TC
6Critical issue:
7
8 - drawing a filled, anti-aliased circle to the left or right of the
9 image (not within the image at all) would cause a buffer overflow.
10 https://rt.cpan.org/Ticket/Display.html?id=128208
11
a3b721bb
TC
12General changes:
13
14 - to_paletted() and make_palette() now fail (with an error in
15 errstr()) if invalid quantization parameters are supplied.
16
35ec3a87
TC
17 - map() would corrupt a channel if there was a gap in the arrayref of
18 channels. Detected by Coverity. CID 185300.
19
5824f4c2
TC
20 - most numeric parameters to the XS implementation now throw an
21 exception if supplied an unoverloaded reference.
22 https://rt.cpan.org/Ticket/Display.html?id=128208
23
e32d3a7c
TC
24Coverity finally finished a build[1], fixed several of the problems
25found. Coverity went down before I could finish working through them.
1791cbdb 26
8445279e
TC
27High severity:
28
1791cbdb 29 - reading a color-mapped TGA file with an id string would cause a
8445279e 30 double-free if the palette was truncated. CID 185317.
1791cbdb 31
6494c395
TC
32 - mixing scaling to sizes where the accumulator row, the working
33 output row or the working input row didn't fit into the address
34 space could result in memory leaks. This can probably only be
8445279e 35 reproduced on very wide floating-point sample images. CID 185318.
6494c395 36
fc24ca5f 37 - convert an array style function parameter pointer to pointer style
3d7b055c 38 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 39 CID 185343.
3d7b055c 40
8445279e 41 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 42
20c297d4 43 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 44 implementation. CID 185303.
20c297d4 45
fc24ca5f 46 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 47 drawing (it should always end up being set.) CID 185341.
fc24ca5f 48
f7675b46 49 - addi style makemap could potentially read one past the end of an
8445279e 50 array. CID 185337.
f7675b46 51
58ec1fde
TC
52 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
53 would result in read beyond the end of the built-in hatch array.
54 Negative values (which Coverity didn't complain about) could also
8445279e 55 cause problems. CID 185331.
58ec1fde 56
b7346865
TC
57 - the Imager::Color set_internal() interal method no longer
58 calls the over-complicated ICL_set_internal() (which is retained
59 only for the old API.) Coverity complained that this leaked, but
60 this could only occur with an invalid (NULL pointer) color object.
8445279e 61 CID 185323.
b7346865 62
785364c1
TC
63 - the underlying implementation of the map() method could read before
64 the beginning on an allocated array if supplied with inconsistent
65 parameters, which Coverity complained about. No Imager code calls
66 that function with inconsistent parameters, but a
8445279e 67 belt-and-suspenders check was added. CID 185315.
785364c1 68
eb7e48c9
TC
69 - Coverity complained a call to i_getcolors(), used by the
70 implementation of the is_bilevel() method could leave the fetched
8445279e 71 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 72
c1c8b1e9
TC
73 - a numeric combining mode of 13 (eg. as a parameter to
74 Imager::Fill->new())could cause an invalid array read in
75 i_get_combine() due to a fencepost error in validating the combine
8445279e 76 number. CID 185299.
c1c8b1e9 77
59fd0c6b 78Lower severity (according to Coverity):
c4fd43be
TC
79
80 - avoid an unneeded EXTEND() call when the FT1 has_chars()
81 implementation returns 0. CID 185350.
82
83 - avoid accessing a possibly NULL map from MakeMapObject() in a
84 logging call. (GIF) CID 185296.
85
4615ad8d
TC
86 - gradgen() allocated the wrong amount of space (always too much) for
87 the color array. CID 185291.
88
ea3099db
TC
89 - avoid dead code in i_tt_glyph_names(). CID 185321.
90
8b810590
TC
91 - avoid dead code in i_get_anonymous_color_histo(), which is the
92 implementation of getcolorusage(). CID 185327.
93
4eb9a521
TC
94 - avoid dead code in i_ft2_glyph_name(), which is the implementation
95 of glyph_names() for FT2. CID 185342.
96
c028aa12
TC
97 - avoid dead code in i_t1_glyph_names(), which is the implementation
98 of glyph_names() for T1. CID 185322.
99
e7772cea
TC
100 - avoid an unneeded EXTEND() call when the FT2 has_chars()
101 implementation returns 0. CID 185292.
102
596f3eee
TC
103 - the unpack code for ICO/CUR file handling could extend 32-bit
104 unsigned values to 64-bit signed. I believe this is harmless. CID
105 185319.
106
a2ca2b80
TC
107 - remove an unneeded check when terminating the stream for JPEG
108 writing. CID 185347.
109
56ce7446
TC
110 - skip an unneeded check when freeing the combine temp buffer in the
111 fountain filter. CID 185286.
112
113 - check the combine function pointer consistently rather than the
114 combine code in one place in the fountain filter.
115
a3b721bb
TC
116 - error diffusion now validates a custom error diffusion map and reports
117 an error if it's bad. CID 185288.
118
215d9ead
TC
119 - avoid discarding the value of i_io_getc() when scanning numbers in
120 pnm.c. CID 185293.
121
9ca939d0
TC
122 - handle failure to clone the log filehandle when cloning the Imager
123 context object on thread creation. CID 185294.
124
70501294 125 - fix an unsigned comparison when converting character code to a
59fd0c6b
TC
126 glyph index with a NULL character map when calculating the glyph
127 for display for FT1. This should be rare. CID 185297.
128
129 - fix a similar bug when calculating whether a glyph is present for
130 has_chars() for FT1. CID 185302.
70501294 131
6fa51f9c
TC
132 - i_img_info() (C API) no longer tries to handle a NULL image object
133 pointer. CID 185298.
134
a2c2d400
TC
135 - re-work testing for size_t overflow for circle/random
136 super-sampling for fountain fills. CID 185304.
137
8e2e2347
TC
138 - don't check if the unsigned size passed to Imager's malloc wrapper
139 (mymalloc) is negative. Left from when that parameter was signed.
140 CID 185305.
141
0c16f204
TC
142 - make some types larger and add a cast to prevent integer overflows
143 when calculating a palette with median cut for extraordinarily
144 large images. CID 185306.
145
748bfdfc
TC
146 - don't check if the unsigned size supplied to
147 im_set_image_file_limits() is negative. CID 185307.
148
57cc9afe 149[1] The first two build submissions ended up at the end of a ~400 item
a3b721bb
TC
150build queue, and seemed to have been cancelled by Coverity. A build
151submitted on NYE went through in minutes.

TC
153Imager 1.008 - 31 Dec 2018
154============
155
75e155e1 156 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
157 This allows file formats that store EXIF data as blobs similarly
158 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 159
b5bbf161 160 - added some more file extensions to image file type mappings
75e155e1
TC
161
162 - added add_type_extensions() class method
163
b5bbf161 164Imager 1.007 - 24 Nov 2018
75e155e1
TC
165============
166
a9fa5463
TC
167 - add png_compression_level tag for writing PNG files.
168
169 - avoid flooring a second time in matrix transform interpolation.
170 https://rt.cpan.org/Ticket/Display.html?id=124001
171
434c2338
TC
172 - produce v2 metadata.
173 Includes change from the ticket and updates to sub-modules.
174 https://rt.cpan.org/Ticket/Display.html?id=127216
175
d1d8320e
TC
176 - improve error reporting for the polygon() method
177
ac3e79fb
TC
178Imager 1.006 - 26 Aug 2017
179============
180
ba7ddbae
TC
181 - the internal i_errors() function now correctly allocates the stack
182 space needed for its result.
183 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
184
185 - t/100-base/020-color.t now uses Imager::Test's test functions
186 instead of its own.
187 https://rt.cpan.org/Ticket/Display.html?id=111993
188
344dda51
TC
189 - write_multi() now returns an error result (a false value) if called
190 with a non-(Imager image object). Previously it would typically
191 crash.
192 https://rt.cpan.org/Ticket/Display.html?id=117878
193
194 - improve the documentation of the jpegquality parameter when
195 writing JPEG files.
196
197 - add code to mitigate CVE-2016-1238, Imager will no longer search the
198 default current directory entry in @INC when searching for file
199 format support modules.

TC
201Imager 1.005 - 16 Apr 2016
202============
203
204It's now been ten years since I switched to the new Changes file in
205release 0.55.
206
cd0109d8
TC
207 - revert the ivdformat probes, they don't work as is and trying to
208 fix them is too much work for now.
209
6f1cbfed
TC
210Imager 1.004_004 - 15 Apr 2016
211================
212
9c45cc49
TC
213 - test that the ivdformat from Config is correct and look for a valid
214 one if it isn't.
215 For the strange Win32 failures.
216
217 - fix a copy and paste error in pod in samples/samp-form.cgi
218
5cea6ea1
TC
219Imager 1.004_003 - 23 Mar 2016
220================
221
bd2d657d
TC
222 - add some extra error reporting to the I/O layers tests, this might
223 help catch a failure seen on Win32.

225
2f4c4539
TC
226Imager 1.004_002 - 20 Mar 2016
227================
228
735b3e7b
TC
229 - don't use the seek() method on opened() handles in
230 t/200-file/400-basic.t. In older versions of perl such handles are
231 only IO::Handle objects, not IO::File, and don't have a seek()
232 method.

TC
234Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
235================
236
08914ed1
TC
237 - re-work the t/200-file/400-basic.t to correctly handle failures
238 It's custom ok() function didn't have a prototype and didn't use scalar().
239 This caused ok() to use the note instead of the value being tested when
240 the method called returned an empty list. For an example of the problem
e6226ce5 241 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 242
a2791e47
TC
243 - remove some noise from when Imager tried to work with bugs in old
244 versions of giflib. I can't do much about the new bugs.
08914ed1 245
e6226ce5
TC
246 - the new autolevels filter (Imager 0.99) used an integer for the
247 sample scaling factor which caused the top output level to be too
248 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
249 https://rt.cpan.org/Ticket/Display.html?id=111871
250
e6226ce5 251 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
252 minimum and maximum luminance from the histogram. This slightly
253 reduced the contrast of the output image.
254 https://rt.cpan.org/Ticket/Display.html?id=111871
255
256 - the new autolevels filter now uses a lookup table for 8-bit images
257 to avoid a floating point multiply for each sample.
258 https://rt.cpan.org/Ticket/Display.html?id=111871
259
e6226ce5
TC
260 - fixed several memory leaks detected by valgrind:
261
262 - addcolors() leaked the temporary array of colors supplied to the
263 internal API
264
265 - make_palette() leaked the temporary image array (not the images
266 themselves) passed to the internal API.
267
268 - combine()/i_combine() leaked its working row buffers
269
270 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
271 buffer if there were too many colors
272
273 - getcolorcount()/i_count_colors() leaked the sample buffer if
274 there were too many colors.
275
276 - the nearest_color filter (undocumented until I find a use for it)
277 leaked both temporaries passed to the API and internal buffers
278
a2791e47
TC
279 - the internal process of upgrading a paletted image to a direct
280 color image would leak a context object reference count.
281
282 - a write failure when writing to a GIF file could leak memory.
283
284 - failing to write to a 1-bit/pixel ICO image could leak memory.
285
286 - Imager no longer deliberately leaks the context object from the
287 initial thread. This was done to ensure there was always a context
288 object available, but the code that needed that now handles the
289 lack correctly,
290
e6226ce5
TC
291 - fixed some uninitialized memory usage detected by valgrind:
292
293 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
294 i_matrix_transform_bg() didn't initialize a working color value
295 if there was zero pixel coverage.
296
297 - i_ft2_cp() didn't initialize the complete color when producing an
298 intermediate image. This caused uninitialized value usage when
299 logging the color.

TC
301Imager 1.004 - 8 Nov 2015
302============
303
5ebfb369
TC
304 - Imager::Color::Table is now pre-loaded by the preload() method.
305 https://rt.cpan.org/Ticket/Display.html?id=104896
306
307 - fix an assertion triggered under perl 5.23.4.
308 Thanks to A. Sinan Unur for the report and the patch.
309
7b638aba
TC
310 - Imager->new can now be used to read raw image files.
311 https://rt.cpan.org/Ticket/Display.html?id=106836
f7160b21 312 Thanks to Richard Kelsch for reporting this.
7b638aba
TC
313
314 - deal with output changes from Pod::Spell

TC
317Imager 1.003 - 12 May 2015
318============
319
0fda3cfd
TC
320 - update 1.002 release notes to include the center change for filled
321 circle drawing.
322
323 - flood_fill() would escape beyond a 4-connected space under some
324 circumstances.
325 Added many more flood_fill() tests.
326 https://rt.cpan.org/Ticket/Display.html?id=103786
327
647a47c9
TC
328Imager 1.002 - 3 Apr 2015
329============
330
334b8922
TC
331 - drawing anti-aliased filled circles is now 10 to 50 times faster
332 depending on the size of the circle.
0fda3cfd
TC
333 This also changed the center from being the center of the pixel to
334 being the top left of the pixel to match the filled arcs drawn by
335 arc().
334b8922
TC
336 https://rt.cpan.org/Ticket/Display.html?id=101682
337
338 - enhancements to polygon filling:
339
340 - added a mode parameter to control how overlapping regions behave
341
342 - added a polypolygon() method to fill more than one polygon at a
343 time
344
345 - polygon filling is now exposed through the API.
346
45c8e262
TC
347 - added colormodel(), alphachannel() and colorchannels() methods.
348 These were added for two reasons:
349
350 - a future version of Imager may allow the number of channels in
351 an image to not directly represent the color model of an image.
352 eg. a greyscale TIFF image with multiple alpha channels.
353
354 - a future version of Imager may allow an image to be read without
355 translation, for example a TIFF file that contains measurements
0fda3cfd 356 from an instrument. Currently Imager transforms the samples into
d96c4de8 357 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
358 the value back.
359
360 An untranslated image would be unusable as image data, so
361 colormodel() would return "unknown" in this case.
362
363 Similarly a CMYK image might be returned as an "unknown" color
364 model image, if the caller chooses to disable translation to
365 RGB.

TC
405Imager 0.99_02 - 21 Jul 2014
406==============
407
5dab5b9a
TC
408 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
409 the blue channel in the generated palette, and allow each color
410 component to be in the range 100..255 instead of just 100..254.
411 Thanks to Ralf Neubauer.
412 https://rt.cpan.org/Ticket/Display.html?id=97086
413
414 - revert "improved the XS for i_io_read() and i_io_raw_read()"
415 This caused problems with older perls and didn't provide much of a
416 performance improvement.
417
5bf25bc2 418 - support Inline 0.57 and later.
6d47a6af 419 Inline 0.57 changed the "with" interface.

471 - Imager::File::PNG now supports libpng 1.6.10.
472 1.6.10 changed CRC errors from benign errors to normal errors,
473 which broke the test which used CRC errors to check for benign
474 error support. Switched to using a 1-bit grey-scale image with a
475 palette to test for benign errors.

TC
481Incompatible changes:
482
483 - the return value of setpixel() has changed.
484
485 Previously the return values for undrawable pixels vs caller errors
486 changed depending on whether you used the multiple pixel calling
487 mechanism, or the single pixel mechanism.
488
489 Now:
490
491 - for an invalid parameter, such as an unknown colour, or missing
492 parameter, an empty list (or undef in scalar context) is
493 returned, and errstr() is set,
494
495 - otherwise the number of pixels drawn is returned. If none of
496 the pixels could be drawn (they were all outside the image), "0
497 but true" is returned.

501Other changes:
502
6ba09ab9
TC
503 - when drawing on an image with an alpha channel where the source
504 minimum is greater than zero, Imager would read from beyond the end
505 of a malloc() allocated buffer. In rare circumstances this could
506 lead to some of the source image not being written to the target
507 image, or possibly to a segmentation fault.
508 I don't believe this has any security concerns beyond that.
509
0d052fd9
TC
510 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
511 text drawn would be nonsense. This would also read beyond the end
512 of a malloced buffer.
513
13671b17

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

563 Mixed SampleFormat are handled incorrectly, since libtiff returns

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

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

TC
855 - when downconverting samples (eg. from floating point to 8 bit)
856 Imager now rounds the sample value rather than attempting to
857 allocate input values over output values equally. The old
858 behaviour had the probably surprising effect of converting a
859 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
860 2.
861 This may result in slightly different 8 or 16-bit output images.

863 - BI_BITFIELD BMP images were handled incorrectly, both in

881 - Imager::Probe can now probe for libraries with dependent libraries,
882 common for static linking, eg. libpng requires libz.
883 https://rt.cpan.org/Ticket/Display.html?id=74043
884
885 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.

888 handle a statically linked libpng.
889 https://rt.cpan.org/Ticket/Display.html?id=74043
890
891 - if a probe includes testcode, Imager::Probe now checks that code as
892 part of the process of checking each configuration rather than as a
893 post test of the found configuration. This allows alternate
894 configurations to be checked if a matching but non-working
895 configuration is found.

1133 - io_glue I/O buffering re-work:
1134
1135 - reorganize io_glue to do it's own buffering by default
1136
1137 - the unbuffered functions are available as i_io_raw_read() (or
1138 raw_read() from perl) etc but are not recommended for typical
1139 use.
1140
1141 - use the new i_io_peekn() when checking for file magic to avoid
1142 seek, allowing Imager to detect the file type and read the file
1143 from an unseekable stream (for formats that don't use random
1144 access)
1145
1146 - added several new I/O layer API functions.

1151 - TIFF now uses wrapper functions of the correct types to avoid casts
1152 https://rt.cpan.org/Ticket/Display.html?id=69912
1153
1154 - the callback IO object did its own buffering, controlled by the
1155 maxbuffer parameter supplied to the read() and write() methods.
1156 This buffering has been removed, to avoid redundancy with the
1157 common io_glue buffering. This also avoids a bug in that code
1158 which could rarely pass a zero length to the read callback and
1159 then panic about the result.
1160
1161 - the callback IO object now tests the result of calling the close
1162 callback, which should return true for success.
1163
1164 - the PNM reader did its own buffering. This buffering has been
1165 removed to avoid redundancy with the common io_glue buffering.
1166
1167 - previously the read handlers for fd and callback I/O layers would
1168 call the underlying interface (POSIX read or your supplied callback)
1169 until it filled the buffer. It now only makes one call.
1170
1171 - added public constructors for I/O layer objects (see Imager::IO)
1172
1173 - all core file handlers now use the i_io_foo() wrappers to gain
1174 access to buffered I/O rather than calling the I/O layer
1175 callbacks directly.
1176
1177 - all core file handlers now check for error on close.
1178
1179 - Backward compatibility: if you hava custom file handlers, you can
1180 use i_io_write() etc since they're available as macros in older
1181 versions of Imager.
1182
1183 - eliminate the final remnants of io_glue_commit_types().
1184
1185 - bump IMAGER_API_VERSION, since the above may break assumptions.
1186
1187 - removed the long unused i_gen_reader() and i_gen_writer() utility
1188 functions.

1251Development release as a sanity check for the types re-work.
8d14daab
TC
1252
1253Massive types re-work:
1254
1255 - the type used internally for pixel co-ordinates and image sizes is
1256 now 64-bit on 64-bit platforms (at least sane ones).
1257
1258 - size_t is now used consistently for memory block sizes.
1259
1260 - since this changes the binary interface, the Imager API version has
1261 been incremented. Any module that uses the API will need to be
1262 rebuilt. In most cases that will be enough, but calls to any APIs
1263 that take a pointer to image sizes may need source changes.
1264
1265 - you should be able to create very large images on 64-bit systems,
1266 if you have enough memory. Successfully created a 32768 x 49192 x
1267 3 channel image, filled with a tiled image and scaled it. The
1268 unscaled image was also successfully saved to a JPEG.
1269
1270 - check the image size before attempting to write BMP, GIF, JPEG,
1271 PNG, SGI, TGA, TIFF images.
1272
1273 - correctly handle reading TGA images over 32767 pixels wide or tall.
1274
1275Incidental changes:
1276
1277 - the gif_left and gif_top tags are now clamped to non-negative
1278 values when writing a GIF image.
1279
1280 - removed dead callback read/write code
1281
1282The default maximum memory size when reading files is now 1G.

1929 - moved the imtoc.perl code into Imager::Preprocess

1934 noalpha channels or back.
1935 https://rt.cpan.org/Ticket/Display.html?id=30908
1936
1937 - rubthrough() now falls back to pasting when the source doesn't have
1938 an alpha channel. This effectively treats the source as having a
1939 max alpha channel, the right thing to do.
1940 http://rt.cpan.org/Ticket/Display.html?id=29944
1941
1942 - re-worked most of the area filling code to use a common set of

1945 Rewrote most of the combine modes to match the way the SVG draft
1946 defines them with respect to a translucent source and destination.
1947 Added tests for translucent source and destination.

1949 similarly.

1990 being set was treated as an opaque pixel, but one user reported a
1991 problem with loading such an image. I haven't been able to find any
1992 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1993 I'll match it's behaviour. See issue 114913 in the GIMP's
1994 bugzilla.

2160 indexes outside the range of colors defined by the image's palette.
2161 We now expand the palette to match the indexes used.
2162 Thanks to Gabriel Vasseur for reporting this.

2167 - to avoid confusion, channels not present in the image are returned as
2168 zero by getscanline(). This has no effect on the C level i_glin()

2170 channels.

2312Imager 0.55 - 16 Dec 2006
2313===========
2314
2315This is primarily a bug fix release.
2316
2317Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2318
2319There is one new feature:
2320
2321 - the Win32 font driver now supports UTF8 (RT 22166)
2322 http://www.cpanforum.com/threads/3276
2323 http://rt.cpan.org/Ticket/Display.html?id=22166
2324
2325Several bugs were fixed:
2326
2327 - the string() method would not output the string "0"
2328 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2329
2330 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2331 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2332
2333 - the gif_disposal and gif_user_input tags weren't being read from
2334 the file correctly
2335 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2336
2337 - gif.c was failing to build under MSVC
2338 http://rt.cpan.org/Ticket/Display.html?id=23922
2339
2340 - in some cases strings passed to the string() method were treated as
2341 terminated by NUL (chr 0)
2342 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2343
2344 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2345 that's the default build name for zlib on Win32.
2346 http://rt.cpan.org/Ticket/Display.html?id=23064
2347
2348 - search $Config{incpath} for headers too, which we should have been
2349 doing all along.
2350
2351Win32 font driver fixes:
2352
2353 - the global descent value from bounding box was the wrong sign
2354 http://www.cpanforum.com/threads/3276
2355
2356 - if the first or last glyph overflowed the left or right side of the
2357 advance width they would be clipped
2358
2359
2360Imager 0.54 - 14 Sep 2006
2361===========
2362
2363This is primarily a feature release:
2364
2365 - a new qtype value 'mixing' has been added to the scale()
2366 method. This is faster than 'normal', slower than 'preview'. This
2367 is based on the method used by pnmscale, and seems to produce less
2368 blurry results than normal.
2369 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2370
2371 - the rubthrough() method can now render onto images with an alpha
2372 channel.
2373 http://rt.cpan.org/Ticket/Display.html?id=20678
2374
2375 - the read_multi() method now falls back to calling doing a single
2376 image read via the read() method and write_multi() will now fall
2377 back to calling write() if a single image is supplied. This means
2378 you can simply call the read_multi() or write_multi() functions
2379 without having to check if the type is formatted by that method.
2380 http://rt.cpan.org/Ticket/Display.html?id=19457
2381 http://rt.cpan.org/Ticket/Display.html?id=19458
2382
2383 - the GIF loop extension can now be written. If you don't have
2384 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2385 should upgrade.
2386 http://rt.cpan.org/Ticket/Display.html?id=21185
2387
2388 - getscanline() and setscanline() can now read/write palette index
2389 based data from/to the image for paletted images, by setting type to
2390 'index'.
2391 http://rt.cpan.org/Ticket/Display.html?id=20338
2392
2393 - we no longer hassle you to disable GIF support
2394 http://rt.cpan.org/Ticket/Display.html?id=20687
2395
2396 - minor documentation fixes
2397
2398
2399Imager 0.53 - 26 Jul 2006
2400===========
2401
2402This is a bugfix release.
2403
2404Some test code was left in a code path not covered by the test
2405suite. A test was added to cover this code path and the test code was
2406removed.

2409
2410Imager 0.52 - 25 Jul 2006
2411===========
2412
2413This is primarily a feature release, but contains a fair few bug
2414fixes, new features:
2415
2416 - ability to read and write MS Windows ICO and CUR files
2417
2418 - you can now add file format plugins to support new file formats
2419
2420 - add POD coverage tests
2421
2422 - setcolors() and addcolors() now accept color names and so on
2423 instead of requiring Imager::Color objects.
2424 http://rt.cpan.org/Ticket/Display.html?id=20056
2425
2426 - flood_fill() can now fill to a specified border color instead of
2427 just to the area the same color as the seed.
2428 http://rt.cpan.org/Ticket/Display.html?id=19618
2429
2430
2431Bug fixes:
2432
2433 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2434 calculating the advance width.
2435 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2436
2437 - bounding_box for the T1 driver wasn't including leading and
2438 trailing spaces in the bounding box as the other drivers did, it also
2439 produced strange results for empty strings or strings containing only
2440 spaces
2441
2442 - when reading CMYK jpeg images they were being transferred to the
2443 image object as is, producing a four channel image. It only looked ok
2444 due to an old still unfixed Photoshop bug. We now convert from the
2445 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2446 http://rt.cpan.org/Ticket/Display.html?id=20416
2447
2448 - reading a CYMK TIFF would result in a 4 channel image, reading any
2449 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2450 result in an error.
2451 http://rt.cpan.org/Ticket/Display.html?id=20415
2452
2453 - added /usr/local/include to the default include search path, since
2454 we were already searching /usr/local/lib for libraries.
2455
2456And various minor fixes and documentation updates.
2457
2458
2459Imager 0.51 - 23 Apr 2006

2463 a crash

2465

2480 output is an in-memeory buffer.
