a3b721bb
TC
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
59fd0c6b 64Lower severity (according to Coverity):
c4fd43be
TC
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 111 - fix an unsigned comparison when converting character code to a
59fd0c6b
TC
112 glyph index with a NULL character map when calculating the glyph
113 for display for FT1. This should be rare. CID 185297.
114
115 - fix a similar bug when calculating whether a glyph is present for
116 has_chars() for FT1. CID 185302.
70501294 117
6fa51f9c
TC
118 - i_img_info() (C API) no longer tries to handle a NULL image object
119 pointer. CID 185298.
120
a2c2d400
TC
121 - re-work testing for size_t overflow for circle/random
122 super-sampling for fountain fills. CID 185304.
123
a3b721bb
TC
124[1] The first two build submissions ended up at the end of a ~400
125build queue, and seemed to have been cancelled by Coverity. A build
126submitted on NYE went through in minutes.

TC
128Imager 1.008 - 31 Dec 2018
129============
130
75e155e1 131 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
132 This allows file formats that store EXIF data as blobs similarly
133 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 134
b5bbf161 135 - added some more file extensions to image file type mappings
75e155e1
TC
136
137 - added add_type_extensions() class method
138

152
ac3e79fb
TC
153Imager 1.006 - 26 Aug 2017
154============
155
ba7ddbae
TC
156 - the internal i_errors() function now correctly allocates the stack
157 space needed for its result.
158 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
159
160 - t/100-base/020-color.t now uses Imager::Test's test functions
161 instead of its own.
162 https://rt.cpan.org/Ticket/Display.html?id=111993
163
344dda51
TC
164 - write_multi() now returns an error result (a false value) if called
165 with a non-(Imager image object). Previously it would typically
166 crash.
167 https://rt.cpan.org/Ticket/Display.html?id=117878
168
169 - improve the documentation of the jpegquality parameter when
170 writing JPEG files.
171
172 - add code to mitigate CVE-2016-1238, Imager will no longer search the
173 default current directory entry in @INC when searching for file
174 format support modules.

176Imager 1.005 - 16 Apr 2016
177============
178
179It's now been ten years since I switched to the new Changes file in
180release 0.55.
181
cd0109d8
TC
182 - revert the ivdformat probes, they don't work as is and trying to
183 fix them is too much work for now.
184
6f1cbfed
TC
185Imager 1.004_004 - 15 Apr 2016
186================
187
9c45cc49
TC
188 - test that the ivdformat from Config is correct and look for a valid
189 one if it isn't.
190 For the strange Win32 failures.
191
192 - fix a copy and paste error in pod in samples/samp-form.cgi
193
5cea6ea1
TC
194Imager 1.004_003 - 23 Mar 2016
195================
196
bd2d657d
TC
197 - add some extra error reporting to the I/O layers tests, this might
198 help catch a failure seen on Win32.

TC
201Imager 1.004_002 - 20 Mar 2016
202================
203
735b3e7b
TC
204 - don't use the seek() method on opened() handles in
205 t/200-file/400-basic.t. In older versions of perl such handles are
206 only IO::Handle objects, not IO::File, and don't have a seek()
207 method.

TC
209Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
210================
211
08914ed1
TC
212 - re-work the t/200-file/400-basic.t to correctly handle failures
213 It's custom ok() function didn't have a prototype and didn't use scalar().
214 This caused ok() to use the note instead of the value being tested when
215 the method called returned an empty list. For an example of the problem
e6226ce5 216 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 217
a2791e47
TC
218 - remove some noise from when Imager tried to work with bugs in old
219 versions of giflib. I can't do much about the new bugs.
08914ed1 220
e6226ce5
TC
221 - the new autolevels filter (Imager 0.99) used an integer for the
222 sample scaling factor which caused the top output level to be too
223 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
224 https://rt.cpan.org/Ticket/Display.html?id=111871
225
e6226ce5 226 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
227 minimum and maximum luminance from the histogram. This slightly
228 reduced the contrast of the output image.
229 https://rt.cpan.org/Ticket/Display.html?id=111871
230
231 - the new autolevels filter now uses a lookup table for 8-bit images
232 to avoid a floating point multiply for each sample.
233 https://rt.cpan.org/Ticket/Display.html?id=111871
234
e6226ce5
TC
235 - fixed several memory leaks detected by valgrind:
236
237 - addcolors() leaked the temporary array of colors supplied to the
238 internal API
239
240 - make_palette() leaked the temporary image array (not the images
241 themselves) passed to the internal API.
242
243 - combine()/i_combine() leaked its working row buffers
244
245 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
246 buffer if there were too many colors
247
248 - getcolorcount()/i_count_colors() leaked the sample buffer if
249 there were too many colors.
250
251 - the nearest_color filter (undocumented until I find a use for it)
252 leaked both temporaries passed to the API and internal buffers
253
a2791e47
TC
254 - the internal process of upgrading a paletted image to a direct
255 color image would leak a context object reference count.
256
257 - a write failure when writing to a GIF file could leak memory.
258
259 - failing to write to a 1-bit/pixel ICO image could leak memory.
260
261 - Imager no longer deliberately leaks the context object from the
262 initial thread. This was done to ensure there was always a context
263 object available, but the code that needed that now handles the
264 lack correctly,
265
e6226ce5
TC
266 - fixed some uninitialized memory usage detected by valgrind:
267
268 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
269 i_matrix_transform_bg() didn't initialize a working color value
270 if there was zero pixel coverage.
271
272 - i_ft2_cp() didn't initialize the complete color when producing an
273 intermediate image. This caused uninitialized value usage when
274 logging the color.

TC
276Imager 1.004 - 8 Nov 2015
277============
278
5ebfb369
TC
279 - Imager::Color::Table is now pre-loaded by the preload() method.
280 https://rt.cpan.org/Ticket/Display.html?id=104896
281
282 - fix an assertion triggered under perl 5.23.4.
283 Thanks to A. Sinan Unur for the report and the patch.
284
7b638aba
TC
285 - Imager->new can now be used to read raw image files.
286 https://rt.cpan.org/Ticket/Display.html?id=106836
f7160b21 287 Thanks to Richard Kelsch for reporting this.
7b638aba
TC
288
289 - deal with output changes from Pod::Spell

TC
292Imager 1.003 - 12 May 2015
293============
294
0fda3cfd
TC
295 - update 1.002 release notes to include the center change for filled
296 circle drawing.
297
298 - flood_fill() would escape beyond a 4-connected space under some
299 circumstances.
300 Added many more flood_fill() tests.

TC
303Imager 1.002 - 3 Apr 2015
304============
305
334b8922
TC
306 - drawing anti-aliased filled circles is now 10 to 50 times faster
307 depending on the size of the circle.
0fda3cfd
TC
308 This also changed the center from being the center of the pixel to
309 being the top left of the pixel to match the filled arcs drawn by
310 arc().
334b8922
TC
311 https://rt.cpan.org/Ticket/Display.html?id=101682
312
313 - enhancements to polygon filling:
314
315 - added a mode parameter to control how overlapping regions behave
316
317 - added a polypolygon() method to fill more than one polygon at a
318 time
319
320 - polygon filling is now exposed through the API.
321
45c8e262
TC
322 - added colormodel(), alphachannel() and colorchannels() methods.
323 These were added for two reasons:
324
325 - a future version of Imager may allow the number of channels in
326 an image to not directly represent the color model of an image.
327 eg. a greyscale TIFF image with multiple alpha channels.
328
329 - a future version of Imager may allow an image to be read without
330 translation, for example a TIFF file that contains measurements
0fda3cfd 331 from an instrument. Currently Imager transforms the samples into
d96c4de8 332 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
333 the value back.
334
335 An untranslated image would be unusable as image data, so
336 colormodel() would return "unknown" in this case.
337
338 Similarly a CMYK image might be returned as an "unknown" color
339 model image, if the caller chooses to disable translation to
340 RGB.

380Imager 0.99_02 - 21 Jul 2014
381==============
382
5dab5b9a
TC
383 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
384 the blue channel in the generated palette, and allow each color
385 component to be in the range 100..255 instead of just 100..254.
386 Thanks to Ralf Neubauer.
387 https://rt.cpan.org/Ticket/Display.html?id=97086
388
389 - revert "improved the XS for i_io_read() and i_io_raw_read()"
390 This caused problems with older perls and didn't provide much of a
391 performance improvement.
392

418===========
419
dce1523b
TC
420 - Imager::IO->new_buffer() (and hence Imager->read()'s data
421 parameter) now accepts a reference to a scalar as well as just a
422 plain scalar.

dce1523b
TC
424
425 - Imager::IO->new_buffer() now always makes a copy of the passed in
426 buffer to avoid problems with temporary objects used for the return
427 value of SvPVbyte().

446 - Imager::File::PNG now supports libpng 1.6.10.
447 1.6.10 changed CRC errors from benign errors to normal errors,
448 which broke the test which used CRC errors to check for benign
449 error support. Switched to using a 1-bit grey-scale image with a
450 palette to test for benign errors.

456Incompatible changes:
457
458 - the return value of setpixel() has changed.
459
460 Previously the return values for undrawable pixels vs caller errors
461 changed depending on whether you used the multiple pixel calling
462 mechanism, or the single pixel mechanism.
463
464 Now:
465
466 - for an invalid parameter, such as an unknown colour, or missing
467 parameter, an empty list (or undef in scalar context) is
468 returned, and errstr() is set,
469
470 - otherwise the number of pixels drawn is returned. If none of
471 the pixels could be drawn (they were all outside the image), "0
472 but true" is returned.

TC
478 - when drawing on an image with an alpha channel where the source
479 minimum is greater than zero, Imager would read from beyond the end
480 of a malloc() allocated buffer. In rare circumstances this could
481 lead to some of the source image not being written to the target
482 image, or possibly to a segmentation fault.
483 I don't believe this has any security concerns beyond that.
484
0d052fd9
TC
485 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
486 text drawn would be nonsense. This would also read beyond the end
487 of a malloced buffer.

538 Mixed SampleFormat are handled incorrectly, since libtiff returns

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

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

TC
830 - when downconverting samples (eg. from floating point to 8 bit)
831 Imager now rounds the sample value rather than attempting to
832 allocate input values over output values equally. The old
833 behaviour had the probably surprising effect of converting a
834 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
835 2.
836 This may result in slightly different 8 or 16-bit output images.

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

863 handle a statically linked libpng.
864 https://rt.cpan.org/Ticket/Display.html?id=74043
865
866 - if a probe includes testcode, Imager::Probe now checks that code as
867 part of the process of checking each configuration rather than as a
868 post test of the found configuration. This allows alternate
869 configurations to be checked if a matching but non-working

946 - setsamples() is now a true complement to getsamples() - it can
947 write 8-bit or floating point samples from a scalar or array
948 reference. This adds i_psamp() and i_psampf() to the C level API.
949
950 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
951 changed to make better use of the typemap, but these aren't part of
952 the perl level API anyway. There were no changes to the C level
953 interfaces to these functions.

1108 - io_glue I/O buffering re-work:
1109
1110 - reorganize io_glue to do it's own buffering by default
1111
1112 - the unbuffered functions are available as i_io_raw_read() (or
1113 raw_read() from perl) etc but are not recommended for typical
1114 use.
1115
1116 - use the new i_io_peekn() when checking for file magic to avoid
1117 seek, allowing Imager to detect the file type and read the file
1118 from an unseekable stream (for formats that don't use random
1119 access)
1120
1121 - added several new I/O layer API functions.
1122
1123 - fix the TGA performance problem, most noticably on Win32
1124 https://rt.cpan.org/Ticket/Display.html?id=70037
1125
1126 - TIFF now uses wrapper functions of the correct types to avoid casts
1127 https://rt.cpan.org/Ticket/Display.html?id=69912
1128
1129 - the callback IO object did its own buffering, controlled by the
1130 maxbuffer parameter supplied to the read() and write() methods.
1131 This buffering has been removed, to avoid redundancy with the
1132 common io_glue buffering. This also avoids a bug in that code
1133 which could rarely pass a zero length to the read callback and
1134 then panic about the result.
1135
1136 - the callback IO object now tests the result of calling the close
1137 callback, which should return true for success.
1138
1139 - the PNM reader did its own buffering. This buffering has been
1140 removed to avoid redundancy with the common io_glue buffering.
1141
1142 - previously the read handlers for fd and callback I/O layers would
1143 call the underlying interface (POSIX read or your supplied callback)
1144 until it filled the buffer. It now only makes one call.
1145
1146 - added public constructors for I/O layer objects (see Imager::IO)
1147
1148 - all core file handlers now use the i_io_foo() wrappers to gain
1149 access to buffered I/O rather than calling the I/O layer
1150 callbacks directly.
1151
1152 - all core file handlers now check for error on close.
1153
1154 - Backward compatibility: if you hava custom file handlers, you can
1155 use i_io_write() etc since they're available as macros in older
1156 versions of Imager.
1157
1158 - eliminate the final remnants of io_glue_commit_types().
1159
1160 - bump IMAGER_API_VERSION, since the above may break assumptions.
1161
1162 - removed the long unused i_gen_reader() and i_gen_writer() utility
1163 functions.

1226Development release as a sanity check for the types re-work.
8d14daab
TC
1227
1228Massive types re-work:
1229
1230 - the type used internally for pixel co-ordinates and image sizes is
1231 now 64-bit on 64-bit platforms (at least sane ones).
1232
1233 - size_t is now used consistently for memory block sizes.
1234
1235 - since this changes the binary interface, the Imager API version has
1236 been incremented. Any module that uses the API will need to be
1237 rebuilt. In most cases that will be enough, but calls to any APIs
1238 that take a pointer to image sizes may need source changes.
1239
1240 - you should be able to create very large images on 64-bit systems,
1241 if you have enough memory. Successfully created a 32768 x 49192 x
1242 3 channel image, filled with a tiled image and scaled it. The
1243 unscaled image was also successfully saved to a JPEG.
1244
1245 - check the image size before attempting to write BMP, GIF, JPEG,
1246 PNG, SGI, TGA, TIFF images.
1247
1248 - correctly handle reading TGA images over 32767 pixels wide or tall.
1249
1250Incidental changes:
1251
1252 - the gif_left and gif_top tags are now clamped to non-negative
1253 values when writing a GIF image.
1254
1255 - removed dead callback read/write code
1256
1257The default maximum memory size when reading files is now 1G.

1895This release primarily contains changes to improve ease of use -
1896rather than you having to convert images to the appropriate number of

1904 - moved the imtoc.perl code into Imager::Preprocess
1905
1906 - paste() and rubthrough() now adapt the source image data to the
1907 destination, so you can now safely paste/rubthrough from greyscale
1908 images to color images or back, or from alpha channel images to
1909 noalpha channels or back.
1910 https://rt.cpan.org/Ticket/Display.html?id=30908
1911
1912 - rubthrough() now falls back to pasting when the source doesn't have
1913 an alpha channel. This effectively treats the source as having a
1914 max alpha channel, the right thing to do.
1915 http://rt.cpan.org/Ticket/Display.html?id=29944
1916
1917 - re-worked most of the area filling code to use a common set of
1918 functions when filling.
1919 Corrected normal combine mode.
1920 Rewrote most of the combine modes to match the way the SVG draft
1921 defines them with respect to a translucent source and destination.
1922 Added tests for translucent source and destination.
1923 Added tests to check 8-bit/sample and double/sample combines work
1924 similarly.

1963 - handling of the left-over bit for 16-bit/pixel TGA images has been
1964 changed to match the behaviour of the GIMP. Previously the bit
1965 being set was treated as an opaque pixel, but one user reported a
1966 problem with loading such an image. I haven't been able to find any
1967 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1968 I'll match it's behaviour. See issue 114913 in the GIMP's
1969 bugzilla.

1979 - the old dynaload code used Mach API functions to load dynamic
1980 libraries on Mac OS X. These APIs have been deprecated in OS X

2287Imager 0.55 - 16 Dec 2006
2288===========
2289
2290This is primarily a bug fix release.
2291
2292Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2293
2294There is one new feature:
2295
2296 - the Win32 font driver now supports UTF8 (RT 22166)
2297 http://www.cpanforum.com/threads/3276
2298 http://rt.cpan.org/Ticket/Display.html?id=22166
2299
2300Several bugs were fixed:
2301
2302 - the string() method would not output the string "0"
2303 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2304
2305 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2306 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2307
2308 - the gif_disposal and gif_user_input tags weren't being read from
2309 the file correctly
2310 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2311
2312 - gif.c was failing to build under MSVC
2313 http://rt.cpan.org/Ticket/Display.html?id=23922
2314
2315 - in some cases strings passed to the string() method were treated as
2316 terminated by NUL (chr 0)
2317 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2318
2319 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2320 that's the default build name for zlib on Win32.
2321 http://rt.cpan.org/Ticket/Display.html?id=23064
2322
2323 - search $Config{incpath} for headers too, which we should have been
2324 doing all along.
2325
2326Win32 font driver fixes:
2327
2328 - the global descent value from bounding box was the wrong sign
2329 http://www.cpanforum.com/threads/3276
2330
2331 - if the first or last glyph overflowed the left or right side of the
2332 advance width they would be clipped
2333
2334
2335Imager 0.54 - 14 Sep 2006
2336===========
2337
2338This is primarily a feature release:
2339
2340 - a new qtype value 'mixing' has been added to the scale()
2341 method. This is faster than 'normal', slower than 'preview'. This
2342 is based on the method used by pnmscale, and seems to produce less
2343 blurry results than normal.
2344 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2345
2346 - the rubthrough() method can now render onto images with an alpha
2347 channel.
2348 http://rt.cpan.org/Ticket/Display.html?id=20678
2349
2350 - the read_multi() method now falls back to calling doing a single
2351 image read via the read() method and write_multi() will now fall
2352 back to calling write() if a single image is supplied. This means
2353 you can simply call the read_multi() or write_multi() functions
2354 without having to check if the type is formatted by that method.
2355 http://rt.cpan.org/Ticket/Display.html?id=19457
2356 http://rt.cpan.org/Ticket/Display.html?id=19458
2357
2358 - the GIF loop extension can now be written. If you don't have
2359 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2360 should upgrade.
2361 http://rt.cpan.org/Ticket/Display.html?id=21185
2362
2363 - getscanline() and setscanline() can now read/write palette index
2364 based data from/to the image for paletted images, by setting type to
2365 'index'.
2366 http://rt.cpan.org/Ticket/Display.html?id=20338
2367
2368 - we no longer hassle you to disable GIF support
2369 http://rt.cpan.org/Ticket/Display.html?id=20687
2370
2371 - minor documentation fixes
2372
2373
2374Imager 0.53 - 26 Jul 2006
2375===========
2376
2377This is a bugfix release.
2378
2379Some test code was left in a code path not covered by the test
2380suite. A test was added to cover this code path and the test code was
2381removed.

2384
2385Imager 0.52 - 25 Jul 2006
2386===========
2387
2388This is primarily a feature release, but contains a fair few bug
2389fixes, new features:
2390
2391 - ability to read and write MS Windows ICO and CUR files
2392
2393 - you can now add file format plugins to support new file formats
2394
2395 - add POD coverage tests
2396
2397 - setcolors() and addcolors() now accept color names and so on
2398 instead of requiring Imager::Color objects.
2399 http://rt.cpan.org/Ticket/Display.html?id=20056
2400
2401 - flood_fill() can now fill to a specified border color instead of
2402 just to the area the same color as the seed.
2403 http://rt.cpan.org/Ticket/Display.html?id=19618
2404
2405
2406Bug fixes:
2407
2408 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2409 calculating the advance width.
2410 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2411
2412 - bounding_box for the T1 driver wasn't including leading and
2413 trailing spaces in the bounding box as the other drivers did, it also
2414 produced strange results for empty strings or strings containing only
2415 spaces
2416
2417 - when reading CMYK jpeg images they were being transferred to the
2418 image object as is, producing a four channel image. It only looked ok
2419 due to an old still unfixed Photoshop bug. We now convert from the
2420 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2421 http://rt.cpan.org/Ticket/Display.html?id=20416
2422
2423 - reading a CYMK TIFF would result in a 4 channel image, reading any
2424 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2425 result in an error.
2426 http://rt.cpan.org/Ticket/Display.html?id=20415
2427
2428 - added /usr/local/include to the default include search path, since
2429 we were already searching /usr/local/lib for libraries.
2430
2431And various minor fixes and documentation updates.
2432
2433
2434Imager 0.51 - 23 Apr 2006

2440
2441 - fix mis-processing of the src_maxx and src_maxy parameters of the

2455 output is an in-memeory buffer.
