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 - the SGI RLE compression code could overflow its compression buffer
37 http://rt.cpan.org/Ticket/Display.html?id=30334
39 - the 32-bit output function used by the SGI code only handled values
40 under 0x10000. This was most noticable when writing large RLE images.
41 http://rt.cpan.org/Ticket/Display.html?id=30335
43 - validate chan_count for chans == NULL for each of the i_gsamp()
45 http://rt.cpan.org/Ticket/Display.html?id=28985
47 - attempt to work around the test failure at
48 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
49 http://rt.cpan.org/Ticket/Display.html?id=29562
51 Imager 0.60 - 30 August 2007
54 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
55 now has full SGI RGB image format, including RLE and 16-bit/sample
57 https://rt.cpan.org/Ticket/Display.html?id=8666
59 - logging functions are now available in the API
61 - applied Gabriel Vasseur's patch
62 added documentation, further tests, and support for greyscale images
63 Obviously problems are my fault :)
64 https://rt.cpan.org/Ticket/Display.html?id=28142
66 - the mask for ICO/CUR images is now applied as an alpha channel to
67 the returned image. For the old behaviour, supply ico_masked => 0
68 to read() or read_multi(). This should be less confusing when
69 using Imager as a general image processor.
70 https://rt.cpan.org/Ticket/Display.html?id=29001
74 - in some cases it's possible for giflib/libungif to return color
75 indexes outside the range of colors defined by the image's palette.
76 We now expand the palette to match the indexes used.
77 Thanks to Gabriel Vasseur for reporting this.
79 - fixed various memory leaks that could occur when failing to read png,
80 jpeg, bmp or tga files.
82 - to avoid confusion, channels not present in the image are returned as
83 zero by getscanline(). This has no effect on the C level i_glin()
84 and i_glinf() API functions which continue to not set the unused
87 - the convert() method now returns an image of the same sample size as
89 https://rt.cpan.org/Ticket/Display.html?id=28492
91 - remove repeated text in Imager::Files
92 http://rt.cpan.org/Ticket/Display.html?id=27589
94 - be even more explicit that scale() and friends don't modify the source
95 image, but return a new image.
96 http://rt.cpan.org/Ticket/Display.html?id=28570
98 - improve the error message from errstr() when you try to load a font
99 for which the driver hasn't been built in Imager.
100 http://rt.cpan.org/Ticket/Display.html?id=27571
102 - transparency is now enabled by default when writing GIF images
103 http://rt.cpan.org/Ticket/Display.html?id=27615
105 - Imager would not load on Windows 98
106 http://rt.cpan.org/Ticket/Display.html?id=27653
108 Imager 0.59 - 14 June 2007
113 - fixes a regression introduced by the fixes for RT 11972
114 http://rt.cpan.org/Ticket/Display.html?id=27546
116 - cropping outside the image would return an Imager object with
117 no low-level image object, instead of returning false.
118 Fixed by: Philip Gwyn (Leolo)
119 http://rt.cpan.org/Ticket/Display.html?id=27509
121 Imager 0.58 - 16 May 2007
124 No significant changes from 0.57_01.
126 Imager 0.57_01 - 11 May 2007
129 - added to_rgb16 to produce a 16-bit/sample version of an image
131 - improve freetype 1.x text output efficiency
135 - search another place for rgb.txt, and check all the places
136 Imager::Color checks when deciding whether to skip testing it
137 http://rt.cpan.org/Ticket/Display.html?id=26064
139 - use a convolution kernel size based on the stddev rather than a
140 fixed size when performing a gaussian blur
141 http://rt.cpan.org/Ticket/Display.html?id=25645
143 - document the difference() method's mindist parameter, and debug it.
145 - put the Imager release number in the Inline::C generated code to
146 regenerate Inline code when a new release of Imager is installed.
147 http://rt.cpan.org/Ticket/Display.html?id=26278
149 - fix rendering on alpha channel images for the FreeType 1.x driver.
150 http://rt.cpan.org/Ticket/Display.html?id=11972
152 - fix rendering on alpha channel images for the T1lib driver.
153 http://rt.cpan.org/Ticket/Display.html?id=11972
155 - reworked library probing, we can now set more than one probe
156 function for a library. Disabled the default (non-freetype-config)
157 library probe and added an extra probe function that searches for
158 both ft2build.h and whatever it includes, and adds -I as needed.
159 Hopefully this will fix build problems like
160 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
161 http://rt.cpan.org/Ticket/Display.html?id=26086
163 Imager 0.57 - 30 Apr 2007
166 This is a maintenence release fixing a security issue in Imager.
168 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
169 overflow in malloced memory. There will be further discussion of
170 this issue in the ticket below.
171 http://rt.cpan.org/Ticket/Display.html?id=26811
172 CVE-2007-2459 CVE-2007-2413
173 The descriptions at cve.mitre.org varied in quality, please see the
174 ticket at rt.cpan.org for a more accurate description of the issue.
176 Imager 0.56 - 1 Apr 2007
179 - added support for reading 16-bit/sample PGM/PPM images
181 - added support for writing 16-bit/sample PGM/PPM images
183 - improved performance of reading PBM/PGM/PPM images
185 - added support for writing PBM images if the image is paletted and
186 contains only black and white
188 - added a new make_colors value - "mono"
190 - switched from the svn log Changes to a manual Changes to reduce
193 - new sample code - samples/flasher.pl
197 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
198 was returning an image object with an extra reference, this
199 resulted in a memory leak.
200 http://rt.cpan.org/Ticket/Display.html?id=24992
202 - fix rendering on alpha channel images for the FreeType 2.x driver
203 http://rt.cpan.org/Ticket/Display.html?id=11972
205 - reading bmp files now consitently handles short reads. You can now
206 supply a parameter to treat a short read as successful and set
208 http://rt.cpan.org/Ticket/Display.html?id=8426
210 - previously, reading ASCII PBM files required spaces between samples,
211 even though the format doesn't require that
213 - improved documentation of the unsharpmask filter (I hope)
214 http://rt.cpan.org/Ticket/Display.html?id=25531
216 - force flushing of the output from i_tt_dump_names() and test output
217 in t/t35ttfont.t to prevent output from being mixed up.
218 https://rt.cpan.org/Ticket/Display.html?id=24859
220 - rewrite a conditional expression as an if() to hopefully work around
221 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
222 https://rt.cpan.org/Ticket/Display.html?id=25561
224 - avoid Data::Dumper in regops.perl to support older releases of perl
225 https://rt.cpan.org/Ticket/Display.html?id=24391
227 Imager 0.55 - 16 Dec 2006
230 This is primarily a bug fix release.
232 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
234 There is one new feature:
236 - the Win32 font driver now supports UTF8 (RT 22166)
237 http://www.cpanforum.com/threads/3276
238 http://rt.cpan.org/Ticket/Display.html?id=22166
240 Several bugs were fixed:
242 - the string() method would not output the string "0"
243 http://rt.cpan.org/Public/Bug/Display.html?id=21770
245 - fills.c was failing to compile on Solaris 10 (compiler unknown)
246 http://rt.cpan.org/Public/Bug/Display.html?id=21944
248 - the gif_disposal and gif_user_input tags weren't being read from
250 http://rt.cpan.org/Public/Bug/Display.html?id=22192
252 - gif.c was failing to build under MSVC
253 http://rt.cpan.org/Ticket/Display.html?id=23922
255 - in some cases strings passed to the string() method were treated as
256 terminated by NUL (chr 0)
257 http://rt.cpan.org/Public/Bug/Display.html?id=21770
259 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
260 that's the default build name for zlib on Win32.
261 http://rt.cpan.org/Ticket/Display.html?id=23064
263 - search $Config{incpath} for headers too, which we should have been
266 Win32 font driver fixes:
268 - the global descent value from bounding box was the wrong sign
269 http://www.cpanforum.com/threads/3276
271 - if the first or last glyph overflowed the left or right side of the
272 advance width they would be clipped
275 Imager 0.54 - 14 Sep 2006
278 This is primarily a feature release:
280 - a new qtype value 'mixing' has been added to the scale()
281 method. This is faster than 'normal', slower than 'preview'. This
282 is based on the method used by pnmscale, and seems to produce less
283 blurry results than normal.
284 http://rt.cpan.org/Public/Bug/Display.html?id=20677
286 - the rubthrough() method can now render onto images with an alpha
288 http://rt.cpan.org/Ticket/Display.html?id=20678
290 - the read_multi() method now falls back to calling doing a single
291 image read via the read() method and write_multi() will now fall
292 back to calling write() if a single image is supplied. This means
293 you can simply call the read_multi() or write_multi() functions
294 without having to check if the type is formatted by that method.
295 http://rt.cpan.org/Ticket/Display.html?id=19457
296 http://rt.cpan.org/Ticket/Display.html?id=19458
298 - the GIF loop extension can now be written. If you don't have
299 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
301 http://rt.cpan.org/Ticket/Display.html?id=21185
303 - getscanline() and setscanline() can now read/write palette index
304 based data from/to the image for paletted images, by setting type to
306 http://rt.cpan.org/Ticket/Display.html?id=20338
308 - we no longer hassle you to disable GIF support
309 http://rt.cpan.org/Ticket/Display.html?id=20687
311 - minor documentation fixes
314 Imager 0.53 - 26 Jul 2006
317 This is a bugfix release.
319 Some test code was left in a code path not covered by the test
320 suite. A test was added to cover this code path and the test code was
322 http://rt.cpan.org/Public/Bug/Display.html?id=20705
325 Imager 0.52 - 25 Jul 2006
328 This is primarily a feature release, but contains a fair few bug
331 - ability to read and write MS Windows ICO and CUR files
333 - you can now add file format plugins to support new file formats
335 - add POD coverage tests
337 - setcolors() and addcolors() now accept color names and so on
338 instead of requiring Imager::Color objects.
339 http://rt.cpan.org/Ticket/Display.html?id=20056
341 - flood_fill() can now fill to a specified border color instead of
342 just to the area the same color as the seed.
343 http://rt.cpan.org/Ticket/Display.html?id=19618
348 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
349 calculating the advance width.
350 http://rt.cpan.org/Public/Bug/Display.html?id=20554
352 - bounding_box for the T1 driver wasn't including leading and
353 trailing spaces in the bounding box as the other drivers did, it also
354 produced strange results for empty strings or strings containing only
357 - when reading CMYK jpeg images they were being transferred to the
358 image object as is, producing a four channel image. It only looked ok
359 due to an old still unfixed Photoshop bug. We now convert from the
360 inverted CMYK that photoshop (and Corel for example) produce into RGB.
361 http://rt.cpan.org/Ticket/Display.html?id=20416
363 - reading a CYMK TIFF would result in a 4 channel image, reading any
364 image with more than 4 channels (eg. RGB with 2 alpha channels) would
366 http://rt.cpan.org/Ticket/Display.html?id=20415
368 - added /usr/local/include to the default include search path, since
369 we were already searching /usr/local/lib for libraries.
371 And various minor fixes and documentation updates.
374 Imager 0.51 - 23 Apr 2006
377 - fix a validation bug when processing JPEG EXIF data that can cause
379 http://rt.cpan.org/Public/Bug/Display.html?id=18496
381 - fix mis-processing of the src_maxx and src_maxy parameters of the
383 http://rt.cpan.org/Public/Bug/Display.html?id=18712
385 - fix a problem in Imager's "smart" handling of the color parameter
387 http://rt.cpan.org/Public/Bug/Display.html?id=18561
390 Imager 0.50 - 29 Mar 2006
393 - CRITICAL: fixes a segmentation fault from attempting to write a 2
394 or 4 channel image to jpeg or a 2 channel image to tga where the
395 output is an in-memeory buffer.
396 http://rt.cpan.org/Public/Bug/Display.html?id=18397
398 - fixes an incorrect pointer parameter in the PNG code
399 http://rt.cpan.org/Public/Bug/Display.html?id=18051
401 - skip Inline::C tests when building in a directory with spaces
402 http://rt.cpan.org/Public/Bug/Display.html?id=18049
