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
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
6fa51f9c
TC
112 - i_img_info() (C API) no longer tries to handle a NULL image object
113 pointer. CID 185298.
114
a3b721bb
TC
115[1] The first two build submissions ended up at the end of a ~400
116build queue, and seemed to have been cancelled by Coverity. A build
117submitted on NYE went through in minutes.

TC
119Imager 1.008 - 31 Dec 2018
120============
121
75e155e1 122 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
123 This allows file formats that store EXIF data as blobs similarly
124 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 125
b5bbf161 126 - added some more file extensions to image file type mappings
75e155e1
TC
127
128 - added add_type_extensions() class method
129

ac3e79fb
TC
144Imager 1.006 - 26 Aug 2017
145============
146
ba7ddbae
TC
147 - the internal i_errors() function now correctly allocates the stack
148 space needed for its result.
149 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
150
151 - t/100-base/020-color.t now uses Imager::Test's test functions
152 instead of its own.
153 https://rt.cpan.org/Ticket/Display.html?id=111993
154
344dda51
TC
155 - write_multi() now returns an error result (a false value) if called
156 with a non-(Imager image object). Previously it would typically
157 crash.
158 https://rt.cpan.org/Ticket/Display.html?id=117878
159
160 - improve the documentation of the jpegquality parameter when
161 writing JPEG files.
162
163 - add code to mitigate CVE-2016-1238, Imager will no longer search the
164 default current directory entry in @INC when searching for file
165 format support modules.

169
170It's now been ten years since I switched to the new Changes file in
171release 0.55.
172
cd0109d8
TC
173 - revert the ivdformat probes, they don't work as is and trying to
174 fix them is too much work for now.
175
6f1cbfed
TC
176Imager 1.004_004 - 15 Apr 2016
177================
178
9c45cc49
TC
179 - test that the ivdformat from Config is correct and look for a valid
180 one if it isn't.
181 For the strange Win32 failures.
182
183 - fix a copy and paste error in pod in samples/samp-form.cgi
184

TC
185Imager 1.004_003 - 23 Mar 2016
186================
187
bd2d657d
TC
188 - add some extra error reporting to the I/O layers tests, this might
189 help catch a failure seen on Win32.

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

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

267Imager 1.004 - 8 Nov 2015
268============

TC
270 - Imager::Color::Table is now pre-loaded by the preload() method.
271 https://rt.cpan.org/Ticket/Display.html?id=104896
272
273 - fix an assertion triggered under perl 5.23.4.
274 Thanks to A. Sinan Unur for the report and the patch.
275
7b638aba
TC
276 - Imager->new can now be used to read raw image files.

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

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

5dab5b9a
TC
374 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
375 the blue channel in the generated palette, and allow each color
376 component to be in the range 100..255 instead of just 100..254.
377 Thanks to Ralf Neubauer.
378 https://rt.cpan.org/Ticket/Display.html?id=97086
379
380 - revert "improved the XS for i_io_read() and i_io_raw_read()"
381 This caused problems with older perls and didn't provide much of a
382 performance improvement.
383
5bf25bc2 384 - support Inline 0.57 and later.
6d47a6af 385 Inline 0.57 changed the "with" interface.

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

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

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

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

467Other changes:

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

529 Mixed SampleFormat are handled incorrectly, since libtiff returns

785 matrix to use the distance between the outlier pixels rather than
786 the pixel dimensions (ie. dimension-1).
787 With all of this the output of rotate(degrees => 270) on an 8-bit

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

TC
821 - when downconverting samples (eg. from floating point to 8 bit)
822 Imager now rounds the sample value rather than attempting to
823 allocate input values over output values equally. The old
824 behaviour had the probably surprising effect of converting a
825 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
826 2.
827 This may result in slightly different 8 or 16-bit output images.

829 - BI_BITFIELD BMP images were handled incorrectly, both in

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

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

1099 - io_glue I/O buffering re-work:
1100
1101 - reorganize io_glue to do it's own buffering by default
1102
1103 - the unbuffered functions are available as i_io_raw_read() (or
1104 raw_read() from perl) etc but are not recommended for typical
1105 use.
1106
1107 - use the new i_io_peekn() when checking for file magic to avoid
1108 seek, allowing Imager to detect the file type and read the file
1109 from an unseekable stream (for formats that don't use random
1110 access)
1111
1112 - added several new I/O layer API functions.
1113
1114 - fix the TGA performance problem, most noticably on Win32
1115 https://rt.cpan.org/Ticket/Display.html?id=70037
1116
1117 - TIFF now uses wrapper functions of the correct types to avoid casts
1118 https://rt.cpan.org/Ticket/Display.html?id=69912
1119
1120 - the callback IO object did its own buffering, controlled by the
1121 maxbuffer parameter supplied to the read() and write() methods.
1122 This buffering has been removed, to avoid redundancy with the
1123 common io_glue buffering. This also avoids a bug in that code
1124 which could rarely pass a zero length to the read callback and
1125 then panic about the result.
1126
1127 - the callback IO object now tests the result of calling the close
1128 callback, which should return true for success.
1129
1130 - the PNM reader did its own buffering. This buffering has been
1131 removed to avoid redundancy with the common io_glue buffering.
1132
1133 - previously the read handlers for fd and callback I/O layers would
1134 call the underlying interface (POSIX read or your supplied callback)
1135 until it filled the buffer. It now only makes one call.
1136
1137 - added public constructors for I/O layer objects (see Imager::IO)
1138
1139 - all core file handlers now use the i_io_foo() wrappers to gain
1140 access to buffered I/O rather than calling the I/O layer
1141 callbacks directly.
1142
1143 - all core file handlers now check for error on close.
1144
1145 - Backward compatibility: if you hava custom file handlers, you can
1146 use i_io_write() etc since they're available as macros in older
1147 versions of Imager.
1148
1149 - eliminate the final remnants of io_glue_commit_types().
1150
1151 - bump IMAGER_API_VERSION, since the above may break assumptions.
1152
1153 - removed the long unused i_gen_reader() and i_gen_writer() utility
1154 functions.

1217Development release as a sanity check for the types re-work.
8d14daab
TC
1218
1219Massive types re-work:
1220
1221 - the type used internally for pixel co-ordinates and image sizes is
1222 now 64-bit on 64-bit platforms (at least sane ones).
1223
1224 - size_t is now used consistently for memory block sizes.
1225
1226 - since this changes the binary interface, the Imager API version has
1227 been incremented. Any module that uses the API will need to be
1228 rebuilt. In most cases that will be enough, but calls to any APIs
1229 that take a pointer to image sizes may need source changes.
1230
1231 - you should be able to create very large images on 64-bit systems,
1232 if you have enough memory. Successfully created a 32768 x 49192 x
1233 3 channel image, filled with a tiled image and scaled it. The
1234 unscaled image was also successfully saved to a JPEG.
1235
1236 - check the image size before attempting to write BMP, GIF, JPEG,
1237 PNG, SGI, TGA, TIFF images.
1238
1239 - correctly handle reading TGA images over 32767 pixels wide or tall.
1240
1241Incidental changes:
1242
1243 - the gif_left and gif_top tags are now clamped to non-negative
1244 values when writing a GIF image.
1245
1246 - removed dead callback read/write code
1247
1248The default maximum memory size when reading files is now 1G.

1869 resulting in a SIGSEGV when attempting to scale an image to a size
1870 too large to fit in memory. This is a NULL pointer access issue,

1886This release primarily contains changes to improve ease of use -
1887rather than you having to convert images to the appropriate number of
1888channels, Imager handles it internally. How to handle drawing colors
1889and the default combine mode is a thornier problem left for some other
1890release.

TC
1895 - moved the imtoc.perl code into Imager::Preprocess
1896
1897 - paste() and rubthrough() now adapt the source image data to the
1898 destination, so you can now safely paste/rubthrough from greyscale
1899 images to color images or back, or from alpha channel images to
1900 noalpha channels or back.
1901 https://rt.cpan.org/Ticket/Display.html?id=30908
1902
1903 - rubthrough() now falls back to pasting when the source doesn't have
1904 an alpha channel. This effectively treats the source as having a
1905 max alpha channel, the right thing to do.
1906 http://rt.cpan.org/Ticket/Display.html?id=29944
1907
1908 - re-worked most of the area filling code to use a common set of
1909 functions when filling.
1910 Corrected normal combine mode.
1911 Rewrote most of the combine modes to match the way the SVG draft
1912 defines them with respect to a translucent source and destination.
1913 Added tests for translucent source and destination.
1914 Added tests to check 8-bit/sample and double/sample combines work
1915 similarly.

1954 - handling of the left-over bit for 16-bit/pixel TGA images has been
1955 changed to match the behaviour of the GIMP. Previously the bit
1956 being set was treated as an opaque pixel, but one user reported a
1957 problem with loading such an image. I haven't been able to find any
1958 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1959 I'll match it's behaviour. See issue 114913 in the GIMP's
1960 bugzilla.

1970 - the old dynaload code used Mach API functions to load dynamic
1971 libraries on Mac OS X. These APIs have been deprecated in OS X
1972 10.5 and were causing some build problems.

1974 will need version 10.3 or later of OS X.

2206 - reworked library probing, we can now set more than one probe
2207 function for a library. Disabled the default (non-freetype-config)
2208 library probe and added an extra probe function that searches for
2209 both ft2build.h and whatever it includes, and adds -I as needed.

2278Imager 0.55 - 16 Dec 2006
2279===========
2280
2281This is primarily a bug fix release.
2282
2283Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2284
2285There is one new feature:
2286
2287 - the Win32 font driver now supports UTF8 (RT 22166)
2288 http://www.cpanforum.com/threads/3276
2289 http://rt.cpan.org/Ticket/Display.html?id=22166
2290
2291Several bugs were fixed:
2292
2293 - the string() method would not output the string "0"
2294 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2295
2296 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2297 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2298
2299 - the gif_disposal and gif_user_input tags weren't being read from
2300 the file correctly
2301 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2302
2303 - gif.c was failing to build under MSVC
2304 http://rt.cpan.org/Ticket/Display.html?id=23922
2305
2306 - in some cases strings passed to the string() method were treated as
2307 terminated by NUL (chr 0)
2308 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2309
2310 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2311 that's the default build name for zlib on Win32.
2312 http://rt.cpan.org/Ticket/Display.html?id=23064
2313
2314 - search $Config{incpath} for headers too, which we should have been
2315 doing all along.
2316
2317Win32 font driver fixes:
2318
2319 - the global descent value from bounding box was the wrong sign
2320 http://www.cpanforum.com/threads/3276
2321
2322 - if the first or last glyph overflowed the left or right side of the
2323 advance width they would be clipped
2324
2325
2326Imager 0.54 - 14 Sep 2006
2327===========
2328
2329This is primarily a feature release:
2330
2331 - a new qtype value 'mixing' has been added to the scale()
2332 method. This is faster than 'normal', slower than 'preview'. This
2333 is based on the method used by pnmscale, and seems to produce less
2334 blurry results than normal.
2335 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2336
2337 - the rubthrough() method can now render onto images with an alpha
2338 channel.
2339 http://rt.cpan.org/Ticket/Display.html?id=20678
2340
2341 - the read_multi() method now falls back to calling doing a single
2342 image read via the read() method and write_multi() will now fall
2343 back to calling write() if a single image is supplied. This means
2344 you can simply call the read_multi() or write_multi() functions
2345 without having to check if the type is formatted by that method.
2346 http://rt.cpan.org/Ticket/Display.html?id=19457
2347 http://rt.cpan.org/Ticket/Display.html?id=19458
2348
2349 - the GIF loop extension can now be written. If you don't have
2350 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2351 should upgrade.
2352 http://rt.cpan.org/Ticket/Display.html?id=21185
2353
2354 - getscanline() and setscanline() can now read/write palette index
2355 based data from/to the image for paletted images, by setting type to
2356 'index'.
2357 http://rt.cpan.org/Ticket/Display.html?id=20338
2358
2359 - we no longer hassle you to disable GIF support
2360 http://rt.cpan.org/Ticket/Display.html?id=20687
2361
2362 - minor documentation fixes
2363
2364
2365Imager 0.53 - 26 Jul 2006
2366===========
2367
2368This is a bugfix release.
2369
2370Some test code was left in a code path not covered by the test
2371suite. A test was added to cover this code path and the test code was
2372removed.
2373http://rt.cpan.org/Public/Bug/Display.html?id=20705
2374
2375
2376Imager 0.52 - 25 Jul 2006
2377===========
2378
2379This is primarily a feature release, but contains a fair few bug
2380fixes, new features:
2381
2382 - ability to read and write MS Windows ICO and CUR files
2383
2384 - you can now add file format plugins to support new file formats
2385
2386 - add POD coverage tests
2387
2388 - setcolors() and addcolors() now accept color names and so on
2389 instead of requiring Imager::Color objects.
2390 http://rt.cpan.org/Ticket/Display.html?id=20056
2391
2392 - flood_fill() can now fill to a specified border color instead of
2393 just to the area the same color as the seed.
2394 http://rt.cpan.org/Ticket/Display.html?id=19618
2395
2396
2397Bug fixes:
2398
2399 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2400 calculating the advance width.
2401 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2402
2403 - bounding_box for the T1 driver wasn't including leading and
2404 trailing spaces in the bounding box as the other drivers did, it also
2405 produced strange results for empty strings or strings containing only
2406 spaces
2407
2408 - when reading CMYK jpeg images they were being transferred to the
2409 image object as is, producing a four channel image. It only looked ok
2410 due to an old still unfixed Photoshop bug. We now convert from the
2411 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2412 http://rt.cpan.org/Ticket/Display.html?id=20416
2413
2414 - reading a CYMK TIFF would result in a 4 channel image, reading any
2415 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2416 result in an error.
2417 http://rt.cpan.org/Ticket/Display.html?id=20415
2418
2419 - added /usr/local/include to the default include search path, since
2420 we were already searching /usr/local/lib for libraries.
2421
2422And various minor fixes and documentation updates.
2423
2424
2425Imager 0.51 - 23 Apr 2006

2429 a crash
2430 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2431
2432 - fix mis-processing of the src_maxx and src_maxy parameters of the
2433 paste() method
2434 http://rt.cpan.org/Public/Bug/Display.html?id=18712

2439
2440
2441Imager 0.50 - 29 Mar 2006
2442===========
2443
2444 - CRITICAL: fixes a segmentation fault from attempting to write a 2
2445 or 4 channel image to jpeg or a 2 channel image to tga where the
2446 output is an in-memeory buffer.
2447 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2448
2449 - fixes an incorrect pointer parameter in the PNG code
2450 http://rt.cpan.org/Public/Bug/Display.html?id=18051
2451
2452 - skip Inline::C tests when building in a directory with spaces
2453 http://rt.cpan.org/Public/Bug/Display.html?id=18049
