2
c443788c
TC
3 - Imager is moving to github.
4
5 - T1lib support is deprecated
6
7 - added guassian2 filter which allows separate filter radii for vertical
8 and horizontal. Thanks to Leolo.
9 https://rt.cpan.org/Ticket/Display.html?id=129769
10
11 - freetype2 support can now use pkg-config to configure itself.

13Imager 1.011 - 7 Mar 2019
14============
15
7e5c22f6
TC
16General changes:
17
18 - correct the type of the data parameter for im_decode_exif().
19
20 - fix the release date listed below for 1.010
21
22 - add missing change entry for RT #128142
23
e2f7e242
TC
24 - binmode the correct handle in t/200-file/010-iolayer.t, this may fix some test
25 failures on one CPAN smoker.
26
27 - add the mymeta check (AUTHOR testing only) to MANIFEST
28
29More Coverity fixes:
30
31 - translate_errdiff() could leak memory on failure (introduced in
32 1.009) CID 185565.
33
34 - i_img_make_palette() could leak memory on failure (introduced in
35 1.009) CID 185566.
36
37 - DSO_open(), from the original dynamic loading API, could leak
38 dlopen() handles on failure. CID 185309. DSO_close() now releases
39 the memory associated with the internal DSO handle, rather than
40 only releasing the dlopen() handle.
41
a84eb3ac 42Imager 1.010 - 13 Feb 2019
5497656d
TC
43============
44
45General changes:
46
47 - added the add_file_magic() class method for adding magic for new
48 file types to Imager's fairly primitive file magic detection.
49
50 - fixed an embarassing documentation typo in Imager::Test.
51
52 - trying to read from a GIF file with no images now sets an error
53 message. Thanks to Peter Sergeant for reporting this.
54 https://rt.cpan.org/Ticket/Display.html?id=128481
55
4321405f
TC
56 - use undeprecated encoding symbols for FT2. This should fix the
57 build on the badly patched CentOS 7 Freetype 2. Thanks to Slaven
58 Rezic for the report.
59 https://rt.cpan.org/Ticket/Display.html?id=128142
60
5497656d
TC
61Coverity has come back up read-only, a few more changes:
62
63 - add missing va_end() for bmp.c's write_packed(). CID 185320.
64
65 - similarly for read_packed(). CID 185329.
66
67 - add a NOTREACHED lint comment for pixel_coverage(). Compilers
68 complained about a missing return, Coverity complains about the
69 return. CID 185325.
70
71 - avoid a possible sign extension in imsgi.c. CID 185326.
72
73 - add some FALLTHROUGH lint comments to i_readtga_wiol() where we
74 deliberately fall through switch cases. CID 185328.
75
76 - add assertions in callers to i_new_hatch_low() since Coverity
77 complained about some possible inconsistent NULL checks. CID
78 185339. I ended up rearranging this function later.
79
80 - remove pointless NULL checks from i_flipxy() and i_img_destroy().
81

57cc9afe
TC
84============
85
1456b645
TC
86Critical issue:
87
88 - drawing a filled, anti-aliased circle to the left or right of the
89 image (not within the image at all) would cause a buffer overflow.
90 https://rt.cpan.org/Ticket/Display.html?id=128208
91
a3b721bb
TC
92General changes:
93
94 - to_paletted() and make_palette() now fail (with an error in
95 errstr()) if invalid quantization parameters are supplied.
96
35ec3a87
TC
97 - map() would corrupt a channel if there was a gap in the arrayref of
98 channels. Detected by Coverity. CID 185300.
99
5824f4c2
TC
100 - most numeric parameters to the XS implementation now throw an
101 exception if supplied an unoverloaded reference.
102 https://rt.cpan.org/Ticket/Display.html?id=128208
103
e32d3a7c
TC
104Coverity finally finished a build[1], fixed several of the problems
105found. Coverity went down before I could finish working through them.
1791cbdb 106
8445279e
TC
107High severity:
108
1791cbdb 109 - reading a color-mapped TGA file with an id string would cause a
8445279e 110 double-free if the palette was truncated. CID 185317.
1791cbdb 111
6494c395
TC
112 - mixing scaling to sizes where the accumulator row, the working
113 output row or the working input row didn't fit into the address
114 space could result in memory leaks. This can probably only be
8445279e 115 reproduced on very wide floating-point sample images. CID 185318.
6494c395 116
fc24ca5f 117 - convert an array style function parameter pointer to pointer style
3d7b055c 118 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 119 CID 185343.
3d7b055c 120
8445279e 121 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 122
20c297d4 123 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 124 implementation. CID 185303.
20c297d4 125
fc24ca5f 126 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 127 drawing (it should always end up being set.) CID 185341.
fc24ca5f 128
f7675b46 129 - addi style makemap could potentially read one past the end of an
8445279e 130 array. CID 185337.
f7675b46 131
58ec1fde
TC
132 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
133 would result in read beyond the end of the built-in hatch array.
134 Negative values (which Coverity didn't complain about) could also
8445279e 135 cause problems. CID 185331.
58ec1fde 136
b7346865
TC
137 - the Imager::Color set_internal() interal method no longer
138 calls the over-complicated ICL_set_internal() (which is retained
139 only for the old API.) Coverity complained that this leaked, but
140 this could only occur with an invalid (NULL pointer) color object.
8445279e 141 CID 185323.
b7346865 142
785364c1
TC
143 - the underlying implementation of the map() method could read before
144 the beginning on an allocated array if supplied with inconsistent
145 parameters, which Coverity complained about. No Imager code calls
146 that function with inconsistent parameters, but a
8445279e 147 belt-and-suspenders check was added. CID 185315.
785364c1 148
eb7e48c9
TC
149 - Coverity complained a call to i_getcolors(), used by the
150 implementation of the is_bilevel() method could leave the fetched
8445279e 151 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 152
c1c8b1e9
TC
153 - a numeric combining mode of 13 (eg. as a parameter to
154 Imager::Fill->new())could cause an invalid array read in
155 i_get_combine() due to a fencepost error in validating the combine
8445279e 156 number. CID 185299.
c1c8b1e9 157
59fd0c6b 158Lower severity (according to Coverity):
c4fd43be
TC
159
160 - avoid an unneeded EXTEND() call when the FT1 has_chars()
161 implementation returns 0. CID 185350.
162
163 - avoid accessing a possibly NULL map from MakeMapObject() in a
164 logging call. (GIF) CID 185296.
165
4615ad8d
TC
166 - gradgen() allocated the wrong amount of space (always too much) for
167 the color array. CID 185291.
168
ea3099db
TC
169 - avoid dead code in i_tt_glyph_names(). CID 185321.
170
8b810590
TC
171 - avoid dead code in i_get_anonymous_color_histo(), which is the
172 implementation of getcolorusage(). CID 185327.
173
4eb9a521
TC
174 - avoid dead code in i_ft2_glyph_name(), which is the implementation
175 of glyph_names() for FT2. CID 185342.
176
c028aa12
TC
177 - avoid dead code in i_t1_glyph_names(), which is the implementation
178 of glyph_names() for T1. CID 185322.
179
e7772cea
TC
180 - avoid an unneeded EXTEND() call when the FT2 has_chars()
181 implementation returns 0. CID 185292.
182
596f3eee
TC
183 - the unpack code for ICO/CUR file handling could extend 32-bit
184 unsigned values to 64-bit signed. I believe this is harmless. CID
185 185319.
186
a2ca2b80
TC
187 - remove an unneeded check when terminating the stream for JPEG
188 writing. CID 185347.
189
56ce7446
TC
190 - skip an unneeded check when freeing the combine temp buffer in the
191 fountain filter. CID 185286.
192
193 - check the combine function pointer consistently rather than the
194 combine code in one place in the fountain filter.
195
a3b721bb
TC
196 - error diffusion now validates a custom error diffusion map and reports
197 an error if it's bad. CID 185288.
198
215d9ead
TC
199 - avoid discarding the value of i_io_getc() when scanning numbers in
200 pnm.c. CID 185293.
201
9ca939d0
TC
202 - handle failure to clone the log filehandle when cloning the Imager
203 context object on thread creation. CID 185294.
204
70501294 205 - fix an unsigned comparison when converting character code to a
59fd0c6b
TC
206 glyph index with a NULL character map when calculating the glyph
207 for display for FT1. This should be rare. CID 185297.
208
209 - fix a similar bug when calculating whether a glyph is present for
210 has_chars() for FT1. CID 185302.
70501294 211
6fa51f9c
TC
212 - i_img_info() (C API) no longer tries to handle a NULL image object
213 pointer. CID 185298.
214
a2c2d400
TC
215 - re-work testing for size_t overflow for circle/random
216 super-sampling for fountain fills. CID 185304.
217
8e2e2347
TC
218 - don't check if the unsigned size passed to Imager's malloc wrapper
219 (mymalloc) is negative. Left from when that parameter was signed.
220 CID 185305.
221
0c16f204
TC
222 - make some types larger and add a cast to prevent integer overflows
223 when calculating a palette with median cut for extraordinarily
224 large images. CID 185306.
225
748bfdfc
TC
226 - don't check if the unsigned size supplied to
227 im_set_image_file_limits() is negative. CID 185307.
228
57cc9afe 229[1] The first two build submissions ended up at the end of a ~400 item
a3b721bb
TC
230build queue, and seemed to have been cancelled by Coverity. A build
231submitted on NYE went through in minutes.

TC
233Imager 1.008 - 31 Dec 2018
234============
235
75e155e1 236 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
237 This allows file formats that store EXIF data as blobs similarly
238 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 239
b5bbf161 240 - added some more file extensions to image file type mappings
75e155e1
TC
241
242 - added add_type_extensions() class method
243
f38e738a
TC
244 - Imager::Files now links to Imager::Install when discussing
245 appropriate libraries.

TC
249============
250
a9fa5463
TC
251 - add png_compression_level tag for writing PNG files.
252
253 - avoid flooring a second time in matrix transform interpolation.
254 https://rt.cpan.org/Ticket/Display.html?id=124001
255
434c2338
TC
256 - produce v2 metadata.
257 Includes change from the ticket and updates to sub-modules.

259
d1d8320e
TC
260 - improve error reporting for the polygon() method
261
ac3e79fb
TC
262Imager 1.006 - 26 Aug 2017
263============
264
ba7ddbae
TC
265 - the internal i_errors() function now correctly allocates the stack
266 space needed for its result.
267 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
268
269 - t/100-base/020-color.t now uses Imager::Test's test functions
270 instead of its own.
271 https://rt.cpan.org/Ticket/Display.html?id=111993
272
344dda51
TC
273 - write_multi() now returns an error result (a false value) if called
274 with a non-(Imager image object). Previously it would typically
275 crash.
276 https://rt.cpan.org/Ticket/Display.html?id=117878
277
278 - improve the documentation of the jpegquality parameter when
279 writing JPEG files.
280
281 - add code to mitigate CVE-2016-1238, Imager will no longer search the
282 default current directory entry in @INC when searching for file
283 format support modules.

285Imager 1.005 - 16 Apr 2016
286============
287
288It's now been ten years since I switched to the new Changes file in
289release 0.55.
290
cd0109d8
TC
291 - revert the ivdformat probes, they don't work as is and trying to
292 fix them is too much work for now.
293
6f1cbfed
TC
294Imager 1.004_004 - 15 Apr 2016
295================
296
9c45cc49
TC
297 - test that the ivdformat from Config is correct and look for a valid
298 one if it isn't.
299 For the strange Win32 failures.
300
301 - fix a copy and paste error in pod in samples/samp-form.cgi
302
5cea6ea1
TC
303Imager 1.004_003 - 23 Mar 2016
304================
305
bd2d657d
TC
306 - add some extra error reporting to the I/O layers tests, this might
307 help catch a failure seen on Win32.

TC
310Imager 1.004_002 - 20 Mar 2016
311================
312
735b3e7b
TC
313 - don't use the seek() method on opened() handles in
314 t/200-file/400-basic.t. In older versions of perl such handles are
315 only IO::Handle objects, not IO::File, and don't have a seek()
316 method.
317

TC
318Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
319================
320
08914ed1
TC
321 - re-work the t/200-file/400-basic.t to correctly handle failures
322 It's custom ok() function didn't have a prototype and didn't use scalar().
323 This caused ok() to use the note instead of the value being tested when
324 the method called returned an empty list. For an example of the problem
e6226ce5 325 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 326
a2791e47
TC
327 - remove some noise from when Imager tried to work with bugs in old
328 versions of giflib. I can't do much about the new bugs.
08914ed1 329
e6226ce5
TC
330 - the new autolevels filter (Imager 0.99) used an integer for the
331 sample scaling factor which caused the top output level to be too
332 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
333 https://rt.cpan.org/Ticket/Display.html?id=111871
334
e6226ce5 335 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
336 minimum and maximum luminance from the histogram. This slightly
337 reduced the contrast of the output image.
338 https://rt.cpan.org/Ticket/Display.html?id=111871
339
340 - the new autolevels filter now uses a lookup table for 8-bit images
341 to avoid a floating point multiply for each sample.
342 https://rt.cpan.org/Ticket/Display.html?id=111871
343
e6226ce5
TC
344 - fixed several memory leaks detected by valgrind:
345
346 - addcolors() leaked the temporary array of colors supplied to the
347 internal API
348
349 - make_palette() leaked the temporary image array (not the images
350 themselves) passed to the internal API.
351
352 - combine()/i_combine() leaked its working row buffers
353
354 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
355 buffer if there were too many colors
356
357 - getcolorcount()/i_count_colors() leaked the sample buffer if
358 there were too many colors.
359
360 - the nearest_color filter (undocumented until I find a use for it)
361 leaked both temporaries passed to the API and internal buffers
362
a2791e47
TC
363 - the internal process of upgrading a paletted image to a direct
364 color image would leak a context object reference count.
365
366 - a write failure when writing to a GIF file could leak memory.
367
368 - failing to write to a 1-bit/pixel ICO image could leak memory.
369
370 - Imager no longer deliberately leaks the context object from the
371 initial thread. This was done to ensure there was always a context
372 object available, but the code that needed that now handles the
373 lack correctly,
374
e6226ce5
TC
375 - fixed some uninitialized memory usage detected by valgrind:
376
377 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
378 i_matrix_transform_bg() didn't initialize a working color value
379 if there was zero pixel coverage.
380
381 - i_ft2_cp() didn't initialize the complete color when producing an
382 intermediate image. This caused uninitialized value usage when
383 logging the color.

TC
385Imager 1.004 - 8 Nov 2015
386============
387
5ebfb369
TC
388 - Imager::Color::Table is now pre-loaded by the preload() method.
389 https://rt.cpan.org/Ticket/Display.html?id=104896
390
391 - fix an assertion triggered under perl 5.23.4.
392 Thanks to A. Sinan Unur for the report and the patch.
393
7b638aba
TC
394 - Imager->new can now be used to read raw image files.
395 https://rt.cpan.org/Ticket/Display.html?id=106836
f7160b21 396 Thanks to Richard Kelsch for reporting this.
7b638aba
TC
397
398 - deal with output changes from Pod::Spell

0d1baac8
TC
401Imager 1.003 - 12 May 2015
402============
403
0fda3cfd
TC
404 - update 1.002 release notes to include the center change for filled
405 circle drawing.
406
407 - flood_fill() would escape beyond a 4-connected space under some
408 circumstances.
409 Added many more flood_fill() tests.

411
647a47c9
TC
412Imager 1.002 - 3 Apr 2015
413============
414
334b8922
TC
415 - drawing anti-aliased filled circles is now 10 to 50 times faster
416 depending on the size of the circle.
0fda3cfd
TC
417 This also changed the center from being the center of the pixel to
418 being the top left of the pixel to match the filled arcs drawn by
419 arc().
334b8922
TC
420 https://rt.cpan.org/Ticket/Display.html?id=101682
421
422 - enhancements to polygon filling:
423
424 - added a mode parameter to control how overlapping regions behave
425
426 - added a polypolygon() method to fill more than one polygon at a
427 time
428
429 - polygon filling is now exposed through the API.
430
45c8e262
TC
431 - added colormodel(), alphachannel() and colorchannels() methods.
432 These were added for two reasons:
433
434 - a future version of Imager may allow the number of channels in
435 an image to not directly represent the color model of an image.
436 eg. a greyscale TIFF image with multiple alpha channels.
437
438 - a future version of Imager may allow an image to be read without
439 translation, for example a TIFF file that contains measurements
0fda3cfd 440 from an instrument. Currently Imager transforms the samples into
d96c4de8 441 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
442 the value back.
443
444 An untranslated image would be unusable as image data, so
445 colormodel() would return "unknown" in this case.

555 - Imager::File::PNG now supports libpng 1.6.10.
556 1.6.10 changed CRC errors from benign errors to normal errors,
557 which broke the test which used CRC errors to check for benign
558 error support. Switched to using a 1-bit grey-scale image with a
559 palette to test for benign errors.

563===========
564
f84f86a2
TC
565Incompatible changes:
566
567 - the return value of setpixel() has changed.
568
569 Previously the return values for undrawable pixels vs caller errors
570 changed depending on whether you used the multiple pixel calling
571 mechanism, or the single pixel mechanism.
572
573 Now:
574
575 - for an invalid parameter, such as an unknown colour, or missing
576 parameter, an empty list (or undef in scalar context) is
577 returned, and errstr() is set,
578
579 - otherwise the number of pixels drawn is returned. If none of
580 the pixels could be drawn (they were all outside the image), "0
581 but true" is returned.
582
583 https://rt.cpan.org/Ticket/Display.html?id=87650
584
585Other changes:
586
6ba09ab9
TC
587 - when drawing on an image with an alpha channel where the source
588 minimum is greater than zero, Imager would read from beyond the end
589 of a malloc() allocated buffer. In rare circumstances this could
590 lead to some of the source image not being written to the target
591 image, or possibly to a segmentation fault.
592 I don't believe this has any security concerns beyond that.
593
0d052fd9
TC
594 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
595 text drawn would be nonsense. This would also read beyond the end
596 of a malloced buffer.
597
13671b17
TC
598 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
599 truncated early.

645 SampleFormat is ignored for paletted images.
646
237d9e03
TC
647 Mixed SampleFormat are handled incorrectly, since libtiff returns
648 only the first SampleFormat value, and an image with both an alpha
649 channel and SampleFormat = 2 for color channels probably has a
650 different SampleFormat for the alpha channel.

899 - The size of rotated images is no longer rounded up so aggressively.
900 Added rounding to the linear interpolation done for rotate() and
901 matrix_transform() for 1 and 3 channel 8-bit images.
902 Adjusted the two tranlate matrices used to build the final rotation
903 matrix to use the distance between the outlier pixels rather than
904 the pixel dimensions (ie. dimension-1).
905 With all of this the output of rotate(degrees => 270) on an 8-bit
906 image exactly matches the output of rotate(right => 270).

914 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
915 the API level compiled into a loadable module such as
916 Imager::File::GIF doesn't match that of Imager. Previously it

939 - when downconverting samples (eg. from floating point to 8 bit)
940 Imager now rounds the sample value rather than attempting to
941 allocate input values over output values equally. The old
942 behaviour had the probably surprising effect of converting a
943 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
944 2.
945 This may result in slightly different 8 or 16-bit output images.

1217 - io_glue I/O buffering re-work:
1218
1219 - reorganize io_glue to do it's own buffering by default
1220
1221 - the unbuffered functions are available as i_io_raw_read() (or
1222 raw_read() from perl) etc but are not recommended for typical
1223 use.
1224
1225 - use the new i_io_peekn() when checking for file magic to avoid
1226 seek, allowing Imager to detect the file type and read the file
1227 from an unseekable stream (for formats that don't use random
1228 access)

1237
1238 - the callback IO object did its own buffering, controlled by the
1239 maxbuffer parameter supplied to the read() and write() methods.
1240 This buffering has been removed, to avoid redundancy with the
1241 common io_glue buffering. This also avoids a bug in that code
1242 which could rarely pass a zero length to the read callback and
1243 then panic about the result.
1244
1245 - the callback IO object now tests the result of calling the close
1246 callback, which should return true for success.
1247
1248 - the PNM reader did its own buffering. This buffering has been
1249 removed to avoid redundancy with the common io_glue buffering.
1250
1251 - previously the read handlers for fd and callback I/O layers would
1252 call the underlying interface (POSIX read or your supplied callback)
1253 until it filled the buffer. It now only makes one call.
1254
1255 - added public constructors for I/O layer objects (see Imager::IO)
1256
1257 - all core file handlers now use the i_io_foo() wrappers to gain
1258 access to buffered I/O rather than calling the I/O layer
1259 callbacks directly.
1260
1261 - all core file handlers now check for error on close.
1262
1263 - Backward compatibility: if you hava custom file handlers, you can
1264 use i_io_write() etc since they're available as macros in older
1265 versions of Imager.
1266
1267 - eliminate the final remnants of io_glue_commit_types().
1268
1269 - bump IMAGER_API_VERSION, since the above may break assumptions.

1332Imager 0.84_01 - 8 Aug 2011
1333==============
1334
1335Development release as a sanity check for the types re-work.
8d14daab
TC
1336
1337Massive types re-work:
1338
1339 - the type used internally for pixel co-ordinates and image sizes is
1340 now 64-bit on 64-bit platforms (at least sane ones).
1341
1342 - size_t is now used consistently for memory block sizes.
1343
1344 - since this changes the binary interface, the Imager API version has
1345 been incremented. Any module that uses the API will need to be
1346 rebuilt. In most cases that will be enough, but calls to any APIs
1347 that take a pointer to image sizes may need source changes.
1348
1349 - you should be able to create very large images on 64-bit systems,
1350 if you have enough memory. Successfully created a 32768 x 49192 x
1351 3 channel image, filled with a tiled image and scaled it. The
1352 unscaled image was also successfully saved to a JPEG.
1353
1354 - check the image size before attempting to write BMP, GIF, JPEG,
1355 PNG, SGI, TGA, TIFF images.
1356
1357 - correctly handle reading TGA images over 32767 pixels wide or tall.
1358
1359Incidental changes:
1360
1361 - the gif_left and gif_top tags are now clamped to non-negative
1362 values when writing a GIF image.
1363
1364 - removed dead callback read/write code
1365
1366The default maximum memory size when reading files is now 1G.

2013 - moved the imtoc.perl code into Imager::Preprocess

2015 - paste() and rubthrough() now adapt the source image data to the

2018 noalpha channels or back.
2019 https://rt.cpan.org/Ticket/Display.html?id=30908
2020
2021 - rubthrough() now falls back to pasting when the source doesn't have
2022 an alpha channel. This effectively treats the source as having a
2023 max alpha channel, the right thing to do.
2024 http://rt.cpan.org/Ticket/Display.html?id=29944

2026 - re-worked most of the area filling code to use a common set of

2029 Rewrote most of the combine modes to match the way the SVG draft
2030 defines them with respect to a translucent source and destination.

2075 problem with loading such an image. I haven't been able to find any
2076 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
2077 I'll match it's behaviour. See issue 114913 in the GIMP's

2396Imager 0.55 - 16 Dec 2006
2397===========
2398
2399This is primarily a bug fix release.
2400
2401Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2402
2403There is one new feature:
2404
2405 - the Win32 font driver now supports UTF8 (RT 22166)
2406 http://www.cpanforum.com/threads/3276
2407 http://rt.cpan.org/Ticket/Display.html?id=22166
2408
2409Several bugs were fixed:
2410
2411 - the string() method would not output the string "0"
2412 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2413
2414 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2415 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2416
2417 - the gif_disposal and gif_user_input tags weren't being read from
2418 the file correctly
2419 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2420
2421 - gif.c was failing to build under MSVC
2422 http://rt.cpan.org/Ticket/Display.html?id=23922
2423
2424 - in some cases strings passed to the string() method were treated as
2425 terminated by NUL (chr 0)
2426 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2427
2428 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2429 that's the default build name for zlib on Win32.
2430 http://rt.cpan.org/Ticket/Display.html?id=23064
2431
2432 - search $Config{incpath} for headers too, which we should have been
2433 doing all along.
2434
2435Win32 font driver fixes:
2436
2437 - the global descent value from bounding box was the wrong sign
2438 http://www.cpanforum.com/threads/3276
2439
2440 - if the first or last glyph overflowed the left or right side of the
2441 advance width they would be clipped
2442
2443
2444Imager 0.54 - 14 Sep 2006
2445===========
2446
2447This is primarily a feature release:
2448
2449 - a new qtype value 'mixing' has been added to the scale()
2450 method. This is faster than 'normal', slower than 'preview'. This
2451 is based on the method used by pnmscale, and seems to produce less
2452 blurry results than normal.
2453 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2454
2455 - the rubthrough() method can now render onto images with an alpha
2456 channel.
2457 http://rt.cpan.org/Ticket/Display.html?id=20678
2458
2459 - the read_multi() method now falls back to calling doing a single
2460 image read via the read() method and write_multi() will now fall
2461 back to calling write() if a single image is supplied. This means
2462 you can simply call the read_multi() or write_multi() functions
2463 without having to check if the type is formatted by that method.
2464 http://rt.cpan.org/Ticket/Display.html?id=19457
2465 http://rt.cpan.org/Ticket/Display.html?id=19458
2466
2467 - the GIF loop extension can now be written. If you don't have
2468 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2469 should upgrade.
2470 http://rt.cpan.org/Ticket/Display.html?id=21185
2471
2472 - getscanline() and setscanline() can now read/write palette index
2473 based data from/to the image for paletted images, by setting type to
2474 'index'.
2475 http://rt.cpan.org/Ticket/Display.html?id=20338
2476
2477 - we no longer hassle you to disable GIF support
2478 http://rt.cpan.org/Ticket/Display.html?id=20687
2479
2480 - minor documentation fixes
2481
2482
2483Imager 0.53 - 26 Jul 2006
2484===========
2485
2486This is a bugfix release.
2487
2488Some test code was left in a code path not covered by the test
2489suite. A test was added to cover this code path and the test code was
2490removed.

2493
2494Imager 0.52 - 25 Jul 2006
2495===========
2496
2497This is primarily a feature release, but contains a fair few bug
2498fixes, new features:
2499
2500 - ability to read and write MS Windows ICO and CUR files
2501
2502 - you can now add file format plugins to support new file formats
2503
2504 - add POD coverage tests
2505
2506 - setcolors() and addcolors() now accept color names and so on
2507 instead of requiring Imager::Color objects.
2508 http://rt.cpan.org/Ticket/Display.html?id=20056
2509
2510 - flood_fill() can now fill to a specified border color instead of
2511 just to the area the same color as the seed.
2512 http://rt.cpan.org/Ticket/Display.html?id=19618
2513
2514
2515Bug fixes:
2516
2517 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2518 calculating the advance width.
2519 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2520
2521 - bounding_box for the T1 driver wasn't including leading and
2522 trailing spaces in the bounding box as the other drivers did, it also
2523 produced strange results for empty strings or strings containing only
2524 spaces
2525
2526 - when reading CMYK jpeg images they were being transferred to the
2527 image object as is, producing a four channel image. It only looked ok
2528 due to an old still unfixed Photoshop bug. We now convert from the
2529 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2530 http://rt.cpan.org/Ticket/Display.html?id=20416
2531
2532 - reading a CYMK TIFF would result in a 4 channel image, reading any
2533 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2534 result in an error.
2535 http://rt.cpan.org/Ticket/Display.html?id=20415
2536
2537 - added /usr/local/include to the default include search path, since
2538 we were already searching /usr/local/lib for libraries.
2539
2540And various minor fixes and documentation updates.
2541
2542
2543Imager 0.51 - 23 Apr 2006

2564 output is an in-memeory buffer.
