3Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
4================
5
08914ed1
TC
6 - re-work the t/200-file/400-basic.t to correctly handle failures
7 It's custom ok() function didn't have a prototype and didn't use scalar().
8 This caused ok() to use the note instead of the value being tested when
9 the method called returned an empty list. For an example of the problem
e6226ce5 10 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 11
a2791e47
TC
12 - remove some noise from when Imager tried to work with bugs in old
13 versions of giflib. I can't do much about the new bugs.
08914ed1 14
e6226ce5
TC
15 - the new autolevels filter (Imager 0.99) used an integer for the
16 sample scaling factor which caused the top output level to be too
17 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
18 https://rt.cpan.org/Ticket/Display.html?id=111871
19
e6226ce5 20 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
21 minimum and maximum luminance from the histogram. This slightly
22 reduced the contrast of the output image.
23 https://rt.cpan.org/Ticket/Display.html?id=111871
24
25 - the new autolevels filter now uses a lookup table for 8-bit images
26 to avoid a floating point multiply for each sample.
27 https://rt.cpan.org/Ticket/Display.html?id=111871
28
e6226ce5
TC
29 - fixed several memory leaks detected by valgrind:
30
31 - addcolors() leaked the temporary array of colors supplied to the
32 internal API
33
34 - make_palette() leaked the temporary image array (not the images
35 themselves) passed to the internal API.
36
37 - combine()/i_combine() leaked its working row buffers
38
39 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
40 buffer if there were too many colors
41
42 - getcolorcount()/i_count_colors() leaked the sample buffer if
43 there were too many colors.
44
45 - the nearest_color filter (undocumented until I find a use for it)
46 leaked both temporaries passed to the API and internal buffers
47
a2791e47
TC
48 - the internal process of upgrading a paletted image to a direct
49 color image would leak a context object reference count.
50
51 - a write failure when writing to a GIF file could leak memory.
52
53 - failing to write to a 1-bit/pixel ICO image could leak memory.
54
55 - Imager no longer deliberately leaks the context object from the
56 initial thread. This was done to ensure there was always a context
57 object available, but the code that needed that now handles the
58 lack correctly,
59
e6226ce5
TC
60 - fixed some uninitialized memory usage detected by valgrind:
61
62 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
63 i_matrix_transform_bg() didn't initialize a working color value
64 if there was zero pixel coverage.
65
66 - i_ft2_cp() didn't initialize the complete color when producing an
67 intermediate image. This caused uninitialized value usage when
68 logging the color.

70Imager 1.004 - 8 Nov 2015
71============
72
5ebfb369
TC
73 - Imager::Color::Table is now pre-loaded by the preload() method.
74 https://rt.cpan.org/Ticket/Display.html?id=104896
75
76 - fix an assertion triggered under perl 5.23.4.
77 Thanks to A. Sinan Unur for the report and the patch.
78
7b638aba
TC
79 - Imager->new can now be used to read raw image files.
80 https://rt.cpan.org/Ticket/Display.html?id=106836
f7160b21 81 Thanks to Richard Kelsch for reporting this.
7b638aba
TC
82
83 - deal with output changes from Pod::Spell

TC
86Imager 1.003 - 12 May 2015
87============
88
0fda3cfd
TC
89 - update 1.002 release notes to include the center change for filled
90 circle drawing.
91
92 - flood_fill() would escape beyond a 4-connected space under some
93 circumstances.
94 Added many more flood_fill() tests.

TC
97Imager 1.002 - 3 Apr 2015
98============
99
334b8922
TC
100 - drawing anti-aliased filled circles is now 10 to 50 times faster
101 depending on the size of the circle.
0fda3cfd
TC
102 This also changed the center from being the center of the pixel to
103 being the top left of the pixel to match the filled arcs drawn by
104 arc().
334b8922
TC
105 https://rt.cpan.org/Ticket/Display.html?id=101682
106
107 - enhancements to polygon filling:
108
109 - added a mode parameter to control how overlapping regions behave
110
111 - added a polypolygon() method to fill more than one polygon at a
112 time
113
114 - polygon filling is now exposed through the API.
115
45c8e262
TC
116 - added colormodel(), alphachannel() and colorchannels() methods.
117 These were added for two reasons:
118
119 - a future version of Imager may allow the number of channels in
120 an image to not directly represent the color model of an image.
121 eg. a greyscale TIFF image with multiple alpha channels.
122
123 - a future version of Imager may allow an image to be read without
124 translation, for example a TIFF file that contains measurements
0fda3cfd 125 from an instrument. Currently Imager transforms the samples into
45c8e262
TC
126 the range 0.0 ... 1.0 which may means the user has to translates
127 the value back.
128
129 An untranslated image would be unusable as image data, so
130 colormodel() would return "unknown" in this case.
131
132 Similarly a CMYK image might be returned as an "unknown" color
133 model image, if the caller chooses to disable translation to
134 RGB.

136Imager 1.001 - 2 Jan 2015
137============
138
aca60e01
TC
139 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
140 Thanks to Slaven Rezic for the report and the patch.
141 https://rt.cpan.org/Public/Bug/Display.html?id=98234
142
0df260f6
TC
143 - GIF: clean-up a test file if the test for the giflib 4.2.0 file
144 version bug fails.
145
146 - fix Imager::Matrix2d::rotate()'s centre point handling
147 https://rt.cpan.org/Public/Bug/Display.html?id=99959
148
149 - ICO: don't apply the icon mask to images with an alpha channel by
150 default
151 https://rt.cpan.org/Public/Bug/Display.html?id=99507
152
56605f3f
TC
153 - make verbose probing output more verbose

f74bd978
TC
155 - use Imager::Probe to probe for freetype 1.x
156 https://rt.cpan.org/Ticket/Display.html?id=100502
157
158 - The --enable and --disable parameters to the top-level Makefile.PL
159 work again.
160
c7f06039
TC
161 - update the bundled/modified Devel::CheckLib to handle the gcc-4
162 symlink on Cygwin

TC
164Imager 1.000 - 28 Jul 2014
165============
166
167There's nothing special about Imager 1.000, it's just another release.
168
fa3dac1d
TC
169 - fix the skip check for the iolayer qr// buffer test
170
171 - improve error reporting for the iolayer test failing on a small
172 number of Win32 CPAN testers
173

TC
174Imager 0.99_02 - 21 Jul 2014
175==============
176
5dab5b9a
TC
177 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
178 the blue channel in the generated palette, and allow each color
179 component to be in the range 100..255 instead of just 100..254.
180 Thanks to Ralf Neubauer.
181 https://rt.cpan.org/Ticket/Display.html?id=97086
182
183 - revert "improved the XS for i_io_read() and i_io_raw_read()"
184 This caused problems with older perls and didn't provide much of a
185 performance improvement.
186
5bf25bc2 187 - support Inline 0.57 and later.
6d47a6af 188 Inline 0.57 changed the "with" interface.
5bf25bc2
TC
189 https://rt.cpan.org/Ticket/Display.html?id=97108
190
6d47a6af
TC
191 - don't define our own MAXINT macro, it conflicts with windows header
192 files and in a few places it was the wrong value to use anyway.
193 https://rt.cpan.org/Ticket/Display.html?id=96425

TC
195Imager 0.99_01 - 29 Jun 2014
196==============
197
7b486870
TC
198 - GIF: add support for giflib 5.1.0, which added error code pointer
199 parameters to EGifCloseFile() and DGifCloseFile().
200 https://rt.cpan.org/Ticket/Display.html?id=96756
201
202 - GIF: avoid a double-free when do_write() fails.
203
28104a85 204 - fix SV type probing to work on perl before 5.12. Broken in 0.99.
ea87cee9
TC
205 https://rt.cpan.org/Ticket/Display.html?id=96761
206
df04d4b3
TC
207 - PNG: skip the benign error test before libpng 1.6.0, since the
208 error we're testing didn't exist before 1.6.0.
209 https://rt.cpan.org/Ticket/Display.html?id=94717 (continued)

211Imager 0.99 - 25 Jun 2014
212===========
213
dce1523b
TC
214 - Imager::IO->new_buffer() (and hence Imager->read()'s data
215 parameter) now accepts a reference to a scalar as well as just a
216 plain scalar.
6a160bce 217 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
218
219 - Imager::IO->new_buffer() now always makes a copy of the passed in
220 buffer to avoid problems with temporary objects used for the return
221 value of SvPVbyte().
6a160bce 222 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 223
c757e211
TC
224 - improved the XS for i_io_read() and i_io_raw_read()
225 https://rt.cpan.org/Ticket/Display.html?id=92738
226
227 - load plugins from absolute paths on Android
228 Thanks to Brian Fraser.
229 https://rt.cpan.org/Ticket/Display.html?id=93272
230
6a160bce
TC
231 - added the jpeg_optimize parameter for writing JPEG files. This can
232 significantly reduce file sizes, but uses more memory and time.
233 https://rt.cpan.org/Ticket/Display.html?id=94292
234
14fd9e5d
TC
235 - the autolevels filter now works on the luminosity of the image
236 rather then working per channel. The old autolevels filter is
237 still available as "autolevels_skew".
238 https://rt.cpan.org/Ticket/Display.html?id=94413
239
75d54149
TC
240 - Imager::File::PNG now supports libpng 1.6.10.
241 1.6.10 changed CRC errors from benign errors to normal errors,
242 which broke the test which used CRC errors to check for benign
243 error support. Switched to using a 1-bit grey-scale image with a
244 palette to test for benign errors.
245 https://rt.cpan.org/Ticket/Display.html?id=94717

TC
247Imager 0.98 - 3 Jan 2014
248===========
249
f84f86a2
TC
250Incompatible changes:
251
252 - the return value of setpixel() has changed.
253
254 Previously the return values for undrawable pixels vs caller errors
255 changed depending on whether you used the multiple pixel calling
256 mechanism, or the single pixel mechanism.
257
258 Now:
259
260 - for an invalid parameter, such as an unknown colour, or missing
261 parameter, an empty list (or undef in scalar context) is
262 returned, and errstr() is set,
263
264 - otherwise the number of pixels drawn is returned. If none of
265 the pixels could be drawn (they were all outside the image), "0
266 but true" is returned.
267
268 https://rt.cpan.org/Ticket/Display.html?id=87650
269
270Other changes:
271
6ba09ab9
TC
272 - when drawing on an image with an alpha channel where the source
273 minimum is greater than zero, Imager would read from beyond the end
274 of a malloc() allocated buffer. In rare circumstances this could
275 lead to some of the source image not being written to the target
276 image, or possibly to a segmentation fault.
277 I don't believe this has any security concerns beyond that.
278
0d052fd9
TC
279 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
280 text drawn would be nonsense. This would also read beyond the end
281 of a malloced buffer.
282
13671b17
TC
283 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
284 truncated early.
285 https://rt.cpan.org/Ticket/Display.html?id=88993
286
d6f4e964
TC
287 - Imager::Font::Wrap no longer requires the image parameter.
288 https://rt.cpan.org/Ticket/Display.html?id=87338
289
f84f86a2
TC
290 - a documentation typo fix in Imager::Transformations
291 Thanks to Adrian Yee.
292 https://rt.cpan.org/Ticket/Display.html?id=88598
293
0179ecd6
TC
294 - Image::Probe, Imager's internal module for probing library
295 locations now searches the directories specified by LD_RUN_PATH,
296 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
297 and the corresponing s/\blib$/include/ directories for header
298 files.

306Imager 0.96_02 - 8 Jul 2013
307==============
308
aaf82685
TC
309 - PNG: treat a version mismatch between headers and library as a
310 probe failure.
311 https://rt.cpan.org/Ticket/Display.html?id=86659
312
8e90f677
TC
313 - PNG: the check for benign error support is more complex than a
314 simple library version check, check for the appropriate macro.
315 Thanks for Slaven Rezic for following up on my CPAN Testers result
316 queries.
317 https://rt.cpan.org/Ticket/Display.html?id=86659

TC
323==============
324
05c9b356
TC
325 - TIFF: handle SampleFormat = 2 by translating the signed integer
326 values to unsigned by flipping their sign bits.
327
328 Handle SampleFormat = 3 where possible.
329
330 SampleFormat is ignored for paletted images.
331
237d9e03
TC
332 Mixed SampleFormat are handled incorrectly, since libtiff returns
333 only the first SampleFormat value, and an image with both an alpha
334 channel and SampleFormat = 2 for color channels probably has a
335 different SampleFormat for the alpha channel.

face45e7 339 - XS clean up:
29969fa2 340 https://rt.cpan.org/Ticket/Display.html?id=69243
face45e7 341
237d9e03 342 - Imager::Color's rgba() method now returns its values as integers
face45e7
TC
343 instead of floating point. (IV instead of NV).
344
19e9591b
TC
345 - The XS for i_map() and i_matrix_transform() now use the AV *
346 typemap instead of rolling their own.
347
75cebca8
TC
348 - The XS for DSO_call() now uses the HV * typemap instead of
349 rolling it's own.
350
0aaa8b4d
TC
351 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
352 i_gradgen() now use a new T_AVARRAY typemap that greatly
353 simplifies the XS code.
face45e7 354
ccd01d49
TC
355 - many other minor XS changes
356
face45e7 357 - some XS code formatting
a54e32ba 358
dcab59bc
TC
359 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
360 now renders in alpha-combining mode, to match antialiased output.
361 https://rt.cpan.org/Ticket/Display.html?id=73359
b482243a 362
8db7b6fa
TC
363 - add sample code and cookbook notes for drawing a blurred drop-shadow.
364
365 - add support for libpng 1.6, which changed the defaults for
366 reporting some types of error.
367 https://rt.cpan.org/Ticket/Display.html?id=85746
368
dc076f98
TC
369 - FT2: use gsamp/psamp() to transfer pixels from the work image to
370 the output image instead of gpix/ppix.
371 https://rt.cpan.org/Ticket/Display.html?id=83478

376Imager 0.96 - 19 May 2013
377===========
378
c2e251d9
TC
379 - rearrange Imager's test files.
380 https://rt.cpan.org/Ticket/Display.html?id=84596
381
382 - Imager::Probe::_gcc_lib_paths now forces C locale.
383 A sufficiently recent gcc prints localized keys for the search
384 paths, which avoids that localization.
385 https://rt.cpan.org/Ticket/Display.html?id=84963
386
387 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
388 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
389 and true.
390 https://rt.cpan.org/Ticket/Display.html?id=85262
391 reported by Andreas König
392
393 - add a test for unclosed POD in C source, and fix the errors it
394 found.
395 https://rt.cpan.org/Ticket/Display.html?id=74875
396
397 - fix some spelling errors detected by the newer aspell in Debian
398 Wheezy.
399
400 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
401 thanks to gregor herrmann <gregoa@debian.org>
402 https://rt.cpan.org/Ticket/Display.html?id=85413
403
404 - add a test for standard =head1 commands and fix the errors found

TC
406Imager 0.95 - 19 Apr 2013
407===========
408
0a2956ab
TC
409 - handle the SVf_UTF8 flag correctly on magic strings passed to
410 Imager::IO's write() and raw_write() methods.
411 This may misbehave in perl 5.6.x since the UTF8 flag may not be
412 visible in the main SV after SvGETMAGIC().
413 https://rt.cpan.org/Ticket/Display.html?id=83438
414
415 - document that bounding_box() ignores the transformation matrix
416 supplied to tranform() for fonts.

TC
419Imager 0.94_02 - 5 Apr 2013
420==============
421
1540d1d4
TC
422 - enable debug logging for the standard font tests
423
424 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
425 due to a bug in that version of perl.
426
427 - don't test for read() failing on a write-only handle in 5.8.x and
428 earlier, this was fixed in change 862083f7e4 in perl.
429
430 - report the version of Inline found during testing (an attempt to
431 diagnose some intermittent failures.)

TC
433Imager 0.94_01 - 2 Mar 2013
434==============
435
14a4ea18 436 - NOTE: possibly backward incompatible:
3dcf7595
TC
437 support reading from/writing to perl filehandes that aren't raw
438 files.
439
440 This allows Imager's I/O to honour handles with layers such as
441 gzip, scalar file handles or tied file handles.
442
14a4ea18 443 This is backward incompatible in that previous Imager would simply
3dcf7595
TC
444 use fileno() to retrieve the fd for the file and call write(2) etc
445 on it directly.
04d8c568
TC
446 https://rt.cpan.org/Ticket/Display.html?id=78843
447
448 - moved most of README to lib/Imager/Install.pod which should make it
449 more accessible to the "web" generation, also significantly updated
450 and re-worked it.
3dcf7595 451
ca96f811

544Enhancements:
545
546 - support for giflib 5.0. (5.0.1 and later)
547 https://rt.cpan.org/Ticket/Display.html?id=79029
548 The giflib API Imager uses doesn't have a mechanism to set the
549 header version in 5.0.0.
550
551 - update the GIF library probe code to check for the new giflib 5.0.1
552 EGifSetGifVersion() function, and to check for the giflib 4.2.0
553 uninitialized gif89 bug.

555 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
556
557 - avoid static variables when capturing IPTC data from JPEG files
558
559 - match Imager::Font;:T1's error message translations to those from
560 later versions of T1Lib.
561
562 - for libtiff versions that support extended warning handlers (3.8.0
563 or later), use them to avoid some global variables.

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

616===========
617
618Bug fixes:

620 - Imager::Test::is_imaged() attempted to process an "epsilon"
621 parameter but the prototype didn't allow for the extra parameter.
622 Corrected the prototype.
623
29b38678
TC
624 - when downconverting samples (eg. from floating point to 8 bit)
625 Imager now rounds the sample value rather than attempting to
626 allocate input values over output values equally. The old
627 behaviour had the probably surprising effect of converting a
628 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
629 2.
630 This may result in slightly different 8 or 16-bit output images.
631
e2a86bac
TC
632 - BI_BITFIELD BMP images were handled incorrectly, both in
633 incorrectly calculating the space required for the masks and in
634 processing the image data itself.
635 https://rt.cpan.org/Ticket/Display.html?id=76736
636
637 - some odd width BMP BI_RLE4 images use run lengths that run one off
638 the edge of the image. Imager now allows this, discarding the
639 extra column.
640
641 - odd length RLE4 runs in BMP images were decoded incorrectly.
642
82eb0687
TC
643 - pkg-config could sometimes return a library that was in a directory
644 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
645 If no -L is included in the pkg-config library information check if
646 EU::MM can find the library, and if not, search our configured
647 directories and insert that into the library flags.
648 https://rt.cpan.org/Ticket/Display.html?id=75869
649
de50f459
TC
650 - Imager::Probe can now probe for libraries with dependent libraries,
651 common for static linking, eg. libpng requires libz.
652 https://rt.cpan.org/Ticket/Display.html?id=74043
653
654 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
655
656 - added alternative probe configurations that try to link libz, to
657 handle a statically linked libpng.
658 https://rt.cpan.org/Ticket/Display.html?id=74043
659
660 - if a probe includes testcode, Imager::Probe now checks that code as
661 part of the process of checking each configuration rather than as a
662 post test of the found configuration. This allows alternate
663 configurations to be checked if a matching but non-working
664 configuration is found.

671 called but not supplied.

740 - setsamples() is now a true complement to getsamples() - it can
741 write 8-bit or floating point samples from a scalar or array
742 reference. This adds i_psamp() and i_psampf() to the C level API.
743
744 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
745 changed to make better use of the typemap, but these aren't part of
746 the perl level API anyway. There were no changes to the C level

TC
899
900 - add simple tests for the Imager::Test test_image generators
901
6d5c85a2
TC
902 - io_glue I/O buffering re-work:
903
904 - reorganize io_glue to do it's own buffering by default
905
906 - the unbuffered functions are available as i_io_raw_read() (or
907 raw_read() from perl) etc but are not recommended for typical
908 use.
909
910 - use the new i_io_peekn() when checking for file magic to avoid
911 seek, allowing Imager to detect the file type and read the file
912 from an unseekable stream (for formats that don't use random
913 access)
914
915 - added several new I/O layer API functions.
916
917 - fix the TGA performance problem, most noticably on Win32
918 https://rt.cpan.org/Ticket/Display.html?id=70037
919
920 - TIFF now uses wrapper functions of the correct types to avoid casts
921 https://rt.cpan.org/Ticket/Display.html?id=69912
922
923 - the callback IO object did its own buffering, controlled by the
924 maxbuffer parameter supplied to the read() and write() methods.
925 This buffering has been removed, to avoid redundancy with the
926 common io_glue buffering. This also avoids a bug in that code
927 which could rarely pass a zero length to the read callback and
928 then panic about the result.
929
930 - the callback IO object now tests the result of calling the close
931 callback, which should return true for success.
932
933 - the PNM reader did its own buffering. This buffering has been
934 removed to avoid redundancy with the common io_glue buffering.
935
936 - previously the read handlers for fd and callback I/O layers would
937 call the underlying interface (POSIX read or your supplied callback)
938 until it filled the buffer. It now only makes one call.
939
940 - added public constructors for I/O layer objects (see Imager::IO)
941
942 - all core file handlers now use the i_io_foo() wrappers to gain
943 access to buffered I/O rather than calling the I/O layer
944 callbacks directly.
945
946 - all core file handlers now check for error on close.
947
948 - Backward compatibility: if you hava custom file handlers, you can
949 use i_io_write() etc since they're available as macros in older
950 versions of Imager.
951
952 - eliminate the final remnants of io_glue_commit_types().
953
954 - bump IMAGER_API_VERSION, since the above may break assumptions.
955
956 - removed the long unused i_gen_reader() and i_gen_writer() utility
957 functions.

965 dimensions and co-ordinated, and for memory block sizes.
966

968 lead to an infinite loop.

1019
1020Development release as a sanity check for the types re-work.
8d14daab
TC
1021
1022Massive types re-work:
1023
1024 - the type used internally for pixel co-ordinates and image sizes is
1025 now 64-bit on 64-bit platforms (at least sane ones).
1026
1027 - size_t is now used consistently for memory block sizes.
1028
1029 - since this changes the binary interface, the Imager API version has
1030 been incremented. Any module that uses the API will need to be
1031 rebuilt. In most cases that will be enough, but calls to any APIs
1032 that take a pointer to image sizes may need source changes.
1033
1034 - you should be able to create very large images on 64-bit systems,
1035 if you have enough memory. Successfully created a 32768 x 49192 x
1036 3 channel image, filled with a tiled image and scaled it. The
1037 unscaled image was also successfully saved to a JPEG.
1038
1039 - check the image size before attempting to write BMP, GIF, JPEG,
1040 PNG, SGI, TGA, TIFF images.
1041
1042 - correctly handle reading TGA images over 32767 pixels wide or tall.
1043
1044Incidental changes:
1045
1046 - the gif_left and gif_top tags are now clamped to non-negative
1047 values when writing a GIF image.
1048
1049 - removed dead callback read/write code
1050
1051The default maximum memory size when reading files is now 1G.

1705
1706 - rubthrough() now falls back to pasting when the source doesn't have
1707 an alpha channel. This effectively treats the source as having a
1708 max alpha channel, the right thing to do.

1715 defines them with respect to a translucent source and destination.

1773 - the old dynaload code used Mach API functions to load dynamic
1774 libraries on Mac OS X. These APIs have been deprecated in OS X
1775 10.5 and were causing some build problems.
1776 So henceforth Imager uses the dlopen() family of functions, and you
1777 will need version 10.3 or later of OS X.

2082===========
2083
2084This is primarily a bug fix release.
2085
2086Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2087
2088There is one new feature:
2089
2090 - the Win32 font driver now supports UTF8 (RT 22166)
2091 http://www.cpanforum.com/threads/3276
2092 http://rt.cpan.org/Ticket/Display.html?id=22166
2093
2094Several bugs were fixed:
2095
2096 - the string() method would not output the string "0"
2097 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2098
2099 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2100 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2101
2102 - the gif_disposal and gif_user_input tags weren't being read from
2103 the file correctly
2104 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2105
2106 - gif.c was failing to build under MSVC
2107 http://rt.cpan.org/Ticket/Display.html?id=23922
2108
2109 - in some cases strings passed to the string() method were treated as
2110 terminated by NUL (chr 0)
2111 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2112
2113 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2114 that's the default build name for zlib on Win32.
2115 http://rt.cpan.org/Ticket/Display.html?id=23064
2116
2117 - search $Config{incpath} for headers too, which we should have been
2118 doing all along.
2119
2120Win32 font driver fixes:
2121
2122 - the global descent value from bounding box was the wrong sign
2123 http://www.cpanforum.com/threads/3276
2124
2125 - if the first or last glyph overflowed the left or right side of the
2126 advance width they would be clipped

2128
2129Imager 0.54 - 14 Sep 2006
2130===========
2131
2132This is primarily a feature release:
2133
2134 - a new qtype value 'mixing' has been added to the scale()
2135 method. This is faster than 'normal', slower than 'preview'. This
2136 is based on the method used by pnmscale, and seems to produce less
2137 blurry results than normal.
2138 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2139
2140 - the rubthrough() method can now render onto images with an alpha
2141 channel.
2142 http://rt.cpan.org/Ticket/Display.html?id=20678
2143
2144 - the read_multi() method now falls back to calling doing a single
2145 image read via the read() method and write_multi() will now fall
2146 back to calling write() if a single image is supplied. This means
2147 you can simply call the read_multi() or write_multi() functions
2148 without having to check if the type is formatted by that method.
2149 http://rt.cpan.org/Ticket/Display.html?id=19457
2150 http://rt.cpan.org/Ticket/Display.html?id=19458
2151
2152 - the GIF loop extension can now be written. If you don't have
2153 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2154 should upgrade.
2155 http://rt.cpan.org/Ticket/Display.html?id=21185
2156
2157 - getscanline() and setscanline() can now read/write palette index
2158 based data from/to the image for paletted images, by setting type to
2159 'index'.
2160 http://rt.cpan.org/Ticket/Display.html?id=20338
2161
2162 - we no longer hassle you to disable GIF support
2163 http://rt.cpan.org/Ticket/Display.html?id=20687
2164
2165 - minor documentation fixes
2166
2167
2168Imager 0.53 - 26 Jul 2006
2169===========
2170
2171This is a bugfix release.
2172
2173Some test code was left in a code path not covered by the test
2174suite. A test was added to cover this code path and the test code was
2175removed.

2180===========
2181
2182This is primarily a feature release, but contains a fair few bug
2183fixes, new features:
2184
2185 - ability to read and write MS Windows ICO and CUR files
2186
2187 - you can now add file format plugins to support new file formats
2188
2189 - add POD coverage tests
2190
2191 - setcolors() and addcolors() now accept color names and so on
2192 instead of requiring Imager::Color objects.
2193 http://rt.cpan.org/Ticket/Display.html?id=20056
2194
2195 - flood_fill() can now fill to a specified border color instead of

2200Bug fixes:
2201
2202 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2203 calculating the advance width.
2204 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2205
2206 - bounding_box for the T1 driver wasn't including leading and
2207 trailing spaces in the bounding box as the other drivers did, it also
2208 produced strange results for empty strings or strings containing only
2209 spaces
2210
2211 - when reading CMYK jpeg images they were being transferred to the
2212 image object as is, producing a four channel image. It only looked ok
2213 due to an old still unfixed Photoshop bug. We now convert from the
2214 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2215 http://rt.cpan.org/Ticket/Display.html?id=20416
2216
2217 - reading a CYMK TIFF would result in a 4 channel image, reading any
2218 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2219 result in an error.

2221
2222 - added /usr/local/include to the default include search path, since
2223 we were already searching /usr/local/lib for libraries.
