 - 16 Dec 2006
333 This is primarily a bug fix release.
335 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
337 There is one new feature:
339 - the Win32 font driver now supports UTF8 (RT 22166)
340 http://www.cpanforum.com/threads/3276
341 http://rt.cpan.org/Ticket/Display.html?id=22166
343 Several bugs were fixed:
345 - the string() method would not output the string "0"
346 http://rt.cpan.org/Public/Bug/Display.html?id=21770
348 - fills.c was failing to compile on Solaris 10 (compiler unknown)
349 http://rt.cpan.org/Public/Bug/Display.html?id=21944
351 - the gif_disposal and gif_user_input tags weren't being read from
353 http://rt.cpan.org/Public/Bug/Display.html?id=22192
355 - gif.c was failing to build under MSVC
356 http://rt.cpan.org/Ticket/Display.html?id=23922
358 - in some cases strings passed to the string() method were treated as
359 terminated by NUL (chr 0)
360 http://rt.cpan.org/Public/Bug/Display.html?id=21770
362 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
363 that's the default build name for zlib on Win32.
364 http://rt.cpan.org/Ticket/Display.html?id=23064
366 - search $Config{incpath} for headers too, which we should have been
369 Win32 font driver fixes:
371 - the global descent value from bounding box was the wrong sign
372 http://www.cpanforum.com/threads/3276
374 - if the first or last glyph overflowed the left or right side of the
375 advance width they would be clipped
378 Imager 0.54 - 14 Sep 2006
381 This is primarily a feature release:
383 - a new qtype value 'mixing' has been added to the scale()
384 method. This is faster than 'normal', slower than 'preview'. This
385 is based on the method used by pnmscale, and seems to produce less
386 blurry results than normal.
387 http://rt.cpan.org/Public/Bug/Display.html?id=20677
389 - the rubthrough() method can now render onto images with an alpha
391 http://rt.cpan.org/Ticket/Display.html?id=20678
393 - the read_multi() method now falls back to calling doing a single
394 image read via the read() method and write_multi() will now fall
395 back to calling write() if a single image is supplied. This means
396 you can simply call the read_multi() or write_multi() functions
397 without having to check if the type is formatted by that method.
398 http://rt.cpan.org/Ticket/Display.html?id=19457
399 http://rt.cpan.org/Ticket/Display.html?id=19458
401 - the GIF loop extension can now be written. If you don't have
402 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
404 http://rt.cpan.org/Ticket/Display.html?id=21185
406 - getscanline() and setscanline() can now read/write palette index
407 based data from/to the image for paletted images, by setting type to
409 http://rt.cpan.org/Ticket/Display.html?id=20338
411 - we no longer hassle you to disable GIF support
412 http://rt.cpan.org/Ticket/Display.html?id=20687
414 - minor documentation fixes
417 Imager 0.53 - 26 Jul 2006
420 This is a bugfix release.
422 Some test code was left in a code path not covered by the test
423 suite. A test was added to cover this code path and the test code was
425 http://rt.cpan.org/Public/Bug/Display.html?id=20705
428 Imager 0.52 - 25 Jul 2006
431 This is primarily a feature release, but contains a fair few bug
434 - ability to read and write MS Windows ICO and CUR files
436 - you can now add file format plugins to support new file formats
438 - add POD coverage tests
440 - setcolors() and addcolors() now accept color names and so on
441 instead of requiring Imager::Color objects.
442 http://rt.cpan.org/Ticket/Display.html?id=20056
444 - flood_fill() can now fill to a specified border color instead of
445 just to the area the same color as the seed.
446 http://rt.cpan.org/Ticket/Display.html?id=19618
451 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
452 calculating the advance width.
453 http://rt.cpan.org/Public/Bug/Display.html?id=20554
455 - bounding_box for the T1 driver wasn't including leading and
456 trailing spaces in the bounding box as the other drivers did, it also
457 produced strange results for empty strings or strings containing only
460 - when reading CMYK jpeg images they were being transferred to the
461 image object as is, producing a four channel image. It only looked ok
462 due to an old still unfixed Photoshop bug. We now convert from the
463 inverted CMYK that photoshop (and Corel for example) produce into RGB.
464 http://rt.cpan.org/Ticket/Display.html?id=20416
466 - reading a CYMK TIFF would result in a 4 channel image, reading any
467 image with more than 4 channels (eg. RGB with 2 alpha channels) would
469 http://rt.cpan.org/Ticket/Display.html?id=20415
471 - added /usr/local/include to the default include search path, since
472 we were already searching /usr/local/lib for libraries.
474 And various minor fixes and documentation updates.
477 Imager 0.51 - 23 Apr 2006
480 - fix a validation bug when processing JPEG EXIF data that can cause
482 http://rt.cpan.org/Public/Bug/Display.html?id=18496
484 - fix mis-processing of the src_maxx and src_maxy parameters of the
486 http://rt.cpan.org/Public/Bug/Display.html?id=18712
488 - fix a problem in Imager's "smart" handling of the color parameter
490 http://rt.cpan.org/Public/Bug/Display.html?id=18561
493 Imager 0.50 - 29 Mar 2006
496 - CRITICAL: fixes a segmentation fault from attempting to write a 2
497 or 4 channel image to jpeg or a 2 channel image to tga where the
498 output is an in-memeory buffer.
499 http://rt.cpan.org/Public/Bug/Display.html?id=18397
501 - fixes an incorrect pointer parameter in the PNG code
502 http://rt.cpan.org/Public/Bug/Display.html?id=18051
504 - skip Inline::C tests when building in a directory with spaces
505 http://rt.cpan.org/Public/Bug/Display.html?id=18049
