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 Imager 0.60 - 30 August 2007
35 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
36 now has full SGI RGB image format, including RLE and 16-bit/sample
38 https://rt.cpan.org/Ticket/Display.html?id=8666
40 - logging functions are now available in the API
42 - applied Gabriel Vasseur's patch
43 added documentation, further tests, and support for greyscale images
44 Obviously problems are my fault :)
45 https://rt.cpan.org/Ticket/Display.html?id=28142
47 - the mask for ICO/CUR images is now applied as an alpha channel to
48 the returned image. For the old behaviour, supply ico_masked => 0
49 to read() or read_multi(). This should be less confusing when
50 using Imager as a general image processor.
51 https://rt.cpan.org/Ticket/Display.html?id=29001
55 - in some cases it's possible for giflib/libungif to return color
56 indexes outside the range of colors defined by the image's palette.
57 We now expand the palette to match the indexes used.
58 Thanks to Gabriel Vasseur for reporting this.
60 - fixed various memory leaks that could occur when failing to read png,
61 jpeg, bmp or tga files.
63 - to avoid confusion, channels not present in the image are returned as
64 zero by getscanline(). This has no effect on the C level i_glin()
65 and i_glinf() API functions which continue to not set the unused
68 - the convert() method now returns an image of the same sample size as
70 https://rt.cpan.org/Ticket/Display.html?id=28492
72 - remove repeated text in Imager::Files
73 http://rt.cpan.org/Ticket/Display.html?id=27589
75 - be even more explicit that scale() and friends don't modify the source
76 image, but return a new image.
77 http://rt.cpan.org/Ticket/Display.html?id=28570
79 - improve the error message from errstr() when you try to load a font
80 for which the driver hasn't been built in Imager.
81 http://rt.cpan.org/Ticket/Display.html?id=27571
83 - transparency is now enabled by default when writing GIF images
84 http://rt.cpan.org/Ticket/Display.html?id=27615
86 - Imager would not load on Windows 98
87 http://rt.cpan.org/Ticket/Display.html?id=27653
89 Imager 0.59 - 14 June 2007
94 - fixes a regression introduced by the fixes for RT 11972
95 http://rt.cpan.org/Ticket/Display.html?id=27546
97 - cropping outside the image would return an Imager object with
98 no low-level image object, instead of returning false.
99 Fixed by: Philip Gwyn (Leolo)
100 http://rt.cpan.org/Ticket/Display.html?id=27509
102 Imager 0.58 - 16 May 2007
105 No significant changes from 0.57_01.
107 Imager 0.57_01 - 11 May 2007
110 - added to_rgb16 to produce a 16-bit/sample version of an image
112 - improve freetype 1.x text output efficiency
116 - search another place for rgb.txt, and check all the places
117 Imager::Color checks when deciding whether to skip testing it
118 http://rt.cpan.org/Ticket/Display.html?id=26064
120 - use a convolution kernel size based on the stddev rather than a
121 fixed size when performing a gaussian blur
122 http://rt.cpan.org/Ticket/Display.html?id=25645
124 - document the difference() method's mindist parameter, and debug it.
126 - put the Imager release number in the Inline::C generated code to
127 regenerate Inline code when a new release of Imager is installed.
128 http://rt.cpan.org/Ticket/Display.html?id=26278
130 - fix rendering on alpha channel images for the FreeType 1.x driver.
131 http://rt.cpan.org/Ticket/Display.html?id=11972
133 - fix rendering on alpha channel images for the T1lib driver.
134 http://rt.cpan.org/Ticket/Display.html?id=11972
136 - reworked library probing, we can now set more than one probe
137 function for a library. Disabled the default (non-freetype-config)
138 library probe and added an extra probe function that searches for
139 both ft2build.h and whatever it includes, and adds -I as needed.
140 Hopefully this will fix build problems like

142 http://rt.cpan.org/Ticket/Display.html?id=26086
144 Imager 0.57 - 30 Apr 2007
147 This is a maintenence release fixing a security issue in Imager.
149 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
150 overflow in malloced memory. There will be further discussion of
151 this issue in the ticket below.
152 http://rt.cpan.org/Ticket/Display.html?id=26811
153 CVE-2007-2459 CVE-2007-2413
154 The descriptions at cve.mitre.org varied in quality, please see the
155 ticket at rt.cpan.org for a more accurate description of the issue.
157 Imager 0.56 - 1 Apr 2007
160 - added support for reading 16-bit/sample PGM/PPM images
162 - added support for writing 16-bit/sample PGM/PPM images
164 - improved performance of reading PBM/PGM/PPM images
166 - added support for writing PBM images if the image is paletted and
167 contains only black and white
169 - added a new make_colors value - "mono"
171 - switched from the svn log Changes to a manual Changes to reduce
174 - new sample code - samples/flasher.pl
178 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
179 was returning an image object with an extra reference, this
180 resulted in a memory leak.
181 http://rt.cpan.org/Ticket/Display.html?id=24992
183 - fix rendering on alpha channel images for the FreeType 2.x driver
184 http://rt.cpan.org/Ticket/Display.html?id=11972
186 - reading bmp files now consitently handles short reads. You can now
187 supply a parameter to treat a short read as successful and set
189 http://rt.cpan.org/Ticket/Display.html?id=8426
191 - previously, reading ASCII PBM files required spaces between samples,
192 even though the format doesn't require that
194 - improved documentation of the unsharpmask filter (I hope)
195 http://rt.cpan.org/Ticket/Display.html?id=25531
197 - force flushing of the output from i_tt_dump_names() and test output
198 in t/t35ttfont.t to prevent output from being mixed up.
199 https://rt.cpan.org/Ticket/Display.html?id=24859
201 - rewrite a conditional expression as an if() to hopefully work around
202 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
203 https://rt.cpan.org/Ticket/Display.html?id=25561
205 - avoid Data::Dumper in regops.perl to support older releases of perl
206 https://rt.cpan.org/Ticket/Display.html?id=24391
208 Imager 0.55 - 16 Dec 2006
211 This is primarily a bug fix release.
213 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
215 There is one new feature:
217 - the Win32 font driver now supports UTF8 (RT 22166)
218 http://www.cpanforum.com/threads/3276
219 http://rt.cpan.org/Ticket/Display.html?id=22166
221 Several bugs were fixed:
223 - the string() method would not output the string "0"
224 http://rt.cpan.org/Public/Bug/Display.html?id=21770
226 - fills.c was failing to compile on Solaris 10 (compiler unknown)
227 http://rt.cpan.org/Public/Bug/Display.html?id=21944
229 - the gif_disposal and gif_user_input tags weren't being read from
231 http://rt.cpan.org/Public/Bug/Display.html?id=22192
233 - gif.c was failing to build under MSVC
234 http://rt.cpan.org/Ticket/Display.html?id=23922
236 - in some cases strings passed to the string() method were treated as
237 terminated by NUL (chr 0)
238 http://rt.cpan.org/Public/Bug/Display.html?id=21770
240 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
241 that's the default build name for zlib on Win32.
242 http://rt.cpan.org/Ticket/Display.html?id=23064
244 - search $Config{incpath} for headers too, which we should have been
247 Win32 font driver fixes:
249 - the global descent value from bounding box was the wrong sign
250 http://www.cpanforum.com/threads/3276
252 - if the first or last glyph overflowed the left or right side of the
253 advance width they would be clipped
256 Imager 0.54 - 14 Sep 2006
259 This is primarily a feature release:
261 - a new qtype value 'mixing' has been added to the scale()
262 method. This is faster than 'normal', slower than 'preview'. This
263 is based on the method used by pnmscale, and seems to produce less
264 blurry results than normal.
265 http://rt.cpan.org/Public/Bug/Display.html?id=20677
267 - the rubthrough() method can now render onto images with an alpha
269 http://rt.cpan.org/Ticket/Display.html?id=20678
271 - the read_multi() method now falls back to calling doing a single
272 image read via the read() method and write_multi() will now fall
273 back to calling write() if a single image is supplied. This means
274 you can simply call the read_multi() or write_multi() functions
275 without having to check if the type is formatted by that method.
276 http://rt.cpan.org/Ticket/Display.html?id=19457
277 http://rt.cpan.org/Ticket/Display.html?id=19458
279 - the GIF loop extension can now be written. If you don't have
280 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
282 http://rt.cpan.org/Ticket/Display.html?id=21185
284 - getscanline() and setscanline() can now read/write palette index
285 based data from/to the image for paletted images, by setting type to
287 http://rt.cpan.org/Ticket/Display.html?id=20338
289 - we no longer hassle you to disable GIF support
290 http://rt.cpan.org/Ticket/Display.html?id=20687
292 - minor documentation fixes
295 Imager 0.53 - 26 Jul 2006
298 This is a bugfix release.
300 Some test code was left in a code path not covered by the test
301 suite. A test was added to cover this code path and the test code was
303 http://rt.cpan.org/Public/Bug/Display.html?id=20705
306 Imager 0.52 - 25 Jul 2006
309 This is primarily a feature release, but contains a fair few bug
312 - ability to read and write MS Windows ICO and CUR files
314 - you can now add file format plugins to support new file formats
316 - add POD coverage tests
318 - setcolors() and addcolors() now accept color names and so on
319 instead of requiring Imager::Color objects.
320 http://rt.cpan.org/Ticket/Display.html?id=20056
322 - flood_fill() can now fill to a specified border color instead of
323 just to the area the same color as the seed.
324 http://rt.cpan.org/Ticket/Display.html?id=19618
329 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
330 calculating the advance width.
331 http://rt.cpan.org/Public/Bug/Display.html?id=20554
333 - bounding_box for the T1 driver wasn't including leading and
334 trailing spaces in the bounding box as the other drivers did, it also
335 produced strange results for empty strings or strings containing only
338 - when reading CMYK jpeg images they were being transferred to the
339 image object as is, producing a four channel image. It only looked ok
340 due to an old still unfixed Photoshop bug. We now convert from the
341 inverted CMYK that photoshop (and Corel for example) produce into RGB.
342 http://rt.cpan.org/Ticket/Display.html?id=20416
344 - reading a CYMK TIFF would result in a 4 channel image, reading any
345 image with more than 4 channels (eg. RGB with 2 alpha channels) would
347 http://rt.cpan.org/Ticket/Display.html?id=20415
349 - added /usr/local/include to the default include search path, since
350 we were already searching /usr/local/lib for libraries.
352 And various minor fixes and documentation updates.
355 Imager 0.51 - 23 Apr 2006
358 - fix a validation bug when processing JPEG EXIF data that can cause
360 http://rt.cpan.org/Public/Bug/Display.html?id=18496
362 - fix mis-processing of the src_maxx and src_maxy parameters of the
364 http://rt.cpan.org/Public/Bug/Display.html?id=18712
366 - fix a problem in Imager's "smart" handling of the color parameter
368 http://rt.cpan.org/Public/Bug/Display.html?id=18561
371 Imager 0.50 - 29 Mar 2006
374 - CRITICAL: fixes a segmentation fault from attempting to write a 2
375 or 4 channel image to jpeg or a 2 channel image to tga where the
376 output is an in-memeory buffer.
377 http://rt.cpan.org/Public/Bug/Display.html?id=18397
379 - fixes an incorrect pointer parameter in the PNG code
380 http://rt.cpan.org/Public/Bug/Display.html?id=18051
382 - skip Inline::C tests when building in a directory with spaces
383 http://rt.cpan.org/Public/Bug/Display.html?id=18049
