1791cbdb
TC
3Coverity finally finished a build, fix a few problems:
4
8445279e
TC
5High severity:
6
1791cbdb 7 - reading a color-mapped TGA file with an id string would cause a
8445279e 8 double-free if the palette was truncated. CID 185317.
1791cbdb 9
6494c395
TC
10 - mixing scaling to sizes where the accumulator row, the working
11 output row or the working input row didn't fit into the address
12 space could result in memory leaks. This can probably only be
8445279e 13 reproduced on very wide floating-point sample images. CID 185318.
6494c395 14
fc24ca5f 15 - convert an array style function parameter pointer to pointer style
3d7b055c 16 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 17 CID 185343.
3d7b055c 18
8445279e 19 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 20
20c297d4 21 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 22 implementation. CID 185303.
20c297d4 23
fc24ca5f 24 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 25 drawing (it should always end up being set.) CID 185341.
fc24ca5f 26
f7675b46 27 - addi style makemap could potentially read one past the end of an
8445279e 28 array. CID 185337.
f7675b46 29
58ec1fde
TC
30 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
31 would result in read beyond the end of the built-in hatch array.
32 Negative values (which Coverity didn't complain about) could also
8445279e 33 cause problems. CID 185331.
58ec1fde 34
b7346865
TC
35 - the Imager::Color set_internal() interal method no longer
36 calls the over-complicated ICL_set_internal() (which is retained
37 only for the old API.) Coverity complained that this leaked, but
38 this could only occur with an invalid (NULL pointer) color object.
8445279e 39 CID 185323.
b7346865 40
785364c1
TC
41 - the underlying implementation of the map() method could read before
42 the beginning on an allocated array if supplied with inconsistent
43 parameters, which Coverity complained about. No Imager code calls
44 that function with inconsistent parameters, but a
8445279e 45 belt-and-suspenders check was added. CID 185315.
785364c1 46
eb7e48c9
TC
47 - Coverity complained a call to i_getcolors(), used by the
48 implementation of the is_bilevel() method could leave the fetched
8445279e 49 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 50
c1c8b1e9
TC
51 - a numeric combining mode of 13 (eg. as a parameter to
52 Imager::Fill->new())could cause an invalid array read in
53 i_get_combine() due to a fencepost error in validating the combine
8445279e 54 number. CID 185299.
c1c8b1e9 55
c4fd43be
TC
56
57
58 - avoid an unneeded EXTEND() call when the FT1 has_chars()
59 implementation returns 0. CID 185350.
60
61 - avoid accessing a possibly NULL map from MakeMapObject() in a
62 logging call. (GIF) CID 185296.
63
4615ad8d
TC
64 - gradgen() allocated the wrong amount of space (always too much) for
65 the color array. CID 185291.
66
ea3099db
TC
67 - avoid dead code in i_tt_glyph_names(). CID 185321.

TC
69Imager 1.008 - 31 Dec 2018
70============
71
75e155e1 72 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
73 This allows file formats that store EXIF data as blobs similarly
74 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 75
b5bbf161 76 - added some more file extensions to image file type mappings
75e155e1
TC
77
78 - added add_type_extensions() class method
79
b5bbf161 80Imager 1.007 - 24 Nov 2018

a9fa5463
TC
83 - add png_compression_level tag for writing PNG files.

TC
92 - improve error reporting for the polygon() method
93

TC
94Imager 1.006 - 26 Aug 2017
95============
96
ba7ddbae
TC
97 - the internal i_errors() function now correctly allocates the stack
98 space needed for its result.
99 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
100
101 - t/100-base/020-color.t now uses Imager::Test's test functions
102 instead of its own.
103 https://rt.cpan.org/Ticket/Display.html?id=111993
104
344dda51
TC
105 - write_multi() now returns an error result (a false value) if called
106 with a non-(Imager image object). Previously it would typically
107 crash.
108 https://rt.cpan.org/Ticket/Display.html?id=117878
109
110 - improve the documentation of the jpegquality parameter when
111 writing JPEG files.
112
113 - add code to mitigate CVE-2016-1238, Imager will no longer search the
114 default current directory entry in @INC when searching for file
115 format support modules.

117Imager 1.005 - 16 Apr 2016
118============
119
120It's now been ten years since I switched to the new Changes file in
121release 0.55.
122
cd0109d8
TC
123 - revert the ivdformat probes, they don't work as is and trying to
124 fix them is too much work for now.
125
6f1cbfed
TC
126Imager 1.004_004 - 15 Apr 2016
127================
128
9c45cc49
TC
129 - test that the ivdformat from Config is correct and look for a valid
130 one if it isn't.
131 For the strange Win32 failures.
132
133 - fix a copy and paste error in pod in samples/samp-form.cgi
134
5cea6ea1
TC
135Imager 1.004_003 - 23 Mar 2016
136================
137
bd2d657d
TC
138 - add some extra error reporting to the I/O layers tests, this might
139 help catch a failure seen on Win32.

TC
142Imager 1.004_002 - 20 Mar 2016
143================
144
735b3e7b
TC
145 - don't use the seek() method on opened() handles in
146 t/200-file/400-basic.t. In older versions of perl such handles are
147 only IO::Handle objects, not IO::File, and don't have a seek()
148 method.

TC
150Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
151================
152
08914ed1
TC
153 - re-work the t/200-file/400-basic.t to correctly handle failures
154 It's custom ok() function didn't have a prototype and didn't use scalar().
155 This caused ok() to use the note instead of the value being tested when
156 the method called returned an empty list. For an example of the problem
e6226ce5 157 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 158
a2791e47
TC
159 - remove some noise from when Imager tried to work with bugs in old
160 versions of giflib. I can't do much about the new bugs.
08914ed1 161
e6226ce5
TC
162 - the new autolevels filter (Imager 0.99) used an integer for the
163 sample scaling factor which caused the top output level to be too
164 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
165 https://rt.cpan.org/Ticket/Display.html?id=111871
166
e6226ce5 167 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
168 minimum and maximum luminance from the histogram. This slightly
169 reduced the contrast of the output image.
170 https://rt.cpan.org/Ticket/Display.html?id=111871
171
172 - the new autolevels filter now uses a lookup table for 8-bit images
173 to avoid a floating point multiply for each sample.
174 https://rt.cpan.org/Ticket/Display.html?id=111871
175
e6226ce5
TC
176 - fixed several memory leaks detected by valgrind:
177
178 - addcolors() leaked the temporary array of colors supplied to the
179 internal API
180
181 - make_palette() leaked the temporary image array (not the images
182 themselves) passed to the internal API.
183
184 - combine()/i_combine() leaked its working row buffers
185
186 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
187 buffer if there were too many colors
188
189 - getcolorcount()/i_count_colors() leaked the sample buffer if
190 there were too many colors.
191
192 - the nearest_color filter (undocumented until I find a use for it)
193 leaked both temporaries passed to the API and internal buffers
194
a2791e47
TC
195 - the internal process of upgrading a paletted image to a direct
196 color image would leak a context object reference count.
197
198 - a write failure when writing to a GIF file could leak memory.
199
200 - failing to write to a 1-bit/pixel ICO image could leak memory.
201
202 - Imager no longer deliberately leaks the context object from the
203 initial thread. This was done to ensure there was always a context
204 object available, but the code that needed that now handles the
205 lack correctly,
206
e6226ce5
TC
207 - fixed some uninitialized memory usage detected by valgrind:
208
209 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
210 i_matrix_transform_bg() didn't initialize a working color value
211 if there was zero pixel coverage.
212
213 - i_ft2_cp() didn't initialize the complete color when producing an
214 intermediate image. This caused uninitialized value usage when
215 logging the color.

TC
217Imager 1.004 - 8 Nov 2015
218============
219
5ebfb369
TC
220 - Imager::Color::Table is now pre-loaded by the preload() method.
221 https://rt.cpan.org/Ticket/Display.html?id=104896
222
223 - fix an assertion triggered under perl 5.23.4.
224 Thanks to A. Sinan Unur for the report and the patch.
225
7b638aba
TC
226 - Imager->new can now be used to read raw image files.
227 https://rt.cpan.org/Ticket/Display.html?id=106836
f7160b21 228 Thanks to Richard Kelsch for reporting this.
7b638aba
TC
229
230 - deal with output changes from Pod::Spell
231 https://github.com/perl-pod/Pod-Spell/issues/21
232
0d1baac8
TC
233Imager 1.003 - 12 May 2015
234============
235
0fda3cfd
TC
236 - update 1.002 release notes to include the center change for filled
237 circle drawing.
238
239 - flood_fill() would escape beyond a 4-connected space under some
240 circumstances.
241 Added many more flood_fill() tests.
242 https://rt.cpan.org/Ticket/Display.html?id=103786
243
647a47c9
TC
244Imager 1.002 - 3 Apr 2015
245============
246
334b8922
TC
247 - drawing anti-aliased filled circles is now 10 to 50 times faster
248 depending on the size of the circle.
0fda3cfd
TC
249 This also changed the center from being the center of the pixel to
250 being the top left of the pixel to match the filled arcs drawn by
251 arc().
334b8922
TC
252 https://rt.cpan.org/Ticket/Display.html?id=101682
253
254 - enhancements to polygon filling:
255
256 - added a mode parameter to control how overlapping regions behave
257
258 - added a polypolygon() method to fill more than one polygon at a
259 time
260
261 - polygon filling is now exposed through the API.
262
45c8e262
TC
263 - added colormodel(), alphachannel() and colorchannels() methods.
264 These were added for two reasons:
265
266 - a future version of Imager may allow the number of channels in
267 an image to not directly represent the color model of an image.
268 eg. a greyscale TIFF image with multiple alpha channels.
269
270 - a future version of Imager may allow an image to be read without
271 translation, for example a TIFF file that contains measurements
0fda3cfd 272 from an instrument. Currently Imager transforms the samples into
d96c4de8 273 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
274 the value back.
275
276 An untranslated image would be unusable as image data, so
277 colormodel() would return "unknown" in this case.
278
279 Similarly a CMYK image might be returned as an "unknown" color
280 model image, if the caller chooses to disable translation to
281 RGB.

283Imager 1.001 - 2 Jan 2015
284============
285
aca60e01
TC
286 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
287 Thanks to Slaven Rezic for the report and the patch.
288 https://rt.cpan.org/Public/Bug/Display.html?id=98234
289
0df260f6
TC
290 - GIF: clean-up a test file if the test for the giflib 4.2.0 file
291 version bug fails.
292
293 - fix Imager::Matrix2d::rotate()'s centre point handling
294 https://rt.cpan.org/Public/Bug/Display.html?id=99959
295
296 - ICO: don't apply the icon mask to images with an alpha channel by
297 default
298 https://rt.cpan.org/Public/Bug/Display.html?id=99507
299
56605f3f
TC
300 - make verbose probing output more verbose
301
f74bd978
TC
302 - use Imager::Probe to probe for freetype 1.x
303 https://rt.cpan.org/Ticket/Display.html?id=100502
304
305 - The --enable and --disable parameters to the top-level Makefile.PL
306 work again.
307
c7f06039
TC
308 - update the bundled/modified Devel::CheckLib to handle the gcc-4
309 symlink on Cygwin

311Imager 1.000 - 28 Jul 2014
312============
313
314There's nothing special about Imager 1.000, it's just another release.
315
fa3dac1d
TC
316 - fix the skip check for the iolayer qr// buffer test
317
318 - improve error reporting for the iolayer test failing on a small
319 number of Win32 CPAN testers
320
35349dba
TC
321Imager 0.99_02 - 21 Jul 2014
322==============
323
5dab5b9a
TC
324 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
325 the blue channel in the generated palette, and allow each color
326 component to be in the range 100..255 instead of just 100..254.
327 Thanks to Ralf Neubauer.
328 https://rt.cpan.org/Ticket/Display.html?id=97086
329
330 - revert "improved the XS for i_io_read() and i_io_raw_read()"
331 This caused problems with older perls and didn't provide much of a
332 performance improvement.
333
5bf25bc2 334 - support Inline 0.57 and later.
6d47a6af 335 Inline 0.57 changed the "with" interface.
5bf25bc2
TC
336 https://rt.cpan.org/Ticket/Display.html?id=97108
337
6d47a6af
TC
338 - don't define our own MAXINT macro, it conflicts with windows header
339 files and in a few places it was the wrong value to use anyway.
340 https://rt.cpan.org/Ticket/Display.html?id=96425

TC
342Imager 0.99_01 - 29 Jun 2014
343==============
344
7b486870
TC
345 - GIF: add support for giflib 5.1.0, which added error code pointer
346 parameters to EGifCloseFile() and DGifCloseFile().
347 https://rt.cpan.org/Ticket/Display.html?id=96756
348
349 - GIF: avoid a double-free when do_write() fails.
350
28104a85 351 - fix SV type probing to work on perl before 5.12. Broken in 0.99.
ea87cee9
TC
352 https://rt.cpan.org/Ticket/Display.html?id=96761
353
df04d4b3
TC
354 - PNG: skip the benign error test before libpng 1.6.0, since the
355 error we're testing didn't exist before 1.6.0.

358Imager 0.99 - 25 Jun 2014
359===========
360
dce1523b
TC
361 - Imager::IO->new_buffer() (and hence Imager->read()'s data
362 parameter) now accepts a reference to a scalar as well as just a
363 plain scalar.
6a160bce 364 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
365
366 - Imager::IO->new_buffer() now always makes a copy of the passed in
367 buffer to avoid problems with temporary objects used for the return
368 value of SvPVbyte().
6a160bce 369 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 370
c757e211
TC
371 - improved the XS for i_io_read() and i_io_raw_read()
372 https://rt.cpan.org/Ticket/Display.html?id=92738
373
374 - load plugins from absolute paths on Android
375 Thanks to Brian Fraser.
376 https://rt.cpan.org/Ticket/Display.html?id=93272
377
6a160bce
TC
378 - added the jpeg_optimize parameter for writing JPEG files. This can
379 significantly reduce file sizes, but uses more memory and time.
380 https://rt.cpan.org/Ticket/Display.html?id=94292
381
14fd9e5d
TC
382 - the autolevels filter now works on the luminosity of the image
383 rather then working per channel. The old autolevels filter is
384 still available as "autolevels_skew".
385 https://rt.cpan.org/Ticket/Display.html?id=94413
386
75d54149
TC
387 - Imager::File::PNG now supports libpng 1.6.10.
388 1.6.10 changed CRC errors from benign errors to normal errors,
389 which broke the test which used CRC errors to check for benign
390 error support. Switched to using a 1-bit grey-scale image with a
391 palette to test for benign errors.
392 https://rt.cpan.org/Ticket/Display.html?id=94717

TC
394Imager 0.98 - 3 Jan 2014
395===========
396
f84f86a2
TC
397Incompatible changes:
398
399 - the return value of setpixel() has changed.
400
401 Previously the return values for undrawable pixels vs caller errors
402 changed depending on whether you used the multiple pixel calling
403 mechanism, or the single pixel mechanism.
404
405 Now:
406
407 - for an invalid parameter, such as an unknown colour, or missing
408 parameter, an empty list (or undef in scalar context) is
409 returned, and errstr() is set,
410
411 - otherwise the number of pixels drawn is returned. If none of
412 the pixels could be drawn (they were all outside the image), "0
413 but true" is returned.
414
415 https://rt.cpan.org/Ticket/Display.html?id=87650
416
417Other changes:
418
6ba09ab9
TC
419 - when drawing on an image with an alpha channel where the source
420 minimum is greater than zero, Imager would read from beyond the end
421 of a malloc() allocated buffer. In rare circumstances this could
422 lead to some of the source image not being written to the target
423 image, or possibly to a segmentation fault.
424 I don't believe this has any security concerns beyond that.
425
0d052fd9
TC
426 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
427 text drawn would be nonsense. This would also read beyond the end
428 of a malloced buffer.
429
13671b17
TC
430 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
431 truncated early.
432 https://rt.cpan.org/Ticket/Display.html?id=88993
433
d6f4e964
TC
434 - Imager::Font::Wrap no longer requires the image parameter.
435 https://rt.cpan.org/Ticket/Display.html?id=87338
436
f84f86a2
TC
437 - a documentation typo fix in Imager::Transformations
438 Thanks to Adrian Yee.

479 Mixed SampleFormat are handled incorrectly, since libtiff returns
480 only the first SampleFormat value, and an image with both an alpha
481 channel and SampleFormat = 2 for color channels probably has a
482 different SampleFormat for the alpha channel.

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

741Other changes:
742
743 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
744 internals, those names only matter for the XS interface.
745
746 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
747 the API level compiled into a loadable module such as
748 Imager::File::GIF doesn't match that of Imager. Previously it
749 could be difficult to determine exactly which module was failing to
750 load.
751 https://rt.cpan.org/Ticket/Display.html?id=77173
752
753 - added Imager->check_file_limits() as an interface to the
754 i_int_check_image_file_limits() API.
755

TC
771 - when downconverting samples (eg. from floating point to 8 bit)
772 Imager now rounds the sample value rather than attempting to
773 allocate input values over output values equally. The old
774 behaviour had the probably surprising effect of converting a
775 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
776 2.
777 This may result in slightly different 8 or 16-bit output images.
778
e2a86bac
TC
779 - BI_BITFIELD BMP images were handled incorrectly, both in
780 incorrectly calculating the space required for the masks and in
781 processing the image data itself.
782 https://rt.cpan.org/Ticket/Display.html?id=76736
783
784 - some odd width BMP BI_RLE4 images use run lengths that run one off
785 the edge of the image. Imager now allows this, discarding the
786 extra column.
787
788 - odd length RLE4 runs in BMP images were decoded incorrectly.

790 - pkg-config could sometimes return a library that was in a directory

793 EU::MM can find the library, and if not, search our configured

798 common for static linking, eg. libpng requires libz.
799 https://rt.cpan.org/Ticket/Display.html?id=74043
800
801 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.

804 handle a statically linked libpng.
805 https://rt.cpan.org/Ticket/Display.html?id=74043
806
807 - if a probe includes testcode, Imager::Probe now checks that code as
808 part of the process of checking each configuration rather than as a
809 post test of the found configuration. This allows alternate
810 configurations to be checked if a matching but non-working
811 configuration is found.

888 write 8-bit or floating point samples from a scalar or array
889 reference. This adds i_psamp() and i_psampf() to the C level API.
890
891 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
892 changed to make better use of the typemap, but these aren't part of
893 the perl level API anyway. There were no changes to the C level
894 interfaces to these functions.

1049 - io_glue I/O buffering re-work:
1050
1051 - reorganize io_glue to do it's own buffering by default
1052
1053 - the unbuffered functions are available as i_io_raw_read() (or
1054 raw_read() from perl) etc but are not recommended for typical
1055 use.
1056
1057 - use the new i_io_peekn() when checking for file magic to avoid
1058 seek, allowing Imager to detect the file type and read the file
1059 from an unseekable stream (for formats that don't use random
1060 access)
1061
1062 - added several new I/O layer API functions.

1064 - fix the TGA performance problem, most noticably on Win32
1065 https://rt.cpan.org/Ticket/Display.html?id=70037

1067 - TIFF now uses wrapper functions of the correct types to avoid casts
1068 https://rt.cpan.org/Ticket/Display.html?id=69912
1069
1070 - the callback IO object did its own buffering, controlled by the
1071 maxbuffer parameter supplied to the read() and write() methods.
1072 This buffering has been removed, to avoid redundancy with the
1073 common io_glue buffering. This also avoids a bug in that code
1074 which could rarely pass a zero length to the read callback and
1075 then panic about the result.
1076
1077 - the callback IO object now tests the result of calling the close
1078 callback, which should return true for success.
1079
1080 - the PNM reader did its own buffering. This buffering has been
1081 removed to avoid redundancy with the common io_glue buffering.
1082
1083 - previously the read handlers for fd and callback I/O layers would
1084 call the underlying interface (POSIX read or your supplied callback)
1085 until it filled the buffer. It now only makes one call.
1086
1087 - added public constructors for I/O layer objects (see Imager::IO)
1088
1089 - all core file handlers now use the i_io_foo() wrappers to gain
1090 access to buffered I/O rather than calling the I/O layer
1091 callbacks directly.
1092
1093 - all core file handlers now check for error on close.
1094
1095 - Backward compatibility: if you hava custom file handlers, you can
1096 use i_io_write() etc since they're available as macros in older
1097 versions of Imager.
1098
1099 - eliminate the final remnants of io_glue_commit_types().
1100
1101 - bump IMAGER_API_VERSION, since the above may break assumptions.
1102
1103 - removed the long unused i_gen_reader() and i_gen_writer() utility
1104 functions.

TC
1168
1169Massive types re-work:
1170
1171 - the type used internally for pixel co-ordinates and image sizes is
1172 now 64-bit on 64-bit platforms (at least sane ones).
1173
1174 - size_t is now used consistently for memory block sizes.
1175
1176 - since this changes the binary interface, the Imager API version has
1177 been incremented. Any module that uses the API will need to be
1178 rebuilt. In most cases that will be enough, but calls to any APIs
1179 that take a pointer to image sizes may need source changes.
1180
1181 - you should be able to create very large images on 64-bit systems,
1182 if you have enough memory. Successfully created a 32768 x 49192 x
1183 3 channel image, filled with a tiled image and scaled it. The
1184 unscaled image was also successfully saved to a JPEG.
1185
1186 - check the image size before attempting to write BMP, GIF, JPEG,
1187 PNG, SGI, TGA, TIFF images.
1188
1189 - correctly handle reading TGA images over 32767 pixels wide or tall.
1190
1191Incidental changes:
1192
1193 - the gif_left and gif_top tags are now clamped to non-negative
1194 values when writing a GIF image.
1195
1196 - removed dead callback read/write code
1197
1198The default maximum memory size when reading files is now 1G.

1808 - Possible security issue: The floating point sample path for image

1818 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1819 resulting in a SIGSEGV when attempting to scale an image to a size
1820 too large to fit in memory. This is a NULL pointer access issue,
1821 not a buffer overflow.
1822 Added a check for the failure.
1823 scale_calculate() (and hence scale()) will now fail if any of the
1824 scale size parameters are a reference.

1836This release primarily contains changes to improve ease of use -
1837rather than you having to convert images to the appropriate number of
1838channels, Imager handles it internally. How to handle drawing colors
1839and the default combine mode is a thornier problem left for some other
1840release.

TC
1845 - moved the imtoc.perl code into Imager::Preprocess
1846
1847 - paste() and rubthrough() now adapt the source image data to the
1848 destination, so you can now safely paste/rubthrough from greyscale
1849 images to color images or back, or from alpha channel images to
1850 noalpha channels or back.
1851 https://rt.cpan.org/Ticket/Display.html?id=30908
1852
1853 - rubthrough() now falls back to pasting when the source doesn't have
1854 an alpha channel. This effectively treats the source as having a
1855 max alpha channel, the right thing to do.
1856 http://rt.cpan.org/Ticket/Display.html?id=29944
1857
1858 - re-worked most of the area filling code to use a common set of
1859 functions when filling.
1860 Corrected normal combine mode.
1861 Rewrote most of the combine modes to match the way the SVG draft
1862 defines them with respect to a translucent source and destination.
1863 Added tests for translucent source and destination.
1864 Added tests to check 8-bit/sample and double/sample combines work
1865 similarly.

1903
1904 - handling of the left-over bit for 16-bit/pixel TGA images has been
1905 changed to match the behaviour of the GIMP. Previously the bit
1906 being set was treated as an opaque pixel, but one user reported a
1907 problem with loading such an image. I haven't been able to find any
1908 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1909 I'll match it's behaviour. See issue 114913 in the GIMP's
1910 bugzilla.

1920 - the old dynaload code used Mach API functions to load dynamic
1921 libraries on Mac OS X. These APIs have been deprecated in OS X
1922 10.5 and were causing some build problems.

1924 will need version 10.3 or later of OS X.

2196Bug fixes:
2197
2198 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
2199 was returning an image object with an extra reference, this
2200 resulted in a memory leak.

2209 http://rt.cpan.org/Ticket/Display.html?id=8426
2210
2211 - previously, reading ASCII PBM files required spaces between samples,

2228Imager 0.55 - 16 Dec 2006
2229===========
2230
2231This is primarily a bug fix release.
2232
2233Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2234
2235There is one new feature:
2236
2237 - the Win32 font driver now supports UTF8 (RT 22166)
2238 http://www.cpanforum.com/threads/3276
2239 http://rt.cpan.org/Ticket/Display.html?id=22166
2240
2241Several bugs were fixed:
2242
2243 - the string() method would not output the string "0"
2244 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2245
2246 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2247 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2248
2249 - the gif_disposal and gif_user_input tags weren't being read from
2250 the file correctly
2251 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2252
2253 - gif.c was failing to build under MSVC
2254 http://rt.cpan.org/Ticket/Display.html?id=23922
2255
2256 - in some cases strings passed to the string() method were treated as
2257 terminated by NUL (chr 0)
2258 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2259
2260 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2261 that's the default build name for zlib on Win32.
2262 http://rt.cpan.org/Ticket/Display.html?id=23064
2263
2264 - search $Config{incpath} for headers too, which we should have been
2265 doing all along.
2266
2267Win32 font driver fixes:
2268
2269 - the global descent value from bounding box was the wrong sign
2270 http://www.cpanforum.com/threads/3276
2271
2272 - if the first or last glyph overflowed the left or right side of the
2273 advance width they would be clipped
2274
2275
2276Imager 0.54 - 14 Sep 2006
2277===========
2278
2279This is primarily a feature release:
2280
2281 - a new qtype value 'mixing' has been added to the scale()
2282 method. This is faster than 'normal', slower than 'preview'. This
2283 is based on the method used by pnmscale, and seems to produce less
2284 blurry results than normal.
2285 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2286
2287 - the rubthrough() method can now render onto images with an alpha
2288 channel.
2289 http://rt.cpan.org/Ticket/Display.html?id=20678
2290
2291 - the read_multi() method now falls back to calling doing a single
2292 image read via the read() method and write_multi() will now fall
2293 back to calling write() if a single image is supplied. This means
2294 you can simply call the read_multi() or write_multi() functions
2295 without having to check if the type is formatted by that method.
2296 http://rt.cpan.org/Ticket/Display.html?id=19457
2297 http://rt.cpan.org/Ticket/Display.html?id=19458
2298
2299 - the GIF loop extension can now be written. If you don't have
2300 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2301 should upgrade.
2302 http://rt.cpan.org/Ticket/Display.html?id=21185
2303
2304 - getscanline() and setscanline() can now read/write palette index
2305 based data from/to the image for paletted images, by setting type to
2306 'index'.
2307 http://rt.cpan.org/Ticket/Display.html?id=20338
2308
2309 - we no longer hassle you to disable GIF support
2310 http://rt.cpan.org/Ticket/Display.html?id=20687
2311
2312 - minor documentation fixes
2313
2314
2315Imager 0.53 - 26 Jul 2006
2316===========
2317
2318This is a bugfix release.
2319
2320Some test code was left in a code path not covered by the test
2321suite. A test was added to cover this code path and the test code was
2322removed.
2323http://rt.cpan.org/Public/Bug/Display.html?id=20705
2324
2325
2326Imager 0.52 - 25 Jul 2006
2327===========
2328
2329This is primarily a feature release, but contains a fair few bug
2330fixes, new features:
2331
2332 - ability to read and write MS Windows ICO and CUR files
2333
2334 - you can now add file format plugins to support new file formats
2335
2336 - add POD coverage tests
2337
2338 - setcolors() and addcolors() now accept color names and so on
2339 instead of requiring Imager::Color objects.
2340 http://rt.cpan.org/Ticket/Display.html?id=20056
2341
2342 - flood_fill() can now fill to a specified border color instead of
2343 just to the area the same color as the seed.
2344 http://rt.cpan.org/Ticket/Display.html?id=19618
2345
2346
2347Bug fixes:
2348
2349 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2350 calculating the advance width.
2351 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2352
2353 - bounding_box for the T1 driver wasn't including leading and
2354 trailing spaces in the bounding box as the other drivers did, it also
2355 produced strange results for empty strings or strings containing only
2356 spaces
2357
2358 - when reading CMYK jpeg images they were being transferred to the
2359 image object as is, producing a four channel image. It only looked ok
2360 due to an old still unfixed Photoshop bug. We now convert from the
2361 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2362 http://rt.cpan.org/Ticket/Display.html?id=20416
2363
2364 - reading a CYMK TIFF would result in a 4 channel image, reading any
2365 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2366 result in an error.
2367 http://rt.cpan.org/Ticket/Display.html?id=20415
2368
2369 - added /usr/local/include to the default include search path, since
2370 we were already searching /usr/local/lib for libraries.
2371
2372And various minor fixes and documentation updates.
2373
2374
2375Imager 0.51 - 23 Apr 2006

2378 - fix a validation bug when processing JPEG EXIF data that can cause
2379 a crash
2380 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2381
2382 - fix mis-processing of the src_maxx and src_maxy parameters of the
2383 paste() method
2384 http://rt.cpan.org/Public/Bug/Display.html?id=18712
2385
2386 - fix a problem in Imager's "smart" handling of the color parameter
2387 to various methods.
2388 http://rt.cpan.org/Public/Bug/Display.html?id=18561
2389
2390

2395 or 4 channel image to jpeg or a 2 channel image to tga where the
2396 output is an in-memeory buffer.
2397 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2398
2399 - fixes an incorrect pointer parameter in the PNG code
2400 http://rt.cpan.org/Public/Bug/Display.html?id=18051
