TC
3 - re-work the t/200-file/400-basic.t to correctly handle failures
4 It's custom ok() function didn't have a prototype and didn't use scalar().
5 This caused ok() to use the note instead of the value being tested when
6 the method called returned an empty list. For an example of the problem
7 caused, see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
8
9 - remove some noise from when Imager tried to work with buggy
10 versions of giflib.
11
12 - the new autolevels filter (0.99) used an integer for the sample
13 scaling factor which caused the top output level to be too low
14 (depending on the scaling required.) It now uses a double.
15 https://rt.cpan.org/Ticket/Display.html?id=111871
16
17 - the new autolevels filter had off-by-one errors calculation the
18 minimum and maximum luminance from the histogram. This slightly
19 reduced the contrast of the output image.
20 https://rt.cpan.org/Ticket/Display.html?id=111871
21
22 - the new autolevels filter now uses a lookup table for 8-bit images
23 to avoid a floating point multiply for each sample.
24 https://rt.cpan.org/Ticket/Display.html?id=111871
25
26 - the addcolors() method leaked memory.

45============
46
0fda3cfd
TC
47 - update 1.002 release notes to include the center change for filled
48 circle drawing.
49
50 - flood_fill() would escape beyond a 4-connected space under some
51 circumstances.
52 Added many more flood_fill() tests.

TC
55Imager 1.002 - 3 Apr 2015
56============
57
334b8922
TC
58 - drawing anti-aliased filled circles is now 10 to 50 times faster
59 depending on the size of the circle.
0fda3cfd
TC
60 This also changed the center from being the center of the pixel to
61 being the top left of the pixel to match the filled arcs drawn by
62 arc().

TC
63 https://rt.cpan.org/Ticket/Display.html?id=101682
64
65 - enhancements to polygon filling:
66
67 - added a mode parameter to control how overlapping regions behave
68
69 - added a polypolygon() method to fill more than one polygon at a
70 time
71
72 - polygon filling is now exposed through the API.
73
45c8e262
TC
74 - added colormodel(), alphachannel() and colorchannels() methods.
75 These were added for two reasons:
76
77 - a future version of Imager may allow the number of channels in
78 an image to not directly represent the color model of an image.
79 eg. a greyscale TIFF image with multiple alpha channels.
80
81 - a future version of Imager may allow an image to be read without
82 translation, for example a TIFF file that contains measurements
0fda3cfd 83 from an instrument. Currently Imager transforms the samples into
45c8e262
TC
84 the range 0.0 ... 1.0 which may means the user has to translates
85 the value back.
86
87 An untranslated image would be unusable as image data, so
88 colormodel() would return "unknown" in this case.
89
90 Similarly a CMYK image might be returned as an "unknown" color
91 model image, if the caller chooses to disable translation to
92 RGB.

133==============
134
5dab5b9a
TC
135 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
136 the blue channel in the generated palette, and allow each color
137 component to be in the range 100..255 instead of just 100..254.
138 Thanks to Ralf Neubauer.
139 https://rt.cpan.org/Ticket/Display.html?id=97086
140
141 - revert "improved the XS for i_io_read() and i_io_raw_read()"
142 This caused problems with older perls and didn't provide much of a
143 performance improvement.
144
5bf25bc2 145 - support Inline 0.57 and later.
6d47a6af 146 Inline 0.57 changed the "with" interface.

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

7b486870
TC
156 - GIF: add support for giflib 5.1.0, which added error code pointer
157 parameters to EGifCloseFile() and DGifCloseFile().
158 https://rt.cpan.org/Ticket/Display.html?id=96756
159
160 - GIF: avoid a double-free when do_write() fails.
161
28104a85 162 - fix SV type probing to work on perl before 5.12. Broken in 0.99.

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

169Imager 0.99 - 25 Jun 2014
170===========
171
dce1523b
TC
172 - Imager::IO->new_buffer() (and hence Imager->read()'s data
173 parameter) now accepts a reference to a scalar as well as just a
174 plain scalar.
6a160bce 175 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
176
177 - Imager::IO->new_buffer() now always makes a copy of the passed in
178 buffer to avoid problems with temporary objects used for the return
179 value of SvPVbyte().
6a160bce 180 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 181
c757e211
TC
182 - improved the XS for i_io_read() and i_io_raw_read()
183 https://rt.cpan.org/Ticket/Display.html?id=92738
184
185 - load plugins from absolute paths on Android
186 Thanks to Brian Fraser.
187 https://rt.cpan.org/Ticket/Display.html?id=93272
188
6a160bce
TC
189 - added the jpeg_optimize parameter for writing JPEG files. This can
190 significantly reduce file sizes, but uses more memory and time.
191 https://rt.cpan.org/Ticket/Display.html?id=94292
192
14fd9e5d
TC
193 - the autolevels filter now works on the luminosity of the image
194 rather then working per channel. The old autolevels filter is
195 still available as "autolevels_skew".
196 https://rt.cpan.org/Ticket/Display.html?id=94413
197
75d54149
TC
198 - Imager::File::PNG now supports libpng 1.6.10.
199 1.6.10 changed CRC errors from benign errors to normal errors,
200 which broke the test which used CRC errors to check for benign
201 error support. Switched to using a 1-bit grey-scale image with a
202 palette to test for benign errors.

205Imager 0.98 - 3 Jan 2014
206===========
207
f84f86a2
TC
208Incompatible changes:
209
210 - the return value of setpixel() has changed.
211
212 Previously the return values for undrawable pixels vs caller errors
213 changed depending on whether you used the multiple pixel calling
214 mechanism, or the single pixel mechanism.
215
216 Now:
217
218 - for an invalid parameter, such as an unknown colour, or missing
219 parameter, an empty list (or undef in scalar context) is
220 returned, and errstr() is set,
221
222 - otherwise the number of pixels drawn is returned. If none of
223 the pixels could be drawn (they were all outside the image), "0
224 but true" is returned.
225
226 https://rt.cpan.org/Ticket/Display.html?id=87650
227
228Other changes:
229
6ba09ab9
TC
230 - when drawing on an image with an alpha channel where the source
231 minimum is greater than zero, Imager would read from beyond the end
232 of a malloc() allocated buffer. In rare circumstances this could
233 lead to some of the source image not being written to the target
234 image, or possibly to a segmentation fault.
235 I don't believe this has any security concerns beyond that.
236
0d052fd9
TC
237 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
238 text drawn would be nonsense. This would also read beyond the end
239 of a malloced buffer.
240
13671b17
TC
241 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
242 truncated early.
243 https://rt.cpan.org/Ticket/Display.html?id=88993
244
d6f4e964
TC
245 - Imager::Font::Wrap no longer requires the image parameter.
246 https://rt.cpan.org/Ticket/Display.html?id=87338
247
f84f86a2
TC
248 - a documentation typo fix in Imager::Transformations
249 Thanks to Adrian Yee.
250 https://rt.cpan.org/Ticket/Display.html?id=88598
251
0179ecd6
TC
252 - Image::Probe, Imager's internal module for probing library
253 locations now searches the directories specified by LD_RUN_PATH,
254 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
255 and the corresponing s/\blib$/include/ directories for header
256 files.

264Imager 0.96_02 - 8 Jul 2013
265==============
266
aaf82685
TC
267 - PNG: treat a version mismatch between headers and library as a
268 probe failure.
269 https://rt.cpan.org/Ticket/Display.html?id=86659
270
8e90f677
TC
271 - PNG: the check for benign error support is more complex than a
272 simple library version check, check for the appropriate macro.
273 Thanks for Slaven Rezic for following up on my CPAN Testers result
274 queries.

TC
281==============
282
05c9b356
TC
283 - TIFF: handle SampleFormat = 2 by translating the signed integer
284 values to unsigned by flipping their sign bits.
285
286 Handle SampleFormat = 3 where possible.
287
288 SampleFormat is ignored for paletted images.
289
237d9e03
TC
290 Mixed SampleFormat are handled incorrectly, since libtiff returns
291 only the first SampleFormat value, and an image with both an alpha
292 channel and SampleFormat = 2 for color channels probably has a
293 different SampleFormat for the alpha channel.

face45e7 297 - XS clean up:
29969fa2 298 https://rt.cpan.org/Ticket/Display.html?id=69243
face45e7 299
237d9e03 300 - Imager::Color's rgba() method now returns its values as integers
face45e7
TC
301 instead of floating point. (IV instead of NV).
302
19e9591b
TC
303 - The XS for i_map() and i_matrix_transform() now use the AV *
304 typemap instead of rolling their own.
305
75cebca8
TC
306 - The XS for DSO_call() now uses the HV * typemap instead of
307 rolling it's own.
308
0aaa8b4d
TC
309 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
310 i_gradgen() now use a new T_AVARRAY typemap that greatly
311 simplifies the XS code.
face45e7 312
ccd01d49
TC
313 - many other minor XS changes
314
face45e7 315 - some XS code formatting
a54e32ba 316
dcab59bc
TC
317 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
318 now renders in alpha-combining mode, to match antialiased output.
319 https://rt.cpan.org/Ticket/Display.html?id=73359
b482243a 320
8db7b6fa
TC
321 - add sample code and cookbook notes for drawing a blurred drop-shadow.
322
323 - add support for libpng 1.6, which changed the defaults for
324 reporting some types of error.

326
dc076f98
TC
327 - FT2: use gsamp/psamp() to transfer pixels from the work image to
328 the output image instead of gpix/ppix.
329 https://rt.cpan.org/Ticket/Display.html?id=83478

336
c2e251d9
TC
337 - rearrange Imager's test files.
338 https://rt.cpan.org/Ticket/Display.html?id=84596
339
340 - Imager::Probe::_gcc_lib_paths now forces C locale.
341 A sufficiently recent gcc prints localized keys for the search
342 paths, which avoids that localization.
343 https://rt.cpan.org/Ticket/Display.html?id=84963
344
345 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
346 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
347 and true.
348 https://rt.cpan.org/Ticket/Display.html?id=85262
349 reported by Andreas König
350

352 found.
353 https://rt.cpan.org/Ticket/Display.html?id=74875
354
355 - fix some spelling errors detected by the newer aspell in Debian
356 Wheezy.
357
358 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
359 thanks to gregor herrmann <gregoa@debian.org>
360 https://rt.cpan.org/Ticket/Display.html?id=85413

TC
364Imager 0.95 - 19 Apr 2013
365===========
366
0a2956ab
TC
367 - handle the SVf_UTF8 flag correctly on magic strings passed to
368 Imager::IO's write() and raw_write() methods.
369 This may misbehave in perl 5.6.x since the UTF8 flag may not be
370 visible in the main SV after SvGETMAGIC().
371 https://rt.cpan.org/Ticket/Display.html?id=83438
372
373 - document that bounding_box() ignores the transformation matrix
374 supplied to tranform() for fonts.

378==============
379
1540d1d4
TC
380 - enable debug logging for the standard font tests
381
382 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
383 due to a bug in that version of perl.
384
385 - don't test for read() failing on a write-only handle in 5.8.x and
386 earlier, this was fixed in change 862083f7e4 in perl.
387
388 - report the version of Inline found during testing (an attempt to
389 diagnose some intermittent failures.)

392==============
393
14a4ea18 394 - NOTE: possibly backward incompatible:
3dcf7595
TC
395 support reading from/writing to perl filehandes that aren't raw
396 files.
397
398 This allows Imager's I/O to honour handles with layers such as
399 gzip, scalar file handles or tied file handles.
400
14a4ea18 401 This is backward incompatible in that previous Imager would simply
3dcf7595
TC
402 use fileno() to retrieve the fd for the file and call write(2) etc
403 on it directly.
04d8c568
TC
404 https://rt.cpan.org/Ticket/Display.html?id=78843
405
406 - moved most of README to lib/Imager/Install.pod which should make it
407 more accessible to the "web" generation, also significantly updated
408 and re-worked it.
3dcf7595 409
ca96f811
TC
410 - updated README's for the separately distributed modules to refer to
411 Imager::Install, and that they need -dev versions of packages
412 https://rt.cpan.org/Ticket/Display.html?id=81265
413
26e8a226
TC
414 - the JPEG test code now reports the compile-time library version

c732ffa5
TC
426 - drawing text to a channel with FT2 would draw with random coverage
427 due to an uninitialized alpha channel.
428
429 - marked the function pointer underlying the mm_log() API with the
430 correct gcc magic and fixed the resulting warnings.
431
432 - fixed some other compiler warnings
433
14a4ea18
TC
434 - Imager::Font::W32 now properly reports text drawing errors

TC
438 strings passed as text to draw(), bounding_box(), has_chars(),
439 glyph_names() (where supported) in each of the font drivers.

TC
478
479 - previously a transparency enabled GIF write (the default) would
480 always use a GIF89a header even if none of the images were
481 transparent.

502Enhancements:
503
504 - support for giflib 5.0. (5.0.1 and later)
505 https://rt.cpan.org/Ticket/Display.html?id=79029
506 The giflib API Imager uses doesn't have a mechanism to set the
507 header version in 5.0.0.
508
509 - update the GIF library probe code to check for the new giflib 5.0.1
510 EGifSetGifVersion() function, and to check for the giflib 4.2.0
511 uninitialized gif89 bug.
512 https://rt.cpan.org/Ticket/Display.html?id=79679
513 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
514
515 - avoid static variables when capturing IPTC data from JPEG files
516
517 - match Imager::Font;:T1's error message translations to those from
518 later versions of T1Lib.
519
520 - for libtiff versions that support extended warning handlers (3.8.0
521 or later), use them to avoid some global variables.
522
523 - note Image::ExifTool for better metadata support.

ef84bb32 540Bug fixes:
38742a13 541
289d65f4
TC
542 - The size of rotated images is no longer rounded up so aggressively.
543 Added rounding to the linear interpolation done for rotate() and
544 matrix_transform() for 1 and 3 channel 8-bit images.
545 Adjusted the two tranlate matrices used to build the final rotation
546 matrix to use the distance between the outlier pixels rather than
547 the pixel dimensions (ie. dimension-1).
548 With all of this the output of rotate(degrees => 270) on an 8-bit
549 image exactly matches the output of rotate(right => 270).
550 https://rt.cpan.org/Ticket/Display.html?id=77063
551
ef84bb32
TC
552Other changes:
553
554 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
555 internals, those names only matter for the XS interface.
556
557 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
558 the API level compiled into a loadable module such as
559 Imager::File::GIF doesn't match that of Imager. Previously it
560 could be difficult to determine exactly which module was failing to
561 load.
562 https://rt.cpan.org/Ticket/Display.html?id=77173
563
564 - added Imager->check_file_limits() as an interface to the
565 i_int_check_image_file_limits() API.
566
567 - Imager->set_file_limits(reset => 1) now resets the limits to the
568 defaults rather than setting them all to unlimited.
569
570 - wrote a brief security note as Imager::Security
571 https://rt.cpan.org/Ticket/Display.html?id=68910

6f31dd14 573Imager 0.90 - 30 Apr 2012
7c4464f5
TC
574===========
575
576Bug fixes:
577
578 - Imager::Test::is_imaged() attempted to process an "epsilon"
579 parameter but the prototype didn't allow for the extra parameter.
580 Corrected the prototype.
581
29b38678
TC
582 - when downconverting samples (eg. from floating point to 8 bit)
583 Imager now rounds the sample value rather than attempting to
584 allocate input values over output values equally. The old
585 behaviour had the probably surprising effect of converting a
586 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
587 2.
588 This may result in slightly different 8 or 16-bit output images.
589
e2a86bac
TC
590 - BI_BITFIELD BMP images were handled incorrectly, both in
591 incorrectly calculating the space required for the masks and in
592 processing the image data itself.
593 https://rt.cpan.org/Ticket/Display.html?id=76736
594
595 - some odd width BMP BI_RLE4 images use run lengths that run one off
596 the edge of the image. Imager now allows this, discarding the
597 extra column.
598
599 - odd length RLE4 runs in BMP images were decoded incorrectly.

TC
601 - pkg-config could sometimes return a library that was in a directory
602 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
603 If no -L is included in the pkg-config library information check if
604 EU::MM can find the library, and if not, search our configured
605 directories and insert that into the library flags.
606 https://rt.cpan.org/Ticket/Display.html?id=75869
607
de50f459
TC
608 - Imager::Probe can now probe for libraries with dependent libraries,
609 common for static linking, eg. libpng requires libz.
610 https://rt.cpan.org/Ticket/Display.html?id=74043
611
612 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
613
614 - added alternative probe configurations that try to link libz, to
615 handle a statically linked libpng.
616 https://rt.cpan.org/Ticket/Display.html?id=74043
617
618 - if a probe includes testcode, Imager::Probe now checks that code as
619 part of the process of checking each configuration rather than as a
620 post test of the found configuration. This allows alternate
621 configurations to be checked if a matching but non-working
622 configuration is found.
623 https://rt.cpan.org/Ticket/Display.html?id=74043

TC
625Other changes:

627 - when reading or writing images via callbacks, the default callbacks
628 now push an error message indicating that a required callback was
629 called but not supplied.
630 https://rt.cpan.org/Ticket/Display.html?id=76782
631
632 - clarify which callbacks are required for reading and writing TIFF
633 images.
634
635 - improve logging for creation of callback I/O layers.
636

TC
637 - a little more documentation for Imager::Probe.

642 - PNG rework
643 - improve error reporting
644 - add png_interlace, png_bits tags
645 - read paletted images as paletted images, including transparency
646 - read 1 bit greyscale images as a type suitable for other file
647 handlers to write as bilevel
648 - read 16 bit/sample PNG as 16-bit/sample Imager images
649 - write "bilevel" paletted images as 1 bit grayscale images
650 - write paletted images as paletted images
651 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
652 images

a5919365
TC
671 - Imager (and the bundled dynamic modules) no longer fallback to
672 using DynaLoader if loading via XSLoader fails.
673 For the bundled modules this could hide useful error messages.
674 https://rt.cpan.org/Ticket/Display.html?id=75560

696 in MMOne.pfb is a Debian package.
697
02323e69
TC
698 - setsamples() is now a true complement to getsamples() - it can
699 write 8-bit or floating point samples from a scalar or array
700 reference. This adds i_psamp() and i_psampf() to the C level API.
701
702 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
703 changed to make better use of the typemap, but these aren't part of
704 the perl level API anyway. There were no changes to the C level
705 interfaces to these functions.
706
2a27eeff
TC
707 - getpixel() and setpixel() now accept a mix of scalar and array
708 references for the x and y parameters, and unequal array lengths is
709 no longer an error.

TC
860 - io_glue I/O buffering re-work:
861
862 - reorganize io_glue to do it's own buffering by default
863
864 - the unbuffered functions are available as i_io_raw_read() (or
865 raw_read() from perl) etc but are not recommended for typical
866 use.
867
868 - use the new i_io_peekn() when checking for file magic to avoid
869 seek, allowing Imager to detect the file type and read the file
870 from an unseekable stream (for formats that don't use random
871 access)
872
873 - added several new I/O layer API functions.
874
875 - fix the TGA performance problem, most noticably on Win32
876 https://rt.cpan.org/Ticket/Display.html?id=70037
877
878 - TIFF now uses wrapper functions of the correct types to avoid casts
879 https://rt.cpan.org/Ticket/Display.html?id=69912
880
881 - the callback IO object did its own buffering, controlled by the
882 maxbuffer parameter supplied to the read() and write() methods.
883 This buffering has been removed, to avoid redundancy with the
884 common io_glue buffering. This also avoids a bug in that code
885 which could rarely pass a zero length to the read callback and
886 then panic about the result.
887
888 - the callback IO object now tests the result of calling the close
889 callback, which should return true for success.
890
891 - the PNM reader did its own buffering. This buffering has been
892 removed to avoid redundancy with the common io_glue buffering.
893
894 - previously the read handlers for fd and callback I/O layers would
895 call the underlying interface (POSIX read or your supplied callback)
896 until it filled the buffer. It now only makes one call.
897
898 - added public constructors for I/O layer objects (see Imager::IO)
899
900 - all core file handlers now use the i_io_foo() wrappers to gain
901 access to buffered I/O rather than calling the I/O layer
902 callbacks directly.
903
904 - all core file handlers now check for error on close.
905
906 - Backward compatibility: if you hava custom file handlers, you can
907 use i_io_write() etc since they're available as macros in older
908 versions of Imager.
909
910 - eliminate the final remnants of io_glue_commit_types().
911
912 - bump IMAGER_API_VERSION, since the above may break assumptions.
913
914 - removed the long unused i_gen_reader() and i_gen_writer() utility
915 functions.

TC
918===========

0c647c9a
TC
920The main changes in the release versus 0.84 are:
921
922 - on 64-bit systems, 64-bit types are consistently used for image
923 dimensions and co-ordinated, and for memory block sizes.
924
925 - handle IFD loops in TIFF files correctly. Previously this would
926 lead to an infinite loop.

975Imager 0.84_01 - 8 Aug 2011
976==============
977
978Development release as a sanity check for the types re-work.
8d14daab
TC
979
980Massive types re-work:
981
982 - the type used internally for pixel co-ordinates and image sizes is
983 now 64-bit on 64-bit platforms (at least sane ones).
984
985 - size_t is now used consistently for memory block sizes.
986
987 - since this changes the binary interface, the Imager API version has
988 been incremented. Any module that uses the API will need to be
989 rebuilt. In most cases that will be enough, but calls to any APIs
990 that take a pointer to image sizes may need source changes.
991
992 - you should be able to create very large images on 64-bit systems,
993 if you have enough memory. Successfully created a 32768 x 49192 x
994 3 channel image, filled with a tiled image and scaled it. The
995 unscaled image was also successfully saved to a JPEG.
996
997 - check the image size before attempting to write BMP, GIF, JPEG,
998 PNG, SGI, TGA, TIFF images.
999
1000 - correctly handle reading TGA images over 32767 pixels wide or tall.
1001
1002Incidental changes:
1003
1004 - the gif_left and gif_top tags are now clamped to non-negative
1005 values when writing a GIF image.
1006
1007 - removed dead callback read/write code
1008
1009The default maximum memory size when reading files is now 1G.

1335 - added the ability to read multiple-image PNM files.
1336 Note that unlike the pbm/pgm/ppm specification this accepts mixed

1656 - moved the imtoc.perl code into Imager::Preprocess

1661 noalpha channels or back.
1662 https://rt.cpan.org/Ticket/Display.html?id=30908
1663
1664 - rubthrough() now falls back to pasting when the source doesn't have
1665 an alpha channel. This effectively treats the source as having a
1666 max alpha channel, the right thing to do.
1667 http://rt.cpan.org/Ticket/Display.html?id=29944

1672 Rewrote most of the combine modes to match the way the SVG draft
1673 defines them with respect to a translucent source and destination.

1718 problem with loading such an image. I haven't been able to find any
1719 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1720 I'll match it's behaviour. See issue 114913 in the GIMP's

2039Imager 0.55 - 16 Dec 2006
2040===========
2041
2042This is primarily a bug fix release.
2043
2044Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2045
2046There is one new feature:
2047
2048 - the Win32 font driver now supports UTF8 (RT 22166)
2049 http://www.cpanforum.com/threads/3276
2050 http://rt.cpan.org/Ticket/Display.html?id=22166
2051
2052Several bugs were fixed:
2053
2054 - the string() method would not output the string "0"
2055 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2056
2057 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2058 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2059
2060 - the gif_disposal and gif_user_input tags weren't being read from
2061 the file correctly
2062 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2063
2064 - gif.c was failing to build under MSVC
2065 http://rt.cpan.org/Ticket/Display.html?id=23922
2066
2067 - in some cases strings passed to the string() method were treated as
2068 terminated by NUL (chr 0)
2069 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2070
2071 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2072 that's the default build name for zlib on Win32.
2073 http://rt.cpan.org/Ticket/Display.html?id=23064
2074
2075 - search $Config{incpath} for headers too, which we should have been
2076 doing all along.
2077
2078Win32 font driver fixes:
2079
2080 - the global descent value from bounding box was the wrong sign
2081 http://www.cpanforum.com/threads/3276
2082
2083 - if the first or last glyph overflowed the left or right side of the
2084 advance width they would be clipped
2085
2086
2087Imager 0.54 - 14 Sep 2006
2088===========
2089
2090This is primarily a feature release:
2091
2092 - a new qtype value 'mixing' has been added to the scale()
2093 method. This is faster than 'normal', slower than 'preview'. This
2094 is based on the method used by pnmscale, and seems to produce less
2095 blurry results than normal.
2096 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2097
2098 - the rubthrough() method can now render onto images with an alpha
2099 channel.
2100 http://rt.cpan.org/Ticket/Display.html?id=20678
2101
2102 - the read_multi() method now falls back to calling doing a single
2103 image read via the read() method and write_multi() will now fall
2104 back to calling write() if a single image is supplied. This means
2105 you can simply call the read_multi() or write_multi() functions
2106 without having to check if the type is formatted by that method.
2107 http://rt.cpan.org/Ticket/Display.html?id=19457
2108 http://rt.cpan.org/Ticket/Display.html?id=19458
2109
2110 - the GIF loop extension can now be written. If you don't have
2111 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2112 should upgrade.
2113 http://rt.cpan.org/Ticket/Display.html?id=21185
2114
2115 - getscanline() and setscanline() can now read/write palette index
2116 based data from/to the image for paletted images, by setting type to
2117 'index'.
2118 http://rt.cpan.org/Ticket/Display.html?id=20338
2119
2120 - we no longer hassle you to disable GIF support
2121 http://rt.cpan.org/Ticket/Display.html?id=20687
2122
2123 - minor documentation fixes
2124
2125
2126Imager 0.53 - 26 Jul 2006
2127===========
2128
2129This is a bugfix release.
2130
2131Some test code was left in a code path not covered by the test
2132suite. A test was added to cover this code path and the test code was
2133removed.

2136
2137Imager 0.52 - 25 Jul 2006
2138===========
2139
2140This is primarily a feature release, but contains a fair few bug
2141fixes, new features:
2142
2143 - ability to read and write MS Windows ICO and CUR files
2144
2145 - you can now add file format plugins to support new file formats
2146
2147 - add POD coverage tests
2148
2149 - setcolors() and addcolors() now accept color names and so on
2150 instead of requiring Imager::Color objects.
2151 http://rt.cpan.org/Ticket/Display.html?id=20056
2152
2153 - flood_fill() can now fill to a specified border color instead of
2154 just to the area the same color as the seed.
2155 http://rt.cpan.org/Ticket/Display.html?id=19618
2156
2157
2158Bug fixes:
2159
2160 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2161 calculating the advance width.
2162 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2163
2164 - bounding_box for the T1 driver wasn't including leading and
2165 trailing spaces in the bounding box as the other drivers did, it also
2166 produced strange results for empty strings or strings containing only
2167 spaces
2168
2169 - when reading CMYK jpeg images they were being transferred to the
2170 image object as is, producing a four channel image. It only looked ok
2171 due to an old still unfixed Photoshop bug. We now convert from the
2172 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2173 http://rt.cpan.org/Ticket/Display.html?id=20416
2174
2175 - reading a CYMK TIFF would result in a 4 channel image, reading any
2176 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2177 result in an error.
2178 http://rt.cpan.org/Ticket/Display.html?id=20415
2179
2180 - added /usr/local/include to the default include search path, since
2181 we were already searching /usr/local/lib for libraries.
2182
2183And various minor fixes and documentation updates.
2184
2185
2186Imager 0.51 - 23 Apr 2006
