TC
17 - the internal i_errors() function now correctly allocates the stack
18 space needed for its result.
19 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
20
21 - t/100-base/020-color.t now uses Imager::Test's test functions
22 instead of its own.

24
344dda51
TC
25 - write_multi() now returns an error result (a false value) if called
26 with a non-(Imager image object). Previously it would typically
27 crash.
28 https://rt.cpan.org/Ticket/Display.html?id=117878
29
30 - improve the documentation of the jpegquality parameter when
31 writing JPEG files.
32
33 - add code to mitigate CVE-2016-1238, Imager will no longer search the
34 default current directory entry in @INC when searching for file
35 format support modules.

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

46Imager 1.004_004 - 15 Apr 2016
47================
48

TC
49 - test that the ivdformat from Config is correct and look for a valid
50 one if it isn't.
51 For the strange Win32 failures.
52
53 - fix a copy and paste error in pod in samples/samp-form.cgi

56================
57
bd2d657d
TC
58 - add some extra error reporting to the I/O layers tests, this might
59 help catch a failure seen on Win32.

63================
64
735b3e7b
TC
65 - don't use the seek() method on opened() handles in
66 t/200-file/400-basic.t. In older versions of perl such handles are
67 only IO::Handle objects, not IO::File, and don't have a seek()
68 method.

70Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
71================
72
08914ed1
TC
73 - re-work the t/200-file/400-basic.t to correctly handle failures
74 It's custom ok() function didn't have a prototype and didn't use scalar().
75 This caused ok() to use the note instead of the value being tested when
76 the method called returned an empty list. For an example of the problem
e6226ce5 77 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 78
a2791e47
TC
79 - remove some noise from when Imager tried to work with bugs in old
80 versions of giflib. I can't do much about the new bugs.
08914ed1 81
e6226ce5
TC
82 - the new autolevels filter (Imager 0.99) used an integer for the
83 sample scaling factor which caused the top output level to be too
84 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
85 https://rt.cpan.org/Ticket/Display.html?id=111871
86
e6226ce5 87 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
88 minimum and maximum luminance from the histogram. This slightly
89 reduced the contrast of the output image.
90 https://rt.cpan.org/Ticket/Display.html?id=111871
91
92 - the new autolevels filter now uses a lookup table for 8-bit images
93 to avoid a floating point multiply for each sample.
94 https://rt.cpan.org/Ticket/Display.html?id=111871
95
e6226ce5
TC
96 - fixed several memory leaks detected by valgrind:
97
98 - addcolors() leaked the temporary array of colors supplied to the
99 internal API
100
101 - make_palette() leaked the temporary image array (not the images
102 themselves) passed to the internal API.
103
104 - combine()/i_combine() leaked its working row buffers
105
106 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
107 buffer if there were too many colors
108
109 - getcolorcount()/i_count_colors() leaked the sample buffer if
110 there were too many colors.
111
112 - the nearest_color filter (undocumented until I find a use for it)
113 leaked both temporaries passed to the API and internal buffers
114
a2791e47
TC
115 - the internal process of upgrading a paletted image to a direct
116 color image would leak a context object reference count.
117
118 - a write failure when writing to a GIF file could leak memory.
119
120 - failing to write to a 1-bit/pixel ICO image could leak memory.
121
122 - Imager no longer deliberately leaks the context object from the
123 initial thread. This was done to ensure there was always a context
124 object available, but the code that needed that now handles the
125 lack correctly,
126
e6226ce5
TC
127 - fixed some uninitialized memory usage detected by valgrind:
128
129 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
130 i_matrix_transform_bg() didn't initialize a working color value
131 if there was zero pixel coverage.
132
133 - i_ft2_cp() didn't initialize the complete color when producing an
134 intermediate image. This caused uninitialized value usage when
135 logging the color.

137Imager 1.004 - 8 Nov 2015
138============

TC
140 - Imager::Color::Table is now pre-loaded by the preload() method.
141 https://rt.cpan.org/Ticket/Display.html?id=104896
142
143 - fix an assertion triggered under perl 5.23.4.
144 Thanks to A. Sinan Unur for the report and the patch.
145
7b638aba
TC
146 - Imager->new can now be used to read raw image files.

TC
153Imager 1.003 - 12 May 2015
154============
155
0fda3cfd
TC
156 - update 1.002 release notes to include the center change for filled
157 circle drawing.
158
159 - flood_fill() would escape beyond a 4-connected space under some
160 circumstances.
161 Added many more flood_fill() tests.
162 https://rt.cpan.org/Ticket/Display.html?id=103786
163
647a47c9
TC
164Imager 1.002 - 3 Apr 2015
165============
166
334b8922
TC
167 - drawing anti-aliased filled circles is now 10 to 50 times faster
168 depending on the size of the circle.
0fda3cfd
TC
169 This also changed the center from being the center of the pixel to
170 being the top left of the pixel to match the filled arcs drawn by
171 arc().
334b8922
TC
172 https://rt.cpan.org/Ticket/Display.html?id=101682
173
174 - enhancements to polygon filling:
175
176 - added a mode parameter to control how overlapping regions behave
177
178 - added a polypolygon() method to fill more than one polygon at a
179 time
180
181 - polygon filling is now exposed through the API.
182
45c8e262
TC
183 - added colormodel(), alphachannel() and colorchannels() methods.
184 These were added for two reasons:
185
186 - a future version of Imager may allow the number of channels in
187 an image to not directly represent the color model of an image.
188 eg. a greyscale TIFF image with multiple alpha channels.
189
190 - a future version of Imager may allow an image to be read without
191 translation, for example a TIFF file that contains measurements
0fda3cfd 192 from an instrument. Currently Imager transforms the samples into
d96c4de8 193 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
194 the value back.
195
196 An untranslated image would be unusable as image data, so
197 colormodel() would return "unknown" in this case.
198
199 Similarly a CMYK image might be returned as an "unknown" color
200 model image, if the caller chooses to disable translation to
201 RGB.

203Imager 1.001 - 2 Jan 2015
204============
205
aca60e01
TC
206 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
207 Thanks to Slaven Rezic for the report and the patch.

0df260f6
TC
210 - GIF: clean-up a test file if the test for the giflib 4.2.0 file
211 version bug fails.
212
213 - fix Imager::Matrix2d::rotate()'s centre point handling
214 https://rt.cpan.org/Public/Bug/Display.html?id=99959
215

228 - update the bundled/modified Devel::CheckLib to handle the gcc-4
229 symlink on Cygwin

231Imager 1.000 - 28 Jul 2014
232============
233
234There's nothing special about Imager 1.000, it's just another release.
235
fa3dac1d
TC
236 - fix the skip check for the iolayer qr// buffer test
237
238 - improve error reporting for the iolayer test failing on a small
239 number of Win32 CPAN testers

TC
241Imager 0.99_02 - 21 Jul 2014
242==============
243
5dab5b9a
TC
244 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
245 the blue channel in the generated palette, and allow each color
246 component to be in the range 100..255 instead of just 100..254.
247 Thanks to Ralf Neubauer.
248 https://rt.cpan.org/Ticket/Display.html?id=97086
249
250 - revert "improved the XS for i_io_read() and i_io_raw_read()"
251 This caused problems with older perls and didn't provide much of a
252 performance improvement.
253
5bf25bc2 254 - support Inline 0.57 and later.
6d47a6af 255 Inline 0.57 changed the "with" interface.
5bf25bc2
TC
256 https://rt.cpan.org/Ticket/Display.html?id=97108
257
6d47a6af
TC
258 - don't define our own MAXINT macro, it conflicts with windows header
259 files and in a few places it was the wrong value to use anyway.

262Imager 0.99_01 - 29 Jun 2014
263==============
264
7b486870
TC
265 - GIF: add support for giflib 5.1.0, which added error code pointer
266 parameters to EGifCloseFile() and DGifCloseFile().
267 https://rt.cpan.org/Ticket/Display.html?id=96756
268
269 - GIF: avoid a double-free when do_write() fails.
270
28104a85 271 - fix SV type probing to work on perl before 5.12. Broken in 0.99.
ea87cee9
TC
272 https://rt.cpan.org/Ticket/Display.html?id=96761
273
df04d4b3
TC
274 - PNG: skip the benign error test before libpng 1.6.0, since the
275 error we're testing didn't exist before 1.6.0.
276 https://rt.cpan.org/Ticket/Display.html?id=94717 (continued)

TC
278Imager 0.99 - 25 Jun 2014
279===========
280
dce1523b
TC
281 - Imager::IO->new_buffer() (and hence Imager->read()'s data
282 parameter) now accepts a reference to a scalar as well as just a
283 plain scalar.
6a160bce 284 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
285
286 - Imager::IO->new_buffer() now always makes a copy of the passed in
287 buffer to avoid problems with temporary objects used for the return
288 value of SvPVbyte().
6a160bce 289 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 290
c757e211
TC
291 - improved the XS for i_io_read() and i_io_raw_read()
292 https://rt.cpan.org/Ticket/Display.html?id=92738
293
294 - load plugins from absolute paths on Android
295 Thanks to Brian Fraser.
296 https://rt.cpan.org/Ticket/Display.html?id=93272
297
6a160bce
TC
298 - added the jpeg_optimize parameter for writing JPEG files. This can
299 significantly reduce file sizes, but uses more memory and time.
300 https://rt.cpan.org/Ticket/Display.html?id=94292
301
14fd9e5d
TC
302 - the autolevels filter now works on the luminosity of the image
303 rather then working per channel. The old autolevels filter is
304 still available as "autolevels_skew".
305 https://rt.cpan.org/Ticket/Display.html?id=94413
306
75d54149
TC
307 - Imager::File::PNG now supports libpng 1.6.10.
308 1.6.10 changed CRC errors from benign errors to normal errors,
309 which broke the test which used CRC errors to check for benign
310 error support. Switched to using a 1-bit grey-scale image with a
311 palette to test for benign errors.
312 https://rt.cpan.org/Ticket/Display.html?id=94717
313

TC
314Imager 0.98 - 3 Jan 2014
315===========
316
f84f86a2
TC
317Incompatible changes:
318
319 - the return value of setpixel() has changed.
320
321 Previously the return values for undrawable pixels vs caller errors
322 changed depending on whether you used the multiple pixel calling
323 mechanism, or the single pixel mechanism.
324
325 Now:
326
327 - for an invalid parameter, such as an unknown colour, or missing
328 parameter, an empty list (or undef in scalar context) is
329 returned, and errstr() is set,
330
331 - otherwise the number of pixels drawn is returned. If none of
332 the pixels could be drawn (they were all outside the image), "0
333 but true" is returned.
334
335 https://rt.cpan.org/Ticket/Display.html?id=87650
336
337Other changes:
338
6ba09ab9
TC
339 - when drawing on an image with an alpha channel where the source
340 minimum is greater than zero, Imager would read from beyond the end
341 of a malloc() allocated buffer. In rare circumstances this could
342 lead to some of the source image not being written to the target
343 image, or possibly to a segmentation fault.
344 I don't believe this has any security concerns beyond that.
345
0d052fd9
TC
346 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
347 text drawn would be nonsense. This would also read beyond the end
348 of a malloced buffer.
349
13671b17
TC
350 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
351 truncated early.
352 https://rt.cpan.org/Ticket/Display.html?id=88993
353
d6f4e964
TC
354 - Imager::Font::Wrap no longer requires the image parameter.
355 https://rt.cpan.org/Ticket/Display.html?id=87338
356
f84f86a2
TC
357 - a documentation typo fix in Imager::Transformations
358 Thanks to Adrian Yee.
359 https://rt.cpan.org/Ticket/Display.html?id=88598
360
0179ecd6
TC
361 - Image::Probe, Imager's internal module for probing library
362 locations now searches the directories specified by LD_RUN_PATH,
363 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
364 and the corresponing s/\blib$/include/ directories for header
365 files.

376 - PNG: treat a version mismatch between headers and library as a
377 probe failure.
378 https://rt.cpan.org/Ticket/Display.html?id=86659
379
8e90f677
TC
380 - PNG: the check for benign error support is more complex than a
381 simple library version check, check for the appropriate macro.
382 Thanks for Slaven Rezic for following up on my CPAN Testers result
383 queries.

391
05c9b356
TC
392 - TIFF: handle SampleFormat = 2 by translating the signed integer
393 values to unsigned by flipping their sign bits.
394
395 Handle SampleFormat = 3 where possible.
396
397 SampleFormat is ignored for paletted images.
398
237d9e03
TC
399 Mixed SampleFormat are handled incorrectly, since libtiff returns
400 only the first SampleFormat value, and an image with both an alpha
401 channel and SampleFormat = 2 for color channels probably has a
402 different SampleFormat for the alpha channel.

face45e7 408
237d9e03 409 - Imager::Color's rgba() method now returns its values as integers
face45e7
TC
410 instead of floating point. (IV instead of NV).
411
19e9591b
TC
412 - The XS for i_map() and i_matrix_transform() now use the AV *
413 typemap instead of rolling their own.
414
75cebca8
TC
415 - The XS for DSO_call() now uses the HV * typemap instead of
416 rolling it's own.
417
0aaa8b4d
TC
418 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
419 i_gradgen() now use a new T_AVARRAY typemap that greatly
420 simplifies the XS code.
face45e7 421
ccd01d49
TC
422 - many other minor XS changes
423
face45e7 424 - some XS code formatting
a54e32ba 425
dcab59bc
TC
426 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
427 now renders in alpha-combining mode, to match antialiased output.
428 https://rt.cpan.org/Ticket/Display.html?id=73359
b482243a 429
8db7b6fa
TC
430 - add sample code and cookbook notes for drawing a blurred drop-shadow.
431
432 - add support for libpng 1.6, which changed the defaults for
433 reporting some types of error.

dc076f98
TC
436 - FT2: use gsamp/psamp() to transfer pixels from the work image to
437 the output image instead of gpix/ppix.

443Imager 0.96 - 19 May 2013
444===========
445
c2e251d9
TC
446 - rearrange Imager's test files.
447 https://rt.cpan.org/Ticket/Display.html?id=84596
448
449 - Imager::Probe::_gcc_lib_paths now forces C locale.

TC
651 - The size of rotated images is no longer rounded up so aggressively.
652 Added rounding to the linear interpolation done for rotate() and
653 matrix_transform() for 1 and 3 channel 8-bit images.
654 Adjusted the two tranlate matrices used to build the final rotation
655 matrix to use the distance between the outlier pixels rather than
656 the pixel dimensions (ie. dimension-1).
657 With all of this the output of rotate(degrees => 270) on an 8-bit
658 image exactly matches the output of rotate(right => 270).

660
ef84bb32
TC
661Other changes:
662
663 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
664 internals, those names only matter for the XS interface.
665
666 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
667 the API level compiled into a loadable module such as
668 Imager::File::GIF doesn't match that of Imager. Previously it
669 could be difficult to determine exactly which module was failing to
670 load.
671 https://rt.cpan.org/Ticket/Display.html?id=77173
672
673 - added Imager->check_file_limits() as an interface to the
674 i_int_check_image_file_limits() API.
675
676 - Imager->set_file_limits(reset => 1) now resets the limits to the
677 defaults rather than setting them all to unlimited.

685Bug fixes:

688 parameter but the prototype didn't allow for the extra parameter.
689 Corrected the prototype.
690
29b38678
TC
691 - when downconverting samples (eg. from floating point to 8 bit)
692 Imager now rounds the sample value rather than attempting to
693 allocate input values over output values equally. The old
694 behaviour had the probably surprising effect of converting a
695 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
696 2.
697 This may result in slightly different 8 or 16-bit output images.
698
e2a86bac
TC
699 - BI_BITFIELD BMP images were handled incorrectly, both in
700 incorrectly calculating the space required for the masks and in
701 processing the image data itself.
702 https://rt.cpan.org/Ticket/Display.html?id=76736
703
704 - some odd width BMP BI_RLE4 images use run lengths that run one off
705 the edge of the image. Imager now allows this, discarding the
706 extra column.
707
708 - odd length RLE4 runs in BMP images were decoded incorrectly.
709

TC
710 - pkg-config could sometimes return a library that was in a directory
711 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
712 If no -L is included in the pkg-config library information check if
713 EU::MM can find the library, and if not, search our configured
714 directories and insert that into the library flags.

717 - Imager::Probe can now probe for libraries with dependent libraries,
718 common for static linking, eg. libpng requires libz.
719 https://rt.cpan.org/Ticket/Display.html?id=74043
720
721 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
722
723 - added alternative probe configurations that try to link libz, to
724 handle a statically linked libpng.
725 https://rt.cpan.org/Ticket/Display.html?id=74043
726
727 - if a probe includes testcode, Imager::Probe now checks that code as
728 part of the process of checking each configuration rather than as a
729 post test of the found configuration. This allows alternate
730 configurations to be checked if a matching but non-working
731 configuration is found.

807 - setsamples() is now a true complement to getsamples() - it can
808 write 8-bit or floating point samples from a scalar or array
809 reference. This adds i_psamp() and i_psampf() to the C level API.
810
811 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have

967 - add simple tests for the Imager::Test test_image generators
968

TC
969 - io_glue I/O buffering re-work:
970
971 - reorganize io_glue to do it's own buffering by default
972
973 - the unbuffered functions are available as i_io_raw_read() (or
974 raw_read() from perl) etc but are not recommended for typical
975 use.
976
977 - use the new i_io_peekn() when checking for file magic to avoid
978 seek, allowing Imager to detect the file type and read the file
979 from an unseekable stream (for formats that don't use random
980 access)
981
982 - added several new I/O layer API functions.
983
984 - fix the TGA performance problem, most noticably on Win32
985 https://rt.cpan.org/Ticket/Display.html?id=70037
986
987 - TIFF now uses wrapper functions of the correct types to avoid casts
988 https://rt.cpan.org/Ticket/Display.html?id=69912
989
990 - the callback IO object did its own buffering, controlled by the
991 maxbuffer parameter supplied to the read() and write() methods.
992 This buffering has been removed, to avoid redundancy with the
993 common io_glue buffering. This also avoids a bug in that code
994 which could rarely pass a zero length to the read callback and
995 then panic about the result.
996
997 - the callback IO object now tests the result of calling the close
998 callback, which should return true for success.
999
1000 - the PNM reader did its own buffering. This buffering has been
1001 removed to avoid redundancy with the common io_glue buffering.
1002
1003 - previously the read handlers for fd and callback I/O layers would
1004 call the underlying interface (POSIX read or your supplied callback)
1005 until it filled the buffer. It now only makes one call.
1006
1007 - added public constructors for I/O layer objects (see Imager::IO)
1008
1009 - all core file handlers now use the i_io_foo() wrappers to gain
1010 access to buffered I/O rather than calling the I/O layer
1011 callbacks directly.
1012
1013 - all core file handlers now check for error on close.
1014
1015 - Backward compatibility: if you hava custom file handlers, you can
1016 use i_io_write() etc since they're available as macros in older
1017 versions of Imager.
1018
1019 - eliminate the final remnants of io_glue_commit_types().
1020
1021 - bump IMAGER_API_VERSION, since the above may break assumptions.
1022
1023 - removed the long unused i_gen_reader() and i_gen_writer() utility
1024 functions.

1086
1087Development release as a sanity check for the types re-work.
8d14daab
TC
1088
1089Massive types re-work:
1090
1091 - the type used internally for pixel co-ordinates and image sizes is
1092 now 64-bit on 64-bit platforms (at least sane ones).
1093
1094 - size_t is now used consistently for memory block sizes.
1095
1096 - since this changes the binary interface, the Imager API version has
1097 been incremented. Any module that uses the API will need to be
1098 rebuilt. In most cases that will be enough, but calls to any APIs
1099 that take a pointer to image sizes may need source changes.
1100
1101 - you should be able to create very large images on 64-bit systems,
1102 if you have enough memory. Successfully created a 32768 x 49192 x
1103 3 channel image, filled with a tiled image and scaled it. The
1104 unscaled image was also successfully saved to a JPEG.
1105
1106 - check the image size before attempting to write BMP, GIF, JPEG,
1107 PNG, SGI, TGA, TIFF images.
1108
1109 - correctly handle reading TGA images over 32767 pixels wide or tall.
1110
1111Incidental changes:
1112
1113 - the gif_left and gif_top tags are now clamped to non-negative
1114 values when writing a GIF image.
1115
1116 - removed dead callback read/write code
1117
1118The default maximum memory size when reading files is now 1G.

1767 - paste() and rubthrough() now adapt the source image data to the
1768 destination, so you can now safely paste/rubthrough from greyscale
1769 images to color images or back, or from alpha channel images to
1770 noalpha channels or back.
1771 https://rt.cpan.org/Ticket/Display.html?id=30908
1772
1773 - rubthrough() now falls back to pasting when the source doesn't have
1774 an alpha channel. This effectively treats the source as having a
1775 max alpha channel, the right thing to do.
1776 http://rt.cpan.org/Ticket/Display.html?id=29944
1777
1778 - re-worked most of the area filling code to use a common set of
1779 functions when filling.
1780 Corrected normal combine mode.
1781 Rewrote most of the combine modes to match the way the SVG draft
1782 defines them with respect to a translucent source and destination.
1783 Added tests for translucent source and destination.
1784 Added tests to check 8-bit/sample and double/sample combines work
1785 similarly.

1821 - some TGA images weren't being detected correctly as TGA images
1822 https://rt.cpan.org/Ticket/Display.html?id=32925
1823
1824 - handling of the left-over bit for 16-bit/pixel TGA images has been
1825 changed to match the behaviour of the GIMP. Previously the bit
1826 being set was treated as an opaque pixel, but one user reported a
1827 problem with loading such an image. I haven't been able to find any
1828 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1829 I'll match it's behaviour. See issue 114913 in the GIMP's
1830 bugzilla.

2181 that's the default build name for zlib on Win32.
2182 http://rt.cpan.org/Ticket/Display.html?id=23064
2183
2184 - search $Config{incpath} for headers too, which we should have been
2185 doing all along.
2186
2187Win32 font driver fixes:
2188
2189 - the global descent value from bounding box was the wrong sign
2190 http://www.cpanforum.com/threads/3276
2191
2192 - if the first or last glyph overflowed the left or right side of the
2193 advance width they would be clipped

2196Imager 0.54 - 14 Sep 2006
2197===========
2198
2199This is primarily a feature release:
2200
2201 - a new qtype value 'mixing' has been added to the scale()
2202 method. This is faster than 'normal', slower than 'preview'. This
2203 is based on the method used by pnmscale, and seems to produce less
2204 blurry results than normal.
2205 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2206
2207 - the rubthrough() method can now render onto images with an alpha
2208 channel.
2209 http://rt.cpan.org/Ticket/Display.html?id=20678
2210
2211 - the read_multi() method now falls back to calling doing a single
2212 image read via the read() method and write_multi() will now fall
2213 back to calling write() if a single image is supplied. This means
2214 you can simply call the read_multi() or write_multi() functions
2215 without having to check if the type is formatted by that method.
2216 http://rt.cpan.org/Ticket/Display.html?id=19457
2217 http://rt.cpan.org/Ticket/Display.html?id=19458
2218
2219 - the GIF loop extension can now be written. If you don't have
2220 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2221 should upgrade.
2222 http://rt.cpan.org/Ticket/Display.html?id=21185
2223
2224 - getscanline() and setscanline() can now read/write palette index
2225 based data from/to the image for paletted images, by setting type to
2226 'index'.
2227 http://rt.cpan.org/Ticket/Display.html?id=20338
2228
2229 - we no longer hassle you to disable GIF support
2230 http://rt.cpan.org/Ticket/Display.html?id=20687
2231
2232 - minor documentation fixes
2233
2234
2235Imager 0.53 - 26 Jul 2006
2236===========
2237
2238This is a bugfix release.
2239
2240Some test code was left in a code path not covered by the test
2241suite. A test was added to cover this code path and the test code was
2242removed.

2244
2245
2246Imager 0.52 - 25 Jul 2006
2247===========
2248
2249This is primarily a feature release, but contains a fair few bug
2250fixes, new features:
2251
2252 - ability to read and write MS Windows ICO and CUR files
2253
2254 - you can now add file format plugins to support new file formats
2255
2256 - add POD coverage tests
2257
2258 - setcolors() and addcolors() now accept color names and so on
2259 instead of requiring Imager::Color objects.
2260 http://rt.cpan.org/Ticket/Display.html?id=20056
2261
2262 - flood_fill() can now fill to a specified border color instead of
2263 just to the area the same color as the seed.
2264 http://rt.cpan.org/Ticket/Display.html?id=19618
2265
2266
2267Bug fixes:
2268
2269 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2270 calculating the advance width.
2271 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2272
2273 - bounding_box for the T1 driver wasn't including leading and
2274 trailing spaces in the bounding box as the other drivers did, it also
2275 produced strange results for empty strings or strings containing only
2276 spaces
2277
2278 - when reading CMYK jpeg images they were being transferred to the
2279 image object as is, producing a four channel image. It only looked ok
2280 due to an old still unfixed Photoshop bug. We now convert from the
2281 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2282 http://rt.cpan.org/Ticket/Display.html?id=20416
2283
2284 - reading a CYMK TIFF would result in a 4 channel image, reading any
2285 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2286 result in an error.
2287 http://rt.cpan.org/Ticket/Display.html?id=20415
2288
2289 - added /usr/local/include to the default include search path, since
2290 we were already searching /usr/local/lib for libraries.
2291
2292And various minor fixes and documentation updates.
2293
2294
