3Imager 1.011 - 7 Mar 2019
4============
5
7e5c22f6
TC
6General changes:
7
8 - correct the type of the data parameter for im_decode_exif().
9
10 - fix the release date listed below for 1.010
11
12 - add missing change entry for RT #128142
13
e2f7e242
TC
14 - binmode the correct handle in t/200-file/010-iolayer.t, this may fix some test
15 failures on one CPAN smoker.
16
17 - add the mymeta check (AUTHOR testing only) to MANIFEST
18
19More Coverity fixes:
20
21 - translate_errdiff() could leak memory on failure (introduced in
22 1.009) CID 185565.
23
24 - i_img_make_palette() could leak memory on failure (introduced in
25 1.009) CID 185566.
26
27 - DSO_open(), from the original dynamic loading API, could leak
28 dlopen() handles on failure. CID 185309. DSO_close() now releases
29 the memory associated with the internal DSO handle, rather than
30 only releasing the dlopen() handle.
31
a84eb3ac 32Imager 1.010 - 13 Feb 2019
5497656d
TC
33============
34
35General changes:
36
37 - added the add_file_magic() class method for adding magic for new
38 file types to Imager's fairly primitive file magic detection.
39
40 - fixed an embarassing documentation typo in Imager::Test.
41
42 - trying to read from a GIF file with no images now sets an error
43 message. Thanks to Peter Sergeant for reporting this.
44 https://rt.cpan.org/Ticket/Display.html?id=128481
45
4321405f
TC
46 - use undeprecated encoding symbols for FT2. This should fix the
47 build on the badly patched CentOS 7 Freetype 2. Thanks to Slaven
48 Rezic for the report.
49 https://rt.cpan.org/Ticket/Display.html?id=128142
50
5497656d
TC
51Coverity has come back up read-only, a few more changes:
52
53 - add missing va_end() for bmp.c's write_packed(). CID 185320.
54
55 - similarly for read_packed(). CID 185329.
56
57 - add a NOTREACHED lint comment for pixel_coverage(). Compilers
58 complained about a missing return, Coverity complains about the
59 return. CID 185325.
60
61 - avoid a possible sign extension in imsgi.c. CID 185326.
62
63 - add some FALLTHROUGH lint comments to i_readtga_wiol() where we
64 deliberately fall through switch cases. CID 185328.
65
66 - add assertions in callers to i_new_hatch_low() since Coverity
67 complained about some possible inconsistent NULL checks. CID
68 185339. I ended up rearranging this function later.
69
70 - remove pointless NULL checks from i_flipxy() and i_img_destroy().

57cc9afe
TC
74============
75
1456b645
TC
76Critical issue:
77
78 - drawing a filled, anti-aliased circle to the left or right of the
79 image (not within the image at all) would cause a buffer overflow.
80 https://rt.cpan.org/Ticket/Display.html?id=128208
81
a3b721bb
TC
82General changes:
83
84 - to_paletted() and make_palette() now fail (with an error in
85 errstr()) if invalid quantization parameters are supplied.
86
35ec3a87
TC
87 - map() would corrupt a channel if there was a gap in the arrayref of
88 channels. Detected by Coverity. CID 185300.
89
5824f4c2
TC
90 - most numeric parameters to the XS implementation now throw an
91 exception if supplied an unoverloaded reference.
92 https://rt.cpan.org/Ticket/Display.html?id=128208
93
e32d3a7c
TC
94Coverity finally finished a build[1], fixed several of the problems
95found. Coverity went down before I could finish working through them.
1791cbdb 96
8445279e
TC
97High severity:
98
1791cbdb 99 - reading a color-mapped TGA file with an id string would cause a
8445279e 100 double-free if the palette was truncated. CID 185317.
1791cbdb 101
6494c395
TC
102 - mixing scaling to sizes where the accumulator row, the working
103 output row or the working input row didn't fit into the address
104 space could result in memory leaks. This can probably only be
8445279e 105 reproduced on very wide floating-point sample images. CID 185318.
6494c395 106
fc24ca5f 107 - convert an array style function parameter pointer to pointer style
3d7b055c 108 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 109 CID 185343.
3d7b055c 110
8445279e 111 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 112
20c297d4 113 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 114 implementation. CID 185303.
20c297d4 115
fc24ca5f 116 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 117 drawing (it should always end up being set.) CID 185341.
fc24ca5f 118
f7675b46 119 - addi style makemap could potentially read one past the end of an
8445279e 120 array. CID 185337.
f7675b46 121
58ec1fde
TC
122 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
123 would result in read beyond the end of the built-in hatch array.
124 Negative values (which Coverity didn't complain about) could also
8445279e 125 cause problems. CID 185331.
58ec1fde 126
b7346865
TC
127 - the Imager::Color set_internal() interal method no longer
128 calls the over-complicated ICL_set_internal() (which is retained
129 only for the old API.) Coverity complained that this leaked, but
130 this could only occur with an invalid (NULL pointer) color object.
8445279e 131 CID 185323.
b7346865 132
785364c1
TC
133 - the underlying implementation of the map() method could read before
134 the beginning on an allocated array if supplied with inconsistent
135 parameters, which Coverity complained about. No Imager code calls
136 that function with inconsistent parameters, but a
8445279e 137 belt-and-suspenders check was added. CID 185315.
785364c1 138
eb7e48c9
TC
139 - Coverity complained a call to i_getcolors(), used by the
140 implementation of the is_bilevel() method could leave the fetched
8445279e 141 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 142
c1c8b1e9
TC
143 - a numeric combining mode of 13 (eg. as a parameter to
144 Imager::Fill->new())could cause an invalid array read in
145 i_get_combine() due to a fencepost error in validating the combine
8445279e 146 number. CID 185299.
c1c8b1e9 147
59fd0c6b 148Lower severity (according to Coverity):
c4fd43be
TC
149
150 - avoid an unneeded EXTEND() call when the FT1 has_chars()
151 implementation returns 0. CID 185350.
152
153 - avoid accessing a possibly NULL map from MakeMapObject() in a
154 logging call. (GIF) CID 185296.
155
4615ad8d
TC
156 - gradgen() allocated the wrong amount of space (always too much) for
157 the color array. CID 185291.
158
ea3099db
TC
159 - avoid dead code in i_tt_glyph_names(). CID 185321.
160
8b810590
TC
161 - avoid dead code in i_get_anonymous_color_histo(), which is the
162 implementation of getcolorusage(). CID 185327.
163
4eb9a521
TC
164 - avoid dead code in i_ft2_glyph_name(), which is the implementation
165 of glyph_names() for FT2. CID 185342.
166
c028aa12
TC
167 - avoid dead code in i_t1_glyph_names(), which is the implementation
168 of glyph_names() for T1. CID 185322.
169
e7772cea
TC
170 - avoid an unneeded EXTEND() call when the FT2 has_chars()
171 implementation returns 0. CID 185292.
172
596f3eee
TC
173 - the unpack code for ICO/CUR file handling could extend 32-bit
174 unsigned values to 64-bit signed. I believe this is harmless. CID
175 185319.
176
a2ca2b80
TC
177 - remove an unneeded check when terminating the stream for JPEG
178 writing. CID 185347.
179
56ce7446
TC
180 - skip an unneeded check when freeing the combine temp buffer in the
181 fountain filter. CID 185286.
182
183 - check the combine function pointer consistently rather than the
184 combine code in one place in the fountain filter.
185
a3b721bb
TC
186 - error diffusion now validates a custom error diffusion map and reports
187 an error if it's bad. CID 185288.
188
215d9ead
TC
189 - avoid discarding the value of i_io_getc() when scanning numbers in
190 pnm.c. CID 185293.
191
9ca939d0
TC
192 - handle failure to clone the log filehandle when cloning the Imager
193 context object on thread creation. CID 185294.
194
70501294 195 - fix an unsigned comparison when converting character code to a
59fd0c6b
TC
196 glyph index with a NULL character map when calculating the glyph
197 for display for FT1. This should be rare. CID 185297.
198
199 - fix a similar bug when calculating whether a glyph is present for
200 has_chars() for FT1. CID 185302.
70501294 201
6fa51f9c
TC
202 - i_img_info() (C API) no longer tries to handle a NULL image object
203 pointer. CID 185298.
204
a2c2d400
TC
205 - re-work testing for size_t overflow for circle/random
206 super-sampling for fountain fills. CID 185304.
207
8e2e2347
TC
208 - don't check if the unsigned size passed to Imager's malloc wrapper
209 (mymalloc) is negative. Left from when that parameter was signed.
210 CID 185305.
211
0c16f204
TC
212 - make some types larger and add a cast to prevent integer overflows
213 when calculating a palette with median cut for extraordinarily
214 large images. CID 185306.
215
748bfdfc
TC
216 - don't check if the unsigned size supplied to
217 im_set_image_file_limits() is negative. CID 185307.
218
57cc9afe 219[1] The first two build submissions ended up at the end of a ~400 item
a3b721bb
TC
220build queue, and seemed to have been cancelled by Coverity. A build
221submitted on NYE went through in minutes.

b5bbf161
TC
223Imager 1.008 - 31 Dec 2018
224============
225
75e155e1 226 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
227 This allows file formats that store EXIF data as blobs similarly
228 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 229
b5bbf161 230 - added some more file extensions to image file type mappings
75e155e1
TC
231
232 - added add_type_extensions() class method
233
f38e738a
TC
234 - Imager::Files now links to Imager::Install when discussing
235 appropriate libraries.

237
b5bbf161 238Imager 1.007 - 24 Nov 2018
75e155e1
TC
239============
240
a9fa5463
TC
241 - add png_compression_level tag for writing PNG files.
242
243 - avoid flooring a second time in matrix transform interpolation.
244 https://rt.cpan.org/Ticket/Display.html?id=124001
245
434c2338
TC
246 - produce v2 metadata.
247 Includes change from the ticket and updates to sub-modules.
248 https://rt.cpan.org/Ticket/Display.html?id=127216
249
d1d8320e
TC
250 - improve error reporting for the polygon() method
251
ac3e79fb
TC
252Imager 1.006 - 26 Aug 2017
253============
254
ba7ddbae
TC
255 - the internal i_errors() function now correctly allocates the stack
256 space needed for its result.
257 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
258
259 - t/100-base/020-color.t now uses Imager::Test's test functions
260 instead of its own.
261 https://rt.cpan.org/Ticket/Display.html?id=111993
262
344dda51
TC
263 - write_multi() now returns an error result (a false value) if called
264 with a non-(Imager image object). Previously it would typically
265 crash.
266 https://rt.cpan.org/Ticket/Display.html?id=117878
267
268 - improve the documentation of the jpegquality parameter when
269 writing JPEG files.
270
271 - add code to mitigate CVE-2016-1238, Imager will no longer search the
272 default current directory entry in @INC when searching for file
273 format support modules.
274

TC
275Imager 1.005 - 16 Apr 2016
276============
277
278It's now been ten years since I switched to the new Changes file in
279release 0.55.
280
cd0109d8
TC
281 - revert the ivdformat probes, they don't work as is and trying to
282 fix them is too much work for now.
283
6f1cbfed
TC
284Imager 1.004_004 - 15 Apr 2016
285================
286
9c45cc49
TC
287 - test that the ivdformat from Config is correct and look for a valid
288 one if it isn't.
289 For the strange Win32 failures.
290
291 - fix a copy and paste error in pod in samples/samp-form.cgi
292
5cea6ea1
TC
293Imager 1.004_003 - 23 Mar 2016
294================
295
bd2d657d
TC
296 - add some extra error reporting to the I/O layers tests, this might
297 help catch a failure seen on Win32.

TC
300Imager 1.004_002 - 20 Mar 2016
301================
302
735b3e7b
TC
303 - don't use the seek() method on opened() handles in
304 t/200-file/400-basic.t. In older versions of perl such handles are
305 only IO::Handle objects, not IO::File, and don't have a seek()
306 method.
307
d47f1478
TC
308Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
309================
310
08914ed1
TC
311 - re-work the t/200-file/400-basic.t to correctly handle failures
312 It's custom ok() function didn't have a prototype and didn't use scalar().
313 This caused ok() to use the note instead of the value being tested when
314 the method called returned an empty list. For an example of the problem
e6226ce5 315 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 316
a2791e47
TC
317 - remove some noise from when Imager tried to work with bugs in old
318 versions of giflib. I can't do much about the new bugs.
08914ed1 319
e6226ce5
TC
320 - the new autolevels filter (Imager 0.99) used an integer for the
321 sample scaling factor which caused the top output level to be too
322 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
323 https://rt.cpan.org/Ticket/Display.html?id=111871
324
e6226ce5 325 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
326 minimum and maximum luminance from the histogram. This slightly
327 reduced the contrast of the output image.
328 https://rt.cpan.org/Ticket/Display.html?id=111871
329
330 - the new autolevels filter now uses a lookup table for 8-bit images
331 to avoid a floating point multiply for each sample.
332 https://rt.cpan.org/Ticket/Display.html?id=111871
333
e6226ce5
TC
334 - fixed several memory leaks detected by valgrind:
335
336 - addcolors() leaked the temporary array of colors supplied to the
337 internal API
338
339 - make_palette() leaked the temporary image array (not the images
340 themselves) passed to the internal API.
341
342 - combine()/i_combine() leaked its working row buffers
343
344 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
345 buffer if there were too many colors
346
347 - getcolorcount()/i_count_colors() leaked the sample buffer if
348 there were too many colors.
349
350 - the nearest_color filter (undocumented until I find a use for it)
351 leaked both temporaries passed to the API and internal buffers
352
a2791e47
TC
353 - the internal process of upgrading a paletted image to a direct
354 color image would leak a context object reference count.
355
356 - a write failure when writing to a GIF file could leak memory.
357
358 - failing to write to a 1-bit/pixel ICO image could leak memory.
359
360 - Imager no longer deliberately leaks the context object from the
361 initial thread. This was done to ensure there was always a context
362 object available, but the code that needed that now handles the
363 lack correctly,
364
e6226ce5
TC
365 - fixed some uninitialized memory usage detected by valgrind:
366
367 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
368 i_matrix_transform_bg() didn't initialize a working color value
369 if there was zero pixel coverage.
370
371 - i_ft2_cp() didn't initialize the complete color when producing an
372 intermediate image. This caused uninitialized value usage when
373 logging the color.

TC
375Imager 1.004 - 8 Nov 2015
376============
377
5ebfb369
TC
378 - Imager::Color::Table is now pre-loaded by the preload() method.
379 https://rt.cpan.org/Ticket/Display.html?id=104896
380
381 - fix an assertion triggered under perl 5.23.4.
382 Thanks to A. Sinan Unur for the report and the patch.
383
7b638aba
TC
384 - Imager->new can now be used to read raw image files.
385 https://rt.cpan.org/Ticket/Display.html?id=106836
f7160b21 386 Thanks to Richard Kelsch for reporting this.
7b638aba
TC
387
388 - deal with output changes from Pod::Spell

0d1baac8
TC
391Imager 1.003 - 12 May 2015
392============
393
0fda3cfd
TC
394 - update 1.002 release notes to include the center change for filled
395 circle drawing.
396
397 - flood_fill() would escape beyond a 4-connected space under some
398 circumstances.
399 Added many more flood_fill() tests.

TC
402Imager 1.002 - 3 Apr 2015
403============
404
334b8922
TC
405 - drawing anti-aliased filled circles is now 10 to 50 times faster
406 depending on the size of the circle.
0fda3cfd
TC
407 This also changed the center from being the center of the pixel to
408 being the top left of the pixel to match the filled arcs drawn by
409 arc().
334b8922
TC
410 https://rt.cpan.org/Ticket/Display.html?id=101682
411
412 - enhancements to polygon filling:
413
414 - added a mode parameter to control how overlapping regions behave
415
416 - added a polypolygon() method to fill more than one polygon at a
417 time
418
419 - polygon filling is now exposed through the API.
420
45c8e262
TC
421 - added colormodel(), alphachannel() and colorchannels() methods.
422 These were added for two reasons:
423
424 - a future version of Imager may allow the number of channels in
425 an image to not directly represent the color model of an image.
426 eg. a greyscale TIFF image with multiple alpha channels.
427
428 - a future version of Imager may allow an image to be read without
429 translation, for example a TIFF file that contains measurements
0fda3cfd 430 from an instrument. Currently Imager transforms the samples into
d96c4de8 431 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
432 the value back.
433
434 An untranslated image would be unusable as image data, so
435 colormodel() would return "unknown" in this case.
436
437 Similarly a CMYK image might be returned as an "unknown" color
438 model image, if the caller chooses to disable translation to
439 RGB.

441Imager 1.001 - 2 Jan 2015
442============
443
aca60e01
TC

546 1.6.10 changed CRC errors from benign errors to normal errors,
547 which broke the test which used CRC errors to check for benign
548 error support. Switched to using a 1-bit grey-scale image with a

553===========
554
f84f86a2
TC
555Incompatible changes:
556
557 - the return value of setpixel() has changed.
558
559 Previously the return values for undrawable pixels vs caller errors
560 changed depending on whether you used the multiple pixel calling
561 mechanism, or the single pixel mechanism.
562
563 Now:
564
565 - for an invalid parameter, such as an unknown colour, or missing
566 parameter, an empty list (or undef in scalar context) is
567 returned, and errstr() is set,
568
569 - otherwise the number of pixels drawn is returned. If none of
570 the pixels could be drawn (they were all outside the image), "0
571 but true" is returned.
572
573 https://rt.cpan.org/Ticket/Display.html?id=87650
574
575Other changes:
576
6ba09ab9
TC
577 - when drawing on an image with an alpha channel where the source
578 minimum is greater than zero, Imager would read from beyond the end
579 of a malloc() allocated buffer. In rare circumstances this could
580 lead to some of the source image not being written to the target
581 image, or possibly to a segmentation fault.
582 I don't believe this has any security concerns beyond that.
583
0d052fd9
TC
584 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
585 text drawn would be nonsense. This would also read beyond the end
586 of a malloced buffer.
587
13671b17
TC
588 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be

635 SampleFormat is ignored for paletted images.
636
237d9e03
TC
637 Mixed SampleFormat are handled incorrectly, since libtiff returns
638 only the first SampleFormat value, and an image with both an alpha
639 channel and SampleFormat = 2 for color channels probably has a
640 different SampleFormat for the alpha channel.

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

901 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
902 internals, those names only matter for the XS interface.

904 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
905 the API level compiled into a loadable module such as
906 Imager::File::GIF doesn't match that of Imager. Previously it
907 could be difficult to determine exactly which module was failing to

929 - when downconverting samples (eg. from floating point to 8 bit)
930 Imager now rounds the sample value rather than attempting to
931 allocate input values over output values equally. The old
932 behaviour had the probably surprising effect of converting a
933 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
934 2.
935 This may result in slightly different 8 or 16-bit output images.

937 - BI_BITFIELD BMP images were handled incorrectly, both in

1211 - the unbuffered functions are available as i_io_raw_read() (or
1212 raw_read() from perl) etc but are not recommended for typical
1213 use.
1214
1215 - use the new i_io_peekn() when checking for file magic to avoid
1216 seek, allowing Imager to detect the file type and read the file
1217 from an unseekable stream (for formats that don't use random
1218 access)

1228 - the callback IO object did its own buffering, controlled by the
1229 maxbuffer parameter supplied to the read() and write() methods.
1230 This buffering has been removed, to avoid redundancy with the
1231 common io_glue buffering. This also avoids a bug in that code
1232 which could rarely pass a zero length to the read callback and
1233 then panic about the result.
1234
1235 - the callback IO object now tests the result of calling the close
1236 callback, which should return true for success.
1237
1238 - the PNM reader did its own buffering. This buffering has been
1239 removed to avoid redundancy with the common io_glue buffering.
1240
1241 - previously the read handlers for fd and callback I/O layers would
1242 call the underlying interface (POSIX read or your supplied callback)
1243 until it filled the buffer. It now only makes one call.
1244
1245 - added public constructors for I/O layer objects (see Imager::IO)
1246
1247 - all core file handlers now use the i_io_foo() wrappers to gain
1248 access to buffered I/O rather than calling the I/O layer
1249 callbacks directly.
1250
1251 - all core file handlers now check for error on close.
1252
1253 - Backward compatibility: if you hava custom file handlers, you can
1254 use i_io_write() etc since they're available as macros in older
1255 versions of Imager.
1256
1257 - eliminate the final remnants of io_glue_commit_types().
1258
1259 - bump IMAGER_API_VERSION, since the above may break assumptions.

1322Imager 0.84_01 - 8 Aug 2011
1323==============
1324
1325Development release as a sanity check for the types re-work.
8d14daab
TC
1326
1327Massive types re-work:
1328
1329 - the type used internally for pixel co-ordinates and image sizes is
1330 now 64-bit on 64-bit platforms (at least sane ones).
1331
1332 - size_t is now used consistently for memory block sizes.
1333
1334 - since this changes the binary interface, the Imager API version has
1335 been incremented. Any module that uses the API will need to be
1336 rebuilt. In most cases that will be enough, but calls to any APIs
1337 that take a pointer to image sizes may need source changes.
1338
1339 - you should be able to create very large images on 64-bit systems,
1340 if you have enough memory. Successfully created a 32768 x 49192 x
1341 3 channel image, filled with a tiled image and scaled it. The
1342 unscaled image was also successfully saved to a JPEG.
1343
1344 - check the image size before attempting to write BMP, GIF, JPEG,
1345 PNG, SGI, TGA, TIFF images.
1346
1347 - correctly handle reading TGA images over 32767 pixels wide or tall.
1348
1349Incidental changes:
1350
1351 - the gif_left and gif_top tags are now clamped to non-negative
1352 values when writing a GIF image.
1353
1354 - removed dead callback read/write code
1355
1356The default maximum memory size when reading files is now 1G.

2003 - moved the imtoc.perl code into Imager::Preprocess

2008 noalpha channels or back.

2010
2011 - rubthrough() now falls back to pasting when the source doesn't have
2012 an alpha channel. This effectively treats the source as having a
2013 max alpha channel, the right thing to do.
2014 http://rt.cpan.org/Ticket/Display.html?id=29944

2019 Rewrote most of the combine modes to match the way the SVG draft
2020 defines them with respect to a translucent source and destination.

2065 problem with loading such an image. I haven't been able to find any
2066 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so

2386Imager 0.55 - 16 Dec 2006
2387===========
2388
2389This is primarily a bug fix release.
2390
2391Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2392
2393There is one new feature:
2394
2395 - the Win32 font driver now supports UTF8 (RT 22166)
2396 http://www.cpanforum.com/threads/3276
2397 http://rt.cpan.org/Ticket/Display.html?id=22166
2398
2399Several bugs were fixed:
2400
2401 - the string() method would not output the string "0"
2402 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2403
2404 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2405 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2406
2407 - the gif_disposal and gif_user_input tags weren't being read from
2408 the file correctly
2409 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2410
2411 - gif.c was failing to build under MSVC
2412 http://rt.cpan.org/Ticket/Display.html?id=23922
2413
2414 - in some cases strings passed to the string() method were treated as
2415 terminated by NUL (chr 0)
2416 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2417
2418 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2419 that's the default build name for zlib on Win32.
2420 http://rt.cpan.org/Ticket/Display.html?id=23064
2421
2422 - search $Config{incpath} for headers too, which we should have been
2423 doing all along.
2424
2425Win32 font driver fixes:
2426
2427 - the global descent value from bounding box was the wrong sign
2428 http://www.cpanforum.com/threads/3276
2429
2430 - if the first or last glyph overflowed the left or right side of the
2431 advance width they would be clipped
2432
2433
2434Imager 0.54 - 14 Sep 2006
2435===========
2436
2437This is primarily a feature release:
2438
2439 - a new qtype value 'mixing' has been added to the scale()
2440 method. This is faster than 'normal', slower than 'preview'. This
2441 is based on the method used by pnmscale, and seems to produce less
2442 blurry results than normal.
2443 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2444
2445 - the rubthrough() method can now render onto images with an alpha
2446 channel.
2447 http://rt.cpan.org/Ticket/Display.html?id=20678
2448
2449 - the read_multi() method now falls back to calling doing a single
2450 image read via the read() method and write_multi() will now fall
2451 back to calling write() if a single image is supplied. This means
2452 you can simply call the read_multi() or write_multi() functions
2453 without having to check if the type is formatted by that method.
2454 http://rt.cpan.org/Ticket/Display.html?id=19457
2455 http://rt.cpan.org/Ticket/Display.html?id=19458
2456
2457 - the GIF loop extension can now be written. If you don't have
2458 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2459 should upgrade.
2460 http://rt.cpan.org/Ticket/Display.html?id=21185
2461
2462 - getscanline() and setscanline() can now read/write palette index
2463 based data from/to the image for paletted images, by setting type to
2464 'index'.
2465 http://rt.cpan.org/Ticket/Display.html?id=20338
2466
2467 - we no longer hassle you to disable GIF support
2468 http://rt.cpan.org/Ticket/Display.html?id=20687
2469
2470 - minor documentation fixes
2471
2472
2473Imager 0.53 - 26 Jul 2006
2474===========
2475
2476This is a bugfix release.
2477
2478Some test code was left in a code path not covered by the test
2479suite. A test was added to cover this code path and the test code was
2480removed.

2483
2484Imager 0.52 - 25 Jul 2006
2485===========
2486
2487This is primarily a feature release, but contains a fair few bug
2488fixes, new features:
2489
2490 - ability to read and write MS Windows ICO and CUR files
2491
2492 - you can now add file format plugins to support new file formats
2493
2494 - add POD coverage tests
2495
2496 - setcolors() and addcolors() now accept color names and so on
2497 instead of requiring Imager::Color objects.
2498 http://rt.cpan.org/Ticket/Display.html?id=20056
2499
2500 - flood_fill() can now fill to a specified border color instead of
2501 just to the area the same color as the seed.
2502 http://rt.cpan.org/Ticket/Display.html?id=19618
2503
2504
2505Bug fixes:
2506
2507 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2508 calculating the advance width.
2509 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2510
2511 - bounding_box for the T1 driver wasn't including leading and
2512 trailing spaces in the bounding box as the other drivers did, it also
2513 produced strange results for empty strings or strings containing only
2514 spaces
2515
2516 - when reading CMYK jpeg images they were being transferred to the
2517 image object as is, producing a four channel image. It only looked ok
2518 due to an old still unfixed Photoshop bug. We now convert from the
2519 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2520 http://rt.cpan.org/Ticket/Display.html?id=20416
2521
2522 - reading a CYMK TIFF would result in a 4 channel image, reading any
2523 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2524 result in an error.
2525 http://rt.cpan.org/Ticket/Display.html?id=20415
2526
2527 - added /usr/local/include to the default include search path, since
2528 we were already searching /usr/local/lib for libraries.
2529
2530And various minor fixes and documentation updates.
2531
2532
2533Imager 0.51 - 23 Apr 2006
