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 Imager 0.60 - 30 August 2007
23 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
24 now has full SGI RGB image format, including RLE and 16-bit/sample
26 https://rt.cpan.org/Ticket/Display.html?id=8666
28 - logging functions are now available in the API
30 - applied Gabriel Vasseur's patch
31 added documentation, further tests, and support for greyscale images
32 Obviously problems are my fault :)
33 https://rt.cpan.org/Ticket/Display.html?id=28142
35 - the mask for ICO/CUR images is now applied as an alpha channel to
36 the returned image. For the old behaviour, supply ico_masked => 0
37 to read() or read_multi(). This should be less confusing when
38 using Imager as a general image processor.
39 https://rt.cpan.org/Ticket/Display.html?id=29001
43 - in some cases it's possible for giflib/libungif to return color
44 indexes outside the range of colors defined by the image's palette.
45 We now expand the palette to match the indexes used.
46 Thanks to Gabriel Vasseur for reporting this.
48 - fixed various memory leaks that could occur when failing to read png,
49 jpeg, bmp or tga files.
51 - to avoid confusion, channels not present in the image are returned as
52 zero by getscanline(). This has no effect on the C level i_glin()
53 and i_glinf() API functions which continue to not set the unused
56 - the convert() method now returns an image of the same sample size as
58 https://rt.cpan.org/Ticket/Display.html?id=28492
60 - remove repeated text in Imager::Files
61 http://rt.cpan.org/Ticket/Display.html?id=27589
63 - be even more explicit that scale() and friends don't modify the source
64 image, but return a new image.
65 http://rt.cpan.org/Ticket/Display.html?id=28570
67 - improve the error message from errstr() when you try to load a font
68 for which the driver hasn't been built in Imager.
69 http://rt.cpan.org/Ticket/Display.html?id=27571
71 - transparency is now enabled by default when writing GIF images
72 http://rt.cpan.org/Ticket/Display.html?id=27615
74 - Imager would not load on Windows 98
75 http://rt.cpan.org/Ticket/Display.html?id=27653
77 Imager 0.59 - 14 June 2007
82 - fixes a regression introduced by the fixes for RT 11972
83 http://rt.cpan.org/Ticket/Display.html?id=27546
85 - cropping outside the image would return an Imager object with
86 no low-level image object, instead of returning false.
87 Fixed by: Philip Gwyn (Leolo)
88 http://rt.cpan.org/Ticket/Display.html?id=27509
90 Imager 0.58 - 16 May 2007
93 No significant changes from 0.57_01.
95 Imager 0.57_01 - 11 May 2007
98 - added to_rgb16 to produce a 16-bit/sample version of an image
100 - improve freetype 1.x text output efficiency
104 - search another place for rgb.txt, and check all the places
105 Imager::Color checks when deciding whether to skip testing it
106 http://rt.cpan.org/Ticket/Display.html?id=26064
108 - use a convolution kernel size based on the stddev rather than a
109 fixed size when performing a gaussian blur
110 http://rt.cpan.org/Ticket/Display.html?id=25645
112 - document the difference() method's mindist parameter, and debug it.
114 - put the Imager release number in the Inline::C generated code to
115 regenerate Inline code when a new release of Imager is installed.
116 http://rt.cpan.org/Ticket/Display.html?id=26278
118 - fix rendering on alpha channel images for the FreeType 1.x driver.
119 http://rt.cpan.org/Ticket/Display.html?id=11972
121 - fix rendering on alpha channel images for the T1lib driver.
122 http://rt.cpan.org/Ticket/Display.html?id=11972
124 - reworked library probing, we can now set more than one probe
125 function for a library. Disabled the default (non-freetype-config)
126 library probe and added an extra probe function that searches for
127 both ft2build.h and whatever it includes, and adds -I as needed.
128 Hopefully this will fix build problems like
129 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
130 http://rt.cpan.org/Ticket/Display.html?id=26086
132 Imager 0.57 - 30 Apr 2007
135 This is a maintenence release fixing a security issue in Imager.
137 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
138 overflow in malloced memory. There will be further discussion of
139 this issue in the ticket below.
140 http://rt.cpan.org/Ticket/Display.html?id=26811
141 CVE-2007-2459 CVE-2007-2413
142 The descriptions at cve.mitre.org varied in quality, please see the
143 ticket at rt.cpan.org for a more accurate description of the issue.
145 Imager 0.56 - 1 Apr 2007
148 - added support for reading 16-bit/sample PGM/PPM images
150 - added support for writing 16-bit/sample PGM/PPM images
152 - improved performance of reading PBM/PGM/PPM images
154 - added support for writing PBM images if the image is paletted and
155 contains only black and white
157 - added a new make_colors value - "mono"
159 - switched from the svn log Changes to a manual Changes to reduce
162 - new sample code - samples/flasher.pl
166 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
167 was returning an image object with an extra reference, this
168 resulted in a memory leak.
169 http://rt.cpan.org/Ticket/Display.html?id=24992
171 - fix rendering on alpha channel images for the FreeType 2.x driver
172 http://rt.cpan.org/Ticket/Display.html?id=11972
174 - reading bmp files now consitently handles short reads. You can now
175 supply a parameter to treat a short read as successful and set
177 http://rt.cpan.org/Ticket/Display.html?id=8426
179 - previously, reading ASCII PBM files required spaces between samples,
180 even though the format doesn't require that
182 - improved documentation of the unsharpmask filter (I hope)
183 http://rt.cpan.org/Ticket/Display.html?id=25531
185 - force flushing of the output from i_tt_dump_names() and test output
186 in t/t35ttfont.t to prevent output from being mixed up.
187 https://rt.cpan.org/Ticket/Display.html?id=24859
189 - rewrite a conditional expression as an if() to hopefully work around
190 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
191 https://rt.cpan.org/Ticket/Display.html?id=25561
193 - avoid Data::Dumper in regops.perl to support older releases of perl
194 https://rt.cpan.org/Ticket/Display.html?id=24391
196 Imager 0.55 - 16 Dec 2006
199 This is primarily a bug fix release.
201 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
203 There is one new feature:
205 - the Win32 font driver now supports UTF8 (RT 22166)
206 http://www.cpanforum.com/threads/3276
207 http://rt.cpan.org/Ticket/Display.html?id=22166
209 Several bugs were fixed:
211 - the string() method would not output the string "0"
212 http://rt.cpan.org/Public/Bug/Display.html?id=21770
214 - fills.c was failing to compile on Solaris 10 (compiler unknown)
215 http://rt.cpan.org/Public/Bug/Display.html?id=21944
217 - the gif_disposal and gif_user_input tags weren't being read from
219 http://rt.cpan.org/Public/Bug/Display.html?id=22192
221 - gif.c was failing to build under MSVC
222 http://rt.cpan.org/Ticket/Display.html?id=23922
224 - in some cases strings passed to the string() method were treated as
225 terminated by NUL (chr 0)
226 http://rt.cpan.org/Public/Bug/Display.html?id=21770
228 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
229 that's the default build name for zlib on Win32.
230 http://rt.cpan.org/Ticket/Display.html?id=23064
232 - search $Config{incpath} for headers too, which we should have been
235 Win32 font driver fixes:
237 - the global descent value from bounding box was the wrong sign
238 http://www.cpanforum.com/threads/3276
240 - if the first or last glyph overflowed the left or right side of the
241 advance width they would be clipped
244 Imager 0.54 - 14 Sep 2006
247 This is primarily a feature release:
249 - a new qtype value 'mixing' has been added to the scale()
250 method. This is faster than 'normal', slower than 'preview'. This
251 is based on the method used by pnmscale, and seems to produce less
252 blurry results than normal.
253 http://rt.cpan.org/Public/Bug/Display.html?id=20677
255 - the rubthrough() method can now render onto images with an alpha
257 http://rt.cpan.org/Ticket/Display.html?id=20678
259 - the read_multi() method now falls back to calling doing a single
260 image read via the read() method and write_multi() will now fall
261 back to calling write() if a single image is supplied. This means
262 you can simply call the read_multi() or write_multi() functions
263 without having to check if the type is formatted by that method.
264 http://rt.cpan.org/Ticket/Display.html?id=19457
265 http://rt.cpan.org/Ticket/Display.html?id=19458
267 - the GIF loop extension can now be written. If you don't have
268 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
270 http://rt.cpan.org/Ticket/Display.html?id=21185
272 - getscanline() and setscanline() can now read/write palette index
273 based data from/to the image for paletted images, by setting type to
275 http://rt.cpan.org/Ticket/Display.html?id=20338
277 - we no longer hassle you to disable GIF support
278 http://rt.cpan.org/Ticket/Display.html?id=20687
280 - minor documentation fixes
283 Imager 0.53 - 26 Jul 2006
286 This is a bugfix release.
288 Some test code was left in a code path not covered by the test
289 suite. A test was added to cover this code path and the test code was
291 http://rt.cpan.org/Public/Bug/Display.html?id=20705
294 Imager 0.52 - 25 Jul 2006
297 This is primarily a feature release, but contains a fair few bug
300 - ability to read and write MS Windows ICO and CUR files
302 - you can now add file format plugins to support new file formats
304 - add POD coverage tests
306 - setcolors() and addcolors() now accept color names and so on
307 instead of requiring Imager::Color objects.
308 http://rt.cpan.org/Ticket/Display.html?id=20056
310 - flood_fill() can now fill to a specified border color instead of
311 just to the area the same color as the seed.
312 http://rt.cpan.org/Ticket/Display.html?id=19618
317 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
318 calculating the advance width.
319 http://rt.cpan.org/Public/Bug/Display.html?id=20554
321 - bounding_box for the T1 driver wasn't including leading and
322 trailing spaces in the bounding box as the other drivers did, it also
323 produced strange results for empty strings or strings containing only
326 - when reading CMYK jpeg images they were being transferred to the
327 image object as is, producing a four channel image. It only looked ok
328 due to an old still unfixed Photoshop bug. We now convert from the
329 inverted CMYK that photoshop (and Corel for example) produce into RGB.
330 http://rt.cpan.org/Ticket/Display.html?id=20416
332 - reading a CYMK TIFF would result in a 4 channel image, reading any
333 image with more than 4 channels (eg. RGB with 2 alpha channels) would
335 http://rt.cpan.org/Ticket/Display.html?id=20415
337 - added /usr/local/include to the default include search path, since
338 we were already searching /usr/local/lib for libraries.
340 And various minor fixes and documentation updates.
343 Imager 0.51 - 23 Apr 2006
346 - fix a validation bug when processing JPEG EXIF data that can cause
348 http://rt.cpan.org/Public/Bug/Display.html?id=18496
350 - fix mis-processing of the src_maxx and src_maxy parameters of the
352 http://rt.cpan.org/Public/Bug/Display.html?id=18712
354 - fix a problem in Imager's "smart" handling of the color parameter
356 http://rt.cpan.org/Public/Bug/Display.html?id=18561
359 Imager 0.50 - 29 Mar 2006
362 - CRITICAL: fixes a segmentation fault from attempting to write a 2
363 or 4 channel image to jpeg or a 2 channel image to tga where the
364 output is an in-memeory buffer.
365 http://rt.cpan.org/Public/Bug/Display.html?id=18397
367 - fixes an incorrect pointer parameter in the PNG code
368 http://rt.cpan.org/Public/Bug/Display.html?id=18051
370 - skip Inline::C tests when building in a directory with spaces
371 http://rt.cpan.org/Public/Bug/Display.html?id=18049
