12 - fix the skip check for the iolayer qr// buffer test
13
14 - improve error reporting for the iolayer test failing on a small
15 number of Win32 CPAN testers

20 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
21 the blue channel in the generated palette, and allow each color
22 component to be in the range 100..255 instead of just 100..254.
23 Thanks to Ralf Neubauer.
24 https://rt.cpan.org/Ticket/Display.html?id=97086
25
26 - revert "improved the XS for i_io_read() and i_io_raw_read()"
27 This caused problems with older perls and didn't provide much of a
28 performance improvement.
29
5bf25bc2 30 - support Inline 0.57 and later.
6d47a6af 31 Inline 0.57 changed the "with" interface.

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

41 - GIF: add support for giflib 5.1.0, which added error code pointer
42 parameters to EGifCloseFile() and DGifCloseFile().
43 https://rt.cpan.org/Ticket/Display.html?id=96756
44
45 - GIF: avoid a double-free when do_write() fails.

54Imager 0.99 - 25 Jun 2014
55===========
56
dce1523b
TC
57 - Imager::IO->new_buffer() (and hence Imager->read()'s data
58 parameter) now accepts a reference to a scalar as well as just a
59 plain scalar.
6a160bce 60 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
61
62 - Imager::IO->new_buffer() now always makes a copy of the passed in
63 buffer to avoid problems with temporary objects used for the return
64 value of SvPVbyte().
6a160bce 65 https://rt.cpan.org/Ticket/Display.html?id=92785

TC
67 - improved the XS for i_io_read() and i_io_raw_read()
68 https://rt.cpan.org/Ticket/Display.html?id=92738
69
70 - load plugins from absolute paths on Android
71 Thanks to Brian Fraser.
72 https://rt.cpan.org/Ticket/Display.html?id=93272
73
6a160bce
TC
74 - added the jpeg_optimize parameter for writing JPEG files. This can
75 significantly reduce file sizes, but uses more memory and time.
76 https://rt.cpan.org/Ticket/Display.html?id=94292
77
14fd9e5d
TC
78 - the autolevels filter now works on the luminosity of the image
79 rather then working per channel. The old autolevels filter is
80 still available as "autolevels_skew".
81 https://rt.cpan.org/Ticket/Display.html?id=94413
82
75d54149
TC
83 - Imager::File::PNG now supports libpng 1.6.10.
84 1.6.10 changed CRC errors from benign errors to normal errors,
85 which broke the test which used CRC errors to check for benign
86 error support. Switched to using a 1-bit grey-scale image with a
87 palette to test for benign errors.

90Imager 0.98 - 3 Jan 2014
91===========
92
f84f86a2
TC
93Incompatible changes:
94
95 - the return value of setpixel() has changed.
96
97 Previously the return values for undrawable pixels vs caller errors
98 changed depending on whether you used the multiple pixel calling
99 mechanism, or the single pixel mechanism.
100
101 Now:
102
103 - for an invalid parameter, such as an unknown colour, or missing
104 parameter, an empty list (or undef in scalar context) is
105 returned, and errstr() is set,
106
107 - otherwise the number of pixels drawn is returned. If none of
108 the pixels could be drawn (they were all outside the image), "0
109 but true" is returned.
110
111 https://rt.cpan.org/Ticket/Display.html?id=87650
112
113Other changes:
114
6ba09ab9
TC
115 - when drawing on an image with an alpha channel where the source
116 minimum is greater than zero, Imager would read from beyond the end
117 of a malloc() allocated buffer. In rare circumstances this could
118 lead to some of the source image not being written to the target
119 image, or possibly to a segmentation fault.
120 I don't believe this has any security concerns beyond that.
121
0d052fd9
TC
122 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
123 text drawn would be nonsense. This would also read beyond the end
124 of a malloced buffer.
125
13671b17
TC
126 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
127 truncated early.
128 https://rt.cpan.org/Ticket/Display.html?id=88993
129
d6f4e964
TC
130 - Imager::Font::Wrap no longer requires the image parameter.
131 https://rt.cpan.org/Ticket/Display.html?id=87338
132
f84f86a2
TC
133 - a documentation typo fix in Imager::Transformations
134 Thanks to Adrian Yee.
135 https://rt.cpan.org/Ticket/Display.html?id=88598
136
0179ecd6
TC
137 - Image::Probe, Imager's internal module for probing library
138 locations now searches the directories specified by LD_RUN_PATH,
139 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
140 and the corresponing s/\blib$/include/ directories for header
141 files.

149Imager 0.96_02 - 8 Jul 2013
150==============
151
aaf82685
TC
152 - PNG: treat a version mismatch between headers and library as a
153 probe failure.
154 https://rt.cpan.org/Ticket/Display.html?id=86659
155
8e90f677
TC
156 - PNG: the check for benign error support is more complex than a
157 simple library version check, check for the appropriate macro.
158 Thanks for Slaven Rezic for following up on my CPAN Testers result
159 queries.
160 https://rt.cpan.org/Ticket/Display.html?id=86659

162 - W32: add a missing head1 AUTHORS to the old Win32.pm

166==============
167
05c9b356
TC
168 - TIFF: handle SampleFormat = 2 by translating the signed integer
169 values to unsigned by flipping their sign bits.
170
171 Handle SampleFormat = 3 where possible.
172
173 SampleFormat is ignored for paletted images.
174
237d9e03
TC
175 Mixed SampleFormat are handled incorrectly, since libtiff returns
176 only the first SampleFormat value, and an image with both an alpha
177 channel and SampleFormat = 2 for color channels probably has a
178 different SampleFormat for the alpha channel.

face45e7 182 - XS clean up:
29969fa2 183 https://rt.cpan.org/Ticket/Display.html?id=69243
face45e7 184
237d9e03 185 - Imager::Color's rgba() method now returns its values as integers
face45e7
TC
186 instead of floating point. (IV instead of NV).
187
19e9591b
TC
188 - The XS for i_map() and i_matrix_transform() now use the AV *
189 typemap instead of rolling their own.
190
75cebca8
TC
191 - The XS for DSO_call() now uses the HV * typemap instead of
192 rolling it's own.
193
0aaa8b4d
TC
194 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
195 i_gradgen() now use a new T_AVARRAY typemap that greatly
196 simplifies the XS code.
face45e7 197
ccd01d49
TC
198 - many other minor XS changes
199
face45e7 200 - some XS code formatting
a54e32ba 201
dcab59bc
TC
202 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
203 now renders in alpha-combining mode, to match antialiased output.
204 https://rt.cpan.org/Ticket/Display.html?id=73359
b482243a 205
8db7b6fa
TC
206 - add sample code and cookbook notes for drawing a blurred drop-shadow.
207
208 - add support for libpng 1.6, which changed the defaults for
209 reporting some types of error.
210 https://rt.cpan.org/Ticket/Display.html?id=85746
211
dc076f98
TC
212 - FT2: use gsamp/psamp() to transfer pixels from the work image to
213 the output image instead of gpix/ppix.
214 https://rt.cpan.org/Ticket/Display.html?id=83478
215

221
c2e251d9
TC
222 - rearrange Imager's test files.
223 https://rt.cpan.org/Ticket/Display.html?id=84596
224
225 - Imager::Probe::_gcc_lib_paths now forces C locale.
226 A sufficiently recent gcc prints localized keys for the search
227 paths, which avoids that localization.
228 https://rt.cpan.org/Ticket/Display.html?id=84963
229
230 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
231 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
232 and true.
233 https://rt.cpan.org/Ticket/Display.html?id=85262
234 reported by Andreas König
235

237 found.
238 https://rt.cpan.org/Ticket/Display.html?id=74875
239
240 - fix some spelling errors detected by the newer aspell in Debian
241 Wheezy.
242
243 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
244 thanks to gregor herrmann <gregoa@debian.org>
245 https://rt.cpan.org/Ticket/Display.html?id=85413

TC
249Imager 0.95 - 19 Apr 2013
250===========
251
0a2956ab
TC
252 - handle the SVf_UTF8 flag correctly on magic strings passed to
253 Imager::IO's write() and raw_write() methods.
254 This may misbehave in perl 5.6.x since the UTF8 flag may not be
255 visible in the main SV after SvGETMAGIC().
256 https://rt.cpan.org/Ticket/Display.html?id=83438
257
258 - document that bounding_box() ignores the transformation matrix
259 supplied to tranform() for fonts.

262Imager 0.94_02 - 5 Apr 2013
263==============
264
1540d1d4
TC
265 - enable debug logging for the standard font tests
266
267 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
268 due to a bug in that version of perl.
269
270 - don't test for read() failing on a write-only handle in 5.8.x and
271 earlier, this was fixed in change 862083f7e4 in perl.
272
273 - report the version of Inline found during testing (an attempt to
274 diagnose some intermittent failures.)

276Imager 0.94_01 - 2 Mar 2013
277==============
278
14a4ea18 279 - NOTE: possibly backward incompatible:
3dcf7595
TC
280 support reading from/writing to perl filehandes that aren't raw
281 files.
282
283 This allows Imager's I/O to honour handles with layers such as
284 gzip, scalar file handles or tied file handles.
285
14a4ea18 286 This is backward incompatible in that previous Imager would simply
3dcf7595
TC
287 use fileno() to retrieve the fd for the file and call write(2) etc
288 on it directly.
04d8c568
TC
289 https://rt.cpan.org/Ticket/Display.html?id=78843
290
291 - moved most of README to lib/Imager/Install.pod which should make it
292 more accessible to the "web" generation, also significantly updated
293 and re-worked it.
3dcf7595 294
ca96f811
TC
295 - updated README's for the separately distributed modules to refer to
296 Imager::Install, and that they need -dev versions of packages
297 https://rt.cpan.org/Ticket/Display.html?id=81265
298
26e8a226
TC
299 - the JPEG test code now reports the compile-time library version

41125e7d 310
c732ffa5
TC
311 - drawing text to a channel with FT2 would draw with random coverage
312 due to an uninitialized alpha channel.
313
314 - marked the function pointer underlying the mm_log() API with the
315 correct gcc magic and fixed the resulting warnings.
316
317 - fixed some other compiler warnings
318
14a4ea18
TC
319 - Imager::Font::W32 now properly reports text drawing errors
320 https://rt.cpan.org/Ticket/Display.html?id=70098

14a4ea18
TC
323 strings passed as text to draw(), bounding_box(), has_chars(),
324 glyph_names() (where supported) in each of the font drivers.
0a2956ab
TC
325 This may misbehave in perl 5.6.x since the UTF8 flag may not be
326 visible in the main SV after SvGETMAGIC().

331
332Variations on some of these changes were included in development
333releases.
334
4be61824
TC
335 - improved thread safety
336 - the internal error stack and log file handle are now in a per-thread
337 context object
338 - JPEG now captures IPTC information in a thread-safe way
339 - avoid globals where possible for warning capture in libtiff
244725cf

360===========
361
362Bug fixes:
71fbe41a
TC
363
364 - previously a transparency enabled GIF write (the default) would
365 always use a GIF89a header even if none of the images were
366 transparent.

387Enhancements:
388
389 - support for giflib 5.0. (5.0.1 and later)
390 https://rt.cpan.org/Ticket/Display.html?id=79029
391 The giflib API Imager uses doesn't have a mechanism to set the
392 header version in 5.0.0.
393
394 - update the GIF library probe code to check for the new giflib 5.0.1
395 EGifSetGifVersion() function, and to check for the giflib 4.2.0
396 uninitialized gif89 bug.
397 https://rt.cpan.org/Ticket/Display.html?id=79679
398 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
399
400 - avoid static variables when capturing IPTC data from JPEG files
401
402 - match Imager::Font;:T1's error message translations to those from
403 later versions of T1Lib.
404
405 - for libtiff versions that support extended warning handlers (3.8.0
406 or later), use them to avoid some global variables.
407
408 - note Image::ExifTool for better metadata support.

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

436
ef84bb32
TC
437Other changes:
438
439 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
440 internals, those names only matter for the XS interface.
441
442 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
443 the API level compiled into a loadable module such as
444 Imager::File::GIF doesn't match that of Imager. Previously it

459===========
460
461Bug fixes:

464 parameter but the prototype didn't allow for the extra parameter.
465 Corrected the prototype.

467 - when downconverting samples (eg. from floating point to 8 bit)
468 Imager now rounds the sample value rather than attempting to
469 allocate input values over output values equally. The old
470 behaviour had the probably surprising effect of converting a
471 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
472 2.
473 This may result in slightly different 8 or 16-bit output images.

475 - BI_BITFIELD BMP images were handled incorrectly, both in
476 incorrectly calculating the space required for the masks and in
477 processing the image data itself.

479
480 - some odd width BMP BI_RLE4 images use run lengths that run one off
481 the edge of the image. Imager now allows this, discarding the
482 extra column.

494 common for static linking, eg. libpng requires libz.
495 https://rt.cpan.org/Ticket/Display.html?id=74043
496
497 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.

500 handle a statically linked libpng.
501 https://rt.cpan.org/Ticket/Display.html?id=74043
502
503 - if a probe includes testcode, Imager::Probe now checks that code as
504 part of the process of checking each configuration rather than as a
505 post test of the found configuration. This allows alternate
506 configurations to be checked if a matching but non-working
507 configuration is found.

745 - io_glue I/O buffering re-work:
746
747 - reorganize io_glue to do it's own buffering by default
748
749 - the unbuffered functions are available as i_io_raw_read() (or
750 raw_read() from perl) etc but are not recommended for typical
751 use.
752
753 - use the new i_io_peekn() when checking for file magic to avoid
754 seek, allowing Imager to detect the file type and read the file
755 from an unseekable stream (for formats that don't use random
756 access)
757
758 - added several new I/O layer API functions.

763 - TIFF now uses wrapper functions of the correct types to avoid casts
764 https://rt.cpan.org/Ticket/Display.html?id=69912
765
766 - the callback IO object did its own buffering, controlled by the
767 maxbuffer parameter supplied to the read() and write() methods.
768 This buffering has been removed, to avoid redundancy with the
769 common io_glue buffering. This also avoids a bug in that code
770 which could rarely pass a zero length to the read callback and
771 then panic about the result.
772
773 - the callback IO object now tests the result of calling the close
774 callback, which should return true for success.
775
776 - the PNM reader did its own buffering. This buffering has been
777 removed to avoid redundancy with the common io_glue buffering.
778
779 - previously the read handlers for fd and callback I/O layers would
780 call the underlying interface (POSIX read or your supplied callback)
781 until it filled the buffer. It now only makes one call.
782
783 - added public constructors for I/O layer objects (see Imager::IO)
784
785 - all core file handlers now use the i_io_foo() wrappers to gain
786 access to buffered I/O rather than calling the I/O layer
787 callbacks directly.
788
789 - all core file handlers now check for error on close.
790
791 - Backward compatibility: if you hava custom file handlers, you can
792 use i_io_write() etc since they're available as macros in older
793 versions of Imager.
794
795 - eliminate the final remnants of io_glue_commit_types().
796
797 - bump IMAGER_API_VERSION, since the above may break assumptions.
798
799 - removed the long unused i_gen_reader() and i_gen_writer() utility
800 functions.

863Development release as a sanity check for the types re-work.

TC
864
865Massive types re-work:
866
867 - the type used internally for pixel co-ordinates and image sizes is
868 now 64-bit on 64-bit platforms (at least sane ones).
869
870 - size_t is now used consistently for memory block sizes.
871
872 - since this changes the binary interface, the Imager API version has
873 been incremented. Any module that uses the API will need to be
874 rebuilt. In most cases that will be enough, but calls to any APIs
875 that take a pointer to image sizes may need source changes.
876
877 - you should be able to create very large images on 64-bit systems,
878 if you have enough memory. Successfully created a 32768 x 49192 x
879 3 channel image, filled with a tiled image and scaled it. The
880 unscaled image was also successfully saved to a JPEG.
881
882 - check the image size before attempting to write BMP, GIF, JPEG,
883 PNG, SGI, TGA, TIFF images.
884
885 - correctly handle reading TGA images over 32767 pixels wide or tall.
886
887Incidental changes:
888
889 - the gif_left and gif_top tags are now clamped to non-negative
890 values when writing a GIF image.
891

1341 - the conv filter now enforces that the sum of the coefficients is
1342 non-zero. Also, rather than skipping pixels off the edge off the
1343 edge of the image, the closest edge pixel is used. Previously
1344 dividing by the zero sum of coefficients could cause invalid
1345 results or runtime exceptions.

1541 - moved the imtoc.perl code into Imager::Preprocess

1543 - paste() and rubthrough() now adapt the source image data to the
1544 destination, so you can now safely paste/rubthrough from greyscale
1545 images to color images or back, or from alpha channel images to
1546 noalpha channels or back.
1547 https://rt.cpan.org/Ticket/Display.html?id=30908
1548
1549 - rubthrough() now falls back to pasting when the source doesn't have
1550 an alpha channel. This effectively treats the source as having a
1551 max alpha channel, the right thing to do.
1552 http://rt.cpan.org/Ticket/Display.html?id=29944
1553
1554 - re-worked most of the area filling code to use a common set of
1555 functions when filling.
1556 Corrected normal combine mode.
1557 Rewrote most of the combine modes to match the way the SVG draft
1558 defines them with respect to a translucent source and destination.

1561 similarly.

1601 changed to match the behaviour of the GIMP. Previously the bit
1602 being set was treated as an opaque pixel, but one user reported a
1603 problem with loading such an image. I haven't been able to find any
1604 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1605 I'll match it's behaviour. See issue 114913 in the GIMP's
1606 bugzilla.

1763 - the mask for ICO/CUR images is now applied as an alpha channel to
1764 the returned image. For the old behaviour, supply ico_masked => 0
1765 to read() or read_multi(). This should be less confusing when
1766 using Imager as a general image processor.

1769Bug fixes:
1770
1771 - in some cases it's possible for giflib/libungif to return color
1772 indexes outside the range of colors defined by the image's palette.
1773 We now expand the palette to match the indexes used.
1774 Thanks to Gabriel Vasseur for reporting this.

1779 - to avoid confusion, channels not present in the image are returned as
1780 zero by getscanline(). This has no effect on the C level i_glin()
1781 and i_glinf() API functions which continue to not set the unused
1782 channels.

1924Imager 0.55 - 16 Dec 2006
1925===========
1926
1927This is primarily a bug fix release.
1928
1929Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1930
1931There is one new feature:
1932
1933 - the Win32 font driver now supports UTF8 (RT 22166)
1934 http://www.cpanforum.com/threads/3276
1935 http://rt.cpan.org/Ticket/Display.html?id=22166
1936
1937Several bugs were fixed:
1938
1939 - the string() method would not output the string "0"
1940 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1941
1942 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1943 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1944
1945 - the gif_disposal and gif_user_input tags weren't being read from
1946 the file correctly
1947 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1948
1949 - gif.c was failing to build under MSVC
1950 http://rt.cpan.org/Ticket/Display.html?id=23922
1951
1952 - in some cases strings passed to the string() method were treated as
1953 terminated by NUL (chr 0)
1954 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1955
1956 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1957 that's the default build name for zlib on Win32.
1958 http://rt.cpan.org/Ticket/Display.html?id=23064
1959
1960 - search $Config{incpath} for headers too, which we should have been
1961 doing all along.
1962
1963Win32 font driver fixes:
1964
1965 - the global descent value from bounding box was the wrong sign
1966 http://www.cpanforum.com/threads/3276
1967
1968 - if the first or last glyph overflowed the left or right side of the
1969 advance width they would be clipped
1970
1971
1972Imager 0.54 - 14 Sep 2006
1973===========
1974
1975This is primarily a feature release:
1976
1977 - a new qtype value 'mixing' has been added to the scale()
1978 method. This is faster than 'normal', slower than 'preview'. This
1979 is based on the method used by pnmscale, and seems to produce less
1980 blurry results than normal.
1981 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1982
1983 - the rubthrough() method can now render onto images with an alpha
1984 channel.
1985 http://rt.cpan.org/Ticket/Display.html?id=20678
1986
1987 - the read_multi() method now falls back to calling doing a single
1988 image read via the read() method and write_multi() will now fall
1989 back to calling write() if a single image is supplied. This means
1990 you can simply call the read_multi() or write_multi() functions
1991 without having to check if the type is formatted by that method.
1992 http://rt.cpan.org/Ticket/Display.html?id=19457
1993 http://rt.cpan.org/Ticket/Display.html?id=19458
1994
1995 - the GIF loop extension can now be written. If you don't have
1996 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1997 should upgrade.
1998 http://rt.cpan.org/Ticket/Display.html?id=21185
1999
2000 - getscanline() and setscanline() can now read/write palette index
2001 based data from/to the image for paletted images, by setting type to
2002 'index'.
2003 http://rt.cpan.org/Ticket/Display.html?id=20338
2004
2005 - we no longer hassle you to disable GIF support
2006 http://rt.cpan.org/Ticket/Display.html?id=20687
2007
2008 - minor documentation fixes
2009
2010
2011Imager 0.53 - 26 Jul 2006
2012===========
2013
2014This is a bugfix release.
2015
2016Some test code was left in a code path not covered by the test
2017suite. A test was added to cover this code path and the test code was
2018removed.

2021
2022Imager 0.52 - 25 Jul 2006
2023===========
2024
2025This is primarily a feature release, but contains a fair few bug
2026fixes, new features:
2027
2028 - ability to read and write MS Windows ICO and CUR files
2029
2030 - you can now add file format plugins to support new file formats
2031
2032 - add POD coverage tests
2033
2034 - setcolors() and addcolors() now accept color names and so on
2035 instead of requiring Imager::Color objects.
2036 http://rt.cpan.org/Ticket/Display.html?id=20056
2037
2038 - flood_fill() can now fill to a specified border color instead of
2039 just to the area the same color as the seed.
2040 http://rt.cpan.org/Ticket/Display.html?id=19618
2041
2042
2043Bug fixes:
2044
2045 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2046 calculating the advance width.
2047 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2048
2049 - bounding_box for the T1 driver wasn't including leading and
2050 trailing spaces in the bounding box as the other drivers did, it also
2051 produced strange results for empty strings or strings containing only
2052 spaces
2053
2054 - when reading CMYK jpeg images they were being transferred to the
2055 image object as is, producing a four channel image. It only looked ok
2056 due to an old still unfixed Photoshop bug. We now convert from the
2057 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2058 http://rt.cpan.org/Ticket/Display.html?id=20416
2059
2060 - reading a CYMK TIFF would result in a 4 channel image, reading any
2061 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2062 result in an error.
2063 http://rt.cpan.org/Ticket/Display.html?id=20415
2064
2065 - added /usr/local/include to the default include search path, since
2066 we were already searching /usr/local/lib for libraries.
2067
2068And various minor fixes and documentation updates.
2069
2070
2071Imager 0.51 - 23 Apr 2006
