4============

6It's now been ten years since I switched to the new Changes file in
7release 0.55.
8
cd0109d8
TC
9 - revert the ivdformat probes, they don't work as is and trying to
10 fix them is too much work for now.

TC
12Imager 1.004_004 - 15 Apr 2016
13================
14
9c45cc49
TC
15 - test that the ivdformat from Config is correct and look for a valid
16 one if it isn't.
17 For the strange Win32 failures.
18
19 - fix a copy and paste error in pod in samples/samp-form.cgi

21Imager 1.004_003 - 23 Mar 2016
22================
23
bd2d657d
TC
24 - add some extra error reporting to the I/O layers tests, this might
25 help catch a failure seen on Win32.

28Imager 1.004_002 - 20 Mar 2016
29================
30
735b3e7b
TC
31 - don't use the seek() method on opened() handles in
32 t/200-file/400-basic.t. In older versions of perl such handles are
33 only IO::Handle objects, not IO::File, and don't have a seek()
34 method.

36Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
37================
38
08914ed1
TC
39 - re-work the t/200-file/400-basic.t to correctly handle failures
40 It's custom ok() function didn't have a prototype and didn't use scalar().
41 This caused ok() to use the note instead of the value being tested when
42 the method called returned an empty list. For an example of the problem
e6226ce5 43 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 44
a2791e47
TC
45 - remove some noise from when Imager tried to work with bugs in old
46 versions of giflib. I can't do much about the new bugs.
08914ed1 47
e6226ce5
TC
48 - the new autolevels filter (Imager 0.99) used an integer for the
49 sample scaling factor which caused the top output level to be too
50 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
51 https://rt.cpan.org/Ticket/Display.html?id=111871
52
e6226ce5 53 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
54 minimum and maximum luminance from the histogram. This slightly
55 reduced the contrast of the output image.
56 https://rt.cpan.org/Ticket/Display.html?id=111871
57
58 - the new autolevels filter now uses a lookup table for 8-bit images
59 to avoid a floating point multiply for each sample.
60 https://rt.cpan.org/Ticket/Display.html?id=111871
61
e6226ce5
TC
62 - fixed several memory leaks detected by valgrind:
63
64 - addcolors() leaked the temporary array of colors supplied to the
65 internal API
66
67 - make_palette() leaked the temporary image array (not the images
68 themselves) passed to the internal API.
69
70 - combine()/i_combine() leaked its working row buffers
71
72 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
73 buffer if there were too many colors
74
75 - getcolorcount()/i_count_colors() leaked the sample buffer if
76 there were too many colors.
77
78 - the nearest_color filter (undocumented until I find a use for it)
79 leaked both temporaries passed to the API and internal buffers
80
a2791e47
TC
81 - the internal process of upgrading a paletted image to a direct
82 color image would leak a context object reference count.
83
84 - a write failure when writing to a GIF file could leak memory.
85
86 - failing to write to a 1-bit/pixel ICO image could leak memory.
87
88 - Imager no longer deliberately leaks the context object from the
89 initial thread. This was done to ensure there was always a context
90 object available, but the code that needed that now handles the
91 lack correctly,
92
e6226ce5
TC
93 - fixed some uninitialized memory usage detected by valgrind:
94
95 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
96 i_matrix_transform_bg() didn't initialize a working color value
97 if there was zero pixel coverage.
98
99 - i_ft2_cp() didn't initialize the complete color when producing an
100 intermediate image. This caused uninitialized value usage when
101 logging the color.

103Imager 1.004 - 8 Nov 2015
104============
105
5ebfb369
TC
106 - Imager::Color::Table is now pre-loaded by the preload() method.
107 https://rt.cpan.org/Ticket/Display.html?id=104896
108
109 - fix an assertion triggered under perl 5.23.4.
110 Thanks to A. Sinan Unur for the report and the patch.
111
7b638aba
TC
112 - Imager->new can now be used to read raw image files.
113 https://rt.cpan.org/Ticket/Display.html?id=106836
f7160b21 114 Thanks to Richard Kelsch for reporting this.
7b638aba
TC
115
116 - deal with output changes from Pod::Spell

TC
119Imager 1.003 - 12 May 2015
120============
121
0fda3cfd
TC
122 - update 1.002 release notes to include the center change for filled
123 circle drawing.
124
125 - flood_fill() would escape beyond a 4-connected space under some
126 circumstances.
127 Added many more flood_fill() tests.

TC
130Imager 1.002 - 3 Apr 2015
131============
132
334b8922
TC
133 - drawing anti-aliased filled circles is now 10 to 50 times faster
134 depending on the size of the circle.
0fda3cfd
TC
135 This also changed the center from being the center of the pixel to
136 being the top left of the pixel to match the filled arcs drawn by
137 arc().
334b8922
TC
138 https://rt.cpan.org/Ticket/Display.html?id=101682
139
140 - enhancements to polygon filling:
141
142 - added a mode parameter to control how overlapping regions behave
143
144 - added a polypolygon() method to fill more than one polygon at a
145 time
146
147 - polygon filling is now exposed through the API.
148
45c8e262
TC
149 - added colormodel(), alphachannel() and colorchannels() methods.
150 These were added for two reasons:
151
152 - a future version of Imager may allow the number of channels in
153 an image to not directly represent the color model of an image.
154 eg. a greyscale TIFF image with multiple alpha channels.
155
156 - a future version of Imager may allow an image to be read without
157 translation, for example a TIFF file that contains measurements
0fda3cfd 158 from an instrument. Currently Imager transforms the samples into
45c8e262
TC
159 the range 0.0 ... 1.0 which may means the user has to translates
160 the value back.
161
162 An untranslated image would be unusable as image data, so
163 colormodel() would return "unknown" in this case.
164
165 Similarly a CMYK image might be returned as an "unknown" color
166 model image, if the caller chooses to disable translation to
167 RGB.

TC
169Imager 1.001 - 2 Jan 2015
170============
171
aca60e01
TC
172 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
173 Thanks to Slaven Rezic for the report and the patch.
174 https://rt.cpan.org/Public/Bug/Display.html?id=98234
175
0df260f6
TC
176 - GIF: clean-up a test file if the test for the giflib 4.2.0 file
177 version bug fails.
178
179 - fix Imager::Matrix2d::rotate()'s centre point handling
180 https://rt.cpan.org/Public/Bug/Display.html?id=99959
181
182 - ICO: don't apply the icon mask to images with an alpha channel by
183 default
184 https://rt.cpan.org/Public/Bug/Display.html?id=99507
185
56605f3f
TC
186 - make verbose probing output more verbose

f74bd978
TC
188 - use Imager::Probe to probe for freetype 1.x
189 https://rt.cpan.org/Ticket/Display.html?id=100502
190
191 - The --enable and --disable parameters to the top-level Makefile.PL
192 work again.
193
c7f06039

197Imager 1.000 - 28 Jul 2014
198============
199
200There's nothing special about Imager 1.000, it's just another release.
201
fa3dac1d
TC
202 - fix the skip check for the iolayer qr// buffer test
203
204 - improve error reporting for the iolayer test failing on a small
205 number of Win32 CPAN testers
206

TC
207Imager 0.99_02 - 21 Jul 2014
208==============
209
5dab5b9a
TC
210 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
211 the blue channel in the generated palette, and allow each color
212 component to be in the range 100..255 instead of just 100..254.
213 Thanks to Ralf Neubauer.
214 https://rt.cpan.org/Ticket/Display.html?id=97086
215
216 - revert "improved the XS for i_io_read() and i_io_raw_read()"
217 This caused problems with older perls and didn't provide much of a
218 performance improvement.
219
5bf25bc2 220 - support Inline 0.57 and later.
6d47a6af 221 Inline 0.57 changed the "with" interface.
5bf25bc2
TC
222 https://rt.cpan.org/Ticket/Display.html?id=97108
223
6d47a6af
TC
224 - don't define our own MAXINT macro, it conflicts with windows header
225 files and in a few places it was the wrong value to use anyway.

228Imager 0.99_01 - 29 Jun 2014
229==============
230
7b486870
TC
231 - GIF: add support for giflib 5.1.0, which added error code pointer
232 parameters to EGifCloseFile() and DGifCloseFile().
233 https://rt.cpan.org/Ticket/Display.html?id=96756
234
235 - GIF: avoid a double-free when do_write() fails.
236
28104a85 237 - fix SV type probing to work on perl before 5.12. Broken in 0.99.
ea87cee9
TC
238 https://rt.cpan.org/Ticket/Display.html?id=96761
239
df04d4b3
TC
240 - PNG: skip the benign error test before libpng 1.6.0, since the
241 error we're testing didn't exist before 1.6.0.
242 https://rt.cpan.org/Ticket/Display.html?id=94717 (continued)

TC
244Imager 0.99 - 25 Jun 2014
245===========
246
dce1523b
TC
247 - Imager::IO->new_buffer() (and hence Imager->read()'s data
248 parameter) now accepts a reference to a scalar as well as just a
249 plain scalar.
6a160bce 250 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
251
252 - Imager::IO->new_buffer() now always makes a copy of the passed in
253 buffer to avoid problems with temporary objects used for the return
254 value of SvPVbyte().
6a160bce 255 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 256
c757e211
TC
257 - improved the XS for i_io_read() and i_io_raw_read()
258 https://rt.cpan.org/Ticket/Display.html?id=92738
259
260 - load plugins from absolute paths on Android
261 Thanks to Brian Fraser.
262 https://rt.cpan.org/Ticket/Display.html?id=93272
263
6a160bce
TC
264 - added the jpeg_optimize parameter for writing JPEG files. This can
265 significantly reduce file sizes, but uses more memory and time.
266 https://rt.cpan.org/Ticket/Display.html?id=94292
267
14fd9e5d
TC
268 - the autolevels filter now works on the luminosity of the image
269 rather then working per channel. The old autolevels filter is
270 still available as "autolevels_skew".
271 https://rt.cpan.org/Ticket/Display.html?id=94413
272
75d54149
TC
273 - Imager::File::PNG now supports libpng 1.6.10.
274 1.6.10 changed CRC errors from benign errors to normal errors,
275 which broke the test which used CRC errors to check for benign
276 error support. Switched to using a 1-bit grey-scale image with a
277 palette to test for benign errors.
278 https://rt.cpan.org/Ticket/Display.html?id=94717

TC
280Imager 0.98 - 3 Jan 2014
281===========
282
f84f86a2
TC
283Incompatible changes:
284
285 - the return value of setpixel() has changed.
286
287 Previously the return values for undrawable pixels vs caller errors
288 changed depending on whether you used the multiple pixel calling
289 mechanism, or the single pixel mechanism.
290
291 Now:
292
293 - for an invalid parameter, such as an unknown colour, or missing
294 parameter, an empty list (or undef in scalar context) is
295 returned, and errstr() is set,
296
297 - otherwise the number of pixels drawn is returned. If none of
298 the pixels could be drawn (they were all outside the image), "0
299 but true" is returned.
300
301 https://rt.cpan.org/Ticket/Display.html?id=87650
302
303Other changes:
304
6ba09ab9
TC
305 - when drawing on an image with an alpha channel where the source
306 minimum is greater than zero, Imager would read from beyond the end
307 of a malloc() allocated buffer. In rare circumstances this could
308 lead to some of the source image not being written to the target
309 image, or possibly to a segmentation fault.
310 I don't believe this has any security concerns beyond that.
311
0d052fd9
TC
312 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
313 text drawn would be nonsense. This would also read beyond the end
314 of a malloced buffer.
315
13671b17
TC
316 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
317 truncated early.
318 https://rt.cpan.org/Ticket/Display.html?id=88993
319
d6f4e964
TC
320 - Imager::Font::Wrap no longer requires the image parameter.
321 https://rt.cpan.org/Ticket/Display.html?id=87338
322
f84f86a2
TC
323 - a documentation typo fix in Imager::Transformations
324 Thanks to Adrian Yee.
325 https://rt.cpan.org/Ticket/Display.html?id=88598
326
0179ecd6
TC
327 - Image::Probe, Imager's internal module for probing library
328 locations now searches the directories specified by LD_RUN_PATH,
329 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
330 and the corresponing s/\blib$/include/ directories for header
331 files.

TC
339Imager 0.96_02 - 8 Jul 2013
340==============
341
aaf82685
TC
342 - PNG: treat a version mismatch between headers and library as a
343 probe failure.
344 https://rt.cpan.org/Ticket/Display.html?id=86659
345
8e90f677
TC
346 - PNG: the check for benign error support is more complex than a
347 simple library version check, check for the appropriate macro.
348 Thanks for Slaven Rezic for following up on my CPAN Testers result
349 queries.
350 https://rt.cpan.org/Ticket/Display.html?id=86659

TC
356==============
357
05c9b356
TC
358 - TIFF: handle SampleFormat = 2 by translating the signed integer
359 values to unsigned by flipping their sign bits.
360
361 Handle SampleFormat = 3 where possible.
362
363 SampleFormat is ignored for paletted images.
364
237d9e03
TC
365 Mixed SampleFormat are handled incorrectly, since libtiff returns
366 only the first SampleFormat value, and an image with both an alpha
367 channel and SampleFormat = 2 for color channels probably has a
368 different SampleFormat for the alpha channel.

face45e7 372 - XS clean up:
29969fa2 373 https://rt.cpan.org/Ticket/Display.html?id=69243
face45e7 374
237d9e03 375 - Imager::Color's rgba() method now returns its values as integers
face45e7
TC
376 instead of floating point. (IV instead of NV).
377
19e9591b
TC
378 - The XS for i_map() and i_matrix_transform() now use the AV *
379 typemap instead of rolling their own.
380
75cebca8
TC
381 - The XS for DSO_call() now uses the HV * typemap instead of
382 rolling it's own.
383
0aaa8b4d
TC
384 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
385 i_gradgen() now use a new T_AVARRAY typemap that greatly
386 simplifies the XS code.
face45e7 387
ccd01d49
TC
388 - many other minor XS changes
389
face45e7 390 - some XS code formatting
a54e32ba 391
dcab59bc
TC
392 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
393 now renders in alpha-combining mode, to match antialiased output.
394 https://rt.cpan.org/Ticket/Display.html?id=73359
b482243a 395
8db7b6fa
TC
396 - add sample code and cookbook notes for drawing a blurred drop-shadow.
397
398 - add support for libpng 1.6, which changed the defaults for
399 reporting some types of error.

TC
402 - FT2: use gsamp/psamp() to transfer pixels from the work image to
403 the output image instead of gpix/ppix.
404 https://rt.cpan.org/Ticket/Display.html?id=83478

409Imager 0.96 - 19 May 2013
410===========
411
c2e251d9
TC
412 - rearrange Imager's test files.
413 https://rt.cpan.org/Ticket/Display.html?id=84596
414
415 - Imager::Probe::_gcc_lib_paths now forces C locale.
416 A sufficiently recent gcc prints localized keys for the search
417 paths, which avoids that localization.
418 https://rt.cpan.org/Ticket/Display.html?id=84963
419
420 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
421 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
422 and true.
423 https://rt.cpan.org/Ticket/Display.html?id=85262
424 reported by Andreas König
425
426 - add a test for unclosed POD in C source, and fix the errors it
427 found.
428 https://rt.cpan.org/Ticket/Display.html?id=74875
429
430 - fix some spelling errors detected by the newer aspell in Debian
431 Wheezy.
432
433 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
434 thanks to gregor herrmann <gregoa@debian.org>
435 https://rt.cpan.org/Ticket/Display.html?id=85413

TC
439Imager 0.95 - 19 Apr 2013
440===========
441
0a2956ab
TC
442 - handle the SVf_UTF8 flag correctly on magic strings passed to
443 Imager::IO's write() and raw_write() methods.
444 This may misbehave in perl 5.6.x since the UTF8 flag may not be
445 visible in the main SV after SvGETMAGIC().
446 https://rt.cpan.org/Ticket/Display.html?id=83438
447
448 - document that bounding_box() ignores the transformation matrix
449 supplied to tranform() for fonts.

578
579 - support for giflib 5.0. (5.0.1 and later)
580 https://rt.cpan.org/Ticket/Display.html?id=79029
581 The giflib API Imager uses doesn't have a mechanism to set the
582 header version in 5.0.0.
583
584 - update the GIF library probe code to check for the new giflib 5.0.1
585 EGifSetGifVersion() function, and to check for the giflib 4.2.0
586 uninitialized gif89 bug.

590 - avoid static variables when capturing IPTC data from JPEG files
591
592 - match Imager::Font;:T1's error message translations to those from
593 later versions of T1Lib.
594
595 - for libtiff versions that support extended warning handlers (3.8.0
596 or later), use them to avoid some global variables.

TC
617 - The size of rotated images is no longer rounded up so aggressively.
618 Added rounding to the linear interpolation done for rotate() and
619 matrix_transform() for 1 and 3 channel 8-bit images.
620 Adjusted the two tranlate matrices used to build the final rotation
621 matrix to use the distance between the outlier pixels rather than
622 the pixel dimensions (ie. dimension-1).
623 With all of this the output of rotate(degrees => 270) on an 8-bit
624 image exactly matches the output of rotate(right => 270).
625 https://rt.cpan.org/Ticket/Display.html?id=77063
626
ef84bb32
TC
627Other changes:
628
629 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
630 internals, those names only matter for the XS interface.
631
632 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
633 the API level compiled into a loadable module such as
634 Imager::File::GIF doesn't match that of Imager. Previously it
635 could be difficult to determine exactly which module was failing to
636 load.
637 https://rt.cpan.org/Ticket/Display.html?id=77173
638
639 - added Imager->check_file_limits() as an interface to the
640 i_int_check_image_file_limits() API.
641
642 - Imager->set_file_limits(reset => 1) now resets the limits to the
643 defaults rather than setting them all to unlimited.

651Bug fixes:

654 parameter but the prototype didn't allow for the extra parameter.
655 Corrected the prototype.
656
29b38678
TC
657 - when downconverting samples (eg. from floating point to 8 bit)
658 Imager now rounds the sample value rather than attempting to
659 allocate input values over output values equally. The old
660 behaviour had the probably surprising effect of converting a
661 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
662 2.
663 This may result in slightly different 8 or 16-bit output images.
664
e2a86bac
TC
665 - BI_BITFIELD BMP images were handled incorrectly, both in
666 incorrectly calculating the space required for the masks and in
667 processing the image data itself.
668 https://rt.cpan.org/Ticket/Display.html?id=76736
669
670 - some odd width BMP BI_RLE4 images use run lengths that run one off
671 the edge of the image. Imager now allows this, discarding the
672 extra column.
673
674 - odd length RLE4 runs in BMP images were decoded incorrectly.
675
82eb0687
TC
676 - pkg-config could sometimes return a library that was in a directory
677 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
678 If no -L is included in the pkg-config library information check if
679 EU::MM can find the library, and if not, search our configured
680 directories and insert that into the library flags.
681 https://rt.cpan.org/Ticket/Display.html?id=75869
682
de50f459
TC
683 - Imager::Probe can now probe for libraries with dependent libraries,
684 common for static linking, eg. libpng requires libz.
685 https://rt.cpan.org/Ticket/Display.html?id=74043
686
687 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
688
689 - added alternative probe configurations that try to link libz, to
690 handle a statically linked libpng.
691 https://rt.cpan.org/Ticket/Display.html?id=74043
692
693 - if a probe includes testcode, Imager::Probe now checks that code as
694 part of the process of checking each configuration rather than as a
695 post test of the found configuration. This allows alternate
696 configurations to be checked if a matching but non-working
697 configuration is found.

TC
773 - setsamples() is now a true complement to getsamples() - it can
774 write 8-bit or floating point samples from a scalar or array
775 reference. This adds i_psamp() and i_psampf() to the C level API.
776
777 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
778 changed to make better use of the typemap, but these aren't part of
779 the perl level API anyway. There were no changes to the C level
780 interfaces to these functions.

TC
932
933 - add simple tests for the Imager::Test test_image generators
934
6d5c85a2
TC
935 - io_glue I/O buffering re-work:
936
937 - reorganize io_glue to do it's own buffering by default
938
939 - the unbuffered functions are available as i_io_raw_read() (or
940 raw_read() from perl) etc but are not recommended for typical
941 use.
942
943 - use the new i_io_peekn() when checking for file magic to avoid
944 seek, allowing Imager to detect the file type and read the file
945 from an unseekable stream (for formats that don't use random
946 access)
947
948 - added several new I/O layer API functions.
949
950 - fix the TGA performance problem, most noticably on Win32
951 https://rt.cpan.org/Ticket/Display.html?id=70037
952
953 - TIFF now uses wrapper functions of the correct types to avoid casts
954 https://rt.cpan.org/Ticket/Display.html?id=69912
955
956 - the callback IO object did its own buffering, controlled by the
957 maxbuffer parameter supplied to the read() and write() methods.
958 This buffering has been removed, to avoid redundancy with the
959 common io_glue buffering. This also avoids a bug in that code
960 which could rarely pass a zero length to the read callback and
961 then panic about the result.
962
963 - the callback IO object now tests the result of calling the close
964 callback, which should return true for success.
965
966 - the PNM reader did its own buffering. This buffering has been
967 removed to avoid redundancy with the common io_glue buffering.
968
969 - previously the read handlers for fd and callback I/O layers would
970 call the underlying interface (POSIX read or your supplied callback)
971 until it filled the buffer. It now only makes one call.
972
973 - added public constructors for I/O layer objects (see Imager::IO)
974
975 - all core file handlers now use the i_io_foo() wrappers to gain
976 access to buffered I/O rather than calling the I/O layer
977 callbacks directly.
978
979 - all core file handlers now check for error on close.
980
981 - Backward compatibility: if you hava custom file handlers, you can
982 use i_io_write() etc since they're available as macros in older
983 versions of Imager.
984
985 - eliminate the final remnants of io_glue_commit_types().
986
987 - bump IMAGER_API_VERSION, since the above may break assumptions.
988
989 - removed the long unused i_gen_reader() and i_gen_writer() utility
990 functions.

1052
1053Development release as a sanity check for the types re-work.
8d14daab
TC
1054
1055Massive types re-work:
1056
1057 - the type used internally for pixel co-ordinates and image sizes is
1058 now 64-bit on 64-bit platforms (at least sane ones).
1059
1060 - size_t is now used consistently for memory block sizes.
1061
1062 - since this changes the binary interface, the Imager API version has
1063 been incremented. Any module that uses the API will need to be
1064 rebuilt. In most cases that will be enough, but calls to any APIs
1065 that take a pointer to image sizes may need source changes.
1066
1067 - you should be able to create very large images on 64-bit systems,
1068 if you have enough memory. Successfully created a 32768 x 49192 x
1069 3 channel image, filled with a tiled image and scaled it. The
1070 unscaled image was also successfully saved to a JPEG.
1071
1072 - check the image size before attempting to write BMP, GIF, JPEG,
1073 PNG, SGI, TGA, TIFF images.
1074
1075 - correctly handle reading TGA images over 32767 pixels wide or tall.
1076
1077Incidental changes:
1078
1079 - the gif_left and gif_top tags are now clamped to non-negative
1080 values when writing a GIF image.
1081
1082 - removed dead callback read/write code
1083
1084The default maximum memory size when reading files is now 1G.

1787 - some TGA images weren't being detected correctly as TGA images
1788 https://rt.cpan.org/Ticket/Display.html?id=32925
1789
1790 - handling of the left-over bit for 16-bit/pixel TGA images has been
1791 changed to match the behaviour of the GIMP. Previously the bit
1792 being set was treated as an opaque pixel, but one user reported a
1793 problem with loading such an image. I haven't been able to find any
1794 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1795 I'll match it's behaviour. See issue 114913 in the GIMP's
1796 bugzilla.

1806 - the old dynaload code used Mach API functions to load dynamic

2118
2119Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2120
2121There is one new feature:
2122
2123 - the Win32 font driver now supports UTF8 (RT 22166)

2125 http://rt.cpan.org/Ticket/Display.html?id=22166
2126
2127Several bugs were fixed:
2128
2129 - the string() method would not output the string "0"
2130 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2131
2132 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2133 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2134
2135 - the gif_disposal and gif_user_input tags weren't being read from
2136 the file correctly
2137 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2138
2139 - gif.c was failing to build under MSVC
2140 http://rt.cpan.org/Ticket/Display.html?id=23922
2141
2142 - in some cases strings passed to the string() method were treated as
2143 terminated by NUL (chr 0)
2144 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2145
2146 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2147 that's the default build name for zlib on Win32.
2148 http://rt.cpan.org/Ticket/Display.html?id=23064
2149
2150 - search $Config{incpath} for headers too, which we should have been
2151 doing all along.
2152
2153Win32 font driver fixes:
2154
2155 - the global descent value from bounding box was the wrong sign
2156 http://www.cpanforum.com/threads/3276
2157
2158 - if the first or last glyph overflowed the left or right side of the
2159 advance width they would be clipped
2160
2161
2162Imager 0.54 - 14 Sep 2006
2163===========
2164
2165This is primarily a feature release:
2166
2167 - a new qtype value 'mixing' has been added to the scale()
2168 method. This is faster than 'normal', slower than 'preview'. This
2169 is based on the method used by pnmscale, and seems to produce less
2170 blurry results than normal.
2171 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2172
2173 - the rubthrough() method can now render onto images with an alpha
2174 channel.
2175 http://rt.cpan.org/Ticket/Display.html?id=20678
2176
2177 - the read_multi() method now falls back to calling doing a single
2178 image read via the read() method and write_multi() will now fall
2179 back to calling write() if a single image is supplied. This means
2180 you can simply call the read_multi() or write_multi() functions
2181 without having to check if the type is formatted by that method.
2182 http://rt.cpan.org/Ticket/Display.html?id=19457
2183 http://rt.cpan.org/Ticket/Display.html?id=19458

2185 - the GIF loop extension can now be written. If you don't have
2186 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2187 should upgrade.

2203
2204This is a bugfix release.

2212Imager 0.52 - 25 Jul 2006
2213===========
2214
2215This is primarily a feature release, but contains a fair few bug
2216fixes, new features:
2217
2218 - ability to read and write MS Windows ICO and CUR files
2219
2220 - you can now add file format plugins to support new file formats
2221
2222 - add POD coverage tests
2223
2224 - setcolors() and addcolors() now accept color names and so on
2225 instead of requiring Imager::Color objects.
2226 http://rt.cpan.org/Ticket/Display.html?id=20056
2227
2228 - flood_fill() can now fill to a specified border color instead of
2229 just to the area the same color as the seed.
2230 http://rt.cpan.org/Ticket/Display.html?id=19618
2231
2232
2233Bug fixes:
2234
2235 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2236 calculating the advance width.
2237 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2238
2239 - bounding_box for the T1 driver wasn't including leading and
2240 trailing spaces in the bounding box as the other drivers did, it also
2241 produced strange results for empty strings or strings containing only
2242 spaces
2243
2244 - when reading CMYK jpeg images they were being transferred to the
2245 image object as is, producing a four channel image. It only looked ok
2246 due to an old still unfixed Photoshop bug. We now convert from the
2247 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2248 http://rt.cpan.org/Ticket/Display.html?id=20416
2249
2250 - reading a CYMK TIFF would result in a 4 channel image, reading any
2251 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2252 result in an error.
2253 http://rt.cpan.org/Ticket/Display.html?id=20415
2254
2255 - added /usr/local/include to the default include search path, since
2256 we were already searching /usr/local/lib for libraries.
2257
2258And various minor fixes and documentation updates.
