a3b721bb
TC
3General changes:
4
5 - to_paletted() and make_palette() now fail (with an error in
6 errstr()) if invalid quantization parameters are supplied.
7
35ec3a87
TC
8 - map() would corrupt a channel if there was a gap in the arrayref of
9 channels. Detected by Coverity. CID 185300.
10
a3b721bb 11Coverity finally finished a build[1], fix a few problems:
1791cbdb 12
8445279e
TC
13High severity:
14
1791cbdb 15 - reading a color-mapped TGA file with an id string would cause a
8445279e 16 double-free if the palette was truncated. CID 185317.
1791cbdb 17
6494c395
TC
18 - mixing scaling to sizes where the accumulator row, the working
19 output row or the working input row didn't fit into the address
20 space could result in memory leaks. This can probably only be
8445279e 21 reproduced on very wide floating-point sample images. CID 185318.
6494c395 22
fc24ca5f 23 - convert an array style function parameter pointer to pointer style
3d7b055c 24 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 25 CID 185343.
3d7b055c 26
8445279e 27 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 28
20c297d4 29 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 30 implementation. CID 185303.
20c297d4 31
fc24ca5f 32 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 33 drawing (it should always end up being set.) CID 185341.
fc24ca5f 34
f7675b46 35 - addi style makemap could potentially read one past the end of an
8445279e 36 array. CID 185337.
f7675b46 37
58ec1fde
TC
38 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
39 would result in read beyond the end of the built-in hatch array.
40 Negative values (which Coverity didn't complain about) could also
8445279e 41 cause problems. CID 185331.
58ec1fde 42
b7346865
TC
43 - the Imager::Color set_internal() interal method no longer
44 calls the over-complicated ICL_set_internal() (which is retained
45 only for the old API.) Coverity complained that this leaked, but
46 this could only occur with an invalid (NULL pointer) color object.
8445279e 47 CID 185323.
b7346865 48
785364c1
TC
49 - the underlying implementation of the map() method could read before
50 the beginning on an allocated array if supplied with inconsistent
51 parameters, which Coverity complained about. No Imager code calls
52 that function with inconsistent parameters, but a
8445279e 53 belt-and-suspenders check was added. CID 185315.
785364c1 54
eb7e48c9
TC
55 - Coverity complained a call to i_getcolors(), used by the
56 implementation of the is_bilevel() method could leave the fetched
8445279e 57 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 58
c1c8b1e9
TC
59 - a numeric combining mode of 13 (eg. as a parameter to
60 Imager::Fill->new())could cause an invalid array read in
61 i_get_combine() due to a fencepost error in validating the combine
8445279e 62 number. CID 185299.
c1c8b1e9 63
59fd0c6b 64Lower severity (according to Coverity):
c4fd43be
TC
65
66 - avoid an unneeded EXTEND() call when the FT1 has_chars()
67 implementation returns 0. CID 185350.
68
69 - avoid accessing a possibly NULL map from MakeMapObject() in a
70 logging call. (GIF) CID 185296.
71
4615ad8d
TC
72 - gradgen() allocated the wrong amount of space (always too much) for
73 the color array. CID 185291.
74
ea3099db
TC
75 - avoid dead code in i_tt_glyph_names(). CID 185321.
76
8b810590
TC
77 - avoid dead code in i_get_anonymous_color_histo(), which is the
78 implementation of getcolorusage(). CID 185327.
79
4eb9a521
TC
80 - avoid dead code in i_ft2_glyph_name(), which is the implementation
81 of glyph_names() for FT2. CID 185342.
82
c028aa12
TC
83 - avoid dead code in i_t1_glyph_names(), which is the implementation
84 of glyph_names() for T1. CID 185322.
85
e7772cea
TC
86 - avoid an unneeded EXTEND() call when the FT2 has_chars()
87 implementation returns 0. CID 185292.
88
596f3eee
TC
89 - the unpack code for ICO/CUR file handling could extend 32-bit
90 unsigned values to 64-bit signed. I believe this is harmless. CID
91 185319.
92
a2ca2b80
TC
93 - remove an unneeded check when terminating the stream for JPEG
94 writing. CID 185347.
95
56ce7446
TC
96 - skip an unneeded check when freeing the combine temp buffer in the
97 fountain filter. CID 185286.
98
99 - check the combine function pointer consistently rather than the
100 combine code in one place in the fountain filter.
101
a3b721bb
TC
102 - error diffusion now validates a custom error diffusion map and reports
103 an error if it's bad. CID 185288.
104
215d9ead
TC
105 - avoid discarding the value of i_io_getc() when scanning numbers in
106 pnm.c. CID 185293.
107
9ca939d0
TC
108 - handle failure to clone the log filehandle when cloning the Imager
109 context object on thread creation. CID 185294.
110
70501294 111 - fix an unsigned comparison when converting character code to a
59fd0c6b
TC
112 glyph index with a NULL character map when calculating the glyph
113 for display for FT1. This should be rare. CID 185297.
114
115 - fix a similar bug when calculating whether a glyph is present for
116 has_chars() for FT1. CID 185302.
70501294 117
6fa51f9c
TC
118 - i_img_info() (C API) no longer tries to handle a NULL image object
119 pointer. CID 185298.
120
a2c2d400
TC
121 - re-work testing for size_t overflow for circle/random
122 super-sampling for fountain fills. CID 185304.
123
8e2e2347
TC
124 - don't check if the unsigned size passed to Imager's malloc wrapper
125 (mymalloc) is negative. Left from when that parameter was signed.
126 CID 185305.
127

TC
128[1] The first two build submissions ended up at the end of a ~400
129build queue, and seemed to have been cancelled by Coverity. A build
130submitted on NYE went through in minutes.

TC
132Imager 1.008 - 31 Dec 2018
133============
134
75e155e1 135 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
136 This allows file formats that store EXIF data as blobs similarly
137 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 138
b5bbf161 139 - added some more file extensions to image file type mappings
75e155e1
TC
140
141 - added add_type_extensions() class method

TC
157Imager 1.006 - 26 Aug 2017
158============
159
ba7ddbae
TC
160 - the internal i_errors() function now correctly allocates the stack
161 space needed for its result.
162 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
163
164 - t/100-base/020-color.t now uses Imager::Test's test functions
165 instead of its own.
166 https://rt.cpan.org/Ticket/Display.html?id=111993
167
344dda51
TC
168 - write_multi() now returns an error result (a false value) if called
169 with a non-(Imager image object). Previously it would typically
170 crash.
171 https://rt.cpan.org/Ticket/Display.html?id=117878
172
173 - improve the documentation of the jpegquality parameter when
174 writing JPEG files.
175
176 - add code to mitigate CVE-2016-1238, Imager will no longer search the
177 default current directory entry in @INC when searching for file
178 format support modules.

183It's now been ten years since I switched to the new Changes file in
184release 0.55.
185
cd0109d8
TC
186 - revert the ivdformat probes, they don't work as is and trying to
187 fix them is too much work for now.
188

TC
189Imager 1.004_004 - 15 Apr 2016
190================
191
9c45cc49
TC
192 - test that the ivdformat from Config is correct and look for a valid
193 one if it isn't.
194 For the strange Win32 failures.
195
196 - fix a copy and paste error in pod in samples/samp-form.cgi
197

TC
198Imager 1.004_003 - 23 Mar 2016
199================
200
bd2d657d
TC
201 - add some extra error reporting to the I/O layers tests, this might
202 help catch a failure seen on Win32.

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

213Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
214================
215
08914ed1
TC
216 - re-work the t/200-file/400-basic.t to correctly handle failures
217 It's custom ok() function didn't have a prototype and didn't use scalar().
218 This caused ok() to use the note instead of the value being tested when
219 the method called returned an empty list. For an example of the problem
e6226ce5 220 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 221
a2791e47
TC
222 - remove some noise from when Imager tried to work with bugs in old
223 versions of giflib. I can't do much about the new bugs.
08914ed1 224
e6226ce5
TC
225 - the new autolevels filter (Imager 0.99) used an integer for the
226 sample scaling factor which caused the top output level to be too
227 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
228 https://rt.cpan.org/Ticket/Display.html?id=111871
229
e6226ce5 230 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
231 minimum and maximum luminance from the histogram. This slightly
232 reduced the contrast of the output image.
233 https://rt.cpan.org/Ticket/Display.html?id=111871
234
235 - the new autolevels filter now uses a lookup table for 8-bit images
236 to avoid a floating point multiply for each sample.
237 https://rt.cpan.org/Ticket/Display.html?id=111871
238
e6226ce5
TC
239 - fixed several memory leaks detected by valgrind:
240
241 - addcolors() leaked the temporary array of colors supplied to the
242 internal API
243
244 - make_palette() leaked the temporary image array (not the images
245 themselves) passed to the internal API.
246
247 - combine()/i_combine() leaked its working row buffers
248
249 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
250 buffer if there were too many colors
251
252 - getcolorcount()/i_count_colors() leaked the sample buffer if
253 there were too many colors.
254
255 - the nearest_color filter (undocumented until I find a use for it)
256 leaked both temporaries passed to the API and internal buffers
257
a2791e47
TC
258 - the internal process of upgrading a paletted image to a direct
259 color image would leak a context object reference count.
260
261 - a write failure when writing to a GIF file could leak memory.
262
263 - failing to write to a 1-bit/pixel ICO image could leak memory.
264
265 - Imager no longer deliberately leaks the context object from the
266 initial thread. This was done to ensure there was always a context
267 object available, but the code that needed that now handles the
268 lack correctly,
269
e6226ce5
TC
270 - fixed some uninitialized memory usage detected by valgrind:
271
272 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
273 i_matrix_transform_bg() didn't initialize a working color value
274 if there was zero pixel coverage.
275
276 - i_ft2_cp() didn't initialize the complete color when producing an
277 intermediate image. This caused uninitialized value usage when
278 logging the color.

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

296Imager 1.003 - 12 May 2015
297============
298
0fda3cfd
TC
299 - update 1.002 release notes to include the center change for filled
300 circle drawing.
301
302 - flood_fill() would escape beyond a 4-connected space under some
303 circumstances.
304 Added many more flood_fill() tests.

TC
307Imager 1.002 - 3 Apr 2015
308============
309
334b8922
TC
310 - drawing anti-aliased filled circles is now 10 to 50 times faster
311 depending on the size of the circle.
0fda3cfd
TC
312 This also changed the center from being the center of the pixel to
313 being the top left of the pixel to match the filled arcs drawn by
314 arc().
334b8922
TC
315 https://rt.cpan.org/Ticket/Display.html?id=101682
316
317 - enhancements to polygon filling:
318
319 - added a mode parameter to control how overlapping regions behave
320
321 - added a polypolygon() method to fill more than one polygon at a
322 time
323
324 - polygon filling is now exposed through the API.
325
45c8e262
TC
326 - added colormodel(), alphachannel() and colorchannels() methods.
327 These were added for two reasons:
328
329 - a future version of Imager may allow the number of channels in
330 an image to not directly represent the color model of an image.
331 eg. a greyscale TIFF image with multiple alpha channels.
332
333 - a future version of Imager may allow an image to be read without
334 translation, for example a TIFF file that contains measurements
0fda3cfd 335 from an instrument. Currently Imager transforms the samples into
d96c4de8 336 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
337 the value back.
338
339 An untranslated image would be unusable as image data, so
340 colormodel() would return "unknown" in this case.
341
342 Similarly a CMYK image might be returned as an "unknown" color
343 model image, if the caller chooses to disable translation to
344 RGB.

385==============
386
5dab5b9a
TC
387 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
388 the blue channel in the generated palette, and allow each color
389 component to be in the range 100..255 instead of just 100..254.
390 Thanks to Ralf Neubauer.
391 https://rt.cpan.org/Ticket/Display.html?id=97086
392
393 - revert "improved the XS for i_io_read() and i_io_raw_read()"
394 This caused problems with older perls and didn't provide much of a
395 performance improvement.
396
5bf25bc2 397 - support Inline 0.57 and later.

dce1523b
TC
424 - Imager::IO->new_buffer() (and hence Imager->read()'s data
425 parameter) now accepts a reference to a scalar as well as just a
426 plain scalar.

451 1.6.10 changed CRC errors from benign errors to normal errors,
452 which broke the test which used CRC errors to check for benign
453 error support. Switched to using a 1-bit grey-scale image with a

460Incompatible changes:
461
462 - the return value of setpixel() has changed.
463
464 Previously the return values for undrawable pixels vs caller errors
465 changed depending on whether you used the multiple pixel calling
466 mechanism, or the single pixel mechanism.
467
468 Now:
469
470 - for an invalid parameter, such as an unknown colour, or missing
471 parameter, an empty list (or undef in scalar context) is
472 returned, and errstr() is set,
473
474 - otherwise the number of pixels drawn is returned. If none of
475 the pixels could be drawn (they were all outside the image), "0
476 but true" is returned.

TC
482 - when drawing on an image with an alpha channel where the source
483 minimum is greater than zero, Imager would read from beyond the end
484 of a malloc() allocated buffer. In rare circumstances this could
485 lead to some of the source image not being written to the target
486 image, or possibly to a segmentation fault.
487 I don't believe this has any security concerns beyond that.
488
0d052fd9
TC
489 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
490 text drawn would be nonsense. This would also read beyond the end
491 of a malloced buffer.

542 Mixed SampleFormat are handled incorrectly, since libtiff returns

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

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

TC
834 - when downconverting samples (eg. from floating point to 8 bit)
835 Imager now rounds the sample value rather than attempting to
836 allocate input values over output values equally. The old
837 behaviour had the probably surprising effect of converting a
838 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
839 2.
840 This may result in slightly different 8 or 16-bit output images.

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

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

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

1112 - io_glue I/O buffering re-work:
1113
1114 - reorganize io_glue to do it's own buffering by default
1115
1116 - the unbuffered functions are available as i_io_raw_read() (or
1117 raw_read() from perl) etc but are not recommended for typical
1118 use.
1119
1120 - use the new i_io_peekn() when checking for file magic to avoid
1121 seek, allowing Imager to detect the file type and read the file
1122 from an unseekable stream (for formats that don't use random
1123 access)
1124
1125 - added several new I/O layer API functions.
1126
1127 - fix the TGA performance problem, most noticably on Win32
1128 https://rt.cpan.org/Ticket/Display.html?id=70037
1129
1130 - TIFF now uses wrapper functions of the correct types to avoid casts
1131 https://rt.cpan.org/Ticket/Display.html?id=69912
1132
1133 - the callback IO object did its own buffering, controlled by the
1134 maxbuffer parameter supplied to the read() and write() methods.
1135 This buffering has been removed, to avoid redundancy with the
1136 common io_glue buffering. This also avoids a bug in that code
1137 which could rarely pass a zero length to the read callback and
1138 then panic about the result.
1139
1140 - the callback IO object now tests the result of calling the close
1141 callback, which should return true for success.
1142
1143 - the PNM reader did its own buffering. This buffering has been
1144 removed to avoid redundancy with the common io_glue buffering.
1145
1146 - previously the read handlers for fd and callback I/O layers would
1147 call the underlying interface (POSIX read or your supplied callback)
1148 until it filled the buffer. It now only makes one call.
1149
1150 - added public constructors for I/O layer objects (see Imager::IO)
1151
1152 - all core file handlers now use the i_io_foo() wrappers to gain
1153 access to buffered I/O rather than calling the I/O layer
1154 callbacks directly.
1155
1156 - all core file handlers now check for error on close.
1157
1158 - Backward compatibility: if you hava custom file handlers, you can
1159 use i_io_write() etc since they're available as macros in older
1160 versions of Imager.
1161
1162 - eliminate the final remnants of io_glue_commit_types().
1163
1164 - bump IMAGER_API_VERSION, since the above may break assumptions.
1165
1166 - removed the long unused i_gen_reader() and i_gen_writer() utility
1167 functions.

1230Development release as a sanity check for the types re-work.
8d14daab
TC
1231
1232Massive types re-work:
1233
1234 - the type used internally for pixel co-ordinates and image sizes is
1235 now 64-bit on 64-bit platforms (at least sane ones).
1236
1237 - size_t is now used consistently for memory block sizes.
1238
1239 - since this changes the binary interface, the Imager API version has
1240 been incremented. Any module that uses the API will need to be
1241 rebuilt. In most cases that will be enough, but calls to any APIs
1242 that take a pointer to image sizes may need source changes.
1243
1244 - you should be able to create very large images on 64-bit systems,
1245 if you have enough memory. Successfully created a 32768 x 49192 x
1246 3 channel image, filled with a tiled image and scaled it. The
1247 unscaled image was also successfully saved to a JPEG.
1248
1249 - check the image size before attempting to write BMP, GIF, JPEG,
1250 PNG, SGI, TGA, TIFF images.
1251
1252 - correctly handle reading TGA images over 32767 pixels wide or tall.
1253
1254Incidental changes:
1255
1256 - the gif_left and gif_top tags are now clamped to non-negative
1257 values when writing a GIF image.
1258
1259 - removed dead callback read/write code
1260
1261The default maximum memory size when reading files is now 1G.

1871 - Possible security issue: The floating point sample path for image

1877 - check that the result of fileno($fh) is defined rather than simply
1878 true when read() or write() is supplied with an fh parameter.
1879 http://rt.cpan.org/Ticket/Display.html?id=35139
1880
1881 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1882 resulting in a SIGSEGV when attempting to scale an image to a size
1883 too large to fit in memory. This is a NULL pointer access issue,
1884 not a buffer overflow.
1885 Added a check for the failure.
1886 scale_calculate() (and hence scale()) will now fail if any of the

1899This release primarily contains changes to improve ease of use -
1900rather than you having to convert images to the appropriate number of
1901channels, Imager handles it internally. How to handle drawing colors
1902and the default combine mode is a thornier problem left for some other
1903release.

TC
1908 - moved the imtoc.perl code into Imager::Preprocess
1909
1910 - paste() and rubthrough() now adapt the source image data to the
1911 destination, so you can now safely paste/rubthrough from greyscale
1912 images to color images or back, or from alpha channel images to
1913 noalpha channels or back.
1914 https://rt.cpan.org/Ticket/Display.html?id=30908
1915
1916 - rubthrough() now falls back to pasting when the source doesn't have
1917 an alpha channel. This effectively treats the source as having a
1918 max alpha channel, the right thing to do.
1919 http://rt.cpan.org/Ticket/Display.html?id=29944
1920
1921 - re-worked most of the area filling code to use a common set of
1922 functions when filling.
1923 Corrected normal combine mode.
1924 Rewrote most of the combine modes to match the way the SVG draft
1925 defines them with respect to a translucent source and destination.
1926 Added tests for translucent source and destination.
1927 Added tests to check 8-bit/sample and double/sample combines work
1928 similarly.

1964 - some TGA images weren't being detected correctly as TGA images
1965 https://rt.cpan.org/Ticket/Display.html?id=32925
1966
1967 - handling of the left-over bit for 16-bit/pixel TGA images has been
1968 changed to match the behaviour of the GIMP. Previously the bit
1969 being set was treated as an opaque pixel, but one user reported a
1970 problem with loading such an image. I haven't been able to find any
1971 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1972 I'll match it's behaviour. See issue 114913 in the GIMP's
1973 bugzilla.

1983 - the old dynaload code used Mach API functions to load dynamic
1984 libraries on Mac OS X. These APIs have been deprecated in OS X
1985 10.5 and were causing some build problems.
1986 So henceforth Imager uses the dlopen() family of functions, and you
1987 will need version 10.3 or later of OS X.

2291Imager 0.55 - 16 Dec 2006
2292===========
2293
2294This is primarily a bug fix release.
2295
2296Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2297
2298There is one new feature:
2299
2300 - the Win32 font driver now supports UTF8 (RT 22166)
2301 http://www.cpanforum.com/threads/3276
2302 http://rt.cpan.org/Ticket/Display.html?id=22166
2303
2304Several bugs were fixed:
2305
2306 - the string() method would not output the string "0"
2307 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2308
2309 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2310 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2311
2312 - the gif_disposal and gif_user_input tags weren't being read from
2313 the file correctly
2314 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2315
2316 - gif.c was failing to build under MSVC
2317 http://rt.cpan.org/Ticket/Display.html?id=23922
2318
2319 - in some cases strings passed to the string() method were treated as
2320 terminated by NUL (chr 0)
2321 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2322
2323 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2324 that's the default build name for zlib on Win32.
2325 http://rt.cpan.org/Ticket/Display.html?id=23064
2326
2327 - search $Config{incpath} for headers too, which we should have been
2328 doing all along.
2329
2330Win32 font driver fixes:
2331
2332 - the global descent value from bounding box was the wrong sign
2333 http://www.cpanforum.com/threads/3276
2334
2335 - if the first or last glyph overflowed the left or right side of the
2336 advance width they would be clipped
2337
2338
2339Imager 0.54 - 14 Sep 2006
2340===========
2341
2342This is primarily a feature release:
2343
2344 - a new qtype value 'mixing' has been added to the scale()
2345 method. This is faster than 'normal', slower than 'preview'. This
2346 is based on the method used by pnmscale, and seems to produce less
2347 blurry results than normal.
2348 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2349
2350 - the rubthrough() method can now render onto images with an alpha
2351 channel.
2352 http://rt.cpan.org/Ticket/Display.html?id=20678
2353
2354 - the read_multi() method now falls back to calling doing a single
2355 image read via the read() method and write_multi() will now fall
2356 back to calling write() if a single image is supplied. This means
2357 you can simply call the read_multi() or write_multi() functions
2358 without having to check if the type is formatted by that method.
2359 http://rt.cpan.org/Ticket/Display.html?id=19457
2360 http://rt.cpan.org/Ticket/Display.html?id=19458
2361
2362 - the GIF loop extension can now be written. If you don't have
2363 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2364 should upgrade.
2365 http://rt.cpan.org/Ticket/Display.html?id=21185
2366
2367 - getscanline() and setscanline() can now read/write palette index
2368 based data from/to the image for paletted images, by setting type to
2369 'index'.
2370 http://rt.cpan.org/Ticket/Display.html?id=20338
2371
2372 - we no longer hassle you to disable GIF support
2373 http://rt.cpan.org/Ticket/Display.html?id=20687
2374
2375 - minor documentation fixes
2376
2377
2378Imager 0.53 - 26 Jul 2006
2379===========
2380
2381This is a bugfix release.
2382
2383Some test code was left in a code path not covered by the test
2384suite. A test was added to cover this code path and the test code was
2385removed.
2386http://rt.cpan.org/Public/Bug/Display.html?id=20705
2387
2388
2389Imager 0.52 - 25 Jul 2006
2390===========
2391
2392This is primarily a feature release, but contains a fair few bug
2393fixes, new features:
2394
2395 - ability to read and write MS Windows ICO and CUR files
2396
2397 - you can now add file format plugins to support new file formats
2398
2399 - add POD coverage tests
2400
2401 - setcolors() and addcolors() now accept color names and so on
2402 instead of requiring Imager::Color objects.
2403 http://rt.cpan.org/Ticket/Display.html?id=20056
2404
2405 - flood_fill() can now fill to a specified border color instead of
2406 just to the area the same color as the seed.
2407 http://rt.cpan.org/Ticket/Display.html?id=19618
2408
2409
2410Bug fixes:
2411
2412 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2413 calculating the advance width.
2414 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2415
2416 - bounding_box for the T1 driver wasn't including leading and
2417 trailing spaces in the bounding box as the other drivers did, it also
2418 produced strange results for empty strings or strings containing only
2419 spaces
2420
2421 - when reading CMYK jpeg images they were being transferred to the
2422 image object as is, producing a four channel image. It only looked ok
2423 due to an old still unfixed Photoshop bug. We now convert from the
2424 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2425 http://rt.cpan.org/Ticket/Display.html?id=20416
2426
2427 - reading a CYMK TIFF would result in a 4 channel image, reading any
2428 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2429 result in an error.
2430 http://rt.cpan.org/Ticket/Display.html?id=20415
2431
2432 - added /usr/local/include to the default include search path, since
2433 we were already searching /usr/local/lib for libraries.
2434
2435And various minor fixes and documentation updates.
2436
2437
2438Imager 0.51 - 23 Apr 2006

2442 a crash
2443 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2444
2445 - fix mis-processing of the src_maxx and src_maxy parameters of the

2459 output is an in-memeory buffer.
