25 identify the file type match reality.
26 https://rt.cpan.org/Ticket/Display.html?id=72475

28 - read() now uses $FORMATGUESS if it can't determine the file type
29 based on the file header, to match read_multi().
30
31 - re-work and add tests for def_guess_type(). def_guess_type() no
32 longer returns any random file extension as the file type.

81 it.
82
5efba0c6
TC
83 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
84 to synthesize it from overloaded "".

90 creation.
91

93 engine.
94
6e938c74
TC
95 - the font has_chars() method now returns perl's true and false
96 values in list context rather than integers, which should be more
97 efficient.

113
336ce474
TC
114 - we rely on Config.pm's d_vsnprintf as to whether we use
115 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
116 though it only has _ prefixed versions of these. Define our own
117 prefixed names on Win32.

6d5c85a2 127==============
a7e32beb
TC
128
129 - add simple tests for the Imager::Test test_image generators
130
6d5c85a2
TC
131 - io_glue I/O buffering re-work:
132
133 - reorganize io_glue to do it's own buffering by default
134
135 - the unbuffered functions are available as i_io_raw_read() (or
136 raw_read() from perl) etc but are not recommended for typical
137 use.
138
139 - use the new i_io_peekn() when checking for file magic to avoid
140 seek, allowing Imager to detect the file type and read the file
141 from an unseekable stream (for formats that don't use random
142 access)
143
144 - added several new I/O layer API functions.
145
146 - fix the TGA performance problem, most noticably on Win32
147 https://rt.cpan.org/Ticket/Display.html?id=70037
148
149 - TIFF now uses wrapper functions of the correct types to avoid casts
150 https://rt.cpan.org/Ticket/Display.html?id=69912
151
152 - the callback IO object did its own buffering, controlled by the
153 maxbuffer parameter supplied to the read() and write() methods.
154 This buffering has been removed, to avoid redundancy with the
155 common io_glue buffering. This also avoids a bug in that code
156 which could rarely pass a zero length to the read callback and
157 then panic about the result.
158
159 - the callback IO object now tests the result of calling the close
160 callback, which should return true for success.
161
162 - the PNM reader did its own buffering. This buffering has been
163 removed to avoid redundancy with the common io_glue buffering.
164
165 - previously the read handlers for fd and callback I/O layers would
166 call the underlying interface (POSIX read or your supplied callback)
167 until it filled the buffer. It now only makes one call.
168
169 - added public constructors for I/O layer objects (see Imager::IO)
170
171 - all core file handlers now use the i_io_foo() wrappers to gain
172 access to buffered I/O rather than calling the I/O layer
173 callbacks directly.
174
175 - all core file handlers now check for error on close.
176
177 - Backward compatibility: if you hava custom file handlers, you can
178 use i_io_write() etc since they're available as macros in older
179 versions of Imager.
180
181 - eliminate the final remnants of io_glue_commit_types().
182
183 - bump IMAGER_API_VERSION, since the above may break assumptions.
184
185 - removed the long unused i_gen_reader() and i_gen_writer() utility
186 functions.

6ad7e4bc
TC
189===========
190
0c647c9a
TC
191The main changes in the release versus 0.84 are:
192
193 - on 64-bit systems, 64-bit types are consistently used for image
194 dimensions and co-ordinated, and for memory block sizes.
195
196 - handle IFD loops in TIFF files correctly. Previously this would
197 lead to an infinite loop.
198
6ad7e4bc
TC
199Bug fixes:
200
201 - fix the link in the getheight() entry in the method index

207favourable.
6b7197d0
TC
208
209Bug fixes:
210
211 - the image file limits set by set_file_limits() weren't being
212 checked when reading TIFF files.
213 https://rt.cpan.org/Ticket/Display.html?id=69915
214
5970bd39
TC
215 - Provide more information about file format module load errors on a
216 failed image file read() or write().
217 https://rt.cpan.org/Ticket/Display.html?id=69194
218
4ce3551c
TC
219 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
220 through TIFF images, since it checks for IFD loops.
221 https://rt.cpan.org/Ticket/Display.html?id=69914
222
a16bca6d
TC
223 - don't leak memory when out of range palette indexes are supplied to
224 setscanline().
225 https://rt.cpan.org/Ticket/Display.html?id=69242
226
227 - require a later version of CPAN::Meta to ensure JSON::PP and
228 CPAN::Meta::YAML are available.
229 https://rt.cpan.org/Ticket/Display.html?id=69008
230
ac575c5f
TC
231 - hoist the per-line calculations for the flines implementations, and
232 modernize the tests a bit.
233 https://rt.cpan.org/Ticket/Display.html?id=70126
234
86c8d19a
TC
235 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
236 them when available.

238
a3fd7df7
TC
239 - if t1lib failed to reinitialize it would be left as marked

246Imager 0.84_01 - 8 Aug 2011
247==============
248
249Development release as a sanity check for the types re-work.
8d14daab
TC
250
251Massive types re-work:
252
253 - the type used internally for pixel co-ordinates and image sizes is
254 now 64-bit on 64-bit platforms (at least sane ones).
255
256 - size_t is now used consistently for memory block sizes.
257
258 - since this changes the binary interface, the Imager API version has
259 been incremented. Any module that uses the API will need to be
260 rebuilt. In most cases that will be enough, but calls to any APIs
261 that take a pointer to image sizes may need source changes.
262
263 - you should be able to create very large images on 64-bit systems,
264 if you have enough memory. Successfully created a 32768 x 49192 x
265 3 channel image, filled with a tiled image and scaled it. The
266 unscaled image was also successfully saved to a JPEG.
267
268 - check the image size before attempting to write BMP, GIF, JPEG,
269 PNG, SGI, TGA, TIFF images.
270
271 - correctly handle reading TGA images over 32767 pixels wide or tall.
272
273Incidental changes:
274
275 - the gif_left and gif_top tags are now clamped to non-negative
276 values when writing a GIF image.
277
278 - removed dead callback read/write code
279
280The default maximum memory size when reading files is now 1G.

TC
307 - convert colors to grayscale if the supplied (or generated) palette
308 contains only grays when performing error diffusion color
309 translation.
310 https://rt.cpan.org/Ticket/Display.html?id=68508
311
59c150a4
TC
312 - writing a paletted image to GIF wouldn't always use the colors
313 supplied (or generated, eg. via make_colors => "mono"), which was
314 confusing at best.
315 https://rt.cpan.org/Ticket/Display.html?id=67912
316
5b480b14
TC
317 - replace (imager|tony)@imager.perl.org in the doc, since I don't

341 - compose() with the target, source or mask position off the top or
342 left of the target image didn't clip the source image correctly.
343 https://rt.cpan.org/Ticket/Display.html?id=67220
344
345 - compose() now returns a useful error message on a non-positive
346 opacity.
347
348 - compose.im now at 100% test coverage. (As opposed to, umm, much,
349 much less.)

TC
352===========
353
354Bug fixes:
355
356 - eliminate calls to i_has_format() from the test suite, since it's
357 no longer a useful way to check for file format support. Eliminate
358 i_has_format() from the functions exposed via XS.
359 https://rt.cpan.org/Ticket/Display.html?id=65863
360
7540f84a
TC
361 - eliminate calls to note(), which isn't in the (very old) version of
362 Test::More we have as a pre-requisite. note() is modern enough
363 that I don't feel a need to require a Test::More upgrade for it.
364 https://rt.cpan.org/Ticket/Display.html?id=65864

376 downgrade the version in this file.
377 https://rt.cpan.org/Ticket/Display.html?id=66250
378
379 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
380 that option for the directories that would normally go in
381 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

916This release primarily contains changes to improve ease of use -
917rather than you having to convert images to the appropriate number of
918channels, Imager handles it internally. How to handle drawing colors
919and the default combine mode is a thornier problem left for some other
920release.

TC
925 - moved the imtoc.perl code into Imager::Preprocess
926
927 - paste() and rubthrough() now adapt the source image data to the
928 destination, so you can now safely paste/rubthrough from greyscale
929 images to color images or back, or from alpha channel images to
930 noalpha channels or back.
931 https://rt.cpan.org/Ticket/Display.html?id=30908
932
933 - rubthrough() now falls back to pasting when the source doesn't have
934 an alpha channel. This effectively treats the source as having a
935 max alpha channel, the right thing to do.
936 http://rt.cpan.org/Ticket/Display.html?id=29944
937
938 - re-worked most of the area filling code to use a common set of
939 functions when filling.
940 Corrected normal combine mode.
941 Rewrote most of the combine modes to match the way the SVG draft
942 defines them with respect to a translucent source and destination.
943 Added tests for translucent source and destination.
944 Added tests to check 8-bit/sample and double/sample combines work
945 similarly.

969 - mixing qtype scaling now sets all channels of a pixel to zero if
970 the pixel has zero coverage (zero alpha). This should produce more
971 compressible output files.

977 I'm not changing the #! lines of the sample code, since it's sample

981 - some TGA images weren't being detected correctly as TGA images
982 https://rt.cpan.org/Ticket/Display.html?id=32925
983
984 - handling of the left-over bit for 16-bit/pixel TGA images has been
985 changed to match the behaviour of the GIMP. Previously the bit
986 being set was treated as an opaque pixel, but one user reported a
987 problem with loading such an image. I haven't been able to find any
988 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
989 I'll match it's behaviour. See issue 114913 in the GIMP's
990 bugzilla.

1000 - the old dynaload code used Mach API functions to load dynamic
1001 libraries on Mac OS X. These APIs have been deprecated in OS X
1002 10.5 and were causing some build problems.
1003 So henceforth Imager uses the dlopen() family of functions, and you
1004 will need version 10.3 or later of OS X.

1335
1336 - in some cases strings passed to the string() method were treated as
1337 terminated by NUL (chr 0)
1338 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1339
1340 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1341 that's the default build name for zlib on Win32.
1342 http://rt.cpan.org/Ticket/Display.html?id=23064
1343
1344 - search $Config{incpath} for headers too, which we should have been
1345 doing all along.
1346
1347Win32 font driver fixes:
1348
1349 - the global descent value from bounding box was the wrong sign
1350 http://www.cpanforum.com/threads/3276
1351
1352 - if the first or last glyph overflowed the left or right side of the
1353 advance width they would be clipped

1356Imager 0.54 - 14 Sep 2006
1357===========
1358
1359This is primarily a feature release:
1360
1361 - a new qtype value 'mixing' has been added to the scale()
1362 method. This is faster than 'normal', slower than 'preview'. This
1363 is based on the method used by pnmscale, and seems to produce less
1364 blurry results than normal.
1365 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1366
1367 - the rubthrough() method can now render onto images with an alpha
1368 channel.
1369 http://rt.cpan.org/Ticket/Display.html?id=20678
1370
1371 - the read_multi() method now falls back to calling doing a single
1372 image read via the read() method and write_multi() will now fall
1373 back to calling write() if a single image is supplied. This means
1374 you can simply call the read_multi() or write_multi() functions
1375 without having to check if the type is formatted by that method.
1376 http://rt.cpan.org/Ticket/Display.html?id=19457
1377 http://rt.cpan.org/Ticket/Display.html?id=19458
1378
1379 - the GIF loop extension can now be written. If you don't have
1380 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1381 should upgrade.
1382 http://rt.cpan.org/Ticket/Display.html?id=21185
1383
1384 - getscanline() and setscanline() can now read/write palette index
1385 based data from/to the image for paletted images, by setting type to
1386 'index'.
1387 http://rt.cpan.org/Ticket/Display.html?id=20338
1388
1389 - we no longer hassle you to disable GIF support
1390 http://rt.cpan.org/Ticket/Display.html?id=20687
1391
1392 - minor documentation fixes
1393
1394
1395Imager 0.53 - 26 Jul 2006
1396===========
1397
1398This is a bugfix release.
1399
1400Some test code was left in a code path not covered by the test
1401suite. A test was added to cover this code path and the test code was
1402removed.

1404
1405
1406Imager 0.52 - 25 Jul 2006
1407===========
1408
1409This is primarily a feature release, but contains a fair few bug
1410fixes, new features:
1411
1412 - ability to read and write MS Windows ICO and CUR files
1413
1414 - you can now add file format plugins to support new file formats
1415
1416 - add POD coverage tests
1417
1418 - setcolors() and addcolors() now accept color names and so on
1419 instead of requiring Imager::Color objects.
1420 http://rt.cpan.org/Ticket/Display.html?id=20056
1421
1422 - flood_fill() can now fill to a specified border color instead of
1423 just to the area the same color as the seed.
1424 http://rt.cpan.org/Ticket/Display.html?id=19618
1425
1426
1427Bug fixes:
1428
1429 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1430 calculating the advance width.
1431 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1432
1433 - bounding_box for the T1 driver wasn't including leading and
1434 trailing spaces in the bounding box as the other drivers did, it also
1435 produced strange results for empty strings or strings containing only
1436 spaces
1437
1438 - when reading CMYK jpeg images they were being transferred to the
1439 image object as is, producing a four channel image. It only looked ok
1440 due to an old still unfixed Photoshop bug. We now convert from the
1441 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1442 http://rt.cpan.org/Ticket/Display.html?id=20416
1443
1444 - reading a CYMK TIFF would result in a 4 channel image, reading any
1445 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1446 result in an error.
1447 http://rt.cpan.org/Ticket/Display.html?id=20415
1448
1449 - added /usr/local/include to the default include search path, since
1450 we were already searching /usr/local/lib for libraries.
1451
1452And various minor fixes and documentation updates.
1453
