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