10 - GIF: avoid a double-free when do_write() fails.
11
28104a85 12 - fix SV type probing to work on perl before 5.12. Broken in 0.99.

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

20===========
21
dce1523b
TC
22 - Imager::IO->new_buffer() (and hence Imager->read()'s data
23 parameter) now accepts a reference to a scalar as well as just a
24 plain scalar.
6a160bce 25 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
26
27 - Imager::IO->new_buffer() now always makes a copy of the passed in
28 buffer to avoid problems with temporary objects used for the return
29 value of SvPVbyte().
6a160bce 30 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 31
c757e211
TC
32 - improved the XS for i_io_read() and i_io_raw_read()
33 https://rt.cpan.org/Ticket/Display.html?id=92738
34
35 - load plugins from absolute paths on Android
36 Thanks to Brian Fraser.
37 https://rt.cpan.org/Ticket/Display.html?id=93272
38
6a160bce
TC
39 - added the jpeg_optimize parameter for writing JPEG files. This can
40 significantly reduce file sizes, but uses more memory and time.
41 https://rt.cpan.org/Ticket/Display.html?id=94292
42
14fd9e5d
TC
43 - the autolevels filter now works on the luminosity of the image
44 rather then working per channel. The old autolevels filter is
45 still available as "autolevels_skew".
46 https://rt.cpan.org/Ticket/Display.html?id=94413
47
75d54149
TC
48 - Imager::File::PNG now supports libpng 1.6.10.
49 1.6.10 changed CRC errors from benign errors to normal errors,
50 which broke the test which used CRC errors to check for benign
51 error support. Switched to using a 1-bit grey-scale image with a
52 palette to test for benign errors.

55Imager 0.98 - 3 Jan 2014
56===========
57
f84f86a2
TC
58Incompatible changes:
59
60 - the return value of setpixel() has changed.
61
62 Previously the return values for undrawable pixels vs caller errors
63 changed depending on whether you used the multiple pixel calling
64 mechanism, or the single pixel mechanism.
65
66 Now:
67
68 - for an invalid parameter, such as an unknown colour, or missing
69 parameter, an empty list (or undef in scalar context) is
70 returned, and errstr() is set,
71
72 - otherwise the number of pixels drawn is returned. If none of
73 the pixels could be drawn (they were all outside the image), "0
74 but true" is returned.
75
76 https://rt.cpan.org/Ticket/Display.html?id=87650
77
78Other changes:
79
6ba09ab9
TC
80 - when drawing on an image with an alpha channel where the source
81 minimum is greater than zero, Imager would read from beyond the end
82 of a malloc() allocated buffer. In rare circumstances this could
83 lead to some of the source image not being written to the target
84 image, or possibly to a segmentation fault.
85 I don't believe this has any security concerns beyond that.
86
0d052fd9
TC
87 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
88 text drawn would be nonsense. This would also read beyond the end
89 of a malloced buffer.
90
13671b17
TC
91 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
92 truncated early.
93 https://rt.cpan.org/Ticket/Display.html?id=88993
94
d6f4e964
TC
95 - Imager::Font::Wrap no longer requires the image parameter.
96 https://rt.cpan.org/Ticket/Display.html?id=87338
97
f84f86a2
TC
98 - a documentation typo fix in Imager::Transformations
99 Thanks to Adrian Yee.
100 https://rt.cpan.org/Ticket/Display.html?id=88598
101
0179ecd6
TC
102 - Image::Probe, Imager's internal module for probing library
103 locations now searches the directories specified by LD_RUN_PATH,
104 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
105 and the corresponing s/\blib$/include/ directories for header
106 files.

TC
114Imager 0.96_02 - 8 Jul 2013
115==============
116
aaf82685
TC
117 - PNG: treat a version mismatch between headers and library as a
118 probe failure.
119 https://rt.cpan.org/Ticket/Display.html?id=86659
120
8e90f677
TC
121 - PNG: the check for benign error support is more complex than a
122 simple library version check, check for the appropriate macro.
123 Thanks for Slaven Rezic for following up on my CPAN Testers result
124 queries.
125 https://rt.cpan.org/Ticket/Display.html?id=86659

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

TC
131==============
132
05c9b356
TC
133 - TIFF: handle SampleFormat = 2 by translating the signed integer
134 values to unsigned by flipping their sign bits.
135
136 Handle SampleFormat = 3 where possible.
137
138 SampleFormat is ignored for paletted images.
139
237d9e03
TC
140 Mixed SampleFormat are handled incorrectly, since libtiff returns
141 only the first SampleFormat value, and an image with both an alpha
142 channel and SampleFormat = 2 for color channels probably has a
143 different SampleFormat for the alpha channel.

face45e7 147 - XS clean up:
29969fa2 148 https://rt.cpan.org/Ticket/Display.html?id=69243
face45e7 149
237d9e03 150 - Imager::Color's rgba() method now returns its values as integers
face45e7
TC
151 instead of floating point. (IV instead of NV).
152
19e9591b
TC
153 - The XS for i_map() and i_matrix_transform() now use the AV *
154 typemap instead of rolling their own.
155
75cebca8
TC
156 - The XS for DSO_call() now uses the HV * typemap instead of
157 rolling it's own.
158
0aaa8b4d
TC
159 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
160 i_gradgen() now use a new T_AVARRAY typemap that greatly
161 simplifies the XS code.
face45e7 162
ccd01d49
TC
163 - many other minor XS changes
164
face45e7 165 - some XS code formatting
a54e32ba 166
dcab59bc
TC
167 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
168 now renders in alpha-combining mode, to match antialiased output.
169 https://rt.cpan.org/Ticket/Display.html?id=73359
b482243a 170
8db7b6fa
TC
171 - add sample code and cookbook notes for drawing a blurred drop-shadow.
172
173 - add support for libpng 1.6, which changed the defaults for
174 reporting some types of error.
175 https://rt.cpan.org/Ticket/Display.html?id=85746
176
dc076f98
TC
177 - FT2: use gsamp/psamp() to transfer pixels from the work image to
178 the output image instead of gpix/ppix.
179 https://rt.cpan.org/Ticket/Display.html?id=83478
180
98747309
TC
181 - eliminate various GCC warnings, mostly initialized but otherwise
182 unused variables.

184Imager 0.96 - 19 May 2013
185===========
186
c2e251d9
TC
187 - rearrange Imager's test files.
188 https://rt.cpan.org/Ticket/Display.html?id=84596
189
190 - Imager::Probe::_gcc_lib_paths now forces C locale.
191 A sufficiently recent gcc prints localized keys for the search
192 paths, which avoids that localization.
193 https://rt.cpan.org/Ticket/Display.html?id=84963
194
195 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
196 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
197 and true.
198 https://rt.cpan.org/Ticket/Display.html?id=85262
199 reported by Andreas König
200
201 - add a test for unclosed POD in C source, and fix the errors it
202 found.
203 https://rt.cpan.org/Ticket/Display.html?id=74875
204
205 - fix some spelling errors detected by the newer aspell in Debian
206 Wheezy.
207
208 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
209 thanks to gregor herrmann <gregoa@debian.org>
210 https://rt.cpan.org/Ticket/Display.html?id=85413

TC
214Imager 0.95 - 19 Apr 2013
215===========
216
0a2956ab
TC
217 - handle the SVf_UTF8 flag correctly on magic strings passed to
218 Imager::IO's write() and raw_write() methods.
219 This may misbehave in perl 5.6.x since the UTF8 flag may not be
220 visible in the main SV after SvGETMAGIC().
221 https://rt.cpan.org/Ticket/Display.html?id=83438
222
223 - document that bounding_box() ignores the transformation matrix
224 supplied to tranform() for fonts.

TC
227Imager 0.94_02 - 5 Apr 2013
228==============
229
1540d1d4
TC
230 - enable debug logging for the standard font tests
231
232 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
233 due to a bug in that version of perl.
234
235 - don't test for read() failing on a write-only handle in 5.8.x and
236 earlier, this was fixed in change 862083f7e4 in perl.
237
238 - report the version of Inline found during testing (an attempt to
239 diagnose some intermittent failures.)

TC
241Imager 0.94_01 - 2 Mar 2013
242==============
243
14a4ea18 244 - NOTE: possibly backward incompatible:
3dcf7595
TC
245 support reading from/writing to perl filehandes that aren't raw
246 files.
247
248 This allows Imager's I/O to honour handles with layers such as
249 gzip, scalar file handles or tied file handles.
250
14a4ea18 251 This is backward incompatible in that previous Imager would simply
3dcf7595
TC
252 use fileno() to retrieve the fd for the file and call write(2) etc
253 on it directly.
04d8c568
TC
254 https://rt.cpan.org/Ticket/Display.html?id=78843
255
256 - moved most of README to lib/Imager/Install.pod which should make it
257 more accessible to the "web" generation, also significantly updated
258 and re-worked it.
3dcf7595 259
ca96f811
TC
260 - updated README's for the separately distributed modules to refer to
261 Imager::Install, and that they need -dev versions of packages
262 https://rt.cpan.org/Ticket/Display.html?id=81265
263
26e8a226
TC
264 - the JPEG test code now reports the compile-time library version
265
41125e7d
TC
266 - avoid a possible compiler optimization issue on CentOS 5.9 i386 by
267 rearranging (and mildly optimizing) some code.

272
273 - fix a broken link to Graphics::Magick
274 https://rt.cpan.org/Ticket/Display.html?id=82743
41125e7d 275
c732ffa5
TC
276 - drawing text to a channel with FT2 would draw with random coverage
277 due to an uninitialized alpha channel.
278
279 - marked the function pointer underlying the mm_log() API with the
280 correct gcc magic and fixed the resulting warnings.
281
282 - fixed some other compiler warnings
283
14a4ea18
TC
284 - Imager::Font::W32 now properly reports text drawing errors
285 https://rt.cpan.org/Ticket/Display.html?id=70098
286
0a2956ab 287 - handle the SVf_UTF8 flag correctly on magic (eg. overloaded)
14a4ea18
TC
288 strings passed as text to draw(), bounding_box(), has_chars(),
289 glyph_names() (where supported) in each of the font drivers.
0a2956ab
TC
290 This may misbehave in perl 5.6.x since the UTF8 flag may not be
291 visible in the main SV after SvGETMAGIC().

294Imager 0.94 - 15 Dec 2012
295=========================
296
297Variations on some of these changes were included in development
298releases.
299
4be61824
TC
300 - improved thread safety
301 - the internal error stack and log file handle are now in a per-thread
302 context object
303 - JPEG now captures IPTC information in a thread-safe way
304 - avoid globals where possible for warning capture in libtiff
244725cf
TC
305 - use a mutex to avoid re-entering thread-unsafe giflib
306 - use a mutex to avoid re-entering thread-unsafe tifflib
307 - use a mutex to avoid re-entering thread-unsafe T1Lib
308 - use a library handle per thread for freetype 2.
0124c060 309 - use an engine handle per thread for freetype 1.x.
0eebfd59

324Imager 0.93 - 15 Oct 2012
325===========
326
327Bug fixes:
71fbe41a
TC
328
329 - previously a transparency enabled GIF write (the default) would
330 always use a GIF89a header even if none of the images were
331 transparent.
7a5f7bc6 332
b2f967ef
TC
333 - previously the probe step for freetype-config would fail on cygwin
334

TC
335 - catch an invalid matrix parameter to convert() instead of crashing
336 https://rt.cpan.org/Ticket/Display.html?id=79922
337
338 - remove the 16-bit/sample limitation from the documentation for
339 setsamples(), it hasn't applied for many releases.
340 https://rt.cpan.org/Ticket/Display.html?id=79989
341
9673d97e

351
e9daa5af
TC
352Enhancements:
353
354 - support for giflib 5.0. (5.0.1 and later)
355 https://rt.cpan.org/Ticket/Display.html?id=79029
356 The giflib API Imager uses doesn't have a mechanism to set the
357 header version in 5.0.0.
358
359 - update the GIF library probe code to check for the new giflib 5.0.1
360 EGifSetGifVersion() function, and to check for the giflib 4.2.0
361 uninitialized gif89 bug.
362 https://rt.cpan.org/Ticket/Display.html?id=79679
363 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
364
365 - avoid static variables when capturing IPTC data from JPEG files
366
367 - match Imager::Font;:T1's error message translations to those from
368 later versions of T1Lib.
369
370 - for libtiff versions that support extended warning handlers (3.8.0
371 or later), use them to avoid some global variables.
372
373 - note Image::ExifTool for better metadata support.

TC
379 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
380 correctly for both probing and runtime.
381 https://rt.cpan.org/Ticket/Display.html?id=77672
382

388===========
389
ef84bb32 390Bug fixes:
38742a13 391
289d65f4
TC
392 - The size of rotated images is no longer rounded up so aggressively.
393 Added rounding to the linear interpolation done for rotate() and
394 matrix_transform() for 1 and 3 channel 8-bit images.
395 Adjusted the two tranlate matrices used to build the final rotation
396 matrix to use the distance between the outlier pixels rather than
397 the pixel dimensions (ie. dimension-1).
398 With all of this the output of rotate(degrees => 270) on an 8-bit
399 image exactly matches the output of rotate(right => 270).
400 https://rt.cpan.org/Ticket/Display.html?id=77063
401
ef84bb32
TC
402Other changes:
403
404 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
405 internals, those names only matter for the XS interface.
406
407 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
408 the API level compiled into a loadable module such as
409 Imager::File::GIF doesn't match that of Imager. Previously it
410 could be difficult to determine exactly which module was failing to
411 load.
412 https://rt.cpan.org/Ticket/Display.html?id=77173
413
414 - added Imager->check_file_limits() as an interface to the
415 i_int_check_image_file_limits() API.
416
417 - Imager->set_file_limits(reset => 1) now resets the limits to the
418 defaults rather than setting them all to unlimited.
419
420 - wrote a brief security note as Imager::Security

7c4464f5
TC
424===========
425
426Bug fixes:
427
428 - Imager::Test::is_imaged() attempted to process an "epsilon"
429 parameter but the prototype didn't allow for the extra parameter.
430 Corrected the prototype.
431
29b38678
TC
432 - when downconverting samples (eg. from floating point to 8 bit)
433 Imager now rounds the sample value rather than attempting to
434 allocate input values over output values equally. The old
435 behaviour had the probably surprising effect of converting a
436 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
437 2.
438 This may result in slightly different 8 or 16-bit output images.
439
e2a86bac
TC
440 - BI_BITFIELD BMP images were handled incorrectly, both in
441 incorrectly calculating the space required for the masks and in
442 processing the image data itself.
443 https://rt.cpan.org/Ticket/Display.html?id=76736
444
445 - some odd width BMP BI_RLE4 images use run lengths that run one off
446 the edge of the image. Imager now allows this, discarding the
447 extra column.
448
449 - odd length RLE4 runs in BMP images were decoded incorrectly.

458 - Imager::Probe can now probe for libraries with dependent libraries,
459 common for static linking, eg. libpng requires libz.
460 https://rt.cpan.org/Ticket/Display.html?id=74043
461
462 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.

465 handle a statically linked libpng.
466 https://rt.cpan.org/Ticket/Display.html?id=74043
467
468 - if a probe includes testcode, Imager::Probe now checks that code as
469 part of the process of checking each configuration rather than as a
470 post test of the found configuration. This allows alternate
471 configurations to be checked if a matching but non-working
472 configuration is found.

710 - io_glue I/O buffering re-work:
711
712 - reorganize io_glue to do it's own buffering by default
713
714 - the unbuffered functions are available as i_io_raw_read() (or
715 raw_read() from perl) etc but are not recommended for typical
716 use.
717
718 - use the new i_io_peekn() when checking for file magic to avoid
719 seek, allowing Imager to detect the file type and read the file
720 from an unseekable stream (for formats that don't use random
721 access)
722
723 - added several new I/O layer API functions.
724
725 - fix the TGA performance problem, most noticably on Win32
726 https://rt.cpan.org/Ticket/Display.html?id=70037
727
728 - TIFF now uses wrapper functions of the correct types to avoid casts
729 https://rt.cpan.org/Ticket/Display.html?id=69912
730
731 - the callback IO object did its own buffering, controlled by the
732 maxbuffer parameter supplied to the read() and write() methods.
733 This buffering has been removed, to avoid redundancy with the
734 common io_glue buffering. This also avoids a bug in that code
735 which could rarely pass a zero length to the read callback and
736 then panic about the result.
737
738 - the callback IO object now tests the result of calling the close
739 callback, which should return true for success.
740
741 - the PNM reader did its own buffering. This buffering has been
742 removed to avoid redundancy with the common io_glue buffering.
743
744 - previously the read handlers for fd and callback I/O layers would
745 call the underlying interface (POSIX read or your supplied callback)
746 until it filled the buffer. It now only makes one call.
747
748 - added public constructors for I/O layer objects (see Imager::IO)
749
750 - all core file handlers now use the i_io_foo() wrappers to gain
751 access to buffered I/O rather than calling the I/O layer
752 callbacks directly.
753
754 - all core file handlers now check for error on close.
755
756 - Backward compatibility: if you hava custom file handlers, you can
757 use i_io_write() etc since they're available as macros in older
758 versions of Imager.
759
760 - eliminate the final remnants of io_glue_commit_types().
761
762 - bump IMAGER_API_VERSION, since the above may break assumptions.
763
764 - removed the long unused i_gen_reader() and i_gen_writer() utility
765 functions.

828Development release as a sanity check for the types re-work.
8d14daab
TC
829
830Massive types re-work:
831
832 - the type used internally for pixel co-ordinates and image sizes is
833 now 64-bit on 64-bit platforms (at least sane ones).
834
835 - size_t is now used consistently for memory block sizes.
836
837 - since this changes the binary interface, the Imager API version has
838 been incremented. Any module that uses the API will need to be
839 rebuilt. In most cases that will be enough, but calls to any APIs
840 that take a pointer to image sizes may need source changes.
841
842 - you should be able to create very large images on 64-bit systems,
843 if you have enough memory. Successfully created a 32768 x 49192 x
844 3 channel image, filled with a tiled image and scaled it. The
845 unscaled image was also successfully saved to a JPEG.
846
847 - check the image size before attempting to write BMP, GIF, JPEG,
848 PNG, SGI, TGA, TIFF images.
849
850 - correctly handle reading TGA images over 32767 pixels wide or tall.
851
852Incidental changes:
853
854 - the gif_left and gif_top tags are now clamped to non-negative
855 values when writing a GIF image.
856
857 - removed dead callback read/write code
858
859The default maximum memory size when reading files is now 1G.

1497This release primarily contains changes to improve ease of use -
1498rather than you having to convert images to the appropriate number of

1501release.

TC
1506 - moved the imtoc.perl code into Imager::Preprocess
1507
1508 - paste() and rubthrough() now adapt the source image data to the
1509 destination, so you can now safely paste/rubthrough from greyscale
1510 images to color images or back, or from alpha channel images to
1511 noalpha channels or back.
1512 https://rt.cpan.org/Ticket/Display.html?id=30908
1513
1514 - rubthrough() now falls back to pasting when the source doesn't have
1515 an alpha channel. This effectively treats the source as having a
1516 max alpha channel, the right thing to do.
1517 http://rt.cpan.org/Ticket/Display.html?id=29944
1518
1519 - re-worked most of the area filling code to use a common set of
1520 functions when filling.
1521 Corrected normal combine mode.
1522 Rewrote most of the combine modes to match the way the SVG draft
1523 defines them with respect to a translucent source and destination.
1524 Added tests for translucent source and destination.
1525 Added tests to check 8-bit/sample and double/sample combines work
1526 similarly.

1565 - handling of the left-over bit for 16-bit/pixel TGA images has been
1566 changed to match the behaviour of the GIMP. Previously the bit
1567 being set was treated as an opaque pixel, but one user reported a
1568 problem with loading such an image. I haven't been able to find any
1569 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1570 I'll match it's behaviour. See issue 114913 in the GIMP's
1571 bugzilla.

1581 - the old dynaload code used Mach API functions to load dynamic
1582 libraries on Mac OS X. These APIs have been deprecated in OS X
1583 10.5 and were causing some build problems.

1889Imager 0.55 - 16 Dec 2006
1890===========
1891
1892This is primarily a bug fix release.
1893
1894Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1895
1896There is one new feature:
1897
1898 - the Win32 font driver now supports UTF8 (RT 22166)
1899 http://www.cpanforum.com/threads/3276
1900 http://rt.cpan.org/Ticket/Display.html?id=22166
1901
1902Several bugs were fixed:
1903
1904 - the string() method would not output the string "0"
1905 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1906
1907 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1908 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1909
1910 - the gif_disposal and gif_user_input tags weren't being read from
1911 the file correctly
1912 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1913
1914 - gif.c was failing to build under MSVC
1915 http://rt.cpan.org/Ticket/Display.html?id=23922
1916
1917 - in some cases strings passed to the string() method were treated as
1918 terminated by NUL (chr 0)
1919 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1920
1921 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1922 that's the default build name for zlib on Win32.
1923 http://rt.cpan.org/Ticket/Display.html?id=23064
1924
1925 - search $Config{incpath} for headers too, which we should have been
1926 doing all along.
1927
1928Win32 font driver fixes:
1929
1930 - the global descent value from bounding box was the wrong sign
1931 http://www.cpanforum.com/threads/3276
1932
1933 - if the first or last glyph overflowed the left or right side of the
1934 advance width they would be clipped
1935
1936
1937Imager 0.54 - 14 Sep 2006
1938===========
1939
1940This is primarily a feature release:
1941
1942 - a new qtype value 'mixing' has been added to the scale()
1943 method. This is faster than 'normal', slower than 'preview'. This
1944 is based on the method used by pnmscale, and seems to produce less
1945 blurry results than normal.
1946 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1947
1948 - the rubthrough() method can now render onto images with an alpha
1949 channel.
1950 http://rt.cpan.org/Ticket/Display.html?id=20678
1951
1952 - the read_multi() method now falls back to calling doing a single
1953 image read via the read() method and write_multi() will now fall
1954 back to calling write() if a single image is supplied. This means
1955 you can simply call the read_multi() or write_multi() functions
1956 without having to check if the type is formatted by that method.
1957 http://rt.cpan.org/Ticket/Display.html?id=19457
1958 http://rt.cpan.org/Ticket/Display.html?id=19458
1959
1960 - the GIF loop extension can now be written. If you don't have
1961 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1962 should upgrade.
1963 http://rt.cpan.org/Ticket/Display.html?id=21185
1964
1965 - getscanline() and setscanline() can now read/write palette index
1966 based data from/to the image for paletted images, by setting type to
1967 'index'.
1968 http://rt.cpan.org/Ticket/Display.html?id=20338
1969
1970 - we no longer hassle you to disable GIF support
1971 http://rt.cpan.org/Ticket/Display.html?id=20687
1972
1973 - minor documentation fixes
1974
1975
1976Imager 0.53 - 26 Jul 2006
1977===========
1978
1979This is a bugfix release.
1980
1981Some test code was left in a code path not covered by the test
1982suite. A test was added to cover this code path and the test code was
1983removed.
1984http://rt.cpan.org/Public/Bug/Display.html?id=20705
1985
1986
1987Imager 0.52 - 25 Jul 2006
1988===========
1989
1990This is primarily a feature release, but contains a fair few bug
1991fixes, new features:
1992
1993 - ability to read and write MS Windows ICO and CUR files
1994
1995 - you can now add file format plugins to support new file formats
1996
1997 - add POD coverage tests
1998
1999 - setcolors() and addcolors() now accept color names and so on
2000 instead of requiring Imager::Color objects.
2001 http://rt.cpan.org/Ticket/Display.html?id=20056
2002
2003 - flood_fill() can now fill to a specified border color instead of
2004 just to the area the same color as the seed.
2005 http://rt.cpan.org/Ticket/Display.html?id=19618
2006
2007
2008Bug fixes:
2009
2010 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2011 calculating the advance width.
2012 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2013
2014 - bounding_box for the T1 driver wasn't including leading and
2015 trailing spaces in the bounding box as the other drivers did, it also
2016 produced strange results for empty strings or strings containing only
2017 spaces
2018
2019 - when reading CMYK jpeg images they were being transferred to the
2020 image object as is, producing a four channel image. It only looked ok
2021 due to an old still unfixed Photoshop bug. We now convert from the
2022 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2023 http://rt.cpan.org/Ticket/Display.html?id=20416
2024
2025 - reading a CYMK TIFF would result in a 4 channel image, reading any
2026 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2027 result in an error.
2028 http://rt.cpan.org/Ticket/Display.html?id=20415
2029
2030 - added /usr/local/include to the default include search path, since
2031 we were already searching /usr/local/lib for libraries.
2032
2033And various minor fixes and documentation updates.
2034
2035
2036Imager 0.51 - 23 Apr 2006

2040 a crash
2041 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2042
2043 - fix mis-processing of the src_maxx and src_maxy parameters of the
2044 paste() method

2056 or 4 channel image to jpeg or a 2 channel image to tga where the
2057 output is an in-memeory buffer.
