1 Imager release history. Older releases can be found in Changes.old
6 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
7 now has full SGI RGB image format, including RLE and 16-bit/sample
9 https://rt.cpan.org/Ticket/Display.html?id=8666
11 - logging functions are now available in the API
15 - in some cases it's possible for giflib/libungif to return color
16 indexes outside the range of colors defined by the image's palette.
17 We now expand the palette to match the indexes used.
18 Thanks to Gabriel Vasseur for reporting this.
20 - fixed various memory leaks that could occur when failing to read png,
21 jpeg, bmp or tga files.
23 - to avoid confusion, channels not present in the image are returned as
24 zero by getscanline(). This has no effect on the C level i_glin()
25 and i_glinf() API functions which continue to not set the unused
28 - the convert() method now returns an image of the same sample size as
30 https://rt.cpan.org/Ticket/Display.html?id=28492
32 - remove repeated text in Imager::Files
33 http://rt.cpan.org/Ticket/Display.html?id=27589
35 - be even more explicit that scale() and friends don't modify the source
36 image, but return a new image.
37 http://rt.cpan.org/Ticket/Display.html?id=28570
39 Imager 0.59 - 14 June 2007
44 - fixes a regression introduced by the fixes for RT 11972
45 http://rt.cpan.org/Ticket/Display.html?id=27546
47 - cropping outside the image would return an Imager object with
48 no low-level image object, instead of returning false.
49 Fixed by: Philip Gwyn (Leolo)
50 http://rt.cpan.org/Ticket/Display.html?id=27509
52 Imager 0.58 - 16 May 2007
55 No significant changes from 0.57_01.
57 Imager 0.57_01 - 11 May 2007
60 - added to_rgb16 to produce a 16-bit/sample version of an image
62 - improve freetype 1.x text output efficiency
66 - search another place for rgb.txt, and check all the places
67 Imager::Color checks when deciding whether to skip testing it
68 http://rt.cpan.org/Ticket/Display.html?id=26064
70 - use a convolution kernel size based on the stddev rather than a
71 fixed size when performing a gaussian blur
72 http://rt.cpan.org/Ticket/Display.html?id=25645
74 - document the difference() method's mindist parameter, and debug it.
76 - put the Imager release number in the Inline::C generated code to
77 regenerate Inline code when a new release of Imager is installed.
78 http://rt.cpan.org/Ticket/Display.html?id=26278
80 - fix rendering on alpha channel images for the FreeType 1.x driver.
81 http://rt.cpan.org/Ticket/Display.html?id=11972
83 - fix rendering on alpha channel images for the T1lib driver.
84 http://rt.cpan.org/Ticket/Display.html?id=11972
86 - reworked library probing, we can now set more than one probe
87 function for a library. Disabled the default (non-freetype-config)
88 library probe and added an extra probe function that searches for
89 both ft2build.h and whatever it includes, and adds -I as needed.
90 Hopefully this will fix build problems like

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