8 - samples/gifscale.pl sourced the base value for gif_top from
10 Thanks to Eleneldil G. Arilou for pointing this out.
12 - t/t82inline.t no longer loads B at runtime, to work around a bug
13 in some 5.005_0[45] installations.
14 http://rt.cpan.org/Ticket/Display.html?id=30508
16 - work around Module::Depends::Intrusive bug #21229

22 - the hardinvert filter now supports large samples
24 Imager 0.61_02 - 28 November 2007
27 - major TIFF support re-work
28 http://rt.cpan.org/Ticket/Display.html?id=20329
30 - added a C level image interface for accessing samples from 1-32
31 bits, exposed this at the perl level in getsamples()
33 - the conv filter now works at floating point precision for high bit
36 - added is_bilevel method to test whether an image should be written as

54 Thanks to Slaven Rezic.
55 http://rt.cpan.org/Ticket/Display.html?id=30889
57 - on some perl's the infix expression parser test would fail due to
58 actions in the grammar returning false. Made sure all actions return
60 Thanks to Richard Fairhurst for spending a lot of time in tracking
62 http://rt.cpan.org/Public/Bug/Display.html?id=29562
64 Imager 0.61 - 5 November 2007
67 - added samples/gifscale.pl, which adjusts the screen size/position tags
68 when scaling an animated gif
69 http://rt.cpan.org/Ticket/Display.html?id=27591
73 - correct handling of sz in matrix_transform() - this should allow
74 perspective type transformations to work now.
75 http://rt.cpan.org/Ticket/Display.html?id=29936
77 - prevent a cast to integer warning on x64 builds in datatypes.c
78 also fixed some other type warnings
79 https://rt.cpan.org/Ticket/Display.html?id=30204
81 - some sub-directory tests depended on files produced by the parent
83 http://rt.cpan.org/Ticket/Display.html?id=30203
85 - Imager::Font::Wrap doesn't correctly set savepos
86 thanks to Nikita Dedik and Eleneldil G. Arilou for reporting this.
87 http://rt.cpan.org/Ticket/Display.html?id=29771
89 - test 171 in t/t01introvert.t was failing on perls configured to
91 http://rt.cpan.org/Ticket/Display.html?id=29413
93 - the code for the transform2() uminus operator was missing a break.
94 Added tests for better code coverage of the ops.
95 http://rt.cpan.org/Ticket/Display.html?id=29296
97 - the SGI RLE compression code could overflow its compression buffer
98 http://rt.cpan.org/Ticket/Display.html?id=30334
100 - the 32-bit output function used by the SGI code only handled values
101 under 0x10000. This was most noticable when writing large RLE images.
102 http://rt.cpan.org/Ticket/Display.html?id=30335
104 - validate chan_count for chans == NULL for each of the i_gsamp()
106 http://rt.cpan.org/Ticket/Display.html?id=28985
108 - attempt to work around the test failure at
109 http://www.nntp.perl.org/group/perl.cpan.testers/2007/09/msg650810.html
110 http://rt.cpan.org/Ticket/Display.html?id=29562
112 - improve the error messages produced when attempting to read or write
113 an unknown image file format.
114 http://rt.cpan.org/Ticket/Display.html?id=30103
116 - improve the transform2() documentation
117 http://rt.cpan.org/Ticket/Display.html?id=29267
119 - correctly generate the author key in META.yml
120 http://rt.cpan.org/Ticket/Display.html?id=30377
122 - correctly blend a rotated (or matrix_transformed()) image when
123 performing interpolation in the presence of an alpha channel.
124 Also corrected the centring of the rotated image on the output
127 Imager 0.60 - 30 August 2007
130 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
131 now has full SGI RGB image format, including RLE and 16-bit/sample
133 https://rt.cpan.org/Ticket/Display.html?id=8666
135 - logging functions are now available in the API
137 - applied Gabriel Vasseur's patch
138 added documentation, further tests, and support for greyscale images
139 Obviously problems are my fault :)
140 https://rt.cpan.org/Ticket/Display.html?id=28142
142 - the mask for ICO/CUR images is now applied as an alpha channel to
143 the returned image. For the old behaviour, supply ico_masked => 0
144 to read() or read_multi(). This should be less confusing when
145 using Imager as a general image processor.
146 https://rt.cpan.org/Ticket/Display.html?id=29001
150 - in some cases it's possible for giflib/libungif to return color
151 indexes outside the range of colors defined by the image's palette.
152 We now expand the palette to match the indexes used.
153 Thanks to Gabriel Vasseur for reporting this.
155 - fixed various memory leaks that could occur when failing to read png,
156 jpeg, bmp or tga files.
158 - to avoid confusion, channels not present in the image are returned as
159 zero by getscanline(). This has no effect on the C level i_glin()
160 and i_glinf() API functions which continue to not set the unused
163 - the convert() method now returns an image of the same sample size as
165 https://rt.cpan.org/Ticket/Display.html?id=28492
167 - remove repeated text in Imager::Files
168 http://rt.cpan.org/Ticket/Display.html?id=27589
170 - be even more explicit that scale() and friends don't modify the source
171 image, but return a new image.
172 http://rt.cpan.org/Ticket/Display.html?id=28570
174 - improve the error message from errstr() when you try to load a font
175 for which the driver hasn't been built in Imager.
176 http://rt.cpan.org/Ticket/Display.html?id=27571
178 - transparency is now enabled by default when writing GIF images
179 http://rt.cpan.org/Ticket/Display.html?id=27615
181 - Imager would not load on Windows 98
182 http://rt.cpan.org/Ticket/Display.html?id=27653
184 Imager 0.59 - 14 June 2007
189 - fixes a regression introduced by the fixes for RT 11972
190 http://rt.cpan.org/Ticket/Display.html?id=27546
192 - cropping outside the image would return an Imager object with
193 no low-level image object, instead of returning false.
194 Fixed by: Philip Gwyn (Leolo)
195 http://rt.cpan.org/Ticket/Display.html?id=27509
197 Imager 0.58 - 16 May 2007
200 No significant changes from 0.57_01.
202 Imager 0.57_01 - 11 May 2007
205 - added to_rgb16 to produce a 16-bit/sample version of an image
207 - improve freetype 1.x text output efficiency
211 - search another place for rgb.txt, and check all the places
212 Imager::Color checks when deciding whether to skip testing it
213 http://rt.cpan.org/Ticket/Display.html?id=26064
215 - use a convolution kernel size based on the stddev rather than a
216 fixed size when performing a gaussian blur
217 http://rt.cpan.org/Ticket/Display.html?id=25645
219 - document the difference() method's mindist parameter, and debug it.
221 - put the Imager release number in the Inline::C generated code to
222 regenerate Inline code when a new release of Imager is installed.
223 http://rt.cpan.org/Ticket/Display.html?id=26278
225 - fix rendering on alpha channel images for the FreeType 1.x driver.
226 http://rt.cpan.org/Ticket/Display.html?id=11972
228 - fix rendering on alpha channel images for the T1lib driver.
229 http://rt.cpan.org/Ticket/Display.html?id=11972
231 - reworked library probing, we can now set more than one probe
232 function for a library. Disabled the default (non-freetype-config)
233 library probe and added an extra probe function that searches for
234 both ft2build.h and whatever it includes, and adds -I as needed.
235 Hopefully this will fix build problems like
236 http://www.nntp.perl.org/group/perl.cpan.testers/2007/05/msg472281.html
237 http://rt.cpan.org/Ticket/Display.html?id=26086
239 Imager 0.57 - 30 Apr 2007
242 This is a maintenence release fixing a security issue in Imager.
244 - CRITICAL: a specially crafted compressed BMP file can cause a buffer
245 overflow in malloced memory. There will be further discussion of
246 this issue in the ticket below.
247 http://rt.cpan.org/Ticket/Display.html?id=26811
248 CVE-2007-2459 CVE-2007-2413
249 The descriptions at cve.mitre.org varied in quality, please see the
250 ticket at rt.cpan.org for a more accurate description of the issue.
252 Imager 0.56 - 1 Apr 2007
255 - added support for reading 16-bit/sample PGM/PPM images
257 - added support for writing 16-bit/sample PGM/PPM images
259 - improved performance of reading PBM/PGM/PPM images
261 - added support for writing PBM images if the image is paletted and
262 contains only black and white
264 - added a new make_colors value - "mono"
266 - switched from the svn log Changes to a manual Changes to reduce
269 - new sample code - samples/flasher.pl
273 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
274 was returning an image object with an extra reference, this
275 resulted in a memory leak.
276 http://rt.cpan.org/Ticket/Display.html?id=24992
278 - fix rendering on alpha channel images for the FreeType 2.x driver
279 http://rt.cpan.org/Ticket/Display.html?id=11972
281 - reading bmp files now consitently handles short reads. You can now
282 supply a parameter to treat a short read as successful and set
284 http://rt.cpan.org/Ticket/Display.html?id=8426
286 - previously, reading ASCII PBM files required spaces between samples,
287 even though the format doesn't require that
289 - improved documentation of the unsharpmask filter (I hope)
290 http://rt.cpan.org/Ticket/Display.html?id=25531
292 - force flushing of the output from i_tt_dump_names() and test output
293 in t/t35ttfont.t to prevent output from being mixed up.
294 https://rt.cpan.org/Ticket/Display.html?id=24859
296 - rewrite a conditional expression as an if() to hopefully work around
297 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
298 https://rt.cpan.org/Ticket/Display.html?id=25561
300 - avoid Data::Dumper in regops.perl to support older releases of perl
301 https://rt.cpan.org/Ticket/Display.html?id=24391
303 Imager 0.55 - 16 Dec 2006
306 This is primarily a bug fix release.
308 Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
310 There is one new feature:
312 - the Win32 font driver now supports UTF8 (RT 22166)
313 http://www.cpanforum.com/threads/3276
314 http://rt.cpan.org/Ticket/Display.html?id=22166
316 Several bugs were fixed:
318 - the string() method would not output the string "0"
319 http://rt.cpan.org/Public/Bug/Display.html?id=21770
321 - fills.c was failing to compile on Solaris 10 (compiler unknown)
322 http://rt.cpan.org/Public/Bug/Display.html?id=21944
324 - the gif_disposal and gif_user_input tags weren't being read from
326 http://rt.cpan.org/Public/Bug/Display.html?id=22192
328 - gif.c was failing to build under MSVC
329 http://rt.cpan.org/Ticket/Display.html?id=23922
331 - in some cases strings passed to the string() method were treated as
332 terminated by NUL (chr 0)
333 http://rt.cpan.org/Public/Bug/Display.html?id=21770
335 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
336 that's the default build name for zlib on Win32.
337 http://rt.cpan.org/Ticket/Display.html?id=23064
339 - search $Config{incpath} for headers too, which we should have been
342 Win32 font driver fixes:
344 - the global descent value from bounding box was the wrong sign
345 http://www.cpanforum.com/threads/3276
347 - if the first or last glyph overflowed the left or right side of the
348 advance width they would be clipped
351 Imager 0.54 - 14 Sep 2006
354 This is primarily a feature release:
356 - a new qtype value 'mixing' has been added to the scale()
357 method. This is faster than 'normal', slower than 'preview'. This
358 is based on the method used by pnmscale, and seems to produce less
359 blurry results than normal.
360 http://rt.cpan.org/Public/Bug/Display.html?id=20677
362 - the rubthrough() method can now render onto images with an alpha
364 http://rt.cpan.org/Ticket/Display.html?id=20678
366 - the read_multi() method now falls back to calling doing a single
367 image read via the read() method and write_multi() will now fall
368 back to calling write() if a single image is supplied. This means
369 you can simply call the read_multi() or write_multi() functions
370 without having to check if the type is formatted by that method.
371 http://rt.cpan.org/Ticket/Display.html?id=19457
372 http://rt.cpan.org/Ticket/Display.html?id=19458
374 - the GIF loop extension can now be written. If you don't have
375 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
377 http://rt.cpan.org/Ticket/Display.html?id=21185
379 - getscanline() and setscanline() can now read/write palette index
380 based data from/to the image for paletted images, by setting type to
382 http://rt.cpan.org/Ticket/Display.html?id=20338
384 - we no longer hassle you to disable GIF support
385 http://rt.cpan.org/Ticket/Display.html?id=20687
387 - minor documentation fixes
390 Imager 0.53 - 26 Jul 2006
393 This is a bugfix release.
395 Some test code was left in a code path not covered by the test
396 suite. A test was added to cover this code path and the test code was
398 http://rt.cpan.org/Public/Bug/Display.html?id=20705
401 Imager 0.52 - 25 Jul 2006
404 This is primarily a feature release, but contains a fair few bug
407 - ability to read and write MS Windows ICO and CUR files
409 - you can now add file format plugins to support new file formats
411 - add POD coverage tests
413 - setcolors() and addcolors() now accept color names and so on
414 instead of requiring Imager::Color objects.
415 http://rt.cpan.org/Ticket/Display.html?id=20056
417 - flood_fill() can now fill to a specified border color instead of
418 just to the area the same color as the seed.
419 http://rt.cpan.org/Ticket/Display.html?id=19618
424 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
425 calculating the advance width.
426 http://rt.cpan.org/Public/Bug/Display.html?id=20554
428 - bounding_box for the T1 driver wasn't including leading and
429 trailing spaces in the bounding box as the other drivers did, it also
430 produced strange results for empty strings or strings containing only
433 - when reading CMYK jpeg images they were being transferred to the
434 image object as is, producing a four channel image. It only looked ok
435 due to an old still unfixed Photoshop bug. We now convert from the
436 inverted CMYK that photoshop (and Corel for example) produce into RGB.
437 http://rt.cpan.org/Ticket/Display.html?id=20416
439 - reading a CYMK TIFF would result in a 4 channel image, reading any
440 image with more than 4 channels (eg. RGB with 2 alpha channels) would
442 http://rt.cpan.org/Ticket/Display.html?id=20415
444 - added /usr/local/include to the default include search path, since
445 we were already searching /usr/local/lib for libraries.
447 And various minor fixes and documentation updates.
450 Imager 0.51 - 23 Apr 2006
453 - fix a validation bug when processing JPEG EXIF data that can cause
455 http://rt.cpan.org/Public/Bug/Display.html?id=18496
457 - fix mis-processing of the src_maxx and src_maxy parameters of the
459 http://rt.cpan.org/Public/Bug/Display.html?id=18712
461 - fix a problem in Imager's "smart" handling of the color parameter
463 http://rt.cpan.org/Public/Bug/Display.html?id=18561
466 Imager 0.50 - 29 Mar 2006
469 - CRITICAL: fixes a segmentation fault from attempting to write a 2
470 or 4 channel image to jpeg or a 2 channel image to tga where the
471 output is an in-memeory buffer.
472 http://rt.cpan.org/Public/Bug/Display.html?id=18397
474 - fixes an incorrect pointer parameter in the PNG code
475 http://rt.cpan.org/Public/Bug/Display.html?id=18051
477 - skip Inline::C tests when building in a directory with spaces
478 http://rt.cpan.org/Public/Bug/Display.html?id=18049
