TC
4============

1456b645
TC
6Critical issue:
7
8 - drawing a filled, anti-aliased circle to the left or right of the
9 image (not within the image at all) would cause a buffer overflow.
10 https://rt.cpan.org/Ticket/Display.html?id=128208
11
a3b721bb
TC
12General changes:
13
14 - to_paletted() and make_palette() now fail (with an error in
15 errstr()) if invalid quantization parameters are supplied.
16
35ec3a87
TC
17 - map() would corrupt a channel if there was a gap in the arrayref of
18 channels. Detected by Coverity. CID 185300.
19
5824f4c2
TC
20 - most numeric parameters to the XS implementation now throw an
21 exception if supplied an unoverloaded reference.
22 https://rt.cpan.org/Ticket/Display.html?id=128208
23
e32d3a7c
TC
24Coverity finally finished a build[1], fixed several of the problems
25found. Coverity went down before I could finish working through them.
1791cbdb 26
8445279e
TC
27High severity:
28
1791cbdb 29 - reading a color-mapped TGA file with an id string would cause a
8445279e 30 double-free if the palette was truncated. CID 185317.
1791cbdb 31
6494c395
TC
32 - mixing scaling to sizes where the accumulator row, the working
33 output row or the working input row didn't fit into the address
34 space could result in memory leaks. This can probably only be
8445279e 35 reproduced on very wide floating-point sample images. CID 185318.
6494c395 36
fc24ca5f 37 - convert an array style function parameter pointer to pointer style
3d7b055c 38 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 39 CID 185343.
3d7b055c 40
8445279e 41 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 42
20c297d4 43 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 44 implementation. CID 185303.
20c297d4 45
fc24ca5f 46 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 47 drawing (it should always end up being set.) CID 185341.
fc24ca5f 48
f7675b46 49 - addi style makemap could potentially read one past the end of an
8445279e 50 array. CID 185337.
f7675b46 51
58ec1fde
TC
52 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
53 would result in read beyond the end of the built-in hatch array.
54 Negative values (which Coverity didn't complain about) could also
8445279e 55 cause problems. CID 185331.
58ec1fde 56
b7346865
TC
57 - the Imager::Color set_internal() interal method no longer
58 calls the over-complicated ICL_set_internal() (which is retained
59 only for the old API.) Coverity complained that this leaked, but
60 this could only occur with an invalid (NULL pointer) color object.
8445279e 61 CID 185323.
b7346865 62
785364c1
TC
63 - the underlying implementation of the map() method could read before
64 the beginning on an allocated array if supplied with inconsistent
65 parameters, which Coverity complained about. No Imager code calls
66 that function with inconsistent parameters, but a
8445279e 67 belt-and-suspenders check was added. CID 185315.
785364c1 68
eb7e48c9
TC
69 - Coverity complained a call to i_getcolors(), used by the
70 implementation of the is_bilevel() method could leave the fetched
8445279e 71 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 72
c1c8b1e9
TC
73 - a numeric combining mode of 13 (eg. as a parameter to
74 Imager::Fill->new())could cause an invalid array read in
75 i_get_combine() due to a fencepost error in validating the combine
8445279e 76 number. CID 185299.
c1c8b1e9 77
59fd0c6b 78Lower severity (according to Coverity):
c4fd43be
TC
79
80 - avoid an unneeded EXTEND() call when the FT1 has_chars()
81 implementation returns 0. CID 185350.
82
83 - avoid accessing a possibly NULL map from MakeMapObject() in a
84 logging call. (GIF) CID 185296.
85
4615ad8d
TC
86 - gradgen() allocated the wrong amount of space (always too much) for
87 the color array. CID 185291.
88
ea3099db
TC
89 - avoid dead code in i_tt_glyph_names(). CID 185321.
90
8b810590
TC
91 - avoid dead code in i_get_anonymous_color_histo(), which is the
92 implementation of getcolorusage(). CID 185327.
93
4eb9a521
TC
94 - avoid dead code in i_ft2_glyph_name(), which is the implementation
95 of glyph_names() for FT2. CID 185342.
96
c028aa12
TC
97 - avoid dead code in i_t1_glyph_names(), which is the implementation
98 of glyph_names() for T1. CID 185322.
99
e7772cea
TC
100 - avoid an unneeded EXTEND() call when the FT2 has_chars()
101 implementation returns 0. CID 185292.
102
596f3eee
TC
103 - the unpack code for ICO/CUR file handling could extend 32-bit
104 unsigned values to 64-bit signed. I believe this is harmless. CID
105 185319.
106
a2ca2b80
TC
107 - remove an unneeded check when terminating the stream for JPEG
108 writing. CID 185347.
109
56ce7446
TC
110 - skip an unneeded check when freeing the combine temp buffer in the
111 fountain filter. CID 185286.
112
113 - check the combine function pointer consistently rather than the
114 combine code in one place in the fountain filter.
115
a3b721bb
TC
116 - error diffusion now validates a custom error diffusion map and reports
117 an error if it's bad. CID 185288.
118
215d9ead
TC
119 - avoid discarding the value of i_io_getc() when scanning numbers in
120 pnm.c. CID 185293.
121
9ca939d0
TC
122 - handle failure to clone the log filehandle when cloning the Imager
123 context object on thread creation. CID 185294.
124
70501294 125 - fix an unsigned comparison when converting character code to a
59fd0c6b
TC
126 glyph index with a NULL character map when calculating the glyph
127 for display for FT1. This should be rare. CID 185297.
128
129 - fix a similar bug when calculating whether a glyph is present for
130 has_chars() for FT1. CID 185302.
70501294 131
6fa51f9c
TC
132 - i_img_info() (C API) no longer tries to handle a NULL image object
133 pointer. CID 185298.
134
a2c2d400
TC
135 - re-work testing for size_t overflow for circle/random
136 super-sampling for fountain fills. CID 185304.
137
8e2e2347
TC
138 - don't check if the unsigned size passed to Imager's malloc wrapper
139 (mymalloc) is negative. Left from when that parameter was signed.
140 CID 185305.
141
0c16f204
TC
142 - make some types larger and add a cast to prevent integer overflows
143 when calculating a palette with median cut for extraordinarily
144 large images. CID 185306.
145
748bfdfc
TC
146 - don't check if the unsigned size supplied to
147 im_set_image_file_limits() is negative. CID 185307.
148
57cc9afe 149[1] The first two build submissions ended up at the end of a ~400 item
a3b721bb
TC
150build queue, and seemed to have been cancelled by Coverity. A build
151submitted on NYE went through in minutes.
152
b5bbf161
TC
153Imager 1.008 - 31 Dec 2018
154============
155
75e155e1 156 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
157 This allows file formats that store EXIF data as blobs similarly
158 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 159
b5bbf161 160 - added some more file extensions to image file type mappings
75e155e1
TC
161
162 - added add_type_extensions() class method
163
f38e738a
TC
164 - Imager::Files now links to Imager::Install when discussing
165 appropriate libraries.
166 https://rt.cpan.org/Ticket/Display.html?id=127575
167
b5bbf161 168Imager 1.007 - 24 Nov 2018
75e155e1
TC
169============
170
a9fa5463
TC
171 - add png_compression_level tag for writing PNG files.
172
173 - avoid flooring a second time in matrix transform interpolation.
174 https://rt.cpan.org/Ticket/Display.html?id=124001
175
434c2338
TC
176 - produce v2 metadata.
177 Includes change from the ticket and updates to sub-modules.
178 https://rt.cpan.org/Ticket/Display.html?id=127216
179
d1d8320e
TC
180 - improve error reporting for the polygon() method
181
ac3e79fb
TC
182Imager 1.006 - 26 Aug 2017
183============
184
ba7ddbae
TC
185 - the internal i_errors() function now correctly allocates the stack
186 space needed for its result.
187 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
188
189 - t/100-base/020-color.t now uses Imager::Test's test functions
190 instead of its own.
191 https://rt.cpan.org/Ticket/Display.html?id=111993
192
344dda51
TC
193 - write_multi() now returns an error result (a false value) if called
194 with a non-(Imager image object). Previously it would typically
195 crash.
196 https://rt.cpan.org/Ticket/Display.html?id=117878
197
198 - improve the documentation of the jpegquality parameter when
199 writing JPEG files.
200
201 - add code to mitigate CVE-2016-1238, Imager will no longer search the
202 default current directory entry in @INC when searching for file
203 format support modules.
204
c5e09af4
TC
205Imager 1.005 - 16 Apr 2016
206============
207
208It's now been ten years since I switched to the new Changes file in
209release 0.55.
210
cd0109d8
TC
211 - revert the ivdformat probes, they don't work as is and trying to
212 fix them is too much work for now.
213
6f1cbfed
TC
214Imager 1.004_004 - 15 Apr 2016
215================
216
9c45cc49
TC
217 - test that the ivdformat from Config is correct and look for a valid
218 one if it isn't.
219 For the strange Win32 failures.
220
221 - fix a copy and paste error in pod in samples/samp-form.cgi
222
5cea6ea1
TC
223Imager 1.004_003 - 23 Mar 2016
224================
225
bd2d657d
TC
226 - add some extra error reporting to the I/O layers tests, this might
227 help catch a failure seen on Win32.
228 http://cpantesters.org/cpan/report/99781689-6bf5-1014-897a-75cb4eee1325
229
2f4c4539
TC
230Imager 1.004_002 - 20 Mar 2016
231================
232
735b3e7b
TC
233 - don't use the seek() method on opened() handles in
234 t/200-file/400-basic.t. In older versions of perl such handles are
235 only IO::Handle objects, not IO::File, and don't have a seek()
236 method.
237
d47f1478
TC
238Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
239================
240
08914ed1
TC
241 - re-work the t/200-file/400-basic.t to correctly handle failures
242 It's custom ok() function didn't have a prototype and didn't use scalar().
243 This caused ok() to use the note instead of the value being tested when
244 the method called returned an empty list. For an example of the problem
e6226ce5 245 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 246
a2791e47
TC
247 - remove some noise from when Imager tried to work with bugs in old
248 versions of giflib. I can't do much about the new bugs.
08914ed1 249
e6226ce5
TC
250 - the new autolevels filter (Imager 0.99) used an integer for the
251 sample scaling factor which caused the top output level to be too
252 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
253 https://rt.cpan.org/Ticket/Display.html?id=111871
254
e6226ce5 255 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
256 minimum and maximum luminance from the histogram. This slightly
257 reduced the contrast of the output image.
258 https://rt.cpan.org/Ticket/Display.html?id=111871
259
260 - the new autolevels filter now uses a lookup table for 8-bit images
261 to avoid a floating point multiply for each sample.
262 https://rt.cpan.org/Ticket/Display.html?id=111871
263
e6226ce5
TC
264 - fixed several memory leaks detected by valgrind:
265
266 - addcolors() leaked the temporary array of colors supplied to the
267 internal API
268
269 - make_palette() leaked the temporary image array (not the images
270 themselves) passed to the internal API.
271
272 - combine()/i_combine() leaked its working row buffers
273
274 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
275 buffer if there were too many colors
276
277 - getcolorcount()/i_count_colors() leaked the sample buffer if
278 there were too many colors.
279
280 - the nearest_color filter (undocumented until I find a use for it)
281 leaked both temporaries passed to the API and internal buffers
282
a2791e47
TC
283 - the internal process of upgrading a paletted image to a direct
284 color image would leak a context object reference count.
285
286 - a write failure when writing to a GIF file could leak memory.
287
288 - failing to write to a 1-bit/pixel ICO image could leak memory.
289
290 - Imager no longer deliberately leaks the context object from the
291 initial thread. This was done to ensure there was always a context
292 object available, but the code that needed that now handles the
293 lack correctly,
294
e6226ce5
TC
295 - fixed some uninitialized memory usage detected by valgrind:
296
297 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
298 i_matrix_transform_bg() didn't initialize a working color value
299 if there was zero pixel coverage.
300
301 - i_ft2_cp() didn't initialize the complete color when producing an
302 intermediate image. This caused uninitialized value usage when
303 logging the color.
08914ed1 304
396eb238
TC
305Imager 1.004 - 8 Nov 2015
306============
307
5ebfb369
TC
308 - Imager::Color::Table is now pre-loaded by the preload() method.
309 https://rt.cpan.org/Ticket/Display.html?id=104896
310
311 - fix an assertion triggered under perl 5.23.4.
312 Thanks to A. Sinan Unur for the report and the patch.
313
7b638aba
TC
314 - Imager->new can now be used to read raw image files.
315 https://rt.cpan.org/Ticket/Display.html?id=106836
f7160b21 316 Thanks to Richard Kelsch for reporting this.
7b638aba
TC
317
318 - deal with output changes from Pod::Spell
319 https://github.com/perl-pod/Pod-Spell/issues/21
320
0d1baac8
TC
321Imager 1.003 - 12 May 2015
322============
323
0fda3cfd
TC
324 - update 1.002 release notes to include the center change for filled
325 circle drawing.
326
327 - flood_fill() would escape beyond a 4-connected space under some
328 circumstances.
329 Added many more flood_fill() tests.
330 https://rt.cpan.org/Ticket/Display.html?id=103786
331
647a47c9
TC
332Imager 1.002 - 3 Apr 2015
333============
334
334b8922
TC
335 - drawing anti-aliased filled circles is now 10 to 50 times faster
336 depending on the size of the circle.
0fda3cfd
TC
337 This also changed the center from being the center of the pixel to
338 being the top left of the pixel to match the filled arcs drawn by
339 arc().
334b8922
TC
340 https://rt.cpan.org/Ticket/Display.html?id=101682
341
342 - enhancements to polygon filling:
343
344 - added a mode parameter to control how overlapping regions behave
345
346 - added a polypolygon() method to fill more than one polygon at a
347 time
348
349 - polygon filling is now exposed through the API.
350
45c8e262
TC
351 - added colormodel(), alphachannel() and colorchannels() methods.
352 These were added for two reasons:
353
354 - a future version of Imager may allow the number of channels in
355 an image to not directly represent the color model of an image.
356 eg. a greyscale TIFF image with multiple alpha channels.
357
358 - a future version of Imager may allow an image to be read without
359 translation, for example a TIFF file that contains measurements
0fda3cfd 360 from an instrument. Currently Imager transforms the samples into
d96c4de8 361 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
362 the value back.
363
364 An untranslated image would be unusable as image data, so
365 colormodel() would return "unknown" in this case.
366
367 Similarly a CMYK image might be returned as an "unknown" color
368 model image, if the caller chooses to disable translation to
369 RGB.

372============
373
aca60e01
TC
374 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict

399Imager 1.000 - 28 Jul 2014
400============
401
402There's nothing special about Imager 1.000, it's just another release.
403
fa3dac1d
TC
404 - fix the skip check for the iolayer qr// buffer test
405
406 - improve error reporting for the iolayer test failing on a small
407 number of Win32 CPAN testers

TC
409Imager 0.99_02 - 21 Jul 2014
410==============
411
5dab5b9a
TC
412 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
413 the blue channel in the generated palette, and allow each color
414 component to be in the range 100..255 instead of just 100..254.
415 Thanks to Ralf Neubauer.
416 https://rt.cpan.org/Ticket/Display.html?id=97086
417
418 - revert "improved the XS for i_io_read() and i_io_raw_read()"
419 This caused problems with older perls and didn't provide much of a
420 performance improvement.
421
5bf25bc2 422 - support Inline 0.57 and later.
6d47a6af 423 Inline 0.57 changed the "with" interface.

425
6d47a6af
TC
426 - don't define our own MAXINT macro, it conflicts with windows header

432
7b486870
TC

475 - Imager::File::PNG now supports libpng 1.6.10.
476 1.6.10 changed CRC errors from benign errors to normal errors,
477 which broke the test which used CRC errors to check for benign
478 error support. Switched to using a 1-bit grey-scale image with a
479 palette to test for benign errors.

483===========

TC
485Incompatible changes:
486
487 - the return value of setpixel() has changed.
488
489 Previously the return values for undrawable pixels vs caller errors
490 changed depending on whether you used the multiple pixel calling
491 mechanism, or the single pixel mechanism.
492
493 Now:
494
495 - for an invalid parameter, such as an unknown colour, or missing
496 parameter, an empty list (or undef in scalar context) is
497 returned, and errstr() is set,
498
499 - otherwise the number of pixels drawn is returned. If none of
500 the pixels could be drawn (they were all outside the image), "0
501 but true" is returned.

504
505Other changes:
506
6ba09ab9
TC
507 - when drawing on an image with an alpha channel where the source
508 minimum is greater than zero, Imager would read from beyond the end
509 of a malloc() allocated buffer. In rare circumstances this could
510 lead to some of the source image not being written to the target
511 image, or possibly to a segmentation fault.
512 I don't believe this has any security concerns beyond that.
513
0d052fd9
TC
514 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
515 text drawn would be nonsense. This would also read beyond the end
516 of a malloced buffer.
517
13671b17

518 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be

567 Mixed SampleFormat are handled incorrectly, since libtiff returns

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

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

TC
859 - when downconverting samples (eg. from floating point to 8 bit)
860 Imager now rounds the sample value rather than attempting to
861 allocate input values over output values equally. The old
862 behaviour had the probably surprising effect of converting a
863 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
864 2.
865 This may result in slightly different 8 or 16-bit output images.

878 - pkg-config could sometimes return a library that was in a directory
879 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
880 If no -L is included in the pkg-config library information check if
881 EU::MM can find the library, and if not, search our configured
882 directories and insert that into the library flags.

885 - Imager::Probe can now probe for libraries with dependent libraries,
886 common for static linking, eg. libpng requires libz.
887 https://rt.cpan.org/Ticket/Display.html?id=74043
888
889 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.

891 - added alternative probe configurations that try to link libz, to
892 handle a statically linked libpng.
893 https://rt.cpan.org/Ticket/Display.html?id=74043
894
895 - if a probe includes testcode, Imager::Probe now checks that code as
896 part of the process of checking each configuration rather than as a
897 post test of the found configuration. This allows alternate
898 configurations to be checked if a matching but non-working
899 configuration is found.

1137 - io_glue I/O buffering re-work:
1138
1139 - reorganize io_glue to do it's own buffering by default
1140
1141 - the unbuffered functions are available as i_io_raw_read() (or
1142 raw_read() from perl) etc but are not recommended for typical
1143 use.
1144
1145 - use the new i_io_peekn() when checking for file magic to avoid
1146 seek, allowing Imager to detect the file type and read the file
1147 from an unseekable stream (for formats that don't use random
1148 access)
1149
1150 - added several new I/O layer API functions.

1156 https://rt.cpan.org/Ticket/Display.html?id=69912
1157
1158 - the callback IO object did its own buffering, controlled by the
1159 maxbuffer parameter supplied to the read() and write() methods.
1160 This buffering has been removed, to avoid redundancy with the
1161 common io_glue buffering. This also avoids a bug in that code
1162 which could rarely pass a zero length to the read callback and
1163 then panic about the result.
1164
1165 - the callback IO object now tests the result of calling the close
1166 callback, which should return true for success.
1167
1168 - the PNM reader did its own buffering. This buffering has been
1169 removed to avoid redundancy with the common io_glue buffering.
1170
1171 - previously the read handlers for fd and callback I/O layers would
1172 call the underlying interface (POSIX read or your supplied callback)
1173 until it filled the buffer. It now only makes one call.
1174
1175 - added public constructors for I/O layer objects (see Imager::IO)
1176
1177 - all core file handlers now use the i_io_foo() wrappers to gain
1178 access to buffered I/O rather than calling the I/O layer
1179 callbacks directly.
1180
1181 - all core file handlers now check for error on close.
1182
1183 - Backward compatibility: if you hava custom file handlers, you can
1184 use i_io_write() etc since they're available as macros in older
1185 versions of Imager.
1186
1187 - eliminate the final remnants of io_glue_commit_types().
1188
1189 - bump IMAGER_API_VERSION, since the above may break assumptions.
1190
1191 - removed the long unused i_gen_reader() and i_gen_writer() utility
1192 functions.

1255Development release as a sanity check for the types re-work.
8d14daab
TC
1256
1257Massive types re-work:
1258
1259 - the type used internally for pixel co-ordinates and image sizes is
1260 now 64-bit on 64-bit platforms (at least sane ones).
1261
1262 - size_t is now used consistently for memory block sizes.
1263
1264 - since this changes the binary interface, the Imager API version has
1265 been incremented. Any module that uses the API will need to be
1266 rebuilt. In most cases that will be enough, but calls to any APIs
1267 that take a pointer to image sizes may need source changes.
1268
1269 - you should be able to create very large images on 64-bit systems,
1270 if you have enough memory. Successfully created a 32768 x 49192 x
1271 3 channel image, filled with a tiled image and scaled it. The
1272 unscaled image was also successfully saved to a JPEG.
1273
1274 - check the image size before attempting to write BMP, GIF, JPEG,
1275 PNG, SGI, TGA, TIFF images.
1276
1277 - correctly handle reading TGA images over 32767 pixels wide or tall.
1278
1279Incidental changes:
1280
1281 - the gif_left and gif_top tags are now clamped to non-negative
1282 values when writing a GIF image.
1283
1284 - removed dead callback read/write code
1285
1286The default maximum memory size when reading files is now 1G.

1753 - an integer division meant that preview scaling to below 1 pixel
1754 wide or high (which isn't too useful anyway) was calculating using
1755 NaNs on most platforms, and causing an exception on others.
1756 Thanks to David Cantrell for producing a backtrace of the crash on
1757 his Alpha-NetBSD CPAN test box which made it possible to track this
1758 down.

1896 - Possible security issue: The floating point sample path for image

1905
1906 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1907 resulting in a SIGSEGV when attempting to scale an image to a size
1908 too large to fit in memory. This is a NULL pointer access issue,
1909 not a buffer overflow.

1911 scale_calculate() (and hence scale()) will now fail if any of the

1924This release primarily contains changes to improve ease of use -
1925rather than you having to convert images to the appropriate number of

1928release.

TC
1933 - moved the imtoc.perl code into Imager::Preprocess
1934
1935 - paste() and rubthrough() now adapt the source image data to the
1936 destination, so you can now safely paste/rubthrough from greyscale
1937 images to color images or back, or from alpha channel images to
1938 noalpha channels or back.
1939 https://rt.cpan.org/Ticket/Display.html?id=30908
1940
1941 - rubthrough() now falls back to pasting when the source doesn't have
1942 an alpha channel. This effectively treats the source as having a
1943 max alpha channel, the right thing to do.
1944 http://rt.cpan.org/Ticket/Display.html?id=29944
1945
1946 - re-worked most of the area filling code to use a common set of
1947 functions when filling.
1948 Corrected normal combine mode.
1949 Rewrote most of the combine modes to match the way the SVG draft
1950 defines them with respect to a translucent source and destination.
1951 Added tests for translucent source and destination.
1952 Added tests to check 8-bit/sample and double/sample combines work
1953 similarly.

1991
1992 - handling of the left-over bit for 16-bit/pixel TGA images has been
1993 changed to match the behaviour of the GIMP. Previously the bit
1994 being set was treated as an opaque pixel, but one user reported a
1995 problem with loading such an image. I haven't been able to find any
1996 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1997 I'll match it's behaviour. See issue 114913 in the GIMP's
1998 bugzilla.

2008 - the old dynaload code used Mach API functions to load dynamic
2009 libraries on Mac OS X. These APIs have been deprecated in OS X
2010 10.5 and were causing some build problems.

2012 will need version 10.3 or later of OS X.

2161Bug fixes:
2162
2163 - in some cases it's possible for giflib/libungif to return color
2164 indexes outside the range of colors defined by the image's palette.
2165 We now expand the palette to match the indexes used.
2166 Thanks to Gabriel Vasseur for reporting this.

2171 - to avoid confusion, channels not present in the image are returned as
2172 zero by getscanline(). This has no effect on the C level i_glin()

2174 channels.

2316Imager 0.55 - 16 Dec 2006
2317===========
2318
2319This is primarily a bug fix release.
2320
2321Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2322
2323There is one new feature:
2324
2325 - the Win32 font driver now supports UTF8 (RT 22166)
2326 http://www.cpanforum.com/threads/3276
2327 http://rt.cpan.org/Ticket/Display.html?id=22166
2328
2329Several bugs were fixed:
2330
2331 - the string() method would not output the string "0"
2332 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2333
2334 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2335 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2336
2337 - the gif_disposal and gif_user_input tags weren't being read from
2338 the file correctly
2339 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2340
2341 - gif.c was failing to build under MSVC
2342 http://rt.cpan.org/Ticket/Display.html?id=23922
2343
2344 - in some cases strings passed to the string() method were treated as
2345 terminated by NUL (chr 0)
2346 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2347
2348 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2349 that's the default build name for zlib on Win32.
2350 http://rt.cpan.org/Ticket/Display.html?id=23064
2351
2352 - search $Config{incpath} for headers too, which we should have been
2353 doing all along.
2354
2355Win32 font driver fixes:
2356
2357 - the global descent value from bounding box was the wrong sign
2358 http://www.cpanforum.com/threads/3276
2359
2360 - if the first or last glyph overflowed the left or right side of the
2361 advance width they would be clipped
2362
2363
2364Imager 0.54 - 14 Sep 2006
2365===========
2366
2367This is primarily a feature release:
2368
2369 - a new qtype value 'mixing' has been added to the scale()
2370 method. This is faster than 'normal', slower than 'preview'. This
2371 is based on the method used by pnmscale, and seems to produce less
2372 blurry results than normal.
2373 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2374
2375 - the rubthrough() method can now render onto images with an alpha
2376 channel.
2377 http://rt.cpan.org/Ticket/Display.html?id=20678
2378
2379 - the read_multi() method now falls back to calling doing a single
2380 image read via the read() method and write_multi() will now fall
2381 back to calling write() if a single image is supplied. This means
2382 you can simply call the read_multi() or write_multi() functions
2383 without having to check if the type is formatted by that method.
2384 http://rt.cpan.org/Ticket/Display.html?id=19457
2385 http://rt.cpan.org/Ticket/Display.html?id=19458
2386
2387 - the GIF loop extension can now be written. If you don't have
2388 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2389 should upgrade.
2390 http://rt.cpan.org/Ticket/Display.html?id=21185
2391
2392 - getscanline() and setscanline() can now read/write palette index
2393 based data from/to the image for paletted images, by setting type to
2394 'index'.
2395 http://rt.cpan.org/Ticket/Display.html?id=20338
2396
2397 - we no longer hassle you to disable GIF support
2398 http://rt.cpan.org/Ticket/Display.html?id=20687
2399
2400 - minor documentation fixes
2401
2402
2403Imager 0.53 - 26 Jul 2006
2404===========
2405
2406This is a bugfix release.
2407
2408Some test code was left in a code path not covered by the test
2409suite. A test was added to cover this code path and the test code was
2410removed.

2413
2414Imager 0.52 - 25 Jul 2006
2415===========
2416
2417This is primarily a feature release, but contains a fair few bug
2418fixes, new features:
2419
2420 - ability to read and write MS Windows ICO and CUR files
2421
2422 - you can now add file format plugins to support new file formats
2423
2424 - add POD coverage tests
2425
2426 - setcolors() and addcolors() now accept color names and so on
2427 instead of requiring Imager::Color objects.
2428 http://rt.cpan.org/Ticket/Display.html?id=20056
2429
2430 - flood_fill() can now fill to a specified border color instead of
2431 just to the area the same color as the seed.
2432 http://rt.cpan.org/Ticket/Display.html?id=19618
2433
2434
2435Bug fixes:
2436
2437 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2438 calculating the advance width.
2439 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2440
2441 - bounding_box for the T1 driver wasn't including leading and
2442 trailing spaces in the bounding box as the other drivers did, it also
2443 produced strange results for empty strings or strings containing only
2444 spaces
2445
2446 - when reading CMYK jpeg images they were being transferred to the
2447 image object as is, producing a four channel image. It only looked ok
2448 due to an old still unfixed Photoshop bug. We now convert from the
2449 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2450 http://rt.cpan.org/Ticket/Display.html?id=20416
2451
2452 - reading a CYMK TIFF would result in a 4 channel image, reading any
2453 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2454 result in an error.
2455 http://rt.cpan.org/Ticket/Display.html?id=20415
2456
2457 - added /usr/local/include to the default include search path, since
2458 we were already searching /usr/local/lib for libraries.
2459
2460And various minor fixes and documentation updates.
2461
2462
2463Imager 0.51 - 23 Apr 2006
2464===========
2465

2467 a crash
2468 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2469
2470 - fix mis-processing of the src_maxx and src_maxy parameters of the

2483 or 4 channel image to jpeg or a 2 channel image to tga where the
2484 output is an in-memeory buffer.
