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.
66
ea3099db
TC
67 - avoid dead code in i_tt_glyph_names(). CID 185321.
68
8b810590
TC
69 - avoid dead code in i_get_anonymous_color_histo(), which is the
70 implementation of getcolorusage(). CID 185327.
71
4eb9a521
TC
72 - avoid dead code in i_ft2_glyph_name(), which is the implementation
73 of glyph_names() for FT2. CID 185342.
74
e7772cea
TC
75 - avoid an unneeded EXTEND() call when the FT2 has_chars()
76 implementation returns 0. CID 185292.
77
596f3eee
TC
78 - the unpack code for ICO/CUR file handling could extend 32-bit
79 unsigned values to 64-bit signed. I believe this is harmless. CID
80 185319.

TC
82Imager 1.008 - 31 Dec 2018
83============
84
75e155e1 85 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
86 This allows file formats that store EXIF data as blobs similarly
87 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 88
b5bbf161 89 - added some more file extensions to image file type mappings
75e155e1
TC
90
91 - added add_type_extensions() class method

107Imager 1.006 - 26 Aug 2017
108============
109
ba7ddbae
TC
110 - the internal i_errors() function now correctly allocates the stack
111 space needed for its result.
112 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
113
114 - t/100-base/020-color.t now uses Imager::Test's test functions
115 instead of its own.
116 https://rt.cpan.org/Ticket/Display.html?id=111993
117
344dda51
TC
118 - write_multi() now returns an error result (a false value) if called
119 with a non-(Imager image object). Previously it would typically
120 crash.
121 https://rt.cpan.org/Ticket/Display.html?id=117878
122
123 - improve the documentation of the jpegquality parameter when
124 writing JPEG files.
125
126 - add code to mitigate CVE-2016-1238, Imager will no longer search the
127 default current directory entry in @INC when searching for file
128 format support modules.

134release 0.55.
135
cd0109d8
TC
136 - revert the ivdformat probes, they don't work as is and trying to
137 fix them is too much work for now.

TC
139Imager 1.004_004 - 15 Apr 2016
140================
141
9c45cc49
TC
142 - test that the ivdformat from Config is correct and look for a valid
143 one if it isn't.
144 For the strange Win32 failures.
145
146 - fix a copy and paste error in pod in samples/samp-form.cgi
147

TC
148Imager 1.004_003 - 23 Mar 2016
149================
150
bd2d657d
TC
151 - add some extra error reporting to the I/O layers tests, this might
152 help catch a failure seen on Win32.

TC
155Imager 1.004_002 - 20 Mar 2016
156================
157
735b3e7b
TC
158 - don't use the seek() method on opened() handles in
159 t/200-file/400-basic.t. In older versions of perl such handles are
160 only IO::Handle objects, not IO::File, and don't have a seek()
161 method.

TC
163Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
164================
165
08914ed1
TC
166 - re-work the t/200-file/400-basic.t to correctly handle failures
167 It's custom ok() function didn't have a prototype and didn't use scalar().
168 This caused ok() to use the note instead of the value being tested when
169 the method called returned an empty list. For an example of the problem
e6226ce5 170 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 171
a2791e47
TC
172 - remove some noise from when Imager tried to work with bugs in old
173 versions of giflib. I can't do much about the new bugs.
08914ed1 174
e6226ce5
TC
175 - the new autolevels filter (Imager 0.99) used an integer for the
176 sample scaling factor which caused the top output level to be too
177 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
178 https://rt.cpan.org/Ticket/Display.html?id=111871
179
e6226ce5 180 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
181 minimum and maximum luminance from the histogram. This slightly
182 reduced the contrast of the output image.
183 https://rt.cpan.org/Ticket/Display.html?id=111871
184
185 - the new autolevels filter now uses a lookup table for 8-bit images
186 to avoid a floating point multiply for each sample.
187 https://rt.cpan.org/Ticket/Display.html?id=111871
188
e6226ce5
TC
189 - fixed several memory leaks detected by valgrind:
190
191 - addcolors() leaked the temporary array of colors supplied to the
192 internal API
193
194 - make_palette() leaked the temporary image array (not the images
195 themselves) passed to the internal API.
196
197 - combine()/i_combine() leaked its working row buffers
198
199 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
200 buffer if there were too many colors
201
202 - getcolorcount()/i_count_colors() leaked the sample buffer if
203 there were too many colors.
204
205 - the nearest_color filter (undocumented until I find a use for it)
206 leaked both temporaries passed to the API and internal buffers
207
a2791e47
TC
208 - the internal process of upgrading a paletted image to a direct
209 color image would leak a context object reference count.
210
211 - a write failure when writing to a GIF file could leak memory.
212
213 - failing to write to a 1-bit/pixel ICO image could leak memory.
214
215 - Imager no longer deliberately leaks the context object from the
216 initial thread. This was done to ensure there was always a context
217 object available, but the code that needed that now handles the
218 lack correctly,
219
e6226ce5
TC
220 - fixed some uninitialized memory usage detected by valgrind:
221
222 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
223 i_matrix_transform_bg() didn't initialize a working color value
224 if there was zero pixel coverage.
225
226 - i_ft2_cp() didn't initialize the complete color when producing an
227 intermediate image. This caused uninitialized value usage when
228 logging the color.

230Imager 1.004 - 8 Nov 2015
231============

TC
233 - Imager::Color::Table is now pre-loaded by the preload() method.
234 https://rt.cpan.org/Ticket/Display.html?id=104896
235
236 - fix an assertion triggered under perl 5.23.4.
237 Thanks to A. Sinan Unur for the report and the patch.
238
7b638aba
TC
239 - Imager->new can now be used to read raw image files.

246Imager 1.003 - 12 May 2015
247============
248
0fda3cfd
TC
249 - update 1.002 release notes to include the center change for filled
250 circle drawing.
251
252 - flood_fill() would escape beyond a 4-connected space under some
253 circumstances.
254 Added many more flood_fill() tests.

TC
257Imager 1.002 - 3 Apr 2015
258============
259
334b8922
TC
260 - drawing anti-aliased filled circles is now 10 to 50 times faster
261 depending on the size of the circle.
0fda3cfd
TC
262 This also changed the center from being the center of the pixel to
263 being the top left of the pixel to match the filled arcs drawn by
264 arc().
334b8922
TC
265 https://rt.cpan.org/Ticket/Display.html?id=101682
266
267 - enhancements to polygon filling:
268
269 - added a mode parameter to control how overlapping regions behave
270
271 - added a polypolygon() method to fill more than one polygon at a
272 time
273
274 - polygon filling is now exposed through the API.
275
45c8e262
TC
276 - added colormodel(), alphachannel() and colorchannels() methods.
277 These were added for two reasons:
278
279 - a future version of Imager may allow the number of channels in
280 an image to not directly represent the color model of an image.
281 eg. a greyscale TIFF image with multiple alpha channels.
282
283 - a future version of Imager may allow an image to be read without
284 translation, for example a TIFF file that contains measurements
0fda3cfd 285 from an instrument. Currently Imager transforms the samples into
d96c4de8 286 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
287 the value back.
288
289 An untranslated image would be unusable as image data, so
290 colormodel() would return "unknown" in this case.
291
292 Similarly a CMYK image might be returned as an "unknown" color
293 model image, if the caller chooses to disable translation to
294 RGB.

327There's nothing special about Imager 1.000, it's just another release.
328
fa3dac1d
TC
329 - fix the skip check for the iolayer qr// buffer test
330

334Imager 0.99_02 - 21 Jul 2014
335==============
336
5dab5b9a
TC
337 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
338 the blue channel in the generated palette, and allow each color
339 component to be in the range 100..255 instead of just 100..254.
340 Thanks to Ralf Neubauer.
341 https://rt.cpan.org/Ticket/Display.html?id=97086
342
343 - revert "improved the XS for i_io_read() and i_io_raw_read()"
344 This caused problems with older perls and didn't provide much of a
345 performance improvement.
346
5bf25bc2 347 - support Inline 0.57 and later.
6d47a6af 348 Inline 0.57 changed the "with" interface.

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

361
362 - GIF: avoid a double-free when do_write() fails.

371Imager 0.99 - 25 Jun 2014
372===========
373
dce1523b
TC
374 - Imager::IO->new_buffer() (and hence Imager->read()'s data
375 parameter) now accepts a reference to a scalar as well as just a
376 plain scalar.
6a160bce 377 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
378
379 - Imager::IO->new_buffer() now always makes a copy of the passed in
380 buffer to avoid problems with temporary objects used for the return
381 value of SvPVbyte().

385 https://rt.cpan.org/Ticket/Display.html?id=92738
386
387 - load plugins from absolute paths on Android
388 Thanks to Brian Fraser.
389 https://rt.cpan.org/Ticket/Display.html?id=93272
390
6a160bce
TC
391 - added the jpeg_optimize parameter for writing JPEG files. This can
392 significantly reduce file sizes, but uses more memory and time.
393 https://rt.cpan.org/Ticket/Display.html?id=94292
394
14fd9e5d
TC
395 - the autolevels filter now works on the luminosity of the image
396 rather then working per channel. The old autolevels filter is
397 still available as "autolevels_skew".
398 https://rt.cpan.org/Ticket/Display.html?id=94413
399
75d54149
TC
400 - Imager::File::PNG now supports libpng 1.6.10.
401 1.6.10 changed CRC errors from benign errors to normal errors,
402 which broke the test which used CRC errors to check for benign
403 error support. Switched to using a 1-bit grey-scale image with a
404 palette to test for benign errors.

407Imager 0.98 - 3 Jan 2014
408===========
409
f84f86a2
TC
410Incompatible changes:
411
412 - the return value of setpixel() has changed.
413
414 Previously the return values for undrawable pixels vs caller errors
415 changed depending on whether you used the multiple pixel calling
416 mechanism, or the single pixel mechanism.
417
418 Now:
419
420 - for an invalid parameter, such as an unknown colour, or missing
421 parameter, an empty list (or undef in scalar context) is
422 returned, and errstr() is set,
423
424 - otherwise the number of pixels drawn is returned. If none of
425 the pixels could be drawn (they were all outside the image), "0
426 but true" is returned.
427
428 https://rt.cpan.org/Ticket/Display.html?id=87650
429
430Other changes:
431
6ba09ab9
TC
432 - when drawing on an image with an alpha channel where the source
433 minimum is greater than zero, Imager would read from beyond the end
434 of a malloc() allocated buffer. In rare circumstances this could
435 lead to some of the source image not being written to the target
436 image, or possibly to a segmentation fault.
437 I don't believe this has any security concerns beyond that.

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

754Other changes:

759 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
760 the API level compiled into a loadable module such as
761 Imager::File::GIF doesn't match that of Imager. Previously it
762 could be difficult to determine exactly which module was failing to
763 load.

TC
784 - when downconverting samples (eg. from floating point to 8 bit)
785 Imager now rounds the sample value rather than attempting to
786 allocate input values over output values equally. The old
787 behaviour had the probably surprising effect of converting a
788 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
789 2.
790 This may result in slightly different 8 or 16-bit output images.
791

TC
792 - BI_BITFIELD BMP images were handled incorrectly, both in
793 incorrectly calculating the space required for the masks and in
794 processing the image data itself.
795 https://rt.cpan.org/Ticket/Display.html?id=76736
796
797 - some odd width BMP BI_RLE4 images use run lengths that run one off
798 the edge of the image. Imager now allows this, discarding the
799 extra column.

817 handle a statically linked libpng.
818 https://rt.cpan.org/Ticket/Display.html?id=74043
819
820 - if a probe includes testcode, Imager::Probe now checks that code as
821 part of the process of checking each configuration rather than as a
822 post test of the found configuration. This allows alternate
823 configurations to be checked if a matching but non-working
824 configuration is found.

900 - setsamples() is now a true complement to getsamples() - it can
901 write 8-bit or floating point samples from a scalar or array
902 reference. This adds i_psamp() and i_psampf() to the C level API.
903
904 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
905 changed to make better use of the typemap, but these aren't part of
906 the perl level API anyway. There were no changes to the C level
907 interfaces to these functions.

1062 - io_glue I/O buffering re-work:
1063
1064 - reorganize io_glue to do it's own buffering by default
1065
1066 - the unbuffered functions are available as i_io_raw_read() (or
1067 raw_read() from perl) etc but are not recommended for typical
1068 use.
1069
1070 - use the new i_io_peekn() when checking for file magic to avoid
1071 seek, allowing Imager to detect the file type and read the file
1072 from an unseekable stream (for formats that don't use random
1073 access)
1074
1075 - added several new I/O layer API functions.
1076
1077 - fix the TGA performance problem, most noticably on Win32
1078 https://rt.cpan.org/Ticket/Display.html?id=70037

1080 - TIFF now uses wrapper functions of the correct types to avoid casts
1081 https://rt.cpan.org/Ticket/Display.html?id=69912
1082
1083 - the callback IO object did its own buffering, controlled by the
1084 maxbuffer parameter supplied to the read() and write() methods.
1085 This buffering has been removed, to avoid redundancy with the
1086 common io_glue buffering. This also avoids a bug in that code
1087 which could rarely pass a zero length to the read callback and
1088 then panic about the result.
1089
1090 - the callback IO object now tests the result of calling the close
1091 callback, which should return true for success.
1092
1093 - the PNM reader did its own buffering. This buffering has been
1094 removed to avoid redundancy with the common io_glue buffering.
1095
1096 - previously the read handlers for fd and callback I/O layers would
1097 call the underlying interface (POSIX read or your supplied callback)
1098 until it filled the buffer. It now only makes one call.
1099
1100 - added public constructors for I/O layer objects (see Imager::IO)
1101
1102 - all core file handlers now use the i_io_foo() wrappers to gain
1103 access to buffered I/O rather than calling the I/O layer
1104 callbacks directly.
1105
1106 - all core file handlers now check for error on close.
1107
1108 - Backward compatibility: if you hava custom file handlers, you can
1109 use i_io_write() etc since they're available as macros in older
1110 versions of Imager.
1111
1112 - eliminate the final remnants of io_glue_commit_types().
1113
1114 - bump IMAGER_API_VERSION, since the above may break assumptions.
1115
1116 - removed the long unused i_gen_reader() and i_gen_writer() utility
1117 functions.

1180Development release as a sanity check for the types re-work.

TC
1181
1182Massive types re-work:
1183
1184 - the type used internally for pixel co-ordinates and image sizes is
1185 now 64-bit on 64-bit platforms (at least sane ones).
1186
1187 - size_t is now used consistently for memory block sizes.
1188
1189 - since this changes the binary interface, the Imager API version has
1190 been incremented. Any module that uses the API will need to be
1191 rebuilt. In most cases that will be enough, but calls to any APIs
1192 that take a pointer to image sizes may need source changes.
1193
1194 - you should be able to create very large images on 64-bit systems,
1195 if you have enough memory. Successfully created a 32768 x 49192 x
1196 3 channel image, filled with a tiled image and scaled it. The
1197 unscaled image was also successfully saved to a JPEG.
1198
1199 - check the image size before attempting to write BMP, GIF, JPEG,
1200 PNG, SGI, TGA, TIFF images.
1201
1202 - correctly handle reading TGA images over 32767 pixels wide or tall.
1203
1204Incidental changes:
1205
1206 - the gif_left and gif_top tags are now clamped to non-negative
1207 values when writing a GIF image.
1208
1209 - removed dead callback read/write code
1210
1211The default maximum memory size when reading files is now 1G.

1832 resulting in a SIGSEGV when attempting to scale an image to a size
1833 too large to fit in memory. This is a NULL pointer access issue,

1849This release primarily contains changes to improve ease of use -
1850rather than you having to convert images to the appropriate number of
1851channels, Imager handles it internally. How to handle drawing colors
1852and the default combine mode is a thornier problem left for some other
1853release.

TC
1858 - moved the imtoc.perl code into Imager::Preprocess
1859
1860 - paste() and rubthrough() now adapt the source image data to the
1861 destination, so you can now safely paste/rubthrough from greyscale
1862 images to color images or back, or from alpha channel images to
1863 noalpha channels or back.
1864 https://rt.cpan.org/Ticket/Display.html?id=30908
1865
1866 - rubthrough() now falls back to pasting when the source doesn't have
1867 an alpha channel. This effectively treats the source as having a
1868 max alpha channel, the right thing to do.
1869 http://rt.cpan.org/Ticket/Display.html?id=29944
1870
1871 - re-worked most of the area filling code to use a common set of
1872 functions when filling.
1873 Corrected normal combine mode.
1874 Rewrote most of the combine modes to match the way the SVG draft
1875 defines them with respect to a translucent source and destination.
1876 Added tests for translucent source and destination.
1877 Added tests to check 8-bit/sample and double/sample combines work
1878 similarly.

1917 - handling of the left-over bit for 16-bit/pixel TGA images has been
1918 changed to match the behaviour of the GIMP. Previously the bit
1919 being set was treated as an opaque pixel, but one user reported a
1920 problem with loading such an image. I haven't been able to find any
1921 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1922 I'll match it's behaviour. See issue 114913 in the GIMP's
1923 bugzilla.

1933 - the old dynaload code used Mach API functions to load dynamic
1934 libraries on Mac OS X. These APIs have been deprecated in OS X
1935 10.5 and were causing some build problems.

2169 - reworked library probing, we can now set more than one probe
2170 function for a library. Disabled the default (non-freetype-config)
2171 library probe and added an extra probe function that searches for
2172 both ft2build.h and whatever it includes, and adds -I as needed.
2173 Hopefully this will fix build problems like

2241Imager 0.55 - 16 Dec 2006
2242===========
2243
2244This is primarily a bug fix release.
2245
2246Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2247
2248There is one new feature:
2249
2250 - the Win32 font driver now supports UTF8 (RT 22166)
2251 http://www.cpanforum.com/threads/3276
2252 http://rt.cpan.org/Ticket/Display.html?id=22166
2253
2254Several bugs were fixed:
2255
2256 - the string() method would not output the string "0"
2257 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2258
2259 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2260 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2261
2262 - the gif_disposal and gif_user_input tags weren't being read from
2263 the file correctly
2264 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2265
2266 - gif.c was failing to build under MSVC
2267 http://rt.cpan.org/Ticket/Display.html?id=23922
2268
2269 - in some cases strings passed to the string() method were treated as
2270 terminated by NUL (chr 0)
2271 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2272
2273 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2274 that's the default build name for zlib on Win32.
2275 http://rt.cpan.org/Ticket/Display.html?id=23064
2276
2277 - search $Config{incpath} for headers too, which we should have been
2278 doing all along.
2279
2280Win32 font driver fixes:
2281
2282 - the global descent value from bounding box was the wrong sign
2283 http://www.cpanforum.com/threads/3276
2284
2285 - if the first or last glyph overflowed the left or right side of the
2286 advance width they would be clipped
2287
2288
2289Imager 0.54 - 14 Sep 2006
2290===========
2291
2292This is primarily a feature release:
2293
2294 - a new qtype value 'mixing' has been added to the scale()
2295 method. This is faster than 'normal', slower than 'preview'. This
2296 is based on the method used by pnmscale, and seems to produce less
2297 blurry results than normal.
2298 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2299
2300 - the rubthrough() method can now render onto images with an alpha
2301 channel.
2302 http://rt.cpan.org/Ticket/Display.html?id=20678
2303
2304 - the read_multi() method now falls back to calling doing a single
2305 image read via the read() method and write_multi() will now fall
2306 back to calling write() if a single image is supplied. This means
2307 you can simply call the read_multi() or write_multi() functions
2308 without having to check if the type is formatted by that method.
2309 http://rt.cpan.org/Ticket/Display.html?id=19457
2310 http://rt.cpan.org/Ticket/Display.html?id=19458
2311
2312 - the GIF loop extension can now be written. If you don't have
2313 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2314 should upgrade.
2315 http://rt.cpan.org/Ticket/Display.html?id=21185
2316
2317 - getscanline() and setscanline() can now read/write palette index
2318 based data from/to the image for paletted images, by setting type to
2319 'index'.
2320 http://rt.cpan.org/Ticket/Display.html?id=20338
2321
2322 - we no longer hassle you to disable GIF support
2323 http://rt.cpan.org/Ticket/Display.html?id=20687
2324
2325 - minor documentation fixes
2326
2327
2328Imager 0.53 - 26 Jul 2006
2329===========
2330
2331This is a bugfix release.
2332
2333Some test code was left in a code path not covered by the test
2334suite. A test was added to cover this code path and the test code was
2335removed.
2336http://rt.cpan.org/Public/Bug/Display.html?id=20705
2337
2338
2339Imager 0.52 - 25 Jul 2006
2340===========
2341
2342This is primarily a feature release, but contains a fair few bug
2343fixes, new features:
2344
2345 - ability to read and write MS Windows ICO and CUR files
2346
2347 - you can now add file format plugins to support new file formats
2348
2349 - add POD coverage tests
2350
2351 - setcolors() and addcolors() now accept color names and so on
2352 instead of requiring Imager::Color objects.
2353 http://rt.cpan.org/Ticket/Display.html?id=20056
2354
2355 - flood_fill() can now fill to a specified border color instead of
2356 just to the area the same color as the seed.
2357 http://rt.cpan.org/Ticket/Display.html?id=19618
2358
2359
2360Bug fixes:
2361
2362 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2363 calculating the advance width.
2364 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2365
2366 - bounding_box for the T1 driver wasn't including leading and
2367 trailing spaces in the bounding box as the other drivers did, it also
2368 produced strange results for empty strings or strings containing only
2369 spaces
2370
2371 - when reading CMYK jpeg images they were being transferred to the
2372 image object as is, producing a four channel image. It only looked ok
2373 due to an old still unfixed Photoshop bug. We now convert from the
2374 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2375 http://rt.cpan.org/Ticket/Display.html?id=20416
2376
2377 - reading a CYMK TIFF would result in a 4 channel image, reading any
2378 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2379 result in an error.
2380 http://rt.cpan.org/Ticket/Display.html?id=20415
2381
2382 - added /usr/local/include to the default include search path, since
2383 we were already searching /usr/local/lib for libraries.
2384
2385And various minor fixes and documentation updates.
2386
2387
2388Imager 0.51 - 23 Apr 2006

2392 a crash
2393 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2394
2395 - fix mis-processing of the src_maxx and src_maxy parameters of the
2396 paste() method
2397 http://rt.cpan.org/Public/Bug/Display.html?id=18712

2399 - fix a problem in Imager's "smart" handling of the color parameter
2400 to various methods.

2402
2403

2408 or 4 channel image to jpeg or a 2 channel image to tga where the
2409 output is an in-memeory buffer.
2410 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2411
2412 - fixes an incorrect pointer parameter in the PNG code
2413 http://rt.cpan.org/Public/Bug/Display.html?id=18051
2414
2415 - skip Inline::C tests when building in a directory with spaces
2416 http://rt.cpan.org/Public/Bug/Display.html?id=18049
