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

8Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
9================
10
08914ed1
TC
11 - re-work the t/200-file/400-basic.t to correctly handle failures
12 It's custom ok() function didn't have a prototype and didn't use scalar().
13 This caused ok() to use the note instead of the value being tested when
14 the method called returned an empty list. For an example of the problem
e6226ce5 15 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 16

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

91Imager 1.003 - 12 May 2015
92============
93
0fda3cfd
TC
94 - update 1.002 release notes to include the center change for filled
95 circle drawing.
96
97 - flood_fill() would escape beyond a 4-connected space under some
98 circumstances.
99 Added many more flood_fill() tests.

102Imager 1.002 - 3 Apr 2015
103============
104
334b8922
TC
105 - drawing anti-aliased filled circles is now 10 to 50 times faster
106 depending on the size of the circle.
0fda3cfd
TC
107 This also changed the center from being the center of the pixel to
108 being the top left of the pixel to match the filled arcs drawn by
109 arc().

TC
110 https://rt.cpan.org/Ticket/Display.html?id=101682
111
112 - enhancements to polygon filling:
113
114 - added a mode parameter to control how overlapping regions behave
115
116 - added a polypolygon() method to fill more than one polygon at a
117 time
118
119 - polygon filling is now exposed through the API.
120
45c8e262
TC
121 - added colormodel(), alphachannel() and colorchannels() methods.
122 These were added for two reasons:
123
124 - a future version of Imager may allow the number of channels in
125 an image to not directly represent the color model of an image.
126 eg. a greyscale TIFF image with multiple alpha channels.
127
128 - a future version of Imager may allow an image to be read without
129 translation, for example a TIFF file that contains measurements
0fda3cfd 130 from an instrument. Currently Imager transforms the samples into
45c8e262
TC
131 the range 0.0 ... 1.0 which may means the user has to translates
132 the value back.
133
134 An untranslated image would be unusable as image data, so
135 colormodel() would return "unknown" in this case.
136
137 Similarly a CMYK image might be returned as an "unknown" color
138 model image, if the caller chooses to disable translation to
139 RGB.

180==============
181
5dab5b9a
TC
182 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
183 the blue channel in the generated palette, and allow each color
184 component to be in the range 100..255 instead of just 100..254.
185 Thanks to Ralf Neubauer.
186 https://rt.cpan.org/Ticket/Display.html?id=97086
187
188 - revert "improved the XS for i_io_read() and i_io_raw_read()"
189 This caused problems with older perls and didn't provide much of a
190 performance improvement.
191
5bf25bc2 192 - support Inline 0.57 and later.
6d47a6af 193 Inline 0.57 changed the "with" interface.

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

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

216Imager 0.99 - 25 Jun 2014
217===========
218
dce1523b
TC
219 - Imager::IO->new_buffer() (and hence Imager->read()'s data
220 parameter) now accepts a reference to a scalar as well as just a
221 plain scalar.
6a160bce 222 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
223
224 - Imager::IO->new_buffer() now always makes a copy of the passed in
225 buffer to avoid problems with temporary objects used for the return
226 value of SvPVbyte().
6a160bce 227 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 228

229 - improved the XS for i_io_read() and i_io_raw_read()
230 https://rt.cpan.org/Ticket/Display.html?id=92738
231
232 - load plugins from absolute paths on Android
233 Thanks to Brian Fraser.
234 https://rt.cpan.org/Ticket/Display.html?id=93272
235
6a160bce
TC
236 - added the jpeg_optimize parameter for writing JPEG files. This can
237 significantly reduce file sizes, but uses more memory and time.
238 https://rt.cpan.org/Ticket/Display.html?id=94292
239
14fd9e5d
TC
240 - the autolevels filter now works on the luminosity of the image
241 rather then working per channel. The old autolevels filter is
242 still available as "autolevels_skew".
243 https://rt.cpan.org/Ticket/Display.html?id=94413
244
75d54149
TC
245 - Imager::File::PNG now supports libpng 1.6.10.
246 1.6.10 changed CRC errors from benign errors to normal errors,
247 which broke the test which used CRC errors to check for benign
248 error support. Switched to using a 1-bit grey-scale image with a
249 palette to test for benign errors.

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

f84f86a2
TC
295 - a documentation typo fix in Imager::Transformations
296 Thanks to Adrian Yee.
297 https://rt.cpan.org/Ticket/Display.html?id=88598
298
0179ecd6
TC
299 - Image::Probe, Imager's internal module for probing library
300 locations now searches the directories specified by LD_RUN_PATH,
301 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
302 and the corresponing s/\blib$/include/ directories for header
303 files.

314 - PNG: treat a version mismatch between headers and library as a
315 probe failure.

317
8e90f677
TC
318 - PNG: the check for benign error support is more complex than a
319 simple library version check, check for the appropriate macro.
320 Thanks for Slaven Rezic for following up on my CPAN Testers result
321 queries.

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

237d9e03 347 - Imager::Color's rgba() method now returns its values as integers
face45e7
TC
348 instead of floating point. (IV instead of NV).
349
19e9591b
TC
350 - The XS for i_map() and i_matrix_transform() now use the AV *
351 typemap instead of rolling their own.
352

TC
353 - The XS for DSO_call() now uses the HV * typemap instead of

0aaa8b4d
TC
356 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
357 i_gradgen() now use a new T_AVARRAY typemap that greatly
358 simplifies the XS code.
face45e7 359
ccd01d49

360 - many other minor XS changes
361
face45e7 362 - some XS code formatting

TC
384 - rearrange Imager's test files.
385 https://rt.cpan.org/Ticket/Display.html?id=84596
386
387 - Imager::Probe::_gcc_lib_paths now forces C locale.
388 A sufficiently recent gcc prints localized keys for the search
389 paths, which avoids that localization.
390 https://rt.cpan.org/Ticket/Display.html?id=84963
391
392 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
393 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
394 and true.
395 https://rt.cpan.org/Ticket/Display.html?id=85262

411Imager 0.95 - 19 Apr 2013
412===========
413
0a2956ab
TC
414 - handle the SVf_UTF8 flag correctly on magic strings passed to
415 Imager::IO's write() and raw_write() methods.
416 This may misbehave in perl 5.6.x since the UTF8 flag may not be
417 visible in the main SV after SvGETMAGIC().

427 - enable debug logging for the standard font tests
428
429 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
430 due to a bug in that version of perl.
431
432 - don't test for read() failing on a write-only handle in 5.8.x and
433 earlier, this was fixed in change 862083f7e4 in perl.
434
435 - report the version of Inline found during testing (an attempt to
436 diagnose some intermittent failures.)

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

549Enhancements:
550
551 - support for giflib 5.0. (5.0.1 and later)
552 https://rt.cpan.org/Ticket/Display.html?id=79029
553 The giflib API Imager uses doesn't have a mechanism to set the
554 header version in 5.0.0.
555
556 - update the GIF library probe code to check for the new giflib 5.0.1
557 EGifSetGifVersion() function, and to check for the giflib 4.2.0
558 uninitialized gif89 bug.
559 https://rt.cpan.org/Ticket/Display.html?id=79679
560 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
561
562 - avoid static variables when capturing IPTC data from JPEG files
563
564 - match Imager::Font;:T1's error message translations to those from
565 later versions of T1Lib.
566
567 - for libtiff versions that support extended warning handlers (3.8.0
568 or later), use them to avoid some global variables.

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

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

676 called but not supplied.

680 images.

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

TC
904
905 - add simple tests for the Imager::Test test_image generators
906
6d5c85a2
TC
907 - io_glue I/O buffering re-work:
908
909 - reorganize io_glue to do it's own buffering by default
910
911 - the unbuffered functions are available as i_io_raw_read() (or
912 raw_read() from perl) etc but are not recommended for typical
913 use.
914
915 - use the new i_io_peekn() when checking for file magic to avoid
916 seek, allowing Imager to detect the file type and read the file
917 from an unseekable stream (for formats that don't use random
918 access)
919
920 - added several new I/O layer API functions.
921
922 - fix the TGA performance problem, most noticably on Win32
923 https://rt.cpan.org/Ticket/Display.html?id=70037
924
925 - TIFF now uses wrapper functions of the correct types to avoid casts
926 https://rt.cpan.org/Ticket/Display.html?id=69912
927
928 - the callback IO object did its own buffering, controlled by the
929 maxbuffer parameter supplied to the read() and write() methods.
930 This buffering has been removed, to avoid redundancy with the
931 common io_glue buffering. This also avoids a bug in that code
932 which could rarely pass a zero length to the read callback and
933 then panic about the result.
934
935 - the callback IO object now tests the result of calling the close
936 callback, which should return true for success.
937
938 - the PNM reader did its own buffering. This buffering has been
939 removed to avoid redundancy with the common io_glue buffering.
940
941 - previously the read handlers for fd and callback I/O layers would
942 call the underlying interface (POSIX read or your supplied callback)
943 until it filled the buffer. It now only makes one call.
944
945 - added public constructors for I/O layer objects (see Imager::IO)
946
947 - all core file handlers now use the i_io_foo() wrappers to gain
948 access to buffered I/O rather than calling the I/O layer
949 callbacks directly.
950
951 - all core file handlers now check for error on close.
952
953 - Backward compatibility: if you hava custom file handlers, you can
954 use i_io_write() etc since they're available as macros in older
955 versions of Imager.
956
957 - eliminate the final remnants of io_glue_commit_types().
958
959 - bump IMAGER_API_VERSION, since the above may break assumptions.
960
961 - removed the long unused i_gen_reader() and i_gen_writer() utility
962 functions.

1024
1025Development release as a sanity check for the types re-work.
8d14daab
TC
1026
1027Massive types re-work:
1028
1029 - the type used internally for pixel co-ordinates and image sizes is
1030 now 64-bit on 64-bit platforms (at least sane ones).
1031
1032 - size_t is now used consistently for memory block sizes.
1033
1034 - since this changes the binary interface, the Imager API version has
1035 been incremented. Any module that uses the API will need to be
1036 rebuilt. In most cases that will be enough, but calls to any APIs
1037 that take a pointer to image sizes may need source changes.
1038
1039 - you should be able to create very large images on 64-bit systems,
1040 if you have enough memory. Successfully created a 32768 x 49192 x
1041 3 channel image, filled with a tiled image and scaled it. The
1042 unscaled image was also successfully saved to a JPEG.
1043
1044 - check the image size before attempting to write BMP, GIF, JPEG,
1045 PNG, SGI, TGA, TIFF images.
1046
1047 - correctly handle reading TGA images over 32767 pixels wide or tall.
1048
1049Incidental changes:
1050
1051 - the gif_left and gif_top tags are now clamped to non-negative
1052 values when writing a GIF image.
1053
1054 - removed dead callback read/write code
1055
1056The default maximum memory size when reading files is now 1G.

1762 - handling of the left-over bit for 16-bit/pixel TGA images has been
1763 changed to match the behaviour of the GIMP. Previously the bit
1764 being set was treated as an opaque pixel, but one user reported a
1765 problem with loading such an image. I haven't been able to find any
1766 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1767 I'll match it's behaviour. See issue 114913 in the GIMP's
1768 bugzilla.

1778 - the old dynaload code used Mach API functions to load dynamic
1779 libraries on Mac OS X. These APIs have been deprecated in OS X
1780 10.5 and were causing some build problems.
1781 So henceforth Imager uses the dlopen() family of functions, and you
1782 will need version 10.3 or later of OS X.

2089This is primarily a bug fix release.
2090
2091Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2092
2093There is one new feature:
2094
2095 - the Win32 font driver now supports UTF8 (RT 22166)
2096 http://www.cpanforum.com/threads/3276
2097 http://rt.cpan.org/Ticket/Display.html?id=22166
2098
2099Several bugs were fixed:
2100
2101 - the string() method would not output the string "0"
2102 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2103
2104 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2105 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2106
2107 - the gif_disposal and gif_user_input tags weren't being read from
2108 the file correctly
2109 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2110
2111 - gif.c was failing to build under MSVC
2112 http://rt.cpan.org/Ticket/Display.html?id=23922
2113
2114 - in some cases strings passed to the string() method were treated as
2115 terminated by NUL (chr 0)
2116 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2117
2118 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2119 that's the default build name for zlib on Win32.
2120 http://rt.cpan.org/Ticket/Display.html?id=23064
2121
2122 - search $Config{incpath} for headers too, which we should have been
2123 doing all along.
2124
2125Win32 font driver fixes:
2126
2127 - the global descent value from bounding box was the wrong sign
2128 http://www.cpanforum.com/threads/3276
2129
2130 - if the first or last glyph overflowed the left or right side of the
2131 advance width they would be clipped

2133
2134Imager 0.54 - 14 Sep 2006
2135===========
2136
2137This is primarily a feature release:
2138
2139 - a new qtype value 'mixing' has been added to the scale()
2140 method. This is faster than 'normal', slower than 'preview'. This
2141 is based on the method used by pnmscale, and seems to produce less
2142 blurry results than normal.
2143 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2144
2145 - the rubthrough() method can now render onto images with an alpha
2146 channel.
2147 http://rt.cpan.org/Ticket/Display.html?id=20678
2148
2149 - the read_multi() method now falls back to calling doing a single
2150 image read via the read() method and write_multi() will now fall
2151 back to calling write() if a single image is supplied. This means
2152 you can simply call the read_multi() or write_multi() functions
2153 without having to check if the type is formatted by that method.
2154 http://rt.cpan.org/Ticket/Display.html?id=19457
2155 http://rt.cpan.org/Ticket/Display.html?id=19458
2156
2157 - the GIF loop extension can now be written. If you don't have
2158 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2159 should upgrade.
2160 http://rt.cpan.org/Ticket/Display.html?id=21185
2161
2162 - getscanline() and setscanline() can now read/write palette index
2163 based data from/to the image for paletted images, by setting type to
2164 'index'.
2165 http://rt.cpan.org/Ticket/Display.html?id=20338
2166
2167 - we no longer hassle you to disable GIF support
2168 http://rt.cpan.org/Ticket/Display.html?id=20687
2169
2170 - minor documentation fixes
2171
2172
2173Imager 0.53 - 26 Jul 2006
2174===========
2175
2176This is a bugfix release.
2177
2178Some test code was left in a code path not covered by the test
2179suite. A test was added to cover this code path and the test code was
2180removed.

2192 - you can now add file format plugins to support new file formats
2193
2194 - add POD coverage tests
2195

2197 instead of requiring Imager::Color objects.
2198 http://rt.cpan.org/Ticket/Display.html?id=20056
2199

2204
2205Bug fixes:
2206
2207 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2208 calculating the advance width.
2209 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2210
2211 - bounding_box for the T1 driver wasn't including leading and
2212 trailing spaces in the bounding box as the other drivers did, it also
2213 produced strange results for empty strings or strings containing only
2214 spaces
2215
2216 - when reading CMYK jpeg images they were being transferred to the
2217 image object as is, producing a four channel image. It only looked ok
2218 due to an old still unfixed Photoshop bug. We now convert from the
2219 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2220 http://rt.cpan.org/Ticket/Display.html?id=20416
2221
2222 - reading a CYMK TIFF would result in a 4 channel image, reading any
2223 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2224 result in an error.
2225 http://rt.cpan.org/Ticket/Display.html?id=20415
2226
2227 - added /usr/local/include to the default include search path, since
2228 we were already searching /usr/local/lib for libraries.
2229
