3General changes:
4
5 - to_paletted() and make_palette() now fail (with an error in
6 errstr()) if invalid quantization parameters are supplied.
7
35ec3a87
TC
8 - map() would corrupt a channel if there was a gap in the arrayref of
9 channels. Detected by Coverity. CID 185300.
10
a3b721bb 11Coverity finally finished a build[1], fix a few problems:
1791cbdb 12
8445279e
TC
13High severity:
14
1791cbdb 15 - reading a color-mapped TGA file with an id string would cause a
8445279e 16 double-free if the palette was truncated. CID 185317.
1791cbdb 17
6494c395
TC
18 - mixing scaling to sizes where the accumulator row, the working
19 output row or the working input row didn't fit into the address
20 space could result in memory leaks. This can probably only be
8445279e 21 reproduced on very wide floating-point sample images. CID 185318.
6494c395 22
fc24ca5f 23 - convert an array style function parameter pointer to pointer style
3d7b055c 24 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 25 CID 185343.
3d7b055c 26
8445279e 27 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 28
20c297d4 29 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 30 implementation. CID 185303.
20c297d4 31
fc24ca5f 32 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 33 drawing (it should always end up being set.) CID 185341.
fc24ca5f 34
f7675b46 35 - addi style makemap could potentially read one past the end of an
8445279e 36 array. CID 185337.
f7675b46 37
58ec1fde
TC
38 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
39 would result in read beyond the end of the built-in hatch array.
40 Negative values (which Coverity didn't complain about) could also
8445279e 41 cause problems. CID 185331.
58ec1fde 42
b7346865
TC
43 - the Imager::Color set_internal() interal method no longer
44 calls the over-complicated ICL_set_internal() (which is retained
45 only for the old API.) Coverity complained that this leaked, but
46 this could only occur with an invalid (NULL pointer) color object.
8445279e 47 CID 185323.
b7346865 48
785364c1
TC
49 - the underlying implementation of the map() method could read before
50 the beginning on an allocated array if supplied with inconsistent
51 parameters, which Coverity complained about. No Imager code calls
52 that function with inconsistent parameters, but a
8445279e 53 belt-and-suspenders check was added. CID 185315.
785364c1 54
eb7e48c9
TC
55 - Coverity complained a call to i_getcolors(), used by the
56 implementation of the is_bilevel() method could leave the fetched
8445279e 57 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 58
c1c8b1e9
TC
59 - a numeric combining mode of 13 (eg. as a parameter to
60 Imager::Fill->new())could cause an invalid array read in
61 i_get_combine() due to a fencepost error in validating the combine
8445279e 62 number. CID 185299.
c1c8b1e9 63
c4fd43be
TC
64
65
66 - avoid an unneeded EXTEND() call when the FT1 has_chars()
67 implementation returns 0. CID 185350.
68
69 - avoid accessing a possibly NULL map from MakeMapObject() in a
70 logging call. (GIF) CID 185296.
71
4615ad8d
TC
72 - gradgen() allocated the wrong amount of space (always too much) for
73 the color array. CID 185291.
74
ea3099db
TC
75 - avoid dead code in i_tt_glyph_names(). CID 185321.
76
8b810590
TC
77 - avoid dead code in i_get_anonymous_color_histo(), which is the
78 implementation of getcolorusage(). CID 185327.
79
4eb9a521
TC
80 - avoid dead code in i_ft2_glyph_name(), which is the implementation
81 of glyph_names() for FT2. CID 185342.
82
c028aa12
TC
83 - avoid dead code in i_t1_glyph_names(), which is the implementation
84 of glyph_names() for T1. CID 185322.
85
e7772cea
TC
86 - avoid an unneeded EXTEND() call when the FT2 has_chars()
87 implementation returns 0. CID 185292.
88
596f3eee
TC
89 - the unpack code for ICO/CUR file handling could extend 32-bit
90 unsigned values to 64-bit signed. I believe this is harmless. CID
91 185319.
92
a2ca2b80
TC
93 - remove an unneeded check when terminating the stream for JPEG
94 writing. CID 185347.
95
56ce7446
TC
96 - skip an unneeded check when freeing the combine temp buffer in the
97 fountain filter. CID 185286.
98
99 - check the combine function pointer consistently rather than the
100 combine code in one place in the fountain filter.
101
a3b721bb
TC
102 - error diffusion now validates a custom error diffusion map and reports
103 an error if it's bad. CID 185288.
104
215d9ead
TC
105 - avoid discarding the value of i_io_getc() when scanning numbers in
106 pnm.c. CID 185293.
107
9ca939d0
TC
108 - handle failure to clone the log filehandle when cloning the Imager
109 context object on thread creation. CID 185294.
110
70501294
TC
111 - fix an unsigned comparison when converting character code to a
112 glyph index with a NULL character map. This should be rare. CID
113 185297.
114
6fa51f9c
TC
115 - i_img_info() (C API) no longer tries to handle a NULL image object
116 pointer. CID 185298.

118[1] The first two build submissions ended up at the end of a ~400

122Imager 1.008 - 31 Dec 2018
123============
124
75e155e1 125 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
126 This allows file formats that store EXIF data as blobs similarly
127 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 128
b5bbf161 129 - added some more file extensions to image file type mappings
75e155e1
TC
130
131 - added add_type_extensions() class method

147Imager 1.006 - 26 Aug 2017
148============
149
ba7ddbae
TC
150 - the internal i_errors() function now correctly allocates the stack
151 space needed for its result.
152 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
153
154 - t/100-base/020-color.t now uses Imager::Test's test functions
155 instead of its own.
156 https://rt.cpan.org/Ticket/Display.html?id=111993
157
344dda51
TC
158 - write_multi() now returns an error result (a false value) if called
159 with a non-(Imager image object). Previously it would typically
160 crash.
161 https://rt.cpan.org/Ticket/Display.html?id=117878
162
163 - improve the documentation of the jpegquality parameter when
164 writing JPEG files.
165
166 - add code to mitigate CVE-2016-1238, Imager will no longer search the
167 default current directory entry in @INC when searching for file
168 format support modules.

174release 0.55.
175
cd0109d8

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

TC
179Imager 1.004_004 - 15 Apr 2016
180================
181
9c45cc49
TC
182 - test that the ivdformat from Config is correct and look for a valid
183 one if it isn't.
184 For the strange Win32 failures.
185
186 - fix a copy and paste error in pod in samples/samp-form.cgi

TC
188Imager 1.004_003 - 23 Mar 2016
189================
190
bd2d657d
TC
191 - add some extra error reporting to the I/O layers tests, this might
192 help catch a failure seen on Win32.

195Imager 1.004_002 - 20 Mar 2016
196================
197
735b3e7b
TC
198 - don't use the seek() method on opened() handles in
199 t/200-file/400-basic.t. In older versions of perl such handles are
200 only IO::Handle objects, not IO::File, and don't have a seek()
201 method.

203Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
204================
205
08914ed1
TC
206 - re-work the t/200-file/400-basic.t to correctly handle failures
207 It's custom ok() function didn't have a prototype and didn't use scalar().
208 This caused ok() to use the note instead of the value being tested when
209 the method called returned an empty list. For an example of the problem
e6226ce5 210 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 211
a2791e47
TC
212 - remove some noise from when Imager tried to work with bugs in old
213 versions of giflib. I can't do much about the new bugs.
08914ed1 214
e6226ce5
TC
215 - the new autolevels filter (Imager 0.99) used an integer for the
216 sample scaling factor which caused the top output level to be too
217 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
218 https://rt.cpan.org/Ticket/Display.html?id=111871
219
e6226ce5 220 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
221 minimum and maximum luminance from the histogram. This slightly
222 reduced the contrast of the output image.
223 https://rt.cpan.org/Ticket/Display.html?id=111871
224
225 - the new autolevels filter now uses a lookup table for 8-bit images
226 to avoid a floating point multiply for each sample.
227 https://rt.cpan.org/Ticket/Display.html?id=111871
228
e6226ce5
TC
229 - fixed several memory leaks detected by valgrind:
230
231 - addcolors() leaked the temporary array of colors supplied to the
232 internal API
233
234 - make_palette() leaked the temporary image array (not the images
235 themselves) passed to the internal API.
236
237 - combine()/i_combine() leaked its working row buffers
238
239 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
240 buffer if there were too many colors
241
242 - getcolorcount()/i_count_colors() leaked the sample buffer if
243 there were too many colors.
244
245 - the nearest_color filter (undocumented until I find a use for it)
246 leaked both temporaries passed to the API and internal buffers
247
a2791e47
TC
248 - the internal process of upgrading a paletted image to a direct
249 color image would leak a context object reference count.
250
251 - a write failure when writing to a GIF file could leak memory.
252
253 - failing to write to a 1-bit/pixel ICO image could leak memory.
254
255 - Imager no longer deliberately leaks the context object from the
256 initial thread. This was done to ensure there was always a context
257 object available, but the code that needed that now handles the
258 lack correctly,
259
e6226ce5
TC
260 - fixed some uninitialized memory usage detected by valgrind:
261
262 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
263 i_matrix_transform_bg() didn't initialize a working color value
264 if there was zero pixel coverage.
265
266 - i_ft2_cp() didn't initialize the complete color when producing an
267 intermediate image. This caused uninitialized value usage when
268 logging the color.

275
276 - fix an assertion triggered under perl 5.23.4.
277 Thanks to A. Sinan Unur for the report and the patch.

286Imager 1.003 - 12 May 2015
287============
288
0fda3cfd
TC
289 - update 1.002 release notes to include the center change for filled
290 circle drawing.
291
292 - flood_fill() would escape beyond a 4-connected space under some
293 circumstances.
294 Added many more flood_fill() tests.

TC
297Imager 1.002 - 3 Apr 2015
298============
299
334b8922
TC
300 - drawing anti-aliased filled circles is now 10 to 50 times faster
301 depending on the size of the circle.
0fda3cfd
TC
302 This also changed the center from being the center of the pixel to
303 being the top left of the pixel to match the filled arcs drawn by
304 arc().
334b8922
TC
305 https://rt.cpan.org/Ticket/Display.html?id=101682
306
307 - enhancements to polygon filling:
308
309 - added a mode parameter to control how overlapping regions behave
310
311 - added a polypolygon() method to fill more than one polygon at a
312 time
313
314 - polygon filling is now exposed through the API.
315
45c8e262
TC
316 - added colormodel(), alphachannel() and colorchannels() methods.
317 These were added for two reasons:
318
319 - a future version of Imager may allow the number of channels in
320 an image to not directly represent the color model of an image.
321 eg. a greyscale TIFF image with multiple alpha channels.
322
323 - a future version of Imager may allow an image to be read without
324 translation, for example a TIFF file that contains measurements
0fda3cfd 325 from an instrument. Currently Imager transforms the samples into
d96c4de8 326 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
327 the value back.
328
329 An untranslated image would be unusable as image data, so
330 colormodel() would return "unknown" in this case.
331
332 Similarly a CMYK image might be returned as an "unknown" color
333 model image, if the caller chooses to disable translation to
334 RGB.

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

TC
414 - Imager::IO->new_buffer() (and hence Imager->read()'s data
415 parameter) now accepts a reference to a scalar as well as just a

440 - Imager::File::PNG now supports libpng 1.6.10.
441 1.6.10 changed CRC errors from benign errors to normal errors,
442 which broke the test which used CRC errors to check for benign
443 error support. Switched to using a 1-bit grey-scale image with a
444 palette to test for benign errors.

450Incompatible changes:
451
452 - the return value of setpixel() has changed.
453
454 Previously the return values for undrawable pixels vs caller errors
455 changed depending on whether you used the multiple pixel calling
456 mechanism, or the single pixel mechanism.
457
458 Now:
459
460 - for an invalid parameter, such as an unknown colour, or missing
461 parameter, an empty list (or undef in scalar context) is
462 returned, and errstr() is set,
463
464 - otherwise the number of pixels drawn is returned. If none of
465 the pixels could be drawn (they were all outside the image), "0
466 but true" is returned.

470Other changes:

TC
472 - when drawing on an image with an alpha channel where the source
473 minimum is greater than zero, Imager would read from beyond the end
474 of a malloc() allocated buffer. In rare circumstances this could
475 lead to some of the source image not being written to the target
476 image, or possibly to a segmentation fault.
477 I don't believe this has any security concerns beyond that.
478
0d052fd9
TC
479 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
480 text drawn would be nonsense. This would also read beyond the end
481 of a malloced buffer.
482

532 Mixed SampleFormat are handled incorrectly, since libtiff returns

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

800 the API level compiled into a loadable module such as
801 Imager::File::GIF doesn't match that of Imager. Previously it
802 could be difficult to determine exactly which module was failing to

TC
824 - when downconverting samples (eg. from floating point to 8 bit)
825 Imager now rounds the sample value rather than attempting to
826 allocate input values over output values equally. The old
827 behaviour had the probably surprising effect of converting a
828 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
829 2.
830 This may result in slightly different 8 or 16-bit output images.

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

857 handle a statically linked libpng.
858 https://rt.cpan.org/Ticket/Display.html?id=74043
859
860 - if a probe includes testcode, Imager::Probe now checks that code as
861 part of the process of checking each configuration rather than as a
862 post test of the found configuration. This allows alternate
863 configurations to be checked if a matching but non-working

940 - setsamples() is now a true complement to getsamples() - it can
941 write 8-bit or floating point samples from a scalar or array
942 reference. This adds i_psamp() and i_psampf() to the C level API.
943
944 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
945 changed to make better use of the typemap, but these aren't part of
946 the perl level API anyway. There were no changes to the C level
947 interfaces to these functions.

1102 - io_glue I/O buffering re-work:
1103
1104 - reorganize io_glue to do it's own buffering by default
1105
1106 - the unbuffered functions are available as i_io_raw_read() (or
1107 raw_read() from perl) etc but are not recommended for typical
1108 use.
1109
1110 - use the new i_io_peekn() when checking for file magic to avoid
1111 seek, allowing Imager to detect the file type and read the file
1112 from an unseekable stream (for formats that don't use random
1113 access)
1114
1115 - added several new I/O layer API functions.
1116
1117 - fix the TGA performance problem, most noticably on Win32
1118 https://rt.cpan.org/Ticket/Display.html?id=70037
1119
1120 - TIFF now uses wrapper functions of the correct types to avoid casts
1121 https://rt.cpan.org/Ticket/Display.html?id=69912
1122
1123 - the callback IO object did its own buffering, controlled by the
1124 maxbuffer parameter supplied to the read() and write() methods.
1125 This buffering has been removed, to avoid redundancy with the
1126 common io_glue buffering. This also avoids a bug in that code
1127 which could rarely pass a zero length to the read callback and
1128 then panic about the result.
1129
1130 - the callback IO object now tests the result of calling the close
1131 callback, which should return true for success.
1132
1133 - the PNM reader did its own buffering. This buffering has been
1134 removed to avoid redundancy with the common io_glue buffering.
1135
1136 - previously the read handlers for fd and callback I/O layers would
1137 call the underlying interface (POSIX read or your supplied callback)
1138 until it filled the buffer. It now only makes one call.
1139
1140 - added public constructors for I/O layer objects (see Imager::IO)
1141
1142 - all core file handlers now use the i_io_foo() wrappers to gain
1143 access to buffered I/O rather than calling the I/O layer
1144 callbacks directly.
1145
1146 - all core file handlers now check for error on close.
1147
1148 - Backward compatibility: if you hava custom file handlers, you can
1149 use i_io_write() etc since they're available as macros in older
1150 versions of Imager.
1151
1152 - eliminate the final remnants of io_glue_commit_types().
1153
1154 - bump IMAGER_API_VERSION, since the above may break assumptions.
1155
1156 - removed the long unused i_gen_reader() and i_gen_writer() utility
1157 functions.

1220Development release as a sanity check for the types re-work.
8d14daab
TC
1221
1222Massive types re-work:
1223
1224 - the type used internally for pixel co-ordinates and image sizes is
1225 now 64-bit on 64-bit platforms (at least sane ones).
1226
1227 - size_t is now used consistently for memory block sizes.
1228
1229 - since this changes the binary interface, the Imager API version has
1230 been incremented. Any module that uses the API will need to be
1231 rebuilt. In most cases that will be enough, but calls to any APIs
1232 that take a pointer to image sizes may need source changes.
1233
1234 - you should be able to create very large images on 64-bit systems,
1235 if you have enough memory. Successfully created a 32768 x 49192 x
1236 3 channel image, filled with a tiled image and scaled it. The
1237 unscaled image was also successfully saved to a JPEG.
1238
1239 - check the image size before attempting to write BMP, GIF, JPEG,
1240 PNG, SGI, TGA, TIFF images.
1241
1242 - correctly handle reading TGA images over 32767 pixels wide or tall.
1243
1244Incidental changes:
1245
1246 - the gif_left and gif_top tags are now clamped to non-negative
1247 values when writing a GIF image.
1248
1249 - removed dead callback read/write code
1250
1251The default maximum memory size when reading files is now 1G.

1872 resulting in a SIGSEGV when attempting to scale an image to a size
1873 too large to fit in memory. This is a NULL pointer access issue,

1889This release primarily contains changes to improve ease of use -
1890rather than you having to convert images to the appropriate number of
1891channels, Imager handles it internally. How to handle drawing colors
1892and the default combine mode is a thornier problem left for some other
1893release.

TC
1898 - moved the imtoc.perl code into Imager::Preprocess
1899
1900 - paste() and rubthrough() now adapt the source image data to the
1901 destination, so you can now safely paste/rubthrough from greyscale
1902 images to color images or back, or from alpha channel images to
1903 noalpha channels or back.
1904 https://rt.cpan.org/Ticket/Display.html?id=30908
1905
1906 - rubthrough() now falls back to pasting when the source doesn't have
1907 an alpha channel. This effectively treats the source as having a
1908 max alpha channel, the right thing to do.
1909 http://rt.cpan.org/Ticket/Display.html?id=29944
1910
1911 - re-worked most of the area filling code to use a common set of
1912 functions when filling.
1913 Corrected normal combine mode.
1914 Rewrote most of the combine modes to match the way the SVG draft
1915 defines them with respect to a translucent source and destination.
1916 Added tests for translucent source and destination.
1917 Added tests to check 8-bit/sample and double/sample combines work
1918 similarly.

1956
1957 - handling of the left-over bit for 16-bit/pixel TGA images has been
1958 changed to match the behaviour of the GIMP. Previously the bit
1959 being set was treated as an opaque pixel, but one user reported a
1960 problem with loading such an image. I haven't been able to find any
1961 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1962 I'll match it's behaviour. See issue 114913 in the GIMP's
1963 bugzilla.

1973 - the old dynaload code used Mach API functions to load dynamic
1974 libraries on Mac OS X. These APIs have been deprecated in OS X
1975 10.5 and were causing some build problems.

2209 - reworked library probing, we can now set more than one probe
2210 function for a library. Disabled the default (non-freetype-config)
2211 library probe and added an extra probe function that searches for
2212 both ft2build.h and whatever it includes, and adds -I as needed.
2213 Hopefully this will fix build problems like

2281Imager 0.55 - 16 Dec 2006
2282===========
2283
2284This is primarily a bug fix release.
2285
2286Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2287
2288There is one new feature:
2289
2290 - the Win32 font driver now supports UTF8 (RT 22166)
2291 http://www.cpanforum.com/threads/3276
2292 http://rt.cpan.org/Ticket/Display.html?id=22166
2293
2294Several bugs were fixed:
2295
2296 - the string() method would not output the string "0"
2297 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2298
2299 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2300 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2301
2302 - the gif_disposal and gif_user_input tags weren't being read from
2303 the file correctly
2304 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2305
2306 - gif.c was failing to build under MSVC
2307 http://rt.cpan.org/Ticket/Display.html?id=23922
2308
2309 - in some cases strings passed to the string() method were treated as
2310 terminated by NUL (chr 0)
2311 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2312
2313 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2314 that's the default build name for zlib on Win32.
2315 http://rt.cpan.org/Ticket/Display.html?id=23064
2316
2317 - search $Config{incpath} for headers too, which we should have been
2318 doing all along.
2319
2320Win32 font driver fixes:
2321
2322 - the global descent value from bounding box was the wrong sign
2323 http://www.cpanforum.com/threads/3276
2324
2325 - if the first or last glyph overflowed the left or right side of the
2326 advance width they would be clipped
2327
2328
2329Imager 0.54 - 14 Sep 2006
2330===========
2331
2332This is primarily a feature release:
2333
2334 - a new qtype value 'mixing' has been added to the scale()
2335 method. This is faster than 'normal', slower than 'preview'. This
2336 is based on the method used by pnmscale, and seems to produce less
2337 blurry results than normal.
2338 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2339
2340 - the rubthrough() method can now render onto images with an alpha
2341 channel.
2342 http://rt.cpan.org/Ticket/Display.html?id=20678
2343
2344 - the read_multi() method now falls back to calling doing a single
2345 image read via the read() method and write_multi() will now fall
2346 back to calling write() if a single image is supplied. This means
2347 you can simply call the read_multi() or write_multi() functions
2348 without having to check if the type is formatted by that method.
2349 http://rt.cpan.org/Ticket/Display.html?id=19457
2350 http://rt.cpan.org/Ticket/Display.html?id=19458
2351
2352 - the GIF loop extension can now be written. If you don't have
2353 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2354 should upgrade.
2355 http://rt.cpan.org/Ticket/Display.html?id=21185
2356
2357 - getscanline() and setscanline() can now read/write palette index
2358 based data from/to the image for paletted images, by setting type to
2359 'index'.
2360 http://rt.cpan.org/Ticket/Display.html?id=20338
2361
2362 - we no longer hassle you to disable GIF support
2363 http://rt.cpan.org/Ticket/Display.html?id=20687
2364
2365 - minor documentation fixes
2366
2367
2368Imager 0.53 - 26 Jul 2006
2369===========
2370
2371This is a bugfix release.
2372
2373Some test code was left in a code path not covered by the test
2374suite. A test was added to cover this code path and the test code was
2375removed.
2376http://rt.cpan.org/Public/Bug/Display.html?id=20705
2377
2378
2379Imager 0.52 - 25 Jul 2006
2380===========
2381
2382This is primarily a feature release, but contains a fair few bug
2383fixes, new features:
2384
2385 - ability to read and write MS Windows ICO and CUR files
2386
2387 - you can now add file format plugins to support new file formats
2388
2389 - add POD coverage tests
2390
2391 - setcolors() and addcolors() now accept color names and so on
2392 instead of requiring Imager::Color objects.
2393 http://rt.cpan.org/Ticket/Display.html?id=20056
2394
2395 - flood_fill() can now fill to a specified border color instead of
2396 just to the area the same color as the seed.
2397 http://rt.cpan.org/Ticket/Display.html?id=19618
2398
2399
2400Bug fixes:
2401
2402 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2403 calculating the advance width.
2404 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2405
2406 - bounding_box for the T1 driver wasn't including leading and
2407 trailing spaces in the bounding box as the other drivers did, it also
2408 produced strange results for empty strings or strings containing only
2409 spaces
2410
2411 - when reading CMYK jpeg images they were being transferred to the
2412 image object as is, producing a four channel image. It only looked ok
2413 due to an old still unfixed Photoshop bug. We now convert from the
2414 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2415 http://rt.cpan.org/Ticket/Display.html?id=20416
2416
2417 - reading a CYMK TIFF would result in a 4 channel image, reading any
2418 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2419 result in an error.
2420 http://rt.cpan.org/Ticket/Display.html?id=20415
2421
2422 - added /usr/local/include to the default include search path, since
2423 we were already searching /usr/local/lib for libraries.
2424
2425And various minor fixes and documentation updates.
2426
2427
2428Imager 0.51 - 23 Apr 2006

2432 a crash
2433 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2434
2435 - fix mis-processing of the src_maxx and src_maxy parameters of the
2436 paste() method
2437 http://rt.cpan.org/Public/Bug/Display.html?id=18712

2442
2443
2444Imager 0.50 - 29 Mar 2006
2445===========
2446
2447 - CRITICAL: fixes a segmentation fault from attempting to write a 2
2448 or 4 channel image to jpeg or a 2 channel image to tga where the
2449 output is an in-memeory buffer.
2450 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2451
2452 - fixes an incorrect pointer parameter in the PNG code
2453 http://rt.cpan.org/Public/Bug/Display.html?id=18051
2454
2455 - skip Inline::C tests when building in a directory with spaces
2456 http://rt.cpan.org/Public/Bug/Display.html?id=18049
