1 Imager release history. Older releases can be found in Changes.old
8 - in some cases it's possible for giflib/libungif to return color
9 indexes outside the range of colors defined by the image's palette.
10 We now expand the palette to match the indexes used.
11 Thanks to Gabriel Vasseur for reporting this.
13 - fixed various memory leaks that could occur when failing to read png,
14 jpeg, bmp or tga files.
16 - to avoid confusion, channels not present in the image are returned as
17 zero by getscanline(). This has no effect on the C level i_glin()
18 and i_glinf() API functions which continue to not set the unused
21 Imager 0.59 - 14 June 2007
26 - fixes a regression introduced by the fixes for RT 11972
27 http://rt.cpan.org/Ticket/Display.html?id=27546
29 - cropping outside the image would return an Imager object with
30 no low-level image object, instead of returning false.
31 Fixed by: Philip Gwyn (Leolo)
32 http://rt.cpan.org/Ticket/Display.html?id=27509
34 Imager 0.58 - 16 May 2007
37 No significant changes from 0.57_01.
39 Imager 0.57_01 - 11 May 2007
42 - added to_rgb16 to produce a 16-bit/sample version of an image
44 - improve freetype 1.x text output efficiency
48 - search another place for rgb.txt, and check all the places
49 Imager::Color checks when deciding whether to skip testing it
50 http://rt.cpan.org/Ticket/Display.html?id=26064
52 - use a convolution kernel size based on the stddev rather than a
53 fixed size when performing a gaussian blur
54 http://rt.cpan.org/Ticket/Display.html?id=25645
56 - document the difference() method's mindist parameter, and debug it.
58 - put the Imager release number in the Inline::C generated code to
59 regenerate Inline code when a new release of Imager is installed.
60 http://rt.cpan.org/Ticket/Display.html?id=26278
62 - fix rendering on alpha channel images for the FreeType 1.x driver.
63 http://rt.cpan.org/Ticket/Display.html?id=11972
65 - fix rendering on alpha channel images for the T1lib driver.
66 http://rt.cpan.org/Ticket/Display.html?id=11972
68 - reworked library probing, we can now set more than one probe
69 function for a library. Disabled the default (non-freetype-config)
70 library probe and added an extra probe function that searches for
71 both ft2build.h and whatever it includes, and adds -I as needed.
72 Hopefully this will fix build problems like

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