16 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
17 the blue channel in the generated palette, and allow each color
18 component to be in the range 100..255 instead of just 100..254.
19 Thanks to Ralf Neubauer.

21
22 - revert "improved the XS for i_io_read() and i_io_raw_read()"
23 This caused problems with older perls and didn't provide much of a
24 performance improvement.
25
5bf25bc2 26 - support Inline 0.57 and later.
6d47a6af 27 Inline 0.57 changed the "with" interface.

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

37 - GIF: add support for giflib 5.1.0, which added error code pointer
38 parameters to EGifCloseFile() and DGifCloseFile().
39 https://rt.cpan.org/Ticket/Display.html?id=96756
40
41 - GIF: avoid a double-free when do_write() fails.
42
28104a85 43 - fix SV type probing to work on perl before 5.12. Broken in 0.99.

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

50Imager 0.99 - 25 Jun 2014
51===========
52
dce1523b
TC
53 - Imager::IO->new_buffer() (and hence Imager->read()'s data
54 parameter) now accepts a reference to a scalar as well as just a
55 plain scalar.
6a160bce 56 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
57
58 - Imager::IO->new_buffer() now always makes a copy of the passed in
59 buffer to avoid problems with temporary objects used for the return
60 value of SvPVbyte().
6a160bce 61 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 62
c757e211
TC
63 - improved the XS for i_io_read() and i_io_raw_read()
64 https://rt.cpan.org/Ticket/Display.html?id=92738
65
66 - load plugins from absolute paths on Android
67 Thanks to Brian Fraser.
68 https://rt.cpan.org/Ticket/Display.html?id=93272
69
6a160bce
TC
70 - added the jpeg_optimize parameter for writing JPEG files. This can
71 significantly reduce file sizes, but uses more memory and time.
72 https://rt.cpan.org/Ticket/Display.html?id=94292
73
14fd9e5d
TC
74 - the autolevels filter now works on the luminosity of the image
75 rather then working per channel. The old autolevels filter is
76 still available as "autolevels_skew".
77 https://rt.cpan.org/Ticket/Display.html?id=94413
78
75d54149
TC
79 - Imager::File::PNG now supports libpng 1.6.10.
80 1.6.10 changed CRC errors from benign errors to normal errors,
81 which broke the test which used CRC errors to check for benign
82 error support. Switched to using a 1-bit grey-scale image with a
83 palette to test for benign errors.

86Imager 0.98 - 3 Jan 2014
87===========
88
f84f86a2
TC
89Incompatible changes:
90
91 - the return value of setpixel() has changed.
92
93 Previously the return values for undrawable pixels vs caller errors
94 changed depending on whether you used the multiple pixel calling
95 mechanism, or the single pixel mechanism.
96
97 Now:
98
99 - for an invalid parameter, such as an unknown colour, or missing
100 parameter, an empty list (or undef in scalar context) is
101 returned, and errstr() is set,
102
103 - otherwise the number of pixels drawn is returned. If none of
104 the pixels could be drawn (they were all outside the image), "0
105 but true" is returned.
106
107 https://rt.cpan.org/Ticket/Display.html?id=87650
108
109Other changes:
110
6ba09ab9
TC
111 - when drawing on an image with an alpha channel where the source
112 minimum is greater than zero, Imager would read from beyond the end
113 of a malloc() allocated buffer. In rare circumstances this could
114 lead to some of the source image not being written to the target
115 image, or possibly to a segmentation fault.
116 I don't believe this has any security concerns beyond that.
117
0d052fd9
TC
118 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
119 text drawn would be nonsense. This would also read beyond the end
120 of a malloced buffer.
121
13671b17
TC
122 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
123 truncated early.
124 https://rt.cpan.org/Ticket/Display.html?id=88993
125
d6f4e964
TC
126 - Imager::Font::Wrap no longer requires the image parameter.
127 https://rt.cpan.org/Ticket/Display.html?id=87338
128
f84f86a2
TC
129 - a documentation typo fix in Imager::Transformations
130 Thanks to Adrian Yee.
131 https://rt.cpan.org/Ticket/Display.html?id=88598
132
0179ecd6
TC
133 - Image::Probe, Imager's internal module for probing library
134 locations now searches the directories specified by LD_RUN_PATH,
135 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
136 and the corresponing s/\blib$/include/ directories for header
137 files.

TC
145Imager 0.96_02 - 8 Jul 2013
146==============
147
aaf82685
TC
148 - PNG: treat a version mismatch between headers and library as a
149 probe failure.
150 https://rt.cpan.org/Ticket/Display.html?id=86659
151
8e90f677
TC
152 - PNG: the check for benign error support is more complex than a
153 simple library version check, check for the appropriate macro.
154 Thanks for Slaven Rezic for following up on my CPAN Testers result
155 queries.
156 https://rt.cpan.org/Ticket/Display.html?id=86659
157

158 - W32: add a missing head1 AUTHORS to the old Win32.pm
159 https://rt.cpan.org/Ticket/Display.html?id=86658
160

TC
162==============
163
05c9b356
TC
164 - TIFF: handle SampleFormat = 2 by translating the signed integer
165 values to unsigned by flipping their sign bits.
166
167 Handle SampleFormat = 3 where possible.
168
169 SampleFormat is ignored for paletted images.
170
237d9e03
TC
171 Mixed SampleFormat are handled incorrectly, since libtiff returns
172 only the first SampleFormat value, and an image with both an alpha
173 channel and SampleFormat = 2 for color channels probably has a
174 different SampleFormat for the alpha channel.

face45e7 178 - XS clean up:
29969fa2 179 https://rt.cpan.org/Ticket/Display.html?id=69243
face45e7 180
237d9e03 181 - Imager::Color's rgba() method now returns its values as integers
face45e7
TC
182 instead of floating point. (IV instead of NV).
183
19e9591b
TC
184 - The XS for i_map() and i_matrix_transform() now use the AV *
185 typemap instead of rolling their own.
186
75cebca8
TC
187 - The XS for DSO_call() now uses the HV * typemap instead of
188 rolling it's own.
189
0aaa8b4d
TC
190 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
191 i_gradgen() now use a new T_AVARRAY typemap that greatly
192 simplifies the XS code.
face45e7 193
ccd01d49
TC
194 - many other minor XS changes
195
face45e7 196 - some XS code formatting
a54e32ba 197
dcab59bc
TC
198 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
199 now renders in alpha-combining mode, to match antialiased output.
200 https://rt.cpan.org/Ticket/Display.html?id=73359
b482243a 201
8db7b6fa
TC
202 - add sample code and cookbook notes for drawing a blurred drop-shadow.
203
204 - add support for libpng 1.6, which changed the defaults for
205 reporting some types of error.
206 https://rt.cpan.org/Ticket/Display.html?id=85746
207
dc076f98
TC
208 - FT2: use gsamp/psamp() to transfer pixels from the work image to
209 the output image instead of gpix/ppix.
210 https://rt.cpan.org/Ticket/Display.html?id=83478
211
98747309
TC
212 - eliminate various GCC warnings, mostly initialized but otherwise
213 unused variables.

215Imager 0.96 - 19 May 2013
216===========
217
c2e251d9
TC
218 - rearrange Imager's test files.
219 https://rt.cpan.org/Ticket/Display.html?id=84596
220
221 - Imager::Probe::_gcc_lib_paths now forces C locale.
222 A sufficiently recent gcc prints localized keys for the search
223 paths, which avoids that localization.
224 https://rt.cpan.org/Ticket/Display.html?id=84963
225
226 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
227 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
228 and true.
229 https://rt.cpan.org/Ticket/Display.html?id=85262
230 reported by Andreas König
231
232 - add a test for unclosed POD in C source, and fix the errors it
233 found.
234 https://rt.cpan.org/Ticket/Display.html?id=74875
235
236 - fix some spelling errors detected by the newer aspell in Debian
237 Wheezy.
238
239 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
240 thanks to gregor herrmann <gregoa@debian.org>
241 https://rt.cpan.org/Ticket/Display.html?id=85413
242
243 - add a test for standard =head1 commands and fix the errors found

TC
245Imager 0.95 - 19 Apr 2013
246===========
247
0a2956ab
TC
248 - handle the SVf_UTF8 flag correctly on magic strings passed to
249 Imager::IO's write() and raw_write() methods.
250 This may misbehave in perl 5.6.x since the UTF8 flag may not be
251 visible in the main SV after SvGETMAGIC().
252 https://rt.cpan.org/Ticket/Display.html?id=83438
253
254 - document that bounding_box() ignores the transformation matrix
255 supplied to tranform() for fonts.

TC
258Imager 0.94_02 - 5 Apr 2013
259==============
260
1540d1d4
TC
261 - enable debug logging for the standard font tests
262
263 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
264 due to a bug in that version of perl.
265
266 - don't test for read() failing on a write-only handle in 5.8.x and
267 earlier, this was fixed in change 862083f7e4 in perl.
268
269 - report the version of Inline found during testing (an attempt to
270 diagnose some intermittent failures.)

TC
272Imager 0.94_01 - 2 Mar 2013
273==============
274
14a4ea18 275 - NOTE: possibly backward incompatible:
3dcf7595
TC
276 support reading from/writing to perl filehandes that aren't raw
277 files.
278
279 This allows Imager's I/O to honour handles with layers such as
280 gzip, scalar file handles or tied file handles.
281
14a4ea18 282 This is backward incompatible in that previous Imager would simply
3dcf7595
TC
283 use fileno() to retrieve the fd for the file and call write(2) etc
284 on it directly.
04d8c568
TC
285 https://rt.cpan.org/Ticket/Display.html?id=78843
286
287 - moved most of README to lib/Imager/Install.pod which should make it
288 more accessible to the "web" generation, also significantly updated
289 and re-worked it.
3dcf7595 290
ca96f811
TC
291 - updated README's for the separately distributed modules to refer to
292 Imager::Install, and that they need -dev versions of packages
293 https://rt.cpan.org/Ticket/Display.html?id=81265
294
26e8a226
TC
295 - the JPEG test code now reports the compile-time library version
296

305 https://rt.cpan.org/Ticket/Display.html?id=82743
41125e7d 306
c732ffa5
TC
307 - drawing text to a channel with FT2 would draw with random coverage
308 due to an uninitialized alpha channel.
309
310 - marked the function pointer underlying the mm_log() API with the
311 correct gcc magic and fixed the resulting warnings.
312
313 - fixed some other compiler warnings
314
14a4ea18
TC
315 - Imager::Font::W32 now properly reports text drawing errors
316 https://rt.cpan.org/Ticket/Display.html?id=70098
317
0a2956ab 318 - handle the SVf_UTF8 flag correctly on magic (eg. overloaded)
14a4ea18
TC
319 strings passed as text to draw(), bounding_box(), has_chars(),
320 glyph_names() (where supported) in each of the font drivers.
0a2956ab
TC
321 This may misbehave in perl 5.6.x since the UTF8 flag may not be
322 visible in the main SV after SvGETMAGIC().

325Imager 0.94 - 15 Dec 2012
326=========================
327
328Variations on some of these changes were included in development
329releases.
330
4be61824
TC
331 - improved thread safety
332 - the internal error stack and log file handle are now in a per-thread
333 context object
334 - JPEG now captures IPTC information in a thread-safe way
335 - avoid globals where possible for warning capture in libtiff
244725cf
TC
336 - use a mutex to avoid re-entering thread-unsafe giflib
337 - use a mutex to avoid re-entering thread-unsafe tifflib
338 - use a mutex to avoid re-entering thread-unsafe T1Lib

356===========
357
358Bug fixes:
71fbe41a
TC
359
360 - previously a transparency enabled GIF write (the default) would
361 always use a GIF89a header even if none of the images were
362 transparent.
7a5f7bc6 363
b2f967ef
TC
364 - previously the probe step for freetype-config would fail on cygwin

383Enhancements:
384
385 - support for giflib 5.0. (5.0.1 and later)
386 https://rt.cpan.org/Ticket/Display.html?id=79029
387 The giflib API Imager uses doesn't have a mechanism to set the
388 header version in 5.0.0.
389
390 - update the GIF library probe code to check for the new giflib 5.0.1
391 EGifSetGifVersion() function, and to check for the giflib 4.2.0
392 uninitialized gif89 bug.
393 https://rt.cpan.org/Ticket/Display.html?id=79679
394 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
395
396 - avoid static variables when capturing IPTC data from JPEG files
397
398 - match Imager::Font;:T1's error message translations to those from
399 later versions of T1Lib.
400
401 - for libtiff versions that support extended warning handlers (3.8.0
402 or later), use them to avoid some global variables.
403
404 - note Image::ExifTool for better metadata support.

410 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
411 correctly for both probing and runtime.

38742a13 422
289d65f4
TC
423 - The size of rotated images is no longer rounded up so aggressively.
424 Added rounding to the linear interpolation done for rotate() and
425 matrix_transform() for 1 and 3 channel 8-bit images.
426 Adjusted the two tranlate matrices used to build the final rotation
427 matrix to use the distance between the outlier pixels rather than
428 the pixel dimensions (ie. dimension-1).
429 With all of this the output of rotate(degrees => 270) on an 8-bit
430 image exactly matches the output of rotate(right => 270).
431 https://rt.cpan.org/Ticket/Display.html?id=77063
432
ef84bb32
TC
433Other changes:
434
435 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
436 internals, those names only matter for the XS interface.
437
438 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
439 the API level compiled into a loadable module such as
440 Imager::File::GIF doesn't match that of Imager. Previously it
441 could be difficult to determine exactly which module was failing to
442 load.
443 https://rt.cpan.org/Ticket/Display.html?id=77173

455===========
456
457Bug fixes:
458
459 - Imager::Test::is_imaged() attempted to process an "epsilon"
460 parameter but the prototype didn't allow for the extra parameter.
461 Corrected the prototype.

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

471 - BI_BITFIELD BMP images were handled incorrectly, both in
472 incorrectly calculating the space required for the masks and in
473 processing the image data itself.
474 https://rt.cpan.org/Ticket/Display.html?id=76736
475
476 - some odd width BMP BI_RLE4 images use run lengths that run one off
477 the edge of the image. Imager now allows this, discarding the
478 extra column.
479
480 - odd length RLE4 runs in BMP images were decoded incorrectly.

490 common for static linking, eg. libpng requires libz.
491 https://rt.cpan.org/Ticket/Display.html?id=74043
492
493 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.

496 handle a statically linked libpng.
497 https://rt.cpan.org/Ticket/Display.html?id=74043
498
499 - if a probe includes testcode, Imager::Probe now checks that code as
500 part of the process of checking each configuration rather than as a
501 post test of the found configuration. This allows alternate
502 configurations to be checked if a matching but non-working
503 configuration is found.

741 - io_glue I/O buffering re-work:
742
743 - reorganize io_glue to do it's own buffering by default
744
745 - the unbuffered functions are available as i_io_raw_read() (or
746 raw_read() from perl) etc but are not recommended for typical
747 use.
748
749 - use the new i_io_peekn() when checking for file magic to avoid
750 seek, allowing Imager to detect the file type and read the file
751 from an unseekable stream (for formats that don't use random
752 access)
753
754 - added several new I/O layer API functions.

759 - TIFF now uses wrapper functions of the correct types to avoid casts
760 https://rt.cpan.org/Ticket/Display.html?id=69912
761
762 - the callback IO object did its own buffering, controlled by the
763 maxbuffer parameter supplied to the read() and write() methods.
764 This buffering has been removed, to avoid redundancy with the
765 common io_glue buffering. This also avoids a bug in that code
766 which could rarely pass a zero length to the read callback and
767 then panic about the result.
768
769 - the callback IO object now tests the result of calling the close
770 callback, which should return true for success.
771
772 - the PNM reader did its own buffering. This buffering has been
773 removed to avoid redundancy with the common io_glue buffering.
774
775 - previously the read handlers for fd and callback I/O layers would
776 call the underlying interface (POSIX read or your supplied callback)
777 until it filled the buffer. It now only makes one call.
778
779 - added public constructors for I/O layer objects (see Imager::IO)
780
781 - all core file handlers now use the i_io_foo() wrappers to gain
782 access to buffered I/O rather than calling the I/O layer
783 callbacks directly.
784
785 - all core file handlers now check for error on close.
786
787 - Backward compatibility: if you hava custom file handlers, you can
788 use i_io_write() etc since they're available as macros in older
789 versions of Imager.
790
791 - eliminate the final remnants of io_glue_commit_types().
792
793 - bump IMAGER_API_VERSION, since the above may break assumptions.
794
795 - removed the long unused i_gen_reader() and i_gen_writer() utility
796 functions.

859Development release as a sanity check for the types re-work.

TC
860
861Massive types re-work:
862
863 - the type used internally for pixel co-ordinates and image sizes is
864 now 64-bit on 64-bit platforms (at least sane ones).
865
866 - size_t is now used consistently for memory block sizes.
867
868 - since this changes the binary interface, the Imager API version has
869 been incremented. Any module that uses the API will need to be
870 rebuilt. In most cases that will be enough, but calls to any APIs
871 that take a pointer to image sizes may need source changes.
872
873 - you should be able to create very large images on 64-bit systems,
874 if you have enough memory. Successfully created a 32768 x 49192 x
875 3 channel image, filled with a tiled image and scaled it. The
876 unscaled image was also successfully saved to a JPEG.
877
878 - check the image size before attempting to write BMP, GIF, JPEG,
879 PNG, SGI, TGA, TIFF images.
880
881 - correctly handle reading TGA images over 32767 pixels wide or tall.
882
883Incidental changes:
884
885 - the gif_left and gif_top tags are now clamped to non-negative
886 values when writing a GIF image.
887

889
890The default maximum memory size when reading files is now 1G.

1337 - the conv filter now enforces that the sum of the coefficients is
1338 non-zero. Also, rather than skipping pixels off the edge off the
1339 edge of the image, the closest edge pixel is used. Previously
1340 dividing by the zero sum of coefficients could cause invalid
1341 results or runtime exceptions.

1537 - moved the imtoc.perl code into Imager::Preprocess

1542 noalpha channels or back.
1543 https://rt.cpan.org/Ticket/Display.html?id=30908
1544
1545 - rubthrough() now falls back to pasting when the source doesn't have
1546 an alpha channel. This effectively treats the source as having a
1547 max alpha channel, the right thing to do.
1548 http://rt.cpan.org/Ticket/Display.html?id=29944
1549
1550 - re-worked most of the area filling code to use a common set of

1553 Rewrote most of the combine modes to match the way the SVG draft
1554 defines them with respect to a translucent source and destination.

1557 similarly.

1598 being set was treated as an opaque pixel, but one user reported a
1599 problem with loading such an image. I haven't been able to find any
1600 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1601 I'll match it's behaviour. See issue 114913 in the GIMP's
1602 bugzilla.

1759 - the mask for ICO/CUR images is now applied as an alpha channel to
1760 the returned image. For the old behaviour, supply ico_masked => 0
1761 to read() or read_multi(). This should be less confusing when
1762 using Imager as a general image processor.

1765Bug fixes:

1767 - in some cases it's possible for giflib/libungif to return color
1768 indexes outside the range of colors defined by the image's palette.
1769 We now expand the palette to match the indexes used.
1770 Thanks to Gabriel Vasseur for reporting this.

1775 - to avoid confusion, channels not present in the image are returned as
1776 zero by getscanline(). This has no effect on the C level i_glin()

1778 channels.

1920Imager 0.55 - 16 Dec 2006
1921===========
1922
1923This is primarily a bug fix release.
1924
1925Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1926
1927There is one new feature:
1928
1929 - the Win32 font driver now supports UTF8 (RT 22166)
1930 http://www.cpanforum.com/threads/3276
1931 http://rt.cpan.org/Ticket/Display.html?id=22166
1932
1933Several bugs were fixed:
1934
1935 - the string() method would not output the string "0"
1936 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1937
1938 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1939 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1940
1941 - the gif_disposal and gif_user_input tags weren't being read from
1942 the file correctly
1943 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1944
1945 - gif.c was failing to build under MSVC
1946 http://rt.cpan.org/Ticket/Display.html?id=23922
1947
1948 - in some cases strings passed to the string() method were treated as
1949 terminated by NUL (chr 0)
1950 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1951
1952 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1953 that's the default build name for zlib on Win32.
1954 http://rt.cpan.org/Ticket/Display.html?id=23064
1955
1956 - search $Config{incpath} for headers too, which we should have been
1957 doing all along.
1958
1959Win32 font driver fixes:
1960
1961 - the global descent value from bounding box was the wrong sign
1962 http://www.cpanforum.com/threads/3276
1963
1964 - if the first or last glyph overflowed the left or right side of the
1965 advance width they would be clipped
1966
1967
1968Imager 0.54 - 14 Sep 2006
1969===========
1970
1971This is primarily a feature release:
1972
1973 - a new qtype value 'mixing' has been added to the scale()
1974 method. This is faster than 'normal', slower than 'preview'. This
1975 is based on the method used by pnmscale, and seems to produce less
1976 blurry results than normal.
1977 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1978
1979 - the rubthrough() method can now render onto images with an alpha
1980 channel.
1981 http://rt.cpan.org/Ticket/Display.html?id=20678
1982
1983 - the read_multi() method now falls back to calling doing a single
1984 image read via the read() method and write_multi() will now fall
1985 back to calling write() if a single image is supplied. This means
1986 you can simply call the read_multi() or write_multi() functions
1987 without having to check if the type is formatted by that method.
1988 http://rt.cpan.org/Ticket/Display.html?id=19457
1989 http://rt.cpan.org/Ticket/Display.html?id=19458
1990
1991 - the GIF loop extension can now be written. If you don't have
1992 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1993 should upgrade.
1994 http://rt.cpan.org/Ticket/Display.html?id=21185
1995
1996 - getscanline() and setscanline() can now read/write palette index
1997 based data from/to the image for paletted images, by setting type to
1998 'index'.
1999 http://rt.cpan.org/Ticket/Display.html?id=20338
2000
2001 - we no longer hassle you to disable GIF support
2002 http://rt.cpan.org/Ticket/Display.html?id=20687
2003
2004 - minor documentation fixes
2005
2006
2007Imager 0.53 - 26 Jul 2006
2008===========
2009
2010This is a bugfix release.
2011
2012Some test code was left in a code path not covered by the test
2013suite. A test was added to cover this code path and the test code was
2014removed.

2017
2018Imager 0.52 - 25 Jul 2006
2019===========
2020
2021This is primarily a feature release, but contains a fair few bug
2022fixes, new features:
2023
2024 - ability to read and write MS Windows ICO and CUR files
2025
2026 - you can now add file format plugins to support new file formats
2027
2028 - add POD coverage tests
2029
2030 - setcolors() and addcolors() now accept color names and so on
2031 instead of requiring Imager::Color objects.
2032 http://rt.cpan.org/Ticket/Display.html?id=20056
2033
2034 - flood_fill() can now fill to a specified border color instead of
2035 just to the area the same color as the seed.
2036 http://rt.cpan.org/Ticket/Display.html?id=19618
2037
2038
2039Bug fixes:
2040
2041 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2042 calculating the advance width.
2043 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2044
2045 - bounding_box for the T1 driver wasn't including leading and
2046 trailing spaces in the bounding box as the other drivers did, it also
2047 produced strange results for empty strings or strings containing only
2048 spaces
2049
2050 - when reading CMYK jpeg images they were being transferred to the
2051 image object as is, producing a four channel image. It only looked ok
2052 due to an old still unfixed Photoshop bug. We now convert from the
2053 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2054 http://rt.cpan.org/Ticket/Display.html?id=20416
2055
2056 - reading a CYMK TIFF would result in a 4 channel image, reading any
2057 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2058 result in an error.
2059 http://rt.cpan.org/Ticket/Display.html?id=20415
2060
2061 - added /usr/local/include to the default include search path, since
2062 we were already searching /usr/local/lib for libraries.
2063
2064And various minor fixes and documentation updates.
2065
2066
2067Imager 0.51 - 23 Apr 2006

2088 output is an in-memeory buffer.
