3 - test that the ivdformat from Config is correct and look for a valid
4 one if it isn't.
5 For the strange Win32 failures.

10================
11
bd2d657d
TC
12 - add some extra error reporting to the I/O layers tests, this might
13 help catch a failure seen on Win32.

17================

TC
19 - don't use the seek() method on opened() handles in
20 t/200-file/400-basic.t. In older versions of perl such handles are
21 only IO::Handle objects, not IO::File, and don't have a seek()
22 method.

24Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
25================
26
08914ed1
TC
27 - re-work the t/200-file/400-basic.t to correctly handle failures
28 It's custom ok() function didn't have a prototype and didn't use scalar().
29 This caused ok() to use the note instead of the value being tested when
30 the method called returned an empty list. For an example of the problem
e6226ce5 31 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 32
a2791e47
TC
33 - remove some noise from when Imager tried to work with bugs in old
34 versions of giflib. I can't do much about the new bugs.
08914ed1 35
e6226ce5
TC
36 - the new autolevels filter (Imager 0.99) used an integer for the
37 sample scaling factor which caused the top output level to be too
38 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
39 https://rt.cpan.org/Ticket/Display.html?id=111871
40
e6226ce5 41 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
42 minimum and maximum luminance from the histogram. This slightly
43 reduced the contrast of the output image.
44 https://rt.cpan.org/Ticket/Display.html?id=111871
45
46 - the new autolevels filter now uses a lookup table for 8-bit images
47 to avoid a floating point multiply for each sample.
48 https://rt.cpan.org/Ticket/Display.html?id=111871
49
e6226ce5
TC
50 - fixed several memory leaks detected by valgrind:
51
52 - addcolors() leaked the temporary array of colors supplied to the
53 internal API
54
55 - make_palette() leaked the temporary image array (not the images
56 themselves) passed to the internal API.
57
58 - combine()/i_combine() leaked its working row buffers
59
60 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
61 buffer if there were too many colors
62
63 - getcolorcount()/i_count_colors() leaked the sample buffer if
64 there were too many colors.
65
66 - the nearest_color filter (undocumented until I find a use for it)
67 leaked both temporaries passed to the API and internal buffers
68
a2791e47
TC
69 - the internal process of upgrading a paletted image to a direct
70 color image would leak a context object reference count.
71
72 - a write failure when writing to a GIF file could leak memory.
73
74 - failing to write to a 1-bit/pixel ICO image could leak memory.
75
76 - Imager no longer deliberately leaks the context object from the
77 initial thread. This was done to ensure there was always a context
78 object available, but the code that needed that now handles the
79 lack correctly,
80
e6226ce5
TC
81 - fixed some uninitialized memory usage detected by valgrind:
82
83 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
84 i_matrix_transform_bg() didn't initialize a working color value
85 if there was zero pixel coverage.
86
87 - i_ft2_cp() didn't initialize the complete color when producing an
88 intermediate image. This caused uninitialized value usage when
89 logging the color.

108============
109
0fda3cfd
TC
110 - update 1.002 release notes to include the center change for filled
111 circle drawing.
112
113 - flood_fill() would escape beyond a 4-connected space under some
114 circumstances.
115 Added many more flood_fill() tests.

TC
118Imager 1.002 - 3 Apr 2015
119============
120
334b8922
TC
121 - drawing anti-aliased filled circles is now 10 to 50 times faster
122 depending on the size of the circle.
0fda3cfd
TC
123 This also changed the center from being the center of the pixel to
124 being the top left of the pixel to match the filled arcs drawn by
125 arc().
334b8922
TC
126 https://rt.cpan.org/Ticket/Display.html?id=101682
127
128 - enhancements to polygon filling:
129
130 - added a mode parameter to control how overlapping regions behave
131
132 - added a polypolygon() method to fill more than one polygon at a
133 time
134
135 - polygon filling is now exposed through the API.
136
45c8e262
TC
137 - added colormodel(), alphachannel() and colorchannels() methods.
138 These were added for two reasons:
139
140 - a future version of Imager may allow the number of channels in
141 an image to not directly represent the color model of an image.
142 eg. a greyscale TIFF image with multiple alpha channels.
143
144 - a future version of Imager may allow an image to be read without
145 translation, for example a TIFF file that contains measurements
0fda3cfd 146 from an instrument. Currently Imager transforms the samples into
45c8e262
TC
147 the range 0.0 ... 1.0 which may means the user has to translates
148 the value back.
149
150 An untranslated image would be unusable as image data, so
151 colormodel() would return "unknown" in this case.
152
153 Similarly a CMYK image might be returned as an "unknown" color
154 model image, if the caller chooses to disable translation to
155 RGB.

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

188There's nothing special about Imager 1.000, it's just another release.
189
fa3dac1d
TC
190 - fix the skip check for the iolayer qr// buffer test
191

196==============
197
5dab5b9a
TC
198 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
199 the blue channel in the generated palette, and allow each color
200 component to be in the range 100..255 instead of just 100..254.
201 Thanks to Ralf Neubauer.
202 https://rt.cpan.org/Ticket/Display.html?id=97086
203
204 - revert "improved the XS for i_io_read() and i_io_raw_read()"
205 This caused problems with older perls and didn't provide much of a
206 performance improvement.
207
5bf25bc2 208 - support Inline 0.57 and later.
6d47a6af 209 Inline 0.57 changed the "with" interface.

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

TC
219 - GIF: add support for giflib 5.1.0, which added error code pointer
220 parameters to EGifCloseFile() and DGifCloseFile().
221 https://rt.cpan.org/Ticket/Display.html?id=96756
222
223 - GIF: avoid a double-free when do_write() fails.
224
28104a85 225 - fix SV type probing to work on perl before 5.12. Broken in 0.99.

228 - PNG: skip the benign error test before libpng 1.6.0, since the
229 error we're testing didn't exist before 1.6.0.

232Imager 0.99 - 25 Jun 2014
233===========
234
dce1523b
TC
235 - Imager::IO->new_buffer() (and hence Imager->read()'s data
236 parameter) now accepts a reference to a scalar as well as just a
237 plain scalar.
6a160bce 238 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
239
240 - Imager::IO->new_buffer() now always makes a copy of the passed in
241 buffer to avoid problems with temporary objects used for the return
242 value of SvPVbyte().
6a160bce 243 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 244
c757e211
TC
245 - improved the XS for i_io_read() and i_io_raw_read()
246 https://rt.cpan.org/Ticket/Display.html?id=92738
247
248 - load plugins from absolute paths on Android
249 Thanks to Brian Fraser.
250 https://rt.cpan.org/Ticket/Display.html?id=93272
251
6a160bce
TC
252 - added the jpeg_optimize parameter for writing JPEG files. This can
253 significantly reduce file sizes, but uses more memory and time.
254 https://rt.cpan.org/Ticket/Display.html?id=94292
255
14fd9e5d
TC
256 - the autolevels filter now works on the luminosity of the image
257 rather then working per channel. The old autolevels filter is
258 still available as "autolevels_skew".
259 https://rt.cpan.org/Ticket/Display.html?id=94413
260
75d54149
TC
261 - Imager::File::PNG now supports libpng 1.6.10.
262 1.6.10 changed CRC errors from benign errors to normal errors,
263 which broke the test which used CRC errors to check for benign
264 error support. Switched to using a 1-bit grey-scale image with a
265 palette to test for benign errors.

TC
268Imager 0.98 - 3 Jan 2014
269===========
270
f84f86a2
TC
271Incompatible changes:
272
273 - the return value of setpixel() has changed.
274
275 Previously the return values for undrawable pixels vs caller errors
276 changed depending on whether you used the multiple pixel calling
277 mechanism, or the single pixel mechanism.
278
279 Now:
280
281 - for an invalid parameter, such as an unknown colour, or missing
282 parameter, an empty list (or undef in scalar context) is
283 returned, and errstr() is set,
284
285 - otherwise the number of pixels drawn is returned. If none of
286 the pixels could be drawn (they were all outside the image), "0
287 but true" is returned.
288
289 https://rt.cpan.org/Ticket/Display.html?id=87650
290
291Other changes:
292
6ba09ab9
TC
293 - when drawing on an image with an alpha channel where the source
294 minimum is greater than zero, Imager would read from beyond the end
295 of a malloc() allocated buffer. In rare circumstances this could
296 lead to some of the source image not being written to the target
297 image, or possibly to a segmentation fault.
298 I don't believe this has any security concerns beyond that.
299
0d052fd9
TC
300 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
301 text drawn would be nonsense. This would also read beyond the end
302 of a malloced buffer.
303
13671b17
TC
304 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
305 truncated early.
306 https://rt.cpan.org/Ticket/Display.html?id=88993
307
d6f4e964
TC
308 - Imager::Font::Wrap no longer requires the image parameter.

310
f84f86a2
TC
311 - a documentation typo fix in Imager::Transformations
312 Thanks to Adrian Yee.
313 https://rt.cpan.org/Ticket/Display.html?id=88598
314
0179ecd6
TC
315 - Image::Probe, Imager's internal module for probing library
316 locations now searches the directories specified by LD_RUN_PATH,
317 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
318 and the corresponing s/\blib$/include/ directories for header
319 files.

330 - PNG: treat a version mismatch between headers and library as a
331 probe failure.
332 https://rt.cpan.org/Ticket/Display.html?id=86659
333
8e90f677
TC
334 - PNG: the check for benign error support is more complex than a
335 simple library version check, check for the appropriate macro.
336 Thanks for Slaven Rezic for following up on my CPAN Testers result
337 queries.

05c9b356
TC
346 - TIFF: handle SampleFormat = 2 by translating the signed integer
347 values to unsigned by flipping their sign bits.
348
349 Handle SampleFormat = 3 where possible.
350
351 SampleFormat is ignored for paletted images.
352
237d9e03
TC
353 Mixed SampleFormat are handled incorrectly, since libtiff returns
354 only the first SampleFormat value, and an image with both an alpha
355 channel and SampleFormat = 2 for color channels probably has a
356 different SampleFormat for the alpha channel.

face45e7 362
237d9e03 363 - Imager::Color's rgba() method now returns its values as integers
face45e7
TC
364 instead of floating point. (IV instead of NV).
365
19e9591b
TC
366 - The XS for i_map() and i_matrix_transform() now use the AV *
367 typemap instead of rolling their own.
368

TC
369 - The XS for DSO_call() now uses the HV * typemap instead of
370 rolling it's own.

0aaa8b4d
TC
372 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
373 i_gradgen() now use a new T_AVARRAY typemap that greatly
374 simplifies the XS code.
face45e7 375
ccd01d49
TC
376 - many other minor XS changes
377
face45e7 378 - some XS code formatting

TC
400 - rearrange Imager's test files.
401 https://rt.cpan.org/Ticket/Display.html?id=84596
402
403 - Imager::Probe::_gcc_lib_paths now forces C locale.
404 A sufficiently recent gcc prints localized keys for the search
405 paths, which avoids that localization.
406 https://rt.cpan.org/Ticket/Display.html?id=84963
407
408 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
409 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
410 and true.

427Imager 0.95 - 19 Apr 2013
428===========
429
0a2956ab
TC
430 - handle the SVf_UTF8 flag correctly on magic strings passed to
431 Imager::IO's write() and raw_write() methods.
432 This may misbehave in perl 5.6.x since the UTF8 flag may not be
433 visible in the main SV after SvGETMAGIC().
434 https://rt.cpan.org/Ticket/Display.html?id=83438

TC
443 - enable debug logging for the standard font tests
444
445 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
446 due to a bug in that version of perl.
447
448 - don't test for read() failing on a write-only handle in 5.8.x and
449 earlier, this was fixed in change 862083f7e4 in perl.

566
567 - support for giflib 5.0. (5.0.1 and later)
568 https://rt.cpan.org/Ticket/Display.html?id=79029
569 The giflib API Imager uses doesn't have a mechanism to set the
570 header version in 5.0.0.
571
572 - update the GIF library probe code to check for the new giflib 5.0.1
573 EGifSetGifVersion() function, and to check for the giflib 4.2.0
574 uninitialized gif89 bug.

578 - avoid static variables when capturing IPTC data from JPEG files
579
580 - match Imager::Font;:T1's error message translations to those from
581 later versions of T1Lib.
582
583 - for libtiff versions that support extended warning handlers (3.8.0
584 or later), use them to avoid some global variables.

TC
605 - The size of rotated images is no longer rounded up so aggressively.
606 Added rounding to the linear interpolation done for rotate() and
607 matrix_transform() for 1 and 3 channel 8-bit images.
608 Adjusted the two tranlate matrices used to build the final rotation
609 matrix to use the distance between the outlier pixels rather than
610 the pixel dimensions (ie. dimension-1).
611 With all of this the output of rotate(degrees => 270) on an 8-bit
612 image exactly matches the output of rotate(right => 270).
613 https://rt.cpan.org/Ticket/Display.html?id=77063
614
ef84bb32
TC
615Other changes:
616
617 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
618 internals, those names only matter for the XS interface.
619
620 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
621 the API level compiled into a loadable module such as
622 Imager::File::GIF doesn't match that of Imager. Previously it
623 could be difficult to determine exactly which module was failing to
624 load.
625 https://rt.cpan.org/Ticket/Display.html?id=77173
626
627 - added Imager->check_file_limits() as an interface to the
628 i_int_check_image_file_limits() API.
629
630 - Imager->set_file_limits(reset => 1) now resets the limits to the
631 defaults rather than setting them all to unlimited.

637===========
638
639Bug fixes:
640
641 - Imager::Test::is_imaged() attempted to process an "epsilon"
642 parameter but the prototype didn't allow for the extra parameter.
643 Corrected the prototype.
644
29b38678
TC
645 - when downconverting samples (eg. from floating point to 8 bit)
646 Imager now rounds the sample value rather than attempting to
647 allocate input values over output values equally. The old
648 behaviour had the probably surprising effect of converting a
649 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
650 2.
651 This may result in slightly different 8 or 16-bit output images.
652
e2a86bac
TC
653 - BI_BITFIELD BMP images were handled incorrectly, both in
654 incorrectly calculating the space required for the masks and in
655 processing the image data itself.
656 https://rt.cpan.org/Ticket/Display.html?id=76736
657
658 - some odd width BMP BI_RLE4 images use run lengths that run one off
659 the edge of the image. Imager now allows this, discarding the
660 extra column.
661
662 - odd length RLE4 runs in BMP images were decoded incorrectly.
663
82eb0687
TC
664 - pkg-config could sometimes return a library that was in a directory
665 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
666 If no -L is included in the pkg-config library information check if
667 EU::MM can find the library, and if not, search our configured
668 directories and insert that into the library flags.
669 https://rt.cpan.org/Ticket/Display.html?id=75869
670
de50f459
TC
671 - Imager::Probe can now probe for libraries with dependent libraries,
672 common for static linking, eg. libpng requires libz.
673 https://rt.cpan.org/Ticket/Display.html?id=74043
674
675 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
676
677 - added alternative probe configurations that try to link libz, to
678 handle a statically linked libpng.
679 https://rt.cpan.org/Ticket/Display.html?id=74043
680
681 - if a probe includes testcode, Imager::Probe now checks that code as
682 part of the process of checking each configuration rather than as a
683 post test of the found configuration. This allows alternate
684 configurations to be checked if a matching but non-working
685 configuration is found.

761 - setsamples() is now a true complement to getsamples() - it can
762 write 8-bit or floating point samples from a scalar or array
763 reference. This adds i_psamp() and i_psampf() to the C level API.
764
765 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
766 changed to make better use of the typemap, but these aren't part of
767 the perl level API anyway. There were no changes to the C level

TC
920
921 - add simple tests for the Imager::Test test_image generators
922

TC
923 - io_glue I/O buffering re-work:
924
925 - reorganize io_glue to do it's own buffering by default
926
927 - the unbuffered functions are available as i_io_raw_read() (or
928 raw_read() from perl) etc but are not recommended for typical
929 use.
930
931 - use the new i_io_peekn() when checking for file magic to avoid
932 seek, allowing Imager to detect the file type and read the file
933 from an unseekable stream (for formats that don't use random
934 access)
935
936 - added several new I/O layer API functions.
937
938 - fix the TGA performance problem, most noticably on Win32
939 https://rt.cpan.org/Ticket/Display.html?id=70037
940
941 - TIFF now uses wrapper functions of the correct types to avoid casts
942 https://rt.cpan.org/Ticket/Display.html?id=69912
943
944 - the callback IO object did its own buffering, controlled by the
945 maxbuffer parameter supplied to the read() and write() methods.
946 This buffering has been removed, to avoid redundancy with the
947 common io_glue buffering. This also avoids a bug in that code
948 which could rarely pass a zero length to the read callback and
949 then panic about the result.
950
951 - the callback IO object now tests the result of calling the close
952 callback, which should return true for success.
953
954 - the PNM reader did its own buffering. This buffering has been
955 removed to avoid redundancy with the common io_glue buffering.
956
957 - previously the read handlers for fd and callback I/O layers would
958 call the underlying interface (POSIX read or your supplied callback)
959 until it filled the buffer. It now only makes one call.
960
961 - added public constructors for I/O layer objects (see Imager::IO)
962
963 - all core file handlers now use the i_io_foo() wrappers to gain
964 access to buffered I/O rather than calling the I/O layer
965 callbacks directly.
966
967 - all core file handlers now check for error on close.
968
969 - Backward compatibility: if you hava custom file handlers, you can
970 use i_io_write() etc since they're available as macros in older
971 versions of Imager.
972
973 - eliminate the final remnants of io_glue_commit_types().
974
975 - bump IMAGER_API_VERSION, since the above may break assumptions.
976
977 - removed the long unused i_gen_reader() and i_gen_writer() utility
978 functions.

989 lead to an infinite loop.

1040
1041Development release as a sanity check for the types re-work.
8d14daab
TC
1042
1043Massive types re-work:
1044
1045 - the type used internally for pixel co-ordinates and image sizes is
1046 now 64-bit on 64-bit platforms (at least sane ones).
1047
1048 - size_t is now used consistently for memory block sizes.
1049
1050 - since this changes the binary interface, the Imager API version has
1051 been incremented. Any module that uses the API will need to be
1052 rebuilt. In most cases that will be enough, but calls to any APIs
1053 that take a pointer to image sizes may need source changes.
1054
1055 - you should be able to create very large images on 64-bit systems,
1056 if you have enough memory. Successfully created a 32768 x 49192 x
1057 3 channel image, filled with a tiled image and scaled it. The
1058 unscaled image was also successfully saved to a JPEG.
1059
1060 - check the image size before attempting to write BMP, GIF, JPEG,
1061 PNG, SGI, TGA, TIFF images.
1062
1063 - correctly handle reading TGA images over 32767 pixels wide or tall.
1064
1065Incidental changes:
1066
1067 - the gif_left and gif_top tags are now clamped to non-negative
1068 values when writing a GIF image.
1069
1070 - removed dead callback read/write code
1071
1072The default maximum memory size when reading files is now 1G.

1775 - some TGA images weren't being detected correctly as TGA images
1776 https://rt.cpan.org/Ticket/Display.html?id=32925
1777
1778 - handling of the left-over bit for 16-bit/pixel TGA images has been
1779 changed to match the behaviour of the GIMP. Previously the bit
1780 being set was treated as an opaque pixel, but one user reported a
1781 problem with loading such an image. I haven't been able to find any
1782 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1783 I'll match it's behaviour. See issue 114913 in the GIMP's
1784 bugzilla.

1794 - the old dynaload code used Mach API functions to load dynamic
1795 libraries on Mac OS X. These APIs have been deprecated in OS X
1796 10.5 and were causing some build problems.

1798 will need version 10.3 or later of OS X.

2106
2107Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2108
2109There is one new feature:
2110
2111 - the Win32 font driver now supports UTF8 (RT 22166)
2112 http://www.cpanforum.com/threads/3276
2113 http://rt.cpan.org/Ticket/Display.html?id=22166
2114
2115Several bugs were fixed:
2116
2117 - the string() method would not output the string "0"
2118 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2119
2120 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2121 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2122
2123 - the gif_disposal and gif_user_input tags weren't being read from
2124 the file correctly
2125 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2126
2127 - gif.c was failing to build under MSVC
2128 http://rt.cpan.org/Ticket/Display.html?id=23922
2129
2130 - in some cases strings passed to the string() method were treated as
2131 terminated by NUL (chr 0)
2132 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2133
2134 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2135 that's the default build name for zlib on Win32.
2136 http://rt.cpan.org/Ticket/Display.html?id=23064
2137
2138 - search $Config{incpath} for headers too, which we should have been
2139 doing all along.
2140
2141Win32 font driver fixes:
2142
2143 - the global descent value from bounding box was the wrong sign
2144 http://www.cpanforum.com/threads/3276
2145
2146 - if the first or last glyph overflowed the left or right side of the
2147 advance width they would be clipped
2148
2149
2150Imager 0.54 - 14 Sep 2006
2151===========
2152
2153This is primarily a feature release:
2154
2155 - a new qtype value 'mixing' has been added to the scale()
2156 method. This is faster than 'normal', slower than 'preview'. This
2157 is based on the method used by pnmscale, and seems to produce less
2158 blurry results than normal.
2159 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2160
2161 - the rubthrough() method can now render onto images with an alpha
2162 channel.
2163 http://rt.cpan.org/Ticket/Display.html?id=20678
2164
2165 - the read_multi() method now falls back to calling doing a single
2166 image read via the read() method and write_multi() will now fall
2167 back to calling write() if a single image is supplied. This means
2168 you can simply call the read_multi() or write_multi() functions
2169 without having to check if the type is formatted by that method.
2170 http://rt.cpan.org/Ticket/Display.html?id=19457
2171 http://rt.cpan.org/Ticket/Display.html?id=19458
2172
2173 - the GIF loop extension can now be written. If you don't have
2174 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2175 should upgrade.
2176 http://rt.cpan.org/Ticket/Display.html?id=21185
2177
2178 - getscanline() and setscanline() can now read/write palette index
2179 based data from/to the image for paletted images, by setting type to
2180 'index'.
2181 http://rt.cpan.org/Ticket/Display.html?id=20338
2182
2183 - we no longer hassle you to disable GIF support
2184 http://rt.cpan.org/Ticket/Display.html?id=20687
2185
2186 - minor documentation fixes

2200Imager 0.52 - 25 Jul 2006
2201===========
2202
2203This is primarily a feature release, but contains a fair few bug
2204fixes, new features:
2205
2206 - ability to read and write MS Windows ICO and CUR files
2207
2208 - you can now add file format plugins to support new file formats
2209
2210 - add POD coverage tests
2211
2212 - setcolors() and addcolors() now accept color names and so on
2213 instead of requiring Imager::Color objects.
2214 http://rt.cpan.org/Ticket/Display.html?id=20056
2215
2216 - flood_fill() can now fill to a specified border color instead of
2217 just to the area the same color as the seed.
2218 http://rt.cpan.org/Ticket/Display.html?id=19618
2219
2220
2221Bug fixes:
2222
2223 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2224 calculating the advance width.
2225 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2226
2227 - bounding_box for the T1 driver wasn't including leading and
2228 trailing spaces in the bounding box as the other drivers did, it also
2229 produced strange results for empty strings or strings containing only
2230 spaces
2231
2232 - when reading CMYK jpeg images they were being transferred to the
2233 image object as is, producing a four channel image. It only looked ok
2234 due to an old still unfixed Photoshop bug. We now convert from the
2235 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2236 http://rt.cpan.org/Ticket/Display.html?id=20416
2237
2238 - reading a CYMK TIFF would result in a 4 channel image, reading any
2239 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2240 result in an error.
2241 http://rt.cpan.org/Ticket/Display.html?id=20415
2242
2243 - added /usr/local/include to the default include search path, since
2244 we were already searching /usr/local/lib for libraries.
2245
2246And various minor fixes and documentation updates.
