3General changes:
4
5 - to_paletted() and make_palette() now fail (with an error in
6 errstr()) if invalid quantization parameters are supplied.
7
8Coverity finally finished a build[1], fix a few problems:
1791cbdb 9
8445279e
TC
10High severity:
11
1791cbdb 12 - reading a color-mapped TGA file with an id string would cause a
8445279e 13 double-free if the palette was truncated. CID 185317.
1791cbdb 14
6494c395
TC
15 - mixing scaling to sizes where the accumulator row, the working
16 output row or the working input row didn't fit into the address
17 space could result in memory leaks. This can probably only be
8445279e 18 reproduced on very wide floating-point sample images. CID 185318.
6494c395 19
fc24ca5f 20 - convert an array style function parameter pointer to pointer style
3d7b055c 21 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 22 CID 185343.
3d7b055c 23
8445279e 24 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 25
20c297d4 26 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 27 implementation. CID 185303.
20c297d4 28
fc24ca5f 29 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 30 drawing (it should always end up being set.) CID 185341.
fc24ca5f 31
f7675b46 32 - addi style makemap could potentially read one past the end of an
8445279e 33 array. CID 185337.
f7675b46 34
58ec1fde
TC
35 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
36 would result in read beyond the end of the built-in hatch array.
37 Negative values (which Coverity didn't complain about) could also
8445279e 38 cause problems. CID 185331.
58ec1fde 39
b7346865
TC
40 - the Imager::Color set_internal() interal method no longer
41 calls the over-complicated ICL_set_internal() (which is retained
42 only for the old API.) Coverity complained that this leaked, but
43 this could only occur with an invalid (NULL pointer) color object.
8445279e 44 CID 185323.
b7346865 45
785364c1
TC
46 - the underlying implementation of the map() method could read before
47 the beginning on an allocated array if supplied with inconsistent
48 parameters, which Coverity complained about. No Imager code calls
49 that function with inconsistent parameters, but a
8445279e 50 belt-and-suspenders check was added. CID 185315.
785364c1 51
eb7e48c9
TC
52 - Coverity complained a call to i_getcolors(), used by the
53 implementation of the is_bilevel() method could leave the fetched
8445279e 54 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 55
c1c8b1e9
TC
56 - a numeric combining mode of 13 (eg. as a parameter to
57 Imager::Fill->new())could cause an invalid array read in
58 i_get_combine() due to a fencepost error in validating the combine
8445279e 59 number. CID 185299.
c1c8b1e9 60
c4fd43be
TC
61
62
63 - avoid an unneeded EXTEND() call when the FT1 has_chars()
64 implementation returns 0. CID 185350.
65
66 - avoid accessing a possibly NULL map from MakeMapObject() in a
67 logging call. (GIF) CID 185296.
68
4615ad8d
TC
69 - gradgen() allocated the wrong amount of space (always too much) for
70 the color array. CID 185291.
71
ea3099db
TC
72 - avoid dead code in i_tt_glyph_names(). CID 185321.
73
8b810590
TC
74 - avoid dead code in i_get_anonymous_color_histo(), which is the
75 implementation of getcolorusage(). CID 185327.
76
4eb9a521
TC
77 - avoid dead code in i_ft2_glyph_name(), which is the implementation
78 of glyph_names() for FT2. CID 185342.
79
c028aa12
TC
80 - avoid dead code in i_t1_glyph_names(), which is the implementation
81 of glyph_names() for T1. CID 185322.
82
e7772cea
TC
83 - avoid an unneeded EXTEND() call when the FT2 has_chars()
84 implementation returns 0. CID 185292.
85
596f3eee
TC
86 - the unpack code for ICO/CUR file handling could extend 32-bit
87 unsigned values to 64-bit signed. I believe this is harmless. CID
88 185319.
89
a2ca2b80
TC
90 - remove an unneeded check when terminating the stream for JPEG
91 writing. CID 185347.
92
56ce7446
TC
93 - skip an unneeded check when freeing the combine temp buffer in the
94 fountain filter. CID 185286.
95
96 - check the combine function pointer consistently rather than the
97 combine code in one place in the fountain filter.
98
a3b721bb
TC
99 - error diffusion now validates a custom error diffusion map and reports
100 an error if it's bad. CID 185288.
101
215d9ead
TC
102 - avoid discarding the value of i_io_getc() when scanning numbers in
103 pnm.c. CID 185293.
104
9ca939d0
TC
105 - handle failure to clone the log filehandle when cloning the Imager
106 context object on thread creation. CID 185294.
107
a3b721bb
TC
108[1] The first two build submissions ended up at the end of a ~400
109build queue, and seemed to have been cancelled by Coverity. A build
110submitted on NYE went through in minutes.

TC
112Imager 1.008 - 31 Dec 2018
113============
114
75e155e1 115 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
116 This allows file formats that store EXIF data as blobs similarly
117 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 118
b5bbf161 119 - added some more file extensions to image file type mappings
75e155e1
TC
120
121 - added add_type_extensions() class method

TC
137Imager 1.006 - 26 Aug 2017
138============
139
ba7ddbae
TC
140 - the internal i_errors() function now correctly allocates the stack
141 space needed for its result.
142 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
143
144 - t/100-base/020-color.t now uses Imager::Test's test functions
145 instead of its own.
146 https://rt.cpan.org/Ticket/Display.html?id=111993
147
344dda51
TC
148 - write_multi() now returns an error result (a false value) if called
149 with a non-(Imager image object). Previously it would typically
150 crash.
151 https://rt.cpan.org/Ticket/Display.html?id=117878
152
153 - improve the documentation of the jpegquality parameter when
154 writing JPEG files.
155
156 - add code to mitigate CVE-2016-1238, Imager will no longer search the
157 default current directory entry in @INC when searching for file
158 format support modules.

161============
162
163It's now been ten years since I switched to the new Changes file in
164release 0.55.
165
cd0109d8
TC
166 - revert the ivdformat probes, they don't work as is and trying to
167 fix them is too much work for now.
168
6f1cbfed
TC
169Imager 1.004_004 - 15 Apr 2016
170================
171
9c45cc49
TC
172 - test that the ivdformat from Config is correct and look for a valid
173 one if it isn't.
174 For the strange Win32 failures.
175
176 - fix a copy and paste error in pod in samples/samp-form.cgi
177

TC
178Imager 1.004_003 - 23 Mar 2016
179================
180
bd2d657d
TC
181 - add some extra error reporting to the I/O layers tests, this might
182 help catch a failure seen on Win32.

TC
185Imager 1.004_002 - 20 Mar 2016
186================
187
735b3e7b
TC
188 - don't use the seek() method on opened() handles in
189 t/200-file/400-basic.t. In older versions of perl such handles are
190 only IO::Handle objects, not IO::File, and don't have a seek()
191 method.

TC
193Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
194================
195
08914ed1
TC
196 - re-work the t/200-file/400-basic.t to correctly handle failures
197 It's custom ok() function didn't have a prototype and didn't use scalar().
198 This caused ok() to use the note instead of the value being tested when
199 the method called returned an empty list. For an example of the problem
e6226ce5 200 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 201
a2791e47
TC
202 - remove some noise from when Imager tried to work with bugs in old
203 versions of giflib. I can't do much about the new bugs.
08914ed1 204
e6226ce5
TC
205 - the new autolevels filter (Imager 0.99) used an integer for the
206 sample scaling factor which caused the top output level to be too
207 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
208 https://rt.cpan.org/Ticket/Display.html?id=111871
209
e6226ce5 210 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
211 minimum and maximum luminance from the histogram. This slightly
212 reduced the contrast of the output image.
213 https://rt.cpan.org/Ticket/Display.html?id=111871
214
215 - the new autolevels filter now uses a lookup table for 8-bit images
216 to avoid a floating point multiply for each sample.
217 https://rt.cpan.org/Ticket/Display.html?id=111871
218
e6226ce5
TC
219 - fixed several memory leaks detected by valgrind:
220
221 - addcolors() leaked the temporary array of colors supplied to the
222 internal API
223
224 - make_palette() leaked the temporary image array (not the images
225 themselves) passed to the internal API.
226
227 - combine()/i_combine() leaked its working row buffers
228
229 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
230 buffer if there were too many colors
231
232 - getcolorcount()/i_count_colors() leaked the sample buffer if
233 there were too many colors.
234
235 - the nearest_color filter (undocumented until I find a use for it)
236 leaked both temporaries passed to the API and internal buffers
237
a2791e47
TC
238 - the internal process of upgrading a paletted image to a direct
239 color image would leak a context object reference count.
240
241 - a write failure when writing to a GIF file could leak memory.
242
243 - failing to write to a 1-bit/pixel ICO image could leak memory.
244
245 - Imager no longer deliberately leaks the context object from the
246 initial thread. This was done to ensure there was always a context
247 object available, but the code that needed that now handles the
248 lack correctly,
249
e6226ce5
TC
250 - fixed some uninitialized memory usage detected by valgrind:
251
252 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
253 i_matrix_transform_bg() didn't initialize a working color value
254 if there was zero pixel coverage.
255
256 - i_ft2_cp() didn't initialize the complete color when producing an
257 intermediate image. This caused uninitialized value usage when
258 logging the color.

260Imager 1.004 - 8 Nov 2015
261============
262
5ebfb369
TC
263 - Imager::Color::Table is now pre-loaded by the preload() method.
264 https://rt.cpan.org/Ticket/Display.html?id=104896
265
266 - fix an assertion triggered under perl 5.23.4.
267 Thanks to A. Sinan Unur for the report and the patch.
268
7b638aba
TC
269 - Imager->new can now be used to read raw image files.

f7160b21 271 Thanks to Richard Kelsch for reporting this.
7b638aba
TC
272
273 - deal with output changes from Pod::Spell

TC
276Imager 1.003 - 12 May 2015
277============
278
0fda3cfd
TC
279 - update 1.002 release notes to include the center change for filled
280 circle drawing.
281
282 - flood_fill() would escape beyond a 4-connected space under some
283 circumstances.
284 Added many more flood_fill() tests.

TC
287Imager 1.002 - 3 Apr 2015
288============
289
334b8922
TC
290 - drawing anti-aliased filled circles is now 10 to 50 times faster
291 depending on the size of the circle.
0fda3cfd
TC
292 This also changed the center from being the center of the pixel to
293 being the top left of the pixel to match the filled arcs drawn by
294 arc().
334b8922
TC
295 https://rt.cpan.org/Ticket/Display.html?id=101682
296
297 - enhancements to polygon filling:
298
299 - added a mode parameter to control how overlapping regions behave
300
301 - added a polypolygon() method to fill more than one polygon at a
302 time
303
304 - polygon filling is now exposed through the API.
305
45c8e262
TC
306 - added colormodel(), alphachannel() and colorchannels() methods.
307 These were added for two reasons:
308
309 - a future version of Imager may allow the number of channels in
310 an image to not directly represent the color model of an image.
311 eg. a greyscale TIFF image with multiple alpha channels.
312
313 - a future version of Imager may allow an image to be read without
314 translation, for example a TIFF file that contains measurements
0fda3cfd 315 from an instrument. Currently Imager transforms the samples into
d96c4de8 316 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
317 the value back.
318
319 An untranslated image would be unusable as image data, so
320 colormodel() would return "unknown" in this case.
321
322 Similarly a CMYK image might be returned as an "unknown" color
323 model image, if the caller chooses to disable translation to
324 RGB.

TC
364Imager 0.99_02 - 21 Jul 2014
365==============
366
5dab5b9a
TC
367 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
368 the blue channel in the generated palette, and allow each color
369 component to be in the range 100..255 instead of just 100..254.
370 Thanks to Ralf Neubauer.
371 https://rt.cpan.org/Ticket/Display.html?id=97086
372
373 - revert "improved the XS for i_io_read() and i_io_raw_read()"
374 This caused problems with older perls and didn't provide much of a
375 performance improvement.
376
5bf25bc2 377 - support Inline 0.57 and later.
6d47a6af 378 Inline 0.57 changed the "with" interface.

401Imager 0.99 - 25 Jun 2014
402===========
403
dce1523b
TC
404 - Imager::IO->new_buffer() (and hence Imager->read()'s data
405 parameter) now accepts a reference to a scalar as well as just a
406 plain scalar.
6a160bce 407 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
408
409 - Imager::IO->new_buffer() now always makes a copy of the passed in
410 buffer to avoid problems with temporary objects used for the return
411 value of SvPVbyte().
6a160bce 412 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 413
c757e211
TC
414 - improved the XS for i_io_read() and i_io_raw_read()
415 https://rt.cpan.org/Ticket/Display.html?id=92738
416
417 - load plugins from absolute paths on Android
418 Thanks to Brian Fraser.
419 https://rt.cpan.org/Ticket/Display.html?id=93272
420
6a160bce
TC
421 - added the jpeg_optimize parameter for writing JPEG files. This can
422 significantly reduce file sizes, but uses more memory and time.
423 https://rt.cpan.org/Ticket/Display.html?id=94292
424
14fd9e5d
TC
425 - the autolevels filter now works on the luminosity of the image
426 rather then working per channel. The old autolevels filter is
427 still available as "autolevels_skew".
428 https://rt.cpan.org/Ticket/Display.html?id=94413
429
75d54149
TC
430 - Imager::File::PNG now supports libpng 1.6.10.
431 1.6.10 changed CRC errors from benign errors to normal errors,

440Incompatible changes:
441
442 - the return value of setpixel() has changed.
443
444 Previously the return values for undrawable pixels vs caller errors
445 changed depending on whether you used the multiple pixel calling
446 mechanism, or the single pixel mechanism.
447
448 Now:
449
450 - for an invalid parameter, such as an unknown colour, or missing
451 parameter, an empty list (or undef in scalar context) is
452 returned, and errstr() is set,
453
454 - otherwise the number of pixels drawn is returned. If none of
455 the pixels could be drawn (they were all outside the image), "0
456 but true" is returned.

460Other changes:

TC
462 - when drawing on an image with an alpha channel where the source
463 minimum is greater than zero, Imager would read from beyond the end
464 of a malloc() allocated buffer. In rare circumstances this could
465 lead to some of the source image not being written to the target
466 image, or possibly to a segmentation fault.
467 I don't believe this has any security concerns beyond that.
468
0d052fd9
TC
469 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
470 text drawn would be nonsense. This would also read beyond the end
471 of a malloced buffer.
472

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

522 Mixed SampleFormat are handled incorrectly, since libtiff returns

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

789 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
790 the API level compiled into a loadable module such as
791 Imager::File::GIF doesn't match that of Imager. Previously it
792 could be difficult to determine exactly which module was failing to

TC
814 - when downconverting samples (eg. from floating point to 8 bit)
815 Imager now rounds the sample value rather than attempting to
816 allocate input values over output values equally. The old
817 behaviour had the probably surprising effect of converting a
818 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
819 2.
820 This may result in slightly different 8 or 16-bit output images.

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

847 handle a statically linked libpng.
848 https://rt.cpan.org/Ticket/Display.html?id=74043
849
850 - if a probe includes testcode, Imager::Probe now checks that code as
851 part of the process of checking each configuration rather than as a
852 post test of the found configuration. This allows alternate
853 configurations to be checked if a matching but non-working

903 - Imager (and the bundled dynamic modules) no longer fallback to
904 using DynaLoader if loading via XSLoader fails.
905 For the bundled modules this could hide useful error messages.
906 https://rt.cpan.org/Ticket/Display.html?id=75560
907

TC
908 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
909 buffer in the array of allocations, but just stores the filename
910 pointer and line number.

927 - note that the generator of the apparently non-DFSG-free postscript
928 in MMOne.pfb is a Debian package.
929
02323e69
TC
930 - setsamples() is now a true complement to getsamples() - it can
931 write 8-bit or floating point samples from a scalar or array
932 reference. This adds i_psamp() and i_psampf() to the C level API.
933
934 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
935 changed to make better use of the typemap, but these aren't part of
936 the perl level API anyway. There were no changes to the C level
937 interfaces to these functions.
938
2a27eeff
TC
939 - getpixel() and setpixel() now accept a mix of scalar and array
940 references for the x and y parameters, and unequal array lengths is
941 no longer an error.

963

990 based on the file header, to match read_multi().

TC
1092 - io_glue I/O buffering re-work:
1093
1094 - reorganize io_glue to do it's own buffering by default
1095
1096 - the unbuffered functions are available as i_io_raw_read() (or
1097 raw_read() from perl) etc but are not recommended for typical
1098 use.
1099
1100 - use the new i_io_peekn() when checking for file magic to avoid
1101 seek, allowing Imager to detect the file type and read the file
1102 from an unseekable stream (for formats that don't use random
1103 access)
1104
1105 - added several new I/O layer API functions.
1106
1107 - fix the TGA performance problem, most noticably on Win32
1108 https://rt.cpan.org/Ticket/Display.html?id=70037
1109
1110 - TIFF now uses wrapper functions of the correct types to avoid casts
1111 https://rt.cpan.org/Ticket/Display.html?id=69912
1112
1113 - the callback IO object did its own buffering, controlled by the
1114 maxbuffer parameter supplied to the read() and write() methods.
1115 This buffering has been removed, to avoid redundancy with the
1116 common io_glue buffering. This also avoids a bug in that code
1117 which could rarely pass a zero length to the read callback and
1118 then panic about the result.
1119
1120 - the callback IO object now tests the result of calling the close
1121 callback, which should return true for success.
1122
1123 - the PNM reader did its own buffering. This buffering has been
1124 removed to avoid redundancy with the common io_glue buffering.
1125
1126 - previously the read handlers for fd and callback I/O layers would
1127 call the underlying interface (POSIX read or your supplied callback)
1128 until it filled the buffer. It now only makes one call.
1129
1130 - added public constructors for I/O layer objects (see Imager::IO)
1131
1132 - all core file handlers now use the i_io_foo() wrappers to gain
1133 access to buffered I/O rather than calling the I/O layer
1134 callbacks directly.
1135
1136 - all core file handlers now check for error on close.
1137
1138 - Backward compatibility: if you hava custom file handlers, you can
1139 use i_io_write() etc since they're available as macros in older
1140 versions of Imager.
1141
1142 - eliminate the final remnants of io_glue_commit_types().
1143
1144 - bump IMAGER_API_VERSION, since the above may break assumptions.
1145
1146 - removed the long unused i_gen_reader() and i_gen_writer() utility
1147 functions.

1152The main changes in the release versus 0.84 are:

1154 - on 64-bit systems, 64-bit types are consistently used for image
1155 dimensions and co-ordinated, and for memory block sizes.
1156
1157 - handle IFD loops in TIFF files correctly. Previously this would
1158 lead to an infinite loop.

1210Development release as a sanity check for the types re-work.
8d14daab
TC
1211
1212Massive types re-work:
1213
1214 - the type used internally for pixel co-ordinates and image sizes is
1215 now 64-bit on 64-bit platforms (at least sane ones).
1216
1217 - size_t is now used consistently for memory block sizes.
1218
1219 - since this changes the binary interface, the Imager API version has
1220 been incremented. Any module that uses the API will need to be
1221 rebuilt. In most cases that will be enough, but calls to any APIs
1222 that take a pointer to image sizes may need source changes.
1223
1224 - you should be able to create very large images on 64-bit systems,
1225 if you have enough memory. Successfully created a 32768 x 49192 x
1226 3 channel image, filled with a tiled image and scaled it. The
1227 unscaled image was also successfully saved to a JPEG.
1228
1229 - check the image size before attempting to write BMP, GIF, JPEG,
1230 PNG, SGI, TGA, TIFF images.
1231
1232 - correctly handle reading TGA images over 32767 pixels wide or tall.
1233
1234Incidental changes:
1235
1236 - the gif_left and gif_top tags are now clamped to non-negative
1237 values when writing a GIF image.
1238
1239 - removed dead callback read/write code
1240
1241The default maximum memory size when reading files is now 1G.

1862 resulting in a SIGSEGV when attempting to scale an image to a size
1863 too large to fit in memory. This is a NULL pointer access issue,
1864 not a buffer overflow.

1879This release primarily contains changes to improve ease of use -
1880rather than you having to convert images to the appropriate number of
1881channels, Imager handles it internally. How to handle drawing colors
1882and the default combine mode is a thornier problem left for some other
1883release.

TC
1888 - moved the imtoc.perl code into Imager::Preprocess
1889
1890 - paste() and rubthrough() now adapt the source image data to the
1891 destination, so you can now safely paste/rubthrough from greyscale
1892 images to color images or back, or from alpha channel images to
1893 noalpha channels or back.
1894 https://rt.cpan.org/Ticket/Display.html?id=30908
1895
1896 - rubthrough() now falls back to pasting when the source doesn't have
1897 an alpha channel. This effectively treats the source as having a
1898 max alpha channel, the right thing to do.
1899 http://rt.cpan.org/Ticket/Display.html?id=29944
1900
1901 - re-worked most of the area filling code to use a common set of
1902 functions when filling.
1903 Corrected normal combine mode.
1904 Rewrote most of the combine modes to match the way the SVG draft
1905 defines them with respect to a translucent source and destination.
1906 Added tests for translucent source and destination.
1907 Added tests to check 8-bit/sample and double/sample combines work
1908 similarly.

1946
1947 - handling of the left-over bit for 16-bit/pixel TGA images has been
1948 changed to match the behaviour of the GIMP. Previously the bit
1949 being set was treated as an opaque pixel, but one user reported a
1950 problem with loading such an image. I haven't been able to find any
1951 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1952 I'll match it's behaviour. See issue 114913 in the GIMP's
1953 bugzilla.

1963 - the old dynaload code used Mach API functions to load dynamic
1964 libraries on Mac OS X. These APIs have been deprecated in OS X
1965 10.5 and were causing some build problems.

2199 - reworked library probing, we can now set more than one probe
2200 function for a library. Disabled the default (non-freetype-config)
2201 library probe and added an extra probe function that searches for
2202 both ft2build.h and whatever it includes, and adds -I as needed.
2203 Hopefully this will fix build problems like

2271Imager 0.55 - 16 Dec 2006
2272===========
2273
2274This is primarily a bug fix release.
2275
2276Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2277
2278There is one new feature:
2279
2280 - the Win32 font driver now supports UTF8 (RT 22166)
2281 http://www.cpanforum.com/threads/3276
2282 http://rt.cpan.org/Ticket/Display.html?id=22166
2283
2284Several bugs were fixed:
2285
2286 - the string() method would not output the string "0"
2287 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2288
2289 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2290 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2291
2292 - the gif_disposal and gif_user_input tags weren't being read from
2293 the file correctly
2294 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2295
2296 - gif.c was failing to build under MSVC
2297 http://rt.cpan.org/Ticket/Display.html?id=23922
2298
2299 - in some cases strings passed to the string() method were treated as
2300 terminated by NUL (chr 0)
2301 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2302
2303 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2304 that's the default build name for zlib on Win32.
2305 http://rt.cpan.org/Ticket/Display.html?id=23064
2306
2307 - search $Config{incpath} for headers too, which we should have been
2308 doing all along.
2309
2310Win32 font driver fixes:
2311
2312 - the global descent value from bounding box was the wrong sign
2313 http://www.cpanforum.com/threads/3276
2314
2315 - if the first or last glyph overflowed the left or right side of the
2316 advance width they would be clipped
2317
2318
2319Imager 0.54 - 14 Sep 2006
2320===========
2321
2322This is primarily a feature release:
2323
2324 - a new qtype value 'mixing' has been added to the scale()
2325 method. This is faster than 'normal', slower than 'preview'. This
2326 is based on the method used by pnmscale, and seems to produce less
2327 blurry results than normal.
2328 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2329
2330 - the rubthrough() method can now render onto images with an alpha
2331 channel.
2332 http://rt.cpan.org/Ticket/Display.html?id=20678
2333
2334 - the read_multi() method now falls back to calling doing a single
2335 image read via the read() method and write_multi() will now fall
2336 back to calling write() if a single image is supplied. This means
2337 you can simply call the read_multi() or write_multi() functions
2338 without having to check if the type is formatted by that method.
2339 http://rt.cpan.org/Ticket/Display.html?id=19457
2340 http://rt.cpan.org/Ticket/Display.html?id=19458
2341
2342 - the GIF loop extension can now be written. If you don't have
2343 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2344 should upgrade.
2345 http://rt.cpan.org/Ticket/Display.html?id=21185
2346
2347 - getscanline() and setscanline() can now read/write palette index
2348 based data from/to the image for paletted images, by setting type to
2349 'index'.
2350 http://rt.cpan.org/Ticket/Display.html?id=20338
2351
2352 - we no longer hassle you to disable GIF support
2353 http://rt.cpan.org/Ticket/Display.html?id=20687
2354
2355 - minor documentation fixes
2356
2357
2358Imager 0.53 - 26 Jul 2006
2359===========
2360
2361This is a bugfix release.
2362
2363Some test code was left in a code path not covered by the test
2364suite. A test was added to cover this code path and the test code was
2365removed.
2366http://rt.cpan.org/Public/Bug/Display.html?id=20705
2367
2368
2369Imager 0.52 - 25 Jul 2006
2370===========
2371
2372This is primarily a feature release, but contains a fair few bug
2373fixes, new features:
2374
2375 - ability to read and write MS Windows ICO and CUR files
2376
2377 - you can now add file format plugins to support new file formats
2378
2379 - add POD coverage tests
2380
2381 - setcolors() and addcolors() now accept color names and so on
2382 instead of requiring Imager::Color objects.
2383 http://rt.cpan.org/Ticket/Display.html?id=20056
2384
2385 - flood_fill() can now fill to a specified border color instead of
2386 just to the area the same color as the seed.
2387 http://rt.cpan.org/Ticket/Display.html?id=19618
2388
2389
2390Bug fixes:
2391
2392 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2393 calculating the advance width.
2394 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2395
2396 - bounding_box for the T1 driver wasn't including leading and
2397 trailing spaces in the bounding box as the other drivers did, it also
2398 produced strange results for empty strings or strings containing only
2399 spaces
2400
2401 - when reading CMYK jpeg images they were being transferred to the
2402 image object as is, producing a four channel image. It only looked ok
2403 due to an old still unfixed Photoshop bug. We now convert from the
2404 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2405 http://rt.cpan.org/Ticket/Display.html?id=20416
2406
2407 - reading a CYMK TIFF would result in a 4 channel image, reading any
2408 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2409 result in an error.
2410 http://rt.cpan.org/Ticket/Display.html?id=20415
2411
2412 - added /usr/local/include to the default include search path, since
2413 we were already searching /usr/local/lib for libraries.
2414
2415And various minor fixes and documentation updates.
2416
2417
2418Imager 0.51 - 23 Apr 2006

2422 a crash
2423 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2424
2425 - fix mis-processing of the src_maxx and src_maxy parameters of the
2426 paste() method
2427 http://rt.cpan.org/Public/Bug/Display.html?id=18712
2428
2429 - fix a problem in Imager's "smart" handling of the color parameter
2430 to various methods.
2431 http://rt.cpan.org/Public/Bug/Display.html?id=18561
2432
2433

2438 or 4 channel image to jpeg or a 2 channel image to tga where the
2439 output is an in-memeory buffer.
2440 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2441
2442 - fixes an incorrect pointer parameter in the PNG code
2443 http://rt.cpan.org/Public/Bug/Display.html?id=18051
2444
2445 - skip Inline::C tests when building in a directory with spaces
2446 http://rt.cpan.org/Public/Bug/Display.html?id=18049
