1Imager release history. Older releases can be found in Changes.old
2
1791cbdb
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.
39
eb7e48c9
TC
40 - Coverity complained a call to i_getcolors(), used by the
41 implementation of the is_bilevel() method could leave the fetched
42 colors uninitialized. Added a return value check.

44Imager 1.008 - 31 Dec 2018
45============
46
75e155e1 47 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
48 This allows file formats that store EXIF data as blobs similarly
49 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 50
b5bbf161 51 - added some more file extensions to image file type mappings
75e155e1
TC
52

72 - the internal i_errors() function now correctly allocates the stack
73 space needed for its result.
74 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
75
76 - t/100-base/020-color.t now uses Imager::Test's test functions
77 instead of its own.

79
344dda51
TC
80 - write_multi() now returns an error result (a false value) if called
81 with a non-(Imager image object). Previously it would typically
82 crash.
83 https://rt.cpan.org/Ticket/Display.html?id=117878
84
85 - improve the documentation of the jpegquality parameter when
86 writing JPEG files.
87
88 - add code to mitigate CVE-2016-1238, Imager will no longer search the
89 default current directory entry in @INC when searching for file
90 format support modules.

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

125Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
126================
127
08914ed1
TC
128 - re-work the t/200-file/400-basic.t to correctly handle failures
129 It's custom ok() function didn't have a prototype and didn't use scalar().
130 This caused ok() to use the note instead of the value being tested when
131 the method called returned an empty list. For an example of the problem
e6226ce5 132 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 133
a2791e47
TC
134 - remove some noise from when Imager tried to work with bugs in old
135 versions of giflib. I can't do much about the new bugs.
08914ed1 136
e6226ce5
TC
137 - the new autolevels filter (Imager 0.99) used an integer for the
138 sample scaling factor which caused the top output level to be too
139 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
140 https://rt.cpan.org/Ticket/Display.html?id=111871
141
e6226ce5 142 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
143 minimum and maximum luminance from the histogram. This slightly
144 reduced the contrast of the output image.
145 https://rt.cpan.org/Ticket/Display.html?id=111871
146
147 - the new autolevels filter now uses a lookup table for 8-bit images
148 to avoid a floating point multiply for each sample.
149 https://rt.cpan.org/Ticket/Display.html?id=111871
150
e6226ce5
TC
151 - fixed several memory leaks detected by valgrind:
152
153 - addcolors() leaked the temporary array of colors supplied to the
154 internal API
155
156 - make_palette() leaked the temporary image array (not the images
157 themselves) passed to the internal API.
158
159 - combine()/i_combine() leaked its working row buffers
160
161 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
162 buffer if there were too many colors
163
164 - getcolorcount()/i_count_colors() leaked the sample buffer if
165 there were too many colors.
166
167 - the nearest_color filter (undocumented until I find a use for it)
168 leaked both temporaries passed to the API and internal buffers
169
a2791e47
TC
170 - the internal process of upgrading a paletted image to a direct
171 color image would leak a context object reference count.
172
173 - a write failure when writing to a GIF file could leak memory.
174
175 - failing to write to a 1-bit/pixel ICO image could leak memory.
176
177 - Imager no longer deliberately leaks the context object from the
178 initial thread. This was done to ensure there was always a context
179 object available, but the code that needed that now handles the
180 lack correctly,
181
e6226ce5
TC
182 - fixed some uninitialized memory usage detected by valgrind:
183
184 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
185 i_matrix_transform_bg() didn't initialize a working color value
186 if there was zero pixel coverage.
187
188 - i_ft2_cp() didn't initialize the complete color when producing an
189 intermediate image. This caused uninitialized value usage when
190 logging the color.

210
0fda3cfd
TC
211 - update 1.002 release notes to include the center change for filled
212 circle drawing.
213
214 - flood_fill() would escape beyond a 4-connected space under some
215 circumstances.
216 Added many more flood_fill() tests.

219Imager 1.002 - 3 Apr 2015
220============
221
334b8922
TC
222 - drawing anti-aliased filled circles is now 10 to 50 times faster
223 depending on the size of the circle.
0fda3cfd
TC
224 This also changed the center from being the center of the pixel to
225 being the top left of the pixel to match the filled arcs drawn by
226 arc().
334b8922
TC
227 https://rt.cpan.org/Ticket/Display.html?id=101682
228
229 - enhancements to polygon filling:
230
231 - added a mode parameter to control how overlapping regions behave
232
233 - added a polypolygon() method to fill more than one polygon at a
234 time
235
236 - polygon filling is now exposed through the API.
237
45c8e262
TC
238 - added colormodel(), alphachannel() and colorchannels() methods.
239 These were added for two reasons:
240
241 - a future version of Imager may allow the number of channels in
242 an image to not directly represent the color model of an image.
243 eg. a greyscale TIFF image with multiple alpha channels.
244
245 - a future version of Imager may allow an image to be read without
246 translation, for example a TIFF file that contains measurements
0fda3cfd 247 from an instrument. Currently Imager transforms the samples into
d96c4de8 248 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
249 the value back.
250
251 An untranslated image would be unusable as image data, so
252 colormodel() would return "unknown" in this case.
253
254 Similarly a CMYK image might be returned as an "unknown" color
255 model image, if the caller chooses to disable translation to
256 RGB.

TC
299 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
300 the blue channel in the generated palette, and allow each color
301 component to be in the range 100..255 instead of just 100..254.
302 Thanks to Ralf Neubauer.
303 https://rt.cpan.org/Ticket/Display.html?id=97086
304
305 - revert "improved the XS for i_io_read() and i_io_raw_read()"
306 This caused problems with older perls and didn't provide much of a
307 performance improvement.
308
5bf25bc2 309 - support Inline 0.57 and later.
6d47a6af 310 Inline 0.57 changed the "with" interface.

TC
336 - Imager::IO->new_buffer() (and hence Imager->read()'s data
337 parameter) now accepts a reference to a scalar as well as just a
338 plain scalar.

340
341 - Imager::IO->new_buffer() now always makes a copy of the passed in

352
6a160bce
TC
353 - added the jpeg_optimize parameter for writing JPEG files. This can
354 significantly reduce file sizes, but uses more memory and time.
355 https://rt.cpan.org/Ticket/Display.html?id=94292
356
14fd9e5d
TC
357 - the autolevels filter now works on the luminosity of the image
358 rather then working per channel. The old autolevels filter is
359 still available as "autolevels_skew".
360 https://rt.cpan.org/Ticket/Display.html?id=94413
361
75d54149
TC
362 - Imager::File::PNG now supports libpng 1.6.10.
363 1.6.10 changed CRC errors from benign errors to normal errors,
364 which broke the test which used CRC errors to check for benign
365 error support. Switched to using a 1-bit grey-scale image with a
366 palette to test for benign errors.

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

TC
416 - Image::Probe, Imager's internal module for probing library
417 locations now searches the directories specified by LD_RUN_PATH,
418 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
419 and the corresponing s/\blib$/include/ directories for header
420 files.

454 Mixed SampleFormat are handled incorrectly, since libtiff returns
455 only the first SampleFormat value, and an image with both an alpha
456 channel and SampleFormat = 2 for color channels probably has a
457 different SampleFormat for the alpha channel.

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

716Other changes:
717
718 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
719 internals, those names only matter for the XS interface.
720
721 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
722 the API level compiled into a loadable module such as
723 Imager::File::GIF doesn't match that of Imager. Previously it
724 could be difficult to determine exactly which module was failing to
725 load.
726 https://rt.cpan.org/Ticket/Display.html?id=77173
727
728 - added Imager->check_file_limits() as an interface to the
729 i_int_check_image_file_limits() API.
730
731 - Imager->set_file_limits(reset => 1) now resets the limits to the

745
29b38678
TC
746 - when downconverting samples (eg. from floating point to 8 bit)
747 Imager now rounds the sample value rather than attempting to
748 allocate input values over output values equally. The old
749 behaviour had the probably surprising effect of converting a
750 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
751 2.
752 This may result in slightly different 8 or 16-bit output images.
753
e2a86bac
TC
754 - BI_BITFIELD BMP images were handled incorrectly, both in
755 incorrectly calculating the space required for the masks and in
756 processing the image data itself.
757 https://rt.cpan.org/Ticket/Display.html?id=76736
758
759 - some odd width BMP BI_RLE4 images use run lengths that run one off
760 the edge of the image. Imager now allows this, discarding the
761 extra column.
762
763 - odd length RLE4 runs in BMP images were decoded incorrectly.

765 - pkg-config could sometimes return a library that was in a directory
766 EU::MM / $Config{libpth} doesn't know about, but the compiler did.

768 EU::MM can find the library, and if not, search our configured

773 common for static linking, eg. libpng requires libz.
774 https://rt.cpan.org/Ticket/Display.html?id=74043
775
776 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.

779 handle a statically linked libpng.
780 https://rt.cpan.org/Ticket/Display.html?id=74043
781
782 - if a probe includes testcode, Imager::Probe now checks that code as
783 part of the process of checking each configuration rather than as a
784 post test of the found configuration. This allows alternate
785 configurations to be checked if a matching but non-working
786 configuration is found.

TC
1024 - io_glue I/O buffering re-work:
1025
1026 - reorganize io_glue to do it's own buffering by default
1027
1028 - the unbuffered functions are available as i_io_raw_read() (or
1029 raw_read() from perl) etc but are not recommended for typical
1030 use.
1031
1032 - use the new i_io_peekn() when checking for file magic to avoid
1033 seek, allowing Imager to detect the file type and read the file
1034 from an unseekable stream (for formats that don't use random
1035 access)
1036
1037 - added several new I/O layer API functions.
1038
1039 - fix the TGA performance problem, most noticably on Win32
1040 https://rt.cpan.org/Ticket/Display.html?id=70037
1041
1042 - TIFF now uses wrapper functions of the correct types to avoid casts
1043 https://rt.cpan.org/Ticket/Display.html?id=69912
1044
1045 - the callback IO object did its own buffering, controlled by the
1046 maxbuffer parameter supplied to the read() and write() methods.
1047 This buffering has been removed, to avoid redundancy with the
1048 common io_glue buffering. This also avoids a bug in that code
1049 which could rarely pass a zero length to the read callback and
1050 then panic about the result.
1051
1052 - the callback IO object now tests the result of calling the close
1053 callback, which should return true for success.
1054
1055 - the PNM reader did its own buffering. This buffering has been
1056 removed to avoid redundancy with the common io_glue buffering.
1057
1058 - previously the read handlers for fd and callback I/O layers would
1059 call the underlying interface (POSIX read or your supplied callback)
1060 until it filled the buffer. It now only makes one call.
1061
1062 - added public constructors for I/O layer objects (see Imager::IO)
1063
1064 - all core file handlers now use the i_io_foo() wrappers to gain
1065 access to buffered I/O rather than calling the I/O layer
1066 callbacks directly.
1067
1068 - all core file handlers now check for error on close.
1069
1070 - Backward compatibility: if you hava custom file handlers, you can
1071 use i_io_write() etc since they're available as macros in older
1072 versions of Imager.
1073
1074 - eliminate the final remnants of io_glue_commit_types().
1075
1076 - bump IMAGER_API_VERSION, since the above may break assumptions.
1077
1078 - removed the long unused i_gen_reader() and i_gen_writer() utility
1079 functions.

1084The main changes in the release versus 0.84 are:

1087 dimensions and co-ordinated, and for memory block sizes.
1088
1089 - handle IFD loops in TIFF files correctly. Previously this would
1090 lead to an infinite loop.

1142Development release as a sanity check for the types re-work.
8d14daab
TC
1143
1144Massive types re-work:
1145
1146 - the type used internally for pixel co-ordinates and image sizes is
1147 now 64-bit on 64-bit platforms (at least sane ones).
1148
1149 - size_t is now used consistently for memory block sizes.
1150
1151 - since this changes the binary interface, the Imager API version has
1152 been incremented. Any module that uses the API will need to be
1153 rebuilt. In most cases that will be enough, but calls to any APIs
1154 that take a pointer to image sizes may need source changes.
1155
1156 - you should be able to create very large images on 64-bit systems,
1157 if you have enough memory. Successfully created a 32768 x 49192 x
1158 3 channel image, filled with a tiled image and scaled it. The
1159 unscaled image was also successfully saved to a JPEG.
1160
1161 - check the image size before attempting to write BMP, GIF, JPEG,
1162 PNG, SGI, TGA, TIFF images.
1163
1164 - correctly handle reading TGA images over 32767 pixels wide or tall.
1165
1166Incidental changes:
1167
1168 - the gif_left and gif_top tags are now clamped to non-negative
1169 values when writing a GIF image.
1170
1171 - removed dead callback read/write code
1172
1173The default maximum memory size when reading files is now 1G.

1783 - Possible security issue: The floating point sample path for image
1784 based fills had a buffer overflow. This would overwrite the end of
1785 a malloc()ed buffer with double precision floats.

1789 - check that the result of fileno($fh) is defined rather than simply
1790 true when read() or write() is supplied with an fh parameter.
1791 http://rt.cpan.org/Ticket/Display.html?id=35139
1792
1793 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1794 resulting in a SIGSEGV when attempting to scale an image to a size
1795 too large to fit in memory. This is a NULL pointer access issue,
1796 not a buffer overflow.
1797 Added a check for the failure.
1798 scale_calculate() (and hence scale()) will now fail if any of the
1799 scale size parameters are a reference.

1811This release primarily contains changes to improve ease of use -
1812rather than you having to convert images to the appropriate number of
1813channels, Imager handles it internally. How to handle drawing colors
1814and the default combine mode is a thornier problem left for some other
1815release.

TC
1820 - moved the imtoc.perl code into Imager::Preprocess
1821
1822 - paste() and rubthrough() now adapt the source image data to the
1823 destination, so you can now safely paste/rubthrough from greyscale
1824 images to color images or back, or from alpha channel images to
1825 noalpha channels or back.
1826 https://rt.cpan.org/Ticket/Display.html?id=30908
1827
1828 - rubthrough() now falls back to pasting when the source doesn't have
1829 an alpha channel. This effectively treats the source as having a
1830 max alpha channel, the right thing to do.
1831 http://rt.cpan.org/Ticket/Display.html?id=29944
1832
1833 - re-worked most of the area filling code to use a common set of
1834 functions when filling.
1835 Corrected normal combine mode.
1836 Rewrote most of the combine modes to match the way the SVG draft
1837 defines them with respect to a translucent source and destination.
1838 Added tests for translucent source and destination.
1839 Added tests to check 8-bit/sample and double/sample combines work
1840 similarly.

1876 - some TGA images weren't being detected correctly as TGA images
1877 https://rt.cpan.org/Ticket/Display.html?id=32925
1878
1879 - handling of the left-over bit for 16-bit/pixel TGA images has been
1880 changed to match the behaviour of the GIMP. Previously the bit
1881 being set was treated as an opaque pixel, but one user reported a
1882 problem with loading such an image. I haven't been able to find any
1883 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1884 I'll match it's behaviour. See issue 114913 in the GIMP's
1885 bugzilla.

1895 - the old dynaload code used Mach API functions to load dynamic
1896 libraries on Mac OS X. These APIs have been deprecated in OS X
1897 10.5 and were causing some build problems.

1899 will need version 10.3 or later of OS X.

2179 http://rt.cpan.org/Ticket/Display.html?id=11972
2180
2181 - reading bmp files now consitently handles short reads. You can now
2182 supply a parameter to treat a short read as successful and set
2183 i_incomplete
2184 http://rt.cpan.org/Ticket/Display.html?id=8426
2185
2186 - previously, reading ASCII PBM files required spaces between samples,
2187 even though the format doesn't require that

2203Imager 0.55 - 16 Dec 2006
2204===========
2205
2206This is primarily a bug fix release.
2207
2208Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2209
2210There is one new feature:
2211
2212 - the Win32 font driver now supports UTF8 (RT 22166)
2213 http://www.cpanforum.com/threads/3276
2214 http://rt.cpan.org/Ticket/Display.html?id=22166
2215
2216Several bugs were fixed:
2217
2218 - the string() method would not output the string "0"
2219 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2220
2221 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2222 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2223
2224 - the gif_disposal and gif_user_input tags weren't being read from
2225 the file correctly
2226 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2227
2228 - gif.c was failing to build under MSVC
2229 http://rt.cpan.org/Ticket/Display.html?id=23922
2230
2231 - in some cases strings passed to the string() method were treated as
2232 terminated by NUL (chr 0)
2233 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2234
2235 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2236 that's the default build name for zlib on Win32.
2237 http://rt.cpan.org/Ticket/Display.html?id=23064
2238
2239 - search $Config{incpath} for headers too, which we should have been
2240 doing all along.
2241
2242Win32 font driver fixes:
2243
2244 - the global descent value from bounding box was the wrong sign
2245 http://www.cpanforum.com/threads/3276
2246
2247 - if the first or last glyph overflowed the left or right side of the
2248 advance width they would be clipped
2249
2250
2251Imager 0.54 - 14 Sep 2006
2252===========
2253
2254This is primarily a feature release:
2255
2256 - a new qtype value 'mixing' has been added to the scale()
2257 method. This is faster than 'normal', slower than 'preview'. This
2258 is based on the method used by pnmscale, and seems to produce less
2259 blurry results than normal.
2260 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2261
2262 - the rubthrough() method can now render onto images with an alpha
2263 channel.
2264 http://rt.cpan.org/Ticket/Display.html?id=20678
2265
2266 - the read_multi() method now falls back to calling doing a single
2267 image read via the read() method and write_multi() will now fall
2268 back to calling write() if a single image is supplied. This means
2269 you can simply call the read_multi() or write_multi() functions
2270 without having to check if the type is formatted by that method.
2271 http://rt.cpan.org/Ticket/Display.html?id=19457
2272 http://rt.cpan.org/Ticket/Display.html?id=19458
2273
2274 - the GIF loop extension can now be written. If you don't have
2275 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2276 should upgrade.
2277 http://rt.cpan.org/Ticket/Display.html?id=21185
2278
2279 - getscanline() and setscanline() can now read/write palette index
2280 based data from/to the image for paletted images, by setting type to
2281 'index'.
2282 http://rt.cpan.org/Ticket/Display.html?id=20338
2283
2284 - we no longer hassle you to disable GIF support
2285 http://rt.cpan.org/Ticket/Display.html?id=20687
2286
2287 - minor documentation fixes
2288
2289
2290Imager 0.53 - 26 Jul 2006
2291===========
2292
2293This is a bugfix release.
2294
2295Some test code was left in a code path not covered by the test
2296suite. A test was added to cover this code path and the test code was
2297removed.
2298http://rt.cpan.org/Public/Bug/Display.html?id=20705
2299
2300
2301Imager 0.52 - 25 Jul 2006
2302===========
2303
2304This is primarily a feature release, but contains a fair few bug
2305fixes, new features:
2306
2307 - ability to read and write MS Windows ICO and CUR files
2308
2309 - you can now add file format plugins to support new file formats
2310
2311 - add POD coverage tests
2312
2313 - setcolors() and addcolors() now accept color names and so on
2314 instead of requiring Imager::Color objects.
2315 http://rt.cpan.org/Ticket/Display.html?id=20056
2316
2317 - flood_fill() can now fill to a specified border color instead of
2318 just to the area the same color as the seed.
2319 http://rt.cpan.org/Ticket/Display.html?id=19618
2320
2321
2322Bug fixes:
2323
2324 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2325 calculating the advance width.
2326 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2327
2328 - bounding_box for the T1 driver wasn't including leading and
2329 trailing spaces in the bounding box as the other drivers did, it also
2330 produced strange results for empty strings or strings containing only
2331 spaces
2332
2333 - when reading CMYK jpeg images they were being transferred to the
2334 image object as is, producing a four channel image. It only looked ok
2335 due to an old still unfixed Photoshop bug. We now convert from the
2336 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2337 http://rt.cpan.org/Ticket/Display.html?id=20416
2338
2339 - reading a CYMK TIFF would result in a 4 channel image, reading any
2340 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2341 result in an error.
2342 http://rt.cpan.org/Ticket/Display.html?id=20415
2343
2344 - added /usr/local/include to the default include search path, since
2345 we were already searching /usr/local/lib for libraries.
2346
2347And various minor fixes and documentation updates.
2348
2349
2350Imager 0.51 - 23 Apr 2006

2354 a crash
2355 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2356
2357 - fix mis-processing of the src_maxx and src_maxy parameters of the
2358 paste() method
2359 http://rt.cpan.org/Public/Bug/Display.html?id=18712
2360
2361 - fix a problem in Imager's "smart" handling of the color parameter
2362 to various methods.
2363 http://rt.cpan.org/Public/Bug/Display.html?id=18561
2364
2365
2366Imager 0.50 - 29 Mar 2006
2367===========
2368
2369 - CRITICAL: fixes a segmentation fault from attempting to write a 2
2370 or 4 channel image to jpeg or a 2 channel image to tga where the
2371 output is an in-memeory buffer.
2372 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2373
2374 - fixes an incorrect pointer parameter in the PNG code
2375 http://rt.cpan.org/Public/Bug/Display.html?id=18051
2376
2377 - skip Inline::C tests when building in a directory with spaces
2378 http://rt.cpan.org/Public/Bug/Display.html?id=18049
