47 library probe and added an extra probe function that searches for
48 both ft2build.h and whatever it includes, and adds -I as needed.
49 Hopefully this will fix build problems like

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