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
70501294
TC
108 - fix an unsigned comparison when converting character code to a
109 glyph index with a NULL character map. This should be rare. CID
110 185297.
111
a3b721bb
TC
112[1] The first two build submissions ended up at the end of a ~400
113build queue, and seemed to have been cancelled by Coverity. A build
114submitted on NYE went through in minutes.

116Imager 1.008 - 31 Dec 2018
117============
118
75e155e1 119 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
120 This allows file formats that store EXIF data as blobs similarly
121 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 122
b5bbf161 123 - added some more file extensions to image file type mappings
75e155e1
TC
124
125 - added add_type_extensions() class method

TC
141Imager 1.006 - 26 Aug 2017
142============
143
ba7ddbae
TC
144 - the internal i_errors() function now correctly allocates the stack
145 space needed for its result.
146 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
147
148 - t/100-base/020-color.t now uses Imager::Test's test functions
149 instead of its own.
150 https://rt.cpan.org/Ticket/Display.html?id=111993
151
344dda51
TC
152 - write_multi() now returns an error result (a false value) if called
153 with a non-(Imager image object). Previously it would typically
154 crash.
155 https://rt.cpan.org/Ticket/Display.html?id=117878
156
157 - improve the documentation of the jpegquality parameter when
158 writing JPEG files.
159
160 - add code to mitigate CVE-2016-1238, Imager will no longer search the
161 default current directory entry in @INC when searching for file
162 format support modules.

166
167It's now been ten years since I switched to the new Changes file in
168release 0.55.
169
cd0109d8
TC
170 - revert the ivdformat probes, they don't work as is and trying to
171 fix them is too much work for now.
172

TC
173Imager 1.004_004 - 15 Apr 2016
174================
175
9c45cc49
TC
176 - test that the ivdformat from Config is correct and look for a valid
177 one if it isn't.
178 For the strange Win32 failures.
179
180 - fix a copy and paste error in pod in samples/samp-form.cgi
181

TC
182Imager 1.004_003 - 23 Mar 2016
183================
184
bd2d657d
TC
185 - add some extra error reporting to the I/O layers tests, this might
186 help catch a failure seen on Win32.

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

197Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
198================
199
08914ed1
TC
200 - re-work the t/200-file/400-basic.t to correctly handle failures
201 It's custom ok() function didn't have a prototype and didn't use scalar().
202 This caused ok() to use the note instead of the value being tested when
203 the method called returned an empty list. For an example of the problem
e6226ce5 204 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 205
a2791e47
TC
206 - remove some noise from when Imager tried to work with bugs in old
207 versions of giflib. I can't do much about the new bugs.
08914ed1 208
e6226ce5
TC
209 - the new autolevels filter (Imager 0.99) used an integer for the
210 sample scaling factor which caused the top output level to be too
211 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
212 https://rt.cpan.org/Ticket/Display.html?id=111871
213
e6226ce5 214 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
215 minimum and maximum luminance from the histogram. This slightly
216 reduced the contrast of the output image.
217 https://rt.cpan.org/Ticket/Display.html?id=111871
218
219 - the new autolevels filter now uses a lookup table for 8-bit images
220 to avoid a floating point multiply for each sample.
221 https://rt.cpan.org/Ticket/Display.html?id=111871
222
e6226ce5
TC
223 - fixed several memory leaks detected by valgrind:
224
225 - addcolors() leaked the temporary array of colors supplied to the
226 internal API
227
228 - make_palette() leaked the temporary image array (not the images
229 themselves) passed to the internal API.
230
231 - combine()/i_combine() leaked its working row buffers
232
233 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
234 buffer if there were too many colors
235
236 - getcolorcount()/i_count_colors() leaked the sample buffer if
237 there were too many colors.
238
239 - the nearest_color filter (undocumented until I find a use for it)
240 leaked both temporaries passed to the API and internal buffers
241
a2791e47
TC
242 - the internal process of upgrading a paletted image to a direct
243 color image would leak a context object reference count.
244
245 - a write failure when writing to a GIF file could leak memory.
246
247 - failing to write to a 1-bit/pixel ICO image could leak memory.
248
249 - Imager no longer deliberately leaks the context object from the
250 initial thread. This was done to ensure there was always a context
251 object available, but the code that needed that now handles the
252 lack correctly,
253
e6226ce5
TC
254 - fixed some uninitialized memory usage detected by valgrind:
255
256 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
257 i_matrix_transform_bg() didn't initialize a working color value
258 if there was zero pixel coverage.
259
260 - i_ft2_cp() didn't initialize the complete color when producing an
261 intermediate image. This caused uninitialized value usage when
262 logging the color.

264Imager 1.004 - 8 Nov 2015
265============
266
5ebfb369
TC
267 - Imager::Color::Table is now pre-loaded by the preload() method.
268 https://rt.cpan.org/Ticket/Display.html?id=104896
269
270 - fix an assertion triggered under perl 5.23.4.
271 Thanks to A. Sinan Unur for the report and the patch.
272
7b638aba
TC
273 - Imager->new can now be used to read raw image files.

276
277 - deal with output changes from Pod::Spell

TC
280Imager 1.003 - 12 May 2015
281============
282
0fda3cfd
TC
283 - update 1.002 release notes to include the center change for filled
284 circle drawing.
285
286 - flood_fill() would escape beyond a 4-connected space under some
287 circumstances.
288 Added many more flood_fill() tests.

TC
291Imager 1.002 - 3 Apr 2015
292============
293
334b8922
TC
294 - drawing anti-aliased filled circles is now 10 to 50 times faster
295 depending on the size of the circle.
0fda3cfd
TC
296 This also changed the center from being the center of the pixel to
297 being the top left of the pixel to match the filled arcs drawn by
298 arc().
334b8922
TC
299 https://rt.cpan.org/Ticket/Display.html?id=101682
300
301 - enhancements to polygon filling:
302
303 - added a mode parameter to control how overlapping regions behave
304
305 - added a polypolygon() method to fill more than one polygon at a
306 time
307
308 - polygon filling is now exposed through the API.
309
45c8e262
TC
310 - added colormodel(), alphachannel() and colorchannels() methods.
311 These were added for two reasons:
312
313 - a future version of Imager may allow the number of channels in
314 an image to not directly represent the color model of an image.
315 eg. a greyscale TIFF image with multiple alpha channels.
316
317 - a future version of Imager may allow an image to be read without
318 translation, for example a TIFF file that contains measurements
0fda3cfd 319 from an instrument. Currently Imager transforms the samples into
d96c4de8 320 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
321 the value back.
322
323 An untranslated image would be unusable as image data, so
324 colormodel() would return "unknown" in this case.
325
326 Similarly a CMYK image might be returned as an "unknown" color
327 model image, if the caller chooses to disable translation to
328 RGB.

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

405Imager 0.99 - 25 Jun 2014
406===========
407
dce1523b
TC
408 - Imager::IO->new_buffer() (and hence Imager->read()'s data
409 parameter) now accepts a reference to a scalar as well as just a
410 plain scalar.
6a160bce 411 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
412
413 - Imager::IO->new_buffer() now always makes a copy of the passed in
414 buffer to avoid problems with temporary objects used for the return
415 value of SvPVbyte().

421 - load plugins from absolute paths on Android
422 Thanks to Brian Fraser.
423 https://rt.cpan.org/Ticket/Display.html?id=93272
424
6a160bce
TC
425 - added the jpeg_optimize parameter for writing JPEG files. This can
426 significantly reduce file sizes, but uses more memory and time.
427 https://rt.cpan.org/Ticket/Display.html?id=94292
428
14fd9e5d
TC
429 - the autolevels filter now works on the luminosity of the image
430 rather then working per channel. The old autolevels filter is
431 still available as "autolevels_skew".

434 - Imager::File::PNG now supports libpng 1.6.10.
435 1.6.10 changed CRC errors from benign errors to normal errors,
436 which broke the test which used CRC errors to check for benign
437 error support. Switched to using a 1-bit grey-scale image with a
438 palette to test for benign errors.

444Incompatible changes:
445
446 - the return value of setpixel() has changed.
447
448 Previously the return values for undrawable pixels vs caller errors
449 changed depending on whether you used the multiple pixel calling
450 mechanism, or the single pixel mechanism.
451
452 Now:
453
454 - for an invalid parameter, such as an unknown colour, or missing
455 parameter, an empty list (or undef in scalar context) is
456 returned, and errstr() is set,
457
458 - otherwise the number of pixels drawn is returned. If none of
459 the pixels could be drawn (they were all outside the image), "0
460 but true" is returned.

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

526 Mixed SampleFormat are handled incorrectly, since libtiff returns

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

794 the API level compiled into a loadable module such as
795 Imager::File::GIF doesn't match that of Imager. Previously it

TC
818 - when downconverting samples (eg. from floating point to 8 bit)
819 Imager now rounds the sample value rather than attempting to
820 allocate input values over output values equally. The old
821 behaviour had the probably surprising effect of converting a
822 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
823 2.
824 This may result in slightly different 8 or 16-bit output images.

852 https://rt.cpan.org/Ticket/Display.html?id=74043
853
854 - if a probe includes testcode, Imager::Probe now checks that code as
855 part of the process of checking each configuration rather than as a
856 post test of the found configuration. This allows alternate

934 - setsamples() is now a true complement to getsamples() - it can
935 write 8-bit or floating point samples from a scalar or array
936 reference. This adds i_psamp() and i_psampf() to the C level API.
937
938 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
939 changed to make better use of the typemap, but these aren't part of
940 the perl level API anyway. There were no changes to the C level
941 interfaces to these functions.

1096 - io_glue I/O buffering re-work:
1097
1098 - reorganize io_glue to do it's own buffering by default
1099
1100 - the unbuffered functions are available as i_io_raw_read() (or
1101 raw_read() from perl) etc but are not recommended for typical
1102 use.
1103
1104 - use the new i_io_peekn() when checking for file magic to avoid
1105 seek, allowing Imager to detect the file type and read the file
1106 from an unseekable stream (for formats that don't use random
1107 access)
1108
1109 - added several new I/O layer API functions.
1110
1111 - fix the TGA performance problem, most noticably on Win32
1112 https://rt.cpan.org/Ticket/Display.html?id=70037
1113
1114 - TIFF now uses wrapper functions of the correct types to avoid casts
1115 https://rt.cpan.org/Ticket/Display.html?id=69912
1116
1117 - the callback IO object did its own buffering, controlled by the
1118 maxbuffer parameter supplied to the read() and write() methods.
1119 This buffering has been removed, to avoid redundancy with the
1120 common io_glue buffering. This also avoids a bug in that code
1121 which could rarely pass a zero length to the read callback and
1122 then panic about the result.
1123
1124 - the callback IO object now tests the result of calling the close
1125 callback, which should return true for success.
1126
1127 - the PNM reader did its own buffering. This buffering has been
1128 removed to avoid redundancy with the common io_glue buffering.
1129
1130 - previously the read handlers for fd and callback I/O layers would
1131 call the underlying interface (POSIX read or your supplied callback)
1132 until it filled the buffer. It now only makes one call.
1133
1134 - added public constructors for I/O layer objects (see Imager::IO)
1135
1136 - all core file handlers now use the i_io_foo() wrappers to gain
1137 access to buffered I/O rather than calling the I/O layer
1138 callbacks directly.
1139
1140 - all core file handlers now check for error on close.
1141
1142 - Backward compatibility: if you hava custom file handlers, you can
1143 use i_io_write() etc since they're available as macros in older
1144 versions of Imager.
1145
1146 - eliminate the final remnants of io_glue_commit_types().
1147
1148 - bump IMAGER_API_VERSION, since the above may break assumptions.
1149
1150 - removed the long unused i_gen_reader() and i_gen_writer() utility
1151 functions.

TC
1215
1216Massive types re-work:
1217
1218 - the type used internally for pixel co-ordinates and image sizes is
1219 now 64-bit on 64-bit platforms (at least sane ones).
1220
1221 - size_t is now used consistently for memory block sizes.
1222
1223 - since this changes the binary interface, the Imager API version has
1224 been incremented. Any module that uses the API will need to be
1225 rebuilt. In most cases that will be enough, but calls to any APIs
1226 that take a pointer to image sizes may need source changes.
1227
1228 - you should be able to create very large images on 64-bit systems,
1229 if you have enough memory. Successfully created a 32768 x 49192 x
1230 3 channel image, filled with a tiled image and scaled it. The
1231 unscaled image was also successfully saved to a JPEG.
1232
1233 - check the image size before attempting to write BMP, GIF, JPEG,
1234 PNG, SGI, TGA, TIFF images.
1235
1236 - correctly handle reading TGA images over 32767 pixels wide or tall.
1237
1238Incidental changes:
1239
1240 - the gif_left and gif_top tags are now clamped to non-negative
1241 values when writing a GIF image.
1242
1243 - removed dead callback read/write code
1244
1245The default maximum memory size when reading files is now 1G.

1855 - Possible security issue: The floating point sample path for image
1856 based fills had a buffer overflow. This would overwrite the end of

1861 - check that the result of fileno($fh) is defined rather than simply
1862 true when read() or write() is supplied with an fh parameter.
1863 http://rt.cpan.org/Ticket/Display.html?id=35139
1864
1865 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1866 resulting in a SIGSEGV when attempting to scale an image to a size
1867 too large to fit in memory. This is a NULL pointer access issue,
1868 not a buffer overflow.
1869 Added a check for the failure.
1870 scale_calculate() (and hence scale()) will now fail if any of the

1883This release primarily contains changes to improve ease of use -
1884rather than you having to convert images to the appropriate number of
1885channels, Imager handles it internally. How to handle drawing colors
1886and the default combine mode is a thornier problem left for some other
1887release.

TC
1892 - moved the imtoc.perl code into Imager::Preprocess
1893
1894 - paste() and rubthrough() now adapt the source image data to the
1895 destination, so you can now safely paste/rubthrough from greyscale
1896 images to color images or back, or from alpha channel images to
1897 noalpha channels or back.
1898 https://rt.cpan.org/Ticket/Display.html?id=30908
1899
1900 - rubthrough() now falls back to pasting when the source doesn't have
1901 an alpha channel. This effectively treats the source as having a
1902 max alpha channel, the right thing to do.
1903 http://rt.cpan.org/Ticket/Display.html?id=29944
1904
1905 - re-worked most of the area filling code to use a common set of
1906 functions when filling.
1907 Corrected normal combine mode.
1908 Rewrote most of the combine modes to match the way the SVG draft
1909 defines them with respect to a translucent source and destination.
1910 Added tests for translucent source and destination.
1911 Added tests to check 8-bit/sample and double/sample combines work
1912 similarly.

1948 - some TGA images weren't being detected correctly as TGA images
1949 https://rt.cpan.org/Ticket/Display.html?id=32925
1950
1951 - handling of the left-over bit for 16-bit/pixel TGA images has been
1952 changed to match the behaviour of the GIMP. Previously the bit
1953 being set was treated as an opaque pixel, but one user reported a
1954 problem with loading such an image. I haven't been able to find any
1955 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1956 I'll match it's behaviour. See issue 114913 in the GIMP's
1957 bugzilla.

1967 - the old dynaload code used Mach API functions to load dynamic
1968 libraries on Mac OS X. These APIs have been deprecated in OS X
1969 10.5 and were causing some build problems.

1971 will need version 10.3 or later of OS X.

2203 - reworked library probing, we can now set more than one probe
2204 function for a library. Disabled the default (non-freetype-config)
2205 library probe and added an extra probe function that searches for
2206 both ft2build.h and whatever it includes, and adds -I as needed.

2275Imager 0.55 - 16 Dec 2006
2276===========
2277
2278This is primarily a bug fix release.
2279
2280Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2281
2282There is one new feature:
2283
2284 - the Win32 font driver now supports UTF8 (RT 22166)
2285 http://www.cpanforum.com/threads/3276
2286 http://rt.cpan.org/Ticket/Display.html?id=22166
2287
2288Several bugs were fixed:
2289
2290 - the string() method would not output the string "0"
2291 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2292
2293 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2294 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2295
2296 - the gif_disposal and gif_user_input tags weren't being read from
2297 the file correctly
2298 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2299
2300 - gif.c was failing to build under MSVC
2301 http://rt.cpan.org/Ticket/Display.html?id=23922
2302
2303 - in some cases strings passed to the string() method were treated as
2304 terminated by NUL (chr 0)
2305 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2306
2307 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2308 that's the default build name for zlib on Win32.
2309 http://rt.cpan.org/Ticket/Display.html?id=23064
2310
2311 - search $Config{incpath} for headers too, which we should have been
2312 doing all along.
2313
2314Win32 font driver fixes:
2315
2316 - the global descent value from bounding box was the wrong sign
2317 http://www.cpanforum.com/threads/3276
2318
2319 - if the first or last glyph overflowed the left or right side of the
2320 advance width they would be clipped
2321
2322
2323Imager 0.54 - 14 Sep 2006
2324===========
2325
2326This is primarily a feature release:
2327
2328 - a new qtype value 'mixing' has been added to the scale()
2329 method. This is faster than 'normal', slower than 'preview'. This
2330 is based on the method used by pnmscale, and seems to produce less
2331 blurry results than normal.
2332 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2333
2334 - the rubthrough() method can now render onto images with an alpha
2335 channel.
2336 http://rt.cpan.org/Ticket/Display.html?id=20678
2337
2338 - the read_multi() method now falls back to calling doing a single
2339 image read via the read() method and write_multi() will now fall
2340 back to calling write() if a single image is supplied. This means
2341 you can simply call the read_multi() or write_multi() functions
2342 without having to check if the type is formatted by that method.
2343 http://rt.cpan.org/Ticket/Display.html?id=19457
2344 http://rt.cpan.org/Ticket/Display.html?id=19458
2345
2346 - the GIF loop extension can now be written. If you don't have
2347 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2348 should upgrade.
2349 http://rt.cpan.org/Ticket/Display.html?id=21185
2350
2351 - getscanline() and setscanline() can now read/write palette index
2352 based data from/to the image for paletted images, by setting type to
2353 'index'.
2354 http://rt.cpan.org/Ticket/Display.html?id=20338
2355
2356 - we no longer hassle you to disable GIF support
2357 http://rt.cpan.org/Ticket/Display.html?id=20687
2358
2359 - minor documentation fixes
2360
2361
2362Imager 0.53 - 26 Jul 2006
2363===========
2364
2365This is a bugfix release.
2366
2367Some test code was left in a code path not covered by the test
2368suite. A test was added to cover this code path and the test code was
2369removed.
2370http://rt.cpan.org/Public/Bug/Display.html?id=20705
2371
2372
2373Imager 0.52 - 25 Jul 2006
2374===========
2375
2376This is primarily a feature release, but contains a fair few bug
2377fixes, new features:
2378
2379 - ability to read and write MS Windows ICO and CUR files
2380
2381 - you can now add file format plugins to support new file formats
2382
2383 - add POD coverage tests
2384
2385 - setcolors() and addcolors() now accept color names and so on
2386 instead of requiring Imager::Color objects.
2387 http://rt.cpan.org/Ticket/Display.html?id=20056
2388
2389 - flood_fill() can now fill to a specified border color instead of
2390 just to the area the same color as the seed.
2391 http://rt.cpan.org/Ticket/Display.html?id=19618
2392
2393
2394Bug fixes:
2395
2396 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2397 calculating the advance width.
2398 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2399
2400 - bounding_box for the T1 driver wasn't including leading and
2401 trailing spaces in the bounding box as the other drivers did, it also
2402 produced strange results for empty strings or strings containing only
2403 spaces
2404
2405 - when reading CMYK jpeg images they were being transferred to the
2406 image object as is, producing a four channel image. It only looked ok
2407 due to an old still unfixed Photoshop bug. We now convert from the
2408 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2409 http://rt.cpan.org/Ticket/Display.html?id=20416
2410
2411 - reading a CYMK TIFF would result in a 4 channel image, reading any
2412 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2413 result in an error.
2414 http://rt.cpan.org/Ticket/Display.html?id=20415
2415
2416 - added /usr/local/include to the default include search path, since
2417 we were already searching /usr/local/lib for libraries.
2418
2419And various minor fixes and documentation updates.
2420
2421
2422Imager 0.51 - 23 Apr 2006

2426 a crash
2427 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2428
2429 - fix mis-processing of the src_maxx and src_maxy parameters of the
2430 paste() method
2431 http://rt.cpan.org/Public/Bug/Display.html?id=18712

2442 or 4 channel image to jpeg or a 2 channel image to tga where the
2443 output is an in-memeory buffer.
2444 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2445
2446 - fixes an incorrect pointer parameter in the PNG code
2447 http://rt.cpan.org/Public/Bug/Display.html?id=18051
2448
2449 - skip Inline::C tests when building in a directory with spaces
2450 http://rt.cpan.org/Public/Bug/Display.html?id=18049
