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.
c1c8b1e9 55
c4fd43be
TC
56
57
58 - avoid an unneeded EXTEND() call when the FT1 has_chars()
59 implementation returns 0. CID 185350.
60
61 - avoid accessing a possibly NULL map from MakeMapObject() in a
62 logging call. (GIF) CID 185296.
63
4615ad8d
TC
64 - gradgen() allocated the wrong amount of space (always too much) for
65 the color array. CID 185291.
66
ea3099db
TC
67 - avoid dead code in i_tt_glyph_names(). CID 185321.
68
8b810590
TC
69 - avoid dead code in i_get_anonymous_color_histo(), which is the
70 implementation of getcolorusage(). CID 185327.
71
4eb9a521
TC
72 - avoid dead code in i_ft2_glyph_name(), which is the implementation
73 of glyph_names() for FT2. CID 185342.

75Imager 1.008 - 31 Dec 2018
76============
77
75e155e1 78 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
79 This allows file formats that store EXIF data as blobs similarly
80 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 81
b5bbf161 82 - added some more file extensions to image file type mappings
75e155e1
TC
83
84 - added add_type_extensions() class method

100Imager 1.006 - 26 Aug 2017
101============
102
ba7ddbae
TC
103 - the internal i_errors() function now correctly allocates the stack
104 space needed for its result.
105 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
106
107 - t/100-base/020-color.t now uses Imager::Test's test functions
108 instead of its own.
109 https://rt.cpan.org/Ticket/Display.html?id=111993
110
344dda51
TC
111 - write_multi() now returns an error result (a false value) if called
112 with a non-(Imager image object). Previously it would typically
113 crash.
114 https://rt.cpan.org/Ticket/Display.html?id=117878
115
116 - improve the documentation of the jpegquality parameter when
117 writing JPEG files.
118
119 - add code to mitigate CVE-2016-1238, Imager will no longer search the
120 default current directory entry in @INC when searching for file
121 format support modules.

123Imager 1.005 - 16 Apr 2016
124============
125
126It's now been ten years since I switched to the new Changes file in
127release 0.55.
128
cd0109d8
TC
129 - revert the ivdformat probes, they don't work as is and trying to
130 fix them is too much work for now.
131
6f1cbfed
TC
132Imager 1.004_004 - 15 Apr 2016
133================
134
9c45cc49
TC
135 - test that the ivdformat from Config is correct and look for a valid
136 one if it isn't.
137 For the strange Win32 failures.
138
139 - fix a copy and paste error in pod in samples/samp-form.cgi
140

TC
141Imager 1.004_003 - 23 Mar 2016
142================
143
bd2d657d
TC
144 - add some extra error reporting to the I/O layers tests, this might
145 help catch a failure seen on Win32.

TC
148Imager 1.004_002 - 20 Mar 2016
149================
150
735b3e7b
TC
151 - don't use the seek() method on opened() handles in
152 t/200-file/400-basic.t. In older versions of perl such handles are
153 only IO::Handle objects, not IO::File, and don't have a seek()
154 method.

TC
156Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
157================
158
08914ed1
TC
159 - re-work the t/200-file/400-basic.t to correctly handle failures
160 It's custom ok() function didn't have a prototype and didn't use scalar().
161 This caused ok() to use the note instead of the value being tested when
162 the method called returned an empty list. For an example of the problem
e6226ce5 163 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 164
a2791e47
TC
165 - remove some noise from when Imager tried to work with bugs in old
166 versions of giflib. I can't do much about the new bugs.
08914ed1 167
e6226ce5
TC
168 - the new autolevels filter (Imager 0.99) used an integer for the
169 sample scaling factor which caused the top output level to be too
170 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
171 https://rt.cpan.org/Ticket/Display.html?id=111871
172
e6226ce5 173 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
174 minimum and maximum luminance from the histogram. This slightly
175 reduced the contrast of the output image.
176 https://rt.cpan.org/Ticket/Display.html?id=111871
177
178 - the new autolevels filter now uses a lookup table for 8-bit images
179 to avoid a floating point multiply for each sample.
180 https://rt.cpan.org/Ticket/Display.html?id=111871
181
e6226ce5
TC
182 - fixed several memory leaks detected by valgrind:
183
184 - addcolors() leaked the temporary array of colors supplied to the
185 internal API
186
187 - make_palette() leaked the temporary image array (not the images
188 themselves) passed to the internal API.
189
190 - combine()/i_combine() leaked its working row buffers
191
192 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
193 buffer if there were too many colors
194
195 - getcolorcount()/i_count_colors() leaked the sample buffer if
196 there were too many colors.
197
198 - the nearest_color filter (undocumented until I find a use for it)
199 leaked both temporaries passed to the API and internal buffers
200
a2791e47
TC
201 - the internal process of upgrading a paletted image to a direct
202 color image would leak a context object reference count.
203
204 - a write failure when writing to a GIF file could leak memory.
205
206 - failing to write to a 1-bit/pixel ICO image could leak memory.
207
208 - Imager no longer deliberately leaks the context object from the
209 initial thread. This was done to ensure there was always a context
210 object available, but the code that needed that now handles the
211 lack correctly,
212
e6226ce5
TC
213 - fixed some uninitialized memory usage detected by valgrind:
214
215 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
216 i_matrix_transform_bg() didn't initialize a working color value
217 if there was zero pixel coverage.
218
219 - i_ft2_cp() didn't initialize the complete color when producing an
220 intermediate image. This caused uninitialized value usage when
221 logging the color.

TC
223Imager 1.004 - 8 Nov 2015
224============
225
5ebfb369
TC
226 - Imager::Color::Table is now pre-loaded by the preload() method.
227 https://rt.cpan.org/Ticket/Display.html?id=104896
228
229 - fix an assertion triggered under perl 5.23.4.
230 Thanks to A. Sinan Unur for the report and the patch.
231
7b638aba
TC
232 - Imager->new can now be used to read raw image files.
233 https://rt.cpan.org/Ticket/Display.html?id=106836
f7160b21 234 Thanks to Richard Kelsch for reporting this.
7b638aba
TC
235
236 - deal with output changes from Pod::Spell

TC
239Imager 1.003 - 12 May 2015
240============
241
0fda3cfd
TC
242 - update 1.002 release notes to include the center change for filled
243 circle drawing.
244
245 - flood_fill() would escape beyond a 4-connected space under some
246 circumstances.
247 Added many more flood_fill() tests.

TC
250Imager 1.002 - 3 Apr 2015
251============
252
334b8922
TC
253 - drawing anti-aliased filled circles is now 10 to 50 times faster
254 depending on the size of the circle.
0fda3cfd
TC
255 This also changed the center from being the center of the pixel to
256 being the top left of the pixel to match the filled arcs drawn by
257 arc().
334b8922
TC
258 https://rt.cpan.org/Ticket/Display.html?id=101682
259
260 - enhancements to polygon filling:
261
262 - added a mode parameter to control how overlapping regions behave
263
264 - added a polypolygon() method to fill more than one polygon at a
265 time
266
267 - polygon filling is now exposed through the API.
268
45c8e262
TC
269 - added colormodel(), alphachannel() and colorchannels() methods.
270 These were added for two reasons:
271
272 - a future version of Imager may allow the number of channels in
273 an image to not directly represent the color model of an image.
274 eg. a greyscale TIFF image with multiple alpha channels.
275
276 - a future version of Imager may allow an image to be read without
277 translation, for example a TIFF file that contains measurements
0fda3cfd 278 from an instrument. Currently Imager transforms the samples into
d96c4de8 279 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
280 the value back.
281
282 An untranslated image would be unusable as image data, so
283 colormodel() would return "unknown" in this case.
284
285 Similarly a CMYK image might be returned as an "unknown" color
286 model image, if the caller chooses to disable translation to
287 RGB.

289Imager 1.001 - 2 Jan 2015
290============

aca60e01
TC
292 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
293 Thanks to Slaven Rezic for the report and the patch.

0df260f6
TC
296 - GIF: clean-up a test file if the test for the giflib 4.2.0 file
297 version bug fails.

317Imager 1.000 - 28 Jul 2014
318============
319
320There's nothing special about Imager 1.000, it's just another release.
321
fa3dac1d
TC
322 - fix the skip check for the iolayer qr// buffer test
323
324 - improve error reporting for the iolayer test failing on a small
325 number of Win32 CPAN testers

TC
327Imager 0.99_02 - 21 Jul 2014
328==============
329
5dab5b9a
TC
330 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
331 the blue channel in the generated palette, and allow each color
332 component to be in the range 100..255 instead of just 100..254.
333 Thanks to Ralf Neubauer.
334 https://rt.cpan.org/Ticket/Display.html?id=97086
335
336 - revert "improved the XS for i_io_read() and i_io_raw_read()"
337 This caused problems with older perls and didn't provide much of a
338 performance improvement.
339
5bf25bc2 340 - support Inline 0.57 and later.
6d47a6af 341 Inline 0.57 changed the "with" interface.
5bf25bc2
TC
342 https://rt.cpan.org/Ticket/Display.html?id=97108
343
6d47a6af
TC
344 - don't define our own MAXINT macro, it conflicts with windows header
345 files and in a few places it was the wrong value to use anyway.

349==============
350
7b486870
TC
351 - GIF: add support for giflib 5.1.0, which added error code pointer
352 parameters to EGifCloseFile() and DGifCloseFile().
353 https://rt.cpan.org/Ticket/Display.html?id=96756
354
355 - GIF: avoid a double-free when do_write() fails.
356
28104a85 357 - fix SV type probing to work on perl before 5.12. Broken in 0.99.

364Imager 0.99 - 25 Jun 2014
365===========
366
dce1523b
TC
367 - Imager::IO->new_buffer() (and hence Imager->read()'s data
368 parameter) now accepts a reference to a scalar as well as just a
369 plain scalar.
6a160bce 370 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
371
372 - Imager::IO->new_buffer() now always makes a copy of the passed in
373 buffer to avoid problems with temporary objects used for the return
374 value of SvPVbyte().
6a160bce 375 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 376

377 - improved the XS for i_io_read() and i_io_raw_read()
378 https://rt.cpan.org/Ticket/Display.html?id=92738
379
380 - load plugins from absolute paths on Android
381 Thanks to Brian Fraser.
382 https://rt.cpan.org/Ticket/Display.html?id=93272
383
6a160bce
TC
384 - added the jpeg_optimize parameter for writing JPEG files. This can
385 significantly reduce file sizes, but uses more memory and time.
386 https://rt.cpan.org/Ticket/Display.html?id=94292
387
14fd9e5d
TC
388 - the autolevels filter now works on the luminosity of the image
389 rather then working per channel. The old autolevels filter is
390 still available as "autolevels_skew".
391 https://rt.cpan.org/Ticket/Display.html?id=94413
392
75d54149
TC
393 - Imager::File::PNG now supports libpng 1.6.10.
394 1.6.10 changed CRC errors from benign errors to normal errors,
395 which broke the test which used CRC errors to check for benign
396 error support. Switched to using a 1-bit grey-scale image with a
397 palette to test for benign errors.

400Imager 0.98 - 3 Jan 2014
401===========
402
f84f86a2
TC
403Incompatible changes:
404
405 - the return value of setpixel() has changed.
406
407 Previously the return values for undrawable pixels vs caller errors
408 changed depending on whether you used the multiple pixel calling
409 mechanism, or the single pixel mechanism.
410
411 Now:
412
413 - for an invalid parameter, such as an unknown colour, or missing
414 parameter, an empty list (or undef in scalar context) is
415 returned, and errstr() is set,
416
417 - otherwise the number of pixels drawn is returned. If none of
418 the pixels could be drawn (they were all outside the image), "0
419 but true" is returned.
420
421 https://rt.cpan.org/Ticket/Display.html?id=87650
422
423Other changes:
424
6ba09ab9
TC
425 - when drawing on an image with an alpha channel where the source
426 minimum is greater than zero, Imager would read from beyond the end
427 of a malloc() allocated buffer. In rare circumstances this could
428 lead to some of the source image not being written to the target
429 image, or possibly to a segmentation fault.
430 I don't believe this has any security concerns beyond that.
431
0d052fd9
TC
432 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
433 text drawn would be nonsense. This would also read beyond the end
434 of a malloced buffer.
435
13671b17
TC
436 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
437 truncated early.

485 Mixed SampleFormat are handled incorrectly, since libtiff returns

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

747Other changes:
748
749 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
750 internals, those names only matter for the XS interface.
751
752 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
753 the API level compiled into a loadable module such as
754 Imager::File::GIF doesn't match that of Imager. Previously it
755 could be difficult to determine exactly which module was failing to
756 load.
757 https://rt.cpan.org/Ticket/Display.html?id=77173
758
759 - added Imager->check_file_limits() as an interface to the
760 i_int_check_image_file_limits() API.
761

29b38678
TC
777 - when downconverting samples (eg. from floating point to 8 bit)
778 Imager now rounds the sample value rather than attempting to
779 allocate input values over output values equally. The old
780 behaviour had the probably surprising effect of converting a
781 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
782 2.
783 This may result in slightly different 8 or 16-bit output images.
784
e2a86bac
TC
785 - BI_BITFIELD BMP images were handled incorrectly, both in
786 incorrectly calculating the space required for the masks and in
787 processing the image data itself.
788 https://rt.cpan.org/Ticket/Display.html?id=76736
789
790 - some odd width BMP BI_RLE4 images use run lengths that run one off
791 the edge of the image. Imager now allows this, discarding the
792 extra column.
793
794 - odd length RLE4 runs in BMP images were decoded incorrectly.

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

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

804 common for static linking, eg. libpng requires libz.
805 https://rt.cpan.org/Ticket/Display.html?id=74043
806
807 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.

810 handle a statically linked libpng.
811 https://rt.cpan.org/Ticket/Display.html?id=74043
812
813 - if a probe includes testcode, Imager::Probe now checks that code as
814 part of the process of checking each configuration rather than as a
815 post test of the found configuration. This allows alternate
816 configurations to be checked if a matching but non-working
817 configuration is found.

893 - setsamples() is now a true complement to getsamples() - it can
894 write 8-bit or floating point samples from a scalar or array
895 reference. This adds i_psamp() and i_psampf() to the C level API.
896
897 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
898 changed to make better use of the typemap, but these aren't part of
899 the perl level API anyway. There were no changes to the C level
900 interfaces to these functions.

1055 - io_glue I/O buffering re-work:
1056
1057 - reorganize io_glue to do it's own buffering by default
1058
1059 - the unbuffered functions are available as i_io_raw_read() (or
1060 raw_read() from perl) etc but are not recommended for typical
1061 use.
1062
1063 - use the new i_io_peekn() when checking for file magic to avoid
1064 seek, allowing Imager to detect the file type and read the file
1065 from an unseekable stream (for formats that don't use random
1066 access)
1067
1068 - added several new I/O layer API functions.
1069
1070 - fix the TGA performance problem, most noticably on Win32
1071 https://rt.cpan.org/Ticket/Display.html?id=70037

1073 - TIFF now uses wrapper functions of the correct types to avoid casts
1074 https://rt.cpan.org/Ticket/Display.html?id=69912
1075
1076 - the callback IO object did its own buffering, controlled by the
1077 maxbuffer parameter supplied to the read() and write() methods.
1078 This buffering has been removed, to avoid redundancy with the
1079 common io_glue buffering. This also avoids a bug in that code
1080 which could rarely pass a zero length to the read callback and
1081 then panic about the result.
1082
1083 - the callback IO object now tests the result of calling the close
1084 callback, which should return true for success.
1085
1086 - the PNM reader did its own buffering. This buffering has been
1087 removed to avoid redundancy with the common io_glue buffering.
1088
1089 - previously the read handlers for fd and callback I/O layers would
1090 call the underlying interface (POSIX read or your supplied callback)
1091 until it filled the buffer. It now only makes one call.
1092
1093 - added public constructors for I/O layer objects (see Imager::IO)
1094
1095 - all core file handlers now use the i_io_foo() wrappers to gain
1096 access to buffered I/O rather than calling the I/O layer
1097 callbacks directly.
1098
1099 - all core file handlers now check for error on close.
1100
1101 - Backward compatibility: if you hava custom file handlers, you can
1102 use i_io_write() etc since they're available as macros in older
1103 versions of Imager.
1104
1105 - eliminate the final remnants of io_glue_commit_types().
1106
1107 - bump IMAGER_API_VERSION, since the above may break assumptions.
1108
1109 - removed the long unused i_gen_reader() and i_gen_writer() utility
1110 functions.

TC
1174
1175Massive types re-work:
1176
1177 - the type used internally for pixel co-ordinates and image sizes is
1178 now 64-bit on 64-bit platforms (at least sane ones).
1179
1180 - size_t is now used consistently for memory block sizes.
1181
1182 - since this changes the binary interface, the Imager API version has
1183 been incremented. Any module that uses the API will need to be
1184 rebuilt. In most cases that will be enough, but calls to any APIs
1185 that take a pointer to image sizes may need source changes.
1186
1187 - you should be able to create very large images on 64-bit systems,
1188 if you have enough memory. Successfully created a 32768 x 49192 x
1189 3 channel image, filled with a tiled image and scaled it. The
1190 unscaled image was also successfully saved to a JPEG.
1191
1192 - check the image size before attempting to write BMP, GIF, JPEG,
1193 PNG, SGI, TGA, TIFF images.
1194
1195 - correctly handle reading TGA images over 32767 pixels wide or tall.
1196
1197Incidental changes:
1198
1199 - the gif_left and gif_top tags are now clamped to non-negative
1200 values when writing a GIF image.
1201
1202 - removed dead callback read/write code
1203
1204The default maximum memory size when reading files is now 1G.

1814 - Possible security issue: The floating point sample path for image

1823
1824 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1825 resulting in a SIGSEGV when attempting to scale an image to a size
1826 too large to fit in memory. This is a NULL pointer access issue,
1827 not a buffer overflow.
1828 Added a check for the failure.
1829 scale_calculate() (and hence scale()) will now fail if any of the
1830 scale size parameters are a reference.

1842This release primarily contains changes to improve ease of use -
1843rather than you having to convert images to the appropriate number of
1844channels, Imager handles it internally. How to handle drawing colors
1845and the default combine mode is a thornier problem left for some other
1846release.

TC
1851 - moved the imtoc.perl code into Imager::Preprocess
1852
1853 - paste() and rubthrough() now adapt the source image data to the
1854 destination, so you can now safely paste/rubthrough from greyscale
1855 images to color images or back, or from alpha channel images to
1856 noalpha channels or back.
1857 https://rt.cpan.org/Ticket/Display.html?id=30908
1858
1859 - rubthrough() now falls back to pasting when the source doesn't have
1860 an alpha channel. This effectively treats the source as having a
1861 max alpha channel, the right thing to do.
1862 http://rt.cpan.org/Ticket/Display.html?id=29944
1863
1864 - re-worked most of the area filling code to use a common set of
1865 functions when filling.
1866 Corrected normal combine mode.
1867 Rewrote most of the combine modes to match the way the SVG draft
1868 defines them with respect to a translucent source and destination.
1869 Added tests for translucent source and destination.
1870 Added tests to check 8-bit/sample and double/sample combines work
1871 similarly.

1909
1910 - handling of the left-over bit for 16-bit/pixel TGA images has been
1911 changed to match the behaviour of the GIMP. Previously the bit
1912 being set was treated as an opaque pixel, but one user reported a
1913 problem with loading such an image. I haven't been able to find any
1914 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1915 I'll match it's behaviour. See issue 114913 in the GIMP's
1916 bugzilla.

1926 - the old dynaload code used Mach API functions to load dynamic
1927 libraries on Mac OS X. These APIs have been deprecated in OS X
1928 10.5 and were causing some build problems.

1930 will need version 10.3 or later of OS X.

2163 function for a library. Disabled the default (non-freetype-config)
2164 library probe and added an extra probe function that searches for
2165 both ft2build.h and whatever it includes, and adds -I as needed.
2166 Hopefully this will fix build problems like

2202Bug fixes:
2203
2204 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
2205 was returning an image object with an extra reference, this
2206 resulted in a memory leak.

2234Imager 0.55 - 16 Dec 2006
2235===========
2236
2237This is primarily a bug fix release.
2238
2239Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2240
2241There is one new feature:
2242
2243 - the Win32 font driver now supports UTF8 (RT 22166)
2244 http://www.cpanforum.com/threads/3276
2245 http://rt.cpan.org/Ticket/Display.html?id=22166
2246
2247Several bugs were fixed:
2248
2249 - the string() method would not output the string "0"
2250 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2251
2252 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2253 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2254
2255 - the gif_disposal and gif_user_input tags weren't being read from
2256 the file correctly
2257 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2258
2259 - gif.c was failing to build under MSVC
2260 http://rt.cpan.org/Ticket/Display.html?id=23922
2261
2262 - in some cases strings passed to the string() method were treated as
2263 terminated by NUL (chr 0)
2264 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2265
2266 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2267 that's the default build name for zlib on Win32.
2268 http://rt.cpan.org/Ticket/Display.html?id=23064
2269
2270 - search $Config{incpath} for headers too, which we should have been
2271 doing all along.
2272
2273Win32 font driver fixes:
2274
2275 - the global descent value from bounding box was the wrong sign
2276 http://www.cpanforum.com/threads/3276
2277
2278 - if the first or last glyph overflowed the left or right side of the
2279 advance width they would be clipped
2280
2281
2282Imager 0.54 - 14 Sep 2006
2283===========
2284
2285This is primarily a feature release:
2286
2287 - a new qtype value 'mixing' has been added to the scale()
2288 method. This is faster than 'normal', slower than 'preview'. This
2289 is based on the method used by pnmscale, and seems to produce less
2290 blurry results than normal.
2291 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2292
2293 - the rubthrough() method can now render onto images with an alpha
2294 channel.
2295 http://rt.cpan.org/Ticket/Display.html?id=20678
2296
2297 - the read_multi() method now falls back to calling doing a single
2298 image read via the read() method and write_multi() will now fall
2299 back to calling write() if a single image is supplied. This means
2300 you can simply call the read_multi() or write_multi() functions
2301 without having to check if the type is formatted by that method.
2302 http://rt.cpan.org/Ticket/Display.html?id=19457
2303 http://rt.cpan.org/Ticket/Display.html?id=19458
2304
2305 - the GIF loop extension can now be written. If you don't have
2306 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2307 should upgrade.
2308 http://rt.cpan.org/Ticket/Display.html?id=21185
2309
2310 - getscanline() and setscanline() can now read/write palette index
2311 based data from/to the image for paletted images, by setting type to
2312 'index'.
2313 http://rt.cpan.org/Ticket/Display.html?id=20338
2314
2315 - we no longer hassle you to disable GIF support
2316 http://rt.cpan.org/Ticket/Display.html?id=20687
2317
2318 - minor documentation fixes
2319
2320
2321Imager 0.53 - 26 Jul 2006
2322===========
2323
2324This is a bugfix release.
2325
2326Some test code was left in a code path not covered by the test
2327suite. A test was added to cover this code path and the test code was
2328removed.
2329http://rt.cpan.org/Public/Bug/Display.html?id=20705
2330
2331
2332Imager 0.52 - 25 Jul 2006
2333===========
2334
2335This is primarily a feature release, but contains a fair few bug
2336fixes, new features:
2337
2338 - ability to read and write MS Windows ICO and CUR files
2339
2340 - you can now add file format plugins to support new file formats
2341
2342 - add POD coverage tests
2343
2344 - setcolors() and addcolors() now accept color names and so on
2345 instead of requiring Imager::Color objects.
2346 http://rt.cpan.org/Ticket/Display.html?id=20056
2347
2348 - flood_fill() can now fill to a specified border color instead of
2349 just to the area the same color as the seed.
2350 http://rt.cpan.org/Ticket/Display.html?id=19618
2351
2352
2353Bug fixes:
2354
2355 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2356 calculating the advance width.
2357 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2358
2359 - bounding_box for the T1 driver wasn't including leading and
2360 trailing spaces in the bounding box as the other drivers did, it also
2361 produced strange results for empty strings or strings containing only
2362 spaces
2363
2364 - when reading CMYK jpeg images they were being transferred to the
2365 image object as is, producing a four channel image. It only looked ok
2366 due to an old still unfixed Photoshop bug. We now convert from the
2367 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2368 http://rt.cpan.org/Ticket/Display.html?id=20416
2369
2370 - reading a CYMK TIFF would result in a 4 channel image, reading any
2371 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2372 result in an error.
2373 http://rt.cpan.org/Ticket/Display.html?id=20415
2374
2375 - added /usr/local/include to the default include search path, since
2376 we were already searching /usr/local/lib for libraries.
2377
2378And various minor fixes and documentation updates.
2379
2380
2381Imager 0.51 - 23 Apr 2006

2385 a crash
2386 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2387
2388 - fix mis-processing of the src_maxx and src_maxy parameters of the
2389 paste() method
2390 http://rt.cpan.org/Public/Bug/Display.html?id=18712
