12Imager 1.006 - 26 Aug 2017
13============
14
ba7ddbae
TC
15 - the internal i_errors() function now correctly allocates the stack
16 space needed for its result.
17 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
18
19 - t/100-base/020-color.t now uses Imager::Test's test functions
20 instead of its own.
21 https://rt.cpan.org/Ticket/Display.html?id=111993
22
344dda51
TC
23 - write_multi() now returns an error result (a false value) if called
24 with a non-(Imager image object). Previously it would typically
25 crash.
26 https://rt.cpan.org/Ticket/Display.html?id=117878
27
28 - improve the documentation of the jpegquality parameter when
29 writing JPEG files.
30
31 - add code to mitigate CVE-2016-1238, Imager will no longer search the
32 default current directory entry in @INC when searching for file
33 format support modules.

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

44Imager 1.004_004 - 15 Apr 2016
45================
46
9c45cc49
TC
47 - test that the ivdformat from Config is correct and look for a valid
48 one if it isn't.
49 For the strange Win32 failures.
50
51 - fix a copy and paste error in pod in samples/samp-form.cgi

53Imager 1.004_003 - 23 Mar 2016
54================
55
bd2d657d
TC
56 - add some extra error reporting to the I/O layers tests, this might
57 help catch a failure seen on Win32.

61================
62
735b3e7b
TC
63 - don't use the seek() method on opened() handles in
64 t/200-file/400-basic.t. In older versions of perl such handles are
65 only IO::Handle objects, not IO::File, and don't have a seek()
66 method.

68Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
69================
70
08914ed1
TC
71 - re-work the t/200-file/400-basic.t to correctly handle failures
72 It's custom ok() function didn't have a prototype and didn't use scalar().
73 This caused ok() to use the note instead of the value being tested when
74 the method called returned an empty list. For an example of the problem
e6226ce5 75 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 76
a2791e47
TC
77 - remove some noise from when Imager tried to work with bugs in old
78 versions of giflib. I can't do much about the new bugs.
08914ed1 79
e6226ce5
TC
80 - the new autolevels filter (Imager 0.99) used an integer for the
81 sample scaling factor which caused the top output level to be too
82 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
83 https://rt.cpan.org/Ticket/Display.html?id=111871
84
e6226ce5 85 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
86 minimum and maximum luminance from the histogram. This slightly
87 reduced the contrast of the output image.
88 https://rt.cpan.org/Ticket/Display.html?id=111871
89
90 - the new autolevels filter now uses a lookup table for 8-bit images
91 to avoid a floating point multiply for each sample.
92 https://rt.cpan.org/Ticket/Display.html?id=111871
93
e6226ce5
TC
94 - fixed several memory leaks detected by valgrind:
95
96 - addcolors() leaked the temporary array of colors supplied to the
97 internal API
98
99 - make_palette() leaked the temporary image array (not the images
100 themselves) passed to the internal API.
101
102 - combine()/i_combine() leaked its working row buffers
103
104 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
105 buffer if there were too many colors
106
107 - getcolorcount()/i_count_colors() leaked the sample buffer if
108 there were too many colors.
109
110 - the nearest_color filter (undocumented until I find a use for it)
111 leaked both temporaries passed to the API and internal buffers
112
a2791e47
TC
113 - the internal process of upgrading a paletted image to a direct
114 color image would leak a context object reference count.
115
116 - a write failure when writing to a GIF file could leak memory.
117
118 - failing to write to a 1-bit/pixel ICO image could leak memory.
119
120 - Imager no longer deliberately leaks the context object from the
121 initial thread. This was done to ensure there was always a context
122 object available, but the code that needed that now handles the
123 lack correctly,
124
e6226ce5
TC
125 - fixed some uninitialized memory usage detected by valgrind:
126
127 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
128 i_matrix_transform_bg() didn't initialize a working color value
129 if there was zero pixel coverage.
130
131 - i_ft2_cp() didn't initialize the complete color when producing an
132 intermediate image. This caused uninitialized value usage when
133 logging the color.

135Imager 1.004 - 8 Nov 2015
136============

TC
138 - Imager::Color::Table is now pre-loaded by the preload() method.
139 https://rt.cpan.org/Ticket/Display.html?id=104896
140
141 - fix an assertion triggered under perl 5.23.4.
142 Thanks to A. Sinan Unur for the report and the patch.

TC
144 - Imager->new can now be used to read raw image files.

TC
151Imager 1.003 - 12 May 2015
152============
153
0fda3cfd
TC
154 - update 1.002 release notes to include the center change for filled
155 circle drawing.
156
157 - flood_fill() would escape beyond a 4-connected space under some
158 circumstances.
159 Added many more flood_fill() tests.

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

202============
203
aca60e01
TC
204 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
205 Thanks to Slaven Rezic for the report and the patch.

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

229Imager 1.000 - 28 Jul 2014
230============
231
232There's nothing special about Imager 1.000, it's just another release.
233
fa3dac1d
TC
234 - fix the skip check for the iolayer qr// buffer test
235
236 - improve error reporting for the iolayer test failing on a small
237 number of Win32 CPAN testers

239Imager 0.99_02 - 21 Jul 2014
240==============
241
5dab5b9a
TC
242 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
243 the blue channel in the generated palette, and allow each color
244 component to be in the range 100..255 instead of just 100..254.
245 Thanks to Ralf Neubauer.
246 https://rt.cpan.org/Ticket/Display.html?id=97086
247
248 - revert "improved the XS for i_io_read() and i_io_raw_read()"
249 This caused problems with older perls and didn't provide much of a
250 performance improvement.
251
5bf25bc2 252 - support Inline 0.57 and later.
6d47a6af 253 Inline 0.57 changed the "with" interface.
5bf25bc2
TC
254 https://rt.cpan.org/Ticket/Display.html?id=97108
255
6d47a6af
TC
256 - don't define our own MAXINT macro, it conflicts with windows header
257 files and in a few places it was the wrong value to use anyway.

260Imager 0.99_01 - 29 Jun 2014
261==============
262
7b486870
TC
263 - GIF: add support for giflib 5.1.0, which added error code pointer
264 parameters to EGifCloseFile() and DGifCloseFile().
265 https://rt.cpan.org/Ticket/Display.html?id=96756
266
267 - GIF: avoid a double-free when do_write() fails.
268
28104a85 269 - fix SV type probing to work on perl before 5.12. Broken in 0.99.

271
df04d4b3
TC
272 - PNG: skip the benign error test before libpng 1.6.0, since the
273 error we're testing didn't exist before 1.6.0.

276Imager 0.99 - 25 Jun 2014
277===========
278
dce1523b
TC
279 - Imager::IO->new_buffer() (and hence Imager->read()'s data
280 parameter) now accepts a reference to a scalar as well as just a
281 plain scalar.
6a160bce 282 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
283
284 - Imager::IO->new_buffer() now always makes a copy of the passed in
285 buffer to avoid problems with temporary objects used for the return
286 value of SvPVbyte().
6a160bce 287 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 288
c757e211
TC
289 - improved the XS for i_io_read() and i_io_raw_read()
290 https://rt.cpan.org/Ticket/Display.html?id=92738
291
292 - load plugins from absolute paths on Android
293 Thanks to Brian Fraser.
294 https://rt.cpan.org/Ticket/Display.html?id=93272
295
6a160bce
TC
296 - added the jpeg_optimize parameter for writing JPEG files. This can
297 significantly reduce file sizes, but uses more memory and time.
298 https://rt.cpan.org/Ticket/Display.html?id=94292
299
14fd9e5d
TC
300 - the autolevels filter now works on the luminosity of the image
301 rather then working per channel. The old autolevels filter is
302 still available as "autolevels_skew".
303 https://rt.cpan.org/Ticket/Display.html?id=94413
304
75d54149
TC
305 - Imager::File::PNG now supports libpng 1.6.10.
306 1.6.10 changed CRC errors from benign errors to normal errors,
307 which broke the test which used CRC errors to check for benign
308 error support. Switched to using a 1-bit grey-scale image with a
309 palette to test for benign errors.
310 https://rt.cpan.org/Ticket/Display.html?id=94717

TC
312Imager 0.98 - 3 Jan 2014
313===========
314
f84f86a2
TC
315Incompatible changes:
316
317 - the return value of setpixel() has changed.
318
319 Previously the return values for undrawable pixels vs caller errors
320 changed depending on whether you used the multiple pixel calling
321 mechanism, or the single pixel mechanism.
322
323 Now:
324
325 - for an invalid parameter, such as an unknown colour, or missing
326 parameter, an empty list (or undef in scalar context) is
327 returned, and errstr() is set,
328
329 - otherwise the number of pixels drawn is returned. If none of
330 the pixels could be drawn (they were all outside the image), "0
331 but true" is returned.
332
333 https://rt.cpan.org/Ticket/Display.html?id=87650
334
335Other changes:
336
6ba09ab9
TC
337 - when drawing on an image with an alpha channel where the source
338 minimum is greater than zero, Imager would read from beyond the end
339 of a malloc() allocated buffer. In rare circumstances this could
340 lead to some of the source image not being written to the target
341 image, or possibly to a segmentation fault.
342 I don't believe this has any security concerns beyond that.
343
0d052fd9
TC
344 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
345 text drawn would be nonsense. This would also read beyond the end
346 of a malloced buffer.
347
13671b17
TC
348 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
349 truncated early.
350 https://rt.cpan.org/Ticket/Display.html?id=88993
351
d6f4e964
TC
352 - Imager::Font::Wrap no longer requires the image parameter.
353 https://rt.cpan.org/Ticket/Display.html?id=87338
354
f84f86a2
TC
355 - a documentation typo fix in Imager::Transformations
356 Thanks to Adrian Yee.
357 https://rt.cpan.org/Ticket/Display.html?id=88598
358
0179ecd6
TC
359 - Image::Probe, Imager's internal module for probing library
360 locations now searches the directories specified by LD_RUN_PATH,
361 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
362 and the corresponing s/\blib$/include/ directories for header
363 files.

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

389
05c9b356
TC
390 - TIFF: handle SampleFormat = 2 by translating the signed integer
391 values to unsigned by flipping their sign bits.
392
393 Handle SampleFormat = 3 where possible.
394
395 SampleFormat is ignored for paletted images.
396
237d9e03
TC
397 Mixed SampleFormat are handled incorrectly, since libtiff returns
398 only the first SampleFormat value, and an image with both an alpha
399 channel and SampleFormat = 2 for color channels probably has a
400 different SampleFormat for the alpha channel.

face45e7 406
237d9e03 407 - Imager::Color's rgba() method now returns its values as integers
face45e7
TC
408 instead of floating point. (IV instead of NV).
409
19e9591b
TC
410 - The XS for i_map() and i_matrix_transform() now use the AV *
411 typemap instead of rolling their own.
412
75cebca8
TC
413 - The XS for DSO_call() now uses the HV * typemap instead of
414 rolling it's own.
415
0aaa8b4d
TC
416 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
417 i_gradgen() now use a new T_AVARRAY typemap that greatly
418 simplifies the XS code.
face45e7 419
ccd01d49
TC
420 - many other minor XS changes
421
face45e7 422 - some XS code formatting
a54e32ba 423
dcab59bc
TC
424 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
425 now renders in alpha-combining mode, to match antialiased output.

TC
444 - rearrange Imager's test files.
445 https://rt.cpan.org/Ticket/Display.html?id=84596
446
447 - Imager::Probe::_gcc_lib_paths now forces C locale.
448 A sufficiently recent gcc prints localized keys for the search
449 paths, which avoids that localization.

613 The giflib API Imager uses doesn't have a mechanism to set the
614 header version in 5.0.0.

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

658
ef84bb32
TC
659Other changes:
660
661 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
662 internals, those names only matter for the XS interface.
663
664 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
665 the API level compiled into a loadable module such as
666 Imager::File::GIF doesn't match that of Imager. Previously it
667 could be difficult to determine exactly which module was failing to
668 load.
669 https://rt.cpan.org/Ticket/Display.html?id=77173
670
671 - added Imager->check_file_limits() as an interface to the
672 i_int_check_image_file_limits() API.
673
674 - Imager->set_file_limits(reset => 1) now resets the limits to the
675 defaults rather than setting them all to unlimited.

683Bug fixes:

686 parameter but the prototype didn't allow for the extra parameter.
687 Corrected the prototype.
688
29b38678
TC
689 - when downconverting samples (eg. from floating point to 8 bit)
690 Imager now rounds the sample value rather than attempting to
691 allocate input values over output values equally. The old
692 behaviour had the probably surprising effect of converting a
693 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
694 2.
695 This may result in slightly different 8 or 16-bit output images.
696
e2a86bac
TC
697 - BI_BITFIELD BMP images were handled incorrectly, both in
698 incorrectly calculating the space required for the masks and in
699 processing the image data itself.
700 https://rt.cpan.org/Ticket/Display.html?id=76736
701
702 - some odd width BMP BI_RLE4 images use run lengths that run one off
703 the edge of the image. Imager now allows this, discarding the
704 extra column.
705
706 - odd length RLE4 runs in BMP images were decoded incorrectly.
707
82eb0687
TC
708 - pkg-config could sometimes return a library that was in a directory
709 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
710 If no -L is included in the pkg-config library information check if
711 EU::MM can find the library, and if not, search our configured
712 directories and insert that into the library flags.

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

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

TC
967 - io_glue I/O buffering re-work:
968
969 - reorganize io_glue to do it's own buffering by default
970
971 - the unbuffered functions are available as i_io_raw_read() (or
972 raw_read() from perl) etc but are not recommended for typical
973 use.
974
975 - use the new i_io_peekn() when checking for file magic to avoid
976 seek, allowing Imager to detect the file type and read the file
977 from an unseekable stream (for formats that don't use random
978 access)
979
980 - added several new I/O layer API functions.
981
982 - fix the TGA performance problem, most noticably on Win32
983 https://rt.cpan.org/Ticket/Display.html?id=70037
984
985 - TIFF now uses wrapper functions of the correct types to avoid casts
986 https://rt.cpan.org/Ticket/Display.html?id=69912
987
988 - the callback IO object did its own buffering, controlled by the
989 maxbuffer parameter supplied to the read() and write() methods.
990 This buffering has been removed, to avoid redundancy with the
991 common io_glue buffering. This also avoids a bug in that code
992 which could rarely pass a zero length to the read callback and
993 then panic about the result.
994
995 - the callback IO object now tests the result of calling the close
996 callback, which should return true for success.
997
998 - the PNM reader did its own buffering. This buffering has been
999 removed to avoid redundancy with the common io_glue buffering.
1000
1001 - previously the read handlers for fd and callback I/O layers would
1002 call the underlying interface (POSIX read or your supplied callback)
1003 until it filled the buffer. It now only makes one call.
1004
1005 - added public constructors for I/O layer objects (see Imager::IO)
1006
1007 - all core file handlers now use the i_io_foo() wrappers to gain
1008 access to buffered I/O rather than calling the I/O layer
1009 callbacks directly.
1010
1011 - all core file handlers now check for error on close.
1012
1013 - Backward compatibility: if you hava custom file handlers, you can
1014 use i_io_write() etc since they're available as macros in older
1015 versions of Imager.
1016
1017 - eliminate the final remnants of io_glue_commit_types().
1018
1019 - bump IMAGER_API_VERSION, since the above may break assumptions.
1020
1021 - removed the long unused i_gen_reader() and i_gen_writer() utility
1022 functions.

1084
1085Development release as a sanity check for the types re-work.
8d14daab
TC
1086
1087Massive types re-work:
1088
1089 - the type used internally for pixel co-ordinates and image sizes is
1090 now 64-bit on 64-bit platforms (at least sane ones).
1091
1092 - size_t is now used consistently for memory block sizes.
1093
1094 - since this changes the binary interface, the Imager API version has
1095 been incremented. Any module that uses the API will need to be
1096 rebuilt. In most cases that will be enough, but calls to any APIs
1097 that take a pointer to image sizes may need source changes.
1098
1099 - you should be able to create very large images on 64-bit systems,
1100 if you have enough memory. Successfully created a 32768 x 49192 x
1101 3 channel image, filled with a tiled image and scaled it. The
1102 unscaled image was also successfully saved to a JPEG.
1103
1104 - check the image size before attempting to write BMP, GIF, JPEG,
1105 PNG, SGI, TGA, TIFF images.
1106
1107 - correctly handle reading TGA images over 32767 pixels wide or tall.
1108
1109Incidental changes:
1110
1111 - the gif_left and gif_top tags are now clamped to non-negative
1112 values when writing a GIF image.
1113
1114 - removed dead callback read/write code
1115
1116The default maximum memory size when reading files is now 1G.

1767 images to color images or back, or from alpha channel images to
1768 noalpha channels or back.
1769 https://rt.cpan.org/Ticket/Display.html?id=30908
1770
1771 - rubthrough() now falls back to pasting when the source doesn't have
1772 an alpha channel. This effectively treats the source as having a
1773 max alpha channel, the right thing to do.
1774 http://rt.cpan.org/Ticket/Display.html?id=29944

1776 - re-worked most of the area filling code to use a common set of

1779 Rewrote most of the combine modes to match the way the SVG draft
1780 defines them with respect to a translucent source and destination.
1781 Added tests for translucent source and destination.
1782 Added tests to check 8-bit/sample and double/sample combines work
1783 similarly.

1819 - some TGA images weren't being detected correctly as TGA images
1820 https://rt.cpan.org/Ticket/Display.html?id=32925
1821
1822 - handling of the left-over bit for 16-bit/pixel TGA images has been
1823 changed to match the behaviour of the GIMP. Previously the bit
1824 being set was treated as an opaque pixel, but one user reported a
1825 problem with loading such an image. I haven't been able to find any
1826 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1827 I'll match it's behaviour. See issue 114913 in the GIMP's
1828 bugzilla.

2180 http://rt.cpan.org/Ticket/Display.html?id=23064
2181
2182 - search $Config{incpath} for headers too, which we should have been
2183 doing all along.
2184
2185Win32 font driver fixes:
2186
2187 - the global descent value from bounding box was the wrong sign
2188 http://www.cpanforum.com/threads/3276
2189
2190 - if the first or last glyph overflowed the left or right side of the
2191 advance width they would be clipped
2192
2193
2194Imager 0.54 - 14 Sep 2006
2195===========
2196
2197This is primarily a feature release:
2198
2199 - a new qtype value 'mixing' has been added to the scale()
2200 method. This is faster than 'normal', slower than 'preview'. This
2201 is based on the method used by pnmscale, and seems to produce less
2202 blurry results than normal.
2203 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2204
2205 - the rubthrough() method can now render onto images with an alpha
2206 channel.
2207 http://rt.cpan.org/Ticket/Display.html?id=20678
2208
2209 - the read_multi() method now falls back to calling doing a single
2210 image read via the read() method and write_multi() will now fall
2211 back to calling write() if a single image is supplied. This means
2212 you can simply call the read_multi() or write_multi() functions
2213 without having to check if the type is formatted by that method.
2214 http://rt.cpan.org/Ticket/Display.html?id=19457
2215 http://rt.cpan.org/Ticket/Display.html?id=19458
2216
2217 - the GIF loop extension can now be written. If you don't have
2218 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2219 should upgrade.
2220 http://rt.cpan.org/Ticket/Display.html?id=21185
2221
2222 - getscanline() and setscanline() can now read/write palette index
2223 based data from/to the image for paletted images, by setting type to
2224 'index'.
2225 http://rt.cpan.org/Ticket/Display.html?id=20338
2226
2227 - we no longer hassle you to disable GIF support
2228 http://rt.cpan.org/Ticket/Display.html?id=20687
2229
2230 - minor documentation fixes
2231
2232
2233Imager 0.53 - 26 Jul 2006
2234===========
2235
2236This is a bugfix release.
2237
2238Some test code was left in a code path not covered by the test
2239suite. A test was added to cover this code path and the test code was
2240removed.
2241http://rt.cpan.org/Public/Bug/Display.html?id=20705
2242
2243
2244Imager 0.52 - 25 Jul 2006
2245===========
2246
2247This is primarily a feature release, but contains a fair few bug
2248fixes, new features:
2249
2250 - ability to read and write MS Windows ICO and CUR files
2251
2252 - you can now add file format plugins to support new file formats
2253
2254 - add POD coverage tests
2255
2256 - setcolors() and addcolors() now accept color names and so on
2257 instead of requiring Imager::Color objects.
2258 http://rt.cpan.org/Ticket/Display.html?id=20056
2259
2260 - flood_fill() can now fill to a specified border color instead of
2261 just to the area the same color as the seed.
2262 http://rt.cpan.org/Ticket/Display.html?id=19618
2263
2264
2265Bug fixes:
2266
2267 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2268 calculating the advance width.
2269 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2270
2271 - bounding_box for the T1 driver wasn't including leading and
2272 trailing spaces in the bounding box as the other drivers did, it also
2273 produced strange results for empty strings or strings containing only
2274 spaces
2275
2276 - when reading CMYK jpeg images they were being transferred to the
2277 image object as is, producing a four channel image. It only looked ok
2278 due to an old still unfixed Photoshop bug. We now convert from the
2279 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2280 http://rt.cpan.org/Ticket/Display.html?id=20416
2281
2282 - reading a CYMK TIFF would result in a 4 channel image, reading any
2283 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2284 result in an error.
2285 http://rt.cpan.org/Ticket/Display.html?id=20415
2286
2287 - added /usr/local/include to the default include search path, since
2288 we were already searching /usr/local/lib for libraries.
2289
2290And various minor fixes and documentation updates.
2291
2292

2300 - fix mis-processing of the src_maxx and src_maxy parameters of the
