1791cbdb
TC
3Coverity finally finished a build, fix a few problems:
4
8445279e
TC
5High severity:
6
1791cbdb 7 - reading a color-mapped TGA file with an id string would cause a
8445279e 8 double-free if the palette was truncated. CID 185317.
1791cbdb 9
6494c395
TC
10 - mixing scaling to sizes where the accumulator row, the working
11 output row or the working input row didn't fit into the address
12 space could result in memory leaks. This can probably only be
8445279e 13 reproduced on very wide floating-point sample images. CID 185318.
6494c395 14
fc24ca5f 15 - convert an array style function parameter pointer to pointer style
3d7b055c 16 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 17 CID 185343.
3d7b055c 18
8445279e 19 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 20
20c297d4 21 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 22 implementation. CID 185303.
20c297d4 23
fc24ca5f 24 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 25 drawing (it should always end up being set.) CID 185341.
fc24ca5f 26
f7675b46 27 - addi style makemap could potentially read one past the end of an
8445279e 28 array. CID 185337.
f7675b46 29
58ec1fde
TC
30 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
31 would result in read beyond the end of the built-in hatch array.
32 Negative values (which Coverity didn't complain about) could also
8445279e 33 cause problems. CID 185331.
58ec1fde 34
b7346865
TC
35 - the Imager::Color set_internal() interal method no longer
36 calls the over-complicated ICL_set_internal() (which is retained
37 only for the old API.) Coverity complained that this leaked, but
38 this could only occur with an invalid (NULL pointer) color object.
8445279e 39 CID 185323.
b7346865 40
785364c1
TC
41 - the underlying implementation of the map() method could read before
42 the beginning on an allocated array if supplied with inconsistent
43 parameters, which Coverity complained about. No Imager code calls
44 that function with inconsistent parameters, but a
8445279e 45 belt-and-suspenders check was added. CID 185315.
785364c1 46
eb7e48c9
TC
47 - Coverity complained a call to i_getcolors(), used by the
48 implementation of the is_bilevel() method could leave the fetched
8445279e 49 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 50
c1c8b1e9
TC
51 - a numeric combining mode of 13 (eg. as a parameter to
52 Imager::Fill->new())could cause an invalid array read in
53 i_get_combine() due to a fencepost error in validating the combine
8445279e 54 number. CID 185299.
c1c8b1e9 55
c4fd43be
TC
56
57
58 - avoid an unneeded EXTEND() call when the FT1 has_chars()
59 implementation returns 0. CID 185350.
60
61 - avoid accessing a possibly NULL map from MakeMapObject() in a
62 logging call. (GIF) CID 185296.
63
4615ad8d
TC
64 - gradgen() allocated the wrong amount of space (always too much) for
65 the color array. CID 185291.

67Imager 1.008 - 31 Dec 2018
68============
69
75e155e1 70 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
71 This allows file formats that store EXIF data as blobs similarly
72 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 73
b5bbf161 74 - added some more file extensions to image file type mappings
75e155e1
TC
75
76 - added add_type_extensions() class method

TC
92Imager 1.006 - 26 Aug 2017
93============
94
ba7ddbae
TC
95 - the internal i_errors() function now correctly allocates the stack
96 space needed for its result.
97 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
98
99 - t/100-base/020-color.t now uses Imager::Test's test functions
100 instead of its own.
101 https://rt.cpan.org/Ticket/Display.html?id=111993
102
344dda51
TC
103 - write_multi() now returns an error result (a false value) if called
104 with a non-(Imager image object). Previously it would typically
105 crash.
106 https://rt.cpan.org/Ticket/Display.html?id=117878
107
108 - improve the documentation of the jpegquality parameter when
109 writing JPEG files.
110
111 - add code to mitigate CVE-2016-1238, Imager will no longer search the
112 default current directory entry in @INC when searching for file
113 format support modules.

121 - revert the ivdformat probes, they don't work as is and trying to
122 fix them is too much work for now.

TC
124Imager 1.004_004 - 15 Apr 2016
125================
126
9c45cc49
TC
127 - test that the ivdformat from Config is correct and look for a valid
128 one if it isn't.
129 For the strange Win32 failures.
130
131 - fix a copy and paste error in pod in samples/samp-form.cgi

TC
133Imager 1.004_003 - 23 Mar 2016
134================
135
bd2d657d
TC
136 - add some extra error reporting to the I/O layers tests, this might
137 help catch a failure seen on Win32.

140Imager 1.004_002 - 20 Mar 2016
141================
142
735b3e7b
TC
143 - don't use the seek() method on opened() handles in
144 t/200-file/400-basic.t. In older versions of perl such handles are
145 only IO::Handle objects, not IO::File, and don't have a seek()
146 method.

TC
148Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
149================
150
08914ed1
TC
151 - re-work the t/200-file/400-basic.t to correctly handle failures
152 It's custom ok() function didn't have a prototype and didn't use scalar().
153 This caused ok() to use the note instead of the value being tested when
154 the method called returned an empty list. For an example of the problem
e6226ce5 155 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 156
a2791e47
TC
157 - remove some noise from when Imager tried to work with bugs in old
158 versions of giflib. I can't do much about the new bugs.
08914ed1 159
e6226ce5
TC
160 - the new autolevels filter (Imager 0.99) used an integer for the
161 sample scaling factor which caused the top output level to be too
162 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
163 https://rt.cpan.org/Ticket/Display.html?id=111871
164
e6226ce5 165 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
166 minimum and maximum luminance from the histogram. This slightly
167 reduced the contrast of the output image.
168 https://rt.cpan.org/Ticket/Display.html?id=111871
169
170 - the new autolevels filter now uses a lookup table for 8-bit images
171 to avoid a floating point multiply for each sample.
172 https://rt.cpan.org/Ticket/Display.html?id=111871
173
e6226ce5
TC
174 - fixed several memory leaks detected by valgrind:
175
176 - addcolors() leaked the temporary array of colors supplied to the
177 internal API
178
179 - make_palette() leaked the temporary image array (not the images
180 themselves) passed to the internal API.
181
182 - combine()/i_combine() leaked its working row buffers
183
184 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
185 buffer if there were too many colors
186
187 - getcolorcount()/i_count_colors() leaked the sample buffer if
188 there were too many colors.
189
190 - the nearest_color filter (undocumented until I find a use for it)
191 leaked both temporaries passed to the API and internal buffers
192
a2791e47
TC
193 - the internal process of upgrading a paletted image to a direct
194 color image would leak a context object reference count.
195
196 - a write failure when writing to a GIF file could leak memory.
197
198 - failing to write to a 1-bit/pixel ICO image could leak memory.
199
200 - Imager no longer deliberately leaks the context object from the
201 initial thread. This was done to ensure there was always a context
202 object available, but the code that needed that now handles the
203 lack correctly,
204
e6226ce5
TC
205 - fixed some uninitialized memory usage detected by valgrind:
206
207 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
208 i_matrix_transform_bg() didn't initialize a working color value
209 if there was zero pixel coverage.
210
211 - i_ft2_cp() didn't initialize the complete color when producing an
212 intermediate image. This caused uninitialized value usage when
213 logging the color.

218 - Imager::Color::Table is now pre-loaded by the preload() method.
219 https://rt.cpan.org/Ticket/Display.html?id=104896
220
221 - fix an assertion triggered under perl 5.23.4.
222 Thanks to A. Sinan Unur for the report and the patch.

231Imager 1.003 - 12 May 2015
232============
233
0fda3cfd
TC
234 - update 1.002 release notes to include the center change for filled
235 circle drawing.
236
237 - flood_fill() would escape beyond a 4-connected space under some
238 circumstances.
239 Added many more flood_fill() tests.

TC
242Imager 1.002 - 3 Apr 2015
243============
244
334b8922
TC
245 - drawing anti-aliased filled circles is now 10 to 50 times faster
246 depending on the size of the circle.
0fda3cfd
TC
247 This also changed the center from being the center of the pixel to
248 being the top left of the pixel to match the filled arcs drawn by
249 arc().
334b8922
TC
250 https://rt.cpan.org/Ticket/Display.html?id=101682
251
252 - enhancements to polygon filling:
253
254 - added a mode parameter to control how overlapping regions behave
255
256 - added a polypolygon() method to fill more than one polygon at a
257 time
258
259 - polygon filling is now exposed through the API.
260
45c8e262
TC
261 - added colormodel(), alphachannel() and colorchannels() methods.
262 These were added for two reasons:
263
264 - a future version of Imager may allow the number of channels in
265 an image to not directly represent the color model of an image.
266 eg. a greyscale TIFF image with multiple alpha channels.
267
268 - a future version of Imager may allow an image to be read without
269 translation, for example a TIFF file that contains measurements
0fda3cfd 270 from an instrument. Currently Imager transforms the samples into
d96c4de8 271 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
272 the value back.
273
274 An untranslated image would be unusable as image data, so
275 colormodel() would return "unknown" in this case.
276
277 Similarly a CMYK image might be returned as an "unknown" color
278 model image, if the caller chooses to disable translation to
279 RGB.

320==============
321
5dab5b9a
TC
322 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
323 the blue channel in the generated palette, and allow each color
324 component to be in the range 100..255 instead of just 100..254.
325 Thanks to Ralf Neubauer.
326 https://rt.cpan.org/Ticket/Display.html?id=97086
327
328 - revert "improved the XS for i_io_read() and i_io_raw_read()"
329 This caused problems with older perls and didn't provide much of a
330 performance improvement.
331
5bf25bc2 332 - support Inline 0.57 and later.
6d47a6af 333 Inline 0.57 changed the "with" interface.

343 - GIF: add support for giflib 5.1.0, which added error code pointer
344 parameters to EGifCloseFile() and DGifCloseFile().

357===========
358
dce1523b
TC
359 - Imager::IO->new_buffer() (and hence Imager->read()'s data
360 parameter) now accepts a reference to a scalar as well as just a
361 plain scalar.
6a160bce 362 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
363
364 - Imager::IO->new_buffer() now always makes a copy of the passed in
365 buffer to avoid problems with temporary objects used for the return
366 value of SvPVbyte().

371
372 - load plugins from absolute paths on Android
373 Thanks to Brian Fraser.
374 https://rt.cpan.org/Ticket/Display.html?id=93272
375
6a160bce
TC
376 - added the jpeg_optimize parameter for writing JPEG files. This can
377 significantly reduce file sizes, but uses more memory and time.
378 https://rt.cpan.org/Ticket/Display.html?id=94292
379
14fd9e5d
TC
380 - the autolevels filter now works on the luminosity of the image
381 rather then working per channel. The old autolevels filter is
382 still available as "autolevels_skew".
383 https://rt.cpan.org/Ticket/Display.html?id=94413
384
75d54149
TC
385 - Imager::File::PNG now supports libpng 1.6.10.
386 1.6.10 changed CRC errors from benign errors to normal errors,
387 which broke the test which used CRC errors to check for benign
388 error support. Switched to using a 1-bit grey-scale image with a
389 palette to test for benign errors.

392Imager 0.98 - 3 Jan 2014
393===========
394
f84f86a2
TC
395Incompatible changes:
396
397 - the return value of setpixel() has changed.
398
399 Previously the return values for undrawable pixels vs caller errors
400 changed depending on whether you used the multiple pixel calling
401 mechanism, or the single pixel mechanism.
402
403 Now:
404
405 - for an invalid parameter, such as an unknown colour, or missing
406 parameter, an empty list (or undef in scalar context) is
407 returned, and errstr() is set,
408
409 - otherwise the number of pixels drawn is returned. If none of
410 the pixels could be drawn (they were all outside the image), "0
411 but true" is returned.
412
413 https://rt.cpan.org/Ticket/Display.html?id=87650
414
415Other changes:
416
6ba09ab9
TC
417 - when drawing on an image with an alpha channel where the source
418 minimum is greater than zero, Imager would read from beyond the end
419 of a malloc() allocated buffer. In rare circumstances this could
420 lead to some of the source image not being written to the target
421 image, or possibly to a segmentation fault.
422 I don't believe this has any security concerns beyond that.
423
0d052fd9
TC
424 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
425 text drawn would be nonsense. This would also read beyond the end
426 of a malloced buffer.
427
13671b17
TC
428 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
429 truncated early.
430 https://rt.cpan.org/Ticket/Display.html?id=88993
431
d6f4e964

432 - Imager::Font::Wrap no longer requires the image parameter.

477 Mixed SampleFormat are handled incorrectly, since libtiff returns
478 only the first SampleFormat value, and an image with both an alpha
479 channel and SampleFormat = 2 for color channels probably has a
480 different SampleFormat for the alpha channel.

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

739Other changes:
740
741 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
742 internals, those names only matter for the XS interface.
743
744 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
745 the API level compiled into a loadable module such as
746 Imager::File::GIF doesn't match that of Imager. Previously it
747 could be difficult to determine exactly which module was failing to
748 load.
749 https://rt.cpan.org/Ticket/Display.html?id=77173
750
751 - added Imager->check_file_limits() as an interface to the
752 i_int_check_image_file_limits() API.
753
754 - Imager->set_file_limits(reset => 1) now resets the limits to the

TC
769 - when downconverting samples (eg. from floating point to 8 bit)
770 Imager now rounds the sample value rather than attempting to
771 allocate input values over output values equally. The old
772 behaviour had the probably surprising effect of converting a
773 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
774 2.
775 This may result in slightly different 8 or 16-bit output images.
776
e2a86bac
TC
777 - BI_BITFIELD BMP images were handled incorrectly, both in
778 incorrectly calculating the space required for the masks and in
779 processing the image data itself.
780 https://rt.cpan.org/Ticket/Display.html?id=76736
781
782 - some odd width BMP BI_RLE4 images use run lengths that run one off
783 the edge of the image. Imager now allows this, discarding the
784 extra column.
785
786 - odd length RLE4 runs in BMP images were decoded incorrectly.

788 - pkg-config could sometimes return a library that was in a directory

796 common for static linking, eg. libpng requires libz.

798
799 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.

802 handle a statically linked libpng.
803 https://rt.cpan.org/Ticket/Display.html?id=74043
804
805 - if a probe includes testcode, Imager::Probe now checks that code as
806 part of the process of checking each configuration rather than as a
807 post test of the found configuration. This allows alternate
808 configurations to be checked if a matching but non-working
809 configuration is found.

889 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
890 changed to make better use of the typemap, but these aren't part of
891 the perl level API anyway. There were no changes to the C level

1047 - io_glue I/O buffering re-work:
1048
1049 - reorganize io_glue to do it's own buffering by default
1050
1051 - the unbuffered functions are available as i_io_raw_read() (or
1052 raw_read() from perl) etc but are not recommended for typical
1053 use.
1054
1055 - use the new i_io_peekn() when checking for file magic to avoid
1056 seek, allowing Imager to detect the file type and read the file
1057 from an unseekable stream (for formats that don't use random
1058 access)
1059
1060 - added several new I/O layer API functions.
1061
1062 - fix the TGA performance problem, most noticably on Win32
1063 https://rt.cpan.org/Ticket/Display.html?id=70037

1065 - TIFF now uses wrapper functions of the correct types to avoid casts
1066 https://rt.cpan.org/Ticket/Display.html?id=69912
1067
1068 - the callback IO object did its own buffering, controlled by the
1069 maxbuffer parameter supplied to the read() and write() methods.
1070 This buffering has been removed, to avoid redundancy with the
1071 common io_glue buffering. This also avoids a bug in that code
1072 which could rarely pass a zero length to the read callback and
1073 then panic about the result.
1074
1075 - the callback IO object now tests the result of calling the close
1076 callback, which should return true for success.
1077
1078 - the PNM reader did its own buffering. This buffering has been
1079 removed to avoid redundancy with the common io_glue buffering.
1080
1081 - previously the read handlers for fd and callback I/O layers would
1082 call the underlying interface (POSIX read or your supplied callback)
1083 until it filled the buffer. It now only makes one call.
1084
1085 - added public constructors for I/O layer objects (see Imager::IO)
1086
1087 - all core file handlers now use the i_io_foo() wrappers to gain
1088 access to buffered I/O rather than calling the I/O layer
1089 callbacks directly.
1090
1091 - all core file handlers now check for error on close.
1092
1093 - Backward compatibility: if you hava custom file handlers, you can
1094 use i_io_write() etc since they're available as macros in older
1095 versions of Imager.
1096
1097 - eliminate the final remnants of io_glue_commit_types().
1098
1099 - bump IMAGER_API_VERSION, since the above may break assumptions.
1100
1101 - removed the long unused i_gen_reader() and i_gen_writer() utility
1102 functions.

1165Development release as a sanity check for the types re-work.

TC
1166
1167Massive types re-work:
1168
1169 - the type used internally for pixel co-ordinates and image sizes is
1170 now 64-bit on 64-bit platforms (at least sane ones).
1171
1172 - size_t is now used consistently for memory block sizes.
1173
1174 - since this changes the binary interface, the Imager API version has
1175 been incremented. Any module that uses the API will need to be
1176 rebuilt. In most cases that will be enough, but calls to any APIs
1177 that take a pointer to image sizes may need source changes.
1178
1179 - you should be able to create very large images on 64-bit systems,
1180 if you have enough memory. Successfully created a 32768 x 49192 x
1181 3 channel image, filled with a tiled image and scaled it. The
1182 unscaled image was also successfully saved to a JPEG.
1183
1184 - check the image size before attempting to write BMP, GIF, JPEG,
1185 PNG, SGI, TGA, TIFF images.
1186
1187 - correctly handle reading TGA images over 32767 pixels wide or tall.
1188
1189Incidental changes:
1190
1191 - the gif_left and gif_top tags are now clamped to non-negative
1192 values when writing a GIF image.
1193
1194 - removed dead callback read/write code
1195
1196The default maximum memory size when reading files is now 1G.

1834This release primarily contains changes to improve ease of use -
1835rather than you having to convert images to the appropriate number of
1836channels, Imager handles it internally. How to handle drawing colors
1837and the default combine mode is a thornier problem left for some other
1838release.

TC
1843 - moved the imtoc.perl code into Imager::Preprocess
1844
1845 - paste() and rubthrough() now adapt the source image data to the
1846 destination, so you can now safely paste/rubthrough from greyscale
1847 images to color images or back, or from alpha channel images to
1848 noalpha channels or back.
1849 https://rt.cpan.org/Ticket/Display.html?id=30908
1850
1851 - rubthrough() now falls back to pasting when the source doesn't have
1852 an alpha channel. This effectively treats the source as having a
1853 max alpha channel, the right thing to do.
1854 http://rt.cpan.org/Ticket/Display.html?id=29944
1855
1856 - re-worked most of the area filling code to use a common set of
1857 functions when filling.
1858 Corrected normal combine mode.
1859 Rewrote most of the combine modes to match the way the SVG draft
1860 defines them with respect to a translucent source and destination.
1861 Added tests for translucent source and destination.
1862 Added tests to check 8-bit/sample and double/sample combines work
1863 similarly.

1902 - handling of the left-over bit for 16-bit/pixel TGA images has been
1903 changed to match the behaviour of the GIMP. Previously the bit
1904 being set was treated as an opaque pixel, but one user reported a
1905 problem with loading such an image. I haven't been able to find any
1906 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1907 I'll match it's behaviour. See issue 114913 in the GIMP's
1908 bugzilla.

1918 - the old dynaload code used Mach API functions to load dynamic
1919 libraries on Mac OS X. These APIs have been deprecated in OS X

2194Bug fixes:
2195
2196 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
2197 was returning an image object with an extra reference, this
2198 resulted in a memory leak.

2226Imager 0.55 - 16 Dec 2006
2227===========
2228
2229This is primarily a bug fix release.
2230
2231Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2232
2233There is one new feature:
2234
2235 - the Win32 font driver now supports UTF8 (RT 22166)
2236 http://www.cpanforum.com/threads/3276
2237 http://rt.cpan.org/Ticket/Display.html?id=22166
2238
2239Several bugs were fixed:
2240
2241 - the string() method would not output the string "0"
2242 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2243
2244 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2245 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2246
2247 - the gif_disposal and gif_user_input tags weren't being read from
2248 the file correctly
2249 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2250
2251 - gif.c was failing to build under MSVC
2252 http://rt.cpan.org/Ticket/Display.html?id=23922
2253
2254 - in some cases strings passed to the string() method were treated as
2255 terminated by NUL (chr 0)
2256 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2257
2258 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2259 that's the default build name for zlib on Win32.
2260 http://rt.cpan.org/Ticket/Display.html?id=23064
2261
2262 - search $Config{incpath} for headers too, which we should have been
2263 doing all along.
2264
2265Win32 font driver fixes:
2266
2267 - the global descent value from bounding box was the wrong sign
2268 http://www.cpanforum.com/threads/3276
2269
2270 - if the first or last glyph overflowed the left or right side of the
2271 advance width they would be clipped
2272
2273
2274Imager 0.54 - 14 Sep 2006
2275===========
2276
2277This is primarily a feature release:
2278
2279 - a new qtype value 'mixing' has been added to the scale()
2280 method. This is faster than 'normal', slower than 'preview'. This
2281 is based on the method used by pnmscale, and seems to produce less
2282 blurry results than normal.
2283 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2284
2285 - the rubthrough() method can now render onto images with an alpha
2286 channel.
2287 http://rt.cpan.org/Ticket/Display.html?id=20678
2288
2289 - the read_multi() method now falls back to calling doing a single
2290 image read via the read() method and write_multi() will now fall
2291 back to calling write() if a single image is supplied. This means
2292 you can simply call the read_multi() or write_multi() functions
2293 without having to check if the type is formatted by that method.
2294 http://rt.cpan.org/Ticket/Display.html?id=19457
2295 http://rt.cpan.org/Ticket/Display.html?id=19458
2296
2297 - the GIF loop extension can now be written. If you don't have
2298 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2299 should upgrade.
2300 http://rt.cpan.org/Ticket/Display.html?id=21185
2301
2302 - getscanline() and setscanline() can now read/write palette index
2303 based data from/to the image for paletted images, by setting type to
2304 'index'.
2305 http://rt.cpan.org/Ticket/Display.html?id=20338
2306
2307 - we no longer hassle you to disable GIF support
2308 http://rt.cpan.org/Ticket/Display.html?id=20687
2309
2310 - minor documentation fixes
2311
2312
2313Imager 0.53 - 26 Jul 2006
2314===========
2315
2316This is a bugfix release.
2317
2318Some test code was left in a code path not covered by the test
2319suite. A test was added to cover this code path and the test code was
2320removed.
2321http://rt.cpan.org/Public/Bug/Display.html?id=20705
2322
2323
2324Imager 0.52 - 25 Jul 2006
2325===========
2326
2327This is primarily a feature release, but contains a fair few bug
2328fixes, new features:
2329
2330 - ability to read and write MS Windows ICO and CUR files
2331
2332 - you can now add file format plugins to support new file formats
2333
2334 - add POD coverage tests
2335
2336 - setcolors() and addcolors() now accept color names and so on
2337 instead of requiring Imager::Color objects.
2338 http://rt.cpan.org/Ticket/Display.html?id=20056
2339
2340 - flood_fill() can now fill to a specified border color instead of
2341 just to the area the same color as the seed.
2342 http://rt.cpan.org/Ticket/Display.html?id=19618
2343
2344
2345Bug fixes:
2346
2347 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2348 calculating the advance width.
2349 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2350
2351 - bounding_box for the T1 driver wasn't including leading and
2352 trailing spaces in the bounding box as the other drivers did, it also
2353 produced strange results for empty strings or strings containing only
2354 spaces
2355
2356 - when reading CMYK jpeg images they were being transferred to the
2357 image object as is, producing a four channel image. It only looked ok
2358 due to an old still unfixed Photoshop bug. We now convert from the
2359 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2360 http://rt.cpan.org/Ticket/Display.html?id=20416
2361
2362 - reading a CYMK TIFF would result in a 4 channel image, reading any
2363 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2364 result in an error.
2365 http://rt.cpan.org/Ticket/Display.html?id=20415
2366
2367 - added /usr/local/include to the default include search path, since
2368 we were already searching /usr/local/lib for libraries.
2369
2370And various minor fixes and documentation updates.
2371
2372
2373Imager 0.51 - 23 Apr 2006

2377 a crash
2378 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2379
2380 - fix mis-processing of the src_maxx and src_maxy parameters of the
2381 paste() method
2382 http://rt.cpan.org/Public/Bug/Display.html?id=18712
2383
2384 - fix a problem in Imager's "smart" handling of the color parameter
2385 to various methods.
2386 http://rt.cpan.org/Public/Bug/Display.html?id=18561
2387

2394 output is an in-memeory buffer.

2396
2397 - fixes an incorrect pointer parameter in the PNG code
2398 http://rt.cpan.org/Public/Bug/Display.html?id=18051
