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.

34Imager 1.008 - 31 Dec 2018
35============
36
75e155e1 37 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
38 This allows file formats that store EXIF data as blobs similarly
39 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 40
b5bbf161 41 - added some more file extensions to image file type mappings
75e155e1
TC
42
43 - added add_type_extensions() class method

62 - the internal i_errors() function now correctly allocates the stack
63 space needed for its result.
64 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
65
66 - t/100-base/020-color.t now uses Imager::Test's test functions
67 instead of its own.

69
344dda51
TC
70 - write_multi() now returns an error result (a false value) if called
71 with a non-(Imager image object). Previously it would typically
72 crash.
73 https://rt.cpan.org/Ticket/Display.html?id=117878
74
75 - improve the documentation of the jpegquality parameter when
76 writing JPEG files.
77
78 - add code to mitigate CVE-2016-1238, Imager will no longer search the
79 default current directory entry in @INC when searching for file
80 format support modules.

109
735b3e7b
TC
110 - don't use the seek() method on opened() handles in
111 t/200-file/400-basic.t. In older versions of perl such handles are
112 only IO::Handle objects, not IO::File, and don't have a seek()
113 method.

115Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
116================
117
08914ed1
TC
118 - re-work the t/200-file/400-basic.t to correctly handle failures
119 It's custom ok() function didn't have a prototype and didn't use scalar().
120 This caused ok() to use the note instead of the value being tested when
121 the method called returned an empty list. For an example of the problem
e6226ce5 122 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 123
a2791e47
TC
124 - remove some noise from when Imager tried to work with bugs in old
125 versions of giflib. I can't do much about the new bugs.
08914ed1 126
e6226ce5
TC
127 - the new autolevels filter (Imager 0.99) used an integer for the
128 sample scaling factor which caused the top output level to be too
129 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
130 https://rt.cpan.org/Ticket/Display.html?id=111871
131
e6226ce5 132 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
133 minimum and maximum luminance from the histogram. This slightly
134 reduced the contrast of the output image.
135 https://rt.cpan.org/Ticket/Display.html?id=111871
136
137 - the new autolevels filter now uses a lookup table for 8-bit images
138 to avoid a floating point multiply for each sample.
139 https://rt.cpan.org/Ticket/Display.html?id=111871
140
e6226ce5
TC
141 - fixed several memory leaks detected by valgrind:
142
143 - addcolors() leaked the temporary array of colors supplied to the
144 internal API
145
146 - make_palette() leaked the temporary image array (not the images
147 themselves) passed to the internal API.
148
149 - combine()/i_combine() leaked its working row buffers
150
151 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
152 buffer if there were too many colors
153
154 - getcolorcount()/i_count_colors() leaked the sample buffer if
155 there were too many colors.
156
157 - the nearest_color filter (undocumented until I find a use for it)
158 leaked both temporaries passed to the API and internal buffers
159
a2791e47
TC
160 - the internal process of upgrading a paletted image to a direct
161 color image would leak a context object reference count.
162
163 - a write failure when writing to a GIF file could leak memory.
164
165 - failing to write to a 1-bit/pixel ICO image could leak memory.
166
167 - Imager no longer deliberately leaks the context object from the
168 initial thread. This was done to ensure there was always a context
169 object available, but the code that needed that now handles the
170 lack correctly,
171
e6226ce5
TC
172 - fixed some uninitialized memory usage detected by valgrind:
173
174 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
175 i_matrix_transform_bg() didn't initialize a working color value
176 if there was zero pixel coverage.
177
178 - i_ft2_cp() didn't initialize the complete color when producing an
179 intermediate image. This caused uninitialized value usage when
180 logging the color.

200
0fda3cfd
TC
201 - update 1.002 release notes to include the center change for filled
202 circle drawing.
203
204 - flood_fill() would escape beyond a 4-connected space under some
205 circumstances.
206 Added many more flood_fill() tests.

TC
209Imager 1.002 - 3 Apr 2015
210============
211
334b8922
TC
212 - drawing anti-aliased filled circles is now 10 to 50 times faster
213 depending on the size of the circle.
0fda3cfd
TC
214 This also changed the center from being the center of the pixel to
215 being the top left of the pixel to match the filled arcs drawn by
216 arc().
334b8922
TC
217 https://rt.cpan.org/Ticket/Display.html?id=101682
218
219 - enhancements to polygon filling:
220
221 - added a mode parameter to control how overlapping regions behave
222
223 - added a polypolygon() method to fill more than one polygon at a
224 time
225
226 - polygon filling is now exposed through the API.
227
45c8e262
TC
228 - added colormodel(), alphachannel() and colorchannels() methods.
229 These were added for two reasons:
230
231 - a future version of Imager may allow the number of channels in
232 an image to not directly represent the color model of an image.
233 eg. a greyscale TIFF image with multiple alpha channels.
234
235 - a future version of Imager may allow an image to be read without
236 translation, for example a TIFF file that contains measurements
0fda3cfd 237 from an instrument. Currently Imager transforms the samples into
d96c4de8 238 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
239 the value back.
240
241 An untranslated image would be unusable as image data, so
242 colormodel() would return "unknown" in this case.
243
244 Similarly a CMYK image might be returned as an "unknown" color
245 model image, if the caller chooses to disable translation to
246 RGB.

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

287==============
288
5dab5b9a
TC
289 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
290 the blue channel in the generated palette, and allow each color
291 component to be in the range 100..255 instead of just 100..254.
292 Thanks to Ralf Neubauer.
293 https://rt.cpan.org/Ticket/Display.html?id=97086
294
295 - revert "improved the XS for i_io_read() and i_io_raw_read()"
296 This caused problems with older perls and didn't provide much of a
297 performance improvement.
298
5bf25bc2 299 - support Inline 0.57 and later.
6d47a6af 300 Inline 0.57 changed the "with" interface.

313
314 - GIF: avoid a double-free when do_write() fails.

324===========
325
dce1523b
TC
326 - Imager::IO->new_buffer() (and hence Imager->read()'s data
327 parameter) now accepts a reference to a scalar as well as just a
328 plain scalar.
6a160bce 329 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
330
331 - Imager::IO->new_buffer() now always makes a copy of the passed in
332 buffer to avoid problems with temporary objects used for the return
333 value of SvPVbyte().

340 Thanks to Brian Fraser.
341 https://rt.cpan.org/Ticket/Display.html?id=93272
342
6a160bce
TC
343 - added the jpeg_optimize parameter for writing JPEG files. This can
344 significantly reduce file sizes, but uses more memory and time.
345 https://rt.cpan.org/Ticket/Display.html?id=94292
346
14fd9e5d
TC
347 - the autolevels filter now works on the luminosity of the image
348 rather then working per channel. The old autolevels filter is
349 still available as "autolevels_skew".
350 https://rt.cpan.org/Ticket/Display.html?id=94413
351
75d54149
TC
352 - Imager::File::PNG now supports libpng 1.6.10.
353 1.6.10 changed CRC errors from benign errors to normal errors,
354 which broke the test which used CRC errors to check for benign
355 error support. Switched to using a 1-bit grey-scale image with a
356 palette to test for benign errors.

359Imager 0.98 - 3 Jan 2014
360===========
361
f84f86a2
TC
362Incompatible changes:
363
364 - the return value of setpixel() has changed.
365
366 Previously the return values for undrawable pixels vs caller errors
367 changed depending on whether you used the multiple pixel calling
368 mechanism, or the single pixel mechanism.
369
370 Now:
371
372 - for an invalid parameter, such as an unknown colour, or missing
373 parameter, an empty list (or undef in scalar context) is
374 returned, and errstr() is set,
375
376 - otherwise the number of pixels drawn is returned. If none of
377 the pixels could be drawn (they were all outside the image), "0
378 but true" is returned.
379
380 https://rt.cpan.org/Ticket/Display.html?id=87650
381
382Other changes:
383
6ba09ab9
TC
384 - when drawing on an image with an alpha channel where the source
385 minimum is greater than zero, Imager would read from beyond the end
386 of a malloc() allocated buffer. In rare circumstances this could
387 lead to some of the source image not being written to the target
388 image, or possibly to a segmentation fault.
389 I don't believe this has any security concerns beyond that.
390
0d052fd9
TC
391 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
392 text drawn would be nonsense. This would also read beyond the end
393 of a malloced buffer.
394
13671b17
TC
395 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
396 truncated early.
397 https://rt.cpan.org/Ticket/Display.html?id=88993
398

0179ecd6
TC
406 - Image::Probe, Imager's internal module for probing library
407 locations now searches the directories specified by LD_RUN_PATH,
408 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
409 and the corresponing s/\blib$/include/ directories for header
410 files.

437 - TIFF: handle SampleFormat = 2 by translating the signed integer
438 values to unsigned by flipping their sign bits.
439
440 Handle SampleFormat = 3 where possible.
441
442 SampleFormat is ignored for paletted images.
443
237d9e03
TC
444 Mixed SampleFormat are handled incorrectly, since libtiff returns
445 only the first SampleFormat value, and an image with both an alpha
446 channel and SampleFormat = 2 for color channels probably has a
447 different SampleFormat for the alpha channel.

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

706Other changes:
707
708 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
709 internals, those names only matter for the XS interface.
710
711 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
712 the API level compiled into a loadable module such as
713 Imager::File::GIF doesn't match that of Imager. Previously it
714 could be difficult to determine exactly which module was failing to
715 load.
716 https://rt.cpan.org/Ticket/Display.html?id=77173
717
718 - added Imager->check_file_limits() as an interface to the
719 i_int_check_image_file_limits() API.
720
721 - Imager->set_file_limits(reset => 1) now resets the limits to the

735
29b38678
TC
736 - when downconverting samples (eg. from floating point to 8 bit)
737 Imager now rounds the sample value rather than attempting to
738 allocate input values over output values equally. The old
739 behaviour had the probably surprising effect of converting a
740 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
741 2.
742 This may result in slightly different 8 or 16-bit output images.
743
e2a86bac
TC
744 - BI_BITFIELD BMP images were handled incorrectly, both in
745 incorrectly calculating the space required for the masks and in
746 processing the image data itself.
747 https://rt.cpan.org/Ticket/Display.html?id=76736
748
749 - some odd width BMP BI_RLE4 images use run lengths that run one off
750 the edge of the image. Imager now allows this, discarding the
751 extra column.
752
753 - odd length RLE4 runs in BMP images were decoded incorrectly.
754

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

762 - Imager::Probe can now probe for libraries with dependent libraries,
763 common for static linking, eg. libpng requires libz.
764 https://rt.cpan.org/Ticket/Display.html?id=74043
765
766 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
767
768 - added alternative probe configurations that try to link libz, to
769 handle a statically linked libpng.
770 https://rt.cpan.org/Ticket/Display.html?id=74043
771
772 - if a probe includes testcode, Imager::Probe now checks that code as
773 part of the process of checking each configuration rather than as a
774 post test of the found configuration. This allows alternate
775 configurations to be checked if a matching but non-working
776 configuration is found.

855
856 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have

1014 - io_glue I/O buffering re-work:
1015
1016 - reorganize io_glue to do it's own buffering by default
1017
1018 - the unbuffered functions are available as i_io_raw_read() (or
1019 raw_read() from perl) etc but are not recommended for typical
1020 use.
1021
1022 - use the new i_io_peekn() when checking for file magic to avoid
1023 seek, allowing Imager to detect the file type and read the file
1024 from an unseekable stream (for formats that don't use random
1025 access)
1026
1027 - added several new I/O layer API functions.
1028
1029 - fix the TGA performance problem, most noticably on Win32
1030 https://rt.cpan.org/Ticket/Display.html?id=70037

1032 - TIFF now uses wrapper functions of the correct types to avoid casts
1033 https://rt.cpan.org/Ticket/Display.html?id=69912
1034
1035 - the callback IO object did its own buffering, controlled by the
1036 maxbuffer parameter supplied to the read() and write() methods.
1037 This buffering has been removed, to avoid redundancy with the
1038 common io_glue buffering. This also avoids a bug in that code
1039 which could rarely pass a zero length to the read callback and
1040 then panic about the result.
1041
1042 - the callback IO object now tests the result of calling the close
1043 callback, which should return true for success.
1044
1045 - the PNM reader did its own buffering. This buffering has been
1046 removed to avoid redundancy with the common io_glue buffering.
1047
1048 - previously the read handlers for fd and callback I/O layers would
1049 call the underlying interface (POSIX read or your supplied callback)
1050 until it filled the buffer. It now only makes one call.
1051
1052 - added public constructors for I/O layer objects (see Imager::IO)
1053
1054 - all core file handlers now use the i_io_foo() wrappers to gain
1055 access to buffered I/O rather than calling the I/O layer
1056 callbacks directly.
1057
1058 - all core file handlers now check for error on close.
1059
1060 - Backward compatibility: if you hava custom file handlers, you can
1061 use i_io_write() etc since they're available as macros in older
1062 versions of Imager.
1063
1064 - eliminate the final remnants of io_glue_commit_types().
1065
1066 - bump IMAGER_API_VERSION, since the above may break assumptions.
1067
1068 - removed the long unused i_gen_reader() and i_gen_writer() utility
1069 functions.

1131
1132Development release as a sanity check for the types re-work.
8d14daab
TC
1133
1134Massive types re-work:
1135
1136 - the type used internally for pixel co-ordinates and image sizes is
1137 now 64-bit on 64-bit platforms (at least sane ones).
1138
1139 - size_t is now used consistently for memory block sizes.
1140
1141 - since this changes the binary interface, the Imager API version has
1142 been incremented. Any module that uses the API will need to be
1143 rebuilt. In most cases that will be enough, but calls to any APIs
1144 that take a pointer to image sizes may need source changes.
1145
1146 - you should be able to create very large images on 64-bit systems,
1147 if you have enough memory. Successfully created a 32768 x 49192 x
1148 3 channel image, filled with a tiled image and scaled it. The
1149 unscaled image was also successfully saved to a JPEG.
1150
1151 - check the image size before attempting to write BMP, GIF, JPEG,
1152 PNG, SGI, TGA, TIFF images.
1153
1154 - correctly handle reading TGA images over 32767 pixels wide or tall.
1155
1156Incidental changes:
1157
1158 - the gif_left and gif_top tags are now clamped to non-negative
1159 values when writing a GIF image.
1160
1161 - removed dead callback read/write code
1162
1163The default maximum memory size when reading files is now 1G.

TC
1773 - Possible security issue: The floating point sample path for image
1774 based fills had a buffer overflow. This would overwrite the end of
1775 a malloc()ed buffer with double precision floats.

6912d85a 1777 CVE-2008-1928
e02d22d2 1778
de470892
TC
1779 - check that the result of fileno($fh) is defined rather than simply
1780 true when read() or write() is supplied with an fh parameter.
1781 http://rt.cpan.org/Ticket/Display.html?id=35139
1782
1783 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1784 resulting in a SIGSEGV when attempting to scale an image to a size
1785 too large to fit in memory. This is a NULL pointer access issue,
1786 not a buffer overflow.
1787 Added a check for the failure.
1788 scale_calculate() (and hence scale()) will now fail if any of the
1789 scale size parameters are a reference.

1801This release primarily contains changes to improve ease of use -
1802rather than you having to convert images to the appropriate number of
1803channels, Imager handles it internally. How to handle drawing colors
1804and the default combine mode is a thornier problem left for some other
1805release.

1807 - the font libraries are now only initialized when needed.

TC
1810 - moved the imtoc.perl code into Imager::Preprocess
1811
1812 - paste() and rubthrough() now adapt the source image data to the
1813 destination, so you can now safely paste/rubthrough from greyscale
1814 images to color images or back, or from alpha channel images to
1815 noalpha channels or back.
1816 https://rt.cpan.org/Ticket/Display.html?id=30908
1817
1818 - rubthrough() now falls back to pasting when the source doesn't have
1819 an alpha channel. This effectively treats the source as having a
1820 max alpha channel, the right thing to do.
1821 http://rt.cpan.org/Ticket/Display.html?id=29944
1822
1823 - re-worked most of the area filling code to use a common set of
1824 functions when filling.
1825 Corrected normal combine mode.
1826 Rewrote most of the combine modes to match the way the SVG draft
1827 defines them with respect to a translucent source and destination.
1828 Added tests for translucent source and destination.
1829 Added tests to check 8-bit/sample and double/sample combines work
1830 similarly.

1854 - mixing qtype scaling now sets all channels of a pixel to zero if
1855 the pixel has zero coverage (zero alpha). This should produce more
1856 compressible output files.

1859 - removed the pointless #! line from lib/Imager/Font/Wrap.pm
1860 Noticed when I saw:
1861 https://bugzilla.redhat.com/show_bug.cgi?id=166254
1862 I'm not changing the #! lines of the sample code, since it's sample
1863 code, not intended for installation.

1866 - some TGA images weren't being detected correctly as TGA images
1867 https://rt.cpan.org/Ticket/Display.html?id=32925
1868
1869 - handling of the left-over bit for 16-bit/pixel TGA images has been
1870 changed to match the behaviour of the GIMP. Previously the bit
1871 being set was treated as an opaque pixel, but one user reported a
1872 problem with loading such an image. I haven't been able to find any
1873 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1874 I'll match it's behaviour. See issue 114913 in the GIMP's
1875 bugzilla.

1885 - the old dynaload code used Mach API functions to load dynamic
1886 libraries on Mac OS X. These APIs have been deprecated in OS X
1887 10.5 and were causing some build problems.
1888 So henceforth Imager uses the dlopen() family of functions, and you
1889 will need version 10.3 or later of OS X.

2179 - improved documentation of the unsharpmask filter (I hope)
2180 http://rt.cpan.org/Ticket/Display.html?id=25531
2181
2182 - force flushing of the output from i_tt_dump_names() and test output
2183 in t/t35ttfont.t to prevent output from being mixed up.
2184 https://rt.cpan.org/Ticket/Display.html?id=24859
2185
2186 - rewrite a conditional expression as an if() to hopefully work around
2187 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
2188 https://rt.cpan.org/Ticket/Display.html?id=25561
2189

2193Imager 0.55 - 16 Dec 2006
2194===========
2195
2196This is primarily a bug fix release.
2197
2198Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2199
2200There is one new feature:
2201
2202 - the Win32 font driver now supports UTF8 (RT 22166)
2203 http://www.cpanforum.com/threads/3276
2204 http://rt.cpan.org/Ticket/Display.html?id=22166
2205
2206Several bugs were fixed:
2207
2208 - the string() method would not output the string "0"
2209 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2210
2211 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2212 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2213
2214 - the gif_disposal and gif_user_input tags weren't being read from
2215 the file correctly
2216 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2217
2218 - gif.c was failing to build under MSVC
2219 http://rt.cpan.org/Ticket/Display.html?id=23922
2220
2221 - in some cases strings passed to the string() method were treated as
2222 terminated by NUL (chr 0)
2223 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2224
2225 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2226 that's the default build name for zlib on Win32.
2227 http://rt.cpan.org/Ticket/Display.html?id=23064
2228
2229 - search $Config{incpath} for headers too, which we should have been
2230 doing all along.
2231
2232Win32 font driver fixes:
2233
2234 - the global descent value from bounding box was the wrong sign
2235 http://www.cpanforum.com/threads/3276
2236
2237 - if the first or last glyph overflowed the left or right side of the
2238 advance width they would be clipped
2239
2240
2241Imager 0.54 - 14 Sep 2006
2242===========
2243
2244This is primarily a feature release:
2245
2246 - a new qtype value 'mixing' has been added to the scale()
2247 method. This is faster than 'normal', slower than 'preview'. This
2248 is based on the method used by pnmscale, and seems to produce less
2249 blurry results than normal.
2250 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2251
2252 - the rubthrough() method can now render onto images with an alpha
2253 channel.
2254 http://rt.cpan.org/Ticket/Display.html?id=20678
2255
2256 - the read_multi() method now falls back to calling doing a single
2257 image read via the read() method and write_multi() will now fall
2258 back to calling write() if a single image is supplied. This means
2259 you can simply call the read_multi() or write_multi() functions
2260 without having to check if the type is formatted by that method.
2261 http://rt.cpan.org/Ticket/Display.html?id=19457
2262 http://rt.cpan.org/Ticket/Display.html?id=19458
2263
2264 - the GIF loop extension can now be written. If you don't have
2265 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2266 should upgrade.
2267 http://rt.cpan.org/Ticket/Display.html?id=21185
2268
2269 - getscanline() and setscanline() can now read/write palette index
2270 based data from/to the image for paletted images, by setting type to
2271 'index'.
2272 http://rt.cpan.org/Ticket/Display.html?id=20338
2273
2274 - we no longer hassle you to disable GIF support
2275 http://rt.cpan.org/Ticket/Display.html?id=20687
2276
2277 - minor documentation fixes
2278
2279
2280Imager 0.53 - 26 Jul 2006
2281===========
2282
2283This is a bugfix release.
2284
2285Some test code was left in a code path not covered by the test
2286suite. A test was added to cover this code path and the test code was
2287removed.
2288http://rt.cpan.org/Public/Bug/Display.html?id=20705
2289
2290
2291Imager 0.52 - 25 Jul 2006
2292===========
2293
2294This is primarily a feature release, but contains a fair few bug
2295fixes, new features:
2296
2297 - ability to read and write MS Windows ICO and CUR files
2298
2299 - you can now add file format plugins to support new file formats
2300
2301 - add POD coverage tests
2302
2303 - setcolors() and addcolors() now accept color names and so on
2304 instead of requiring Imager::Color objects.
2305 http://rt.cpan.org/Ticket/Display.html?id=20056
2306
2307 - flood_fill() can now fill to a specified border color instead of
2308 just to the area the same color as the seed.
2309 http://rt.cpan.org/Ticket/Display.html?id=19618
2310
2311
2312Bug fixes:
2313
2314 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2315 calculating the advance width.
2316 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2317
2318 - bounding_box for the T1 driver wasn't including leading and
2319 trailing spaces in the bounding box as the other drivers did, it also
2320 produced strange results for empty strings or strings containing only
2321 spaces
2322
2323 - when reading CMYK jpeg images they were being transferred to the
2324 image object as is, producing a four channel image. It only looked ok
2325 due to an old still unfixed Photoshop bug. We now convert from the
2326 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2327 http://rt.cpan.org/Ticket/Display.html?id=20416
2328
2329 - reading a CYMK TIFF would result in a 4 channel image, reading any
2330 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2331 result in an error.
2332 http://rt.cpan.org/Ticket/Display.html?id=20415
2333
2334 - added /usr/local/include to the default include search path, since
2335 we were already searching /usr/local/lib for libraries.
2336
2337And various minor fixes and documentation updates.
2338
2339

2345 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2346
2347 - fix mis-processing of the src_maxx and src_maxy parameters of the
2348 paste() method
2349 http://rt.cpan.org/Public/Bug/Display.html?id=18712
2350
2351 - fix a problem in Imager's "smart" handling of the color parameter

2353 http://rt.cpan.org/Public/Bug/Display.html?id=18561
2354
2355

2357===========

2360 or 4 channel image to jpeg or a 2 channel image to tga where the
2361 output is an in-memeory buffer.
2362 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2363
2364 - fixes an incorrect pointer parameter in the PNG code
2365 http://rt.cpan.org/Public/Bug/Display.html?id=18051
