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

11Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
12================
13
08914ed1
TC
14 - re-work the t/200-file/400-basic.t to correctly handle failures
15 It's custom ok() function didn't have a prototype and didn't use scalar().
16 This caused ok() to use the note instead of the value being tested when
17 the method called returned an empty list. For an example of the problem
e6226ce5 18 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 19
a2791e47
TC
20 - remove some noise from when Imager tried to work with bugs in old
21 versions of giflib. I can't do much about the new bugs.
08914ed1 22
e6226ce5
TC
23 - the new autolevels filter (Imager 0.99) used an integer for the
24 sample scaling factor which caused the top output level to be too
25 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
26 https://rt.cpan.org/Ticket/Display.html?id=111871
27
e6226ce5 28 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
29 minimum and maximum luminance from the histogram. This slightly
30 reduced the contrast of the output image.
31 https://rt.cpan.org/Ticket/Display.html?id=111871
32
33 - the new autolevels filter now uses a lookup table for 8-bit images
34 to avoid a floating point multiply for each sample.
35 https://rt.cpan.org/Ticket/Display.html?id=111871
36
e6226ce5
TC
37 - fixed several memory leaks detected by valgrind:
38
39 - addcolors() leaked the temporary array of colors supplied to the
40 internal API
41
42 - make_palette() leaked the temporary image array (not the images
43 themselves) passed to the internal API.
44
45 - combine()/i_combine() leaked its working row buffers
46
47 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
48 buffer if there were too many colors
49
50 - getcolorcount()/i_count_colors() leaked the sample buffer if
51 there were too many colors.
52
53 - the nearest_color filter (undocumented until I find a use for it)
54 leaked both temporaries passed to the API and internal buffers
55
a2791e47
TC
56 - the internal process of upgrading a paletted image to a direct
57 color image would leak a context object reference count.
58
59 - a write failure when writing to a GIF file could leak memory.
60
61 - failing to write to a 1-bit/pixel ICO image could leak memory.
62
63 - Imager no longer deliberately leaks the context object from the
64 initial thread. This was done to ensure there was always a context
65 object available, but the code that needed that now handles the
66 lack correctly,
67
e6226ce5
TC
68 - fixed some uninitialized memory usage detected by valgrind:
69
70 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
71 i_matrix_transform_bg() didn't initialize a working color value
72 if there was zero pixel coverage.
73
74 - i_ft2_cp() didn't initialize the complete color when producing an
75 intermediate image. This caused uninitialized value usage when
76 logging the color.

TC
94Imager 1.003 - 12 May 2015
95============
96
0fda3cfd
TC
97 - update 1.002 release notes to include the center change for filled
98 circle drawing.
99
100 - flood_fill() would escape beyond a 4-connected space under some
101 circumstances.
102 Added many more flood_fill() tests.

TC
105Imager 1.002 - 3 Apr 2015
106============
107
334b8922
TC
108 - drawing anti-aliased filled circles is now 10 to 50 times faster
109 depending on the size of the circle.
0fda3cfd
TC
110 This also changed the center from being the center of the pixel to
111 being the top left of the pixel to match the filled arcs drawn by
112 arc().

TC
113 https://rt.cpan.org/Ticket/Display.html?id=101682
114
115 - enhancements to polygon filling:
116
117 - added a mode parameter to control how overlapping regions behave
118
119 - added a polypolygon() method to fill more than one polygon at a
120 time
121
122 - polygon filling is now exposed through the API.
123
45c8e262
TC
124 - added colormodel(), alphachannel() and colorchannels() methods.
125 These were added for two reasons:
126
127 - a future version of Imager may allow the number of channels in
128 an image to not directly represent the color model of an image.
129 eg. a greyscale TIFF image with multiple alpha channels.
130
131 - a future version of Imager may allow an image to be read without
132 translation, for example a TIFF file that contains measurements
0fda3cfd 133 from an instrument. Currently Imager transforms the samples into
45c8e262
TC
134 the range 0.0 ... 1.0 which may means the user has to translates
135 the value back.
136
137 An untranslated image would be unusable as image data, so
138 colormodel() would return "unknown" in this case.
139
140 Similarly a CMYK image might be returned as an "unknown" color
141 model image, if the caller chooses to disable translation to
142 RGB.

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

172Imager 1.000 - 28 Jul 2014
173============
174
175There's nothing special about Imager 1.000, it's just another release.
176
fa3dac1d
TC
177 - fix the skip check for the iolayer qr// buffer test
178
179 - improve error reporting for the iolayer test failing on a small
180 number of Win32 CPAN testers

TC
182Imager 0.99_02 - 21 Jul 2014
183==============
184
5dab5b9a
TC
185 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
186 the blue channel in the generated palette, and allow each color
187 component to be in the range 100..255 instead of just 100..254.
188 Thanks to Ralf Neubauer.
189 https://rt.cpan.org/Ticket/Display.html?id=97086
190
191 - revert "improved the XS for i_io_read() and i_io_raw_read()"
192 This caused problems with older perls and didn't provide much of a
193 performance improvement.
194
5bf25bc2 195 - support Inline 0.57 and later.
6d47a6af 196 Inline 0.57 changed the "with" interface.

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

203Imager 0.99_01 - 29 Jun 2014
204==============
205
7b486870
TC
206 - GIF: add support for giflib 5.1.0, which added error code pointer
207 parameters to EGifCloseFile() and DGifCloseFile().
208 https://rt.cpan.org/Ticket/Display.html?id=96756
209
210 - GIF: avoid a double-free when do_write() fails.
211
28104a85 212 - fix SV type probing to work on perl before 5.12. Broken in 0.99.

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

219Imager 0.99 - 25 Jun 2014
220===========
221
dce1523b
TC
222 - Imager::IO->new_buffer() (and hence Imager->read()'s data
223 parameter) now accepts a reference to a scalar as well as just a
224 plain scalar.
6a160bce 225 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
226
227 - Imager::IO->new_buffer() now always makes a copy of the passed in
228 buffer to avoid problems with temporary objects used for the return
229 value of SvPVbyte().
6a160bce 230 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 231
c757e211
TC
232 - improved the XS for i_io_read() and i_io_raw_read()
233 https://rt.cpan.org/Ticket/Display.html?id=92738
234
235 - load plugins from absolute paths on Android
236 Thanks to Brian Fraser.
237 https://rt.cpan.org/Ticket/Display.html?id=93272
238
6a160bce
TC
239 - added the jpeg_optimize parameter for writing JPEG files. This can
240 significantly reduce file sizes, but uses more memory and time.
241 https://rt.cpan.org/Ticket/Display.html?id=94292
242
14fd9e5d
TC
243 - the autolevels filter now works on the luminosity of the image
244 rather then working per channel. The old autolevels filter is
245 still available as "autolevels_skew".
246 https://rt.cpan.org/Ticket/Display.html?id=94413
247
75d54149
TC
248 - Imager::File::PNG now supports libpng 1.6.10.
249 1.6.10 changed CRC errors from benign errors to normal errors,
250 which broke the test which used CRC errors to check for benign
251 error support. Switched to using a 1-bit grey-scale image with a
252 palette to test for benign errors.
253 https://rt.cpan.org/Ticket/Display.html?id=94717

TC
255Imager 0.98 - 3 Jan 2014
256===========
257
f84f86a2
TC
258Incompatible changes:
259
260 - the return value of setpixel() has changed.
261
262 Previously the return values for undrawable pixels vs caller errors
263 changed depending on whether you used the multiple pixel calling
264 mechanism, or the single pixel mechanism.
265
266 Now:
267
268 - for an invalid parameter, such as an unknown colour, or missing
269 parameter, an empty list (or undef in scalar context) is
270 returned, and errstr() is set,
271
272 - otherwise the number of pixels drawn is returned. If none of
273 the pixels could be drawn (they were all outside the image), "0
274 but true" is returned.
275
276 https://rt.cpan.org/Ticket/Display.html?id=87650
277
278Other changes:
279
6ba09ab9
TC
280 - when drawing on an image with an alpha channel where the source
281 minimum is greater than zero, Imager would read from beyond the end
282 of a malloc() allocated buffer. In rare circumstances this could
283 lead to some of the source image not being written to the target
284 image, or possibly to a segmentation fault.
285 I don't believe this has any security concerns beyond that.
286
0d052fd9
TC
287 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
288 text drawn would be nonsense. This would also read beyond the end
289 of a malloced buffer.
290
13671b17
TC
291 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
292 truncated early.
293 https://rt.cpan.org/Ticket/Display.html?id=88993
294
d6f4e964
TC
295 - Imager::Font::Wrap no longer requires the image parameter.
296 https://rt.cpan.org/Ticket/Display.html?id=87338
297
f84f86a2
TC
298 - a documentation typo fix in Imager::Transformations
299 Thanks to Adrian Yee.
300 https://rt.cpan.org/Ticket/Display.html?id=88598
301
0179ecd6
TC
302 - Image::Probe, Imager's internal module for probing library
303 locations now searches the directories specified by LD_RUN_PATH,
304 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
305 and the corresponing s/\blib$/include/ directories for header
306 files.

TC
317 - PNG: treat a version mismatch between headers and library as a
318 probe failure.
319 https://rt.cpan.org/Ticket/Display.html?id=86659
320
8e90f677
TC
321 - PNG: the check for benign error support is more complex than a
322 simple library version check, check for the appropriate macro.
323 Thanks for Slaven Rezic for following up on my CPAN Testers result
324 queries.

TC
331==============
332
05c9b356
TC
333 - TIFF: handle SampleFormat = 2 by translating the signed integer
334 values to unsigned by flipping their sign bits.
335
336 Handle SampleFormat = 3 where possible.
337
338 SampleFormat is ignored for paletted images.
339
237d9e03
TC
340 Mixed SampleFormat are handled incorrectly, since libtiff returns
341 only the first SampleFormat value, and an image with both an alpha
342 channel and SampleFormat = 2 for color channels probably has a
343 different SampleFormat for the alpha channel.

face45e7 349
237d9e03 350 - Imager::Color's rgba() method now returns its values as integers
face45e7
TC
351 instead of floating point. (IV instead of NV).
352
19e9591b
TC
353 - The XS for i_map() and i_matrix_transform() now use the AV *
354 typemap instead of rolling their own.
355
75cebca8
TC
356 - The XS for DSO_call() now uses the HV * typemap instead of
357 rolling it's own.
358
0aaa8b4d
TC
359 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
360 i_gradgen() now use a new T_AVARRAY typemap that greatly
361 simplifies the XS code.
face45e7 362
ccd01d49
TC
363 - many other minor XS changes
364
face45e7 365 - some XS code formatting
a54e32ba 366
dcab59bc
TC
367 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
368 now renders in alpha-combining mode, to match antialiased output.

TC
387 - rearrange Imager's test files.
388 https://rt.cpan.org/Ticket/Display.html?id=84596
389
390 - Imager::Probe::_gcc_lib_paths now forces C locale.
391 A sufficiently recent gcc prints localized keys for the search
392 paths, which avoids that localization.
393 https://rt.cpan.org/Ticket/Display.html?id=84963
394
395 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
396 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
397 and true.
398 https://rt.cpan.org/Ticket/Display.html?id=85262

414Imager 0.95 - 19 Apr 2013
415===========
416
0a2956ab
TC
417 - handle the SVf_UTF8 flag correctly on magic strings passed to
418 Imager::IO's write() and raw_write() methods.
419 This may misbehave in perl 5.6.x since the UTF8 flag may not be
420 visible in the main SV after SvGETMAGIC().
421 https://rt.cpan.org/Ticket/Display.html?id=83438
422
423 - document that bounding_box() ignores the transformation matrix
424 supplied to tranform() for fonts.

TC
430 - enable debug logging for the standard font tests
431
432 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
433 due to a bug in that version of perl.
434
435 - don't test for read() failing on a write-only handle in 5.8.x and
436 earlier, this was fixed in change 862083f7e4 in perl.
437
438 - report the version of Inline found during testing (an attempt to
439 diagnose some intermittent failures.)

14a4ea18 444 - NOTE: possibly backward incompatible:
3dcf7595
TC
445 support reading from/writing to perl filehandes that aren't raw
446 files.
447
448 This allows Imager's I/O to honour handles with layers such as
449 gzip, scalar file handles or tied file handles.
450
14a4ea18 451 This is backward incompatible in that previous Imager would simply

553
554 - support for giflib 5.0. (5.0.1 and later)
555 https://rt.cpan.org/Ticket/Display.html?id=79029
556 The giflib API Imager uses doesn't have a mechanism to set the
557 header version in 5.0.0.
558
559 - update the GIF library probe code to check for the new giflib 5.0.1
560 EGifSetGifVersion() function, and to check for the giflib 4.2.0
561 uninitialized gif89 bug.

565 - avoid static variables when capturing IPTC data from JPEG files
566
567 - match Imager::Font;:T1's error message translations to those from
568 later versions of T1Lib.
569
570 - for libtiff versions that support extended warning handlers (3.8.0
571 or later), use them to avoid some global variables.

TC
592 - The size of rotated images is no longer rounded up so aggressively.
593 Added rounding to the linear interpolation done for rotate() and
594 matrix_transform() for 1 and 3 channel 8-bit images.
595 Adjusted the two tranlate matrices used to build the final rotation
596 matrix to use the distance between the outlier pixels rather than
597 the pixel dimensions (ie. dimension-1).
598 With all of this the output of rotate(degrees => 270) on an 8-bit
599 image exactly matches the output of rotate(right => 270).
600 https://rt.cpan.org/Ticket/Display.html?id=77063
601
ef84bb32
TC
602Other changes:
603
604 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
605 internals, those names only matter for the XS interface.
606
607 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
608 the API level compiled into a loadable module such as
609 Imager::File::GIF doesn't match that of Imager. Previously it
610 could be difficult to determine exactly which module was failing to
611 load.
612 https://rt.cpan.org/Ticket/Display.html?id=77173
613
614 - added Imager->check_file_limits() as an interface to the
615 i_int_check_image_file_limits() API.
616
617 - Imager->set_file_limits(reset => 1) now resets the limits to the
618 defaults rather than setting them all to unlimited.

624===========
625
626Bug fixes:

629 parameter but the prototype didn't allow for the extra parameter.
630 Corrected the prototype.
631
29b38678
TC
632 - when downconverting samples (eg. from floating point to 8 bit)
633 Imager now rounds the sample value rather than attempting to
634 allocate input values over output values equally. The old
635 behaviour had the probably surprising effect of converting a
636 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
637 2.
638 This may result in slightly different 8 or 16-bit output images.
639
e2a86bac
TC
640 - BI_BITFIELD BMP images were handled incorrectly, both in
641 incorrectly calculating the space required for the masks and in
642 processing the image data itself.
643 https://rt.cpan.org/Ticket/Display.html?id=76736
644
645 - some odd width BMP BI_RLE4 images use run lengths that run one off
646 the edge of the image. Imager now allows this, discarding the
647 extra column.
648
649 - odd length RLE4 runs in BMP images were decoded incorrectly.
650
82eb0687
TC
651 - pkg-config could sometimes return a library that was in a directory
652 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
653 If no -L is included in the pkg-config library information check if
654 EU::MM can find the library, and if not, search our configured
655 directories and insert that into the library flags.
656 https://rt.cpan.org/Ticket/Display.html?id=75869

TC
658 - Imager::Probe can now probe for libraries with dependent libraries,
659 common for static linking, eg. libpng requires libz.
660 https://rt.cpan.org/Ticket/Display.html?id=74043
661
662 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
663
664 - added alternative probe configurations that try to link libz, to
665 handle a statically linked libpng.
666 https://rt.cpan.org/Ticket/Display.html?id=74043
667
668 - if a probe includes testcode, Imager::Probe now checks that code as
669 part of the process of checking each configuration rather than as a
670 post test of the found configuration. This allows alternate
671 configurations to be checked if a matching but non-working
672 configuration is found.

748 - setsamples() is now a true complement to getsamples() - it can
749 write 8-bit or floating point samples from a scalar or array
750 reference. This adds i_psamp() and i_psampf() to the C level API.
751
752 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
753 changed to make better use of the typemap, but these aren't part of
754 the perl level API anyway. There were no changes to the C level

907
908 - add simple tests for the Imager::Test test_image generators

TC
910 - io_glue I/O buffering re-work:
911
912 - reorganize io_glue to do it's own buffering by default
913
914 - the unbuffered functions are available as i_io_raw_read() (or
915 raw_read() from perl) etc but are not recommended for typical
916 use.
917
918 - use the new i_io_peekn() when checking for file magic to avoid
919 seek, allowing Imager to detect the file type and read the file
920 from an unseekable stream (for formats that don't use random
921 access)
922
923 - added several new I/O layer API functions.
924
925 - fix the TGA performance problem, most noticably on Win32
926 https://rt.cpan.org/Ticket/Display.html?id=70037
927
928 - TIFF now uses wrapper functions of the correct types to avoid casts
929 https://rt.cpan.org/Ticket/Display.html?id=69912
930
931 - the callback IO object did its own buffering, controlled by the
932 maxbuffer parameter supplied to the read() and write() methods.
933 This buffering has been removed, to avoid redundancy with the
934 common io_glue buffering. This also avoids a bug in that code
935 which could rarely pass a zero length to the read callback and
936 then panic about the result.
937
938 - the callback IO object now tests the result of calling the close
939 callback, which should return true for success.
940
941 - the PNM reader did its own buffering. This buffering has been
942 removed to avoid redundancy with the common io_glue buffering.
943
944 - previously the read handlers for fd and callback I/O layers would
945 call the underlying interface (POSIX read or your supplied callback)
946 until it filled the buffer. It now only makes one call.
947
948 - added public constructors for I/O layer objects (see Imager::IO)
949
950 - all core file handlers now use the i_io_foo() wrappers to gain
951 access to buffered I/O rather than calling the I/O layer
952 callbacks directly.
953
954 - all core file handlers now check for error on close.
955
956 - Backward compatibility: if you hava custom file handlers, you can
957 use i_io_write() etc since they're available as macros in older
958 versions of Imager.
959
960 - eliminate the final remnants of io_glue_commit_types().
961
962 - bump IMAGER_API_VERSION, since the above may break assumptions.
963
964 - removed the long unused i_gen_reader() and i_gen_writer() utility
965 functions.

1027
1028Development release as a sanity check for the types re-work.
8d14daab
TC
1029
1030Massive types re-work:
1031
1032 - the type used internally for pixel co-ordinates and image sizes is
1033 now 64-bit on 64-bit platforms (at least sane ones).
1034
1035 - size_t is now used consistently for memory block sizes.
1036
1037 - since this changes the binary interface, the Imager API version has
1038 been incremented. Any module that uses the API will need to be
1039 rebuilt. In most cases that will be enough, but calls to any APIs
1040 that take a pointer to image sizes may need source changes.
1041
1042 - you should be able to create very large images on 64-bit systems,
1043 if you have enough memory. Successfully created a 32768 x 49192 x
1044 3 channel image, filled with a tiled image and scaled it. The
1045 unscaled image was also successfully saved to a JPEG.
1046
1047 - check the image size before attempting to write BMP, GIF, JPEG,
1048 PNG, SGI, TGA, TIFF images.
1049
1050 - correctly handle reading TGA images over 32767 pixels wide or tall.
1051
1052Incidental changes:
1053
1054 - the gif_left and gif_top tags are now clamped to non-negative
1055 values when writing a GIF image.
1056
1057 - removed dead callback read/write code
1058
1059The default maximum memory size when reading files is now 1G.

1762 - some TGA images weren't being detected correctly as TGA images
1763 https://rt.cpan.org/Ticket/Display.html?id=32925
1764
1765 - handling of the left-over bit for 16-bit/pixel TGA images has been
1766 changed to match the behaviour of the GIMP. Previously the bit
1767 being set was treated as an opaque pixel, but one user reported a
1768 problem with loading such an image. I haven't been able to find any
1769 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1770 I'll match it's behaviour. See issue 114913 in the GIMP's
1771 bugzilla.

1781 - the old dynaload code used Mach API functions to load dynamic
1782 libraries on Mac OS X. These APIs have been deprecated in OS X
1783 10.5 and were causing some build problems.
1784 So henceforth Imager uses the dlopen() family of functions, and you
1785 will need version 10.3 or later of OS X.

2094Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2095
2096There is one new feature:

2100 http://rt.cpan.org/Ticket/Display.html?id=22166

2104 - the string() method would not output the string "0"
2105 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2106
2107 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2108 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2109
2110 - the gif_disposal and gif_user_input tags weren't being read from
2111 the file correctly
2112 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2113
2114 - gif.c was failing to build under MSVC
2115 http://rt.cpan.org/Ticket/Display.html?id=23922
2116
2117 - in some cases strings passed to the string() method were treated as
2118 terminated by NUL (chr 0)
2119 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2120
2121 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2122 that's the default build name for zlib on Win32.
2123 http://rt.cpan.org/Ticket/Display.html?id=23064
2124
2125 - search $Config{incpath} for headers too, which we should have been
2126 doing all along.
2127
2128Win32 font driver fixes:
2129
2130 - the global descent value from bounding box was the wrong sign
2131 http://www.cpanforum.com/threads/3276

2136
2137Imager 0.54 - 14 Sep 2006
2138===========
2139
2140This is primarily a feature release:
2141
2142 - a new qtype value 'mixing' has been added to the scale()
2143 method. This is faster than 'normal', slower than 'preview'. This
2144 is based on the method used by pnmscale, and seems to produce less
2145 blurry results than normal.
2146 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2147
2148 - the rubthrough() method can now render onto images with an alpha
2149 channel.
2150 http://rt.cpan.org/Ticket/Display.html?id=20678
2151
2152 - the read_multi() method now falls back to calling doing a single
2153 image read via the read() method and write_multi() will now fall
2154 back to calling write() if a single image is supplied. This means
2155 you can simply call the read_multi() or write_multi() functions
2156 without having to check if the type is formatted by that method.
2157 http://rt.cpan.org/Ticket/Display.html?id=19457
2158 http://rt.cpan.org/Ticket/Display.html?id=19458
2159
2160 - the GIF loop extension can now be written. If you don't have
2161 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2162 should upgrade.
2163 http://rt.cpan.org/Ticket/Display.html?id=21185
2164
2165 - getscanline() and setscanline() can now read/write palette index
2166 based data from/to the image for paletted images, by setting type to
2167 'index'.
2168 http://rt.cpan.org/Ticket/Display.html?id=20338
2169
2170 - we no longer hassle you to disable GIF support
2171 http://rt.cpan.org/Ticket/Display.html?id=20687
2172
2173 - minor documentation fixes
2174

2176Imager 0.53 - 26 Jul 2006
2177===========
2178
2179This is a bugfix release.

2187Imager 0.52 - 25 Jul 2006
2188===========
2189
2190This is primarily a feature release, but contains a fair few bug
2191fixes, new features:
2192
2193 - ability to read and write MS Windows ICO and CUR files
2194
2195 - you can now add file format plugins to support new file formats
2196
2197 - add POD coverage tests
2198
2199 - setcolors() and addcolors() now accept color names and so on
2200 instead of requiring Imager::Color objects.
2201 http://rt.cpan.org/Ticket/Display.html?id=20056
2202
2203 - flood_fill() can now fill to a specified border color instead of
2204 just to the area the same color as the seed.
2205 http://rt.cpan.org/Ticket/Display.html?id=19618
2206
2207
2208Bug fixes:
2209
2210 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2211 calculating the advance width.
2212 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2213
2214 - bounding_box for the T1 driver wasn't including leading and
2215 trailing spaces in the bounding box as the other drivers did, it also
2216 produced strange results for empty strings or strings containing only
2217 spaces
2218
2219 - when reading CMYK jpeg images they were being transferred to the
2220 image object as is, producing a four channel image. It only looked ok
2221 due to an old still unfixed Photoshop bug. We now convert from the
2222 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2223 http://rt.cpan.org/Ticket/Display.html?id=20416
2224
2225 - reading a CYMK TIFF would result in a 4 channel image, reading any
2226 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2227 result in an error.
2228 http://rt.cpan.org/Ticket/Display.html?id=20415
2229
2230 - added /usr/local/include to the default include search path, since
2231 we were already searching /usr/local/lib for libraries.
2232
2233And various minor fixes and documentation updates.
