5497656d
TC
12============
13
14General changes:
15
16 - added the add_file_magic() class method for adding magic for new
17 file types to Imager's fairly primitive file magic detection.
18
19 - fixed an embarassing documentation typo in Imager::Test.
20
21 - trying to read from a GIF file with no images now sets an error
22 message. Thanks to Peter Sergeant for reporting this.

TC
25 - use undeprecated encoding symbols for FT2. This should fix the
26 build on the badly patched CentOS 7 Freetype 2. Thanks to Slaven
27 Rezic for the report.

30Coverity has come back up read-only, a few more changes:
31
32 - add missing va_end() for bmp.c's write_packed(). CID 185320.
33
34 - similarly for read_packed(). CID 185329.
35
36 - add a NOTREACHED lint comment for pixel_coverage(). Compilers
37 complained about a missing return, Coverity complains about the
38 return. CID 185325.
39
40 - avoid a possible sign extension in imsgi.c. CID 185326.
41
42 - add some FALLTHROUGH lint comments to i_readtga_wiol() where we
43 deliberately fall through switch cases. CID 185328.
44
45 - add assertions in callers to i_new_hatch_low() since Coverity
46 complained about some possible inconsistent NULL checks. CID
47 185339. I ended up rearranging this function later.
48
49 - remove pointless NULL checks from i_flipxy() and i_img_destroy().

53============
54
1456b645
TC
55Critical issue:
56
57 - drawing a filled, anti-aliased circle to the left or right of the
58 image (not within the image at all) would cause a buffer overflow.
59 https://rt.cpan.org/Ticket/Display.html?id=128208
60
a3b721bb
TC
61General changes:
62
63 - to_paletted() and make_palette() now fail (with an error in
64 errstr()) if invalid quantization parameters are supplied.
65
35ec3a87
TC
66 - map() would corrupt a channel if there was a gap in the arrayref of
67 channels. Detected by Coverity. CID 185300.
68
5824f4c2
TC
69 - most numeric parameters to the XS implementation now throw an
70 exception if supplied an unoverloaded reference.
71 https://rt.cpan.org/Ticket/Display.html?id=128208

TC
73Coverity finally finished a build[1], fixed several of the problems
74found. Coverity went down before I could finish working through them.
1791cbdb 75
8445279e
TC
76High severity:
77
1791cbdb 78 - reading a color-mapped TGA file with an id string would cause a
8445279e 79 double-free if the palette was truncated. CID 185317.
1791cbdb 80
6494c395
TC
81 - mixing scaling to sizes where the accumulator row, the working
82 output row or the working input row didn't fit into the address
83 space could result in memory leaks. This can probably only be
8445279e 84 reproduced on very wide floating-point sample images. CID 185318.
6494c395 85
fc24ca5f 86 - convert an array style function parameter pointer to pointer style
3d7b055c 87 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 88 CID 185343.
3d7b055c 89
8445279e 90 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 91
20c297d4 92 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 93 implementation. CID 185303.
20c297d4 94
fc24ca5f 95 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 96 drawing (it should always end up being set.) CID 185341.
fc24ca5f 97
f7675b46 98 - addi style makemap could potentially read one past the end of an
8445279e 99 array. CID 185337.
f7675b46 100
58ec1fde
TC
101 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
102 would result in read beyond the end of the built-in hatch array.
103 Negative values (which Coverity didn't complain about) could also
8445279e 104 cause problems. CID 185331.
58ec1fde 105
b7346865
TC
106 - the Imager::Color set_internal() interal method no longer
107 calls the over-complicated ICL_set_internal() (which is retained
108 only for the old API.) Coverity complained that this leaked, but
109 this could only occur with an invalid (NULL pointer) color object.
8445279e 110 CID 185323.
b7346865 111
785364c1
TC
112 - the underlying implementation of the map() method could read before
113 the beginning on an allocated array if supplied with inconsistent
114 parameters, which Coverity complained about. No Imager code calls
115 that function with inconsistent parameters, but a
8445279e 116 belt-and-suspenders check was added. CID 185315.
785364c1 117
eb7e48c9
TC
118 - Coverity complained a call to i_getcolors(), used by the
119 implementation of the is_bilevel() method could leave the fetched
8445279e 120 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 121
c1c8b1e9
TC
122 - a numeric combining mode of 13 (eg. as a parameter to
123 Imager::Fill->new())could cause an invalid array read in
124 i_get_combine() due to a fencepost error in validating the combine
8445279e 125 number. CID 185299.
c1c8b1e9 126
59fd0c6b 127Lower severity (according to Coverity):
c4fd43be
TC
128
129 - avoid an unneeded EXTEND() call when the FT1 has_chars()
130 implementation returns 0. CID 185350.
131
132 - avoid accessing a possibly NULL map from MakeMapObject() in a
133 logging call. (GIF) CID 185296.
134
4615ad8d
TC
135 - gradgen() allocated the wrong amount of space (always too much) for
136 the color array. CID 185291.
137
ea3099db
TC
138 - avoid dead code in i_tt_glyph_names(). CID 185321.
139
8b810590
TC
140 - avoid dead code in i_get_anonymous_color_histo(), which is the
141 implementation of getcolorusage(). CID 185327.
142
4eb9a521
TC
143 - avoid dead code in i_ft2_glyph_name(), which is the implementation
144 of glyph_names() for FT2. CID 185342.
145
c028aa12
TC
146 - avoid dead code in i_t1_glyph_names(), which is the implementation
147 of glyph_names() for T1. CID 185322.
148
e7772cea
TC
149 - avoid an unneeded EXTEND() call when the FT2 has_chars()
150 implementation returns 0. CID 185292.
151
596f3eee
TC
152 - the unpack code for ICO/CUR file handling could extend 32-bit
153 unsigned values to 64-bit signed. I believe this is harmless. CID
154 185319.
155
a2ca2b80
TC
156 - remove an unneeded check when terminating the stream for JPEG
157 writing. CID 185347.
158
56ce7446
TC
159 - skip an unneeded check when freeing the combine temp buffer in the
160 fountain filter. CID 185286.
161
162 - check the combine function pointer consistently rather than the
163 combine code in one place in the fountain filter.
164
a3b721bb
TC
165 - error diffusion now validates a custom error diffusion map and reports
166 an error if it's bad. CID 185288.
167
215d9ead
TC
168 - avoid discarding the value of i_io_getc() when scanning numbers in
169 pnm.c. CID 185293.
170
9ca939d0
TC
171 - handle failure to clone the log filehandle when cloning the Imager
172 context object on thread creation. CID 185294.
173
70501294 174 - fix an unsigned comparison when converting character code to a
59fd0c6b
TC
175 glyph index with a NULL character map when calculating the glyph
176 for display for FT1. This should be rare. CID 185297.
177
178 - fix a similar bug when calculating whether a glyph is present for
179 has_chars() for FT1. CID 185302.
70501294 180
6fa51f9c
TC
181 - i_img_info() (C API) no longer tries to handle a NULL image object
182 pointer. CID 185298.
183
a2c2d400
TC
184 - re-work testing for size_t overflow for circle/random
185 super-sampling for fountain fills. CID 185304.
186
8e2e2347
TC
187 - don't check if the unsigned size passed to Imager's malloc wrapper
188 (mymalloc) is negative. Left from when that parameter was signed.
189 CID 185305.
190
0c16f204
TC
191 - make some types larger and add a cast to prevent integer overflows
192 when calculating a palette with median cut for extraordinarily
193 large images. CID 185306.
194
748bfdfc
TC
195 - don't check if the unsigned size supplied to
196 im_set_image_file_limits() is negative. CID 185307.
197
57cc9afe 198[1] The first two build submissions ended up at the end of a ~400 item
a3b721bb
TC
199build queue, and seemed to have been cancelled by Coverity. A build
200submitted on NYE went through in minutes.

TC
202Imager 1.008 - 31 Dec 2018
203============
204
75e155e1 205 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
206 This allows file formats that store EXIF data as blobs similarly
207 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 208
b5bbf161 209 - added some more file extensions to image file type mappings
75e155e1
TC
210
211 - added add_type_extensions() class method
212
f38e738a
TC
213 - Imager::Files now links to Imager::Install when discussing
214 appropriate libraries.

219
a9fa5463
TC
220 - add png_compression_level tag for writing PNG files.
221
222 - avoid flooring a second time in matrix transform interpolation.

TC
231Imager 1.006 - 26 Aug 2017
232============
233
ba7ddbae
TC
234 - the internal i_errors() function now correctly allocates the stack
235 space needed for its result.
236 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
237
238 - t/100-base/020-color.t now uses Imager::Test's test functions
239 instead of its own.
240 https://rt.cpan.org/Ticket/Display.html?id=111993
241
344dda51
TC
242 - write_multi() now returns an error result (a false value) if called
243 with a non-(Imager image object). Previously it would typically
244 crash.
245 https://rt.cpan.org/Ticket/Display.html?id=117878
246
247 - improve the documentation of the jpegquality parameter when
248 writing JPEG files.
249
250 - add code to mitigate CVE-2016-1238, Imager will no longer search the
251 default current directory entry in @INC when searching for file
252 format support modules.

254Imager 1.005 - 16 Apr 2016
255============
256
257It's now been ten years since I switched to the new Changes file in
258release 0.55.
259
cd0109d8
TC
260 - revert the ivdformat probes, they don't work as is and trying to
261 fix them is too much work for now.
262
6f1cbfed
TC
263Imager 1.004_004 - 15 Apr 2016
264================
265
9c45cc49
TC
266 - test that the ivdformat from Config is correct and look for a valid
267 one if it isn't.
268 For the strange Win32 failures.
269
270 - fix a copy and paste error in pod in samples/samp-form.cgi
271

TC
272Imager 1.004_003 - 23 Mar 2016
273================
274
bd2d657d
TC
275 - add some extra error reporting to the I/O layers tests, this might
276 help catch a failure seen on Win32.

TC
279Imager 1.004_002 - 20 Mar 2016
280================
281
735b3e7b
TC
282 - don't use the seek() method on opened() handles in
283 t/200-file/400-basic.t. In older versions of perl such handles are
284 only IO::Handle objects, not IO::File, and don't have a seek()
285 method.

TC
287Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
288================
289
08914ed1
TC
290 - re-work the t/200-file/400-basic.t to correctly handle failures
291 It's custom ok() function didn't have a prototype and didn't use scalar().
292 This caused ok() to use the note instead of the value being tested when
293 the method called returned an empty list. For an example of the problem
e6226ce5 294 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 295
a2791e47
TC
296 - remove some noise from when Imager tried to work with bugs in old
297 versions of giflib. I can't do much about the new bugs.
08914ed1 298
e6226ce5
TC
299 - the new autolevels filter (Imager 0.99) used an integer for the
300 sample scaling factor which caused the top output level to be too
301 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
302 https://rt.cpan.org/Ticket/Display.html?id=111871
303
e6226ce5 304 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
305 minimum and maximum luminance from the histogram. This slightly
306 reduced the contrast of the output image.
307 https://rt.cpan.org/Ticket/Display.html?id=111871
308
309 - the new autolevels filter now uses a lookup table for 8-bit images
310 to avoid a floating point multiply for each sample.
311 https://rt.cpan.org/Ticket/Display.html?id=111871
312
e6226ce5
TC
313 - fixed several memory leaks detected by valgrind:
314
315 - addcolors() leaked the temporary array of colors supplied to the
316 internal API
317
318 - make_palette() leaked the temporary image array (not the images
319 themselves) passed to the internal API.
320
321 - combine()/i_combine() leaked its working row buffers
322
323 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
324 buffer if there were too many colors
325
326 - getcolorcount()/i_count_colors() leaked the sample buffer if
327 there were too many colors.
328
329 - the nearest_color filter (undocumented until I find a use for it)
330 leaked both temporaries passed to the API and internal buffers
331
a2791e47
TC
332 - the internal process of upgrading a paletted image to a direct
333 color image would leak a context object reference count.
334
335 - a write failure when writing to a GIF file could leak memory.
336
337 - failing to write to a 1-bit/pixel ICO image could leak memory.
338
339 - Imager no longer deliberately leaks the context object from the
340 initial thread. This was done to ensure there was always a context
341 object available, but the code that needed that now handles the
342 lack correctly,
343
e6226ce5
TC
344 - fixed some uninitialized memory usage detected by valgrind:
345
346 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
347 i_matrix_transform_bg() didn't initialize a working color value
348 if there was zero pixel coverage.
349
350 - i_ft2_cp() didn't initialize the complete color when producing an
351 intermediate image. This caused uninitialized value usage when
352 logging the color.

TC
354Imager 1.004 - 8 Nov 2015
355============
356
5ebfb369
TC
357 - Imager::Color::Table is now pre-loaded by the preload() method.
358 https://rt.cpan.org/Ticket/Display.html?id=104896
359
360 - fix an assertion triggered under perl 5.23.4.
361 Thanks to A. Sinan Unur for the report and the patch.
362
7b638aba
TC
363 - Imager->new can now be used to read raw image files.

f7160b21 365 Thanks to Richard Kelsch for reporting this.
7b638aba
TC
366
367 - deal with output changes from Pod::Spell

TC
370Imager 1.003 - 12 May 2015
371============
372
0fda3cfd
TC
373 - update 1.002 release notes to include the center change for filled
374 circle drawing.
375
376 - flood_fill() would escape beyond a 4-connected space under some
377 circumstances.
378 Added many more flood_fill() tests.

TC
381Imager 1.002 - 3 Apr 2015
382============
383
334b8922
TC
384 - drawing anti-aliased filled circles is now 10 to 50 times faster
385 depending on the size of the circle.
0fda3cfd
TC
386 This also changed the center from being the center of the pixel to
387 being the top left of the pixel to match the filled arcs drawn by
388 arc().
334b8922
TC
389 https://rt.cpan.org/Ticket/Display.html?id=101682
390
391 - enhancements to polygon filling:
392
393 - added a mode parameter to control how overlapping regions behave
394
395 - added a polypolygon() method to fill more than one polygon at a
396 time
397
398 - polygon filling is now exposed through the API.
399
45c8e262
TC
400 - added colormodel(), alphachannel() and colorchannels() methods.
401 These were added for two reasons:
402
403 - a future version of Imager may allow the number of channels in
404 an image to not directly represent the color model of an image.
405 eg. a greyscale TIFF image with multiple alpha channels.
406
407 - a future version of Imager may allow an image to be read without
408 translation, for example a TIFF file that contains measurements
0fda3cfd 409 from an instrument. Currently Imager transforms the samples into
d96c4de8 410 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
411 the value back.
412
413 An untranslated image would be unusable as image data, so
414 colormodel() would return "unknown" in this case.
415
416 Similarly a CMYK image might be returned as an "unknown" color
417 model image, if the caller chooses to disable translation to
418 RGB.

421============
422
aca60e01
TC
423 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
424 Thanks to Slaven Rezic for the report and the patch.

525 1.6.10 changed CRC errors from benign errors to normal errors,
526 which broke the test which used CRC errors to check for benign
527 error support. Switched to using a 1-bit grey-scale image with a
528 palette to test for benign errors.

532===========
533
f84f86a2
TC
534Incompatible changes:
535
536 - the return value of setpixel() has changed.
537
538 Previously the return values for undrawable pixels vs caller errors
539 changed depending on whether you used the multiple pixel calling
540 mechanism, or the single pixel mechanism.
541
542 Now:
543
544 - for an invalid parameter, such as an unknown colour, or missing
545 parameter, an empty list (or undef in scalar context) is
546 returned, and errstr() is set,
547
548 - otherwise the number of pixels drawn is returned. If none of
549 the pixels could be drawn (they were all outside the image), "0
550 but true" is returned.
551
552 https://rt.cpan.org/Ticket/Display.html?id=87650
553
554Other changes:
555
6ba09ab9
TC
556 - when drawing on an image with an alpha channel where the source
557 minimum is greater than zero, Imager would read from beyond the end
558 of a malloc() allocated buffer. In rare circumstances this could
559 lead to some of the source image not being written to the target
560 image, or possibly to a segmentation fault.
561 I don't believe this has any security concerns beyond that.
562
0d052fd9
TC
563 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
564 text drawn would be nonsense. This would also read beyond the end
565 of a malloced buffer.
566
13671b17

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

616 Mixed SampleFormat are handled incorrectly, since libtiff returns

884 the API level compiled into a loadable module such as

900===========
901
902Bug fixes:
903
904 - Imager::Test::is_imaged() attempted to process an "epsilon"
905 parameter but the prototype didn't allow for the extra parameter.
906 Corrected the prototype.

908 - when downconverting samples (eg. from floating point to 8 bit)
909 Imager now rounds the sample value rather than attempting to
910 allocate input values over output values equally. The old
911 behaviour had the probably surprising effect of converting a
912 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
913 2.
914 This may result in slightly different 8 or 16-bit output images.

916 - BI_BITFIELD BMP images were handled incorrectly, both in
917 incorrectly calculating the space required for the masks and in
918 processing the image data itself.

920
921 - some odd width BMP BI_RLE4 images use run lengths that run one off
922 the edge of the image. Imager now allows this, discarding the
923 extra column.

935 common for static linking, eg. libpng requires libz.
936 https://rt.cpan.org/Ticket/Display.html?id=74043
937
938 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.

941 handle a statically linked libpng.
942 https://rt.cpan.org/Ticket/Display.html?id=74043
943
944 - if a probe includes testcode, Imager::Probe now checks that code as
945 part of the process of checking each configuration rather than as a
946 post test of the found configuration. This allows alternate
947 configurations to be checked if a matching but non-working
948 configuration is found.

1186 - io_glue I/O buffering re-work:
1187
1188 - reorganize io_glue to do it's own buffering by default
1189
1190 - the unbuffered functions are available as i_io_raw_read() (or
1191 raw_read() from perl) etc but are not recommended for typical
1192 use.
1193
1194 - use the new i_io_peekn() when checking for file magic to avoid
1195 seek, allowing Imager to detect the file type and read the file
1196 from an unseekable stream (for formats that don't use random
1197 access)
1198
1199 - added several new I/O layer API functions.

1204 - TIFF now uses wrapper functions of the correct types to avoid casts
1205 https://rt.cpan.org/Ticket/Display.html?id=69912
1206
1207 - the callback IO object did its own buffering, controlled by the
1208 maxbuffer parameter supplied to the read() and write() methods.
1209 This buffering has been removed, to avoid redundancy with the
1210 common io_glue buffering. This also avoids a bug in that code
1211 which could rarely pass a zero length to the read callback and
1212 then panic about the result.
1213
1214 - the callback IO object now tests the result of calling the close
1215 callback, which should return true for success.
1216
1217 - the PNM reader did its own buffering. This buffering has been
1218 removed to avoid redundancy with the common io_glue buffering.
1219
1220 - previously the read handlers for fd and callback I/O layers would
1221 call the underlying interface (POSIX read or your supplied callback)
1222 until it filled the buffer. It now only makes one call.
1223
1224 - added public constructors for I/O layer objects (see Imager::IO)
1225
1226 - all core file handlers now use the i_io_foo() wrappers to gain
1227 access to buffered I/O rather than calling the I/O layer
1228 callbacks directly.
1229
1230 - all core file handlers now check for error on close.
1231
1232 - Backward compatibility: if you hava custom file handlers, you can
1233 use i_io_write() etc since they're available as macros in older
1234 versions of Imager.
1235
1236 - eliminate the final remnants of io_glue_commit_types().
1237
1238 - bump IMAGER_API_VERSION, since the above may break assumptions.
1239
1240 - removed the long unused i_gen_reader() and i_gen_writer() utility
1241 functions.

1304Development release as a sanity check for the types re-work.
8d14daab
TC
1305
1306Massive types re-work:
1307
1308 - the type used internally for pixel co-ordinates and image sizes is
1309 now 64-bit on 64-bit platforms (at least sane ones).
1310
1311 - size_t is now used consistently for memory block sizes.
1312
1313 - since this changes the binary interface, the Imager API version has
1314 been incremented. Any module that uses the API will need to be
1315 rebuilt. In most cases that will be enough, but calls to any APIs
1316 that take a pointer to image sizes may need source changes.
1317
1318 - you should be able to create very large images on 64-bit systems,
1319 if you have enough memory. Successfully created a 32768 x 49192 x
1320 3 channel image, filled with a tiled image and scaled it. The
1321 unscaled image was also successfully saved to a JPEG.
1322
1323 - check the image size before attempting to write BMP, GIF, JPEG,

1987 noalpha channels or back.
1988 https://rt.cpan.org/Ticket/Display.html?id=30908
1989
1990 - rubthrough() now falls back to pasting when the source doesn't have
1991 an alpha channel. This effectively treats the source as having a
1992 max alpha channel, the right thing to do.
1993 http://rt.cpan.org/Ticket/Display.html?id=29944

1999 defines them with respect to a translucent source and destination.

2044 problem with loading such an image. I haven't been able to find any
2045 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
2046 I'll match it's behaviour. See issue 114913 in the GIMP's

2204 - the mask for ICO/CUR images is now applied as an alpha channel to
2205 the returned image. For the old behaviour, supply ico_masked => 0

2207 using Imager as a general image processor.

2365Imager 0.55 - 16 Dec 2006
2366===========
2367
2368This is primarily a bug fix release.
2369
2370Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2371
2372There is one new feature:
2373
2374 - the Win32 font driver now supports UTF8 (RT 22166)
2375 http://www.cpanforum.com/threads/3276
2376 http://rt.cpan.org/Ticket/Display.html?id=22166
2377
2378Several bugs were fixed:
2379
2380 - the string() method would not output the string "0"
2381 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2382
2383 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2384 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2385
2386 - the gif_disposal and gif_user_input tags weren't being read from
2387 the file correctly
2388 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2389
2390 - gif.c was failing to build under MSVC
2391 http://rt.cpan.org/Ticket/Display.html?id=23922
2392
2393 - in some cases strings passed to the string() method were treated as
2394 terminated by NUL (chr 0)
2395 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2396
2397 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2398 that's the default build name for zlib on Win32.
2399 http://rt.cpan.org/Ticket/Display.html?id=23064
2400
2401 - search $Config{incpath} for headers too, which we should have been
2402 doing all along.
2403
2404Win32 font driver fixes:
2405
2406 - the global descent value from bounding box was the wrong sign
2407 http://www.cpanforum.com/threads/3276
2408
2409 - if the first or last glyph overflowed the left or right side of the
2410 advance width they would be clipped
2411
2412
2413Imager 0.54 - 14 Sep 2006
2414===========
2415
2416This is primarily a feature release:
2417
2418 - a new qtype value 'mixing' has been added to the scale()
2419 method. This is faster than 'normal', slower than 'preview'. This
2420 is based on the method used by pnmscale, and seems to produce less
2421 blurry results than normal.
2422 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2423
2424 - the rubthrough() method can now render onto images with an alpha
2425 channel.
2426 http://rt.cpan.org/Ticket/Display.html?id=20678
2427
2428 - the read_multi() method now falls back to calling doing a single
2429 image read via the read() method and write_multi() will now fall
2430 back to calling write() if a single image is supplied. This means
2431 you can simply call the read_multi() or write_multi() functions
2432 without having to check if the type is formatted by that method.
2433 http://rt.cpan.org/Ticket/Display.html?id=19457
2434 http://rt.cpan.org/Ticket/Display.html?id=19458
2435
2436 - the GIF loop extension can now be written. If you don't have
2437 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2438 should upgrade.
2439 http://rt.cpan.org/Ticket/Display.html?id=21185
2440
2441 - getscanline() and setscanline() can now read/write palette index
2442 based data from/to the image for paletted images, by setting type to
2443 'index'.
2444 http://rt.cpan.org/Ticket/Display.html?id=20338
2445
2446 - we no longer hassle you to disable GIF support
2447 http://rt.cpan.org/Ticket/Display.html?id=20687
2448
2449 - minor documentation fixes
2450
2451
2452Imager 0.53 - 26 Jul 2006
2453===========
2454
2455This is a bugfix release.
2456
2457Some test code was left in a code path not covered by the test
2458suite. A test was added to cover this code path and the test code was
2459removed.
2460http://rt.cpan.org/Public/Bug/Display.html?id=20705
2461
2462
2463Imager 0.52 - 25 Jul 2006
2464===========
2465
2466This is primarily a feature release, but contains a fair few bug
2467fixes, new features:
2468
2469 - ability to read and write MS Windows ICO and CUR files
2470
2471 - you can now add file format plugins to support new file formats
2472
2473 - add POD coverage tests
2474
2475 - setcolors() and addcolors() now accept color names and so on
2476 instead of requiring Imager::Color objects.
2477 http://rt.cpan.org/Ticket/Display.html?id=20056
2478
2479 - flood_fill() can now fill to a specified border color instead of
2480 just to the area the same color as the seed.
2481 http://rt.cpan.org/Ticket/Display.html?id=19618
2482
2483
2484Bug fixes:
2485
2486 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2487 calculating the advance width.
2488 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2489
2490 - bounding_box for the T1 driver wasn't including leading and
2491 trailing spaces in the bounding box as the other drivers did, it also
2492 produced strange results for empty strings or strings containing only
2493 spaces
2494
2495 - when reading CMYK jpeg images they were being transferred to the
2496 image object as is, producing a four channel image. It only looked ok
2497 due to an old still unfixed Photoshop bug. We now convert from the
2498 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2499 http://rt.cpan.org/Ticket/Display.html?id=20416
2500
2501 - reading a CYMK TIFF would result in a 4 channel image, reading any
2502 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2503 result in an error.
2504 http://rt.cpan.org/Ticket/Display.html?id=20415
2505
2506 - added /usr/local/include to the default include search path, since
2507 we were already searching /usr/local/lib for libraries.
2508
2509And various minor fixes and documentation updates.
2510
2511
2512Imager 0.51 - 23 Apr 2006
2513===========
2514

2516 a crash

2518
2519 - fix mis-processing of the src_maxx and src_maxy parameters of the

2533 output is an in-memeory buffer.
