1 Imager release history. Older releases can be found in Changes.old
3 Imager 0.61 - unreleased
6 - added samples/gifscale.pl, which adjusts the screen size/position tags
7 when scaling an animated gif
8 http://rt.cpan.org/Ticket/Display.html?id=27591
12 - correct handling of sz in matrix_transform() - this should allow
13 perspective type transformations to work now.
14 http://rt.cpan.org/Ticket/Display.html?id=29936
16 - prevent a cast to integer warning on x64 builds in datatypes.c
17 also fixed some other type warnings
18 https://rt.cpan.org/Ticket/Display.html?id=30204
20 - some sub-directory tests depended on files produced by the parent
22 http://rt.cpan.org/Ticket/Display.html?id=30203
24 - Imager::Font::Wrap doesn't correctly set savepos
25 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
26 http://rt.cpan.org/Ticket/Display.html?id=29771
28 - test 171 in t/t01introvert.t was failing on perls configured to
30 http://rt.cpan.org/Ticket/Display.html?id=29413
32 - the code for the transform2() uminus operator was missing a break.
33 Added tests for better code coverage of the ops.
34 http://rt.cpan.org/Ticket/Display.html?id=29296
36 Imager 0.60 - 30 August 2007
39 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
40 now has full SGI RGB image format, including RLE and 16-bit/sample
42 https://rt.cpan.org/Ticket/Display.html?id=8666
44 - logging functions are now available in the API
46 - applied Gabriel Vasseur's patch
47 added documentation, further tests, and support for greyscale images
48 Obviously problems are my fault :)
49 https://rt.cpan.org/Ticket/Display.html?id=28142
51 - the mask for ICO/CUR images is now applied as an alpha channel to
52 the returned image. For the old behaviour, supply ico_masked => 0
53 to read() or read_multi(). This should be less confusing when
54 using Imager as a general image processor.
55 https://rt.cpan.org/Ticket/Display.html?id=29001
59 - in some cases it's possible for giflib/libungif to return color
60 indexes outside the range of colors defined by the image's palette.
61 We now expand the palette to match the indexes used.
62 Thanks to Gabriel Vasseur for reporting this.
64 - fixed various memory leaks that could occur when failing to read png,
65 jpeg, bmp or tga files.
67 - to avoid confusion, channels not present in the image are returned as
68 zero by getscanline(). This has no effect on the C level i_glin()
69 and i_glinf() API functions which continue to not set the unused
72 - the convert() method now returns an image of the same sample size as
74 https://rt.cpan.org/Ticket/Display.html?id=28492
76 - remove repeated text in Imager::Files
77 http://rt.cpan.org/Ticket/Display.html?id=27589
79 - be even more explicit that scale() and friends don't modify the source
80 image, but return a new image.
81 http://rt.cpan.org/Ticket/Display.html?id=28570
83 - improve the error message from errstr() when you try to load a font
84 for which the driver hasn't been built in Imager.
85 http://rt.cpan.org/Ticket/Display.html?id=27571
87 - transparency is now enabled by default when writing GIF images
88 http://rt.cpan.org/Ticket/Display.html?id=27615
90 - Imager would not load on Windows 98
91 http://rt.cpan.org/Ticket/Display.html?id=27653
93 Imager 0.59 - 14 June 2007
98 - fixes a regression introduced by the fixes for RT 11972
99 http://rt.cpan.org/Ticket/Display.html?id=27546
101 - cropping outside the image would return an Imager object with
102 no low-level image object, instead of returning false.
103 Fixed by: Philip Gwyn (Leolo)
104 http://rt.cpan.org/Ticket/Display.html?id=27509
106 Imager 0.58 - 16 May 2007
109 No significant changes from 0.57_01.
111 Imager 0.57_01 - 11 May 2007
114 - added to_rgb16 to produce a 16-bit/sample version of an image
116 - improve freetype 1.x text output efficiency
120 - search another place for rgb.txt, and check all the places
121 Imager::Color checks when deciding whether to skip testing it
122 http://rt.cpan.org/Ticket/Display.html?id=26064
124 - use a convolution kernel size based on the stddev rather than a
125 fixed size when performing a gaussian blur
126 http://rt.cpan.org/Ticket/Display.html?id=25645
128 - document the difference() method's mindist parameter, and debug it.
130 - put the Imager release number in the Inline::C generated code to
131 regenerate Inline code when a new release of Imager is installed.
132 http://rt.cpan.org/Ticket/Display.html?id=26278
134 - fix rendering on alpha channel images for the FreeType 1.x driver.
135 http://rt.cpan.org/Ticket/Display.html?id=11972
137 - fix rendering on alpha channel images for the T1lib driver.
138 http://rt.cpan.org/Ticket/Display.html?id=11972
140 - reworked library probing, we can now set more than one probe
141 function for a library. Disabled the default (non-freetype-config)
142 library probe and added an extra probe function that searches for
143 both ft2build.h and whatever it includes, and adds -I as needed.
144 Hopefully this will fix build problems like
145 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
146 http://rt.cpan.org/Ticket/Display.html?id=26086
148 Imager 0.57 - 30 Apr 2007
151 This is a maintenence release fixing a security issue in Imager.
153 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
154 overflow in malloced memory. There will be further discussion of
155 this issue in the ticket below.
156 http://rt.cpan.org/Ticket/Display.html?id=26811
157 CVE-2007-2459 CVE-2007-2413
158 The descriptions at cve.mitre.org varied in quality, please see the
159 ticket at rt.cpan.org for a more accurate description of the issue.
161 Imager 0.56 - 1 Apr 2007
164 - added support for reading 16-bit/sample PGM/PPM images
166 - added support for writing 16-bit/sample PGM/PPM images
168 - improved performance of reading PBM/PGM/PPM images
170 - added support for writing PBM images if the image is paletted and
171 contains only black and white
173 - added a new make_colors value - "mono"
175 - switched from the svn log Changes to a manual Changes to reduce
178 - new sample code - samples/flasher.pl
182 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
183 was returning an image object with an extra reference, this
184 resulted in a memory leak.
185 http://rt.cpan.org/Ticket/Display.html?id=24992
187 - fix rendering on alpha channel images for the FreeType 2.x driver
188 http://rt.cpan.org/Ticket/Display.html?id=11972
190 - reading bmp files now consitently handles short reads. You can now
191 supply a parameter to treat a short read as successful and set
193 http://rt.cpan.org/Ticket/Display.html?id=8426
195 - previously, reading ASCII PBM files required spaces between samples,
196 even though the format doesn't require that
198 - improved documentation of the unsharpmask filter (I hope)
199 http://rt.cpan.org/Ticket/Display.html?id=25531
201 - force flushing of the output from i_tt_dump_names() and test output
202 in t/t35ttfont.t to prevent output from being mixed up.
203 https://rt.cpan.org/Ticket/Display.html?id=24859
205 - rewrite a conditional expression as an if() to hopefully work around
206 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
207 https://rt.cpan.org/Ticket/Display.html?id=25561
209 - avoid Data::Dumper in regops.perl to support older releases of perl
210 https://rt.cpan.org/Ticket/Display.html?id=24391
212 Imager 0.55 - 16 Dec 2006
215 This is primarily a bug fix release.
217 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
219 There is one new feature:
221 - the Win32 font driver now supports UTF8 (RT 22166)
222 http://www.cpanforum.com/threads/3276
223 http://rt.cpan.org/Ticket/Display.html?id=22166
225 Several bugs were fixed:
227 - the string() method would not output the string "0"
228 http://rt.cpan.org/Public/Bug/Display.html?id=21770
230 - fills.c was failing to compile on Solaris 10 (compiler unknown)
231 http://rt.cpan.org/Public/Bug/Display.html?id=21944
233 - the gif_disposal and gif_user_input tags weren't being read from
235 http://rt.cpan.org/Public/Bug/Display.html?id=22192
237 - gif.c was failing to build under MSVC
238 http://rt.cpan.org/Ticket/Display.html?id=23922
240 - in some cases strings passed to the string() method were treated as
241 terminated by NUL (chr 0)
242 http://rt.cpan.org/Public/Bug/Display.html?id=21770
244 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
245 that's the default build name for zlib on Win32.
246 http://rt.cpan.org/Ticket/Display.html?id=23064
248 - search $Config{incpath} for headers too, which we should have been
251 Win32 font driver fixes:
253 - the global descent value from bounding box was the wrong sign
254 http://www.cpanforum.com/threads/3276
256 - if the first or last glyph overflowed the left or right side of the
257 advance width they would be clipped
260 Imager 0.54 - 14 Sep 2006
263 This is primarily a feature release:
265 - a new qtype value 'mixing' has been added to the scale()
266 method. This is faster than 'normal', slower than 'preview'. This
267 is based on the method used by pnmscale, and seems to produce less
268 blurry results than normal.
269 http://rt.cpan.org/Public/Bug/Display.html?id=20677
271 - the rubthrough() method can now render onto images with an alpha
273 http://rt.cpan.org/Ticket/Display.html?id=20678
275 - the read_multi() method now falls back to calling doing a single
276 image read via the read() method and write_multi() will now fall
277 back to calling write() if a single image is supplied. This means
278 you can simply call the read_multi() or write_multi() functions
279 without having to check if the type is formatted by that method.
280 http://rt.cpan.org/Ticket/Display.html?id=19457
281 http://rt.cpan.org/Ticket/Display.html?id=19458
283 - the GIF loop extension can now be written. If you don't have
284 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
286 http://rt.cpan.org/Ticket/Display.html?id=21185
288 - getscanline() and setscanline() can now read/write palette index
289 based data from/to the image for paletted images, by setting type to
291 http://rt.cpan.org/Ticket/Display.html?id=20338
293 - we no longer hassle you to disable GIF support
294 http://rt.cpan.org/Ticket/Display.html?id=20687
296 - minor documentation fixes
299 Imager 0.53 - 26 Jul 2006
302 This is a bugfix release.
304 Some test code was left in a code path not covered by the test
305 suite. A test was added to cover this code path and the test code was
307 http://rt.cpan.org/Public/Bug/Display.html?id=20705
310 Imager 0.52 - 25 Jul 2006
313 This is primarily a feature release, but contains a fair few bug
316 - ability to read and write MS Windows ICO and CUR files
318 - you can now add file format plugins to support new file formats
320 - add POD coverage tests
322 - setcolors() and addcolors() now accept color names and so on
323 instead of requiring Imager::Color objects.
324 http://rt.cpan.org/Ticket/Display.html?id=20056
326 - flood_fill() can now fill to a specified border color instead of
327 just to the area the same color as the seed.
328 http://rt.cpan.org/Ticket/Display.html?id=19618
333 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
334 calculating the advance width.
335 http://rt.cpan.org/Public/Bug/Display.html?id=20554
337 - bounding_box for the T1 driver wasn't including leading and
338 trailing spaces in the bounding box as the other drivers did, it also
339 produced strange results for empty strings or strings containing only
342 - when reading CMYK jpeg images they were being transferred to the
343 image object as is, producing a four channel image. It only looked ok
344 due to an old still unfixed Photoshop bug. We now convert from the
345 inverted CMYK that photoshop (and Corel for example) produce into RGB.
346 http://rt.cpan.org/Ticket/Display.html?id=20416
348 - reading a CYMK TIFF would result in a 4 channel image, reading any
349 image with more than 4 channels (eg. RGB with 2 alpha channels) would
351 http://rt.cpan.org/Ticket/Display.html?id=20415
353 - added /usr/local/include to the default include search path, since
354 we were already searching /usr/local/lib for libraries.
356 And various minor fixes and documentation updates.
359 Imager 0.51 - 23 Apr 2006
362 - fix a validation bug when processing JPEG EXIF data that can cause
364 http://rt.cpan.org/Public/Bug/Display.html?id=18496
366 - fix mis-processing of the src_maxx and src_maxy parameters of the
368 http://rt.cpan.org/Public/Bug/Display.html?id=18712
370 - fix a problem in Imager's "smart" handling of the color parameter
372 http://rt.cpan.org/Public/Bug/Display.html?id=18561
375 Imager 0.50 - 29 Mar 2006
378 - CRITICAL: fixes a segmentation fault from attempting to write a 2
379 or 4 channel image to jpeg or a 2 channel image to tga where the
380 output is an in-memeory buffer.
381 http://rt.cpan.org/Public/Bug/Display.html?id=18397
383 - fixes an incorrect pointer parameter in the PNG code
384 http://rt.cpan.org/Public/Bug/Display.html?id=18051
386 - skip Inline::C tests when building in a directory with spaces
387 http://rt.cpan.org/Public/Bug/Display.html?id=18049
