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

51 based on the file header, to match read_multi().
52
53 - re-work and add tests for def_guess_type(). def_guess_type() no
54 longer returns any random file extension as the file type.

102 - depend on Scalar::Util, since we use it and older perls don't have
103 it.
104
5efba0c6
TC
105 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
106 to synthesize it from overloaded "".
107
73e3ff55
TC
108 - use T1_StrError() for error messages on modern libt1

113
114 - Imager::Font->new now produces better error messages for the T1
115 engine.
116
6e938c74
TC
117 - the font has_chars() method now returns perl's true and false
118 values in list context rather than integers, which should be more
119 efficient.

134 https://rt.cpan.org/Ticket/Display.html?id=71675
135
336ce474
TC
136 - we rely on Config.pm's d_vsnprintf as to whether we use
137 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
138 though it only has _ prefixed versions of these. Define our own
139 prefixed names on Win32.

6d5c85a2 149==============
a7e32beb
TC
150
151 - add simple tests for the Imager::Test test_image generators
152
6d5c85a2
TC
153 - io_glue I/O buffering re-work:
154
155 - reorganize io_glue to do it's own buffering by default
156
157 - the unbuffered functions are available as i_io_raw_read() (or
158 raw_read() from perl) etc but are not recommended for typical
159 use.
160
161 - use the new i_io_peekn() when checking for file magic to avoid
162 seek, allowing Imager to detect the file type and read the file
163 from an unseekable stream (for formats that don't use random
164 access)
165
166 - added several new I/O layer API functions.
167
168 - fix the TGA performance problem, most noticably on Win32
169 https://rt.cpan.org/Ticket/Display.html?id=70037
170
171 - TIFF now uses wrapper functions of the correct types to avoid casts
172 https://rt.cpan.org/Ticket/Display.html?id=69912
173
174 - the callback IO object did its own buffering, controlled by the
175 maxbuffer parameter supplied to the read() and write() methods.
176 This buffering has been removed, to avoid redundancy with the
177 common io_glue buffering. This also avoids a bug in that code
178 which could rarely pass a zero length to the read callback and
179 then panic about the result.
180
181 - the callback IO object now tests the result of calling the close
182 callback, which should return true for success.
183
184 - the PNM reader did its own buffering. This buffering has been
185 removed to avoid redundancy with the common io_glue buffering.
186
187 - previously the read handlers for fd and callback I/O layers would
188 call the underlying interface (POSIX read or your supplied callback)
189 until it filled the buffer. It now only makes one call.
190
191 - added public constructors for I/O layer objects (see Imager::IO)
192
193 - all core file handlers now use the i_io_foo() wrappers to gain
194 access to buffered I/O rather than calling the I/O layer
195 callbacks directly.
196
197 - all core file handlers now check for error on close.
198
199 - Backward compatibility: if you hava custom file handlers, you can
200 use i_io_write() etc since they're available as macros in older
201 versions of Imager.
202
203 - eliminate the final remnants of io_glue_commit_types().
204
205 - bump IMAGER_API_VERSION, since the above may break assumptions.
206
207 - removed the long unused i_gen_reader() and i_gen_writer() utility
208 functions.

TC
211===========
212
0c647c9a
TC
213The main changes in the release versus 0.84 are:
214
215 - on 64-bit systems, 64-bit types are consistently used for image
216 dimensions and co-ordinated, and for memory block sizes.
217
218 - handle IFD loops in TIFF files correctly. Previously this would
219 lead to an infinite loop.
220
6ad7e4bc
TC
221Bug fixes:
222

TC
230
231Bug fixes:
232
233 - the image file limits set by set_file_limits() weren't being
234 checked when reading TIFF files.
235 https://rt.cpan.org/Ticket/Display.html?id=69915
236
5970bd39
TC
237 - Provide more information about file format module load errors on a
238 failed image file read() or write().
239 https://rt.cpan.org/Ticket/Display.html?id=69194
240
4ce3551c
TC
241 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
242 through TIFF images, since it checks for IFD loops.
243 https://rt.cpan.org/Ticket/Display.html?id=69914
244
a16bca6d
TC
245 - don't leak memory when out of range palette indexes are supplied to
246 setscanline().
247 https://rt.cpan.org/Ticket/Display.html?id=69242
248
249 - require a later version of CPAN::Meta to ensure JSON::PP and
250 CPAN::Meta::YAML are available.

252
ac575c5f
TC
253 - hoist the per-line calculations for the flines implementations, and

256
86c8d19a

268Imager 0.84_01 - 8 Aug 2011
269==============
270
271Development release as a sanity check for the types re-work.
8d14daab
TC
272
273Massive types re-work:
274
275 - the type used internally for pixel co-ordinates and image sizes is
276 now 64-bit on 64-bit platforms (at least sane ones).
277
278 - size_t is now used consistently for memory block sizes.
279
280 - since this changes the binary interface, the Imager API version has
281 been incremented. Any module that uses the API will need to be
282 rebuilt. In most cases that will be enough, but calls to any APIs
283 that take a pointer to image sizes may need source changes.
284
285 - you should be able to create very large images on 64-bit systems,
286 if you have enough memory. Successfully created a 32768 x 49192 x
287 3 channel image, filled with a tiled image and scaled it. The
288 unscaled image was also successfully saved to a JPEG.
289
290 - check the image size before attempting to write BMP, GIF, JPEG,
291 PNG, SGI, TGA, TIFF images.
292
293 - correctly handle reading TGA images over 32767 pixels wide or tall.
294
295Incidental changes:
296
297 - the gif_left and gif_top tags are now clamped to non-negative
298 values when writing a GIF image.
299
300 - removed dead callback read/write code
301
302The default maximum memory size when reading files is now 1G.

331 translation.
332 https://rt.cpan.org/Ticket/Display.html?id=68508
333
59c150a4
TC
334 - writing a paletted image to GIF wouldn't always use the colors
335 supplied (or generated, eg. via make_colors => "mono"), which was
336 confusing at best.
337 https://rt.cpan.org/Ticket/Display.html?id=67912
338
5b480b14
TC
339 - replace (imager|tony)@imager.perl.org in the doc, since I don't

363 - compose() with the target, source or mask position off the top or
364 left of the target image didn't clip the source image correctly.

366
367 - compose() now returns a useful error message on a non-positive
368 opacity.
369
370 - compose.im now at 100% test coverage. (As opposed to, umm, much,

TC
374===========
375
376Bug fixes:
377
378 - eliminate calls to i_has_format() from the test suite, since it's
379 no longer a useful way to check for file format support. Eliminate
380 i_has_format() from the functions exposed via XS.

382
7540f84a
TC
383 - eliminate calls to note(), which isn't in the (very old) version of
384 Test::More we have as a pre-requisite. note() is modern enough
385 that I don't feel a need to require a Test::More upgrade for it.

398 downgrade the version in this file.
399 https://rt.cpan.org/Ticket/Display.html?id=66250
400
401 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
402 that option for the directories that would normally go in
403 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

940This release primarily contains changes to improve ease of use -
941rather than you having to convert images to the appropriate number of
942channels, Imager handles it internally. How to handle drawing colors
943and the default combine mode is a thornier problem left for some other
944release.

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

951 - paste() and rubthrough() now adapt the source image data to the
952 destination, so you can now safely paste/rubthrough from greyscale
953 images to color images or back, or from alpha channel images to
954 noalpha channels or back.
955 https://rt.cpan.org/Ticket/Display.html?id=30908
956
957 - rubthrough() now falls back to pasting when the source doesn't have
958 an alpha channel. This effectively treats the source as having a
959 max alpha channel, the right thing to do.
960 http://rt.cpan.org/Ticket/Display.html?id=29944
961
962 - re-worked most of the area filling code to use a common set of
963 functions when filling.
964 Corrected normal combine mode.
965 Rewrote most of the combine modes to match the way the SVG draft
966 defines them with respect to a translucent source and destination.
967 Added tests for translucent source and destination.
968 Added tests to check 8-bit/sample and double/sample combines work
969 similarly.

1008 - handling of the left-over bit for 16-bit/pixel TGA images has been
1009 changed to match the behaviour of the GIMP. Previously the bit
1010 being set was treated as an opaque pixel, but one user reported a
1011 problem with loading such an image. I haven't been able to find any
1012 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1013 I'll match it's behaviour. See issue 114913 in the GIMP's
1014 bugzilla.

1332Imager 0.55 - 16 Dec 2006
1333===========
1334
1335This is primarily a bug fix release.
1336
1337Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1338
1339There is one new feature:
1340
1341 - the Win32 font driver now supports UTF8 (RT 22166)
1342 http://www.cpanforum.com/threads/3276
1343 http://rt.cpan.org/Ticket/Display.html?id=22166
1344
1345Several bugs were fixed:
1346
1347 - the string() method would not output the string "0"
1348 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1349
1350 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1351 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1352
1353 - the gif_disposal and gif_user_input tags weren't being read from
1354 the file correctly
1355 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1356
1357 - gif.c was failing to build under MSVC
1358 http://rt.cpan.org/Ticket/Display.html?id=23922
1359
1360 - in some cases strings passed to the string() method were treated as
1361 terminated by NUL (chr 0)
1362 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1363
1364 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1365 that's the default build name for zlib on Win32.
1366 http://rt.cpan.org/Ticket/Display.html?id=23064
1367
1368 - search $Config{incpath} for headers too, which we should have been
1369 doing all along.
1370
1371Win32 font driver fixes:
1372
1373 - the global descent value from bounding box was the wrong sign
1374 http://www.cpanforum.com/threads/3276
1375
1376 - if the first or last glyph overflowed the left or right side of the
1377 advance width they would be clipped
1378
1379
1380Imager 0.54 - 14 Sep 2006
1381===========
1382
1383This is primarily a feature release:
1384
1385 - a new qtype value 'mixing' has been added to the scale()
1386 method. This is faster than 'normal', slower than 'preview'. This
1387 is based on the method used by pnmscale, and seems to produce less
1388 blurry results than normal.
1389 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1390
1391 - the rubthrough() method can now render onto images with an alpha
1392 channel.
1393 http://rt.cpan.org/Ticket/Display.html?id=20678
1394
1395 - the read_multi() method now falls back to calling doing a single
1396 image read via the read() method and write_multi() will now fall
1397 back to calling write() if a single image is supplied. This means
1398 you can simply call the read_multi() or write_multi() functions
1399 without having to check if the type is formatted by that method.
1400 http://rt.cpan.org/Ticket/Display.html?id=19457
1401 http://rt.cpan.org/Ticket/Display.html?id=19458
1402
1403 - the GIF loop extension can now be written. If you don't have
1404 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1405 should upgrade.
1406 http://rt.cpan.org/Ticket/Display.html?id=21185
1407
1408 - getscanline() and setscanline() can now read/write palette index
1409 based data from/to the image for paletted images, by setting type to
1410 'index'.
1411 http://rt.cpan.org/Ticket/Display.html?id=20338
1412
1413 - we no longer hassle you to disable GIF support
1414 http://rt.cpan.org/Ticket/Display.html?id=20687
1415
1416 - minor documentation fixes
1417
1418
1419Imager 0.53 - 26 Jul 2006
1420===========
1421
1422This is a bugfix release.
1423
1424Some test code was left in a code path not covered by the test
1425suite. A test was added to cover this code path and the test code was
1426removed.

1428
1429
1430Imager 0.52 - 25 Jul 2006
1431===========
1432
1433This is primarily a feature release, but contains a fair few bug
1434fixes, new features:
1435
1436 - ability to read and write MS Windows ICO and CUR files
1437
1438 - you can now add file format plugins to support new file formats
1439
1440 - add POD coverage tests
1441
1442 - setcolors() and addcolors() now accept color names and so on
1443 instead of requiring Imager::Color objects.
1444 http://rt.cpan.org/Ticket/Display.html?id=20056
1445
1446 - flood_fill() can now fill to a specified border color instead of
1447 just to the area the same color as the seed.
1448 http://rt.cpan.org/Ticket/Display.html?id=19618
1449
1450
1451Bug fixes:
1452
1453 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1454 calculating the advance width.
1455 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1456
1457 - bounding_box for the T1 driver wasn't including leading and
1458 trailing spaces in the bounding box as the other drivers did, it also
1459 produced strange results for empty strings or strings containing only
1460 spaces
1461
1462 - when reading CMYK jpeg images they were being transferred to the
1463 image object as is, producing a four channel image. It only looked ok
1464 due to an old still unfixed Photoshop bug. We now convert from the
1465 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1466 http://rt.cpan.org/Ticket/Display.html?id=20416
1467
1468 - reading a CYMK TIFF would result in a 4 channel image, reading any
1469 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1470 result in an error.
1471 http://rt.cpan.org/Ticket/Display.html?id=20415
1472
1473 - added /usr/local/include to the default include search path, since
1474 we were already searching /usr/local/lib for libraries.
1475
1476And various minor fixes and documentation updates.
1477
1478

1485
1486 - fix mis-processing of the src_maxx and src_maxy parameters of the
1487 paste() method
1488 http://rt.cpan.org/Public/Bug/Display.html?id=18712
