18============
19
7e5c22f6
TC
20General changes:
21
22 - correct the type of the data parameter for im_decode_exif().
23
24 - fix the release date listed below for 1.010
25
26 - add missing change entry for RT #128142
27
e2f7e242
TC
28 - binmode the correct handle in t/200-file/010-iolayer.t, this may fix some test
29 failures on one CPAN smoker.
30
31 - add the mymeta check (AUTHOR testing only) to MANIFEST
32
33More Coverity fixes:
34
35 - translate_errdiff() could leak memory on failure (introduced in
36 1.009) CID 185565.
37
38 - i_img_make_palette() could leak memory on failure (introduced in
39 1.009) CID 185566.
40
41 - DSO_open(), from the original dynamic loading API, could leak
42 dlopen() handles on failure. CID 185309. DSO_close() now releases
43 the memory associated with the internal DSO handle, rather than
44 only releasing the dlopen() handle.

TC
47============
48
49General changes:
50
51 - added the add_file_magic() class method for adding magic for new
52 file types to Imager's fairly primitive file magic detection.
53
54 - fixed an embarassing documentation typo in Imager::Test.
55
56 - trying to read from a GIF file with no images now sets an error
57 message. Thanks to Peter Sergeant for reporting this.
58 https://rt.cpan.org/Ticket/Display.html?id=128481
59
4321405f
TC
60 - use undeprecated encoding symbols for FT2. This should fix the
61 build on the badly patched CentOS 7 Freetype 2. Thanks to Slaven
62 Rezic for the report.
63 https://rt.cpan.org/Ticket/Display.html?id=128142
64
5497656d
TC
65Coverity has come back up read-only, a few more changes:
66
67 - add missing va_end() for bmp.c's write_packed(). CID 185320.
68
69 - similarly for read_packed(). CID 185329.
70
71 - add a NOTREACHED lint comment for pixel_coverage(). Compilers
72 complained about a missing return, Coverity complains about the
73 return. CID 185325.
74
75 - avoid a possible sign extension in imsgi.c. CID 185326.
76
77 - add some FALLTHROUGH lint comments to i_readtga_wiol() where we
78 deliberately fall through switch cases. CID 185328.
79
80 - add assertions in callers to i_new_hatch_low() since Coverity
81 complained about some possible inconsistent NULL checks. CID
82 185339. I ended up rearranging this function later.
83
84 - remove pointless NULL checks from i_flipxy() and i_img_destroy().

1456b645
TC
90Critical issue:
91
92 - drawing a filled, anti-aliased circle to the left or right of the
93 image (not within the image at all) would cause a buffer overflow.
94 https://rt.cpan.org/Ticket/Display.html?id=128208
95
a3b721bb
TC
96General changes:
97
98 - to_paletted() and make_palette() now fail (with an error in
99 errstr()) if invalid quantization parameters are supplied.
100
35ec3a87
TC
101 - map() would corrupt a channel if there was a gap in the arrayref of
102 channels. Detected by Coverity. CID 185300.
103
5824f4c2
TC
104 - most numeric parameters to the XS implementation now throw an
105 exception if supplied an unoverloaded reference.
106 https://rt.cpan.org/Ticket/Display.html?id=128208
107
e32d3a7c
TC
108Coverity finally finished a build[1], fixed several of the problems
109found. Coverity went down before I could finish working through them.
1791cbdb 110
8445279e
TC
111High severity:
112
1791cbdb 113 - reading a color-mapped TGA file with an id string would cause a
8445279e 114 double-free if the palette was truncated. CID 185317.
1791cbdb 115
6494c395
TC
116 - mixing scaling to sizes where the accumulator row, the working
117 output row or the working input row didn't fit into the address
118 space could result in memory leaks. This can probably only be
8445279e 119 reproduced on very wide floating-point sample images. CID 185318.
6494c395 120
fc24ca5f 121 - convert an array style function parameter pointer to pointer style
3d7b055c 122 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 123 CID 185343.
3d7b055c 124
8445279e 125 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 126
20c297d4 127 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 128 implementation. CID 185303.
20c297d4 129
fc24ca5f 130 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 131 drawing (it should always end up being set.) CID 185341.
fc24ca5f 132
f7675b46 133 - addi style makemap could potentially read one past the end of an
8445279e 134 array. CID 185337.
f7675b46 135
58ec1fde
TC
136 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
137 would result in read beyond the end of the built-in hatch array.
138 Negative values (which Coverity didn't complain about) could also
8445279e 139 cause problems. CID 185331.
58ec1fde 140
b7346865
TC
141 - the Imager::Color set_internal() interal method no longer
142 calls the over-complicated ICL_set_internal() (which is retained
143 only for the old API.) Coverity complained that this leaked, but
144 this could only occur with an invalid (NULL pointer) color object.
8445279e 145 CID 185323.
b7346865 146
785364c1
TC
147 - the underlying implementation of the map() method could read before
148 the beginning on an allocated array if supplied with inconsistent
149 parameters, which Coverity complained about. No Imager code calls
150 that function with inconsistent parameters, but a
8445279e 151 belt-and-suspenders check was added. CID 185315.
785364c1 152
eb7e48c9
TC
153 - Coverity complained a call to i_getcolors(), used by the
154 implementation of the is_bilevel() method could leave the fetched
8445279e 155 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 156
c1c8b1e9
TC
157 - a numeric combining mode of 13 (eg. as a parameter to
158 Imager::Fill->new())could cause an invalid array read in
159 i_get_combine() due to a fencepost error in validating the combine
8445279e 160 number. CID 185299.
c1c8b1e9 161
59fd0c6b 162Lower severity (according to Coverity):
c4fd43be
TC
163
164 - avoid an unneeded EXTEND() call when the FT1 has_chars()
165 implementation returns 0. CID 185350.
166
167 - avoid accessing a possibly NULL map from MakeMapObject() in a
168 logging call. (GIF) CID 185296.
169
4615ad8d
TC
170 - gradgen() allocated the wrong amount of space (always too much) for
171 the color array. CID 185291.
172
ea3099db
TC
173 - avoid dead code in i_tt_glyph_names(). CID 185321.
174
8b810590
TC
175 - avoid dead code in i_get_anonymous_color_histo(), which is the
176 implementation of getcolorusage(). CID 185327.
177
4eb9a521
TC
178 - avoid dead code in i_ft2_glyph_name(), which is the implementation
179 of glyph_names() for FT2. CID 185342.
180
c028aa12
TC
181 - avoid dead code in i_t1_glyph_names(), which is the implementation
182 of glyph_names() for T1. CID 185322.
183
e7772cea
TC
184 - avoid an unneeded EXTEND() call when the FT2 has_chars()
185 implementation returns 0. CID 185292.
186
596f3eee
TC
187 - the unpack code for ICO/CUR file handling could extend 32-bit
188 unsigned values to 64-bit signed. I believe this is harmless. CID
189 185319.
190
a2ca2b80
TC
191 - remove an unneeded check when terminating the stream for JPEG
192 writing. CID 185347.
193
56ce7446
TC
194 - skip an unneeded check when freeing the combine temp buffer in the
195 fountain filter. CID 185286.
196
197 - check the combine function pointer consistently rather than the
198 combine code in one place in the fountain filter.
199
a3b721bb
TC
200 - error diffusion now validates a custom error diffusion map and reports
201 an error if it's bad. CID 185288.
202
215d9ead
TC
203 - avoid discarding the value of i_io_getc() when scanning numbers in
204 pnm.c. CID 185293.
205
9ca939d0
TC
206 - handle failure to clone the log filehandle when cloning the Imager
207 context object on thread creation. CID 185294.
208
70501294 209 - fix an unsigned comparison when converting character code to a
59fd0c6b
TC
210 glyph index with a NULL character map when calculating the glyph
211 for display for FT1. This should be rare. CID 185297.
212
213 - fix a similar bug when calculating whether a glyph is present for
214 has_chars() for FT1. CID 185302.
70501294 215
6fa51f9c
TC
216 - i_img_info() (C API) no longer tries to handle a NULL image object
217 pointer. CID 185298.
218
a2c2d400
TC
219 - re-work testing for size_t overflow for circle/random
220 super-sampling for fountain fills. CID 185304.
221
8e2e2347
TC
222 - don't check if the unsigned size passed to Imager's malloc wrapper
223 (mymalloc) is negative. Left from when that parameter was signed.
224 CID 185305.
225
0c16f204
TC
226 - make some types larger and add a cast to prevent integer overflows
227 when calculating a palette with median cut for extraordinarily
228 large images. CID 185306.
229
748bfdfc
TC
230 - don't check if the unsigned size supplied to
231 im_set_image_file_limits() is negative. CID 185307.
232
57cc9afe 233[1] The first two build submissions ended up at the end of a ~400 item
a3b721bb
TC
234build queue, and seemed to have been cancelled by Coverity. A build
235submitted on NYE went through in minutes.

TC
237Imager 1.008 - 31 Dec 2018
238============
239
75e155e1 240 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
241 This allows file formats that store EXIF data as blobs similarly
242 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 243
b5bbf161 244 - added some more file extensions to image file type mappings
75e155e1
TC
245
246 - added add_type_extensions() class method
247
f38e738a
TC
248 - Imager::Files now links to Imager::Install when discussing
249 appropriate libraries.

266Imager 1.006 - 26 Aug 2017
267============
268
ba7ddbae
TC
269 - the internal i_errors() function now correctly allocates the stack
270 space needed for its result.
271 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
272
273 - t/100-base/020-color.t now uses Imager::Test's test functions
274 instead of its own.
275 https://rt.cpan.org/Ticket/Display.html?id=111993
276
344dda51
TC
277 - write_multi() now returns an error result (a false value) if called
278 with a non-(Imager image object). Previously it would typically
279 crash.
280 https://rt.cpan.org/Ticket/Display.html?id=117878
281
282 - improve the documentation of the jpegquality parameter when
283 writing JPEG files.
284
285 - add code to mitigate CVE-2016-1238, Imager will no longer search the
286 default current directory entry in @INC when searching for file
287 format support modules.

294
cd0109d8

TC
298Imager 1.004_004 - 15 Apr 2016
299================
300
9c45cc49
TC
301 - test that the ivdformat from Config is correct and look for a valid
302 one if it isn't.
303 For the strange Win32 failures.
304
305 - fix a copy and paste error in pod in samples/samp-form.cgi

TC
307Imager 1.004_003 - 23 Mar 2016
308================
309
bd2d657d
TC
310 - add some extra error reporting to the I/O layers tests, this might
311 help catch a failure seen on Win32.

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

TC
322Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
323================
324
08914ed1
TC
325 - re-work the t/200-file/400-basic.t to correctly handle failures
326 It's custom ok() function didn't have a prototype and didn't use scalar().
327 This caused ok() to use the note instead of the value being tested when
328 the method called returned an empty list. For an example of the problem
e6226ce5 329 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 330
a2791e47
TC
331 - remove some noise from when Imager tried to work with bugs in old
332 versions of giflib. I can't do much about the new bugs.
08914ed1 333
e6226ce5
TC
334 - the new autolevels filter (Imager 0.99) used an integer for the
335 sample scaling factor which caused the top output level to be too
336 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
337 https://rt.cpan.org/Ticket/Display.html?id=111871
338
e6226ce5 339 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
340 minimum and maximum luminance from the histogram. This slightly
341 reduced the contrast of the output image.
342 https://rt.cpan.org/Ticket/Display.html?id=111871
343
344 - the new autolevels filter now uses a lookup table for 8-bit images
345 to avoid a floating point multiply for each sample.
346 https://rt.cpan.org/Ticket/Display.html?id=111871
347
e6226ce5
TC
348 - fixed several memory leaks detected by valgrind:
349
350 - addcolors() leaked the temporary array of colors supplied to the
351 internal API
352
353 - make_palette() leaked the temporary image array (not the images
354 themselves) passed to the internal API.
355
356 - combine()/i_combine() leaked its working row buffers
357
358 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
359 buffer if there were too many colors
360
361 - getcolorcount()/i_count_colors() leaked the sample buffer if
362 there were too many colors.
363
364 - the nearest_color filter (undocumented until I find a use for it)
365 leaked both temporaries passed to the API and internal buffers
366
a2791e47
TC
367 - the internal process of upgrading a paletted image to a direct
368 color image would leak a context object reference count.
369
370 - a write failure when writing to a GIF file could leak memory.
371
372 - failing to write to a 1-bit/pixel ICO image could leak memory.
373
374 - Imager no longer deliberately leaks the context object from the
375 initial thread. This was done to ensure there was always a context
376 object available, but the code that needed that now handles the
377 lack correctly,
378
e6226ce5
TC
379 - fixed some uninitialized memory usage detected by valgrind:
380
381 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
382 i_matrix_transform_bg() didn't initialize a working color value
383 if there was zero pixel coverage.
384
385 - i_ft2_cp() didn't initialize the complete color when producing an
386 intermediate image. This caused uninitialized value usage when
387 logging the color.

392 - Imager::Color::Table is now pre-loaded by the preload() method.
393 https://rt.cpan.org/Ticket/Display.html?id=104896
394
395 - fix an assertion triggered under perl 5.23.4.
396 Thanks to A. Sinan Unur for the report and the patch.

405Imager 1.003 - 12 May 2015
406============
407
0fda3cfd
TC
408 - update 1.002 release notes to include the center change for filled
409 circle drawing.
410
411 - flood_fill() would escape beyond a 4-connected space under some
412 circumstances.
413 Added many more flood_fill() tests.

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

447
448 An untranslated image would be unusable as image data, so
449 colormodel() would return "unknown" in this case.
450
451 Similarly a CMYK image might be returned as an "unknown" color
452 model image, if the caller chooses to disable translation to
453 RGB.

559 - Imager::File::PNG now supports libpng 1.6.10.
560 1.6.10 changed CRC errors from benign errors to normal errors,
561 which broke the test which used CRC errors to check for benign
562 error support. Switched to using a 1-bit grey-scale image with a
563 palette to test for benign errors.

567===========
568
f84f86a2
TC
569Incompatible changes:
570
571 - the return value of setpixel() has changed.
572
573 Previously the return values for undrawable pixels vs caller errors
574 changed depending on whether you used the multiple pixel calling
575 mechanism, or the single pixel mechanism.
576
577 Now:
578
579 - for an invalid parameter, such as an unknown colour, or missing
580 parameter, an empty list (or undef in scalar context) is
581 returned, and errstr() is set,
582
583 - otherwise the number of pixels drawn is returned. If none of
584 the pixels could be drawn (they were all outside the image), "0
585 but true" is returned.

587 https://rt.cpan.org/Ticket/Display.html?id=87650
588
589Other changes:
590
6ba09ab9
TC
591 - when drawing on an image with an alpha channel where the source
592 minimum is greater than zero, Imager would read from beyond the end
593 of a malloc() allocated buffer. In rare circumstances this could
594 lead to some of the source image not being written to the target
595 image, or possibly to a segmentation fault.
596 I don't believe this has any security concerns beyond that.
597
0d052fd9
TC
598 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
599 text drawn would be nonsense. This would also read beyond the end
600 of a malloced buffer.
601
13671b17

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

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

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

913Other changes:
914
915 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
916 internals, those names only matter for the XS interface.
917
918 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
919 the API level compiled into a loadable module such as
920 Imager::File::GIF doesn't match that of Imager. Previously it
921 could be difficult to determine exactly which module was failing to
922 load.
923 https://rt.cpan.org/Ticket/Display.html?id=77173
924
925 - added Imager->check_file_limits() as an interface to the
926 i_int_check_image_file_limits() API.

TC
943 - when downconverting samples (eg. from floating point to 8 bit)
944 Imager now rounds the sample value rather than attempting to
945 allocate input values over output values equally. The old
946 behaviour had the probably surprising effect of converting a
947 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
948 2.
949 This may result in slightly different 8 or 16-bit output images.

951 - BI_BITFIELD BMP images were handled incorrectly, both in

955
956 - some odd width BMP BI_RLE4 images use run lengths that run one off
957 the edge of the image. Imager now allows this, discarding the
958 extra column.

972

977 https://rt.cpan.org/Ticket/Display.html?id=74043
978
979 - if a probe includes testcode, Imager::Probe now checks that code as
980 part of the process of checking each configuration rather than as a
981 post test of the found configuration. This allows alternate
982 configurations to be checked if a matching but non-working
983 configuration is found.

1059 - setsamples() is now a true complement to getsamples() - it can

1221 - io_glue I/O buffering re-work:
1222
1223 - reorganize io_glue to do it's own buffering by default
1224
1225 - the unbuffered functions are available as i_io_raw_read() (or
1226 raw_read() from perl) etc but are not recommended for typical
1227 use.
1228
1229 - use the new i_io_peekn() when checking for file magic to avoid
1230 seek, allowing Imager to detect the file type and read the file
1231 from an unseekable stream (for formats that don't use random
1232 access)

1240 https://rt.cpan.org/Ticket/Display.html?id=69912
1241
1242 - the callback IO object did its own buffering, controlled by the
1243 maxbuffer parameter supplied to the read() and write() methods.
1244 This buffering has been removed, to avoid redundancy with the
1245 common io_glue buffering. This also avoids a bug in that code
1246 which could rarely pass a zero length to the read callback and
1247 then panic about the result.
1248
1249 - the callback IO object now tests the result of calling the close
1250 callback, which should return true for success.
1251
1252 - the PNM reader did its own buffering. This buffering has been
1253 removed to avoid redundancy with the common io_glue buffering.
1254
1255 - previously the read handlers for fd and callback I/O layers would
1256 call the underlying interface (POSIX read or your supplied callback)
1257 until it filled the buffer. It now only makes one call.
1258
1259 - added public constructors for I/O layer objects (see Imager::IO)
1260
1261 - all core file handlers now use the i_io_foo() wrappers to gain
1262 access to buffered I/O rather than calling the I/O layer
1263 callbacks directly.
1264
1265 - all core file handlers now check for error on close.
1266
1267 - Backward compatibility: if you hava custom file handlers, you can
1268 use i_io_write() etc since they're available as macros in older
1269 versions of Imager.
1270
1271 - eliminate the final remnants of io_glue_commit_types().
1272
1273 - bump IMAGER_API_VERSION, since the above may break assumptions.

1336Imager 0.84_01 - 8 Aug 2011
1337==============
1338
1339Development release as a sanity check for the types re-work.
8d14daab
TC
1340
1341Massive types re-work:
1342
1343 - the type used internally for pixel co-ordinates and image sizes is
1344 now 64-bit on 64-bit platforms (at least sane ones).
1345
1346 - size_t is now used consistently for memory block sizes.
1347
1348 - since this changes the binary interface, the Imager API version has
1349 been incremented. Any module that uses the API will need to be
1350 rebuilt. In most cases that will be enough, but calls to any APIs
1351 that take a pointer to image sizes may need source changes.
1352
1353 - you should be able to create very large images on 64-bit systems,
1354 if you have enough memory. Successfully created a 32768 x 49192 x
1355 3 channel image, filled with a tiled image and scaled it. The
1356 unscaled image was also successfully saved to a JPEG.
1357
1358 - check the image size before attempting to write BMP, GIF, JPEG,
1359 PNG, SGI, TGA, TIFF images.
1360
1361 - correctly handle reading TGA images over 32767 pixels wide or tall.
1362
1363Incidental changes:
1364
1365 - the gif_left and gif_top tags are now clamped to non-negative
1366 values when writing a GIF image.
1367
1368 - removed dead callback read/write code
1369
1370The default maximum memory size when reading files is now 1G.

2024
2025 - rubthrough() now falls back to pasting when the source doesn't have

2400Imager 0.55 - 16 Dec 2006
2401===========
2402
2403This is primarily a bug fix release.
2404
2405Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2406
2407There is one new feature:
2408
2409 - the Win32 font driver now supports UTF8 (RT 22166)
2410 http://www.cpanforum.com/threads/3276
2411 http://rt.cpan.org/Ticket/Display.html?id=22166
2412
2413Several bugs were fixed:
2414
2415 - the string() method would not output the string "0"
2416 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2417
2418 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2419 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2420
2421 - the gif_disposal and gif_user_input tags weren't being read from
2422 the file correctly
2423 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2424
2425 - gif.c was failing to build under MSVC
2426 http://rt.cpan.org/Ticket/Display.html?id=23922
2427
2428 - in some cases strings passed to the string() method were treated as
2429 terminated by NUL (chr 0)
2430 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2431
2432 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2433 that's the default build name for zlib on Win32.
2434 http://rt.cpan.org/Ticket/Display.html?id=23064
2435
2436 - search $Config{incpath} for headers too, which we should have been
2437 doing all along.
2438
2439Win32 font driver fixes:
2440
2441 - the global descent value from bounding box was the wrong sign
2442 http://www.cpanforum.com/threads/3276
2443
2444 - if the first or last glyph overflowed the left or right side of the
2445 advance width they would be clipped
2446
2447
2448Imager 0.54 - 14 Sep 2006
2449===========
2450
2451This is primarily a feature release:
2452
2453 - a new qtype value 'mixing' has been added to the scale()
2454 method. This is faster than 'normal', slower than 'preview'. This
2455 is based on the method used by pnmscale, and seems to produce less
2456 blurry results than normal.
2457 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2458
2459 - the rubthrough() method can now render onto images with an alpha
2460 channel.
2461 http://rt.cpan.org/Ticket/Display.html?id=20678
2462
2463 - the read_multi() method now falls back to calling doing a single
2464 image read via the read() method and write_multi() will now fall
2465 back to calling write() if a single image is supplied. This means
2466 you can simply call the read_multi() or write_multi() functions
2467 without having to check if the type is formatted by that method.
2468 http://rt.cpan.org/Ticket/Display.html?id=19457
2469 http://rt.cpan.org/Ticket/Display.html?id=19458
2470
2471 - the GIF loop extension can now be written. If you don't have
2472 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2473 should upgrade.
2474 http://rt.cpan.org/Ticket/Display.html?id=21185
2475
2476 - getscanline() and setscanline() can now read/write palette index
2477 based data from/to the image for paletted images, by setting type to
2478 'index'.
2479 http://rt.cpan.org/Ticket/Display.html?id=20338
2480
2481 - we no longer hassle you to disable GIF support
2482 http://rt.cpan.org/Ticket/Display.html?id=20687
2483
2484 - minor documentation fixes
2485
2486
2487Imager 0.53 - 26 Jul 2006
2488===========
2489
2490This is a bugfix release.
2491
2492Some test code was left in a code path not covered by the test
2493suite. A test was added to cover this code path and the test code was
2494removed.
2495http://rt.cpan.org/Public/Bug/Display.html?id=20705

2497
2498Imager 0.52 - 25 Jul 2006
2499===========
2500
2501This is primarily a feature release, but contains a fair few bug
2502fixes, new features:
2503
2504 - ability to read and write MS Windows ICO and CUR files
2505
2506 - you can now add file format plugins to support new file formats
2507
2508 - add POD coverage tests
2509
2510 - setcolors() and addcolors() now accept color names and so on
2511 instead of requiring Imager::Color objects.
2512 http://rt.cpan.org/Ticket/Display.html?id=20056
2513
2514 - flood_fill() can now fill to a specified border color instead of
2515 just to the area the same color as the seed.
2516 http://rt.cpan.org/Ticket/Display.html?id=19618
2517
2518
2519Bug fixes:
2520
2521 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2522 calculating the advance width.
2523 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2524
2525 - bounding_box for the T1 driver wasn't including leading and
2526 trailing spaces in the bounding box as the other drivers did, it also
2527 produced strange results for empty strings or strings containing only
2528 spaces
2529
2530 - when reading CMYK jpeg images they were being transferred to the
2531 image object as is, producing a four channel image. It only looked ok
2532 due to an old still unfixed Photoshop bug. We now convert from the
2533 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2534 http://rt.cpan.org/Ticket/Display.html?id=20416
2535
2536 - reading a CYMK TIFF would result in a 4 channel image, reading any
2537 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2538 result in an error.
2539 http://rt.cpan.org/Ticket/Display.html?id=20415
2540
2541 - added /usr/local/include to the default include search path, since
2542 we were already searching /usr/local/lib for libraries.
2543
2544And various minor fixes and documentation updates.
2545
2546
2547Imager 0.51 - 23 Apr 2006
