3General changes:
4
5 - to_paletted() and make_palette() now fail (with an error in
6 errstr()) if invalid quantization parameters are supplied.
7
8Coverity finally finished a build[1], fix a few problems:
1791cbdb 9
8445279e
TC
10High severity:
11
1791cbdb 12 - reading a color-mapped TGA file with an id string would cause a
8445279e 13 double-free if the palette was truncated. CID 185317.
1791cbdb 14
6494c395
TC
15 - mixing scaling to sizes where the accumulator row, the working
16 output row or the working input row didn't fit into the address
17 space could result in memory leaks. This can probably only be
8445279e 18 reproduced on very wide floating-point sample images. CID 185318.
6494c395 19
fc24ca5f 20 - convert an array style function parameter pointer to pointer style
3d7b055c 21 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 22 CID 185343.
3d7b055c 23
8445279e 24 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 25
20c297d4 26 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 27 implementation. CID 185303.
20c297d4 28
fc24ca5f 29 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 30 drawing (it should always end up being set.) CID 185341.
fc24ca5f 31
f7675b46 32 - addi style makemap could potentially read one past the end of an
8445279e 33 array. CID 185337.
f7675b46 34
58ec1fde
TC
35 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
36 would result in read beyond the end of the built-in hatch array.
37 Negative values (which Coverity didn't complain about) could also
8445279e 38 cause problems. CID 185331.
58ec1fde 39
b7346865
TC
40 - the Imager::Color set_internal() interal method no longer
41 calls the over-complicated ICL_set_internal() (which is retained
42 only for the old API.) Coverity complained that this leaked, but
43 this could only occur with an invalid (NULL pointer) color object.
8445279e 44 CID 185323.
b7346865 45
785364c1
TC
46 - the underlying implementation of the map() method could read before
47 the beginning on an allocated array if supplied with inconsistent
48 parameters, which Coverity complained about. No Imager code calls
49 that function with inconsistent parameters, but a
8445279e 50 belt-and-suspenders check was added. CID 185315.
785364c1 51
eb7e48c9
TC
52 - Coverity complained a call to i_getcolors(), used by the
53 implementation of the is_bilevel() method could leave the fetched
8445279e 54 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 55
c1c8b1e9
TC
56 - a numeric combining mode of 13 (eg. as a parameter to
57 Imager::Fill->new())could cause an invalid array read in
58 i_get_combine() due to a fencepost error in validating the combine
8445279e 59 number. CID 185299.
c1c8b1e9 60
c4fd43be
TC
61
62
63 - avoid an unneeded EXTEND() call when the FT1 has_chars()
64 implementation returns 0. CID 185350.
65
66 - avoid accessing a possibly NULL map from MakeMapObject() in a
67 logging call. (GIF) CID 185296.
68
4615ad8d
TC
69 - gradgen() allocated the wrong amount of space (always too much) for
70 the color array. CID 185291.
71
ea3099db
TC
72 - avoid dead code in i_tt_glyph_names(). CID 185321.
73
8b810590
TC
74 - avoid dead code in i_get_anonymous_color_histo(), which is the
75 implementation of getcolorusage(). CID 185327.
76
4eb9a521
TC
77 - avoid dead code in i_ft2_glyph_name(), which is the implementation
78 of glyph_names() for FT2. CID 185342.
79
c028aa12
TC
80 - avoid dead code in i_t1_glyph_names(), which is the implementation
81 of glyph_names() for T1. CID 185322.
82
e7772cea
TC
83 - avoid an unneeded EXTEND() call when the FT2 has_chars()
84 implementation returns 0. CID 185292.
85
596f3eee
TC
86 - the unpack code for ICO/CUR file handling could extend 32-bit
87 unsigned values to 64-bit signed. I believe this is harmless. CID
88 185319.
89
a2ca2b80
TC
90 - remove an unneeded check when terminating the stream for JPEG
91 writing. CID 185347.
92
56ce7446
TC
93 - skip an unneeded check when freeing the combine temp buffer in the
94 fountain filter. CID 185286.
95
96 - check the combine function pointer consistently rather than the
97 combine code in one place in the fountain filter.
98
a3b721bb
TC
99 - error diffusion now validates a custom error diffusion map and reports
100 an error if it's bad. CID 185288.
101
102[1] The first two build submissions ended up at the end of a ~400
103build queue, and seemed to have been cancelled by Coverity. A build
104submitted on NYE went through in minutes.

106Imager 1.008 - 31 Dec 2018
107============
108
75e155e1 109 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
110 This allows file formats that store EXIF data as blobs similarly
111 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 112
b5bbf161 113 - added some more file extensions to image file type mappings
75e155e1
TC
114
115 - added add_type_extensions() class method

131Imager 1.006 - 26 Aug 2017
132============
133

TC
134 - the internal i_errors() function now correctly allocates the stack
135 space needed for its result.
136 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
137
138 - t/100-base/020-color.t now uses Imager::Test's test functions
139 instead of its own.
140 https://rt.cpan.org/Ticket/Display.html?id=111993
141
344dda51
TC
142 - write_multi() now returns an error result (a false value) if called
143 with a non-(Imager image object). Previously it would typically
144 crash.
145 https://rt.cpan.org/Ticket/Display.html?id=117878
146
147 - improve the documentation of the jpegquality parameter when
148 writing JPEG files.

158release 0.55.
159
cd0109d8
TC
160 - revert the ivdformat probes, they don't work as is and trying to
161 fix them is too much work for now.

TC
163Imager 1.004_004 - 15 Apr 2016
164================
165
9c45cc49
TC
166 - test that the ivdformat from Config is correct and look for a valid
167 one if it isn't.
168 For the strange Win32 failures.
169
170 - fix a copy and paste error in pod in samples/samp-form.cgi

172Imager 1.004_003 - 23 Mar 2016
173================
174
bd2d657d
TC
175 - add some extra error reporting to the I/O layers tests, this might
176 help catch a failure seen on Win32.

179Imager 1.004_002 - 20 Mar 2016
180================
181
735b3e7b
TC
182 - don't use the seek() method on opened() handles in
183 t/200-file/400-basic.t. In older versions of perl such handles are
184 only IO::Handle objects, not IO::File, and don't have a seek()
185 method.

187Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
188================
189
08914ed1
TC
190 - re-work the t/200-file/400-basic.t to correctly handle failures
191 It's custom ok() function didn't have a prototype and didn't use scalar().
192 This caused ok() to use the note instead of the value being tested when
193 the method called returned an empty list. For an example of the problem
e6226ce5 194 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 195
a2791e47
TC
196 - remove some noise from when Imager tried to work with bugs in old
197 versions of giflib. I can't do much about the new bugs.
08914ed1 198
e6226ce5
TC
199 - the new autolevels filter (Imager 0.99) used an integer for the
200 sample scaling factor which caused the top output level to be too
201 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
202 https://rt.cpan.org/Ticket/Display.html?id=111871
203
e6226ce5 204 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
205 minimum and maximum luminance from the histogram. This slightly
206 reduced the contrast of the output image.
207 https://rt.cpan.org/Ticket/Display.html?id=111871
208
209 - the new autolevels filter now uses a lookup table for 8-bit images
210 to avoid a floating point multiply for each sample.
211 https://rt.cpan.org/Ticket/Display.html?id=111871
212
e6226ce5
TC
213 - fixed several memory leaks detected by valgrind:
214
215 - addcolors() leaked the temporary array of colors supplied to the
216 internal API
217
218 - make_palette() leaked the temporary image array (not the images
219 themselves) passed to the internal API.
220
221 - combine()/i_combine() leaked its working row buffers
222
223 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
224 buffer if there were too many colors
225
226 - getcolorcount()/i_count_colors() leaked the sample buffer if
227 there were too many colors.
228
229 - the nearest_color filter (undocumented until I find a use for it)
230 leaked both temporaries passed to the API and internal buffers
231
a2791e47
TC
232 - the internal process of upgrading a paletted image to a direct
233 color image would leak a context object reference count.
234
235 - a write failure when writing to a GIF file could leak memory.
236
237 - failing to write to a 1-bit/pixel ICO image could leak memory.
238
239 - Imager no longer deliberately leaks the context object from the
240 initial thread. This was done to ensure there was always a context
241 object available, but the code that needed that now handles the
242 lack correctly,
243
e6226ce5
TC
244 - fixed some uninitialized memory usage detected by valgrind:
245
246 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
247 i_matrix_transform_bg() didn't initialize a working color value
248 if there was zero pixel coverage.
249
250 - i_ft2_cp() didn't initialize the complete color when producing an
251 intermediate image. This caused uninitialized value usage when
252 logging the color.

TC
273 - update 1.002 release notes to include the center change for filled
274 circle drawing.
275
276 - flood_fill() would escape beyond a 4-connected space under some
277 circumstances.
278 Added many more flood_fill() tests.

281Imager 1.002 - 3 Apr 2015
282============
283
334b8922
TC
284 - drawing anti-aliased filled circles is now 10 to 50 times faster
285 depending on the size of the circle.
0fda3cfd
TC
286 This also changed the center from being the center of the pixel to
287 being the top left of the pixel to match the filled arcs drawn by
288 arc().
334b8922
TC
289 https://rt.cpan.org/Ticket/Display.html?id=101682
290
291 - enhancements to polygon filling:
292
293 - added a mode parameter to control how overlapping regions behave
294
295 - added a polypolygon() method to fill more than one polygon at a
296 time
297
298 - polygon filling is now exposed through the API.
299
45c8e262
TC
300 - added colormodel(), alphachannel() and colorchannels() methods.
301 These were added for two reasons:
302
303 - a future version of Imager may allow the number of channels in
304 an image to not directly represent the color model of an image.
305 eg. a greyscale TIFF image with multiple alpha channels.
306
307 - a future version of Imager may allow an image to be read without
308 translation, for example a TIFF file that contains measurements
0fda3cfd 309 from an instrument. Currently Imager transforms the samples into
d96c4de8 310 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
311 the value back.
312
313 An untranslated image would be unusable as image data, so
314 colormodel() would return "unknown" in this case.
315
316 Similarly a CMYK image might be returned as an "unknown" color
317 model image, if the caller chooses to disable translation to
318 RGB.

TC
361 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
362 the blue channel in the generated palette, and allow each color
363 component to be in the range 100..255 instead of just 100..254.
364 Thanks to Ralf Neubauer.

366
367 - revert "improved the XS for i_io_read() and i_io_raw_read()"
368 This caused problems with older perls and didn't provide much of a
369 performance improvement.
370

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

TC
415 - added the jpeg_optimize parameter for writing JPEG files. This can
416 significantly reduce file sizes, but uses more memory and time.
417 https://rt.cpan.org/Ticket/Display.html?id=94292
418
14fd9e5d
TC
419 - the autolevels filter now works on the luminosity of the image
420 rather then working per channel. The old autolevels filter is
421 still available as "autolevels_skew".
422 https://rt.cpan.org/Ticket/Display.html?id=94413
423
75d54149
TC
424 - Imager::File::PNG now supports libpng 1.6.10.
425 1.6.10 changed CRC errors from benign errors to normal errors,
426 which broke the test which used CRC errors to check for benign
427 error support. Switched to using a 1-bit grey-scale image with a
428 palette to test for benign errors.

436 - the return value of setpixel() has changed.
437
438 Previously the return values for undrawable pixels vs caller errors
439 changed depending on whether you used the multiple pixel calling
440 mechanism, or the single pixel mechanism.
441
442 Now:
443
444 - for an invalid parameter, such as an unknown colour, or missing
445 parameter, an empty list (or undef in scalar context) is
446 returned, and errstr() is set,
447
448 - otherwise the number of pixels drawn is returned. If none of
449 the pixels could be drawn (they were all outside the image), "0
450 but true" is returned.

TC
456 - when drawing on an image with an alpha channel where the source
457 minimum is greater than zero, Imager would read from beyond the end
458 of a malloc() allocated buffer. In rare circumstances this could
459 lead to some of the source image not being written to the target
460 image, or possibly to a segmentation fault.
461 I don't believe this has any security concerns beyond that.
462

TC
463 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
464 text drawn would be nonsense. This would also read beyond the end
465 of a malloced buffer.

516 Mixed SampleFormat are handled incorrectly, since libtiff returns

770 matrix_transform() for 1 and 3 channel 8-bit images.
771 Adjusted the two tranlate matrices used to build the final rotation
772 matrix to use the distance between the outlier pixels rather than
773 the pixel dimensions (ie. dimension-1).
774 With all of this the output of rotate(degrees => 270) on an 8-bit

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

TC
808 - when downconverting samples (eg. from floating point to 8 bit)
809 Imager now rounds the sample value rather than attempting to
810 allocate input values over output values equally. The old
811 behaviour had the probably surprising effect of converting a
812 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
813 2.
814 This may result in slightly different 8 or 16-bit output images.

TC
816 - BI_BITFIELD BMP images were handled incorrectly, both in

841 handle a statically linked libpng.
842 https://rt.cpan.org/Ticket/Display.html?id=74043
843
844 - if a probe includes testcode, Imager::Probe now checks that code as
845 part of the process of checking each configuration rather than as a
846 post test of the found configuration. This allows alternate
847 configurations to be checked if a matching but non-working
848 configuration is found.

897 - Imager (and the bundled dynamic modules) no longer fallback to

TC
924 - setsamples() is now a true complement to getsamples() - it can
925 write 8-bit or floating point samples from a scalar or array
926 reference. This adds i_psamp() and i_psampf() to the C level API.
927
928 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
929 changed to make better use of the typemap, but these aren't part of
930 the perl level API anyway. There were no changes to the C level
931 interfaces to these functions.

1086 - io_glue I/O buffering re-work:
1087
1088 - reorganize io_glue to do it's own buffering by default
1089
1090 - the unbuffered functions are available as i_io_raw_read() (or
1091 raw_read() from perl) etc but are not recommended for typical
1092 use.
1093
1094 - use the new i_io_peekn() when checking for file magic to avoid
1095 seek, allowing Imager to detect the file type and read the file
1096 from an unseekable stream (for formats that don't use random
1097 access)
1098
1099 - added several new I/O layer API functions.
1100
1101 - fix the TGA performance problem, most noticably on Win32
1102 https://rt.cpan.org/Ticket/Display.html?id=70037
1103
1104 - TIFF now uses wrapper functions of the correct types to avoid casts
1105 https://rt.cpan.org/Ticket/Display.html?id=69912
1106
1107 - the callback IO object did its own buffering, controlled by the
1108 maxbuffer parameter supplied to the read() and write() methods.
1109 This buffering has been removed, to avoid redundancy with the
1110 common io_glue buffering. This also avoids a bug in that code
1111 which could rarely pass a zero length to the read callback and
1112 then panic about the result.
1113
1114 - the callback IO object now tests the result of calling the close
1115 callback, which should return true for success.
1116
1117 - the PNM reader did its own buffering. This buffering has been
1118 removed to avoid redundancy with the common io_glue buffering.
1119
1120 - previously the read handlers for fd and callback I/O layers would
1121 call the underlying interface (POSIX read or your supplied callback)
1122 until it filled the buffer. It now only makes one call.
1123
1124 - added public constructors for I/O layer objects (see Imager::IO)
1125
1126 - all core file handlers now use the i_io_foo() wrappers to gain
1127 access to buffered I/O rather than calling the I/O layer
1128 callbacks directly.
1129
1130 - all core file handlers now check for error on close.
1131
1132 - Backward compatibility: if you hava custom file handlers, you can
1133 use i_io_write() etc since they're available as macros in older
1134 versions of Imager.
1135
1136 - eliminate the final remnants of io_glue_commit_types().
1137
1138 - bump IMAGER_API_VERSION, since the above may break assumptions.
1139
1140 - removed the long unused i_gen_reader() and i_gen_writer() utility
1141 functions.

1149 dimensions and co-ordinated, and for memory block sizes.
1150
1151 - handle IFD loops in TIFF files correctly. Previously this would
1152 lead to an infinite loop.

1204Development release as a sanity check for the types re-work.
8d14daab
TC
1205
1206Massive types re-work:
1207
1208 - the type used internally for pixel co-ordinates and image sizes is
1209 now 64-bit on 64-bit platforms (at least sane ones).
1210
1211 - size_t is now used consistently for memory block sizes.
1212
1213 - since this changes the binary interface, the Imager API version has
1214 been incremented. Any module that uses the API will need to be
1215 rebuilt. In most cases that will be enough, but calls to any APIs
1216 that take a pointer to image sizes may need source changes.
1217
1218 - you should be able to create very large images on 64-bit systems,
1219 if you have enough memory. Successfully created a 32768 x 49192 x
1220 3 channel image, filled with a tiled image and scaled it. The
1221 unscaled image was also successfully saved to a JPEG.
1222
1223 - check the image size before attempting to write BMP, GIF, JPEG,
1224 PNG, SGI, TGA, TIFF images.
1225
1226 - correctly handle reading TGA images over 32767 pixels wide or tall.
1227
1228Incidental changes:
1229
1230 - the gif_left and gif_top tags are now clamped to non-negative
1231 values when writing a GIF image.
1232
1233 - removed dead callback read/write code
1234
1235The default maximum memory size when reading files is now 1G.

1873This release primarily contains changes to improve ease of use -
1874rather than you having to convert images to the appropriate number of
1875channels, Imager handles it internally. How to handle drawing colors
1876and the default combine mode is a thornier problem left for some other
1877release.

TC
1882 - moved the imtoc.perl code into Imager::Preprocess
1883
1884 - paste() and rubthrough() now adapt the source image data to the
1885 destination, so you can now safely paste/rubthrough from greyscale
1886 images to color images or back, or from alpha channel images to
1887 noalpha channels or back.
1888 https://rt.cpan.org/Ticket/Display.html?id=30908
1889
1890 - rubthrough() now falls back to pasting when the source doesn't have
1891 an alpha channel. This effectively treats the source as having a
1892 max alpha channel, the right thing to do.
1893 http://rt.cpan.org/Ticket/Display.html?id=29944
1894
1895 - re-worked most of the area filling code to use a common set of
1896 functions when filling.
1897 Corrected normal combine mode.
1898 Rewrote most of the combine modes to match the way the SVG draft
1899 defines them with respect to a translucent source and destination.
1900 Added tests for translucent source and destination.
1901 Added tests to check 8-bit/sample and double/sample combines work
1902 similarly.

1941 - handling of the left-over bit for 16-bit/pixel TGA images has been
1942 changed to match the behaviour of the GIMP. Previously the bit
1943 being set was treated as an opaque pixel, but one user reported a
1944 problem with loading such an image. I haven't been able to find any
1945 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1946 I'll match it's behaviour. See issue 114913 in the GIMP's
1947 bugzilla.

1957 - the old dynaload code used Mach API functions to load dynamic
1958 libraries on Mac OS X. These APIs have been deprecated in OS X

2193 - reworked library probing, we can now set more than one probe
2194 function for a library. Disabled the default (non-freetype-config)
2195 library probe and added an extra probe function that searches for
2196 both ft2build.h and whatever it includes, and adds -I as needed.
2197 Hopefully this will fix build problems like

2265Imager 0.55 - 16 Dec 2006
2266===========
2267
2268This is primarily a bug fix release.
2269
2270Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2271
2272There is one new feature:
2273
2274 - the Win32 font driver now supports UTF8 (RT 22166)
2275 http://www.cpanforum.com/threads/3276
2276 http://rt.cpan.org/Ticket/Display.html?id=22166
2277
2278Several bugs were fixed:
2279
2280 - the string() method would not output the string "0"
2281 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2282
2283 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2284 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2285
2286 - the gif_disposal and gif_user_input tags weren't being read from
2287 the file correctly
2288 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2289
2290 - gif.c was failing to build under MSVC
2291 http://rt.cpan.org/Ticket/Display.html?id=23922
2292
2293 - in some cases strings passed to the string() method were treated as
2294 terminated by NUL (chr 0)
2295 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2296
2297 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2298 that's the default build name for zlib on Win32.
2299 http://rt.cpan.org/Ticket/Display.html?id=23064
2300
2301 - search $Config{incpath} for headers too, which we should have been
2302 doing all along.
2303
2304Win32 font driver fixes:
2305
2306 - the global descent value from bounding box was the wrong sign
2307 http://www.cpanforum.com/threads/3276
2308
2309 - if the first or last glyph overflowed the left or right side of the
2310 advance width they would be clipped
2311
2312
2313Imager 0.54 - 14 Sep 2006
2314===========
2315
2316This is primarily a feature release:
2317
2318 - a new qtype value 'mixing' has been added to the scale()
2319 method. This is faster than 'normal', slower than 'preview'. This
2320 is based on the method used by pnmscale, and seems to produce less
2321 blurry results than normal.
2322 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2323
2324 - the rubthrough() method can now render onto images with an alpha
2325 channel.
2326 http://rt.cpan.org/Ticket/Display.html?id=20678
2327
2328 - the read_multi() method now falls back to calling doing a single
2329 image read via the read() method and write_multi() will now fall
2330 back to calling write() if a single image is supplied. This means
2331 you can simply call the read_multi() or write_multi() functions
2332 without having to check if the type is formatted by that method.
2333 http://rt.cpan.org/Ticket/Display.html?id=19457
2334 http://rt.cpan.org/Ticket/Display.html?id=19458
2335
2336 - the GIF loop extension can now be written. If you don't have
2337 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2338 should upgrade.
2339 http://rt.cpan.org/Ticket/Display.html?id=21185
2340
2341 - getscanline() and setscanline() can now read/write palette index
2342 based data from/to the image for paletted images, by setting type to
2343 'index'.
2344 http://rt.cpan.org/Ticket/Display.html?id=20338
2345
2346 - we no longer hassle you to disable GIF support
2347 http://rt.cpan.org/Ticket/Display.html?id=20687
2348
2349 - minor documentation fixes
2350
2351
2352Imager 0.53 - 26 Jul 2006
2353===========
2354
2355This is a bugfix release.
2356
2357Some test code was left in a code path not covered by the test
2358suite. A test was added to cover this code path and the test code was
2359removed.
2360http://rt.cpan.org/Public/Bug/Display.html?id=20705
2361
2362
2363Imager 0.52 - 25 Jul 2006
2364===========
2365
2366This is primarily a feature release, but contains a fair few bug
2367fixes, new features:
2368
2369 - ability to read and write MS Windows ICO and CUR files
2370
2371 - you can now add file format plugins to support new file formats
2372
2373 - add POD coverage tests
2374
2375 - setcolors() and addcolors() now accept color names and so on
2376 instead of requiring Imager::Color objects.
2377 http://rt.cpan.org/Ticket/Display.html?id=20056
2378
2379 - flood_fill() can now fill to a specified border color instead of
2380 just to the area the same color as the seed.
2381 http://rt.cpan.org/Ticket/Display.html?id=19618
2382
2383
2384Bug fixes:
2385
2386 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2387 calculating the advance width.
2388 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2389
2390 - bounding_box for the T1 driver wasn't including leading and
2391 trailing spaces in the bounding box as the other drivers did, it also
2392 produced strange results for empty strings or strings containing only
2393 spaces
2394
2395 - when reading CMYK jpeg images they were being transferred to the
2396 image object as is, producing a four channel image. It only looked ok
2397 due to an old still unfixed Photoshop bug. We now convert from the
2398 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2399 http://rt.cpan.org/Ticket/Display.html?id=20416
2400
2401 - reading a CYMK TIFF would result in a 4 channel image, reading any
2402 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2403 result in an error.
2404 http://rt.cpan.org/Ticket/Display.html?id=20415
2405
2406 - added /usr/local/include to the default include search path, since
2407 we were already searching /usr/local/lib for libraries.
2408
2409And various minor fixes and documentation updates.
2410
2411

2416 a crash
2417 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2418
2419 - fix mis-processing of the src_maxx and src_maxy parameters of the
2420 paste() method
2421 http://rt.cpan.org/Public/Bug/Display.html?id=18712
2422
2423 - fix a problem in Imager's "smart" handling of the color parameter

2432 or 4 channel image to jpeg or a 2 channel image to tga where the
2433 output is an in-memeory buffer.
2434 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2435
2436 - fixes an incorrect pointer parameter in the PNG code
2437 http://rt.cpan.org/Public/Bug/Display.html?id=18051
