1791cbdb
TC
3Coverity finally finished a build, fix a few problems:
4
8445279e
TC
5High severity:
6
1791cbdb 7 - reading a color-mapped TGA file with an id string would cause a
8445279e 8 double-free if the palette was truncated. CID 185317.
1791cbdb 9
6494c395
TC
10 - mixing scaling to sizes where the accumulator row, the working
11 output row or the working input row didn't fit into the address
12 space could result in memory leaks. This can probably only be
8445279e 13 reproduced on very wide floating-point sample images. CID 185318.
6494c395 14
fc24ca5f 15 - convert an array style function parameter pointer to pointer style
3d7b055c 16 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 17 CID 185343.
3d7b055c 18
8445279e 19 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 20
20c297d4 21 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 22 implementation. CID 185303.
20c297d4 23
fc24ca5f 24 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 25 drawing (it should always end up being set.) CID 185341.
fc24ca5f 26
f7675b46 27 - addi style makemap could potentially read one past the end of an
8445279e 28 array. CID 185337.
f7675b46 29
58ec1fde
TC
30 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
31 would result in read beyond the end of the built-in hatch array.
32 Negative values (which Coverity didn't complain about) could also
8445279e 33 cause problems. CID 185331.
58ec1fde 34
b7346865
TC
35 - the Imager::Color set_internal() interal method no longer
36 calls the over-complicated ICL_set_internal() (which is retained
37 only for the old API.) Coverity complained that this leaked, but
38 this could only occur with an invalid (NULL pointer) color object.
8445279e 39 CID 185323.
b7346865 40
785364c1
TC
41 - the underlying implementation of the map() method could read before
42 the beginning on an allocated array if supplied with inconsistent
43 parameters, which Coverity complained about. No Imager code calls
44 that function with inconsistent parameters, but a
8445279e 45 belt-and-suspenders check was added. CID 185315.
785364c1 46
eb7e48c9
TC
47 - Coverity complained a call to i_getcolors(), used by the
48 implementation of the is_bilevel() method could leave the fetched
8445279e 49 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 50
c1c8b1e9
TC
51 - a numeric combining mode of 13 (eg. as a parameter to
52 Imager::Fill->new())could cause an invalid array read in
53 i_get_combine() due to a fencepost error in validating the combine
8445279e 54 number. CID 185299.

56Imager 1.008 - 31 Dec 2018
57============
58
75e155e1 59 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
60 This allows file formats that store EXIF data as blobs similarly
61 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 62
b5bbf161 63 - added some more file extensions to image file type mappings
75e155e1
TC
64
65 - added add_type_extensions() class method
66

TC
81Imager 1.006 - 26 Aug 2017
82============
83
ba7ddbae
TC
84 - the internal i_errors() function now correctly allocates the stack
85 space needed for its result.
86 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
87
88 - t/100-base/020-color.t now uses Imager::Test's test functions
89 instead of its own.
90 https://rt.cpan.org/Ticket/Display.html?id=111993
91
344dda51
TC
92 - write_multi() now returns an error result (a false value) if called
93 with a non-(Imager image object). Previously it would typically
94 crash.
95 https://rt.cpan.org/Ticket/Display.html?id=117878
96
97 - improve the documentation of the jpegquality parameter when
98 writing JPEG files.
99
100 - add code to mitigate CVE-2016-1238, Imager will no longer search the
101 default current directory entry in @INC when searching for file
102 format support modules.

110 - revert the ivdformat probes, they don't work as is and trying to
111 fix them is too much work for now.

TC
113Imager 1.004_004 - 15 Apr 2016
114================
115
9c45cc49
TC
116 - test that the ivdformat from Config is correct and look for a valid
117 one if it isn't.
118 For the strange Win32 failures.
119
120 - fix a copy and paste error in pod in samples/samp-form.cgi
121

TC
122Imager 1.004_003 - 23 Mar 2016
123================
124
bd2d657d
TC
125 - add some extra error reporting to the I/O layers tests, this might
126 help catch a failure seen on Win32.

129Imager 1.004_002 - 20 Mar 2016
130================
131
735b3e7b
TC
132 - don't use the seek() method on opened() handles in
133 t/200-file/400-basic.t. In older versions of perl such handles are
134 only IO::Handle objects, not IO::File, and don't have a seek()
135 method.

TC
137Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
138================
139
08914ed1
TC
140 - re-work the t/200-file/400-basic.t to correctly handle failures
141 It's custom ok() function didn't have a prototype and didn't use scalar().
142 This caused ok() to use the note instead of the value being tested when
143 the method called returned an empty list. For an example of the problem
e6226ce5 144 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 145
a2791e47
TC
146 - remove some noise from when Imager tried to work with bugs in old
147 versions of giflib. I can't do much about the new bugs.
08914ed1 148
e6226ce5
TC
149 - the new autolevels filter (Imager 0.99) used an integer for the
150 sample scaling factor which caused the top output level to be too
151 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
152 https://rt.cpan.org/Ticket/Display.html?id=111871
153
e6226ce5 154 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
155 minimum and maximum luminance from the histogram. This slightly
156 reduced the contrast of the output image.
157 https://rt.cpan.org/Ticket/Display.html?id=111871
158
159 - the new autolevels filter now uses a lookup table for 8-bit images
160 to avoid a floating point multiply for each sample.
161 https://rt.cpan.org/Ticket/Display.html?id=111871
162
e6226ce5
TC
163 - fixed several memory leaks detected by valgrind:
164
165 - addcolors() leaked the temporary array of colors supplied to the
166 internal API
167
168 - make_palette() leaked the temporary image array (not the images
169 themselves) passed to the internal API.
170
171 - combine()/i_combine() leaked its working row buffers
172
173 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
174 buffer if there were too many colors
175
176 - getcolorcount()/i_count_colors() leaked the sample buffer if
177 there were too many colors.
178
179 - the nearest_color filter (undocumented until I find a use for it)
180 leaked both temporaries passed to the API and internal buffers
181
a2791e47
TC
182 - the internal process of upgrading a paletted image to a direct
183 color image would leak a context object reference count.
184
185 - a write failure when writing to a GIF file could leak memory.
186
187 - failing to write to a 1-bit/pixel ICO image could leak memory.
188
189 - Imager no longer deliberately leaks the context object from the
190 initial thread. This was done to ensure there was always a context
191 object available, but the code that needed that now handles the
192 lack correctly,
193
e6226ce5
TC
194 - fixed some uninitialized memory usage detected by valgrind:
195
196 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
197 i_matrix_transform_bg() didn't initialize a working color value
198 if there was zero pixel coverage.
199
200 - i_ft2_cp() didn't initialize the complete color when producing an
201 intermediate image. This caused uninitialized value usage when
202 logging the color.

207 - Imager::Color::Table is now pre-loaded by the preload() method.
208 https://rt.cpan.org/Ticket/Display.html?id=104896
209
210 - fix an assertion triggered under perl 5.23.4.
211 Thanks to A. Sinan Unur for the report and the patch.
212
7b638aba
TC
213 - Imager->new can now be used to read raw image files.

220Imager 1.003 - 12 May 2015
221============
222
0fda3cfd
TC
223 - update 1.002 release notes to include the center change for filled
224 circle drawing.
225
226 - flood_fill() would escape beyond a 4-connected space under some
227 circumstances.
228 Added many more flood_fill() tests.

TC
231Imager 1.002 - 3 Apr 2015
232============
233
334b8922
TC
234 - drawing anti-aliased filled circles is now 10 to 50 times faster
235 depending on the size of the circle.
0fda3cfd
TC
236 This also changed the center from being the center of the pixel to
237 being the top left of the pixel to match the filled arcs drawn by
238 arc().
334b8922
TC
239 https://rt.cpan.org/Ticket/Display.html?id=101682
240
241 - enhancements to polygon filling:
242
243 - added a mode parameter to control how overlapping regions behave
244
245 - added a polypolygon() method to fill more than one polygon at a
246 time
247
248 - polygon filling is now exposed through the API.
249
45c8e262
TC
250 - added colormodel(), alphachannel() and colorchannels() methods.
251 These were added for two reasons:
252
253 - a future version of Imager may allow the number of channels in
254 an image to not directly represent the color model of an image.
255 eg. a greyscale TIFF image with multiple alpha channels.
256
257 - a future version of Imager may allow an image to be read without
258 translation, for example a TIFF file that contains measurements
0fda3cfd 259 from an instrument. Currently Imager transforms the samples into
d96c4de8 260 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
261 the value back.
262
263 An untranslated image would be unusable as image data, so
264 colormodel() would return "unknown" in this case.
265
266 Similarly a CMYK image might be returned as an "unknown" color
267 model image, if the caller chooses to disable translation to
268 RGB.

273 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
274 Thanks to Slaven Rezic for the report and the patch.

277 - GIF: clean-up a test file if the test for the giflib 4.2.0 file
278 version bug fails.
279
280 - fix Imager::Matrix2d::rotate()'s centre point handling
281 https://rt.cpan.org/Public/Bug/Display.html?id=99959
282

298Imager 1.000 - 28 Jul 2014
299============
300
301There's nothing special about Imager 1.000, it's just another release.
302
fa3dac1d
TC
303 - fix the skip check for the iolayer qr// buffer test
304
305 - improve error reporting for the iolayer test failing on a small
306 number of Win32 CPAN testers

TC
308Imager 0.99_02 - 21 Jul 2014
309==============
310
5dab5b9a
TC
311 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
312 the blue channel in the generated palette, and allow each color
313 component to be in the range 100..255 instead of just 100..254.
314 Thanks to Ralf Neubauer.
315 https://rt.cpan.org/Ticket/Display.html?id=97086
316
317 - revert "improved the XS for i_io_read() and i_io_raw_read()"
318 This caused problems with older perls and didn't provide much of a
319 performance improvement.
320
5bf25bc2 321 - support Inline 0.57 and later.
6d47a6af 322 Inline 0.57 changed the "with" interface.

6d47a6af
TC
325 - don't define our own MAXINT macro, it conflicts with windows header
326 files and in a few places it was the wrong value to use anyway.

331
7b486870
TC
332 - GIF: add support for giflib 5.1.0, which added error code pointer
333 parameters to EGifCloseFile() and DGifCloseFile().
334 https://rt.cpan.org/Ticket/Display.html?id=96756
335
336 - GIF: avoid a double-free when do_write() fails.
337
28104a85 338 - fix SV type probing to work on perl before 5.12. Broken in 0.99.

345Imager 0.99 - 25 Jun 2014
346===========
347
dce1523b
TC
348 - Imager::IO->new_buffer() (and hence Imager->read()'s data
349 parameter) now accepts a reference to a scalar as well as just a
350 plain scalar.
6a160bce 351 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
352
353 - Imager::IO->new_buffer() now always makes a copy of the passed in
354 buffer to avoid problems with temporary objects used for the return
355 value of SvPVbyte().
6a160bce 356 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 357

358 - improved the XS for i_io_read() and i_io_raw_read()
359 https://rt.cpan.org/Ticket/Display.html?id=92738
360
361 - load plugins from absolute paths on Android
362 Thanks to Brian Fraser.
363 https://rt.cpan.org/Ticket/Display.html?id=93272
364
6a160bce
TC
365 - added the jpeg_optimize parameter for writing JPEG files. This can
366 significantly reduce file sizes, but uses more memory and time.
367 https://rt.cpan.org/Ticket/Display.html?id=94292
368
14fd9e5d
TC
369 - the autolevels filter now works on the luminosity of the image
370 rather then working per channel. The old autolevels filter is
371 still available as "autolevels_skew".
372 https://rt.cpan.org/Ticket/Display.html?id=94413
373
75d54149
TC
374 - Imager::File::PNG now supports libpng 1.6.10.
375 1.6.10 changed CRC errors from benign errors to normal errors,
376 which broke the test which used CRC errors to check for benign
377 error support. Switched to using a 1-bit grey-scale image with a
378 palette to test for benign errors.

381Imager 0.98 - 3 Jan 2014
382===========
383
f84f86a2
TC
384Incompatible changes:
385
386 - the return value of setpixel() has changed.
387
388 Previously the return values for undrawable pixels vs caller errors
389 changed depending on whether you used the multiple pixel calling
390 mechanism, or the single pixel mechanism.
391
392 Now:
393
394 - for an invalid parameter, such as an unknown colour, or missing
395 parameter, an empty list (or undef in scalar context) is
396 returned, and errstr() is set,
397
398 - otherwise the number of pixels drawn is returned. If none of
399 the pixels could be drawn (they were all outside the image), "0
400 but true" is returned.
401
402 https://rt.cpan.org/Ticket/Display.html?id=87650
403
404Other changes:
405
6ba09ab9
TC
406 - when drawing on an image with an alpha channel where the source
407 minimum is greater than zero, Imager would read from beyond the end
408 of a malloc() allocated buffer. In rare circumstances this could
409 lead to some of the source image not being written to the target
410 image, or possibly to a segmentation fault.
411 I don't believe this has any security concerns beyond that.
412
0d052fd9
TC
413 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
414 text drawn would be nonsense. This would also read beyond the end
415 of a malloced buffer.
416
13671b17
TC
417 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
418 truncated early.
419 https://rt.cpan.org/Ticket/Display.html?id=88993
420
d6f4e964
TC
421 - Imager::Font::Wrap no longer requires the image parameter.

424 - a documentation typo fix in Imager::Transformations
425 Thanks to Adrian Yee.

427
0179ecd6
TC
428 - Image::Probe, Imager's internal module for probing library
429 locations now searches the directories specified by LD_RUN_PATH,
430 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
431 and the corresponing s/\blib$/include/ directories for header
432 files.

466 Mixed SampleFormat are handled incorrectly, since libtiff returns
467 only the first SampleFormat value, and an image with both an alpha
468 channel and SampleFormat = 2 for color channels probably has a
469 different SampleFormat for the alpha channel.

718 - The size of rotated images is no longer rounded up so aggressively.
719 Added rounding to the linear interpolation done for rotate() and
720 matrix_transform() for 1 and 3 channel 8-bit images.
721 Adjusted the two tranlate matrices used to build the final rotation
722 matrix to use the distance between the outlier pixels rather than
723 the pixel dimensions (ie. dimension-1).
724 With all of this the output of rotate(degrees => 270) on an 8-bit
725 image exactly matches the output of rotate(right => 270).

728Other changes:
729
730 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
731 internals, those names only matter for the XS interface.
732
733 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
734 the API level compiled into a loadable module such as
735 Imager::File::GIF doesn't match that of Imager. Previously it
736 could be difficult to determine exactly which module was failing to
737 load.
738 https://rt.cpan.org/Ticket/Display.html?id=77173
739
740 - added Imager->check_file_limits() as an interface to the
741 i_int_check_image_file_limits() API.
742

TC
758 - when downconverting samples (eg. from floating point to 8 bit)
759 Imager now rounds the sample value rather than attempting to
760 allocate input values over output values equally. The old
761 behaviour had the probably surprising effect of converting a
762 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
763 2.
764 This may result in slightly different 8 or 16-bit output images.
765
e2a86bac
TC
766 - BI_BITFIELD BMP images were handled incorrectly, both in
767 incorrectly calculating the space required for the masks and in
768 processing the image data itself.
769 https://rt.cpan.org/Ticket/Display.html?id=76736
770
771 - some odd width BMP BI_RLE4 images use run lengths that run one off
772 the edge of the image. Imager now allows this, discarding the
773 extra column.
774
775 - odd length RLE4 runs in BMP images were decoded incorrectly.

777 - pkg-config could sometimes return a library that was in a directory
778 EU::MM / $Config{libpth} doesn't know about, but the compiler did.

780 EU::MM can find the library, and if not, search our configured

785 common for static linking, eg. libpng requires libz.
786 https://rt.cpan.org/Ticket/Display.html?id=74043
787
788 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.

791 handle a statically linked libpng.
792 https://rt.cpan.org/Ticket/Display.html?id=74043
793
794 - if a probe includes testcode, Imager::Probe now checks that code as
795 part of the process of checking each configuration rather than as a
796 post test of the found configuration. This allows alternate
797 configurations to be checked if a matching but non-working
798 configuration is found.

1036 - io_glue I/O buffering re-work:
1037
1038 - reorganize io_glue to do it's own buffering by default
1039
1040 - the unbuffered functions are available as i_io_raw_read() (or
1041 raw_read() from perl) etc but are not recommended for typical
1042 use.
1043
1044 - use the new i_io_peekn() when checking for file magic to avoid
1045 seek, allowing Imager to detect the file type and read the file
1046 from an unseekable stream (for formats that don't use random
1047 access)
1048
1049 - added several new I/O layer API functions.
1050
1051 - fix the TGA performance problem, most noticably on Win32
1052 https://rt.cpan.org/Ticket/Display.html?id=70037

1054 - TIFF now uses wrapper functions of the correct types to avoid casts
1055 https://rt.cpan.org/Ticket/Display.html?id=69912
1056
1057 - the callback IO object did its own buffering, controlled by the
1058 maxbuffer parameter supplied to the read() and write() methods.
1059 This buffering has been removed, to avoid redundancy with the
1060 common io_glue buffering. This also avoids a bug in that code
1061 which could rarely pass a zero length to the read callback and
1062 then panic about the result.
1063
1064 - the callback IO object now tests the result of calling the close
1065 callback, which should return true for success.
1066
1067 - the PNM reader did its own buffering. This buffering has been
1068 removed to avoid redundancy with the common io_glue buffering.
1069
1070 - previously the read handlers for fd and callback I/O layers would
1071 call the underlying interface (POSIX read or your supplied callback)
1072 until it filled the buffer. It now only makes one call.
1073
1074 - added public constructors for I/O layer objects (see Imager::IO)
1075
1076 - all core file handlers now use the i_io_foo() wrappers to gain
1077 access to buffered I/O rather than calling the I/O layer
1078 callbacks directly.
1079
1080 - all core file handlers now check for error on close.
1081
1082 - Backward compatibility: if you hava custom file handlers, you can
1083 use i_io_write() etc since they're available as macros in older
1084 versions of Imager.
1085
1086 - eliminate the final remnants of io_glue_commit_types().
1087
1088 - bump IMAGER_API_VERSION, since the above may break assumptions.
1089
1090 - removed the long unused i_gen_reader() and i_gen_writer() utility
1091 functions.

1154Development release as a sanity check for the types re-work.
8d14daab
TC
1155
1156Massive types re-work:
1157
1158 - the type used internally for pixel co-ordinates and image sizes is
1159 now 64-bit on 64-bit platforms (at least sane ones).
1160
1161 - size_t is now used consistently for memory block sizes.
1162
1163 - since this changes the binary interface, the Imager API version has
1164 been incremented. Any module that uses the API will need to be
1165 rebuilt. In most cases that will be enough, but calls to any APIs
1166 that take a pointer to image sizes may need source changes.
1167
1168 - you should be able to create very large images on 64-bit systems,
1169 if you have enough memory. Successfully created a 32768 x 49192 x
1170 3 channel image, filled with a tiled image and scaled it. The
1171 unscaled image was also successfully saved to a JPEG.
1172
1173 - check the image size before attempting to write BMP, GIF, JPEG,
1174 PNG, SGI, TGA, TIFF images.
1175
1176 - correctly handle reading TGA images over 32767 pixels wide or tall.
1177
1178Incidental changes:
1179
1180 - the gif_left and gif_top tags are now clamped to non-negative
1181 values when writing a GIF image.
1182
1183 - removed dead callback read/write code
1184
1185The default maximum memory size when reading files is now 1G.

1804
1805 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1806 resulting in a SIGSEGV when attempting to scale an image to a size
1807 too large to fit in memory. This is a NULL pointer access issue,
1808 not a buffer overflow.

1823This release primarily contains changes to improve ease of use -
1824rather than you having to convert images to the appropriate number of
1825channels, Imager handles it internally. How to handle drawing colors
1826and the default combine mode is a thornier problem left for some other
1827release.

TC
1832 - moved the imtoc.perl code into Imager::Preprocess
1833
1834 - paste() and rubthrough() now adapt the source image data to the
1835 destination, so you can now safely paste/rubthrough from greyscale
1836 images to color images or back, or from alpha channel images to
1837 noalpha channels or back.
1838 https://rt.cpan.org/Ticket/Display.html?id=30908
1839
1840 - rubthrough() now falls back to pasting when the source doesn't have
1841 an alpha channel. This effectively treats the source as having a
1842 max alpha channel, the right thing to do.
1843 http://rt.cpan.org/Ticket/Display.html?id=29944
1844
1845 - re-worked most of the area filling code to use a common set of
1846 functions when filling.
1847 Corrected normal combine mode.
1848 Rewrote most of the combine modes to match the way the SVG draft
1849 defines them with respect to a translucent source and destination.
1850 Added tests for translucent source and destination.
1851 Added tests to check 8-bit/sample and double/sample combines work
1852 similarly.

1891 - handling of the left-over bit for 16-bit/pixel TGA images has been
1892 changed to match the behaviour of the GIMP. Previously the bit
1893 being set was treated as an opaque pixel, but one user reported a
1894 problem with loading such an image. I haven't been able to find any
1895 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1896 I'll match it's behaviour. See issue 114913 in the GIMP's
1897 bugzilla.

1907 - the old dynaload code used Mach API functions to load dynamic
1908 libraries on Mac OS X. These APIs have been deprecated in OS X

2183Bug fixes:
2184
2185 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
2186 was returning an image object with an extra reference, this
2187 resulted in a memory leak.
2188 http://rt.cpan.org/Ticket/Display.html?id=24992
2189
2190 - fix rendering on alpha channel images for the FreeType 2.x driver
2191 http://rt.cpan.org/Ticket/Display.html?id=11972

2194 supply a parameter to treat a short read as successful and set
2195 i_incomplete
2196 http://rt.cpan.org/Ticket/Display.html?id=8426
2197
2198 - previously, reading ASCII PBM files required spaces between samples,
2199 even though the format doesn't require that

2207
2208 - rewrite a conditional expression as an if() to hopefully work around
2209 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.

2215Imager 0.55 - 16 Dec 2006
2216===========
2217
2218This is primarily a bug fix release.
2219
2220Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2221
2222There is one new feature:
2223
2224 - the Win32 font driver now supports UTF8 (RT 22166)
2225 http://www.cpanforum.com/threads/3276
2226 http://rt.cpan.org/Ticket/Display.html?id=22166
2227
2228Several bugs were fixed:
2229
2230 - the string() method would not output the string "0"
2231 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2232
2233 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2234 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2235
2236 - the gif_disposal and gif_user_input tags weren't being read from
2237 the file correctly
2238 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2239
2240 - gif.c was failing to build under MSVC
2241 http://rt.cpan.org/Ticket/Display.html?id=23922
2242
2243 - in some cases strings passed to the string() method were treated as
2244 terminated by NUL (chr 0)
2245 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2246
2247 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2248 that's the default build name for zlib on Win32.
2249 http://rt.cpan.org/Ticket/Display.html?id=23064
2250
2251 - search $Config{incpath} for headers too, which we should have been
2252 doing all along.
2253
2254Win32 font driver fixes:
2255
2256 - the global descent value from bounding box was the wrong sign
2257 http://www.cpanforum.com/threads/3276
2258
2259 - if the first or last glyph overflowed the left or right side of the
2260 advance width they would be clipped
2261
2262
2263Imager 0.54 - 14 Sep 2006
2264===========
2265
2266This is primarily a feature release:
2267
2268 - a new qtype value 'mixing' has been added to the scale()
2269 method. This is faster than 'normal', slower than 'preview'. This
2270 is based on the method used by pnmscale, and seems to produce less
2271 blurry results than normal.
2272 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2273
2274 - the rubthrough() method can now render onto images with an alpha
2275 channel.
2276 http://rt.cpan.org/Ticket/Display.html?id=20678
2277
2278 - the read_multi() method now falls back to calling doing a single
2279 image read via the read() method and write_multi() will now fall
2280 back to calling write() if a single image is supplied. This means
2281 you can simply call the read_multi() or write_multi() functions
2282 without having to check if the type is formatted by that method.
2283 http://rt.cpan.org/Ticket/Display.html?id=19457
2284 http://rt.cpan.org/Ticket/Display.html?id=19458
2285
2286 - the GIF loop extension can now be written. If you don't have
2287 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2288 should upgrade.
2289 http://rt.cpan.org/Ticket/Display.html?id=21185
2290
2291 - getscanline() and setscanline() can now read/write palette index
2292 based data from/to the image for paletted images, by setting type to
2293 'index'.
2294 http://rt.cpan.org/Ticket/Display.html?id=20338
2295
2296 - we no longer hassle you to disable GIF support
2297 http://rt.cpan.org/Ticket/Display.html?id=20687
2298
2299 - minor documentation fixes
2300
2301
2302Imager 0.53 - 26 Jul 2006
2303===========
2304
2305This is a bugfix release.
2306
2307Some test code was left in a code path not covered by the test
2308suite. A test was added to cover this code path and the test code was
2309removed.
2310http://rt.cpan.org/Public/Bug/Display.html?id=20705
2311
2312
2313Imager 0.52 - 25 Jul 2006
2314===========
2315
2316This is primarily a feature release, but contains a fair few bug
2317fixes, new features:
2318
2319 - ability to read and write MS Windows ICO and CUR files
2320
2321 - you can now add file format plugins to support new file formats
2322
2323 - add POD coverage tests
2324
2325 - setcolors() and addcolors() now accept color names and so on
2326 instead of requiring Imager::Color objects.
2327 http://rt.cpan.org/Ticket/Display.html?id=20056
2328
2329 - flood_fill() can now fill to a specified border color instead of
2330 just to the area the same color as the seed.
2331 http://rt.cpan.org/Ticket/Display.html?id=19618
2332
2333
2334Bug fixes:
2335
2336 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2337 calculating the advance width.
2338 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2339
2340 - bounding_box for the T1 driver wasn't including leading and
2341 trailing spaces in the bounding box as the other drivers did, it also
2342 produced strange results for empty strings or strings containing only
2343 spaces
2344
2345 - when reading CMYK jpeg images they were being transferred to the
2346 image object as is, producing a four channel image. It only looked ok
2347 due to an old still unfixed Photoshop bug. We now convert from the
2348 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2349 http://rt.cpan.org/Ticket/Display.html?id=20416
2350
2351 - reading a CYMK TIFF would result in a 4 channel image, reading any
2352 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2353 result in an error.
2354 http://rt.cpan.org/Ticket/Display.html?id=20415
2355
2356 - added /usr/local/include to the default include search path, since
2357 we were already searching /usr/local/lib for libraries.
2358
2359And various minor fixes and documentation updates.
2360
2361
2362Imager 0.51 - 23 Apr 2006

2366 a crash
2367 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2368
2369 - fix mis-processing of the src_maxx and src_maxy parameters of the
2370 paste() method
2371 http://rt.cpan.org/Public/Bug/Display.html?id=18712
2372
2373 - fix a problem in Imager's "smart" handling of the color parameter
2374 to various methods.
2375 http://rt.cpan.org/Public/Bug/Display.html?id=18561
2376
2377

2382 or 4 channel image to jpeg or a 2 channel image to tga where the
2383 output is an in-memeory buffer.
2384 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2385
2386 - fixes an incorrect pointer parameter in the PNG code
2387 http://rt.cpan.org/Public/Bug/Display.html?id=18051

2389 - skip Inline::C tests when building in a directory with spaces
2390 http://rt.cpan.org/Public/Bug/Display.html?id=18049
