1 Imager release history. Older releases can be found in Changes.old
3 Imager 0.62 - not yet release
7 - Imager::Fountain couldn't read GIMP gradient files with 10 or more
10 - the scale() method with qtype mixing now handles images with an
11 alpha channel correctly.
13 Imager 0.61 - 5 November 2007
16 - added samples/gifscale.pl, which adjusts the screen size/position tags
17 when scaling an animated gif
18 http://rt.cpan.org/Ticket/Display.html?id=27591
22 - correct handling of sz in matrix_transform() - this should allow
23 perspective type transformations to work now.
24 http://rt.cpan.org/Ticket/Display.html?id=29936
26 - prevent a cast to integer warning on x64 builds in datatypes.c
27 also fixed some other type warnings
28 https://rt.cpan.org/Ticket/Display.html?id=30204
30 - some sub-directory tests depended on files produced by the parent
32 http://rt.cpan.org/Ticket/Display.html?id=30203
34 - Imager::Font::Wrap doesn't correctly set savepos
35 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
36 http://rt.cpan.org/Ticket/Display.html?id=29771
38 - test 171 in t/t01introvert.t was failing on perls configured to
40 http://rt.cpan.org/Ticket/Display.html?id=29413
42 - the code for the transform2() uminus operator was missing a break.
43 Added tests for better code coverage of the ops.
44 http://rt.cpan.org/Ticket/Display.html?id=29296
46 - the SGI RLE compression code could overflow its compression buffer
47 http://rt.cpan.org/Ticket/Display.html?id=30334
49 - the 32-bit output function used by the SGI code only handled values
50 under 0x10000. This was most noticable when writing large RLE images.
51 http://rt.cpan.org/Ticket/Display.html?id=30335
53 - validate chan_count for chans == NULL for each of the i_gsamp()
55 http://rt.cpan.org/Ticket/Display.html?id=28985
57 - attempt to work around the test failure at
58 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
59 http://rt.cpan.org/Ticket/Display.html?id=29562
61 - improve the error messages produced when attempting to read or write
62 an unknown image file format.
63 http://rt.cpan.org/Ticket/Display.html?id=30103
65 - improve the transform2() documentation
66 http://rt.cpan.org/Ticket/Display.html?id=29267
68 - correctly generate the author key in META.yml
69 http://rt.cpan.org/Ticket/Display.html?id=30377
71 - correctly blend a rotated (or matrix_transformed()) image when
72 performing interpolation in the presence of an alpha channel.
73 Also corrected the centring of the rotated image on the output
76 Imager 0.60 - 30 August 2007
79 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
80 now has full SGI RGB image format, including RLE and 16-bit/sample
82 https://rt.cpan.org/Ticket/Display.html?id=8666
84 - logging functions are now available in the API
86 - applied Gabriel Vasseur's patch
87 added documentation, further tests, and support for greyscale images
88 Obviously problems are my fault :)
89 https://rt.cpan.org/Ticket/Display.html?id=28142
91 - the mask for ICO/CUR images is now applied as an alpha channel to
92 the returned image. For the old behaviour, supply ico_masked => 0
93 to read() or read_multi(). This should be less confusing when
94 using Imager as a general image processor.
95 https://rt.cpan.org/Ticket/Display.html?id=29001
99 - in some cases it's possible for giflib/libungif to return color
100 indexes outside the range of colors defined by the image's palette.
101 We now expand the palette to match the indexes used.
102 Thanks to Gabriel Vasseur for reporting this.
104 - fixed various memory leaks that could occur when failing to read png,
105 jpeg, bmp or tga files.
107 - to avoid confusion, channels not present in the image are returned as
108 zero by getscanline(). This has no effect on the C level i_glin()
109 and i_glinf() API functions which continue to not set the unused
112 - the convert() method now returns an image of the same sample size as
114 https://rt.cpan.org/Ticket/Display.html?id=28492
116 - remove repeated text in Imager::Files
117 http://rt.cpan.org/Ticket/Display.html?id=27589
119 - be even more explicit that scale() and friends don't modify the source
120 image, but return a new image.
121 http://rt.cpan.org/Ticket/Display.html?id=28570
123 - improve the error message from errstr() when you try to load a font
124 for which the driver hasn't been built in Imager.
125 http://rt.cpan.org/Ticket/Display.html?id=27571
127 - transparency is now enabled by default when writing GIF images
128 http://rt.cpan.org/Ticket/Display.html?id=27615
130 - Imager would not load on Windows 98
131 http://rt.cpan.org/Ticket/Display.html?id=27653
133 Imager 0.59 - 14 June 2007
138 - fixes a regression introduced by the fixes for RT 11972
139 http://rt.cpan.org/Ticket/Display.html?id=27546
141 - cropping outside the image would return an Imager object with
142 no low-level image object, instead of returning false.
143 Fixed by: Philip Gwyn (Leolo)
144 http://rt.cpan.org/Ticket/Display.html?id=27509
146 Imager 0.58 - 16 May 2007
149 No significant changes from 0.57_01.
151 Imager 0.57_01 - 11 May 2007
154 - added to_rgb16 to produce a 16-bit/sample version of an image
156 - improve freetype 1.x text output efficiency
160 - search another place for rgb.txt, and check all the places
161 Imager::Color checks when deciding whether to skip testing it
162 http://rt.cpan.org/Ticket/Display.html?id=26064
164 - use a convolution kernel size based on the stddev rather than a
165 fixed size when performing a gaussian blur
166 http://rt.cpan.org/Ticket/Display.html?id=25645
168 - document the difference() method's mindist parameter, and debug it.
170 - put the Imager release number in the Inline::C generated code to
171 regenerate Inline code when a new release of Imager is installed.
172 http://rt.cpan.org/Ticket/Display.html?id=26278
174 - fix rendering on alpha channel images for the FreeType 1.x driver.
175 http://rt.cpan.org/Ticket/Display.html?id=11972
177 - fix rendering on alpha channel images for the T1lib driver.
178 http://rt.cpan.org/Ticket/Display.html?id=11972
180 - reworked library probing, we can now set more than one probe
181 function for a library. Disabled the default (non-freetype-config)
182 library probe and added an extra probe function that searches for
183 both ft2build.h and whatever it includes, and adds -I as needed.
184 Hopefully this will fix build problems like
185 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
186 http://rt.cpan.org/Ticket/Display.html?id=26086
188 Imager 0.57 - 30 Apr 2007
191 This is a maintenence release fixing a security issue in Imager.
193 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
194 overflow in malloced memory. There will be further discussion of
195 this issue in the ticket below.
196 http://rt.cpan.org/Ticket/Display.html?id=26811
197 CVE-2007-2459 CVE-2007-2413
198 The descriptions at cve.mitre.org varied in quality, please see the
199 ticket at rt.cpan.org for a more accurate description of the issue.
201 Imager 0.56 - 1 Apr 2007
204 - added support for reading 16-bit/sample PGM/PPM images
206 - added support for writing 16-bit/sample PGM/PPM images
208 - improved performance of reading PBM/PGM/PPM images
210 - added support for writing PBM images if the image is paletted and
211 contains only black and white
213 - added a new make_colors value - "mono"
215 - switched from the svn log Changes to a manual Changes to reduce
218 - new sample code - samples/flasher.pl
222 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
223 was returning an image object with an extra reference, this
224 resulted in a memory leak.
225 http://rt.cpan.org/Ticket/Display.html?id=24992
227 - fix rendering on alpha channel images for the FreeType 2.x driver
228 http://rt.cpan.org/Ticket/Display.html?id=11972
230 - reading bmp files now consitently handles short reads. You can now
231 supply a parameter to treat a short read as successful and set
233 http://rt.cpan.org/Ticket/Display.html?id=8426
235 - previously, reading ASCII PBM files required spaces between samples,
236 even though the format doesn't require that
238 - improved documentation of the unsharpmask filter (I hope)
239 http://rt.cpan.org/Ticket/Display.html?id=25531
241 - force flushing of the output from i_tt_dump_names() and test output
242 in t/t35ttfont.t to prevent output from being mixed up.
243 https://rt.cpan.org/Ticket/Display.html?id=24859
245 - rewrite a conditional expression as an if() to hopefully work around
246 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
247 https://rt.cpan.org/Ticket/Display.html?id=25561
249 - avoid Data::Dumper in regops.perl to support older releases of perl
250 https://rt.cpan.org/Ticket/Display.html?id=24391
252 Imager 0.55 - 16 Dec 2006
255 This is primarily a bug fix release.
257 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
259 There is one new feature:
261 - the Win32 font driver now supports UTF8 (RT 22166)
262 http://www.cpanforum.com/threads/3276
263 http://rt.cpan.org/Ticket/Display.html?id=22166
265 Several bugs were fixed:
267 - the string() method would not output the string "0"
268 http://rt.cpan.org/Public/Bug/Display.html?id=21770
270 - fills.c was failing to compile on Solaris 10 (compiler unknown)
271 http://rt.cpan.org/Public/Bug/Display.html?id=21944
273 - the gif_disposal and gif_user_input tags weren't being read from
275 http://rt.cpan.org/Public/Bug/Display.html?id=22192
277 - gif.c was failing to build under MSVC
278 http://rt.cpan.org/Ticket/Display.html?id=23922
280 - in some cases strings passed to the string() method were treated as
281 terminated by NUL (chr 0)
282 http://rt.cpan.org/Public/Bug/Display.html?id=21770
284 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
285 that's the default build name for zlib on Win32.
286 http://rt.cpan.org/Ticket/Display.html?id=23064
288 - search $Config{incpath} for headers too, which we should have been
291 Win32 font driver fixes:
293 - the global descent value from bounding box was the wrong sign
294 http://www.cpanforum.com/threads/3276
296 - if the first or last glyph overflowed the left or right side of the
297 advance width they would be clipped
300 Imager 0.54 - 14 Sep 2006
303 This is primarily a feature release:
305 - a new qtype value 'mixing' has been added to the scale()
306 method. This is faster than 'normal', slower than 'preview'. This
307 is based on the method used by pnmscale, and seems to produce less
308 blurry results than normal.
309 http://rt.cpan.org/Public/Bug/Display.html?id=20677
311 - the rubthrough() method can now render onto images with an alpha
313 http://rt.cpan.org/Ticket/Display.html?id=20678
315 - the read_multi() method now falls back to calling doing a single
316 image read via the read() method and write_multi() will now fall
317 back to calling write() if a single image is supplied. This means
318 you can simply call the read_multi() or write_multi() functions
319 without having to check if the type is formatted by that method.
320 http://rt.cpan.org/Ticket/Display.html?id=19457
321 http://rt.cpan.org/Ticket/Display.html?id=19458
323 - the GIF loop extension can now be written. If you don't have
324 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
326 http://rt.cpan.org/Ticket/Display.html?id=21185
328 - getscanline() and setscanline() can now read/write palette index
329 based data from/to the image for paletted images, by setting type to
331 http://rt.cpan.org/Ticket/Display.html?id=20338
333 - we no longer hassle you to disable GIF support
334 http://rt.cpan.org/Ticket/Display.html?id=20687
336 - minor documentation fixes
339 Imager 0.53 - 26 Jul 2006
342 This is a bugfix release.
344 Some test code was left in a code path not covered by the test
345 suite. A test was added to cover this code path and the test code was
347 http://rt.cpan.org/Public/Bug/Display.html?id=20705
350 Imager 0.52 - 25 Jul 2006
353 This is primarily a feature release, but contains a fair few bug
356 - ability to read and write MS Windows ICO and CUR files
358 - you can now add file format plugins to support new file formats
360 - add POD coverage tests
362 - setcolors() and addcolors() now accept color names and so on
363 instead of requiring Imager::Color objects.
364 http://rt.cpan.org/Ticket/Display.html?id=20056
366 - flood_fill() can now fill to a specified border color instead of
367 just to the area the same color as the seed.
368 http://rt.cpan.org/Ticket/Display.html?id=19618
373 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
374 calculating the advance width.
375 http://rt.cpan.org/Public/Bug/Display.html?id=20554
377 - bounding_box for the T1 driver wasn't including leading and
378 trailing spaces in the bounding box as the other drivers did, it also
379 produced strange results for empty strings or strings containing only
382 - when reading CMYK jpeg images they were being transferred to the
383 image object as is, producing a four channel image. It only looked ok
384 due to an old still unfixed Photoshop bug. We now convert from the
385 inverted CMYK that photoshop (and Corel for example) produce into RGB.
386 http://rt.cpan.org/Ticket/Display.html?id=20416
388 - reading a CYMK TIFF would result in a 4 channel image, reading any
389 image with more than 4 channels (eg. RGB with 2 alpha channels) would
391 http://rt.cpan.org/Ticket/Display.html?id=20415
393 - added /usr/local/include to the default include search path, since
394 we were already searching /usr/local/lib for libraries.
396 And various minor fixes and documentation updates.
399 Imager 0.51 - 23 Apr 2006
402 - fix a validation bug when processing JPEG EXIF data that can cause
404 http://rt.cpan.org/Public/Bug/Display.html?id=18496
406 - fix mis-processing of the src_maxx and src_maxy parameters of the
408 http://rt.cpan.org/Public/Bug/Display.html?id=18712
410 - fix a problem in Imager's "smart" handling of the color parameter
412 http://rt.cpan.org/Public/Bug/Display.html?id=18561
415 Imager 0.50 - 29 Mar 2006
418 - CRITICAL: fixes a segmentation fault from attempting to write a 2
419 or 4 channel image to jpeg or a 2 channel image to tga where the
420 output is an in-memeory buffer.
421 http://rt.cpan.org/Public/Bug/Display.html?id=18397
423 - fixes an incorrect pointer parameter in the PNG code
424 http://rt.cpan.org/Public/Bug/Display.html?id=18051
426 - skip Inline::C tests when building in a directory with spaces
427 http://rt.cpan.org/Public/Bug/Display.html?id=18049
