TC
3Coverity finally finished a build, fix a few problems:
4
5 - reading a color-mapped TGA file with an id string would cause a
6 double-free if the palette was truncated.
7
6494c395
TC
8 - mixing scaling to sizes where the accumulator row, the working
9 output row or the working input row didn't fit into the address
10 space could result in memory leaks. This can probably only be
11 reproduced on very wide floating-point sample images.
12
fc24ca5f 13 - convert an array style function parameter pointer to pointer style
3d7b055c
TC
14 to prevent confusing Coverity in the T1 bounding box implementation.
15
16 - Similarly in the FT1 bounding box implementation.
fc24ca5f
TC
17
18 - initialize a pointer to prevent Coverity complaining in polygon
19 drawing (it should always end up being set.)
20
f7675b46
TC
21 - addi style makemap could potentially read one past the end of an
22 array.
23
58ec1fde
TC
24 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
25 would result in read beyond the end of the built-in hatch array.
26 Negative values (which Coverity didn't complain about) could also
27 cause problems.
28
b7346865
TC
29 - the Imager::Color set_internal() interal method no longer
30 calls the over-complicated ICL_set_internal() (which is retained
31 only for the old API.) Coverity complained that this leaked, but
32 this could only occur with an invalid (NULL pointer) color object.
33
785364c1
TC
34 - the underlying implementation of the map() method could read before
35 the beginning on an allocated array if supplied with inconsistent
36 parameters, which Coverity complained about. No Imager code calls
37 that function with inconsistent parameters, but a
38 belt-and-suspenders check was added.

40Imager 1.008 - 31 Dec 2018
41============
42
75e155e1 43 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
44 This allows file formats that store EXIF data as blobs similarly
45 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 46
b5bbf161 47 - added some more file extensions to image file type mappings
75e155e1
TC
48

68 - the internal i_errors() function now correctly allocates the stack
69 space needed for its result.
70 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
71
72 - t/100-base/020-color.t now uses Imager::Test's test functions
73 instead of its own.
74 https://rt.cpan.org/Ticket/Display.html?id=111993
75
344dda51
TC
76 - write_multi() now returns an error result (a false value) if called
77 with a non-(Imager image object). Previously it would typically
78 crash.
79 https://rt.cpan.org/Ticket/Display.html?id=117878
80
81 - improve the documentation of the jpegquality parameter when
82 writing JPEG files.
83
84 - add code to mitigate CVE-2016-1238, Imager will no longer search the
85 default current directory entry in @INC when searching for file
86 format support modules.

115
735b3e7b
TC
116 - don't use the seek() method on opened() handles in
117 t/200-file/400-basic.t. In older versions of perl such handles are
118 only IO::Handle objects, not IO::File, and don't have a seek()
119 method.

121Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
122================
123
08914ed1
TC
124 - re-work the t/200-file/400-basic.t to correctly handle failures
125 It's custom ok() function didn't have a prototype and didn't use scalar().
126 This caused ok() to use the note instead of the value being tested when
127 the method called returned an empty list. For an example of the problem
e6226ce5 128 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 129
a2791e47
TC
130 - remove some noise from when Imager tried to work with bugs in old
131 versions of giflib. I can't do much about the new bugs.
08914ed1 132
e6226ce5
TC
133 - the new autolevels filter (Imager 0.99) used an integer for the
134 sample scaling factor which caused the top output level to be too
135 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
136 https://rt.cpan.org/Ticket/Display.html?id=111871
137
e6226ce5 138 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
139 minimum and maximum luminance from the histogram. This slightly
140 reduced the contrast of the output image.
141 https://rt.cpan.org/Ticket/Display.html?id=111871
142
143 - the new autolevels filter now uses a lookup table for 8-bit images
144 to avoid a floating point multiply for each sample.
145 https://rt.cpan.org/Ticket/Display.html?id=111871
146
e6226ce5
TC
147 - fixed several memory leaks detected by valgrind:
148
149 - addcolors() leaked the temporary array of colors supplied to the
150 internal API
151
152 - make_palette() leaked the temporary image array (not the images
153 themselves) passed to the internal API.
154
155 - combine()/i_combine() leaked its working row buffers
156
157 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
158 buffer if there were too many colors
159
160 - getcolorcount()/i_count_colors() leaked the sample buffer if
161 there were too many colors.
162
163 - the nearest_color filter (undocumented until I find a use for it)
164 leaked both temporaries passed to the API and internal buffers
165
a2791e47
TC
166 - the internal process of upgrading a paletted image to a direct
167 color image would leak a context object reference count.
168
169 - a write failure when writing to a GIF file could leak memory.
170
171 - failing to write to a 1-bit/pixel ICO image could leak memory.
172
173 - Imager no longer deliberately leaks the context object from the
174 initial thread. This was done to ensure there was always a context
175 object available, but the code that needed that now handles the
176 lack correctly,
177
e6226ce5
TC
178 - fixed some uninitialized memory usage detected by valgrind:
179
180 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
181 i_matrix_transform_bg() didn't initialize a working color value
182 if there was zero pixel coverage.
183
184 - i_ft2_cp() didn't initialize the complete color when producing an
185 intermediate image. This caused uninitialized value usage when
186 logging the color.

204Imager 1.003 - 12 May 2015
205============
206
0fda3cfd
TC
207 - update 1.002 release notes to include the center change for filled
208 circle drawing.
209
210 - flood_fill() would escape beyond a 4-connected space under some
211 circumstances.
212 Added many more flood_fill() tests.

TC
215Imager 1.002 - 3 Apr 2015
216============
217
334b8922
TC
218 - drawing anti-aliased filled circles is now 10 to 50 times faster
219 depending on the size of the circle.
0fda3cfd
TC
220 This also changed the center from being the center of the pixel to
221 being the top left of the pixel to match the filled arcs drawn by
222 arc().
334b8922
TC
223 https://rt.cpan.org/Ticket/Display.html?id=101682
224
225 - enhancements to polygon filling:
226
227 - added a mode parameter to control how overlapping regions behave
228
229 - added a polypolygon() method to fill more than one polygon at a
230 time
231
232 - polygon filling is now exposed through the API.
233
45c8e262
TC
234 - added colormodel(), alphachannel() and colorchannels() methods.
235 These were added for two reasons:
236
237 - a future version of Imager may allow the number of channels in
238 an image to not directly represent the color model of an image.
239 eg. a greyscale TIFF image with multiple alpha channels.
240
241 - a future version of Imager may allow an image to be read without
242 translation, for example a TIFF file that contains measurements
0fda3cfd 243 from an instrument. Currently Imager transforms the samples into
d96c4de8 244 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
245 the value back.
246
247 An untranslated image would be unusable as image data, so
248 colormodel() would return "unknown" in this case.
249
250 Similarly a CMYK image might be returned as an "unknown" color
251 model image, if the caller chooses to disable translation to
252 RGB.

TC
287 - fix the skip check for the iolayer qr// buffer test

293==============
294
5dab5b9a
TC
295 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
296 the blue channel in the generated palette, and allow each color
297 component to be in the range 100..255 instead of just 100..254.
298 Thanks to Ralf Neubauer.
299 https://rt.cpan.org/Ticket/Display.html?id=97086
300
301 - revert "improved the XS for i_io_read() and i_io_raw_read()"
302 This caused problems with older perls and didn't provide much of a
303 performance improvement.
304
5bf25bc2 305 - support Inline 0.57 and later.
6d47a6af 306 Inline 0.57 changed the "with" interface.

319
320 - GIF: avoid a double-free when do_write() fails.

330===========
331
dce1523b
TC
332 - Imager::IO->new_buffer() (and hence Imager->read()'s data
333 parameter) now accepts a reference to a scalar as well as just a
334 plain scalar.
6a160bce 335 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
336
337 - Imager::IO->new_buffer() now always makes a copy of the passed in
338 buffer to avoid problems with temporary objects used for the return
339 value of SvPVbyte().

344
345 - load plugins from absolute paths on Android
346 Thanks to Brian Fraser.
347 https://rt.cpan.org/Ticket/Display.html?id=93272
348
6a160bce
TC
349 - added the jpeg_optimize parameter for writing JPEG files. This can
350 significantly reduce file sizes, but uses more memory and time.
351 https://rt.cpan.org/Ticket/Display.html?id=94292
352
14fd9e5d
TC
353 - the autolevels filter now works on the luminosity of the image
354 rather then working per channel. The old autolevels filter is
355 still available as "autolevels_skew".
356 https://rt.cpan.org/Ticket/Display.html?id=94413
357
75d54149
TC
358 - Imager::File::PNG now supports libpng 1.6.10.
359 1.6.10 changed CRC errors from benign errors to normal errors,
360 which broke the test which used CRC errors to check for benign
361 error support. Switched to using a 1-bit grey-scale image with a
362 palette to test for benign errors.

365Imager 0.98 - 3 Jan 2014
366===========
367
f84f86a2
TC
368Incompatible changes:
369
370 - the return value of setpixel() has changed.
371
372 Previously the return values for undrawable pixels vs caller errors
373 changed depending on whether you used the multiple pixel calling
374 mechanism, or the single pixel mechanism.
375
376 Now:
377
378 - for an invalid parameter, such as an unknown colour, or missing
379 parameter, an empty list (or undef in scalar context) is
380 returned, and errstr() is set,
381
382 - otherwise the number of pixels drawn is returned. If none of
383 the pixels could be drawn (they were all outside the image), "0
384 but true" is returned.
385
386 https://rt.cpan.org/Ticket/Display.html?id=87650
387
388Other changes:
389
6ba09ab9
TC
390 - when drawing on an image with an alpha channel where the source
391 minimum is greater than zero, Imager would read from beyond the end
392 of a malloc() allocated buffer. In rare circumstances this could
393 lead to some of the source image not being written to the target
394 image, or possibly to a segmentation fault.
395 I don't believe this has any security concerns beyond that.
396
0d052fd9
TC
397 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
398 text drawn would be nonsense. This would also read beyond the end
399 of a malloced buffer.
400
13671b17
TC
401 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
402 truncated early.
403 https://rt.cpan.org/Ticket/Display.html?id=88993
404

0179ecd6
TC
412 - Image::Probe, Imager's internal module for probing library
413 locations now searches the directories specified by LD_RUN_PATH,
414 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
415 and the corresponing s/\blib$/include/ directories for header
416 files.

443 - TIFF: handle SampleFormat = 2 by translating the signed integer
444 values to unsigned by flipping their sign bits.
445
446 Handle SampleFormat = 3 where possible.
447
448 SampleFormat is ignored for paletted images.
449
237d9e03
TC
450 Mixed SampleFormat are handled incorrectly, since libtiff returns
451 only the first SampleFormat value, and an image with both an alpha
452 channel and SampleFormat = 2 for color channels probably has a
453 different SampleFormat for the alpha channel.

TC
702 - The size of rotated images is no longer rounded up so aggressively.
703 Added rounding to the linear interpolation done for rotate() and
704 matrix_transform() for 1 and 3 channel 8-bit images.
705 Adjusted the two tranlate matrices used to build the final rotation
706 matrix to use the distance between the outlier pixels rather than
707 the pixel dimensions (ie. dimension-1).
708 With all of this the output of rotate(degrees => 270) on an 8-bit
709 image exactly matches the output of rotate(right => 270).

711
ef84bb32
TC
712Other changes:
713
714 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
715 internals, those names only matter for the XS interface.
716
717 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
718 the API level compiled into a loadable module such as
719 Imager::File::GIF doesn't match that of Imager. Previously it
720 could be difficult to determine exactly which module was failing to
721 load.
722 https://rt.cpan.org/Ticket/Display.html?id=77173
723
724 - added Imager->check_file_limits() as an interface to the
725 i_int_check_image_file_limits() API.
726
727 - Imager->set_file_limits(reset => 1) now resets the limits to the
728 defaults rather than setting them all to unlimited.

736Bug fixes:

739 parameter but the prototype didn't allow for the extra parameter.
740 Corrected the prototype.
741
29b38678
TC
742 - when downconverting samples (eg. from floating point to 8 bit)
743 Imager now rounds the sample value rather than attempting to
744 allocate input values over output values equally. The old
745 behaviour had the probably surprising effect of converting a
746 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
747 2.
748 This may result in slightly different 8 or 16-bit output images.
749
e2a86bac
TC
750 - BI_BITFIELD BMP images were handled incorrectly, both in
751 incorrectly calculating the space required for the masks and in
752 processing the image data itself.
753 https://rt.cpan.org/Ticket/Display.html?id=76736
754
755 - some odd width BMP BI_RLE4 images use run lengths that run one off
756 the edge of the image. Imager now allows this, discarding the
757 extra column.
758
759 - odd length RLE4 runs in BMP images were decoded incorrectly.

TC
761 - pkg-config could sometimes return a library that was in a directory
762 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
763 If no -L is included in the pkg-config library information check if
764 EU::MM can find the library, and if not, search our configured
765 directories and insert that into the library flags.

768 - Imager::Probe can now probe for libraries with dependent libraries,
769 common for static linking, eg. libpng requires libz.
770 https://rt.cpan.org/Ticket/Display.html?id=74043
771
772 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
773
774 - added alternative probe configurations that try to link libz, to
775 handle a statically linked libpng.
776 https://rt.cpan.org/Ticket/Display.html?id=74043
777
778 - if a probe includes testcode, Imager::Probe now checks that code as
779 part of the process of checking each configuration rather than as a
780 post test of the found configuration. This allows alternate
781 configurations to be checked if a matching but non-working
782 configuration is found.

858 - setsamples() is now a true complement to getsamples() - it can
859 write 8-bit or floating point samples from a scalar or array
860 reference. This adds i_psamp() and i_psampf() to the C level API.
861
862 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have

1020 - io_glue I/O buffering re-work:
1021
1022 - reorganize io_glue to do it's own buffering by default
1023
1024 - the unbuffered functions are available as i_io_raw_read() (or
1025 raw_read() from perl) etc but are not recommended for typical
1026 use.
1027
1028 - use the new i_io_peekn() when checking for file magic to avoid
1029 seek, allowing Imager to detect the file type and read the file
1030 from an unseekable stream (for formats that don't use random
1031 access)
1032
1033 - added several new I/O layer API functions.
1034
1035 - fix the TGA performance problem, most noticably on Win32
1036 https://rt.cpan.org/Ticket/Display.html?id=70037
1037
1038 - TIFF now uses wrapper functions of the correct types to avoid casts
1039 https://rt.cpan.org/Ticket/Display.html?id=69912
1040
1041 - the callback IO object did its own buffering, controlled by the
1042 maxbuffer parameter supplied to the read() and write() methods.
1043 This buffering has been removed, to avoid redundancy with the
1044 common io_glue buffering. This also avoids a bug in that code
1045 which could rarely pass a zero length to the read callback and
1046 then panic about the result.
1047
1048 - the callback IO object now tests the result of calling the close
1049 callback, which should return true for success.
1050
1051 - the PNM reader did its own buffering. This buffering has been
1052 removed to avoid redundancy with the common io_glue buffering.
1053
1054 - previously the read handlers for fd and callback I/O layers would
1055 call the underlying interface (POSIX read or your supplied callback)
1056 until it filled the buffer. It now only makes one call.
1057
1058 - added public constructors for I/O layer objects (see Imager::IO)
1059
1060 - all core file handlers now use the i_io_foo() wrappers to gain
1061 access to buffered I/O rather than calling the I/O layer
1062 callbacks directly.
1063
1064 - all core file handlers now check for error on close.
1065
1066 - Backward compatibility: if you hava custom file handlers, you can
1067 use i_io_write() etc since they're available as macros in older
1068 versions of Imager.
1069
1070 - eliminate the final remnants of io_glue_commit_types().
1071
1072 - bump IMAGER_API_VERSION, since the above may break assumptions.
1073
1074 - removed the long unused i_gen_reader() and i_gen_writer() utility
1075 functions.

1138Development release as a sanity check for the types re-work.
8d14daab
TC
1139
1140Massive types re-work:
1141
1142 - the type used internally for pixel co-ordinates and image sizes is
1143 now 64-bit on 64-bit platforms (at least sane ones).
1144
1145 - size_t is now used consistently for memory block sizes.
1146
1147 - since this changes the binary interface, the Imager API version has
1148 been incremented. Any module that uses the API will need to be
1149 rebuilt. In most cases that will be enough, but calls to any APIs
1150 that take a pointer to image sizes may need source changes.
1151
1152 - you should be able to create very large images on 64-bit systems,
1153 if you have enough memory. Successfully created a 32768 x 49192 x
1154 3 channel image, filled with a tiled image and scaled it. The
1155 unscaled image was also successfully saved to a JPEG.
1156
1157 - check the image size before attempting to write BMP, GIF, JPEG,
1158 PNG, SGI, TGA, TIFF images.
1159
1160 - correctly handle reading TGA images over 32767 pixels wide or tall.
1161
1162Incidental changes:
1163
1164 - the gif_left and gif_top tags are now clamped to non-negative
1165 values when writing a GIF image.
1166
1167 - removed dead callback read/write code
1168
1169The default maximum memory size when reading files is now 1G.

e02d22d2
TC
1779 - Possible security issue: The floating point sample path for image
1780 based fills had a buffer overflow. This would overwrite the end of
1781 a malloc()ed buffer with double precision floats.

e02d22d2 1784

TC
1785 - check that the result of fileno($fh) is defined rather than simply
1786 true when read() or write() is supplied with an fh parameter.
1787 http://rt.cpan.org/Ticket/Display.html?id=35139
1788
1789 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1790 resulting in a SIGSEGV when attempting to scale an image to a size
1791 too large to fit in memory. This is a NULL pointer access issue,
1792 not a buffer overflow.
1793 Added a check for the failure.
1794 scale_calculate() (and hence scale()) will now fail if any of the
1795 scale size parameters are a reference.

1807This release primarily contains changes to improve ease of use -
1808rather than you having to convert images to the appropriate number of
1809channels, Imager handles it internally. How to handle drawing colors
1810and the default combine mode is a thornier problem left for some other
1811release.

TC
1816 - moved the imtoc.perl code into Imager::Preprocess
1817
1818 - paste() and rubthrough() now adapt the source image data to the
1819 destination, so you can now safely paste/rubthrough from greyscale
1820 images to color images or back, or from alpha channel images to
1821 noalpha channels or back.
1822 https://rt.cpan.org/Ticket/Display.html?id=30908
1823
1824 - rubthrough() now falls back to pasting when the source doesn't have
1825 an alpha channel. This effectively treats the source as having a
1826 max alpha channel, the right thing to do.
1827 http://rt.cpan.org/Ticket/Display.html?id=29944
1828
1829 - re-worked most of the area filling code to use a common set of
1830 functions when filling.
1831 Corrected normal combine mode.
1832 Rewrote most of the combine modes to match the way the SVG draft
1833 defines them with respect to a translucent source and destination.
1834 Added tests for translucent source and destination.
1835 Added tests to check 8-bit/sample and double/sample combines work
1836 similarly.

1860 - mixing qtype scaling now sets all channels of a pixel to zero if
1861 the pixel has zero coverage (zero alpha). This should produce more
1862 compressible output files.

1868 I'm not changing the #! lines of the sample code, since it's sample

1872 - some TGA images weren't being detected correctly as TGA images
1873 https://rt.cpan.org/Ticket/Display.html?id=32925
1874
1875 - handling of the left-over bit for 16-bit/pixel TGA images has been
1876 changed to match the behaviour of the GIMP. Previously the bit
1877 being set was treated as an opaque pixel, but one user reported a
1878 problem with loading such an image. I haven't been able to find any
1879 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1880 I'll match it's behaviour. See issue 114913 in the GIMP's
1881 bugzilla.

1891 - the old dynaload code used Mach API functions to load dynamic
1892 libraries on Mac OS X. These APIs have been deprecated in OS X
1893 10.5 and were causing some build problems.
1894 So henceforth Imager uses the dlopen() family of functions, and you
1895 will need version 10.3 or later of OS X.

2181
2182 - previously, reading ASCII PBM files required spaces between samples,
2183 even though the format doesn't require that

2187
2188 - force flushing of the output from i_tt_dump_names() and test output

2199Imager 0.55 - 16 Dec 2006
2200===========
2201
2202This is primarily a bug fix release.
2203
2204Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2205
2206There is one new feature:
2207
2208 - the Win32 font driver now supports UTF8 (RT 22166)
2209 http://www.cpanforum.com/threads/3276
2210 http://rt.cpan.org/Ticket/Display.html?id=22166
2211
2212Several bugs were fixed:
2213
2214 - the string() method would not output the string "0"
2215 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2216
2217 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2218 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2219
2220 - the gif_disposal and gif_user_input tags weren't being read from
2221 the file correctly
2222 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2223
2224 - gif.c was failing to build under MSVC
2225 http://rt.cpan.org/Ticket/Display.html?id=23922
2226
2227 - in some cases strings passed to the string() method were treated as
2228 terminated by NUL (chr 0)
2229 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2230
2231 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2232 that's the default build name for zlib on Win32.
2233 http://rt.cpan.org/Ticket/Display.html?id=23064
2234
2235 - search $Config{incpath} for headers too, which we should have been
2236 doing all along.
2237
2238Win32 font driver fixes:
2239
2240 - the global descent value from bounding box was the wrong sign
2241 http://www.cpanforum.com/threads/3276
2242
2243 - if the first or last glyph overflowed the left or right side of the
2244 advance width they would be clipped
2245
2246
2247Imager 0.54 - 14 Sep 2006
2248===========
2249
2250This is primarily a feature release:
2251
2252 - a new qtype value 'mixing' has been added to the scale()
2253 method. This is faster than 'normal', slower than 'preview'. This
2254 is based on the method used by pnmscale, and seems to produce less
2255 blurry results than normal.
2256 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2257
2258 - the rubthrough() method can now render onto images with an alpha
2259 channel.
2260 http://rt.cpan.org/Ticket/Display.html?id=20678
2261
2262 - the read_multi() method now falls back to calling doing a single
2263 image read via the read() method and write_multi() will now fall
2264 back to calling write() if a single image is supplied. This means
2265 you can simply call the read_multi() or write_multi() functions
2266 without having to check if the type is formatted by that method.
2267 http://rt.cpan.org/Ticket/Display.html?id=19457
2268 http://rt.cpan.org/Ticket/Display.html?id=19458
2269
2270 - the GIF loop extension can now be written. If you don't have
2271 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2272 should upgrade.
2273 http://rt.cpan.org/Ticket/Display.html?id=21185
2274
2275 - getscanline() and setscanline() can now read/write palette index
2276 based data from/to the image for paletted images, by setting type to
2277 'index'.
2278 http://rt.cpan.org/Ticket/Display.html?id=20338
2279
2280 - we no longer hassle you to disable GIF support
2281 http://rt.cpan.org/Ticket/Display.html?id=20687
2282
2283 - minor documentation fixes
2284
2285
2286Imager 0.53 - 26 Jul 2006
2287===========
2288
2289This is a bugfix release.
2290
2291Some test code was left in a code path not covered by the test
2292suite. A test was added to cover this code path and the test code was
2293removed.
2294http://rt.cpan.org/Public/Bug/Display.html?id=20705
2295
2296
2297Imager 0.52 - 25 Jul 2006
2298===========
2299
2300This is primarily a feature release, but contains a fair few bug
2301fixes, new features:
2302
2303 - ability to read and write MS Windows ICO and CUR files
2304
2305 - you can now add file format plugins to support new file formats
2306
2307 - add POD coverage tests
2308
2309 - setcolors() and addcolors() now accept color names and so on
2310 instead of requiring Imager::Color objects.
2311 http://rt.cpan.org/Ticket/Display.html?id=20056
2312
2313 - flood_fill() can now fill to a specified border color instead of
2314 just to the area the same color as the seed.
2315 http://rt.cpan.org/Ticket/Display.html?id=19618
2316
2317
2318Bug fixes:
2319
2320 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2321 calculating the advance width.
2322 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2323
2324 - bounding_box for the T1 driver wasn't including leading and
2325 trailing spaces in the bounding box as the other drivers did, it also
2326 produced strange results for empty strings or strings containing only
2327 spaces
2328
2329 - when reading CMYK jpeg images they were being transferred to the
2330 image object as is, producing a four channel image. It only looked ok
2331 due to an old still unfixed Photoshop bug. We now convert from the
2332 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2333 http://rt.cpan.org/Ticket/Display.html?id=20416
2334
2335 - reading a CYMK TIFF would result in a 4 channel image, reading any
2336 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2337 result in an error.
2338 http://rt.cpan.org/Ticket/Display.html?id=20415
2339
2340 - added /usr/local/include to the default include search path, since
2341 we were already searching /usr/local/lib for libraries.
2342
2343And various minor fixes and documentation updates.
2344
2345
2346Imager 0.51 - 23 Apr 2006

2350 a crash
2351 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2352
2353 - fix mis-processing of the src_maxx and src_maxy parameters of the
2354 paste() method
2355 http://rt.cpan.org/Public/Bug/Display.html?id=18712
2356
2357 - fix a problem in Imager's "smart" handling of the color parameter
2358 to various methods.
2359 http://rt.cpan.org/Public/Bug/Display.html?id=18561
2360
2361
2362Imager 0.50 - 29 Mar 2006
2363===========
2364

2366 or 4 channel image to jpeg or a 2 channel image to tga where the
2367 output is an in-memeory buffer.
2368 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2369
2370 - fixes an incorrect pointer parameter in the PNG code
2371 http://rt.cpan.org/Public/Bug/Display.html?id=18051
