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

41 based on the file header, to match read_multi().
42
43 - re-work and add tests for def_guess_type(). def_guess_type() no
44 longer returns any random file extension as the file type.

6e938c74
TC
107 - the font has_chars() method now returns perl's true and false

TC
126 - we rely on Config.pm's d_vsnprintf as to whether we use
127 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
128 though it only has _ prefixed versions of these. Define our own
129 prefixed names on Win32.

TC
140
141 - add simple tests for the Imager::Test test_image generators
142
6d5c85a2
TC
143 - io_glue I/O buffering re-work:
144
145 - reorganize io_glue to do it's own buffering by default
146
147 - the unbuffered functions are available as i_io_raw_read() (or
148 raw_read() from perl) etc but are not recommended for typical
149 use.
150
151 - use the new i_io_peekn() when checking for file magic to avoid
152 seek, allowing Imager to detect the file type and read the file
153 from an unseekable stream (for formats that don't use random
154 access)
155
156 - added several new I/O layer API functions.
157
158 - fix the TGA performance problem, most noticably on Win32
159 https://rt.cpan.org/Ticket/Display.html?id=70037
160
161 - TIFF now uses wrapper functions of the correct types to avoid casts
162 https://rt.cpan.org/Ticket/Display.html?id=69912
163
164 - the callback IO object did its own buffering, controlled by the
165 maxbuffer parameter supplied to the read() and write() methods.
166 This buffering has been removed, to avoid redundancy with the
167 common io_glue buffering. This also avoids a bug in that code
168 which could rarely pass a zero length to the read callback and
169 then panic about the result.
170
171 - the callback IO object now tests the result of calling the close
172 callback, which should return true for success.
173
174 - the PNM reader did its own buffering. This buffering has been
175 removed to avoid redundancy with the common io_glue buffering.
176
177 - previously the read handlers for fd and callback I/O layers would
178 call the underlying interface (POSIX read or your supplied callback)
179 until it filled the buffer. It now only makes one call.
180
181 - added public constructors for I/O layer objects (see Imager::IO)
182
183 - all core file handlers now use the i_io_foo() wrappers to gain
184 access to buffered I/O rather than calling the I/O layer
185 callbacks directly.
186
187 - all core file handlers now check for error on close.
188
189 - Backward compatibility: if you hava custom file handlers, you can
190 use i_io_write() etc since they're available as macros in older
191 versions of Imager.
192
193 - eliminate the final remnants of io_glue_commit_types().
194
195 - bump IMAGER_API_VERSION, since the above may break assumptions.
196
197 - removed the long unused i_gen_reader() and i_gen_writer() utility
198 functions.

201===========
202
0c647c9a
TC
203The main changes in the release versus 0.84 are:
204
205 - on 64-bit systems, 64-bit types are consistently used for image
206 dimensions and co-ordinated, and for memory block sizes.
207
208 - handle IFD loops in TIFF files correctly. Previously this would
209 lead to an infinite loop.
210

222
223 - the image file limits set by set_file_limits() weren't being
224 checked when reading TIFF files.

226
5970bd39

230
4ce3551c
TC
231 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
232 through TIFF images, since it checks for IFD loops.
233 https://rt.cpan.org/Ticket/Display.html?id=69914
234

TC
235 - don't leak memory when out of range palette indexes are supplied to
236 setscanline().
237 https://rt.cpan.org/Ticket/Display.html?id=69242
238
239 - require a later version of CPAN::Meta to ensure JSON::PP and

258Imager 0.84_01 - 8 Aug 2011
259==============
260
261Development release as a sanity check for the types re-work.
8d14daab
TC
262
263Massive types re-work:
264
265 - the type used internally for pixel co-ordinates and image sizes is
266 now 64-bit on 64-bit platforms (at least sane ones).
267
268 - size_t is now used consistently for memory block sizes.
269
270 - since this changes the binary interface, the Imager API version has
271 been incremented. Any module that uses the API will need to be
272 rebuilt. In most cases that will be enough, but calls to any APIs
273 that take a pointer to image sizes may need source changes.
274
275 - you should be able to create very large images on 64-bit systems,
276 if you have enough memory. Successfully created a 32768 x 49192 x
277 3 channel image, filled with a tiled image and scaled it. The
278 unscaled image was also successfully saved to a JPEG.
279
280 - check the image size before attempting to write BMP, GIF, JPEG,
281 PNG, SGI, TGA, TIFF images.
282
283 - correctly handle reading TGA images over 32767 pixels wide or tall.
284
285Incidental changes:
286
287 - the gif_left and gif_top tags are now clamped to non-negative
288 values when writing a GIF image.
289
290 - removed dead callback read/write code
291
292The default maximum memory size when reading files is now 1G.

321 translation.
322 https://rt.cpan.org/Ticket/Display.html?id=68508
323
59c150a4
TC
324 - writing a paletted image to GIF wouldn't always use the colors
325 supplied (or generated, eg. via make_colors => "mono"), which was
326 confusing at best.
327 https://rt.cpan.org/Ticket/Display.html?id=67912

364===========

366Bug fixes:
367
368 - eliminate calls to i_has_format() from the test suite, since it's
369 no longer a useful way to check for file format support. Eliminate
370 i_has_format() from the functions exposed via XS.

372
7540f84a
TC
373 - eliminate calls to note(), which isn't in the (very old) version of
374 Test::More we have as a pre-requisite. note() is modern enough
375 that I don't feel a need to require a Test::More upgrade for it.

388 downgrade the version in this file.
389 https://rt.cpan.org/Ticket/Display.html?id=66250
390
391 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
392 that option for the directories that would normally go in
393 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

930This release primarily contains changes to improve ease of use -
931rather than you having to convert images to the appropriate number of
932channels, Imager handles it internally. How to handle drawing colors
933and the default combine mode is a thornier problem left for some other
934release.

TC
939 - moved the imtoc.perl code into Imager::Preprocess
940
941 - paste() and rubthrough() now adapt the source image data to the
942 destination, so you can now safely paste/rubthrough from greyscale
943 images to color images or back, or from alpha channel images to
944 noalpha channels or back.
945 https://rt.cpan.org/Ticket/Display.html?id=30908
946
947 - rubthrough() now falls back to pasting when the source doesn't have
948 an alpha channel. This effectively treats the source as having a
949 max alpha channel, the right thing to do.
950 http://rt.cpan.org/Ticket/Display.html?id=29944
951
952 - re-worked most of the area filling code to use a common set of
953 functions when filling.
954 Corrected normal combine mode.
955 Rewrote most of the combine modes to match the way the SVG draft
956 defines them with respect to a translucent source and destination.
957 Added tests for translucent source and destination.
958 Added tests to check 8-bit/sample and double/sample combines work
959 similarly.

995 - some TGA images weren't being detected correctly as TGA images
996 https://rt.cpan.org/Ticket/Display.html?id=32925
997
998 - handling of the left-over bit for 16-bit/pixel TGA images has been
999 changed to match the behaviour of the GIMP. Previously the bit
1000 being set was treated as an opaque pixel, but one user reported a
1001 problem with loading such an image. I haven't been able to find any
1002 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1003 I'll match it's behaviour. See issue 114913 in the GIMP's
1004 bugzilla.

1014 - the old dynaload code used Mach API functions to load dynamic
1015 libraries on Mac OS X. These APIs have been deprecated in OS X
1016 10.5 and were causing some build problems.

1018 will need version 10.3 or later of OS X.

1334
1335Several bugs were fixed:
1336
1337 - the string() method would not output the string "0"
1338 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1339
1340 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1341 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1342
1343 - the gif_disposal and gif_user_input tags weren't being read from
1344 the file correctly
1345 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1346
1347 - gif.c was failing to build under MSVC
1348 http://rt.cpan.org/Ticket/Display.html?id=23922
1349
1350 - in some cases strings passed to the string() method were treated as
1351 terminated by NUL (chr 0)
1352 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1353
1354 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1355 that's the default build name for zlib on Win32.
1356 http://rt.cpan.org/Ticket/Display.html?id=23064
1357
1358 - search $Config{incpath} for headers too, which we should have been
1359 doing all along.
1360
1361Win32 font driver fixes:
1362
1363 - the global descent value from bounding box was the wrong sign
1364 http://www.cpanforum.com/threads/3276
1365
1366 - if the first or last glyph overflowed the left or right side of the
1367 advance width they would be clipped

1370Imager 0.54 - 14 Sep 2006
1371===========
1372
1373This is primarily a feature release:
1374
1375 - a new qtype value 'mixing' has been added to the scale()
1376 method. This is faster than 'normal', slower than 'preview'. This
1377 is based on the method used by pnmscale, and seems to produce less
1378 blurry results than normal.
1379 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1380
1381 - the rubthrough() method can now render onto images with an alpha
1382 channel.
1383 http://rt.cpan.org/Ticket/Display.html?id=20678
1384
1385 - the read_multi() method now falls back to calling doing a single
1386 image read via the read() method and write_multi() will now fall
1387 back to calling write() if a single image is supplied. This means
1388 you can simply call the read_multi() or write_multi() functions
1389 without having to check if the type is formatted by that method.
1390 http://rt.cpan.org/Ticket/Display.html?id=19457
1391 http://rt.cpan.org/Ticket/Display.html?id=19458
1392
1393 - the GIF loop extension can now be written. If you don't have
1394 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1395 should upgrade.
1396 http://rt.cpan.org/Ticket/Display.html?id=21185
1397
1398 - getscanline() and setscanline() can now read/write palette index
1399 based data from/to the image for paletted images, by setting type to
1400 'index'.
1401 http://rt.cpan.org/Ticket/Display.html?id=20338
1402
1403 - we no longer hassle you to disable GIF support
1404 http://rt.cpan.org/Ticket/Display.html?id=20687
1405
1406 - minor documentation fixes
1407
1408
1409Imager 0.53 - 26 Jul 2006
1410===========
1411
1412This is a bugfix release.
1413
1414Some test code was left in a code path not covered by the test
1415suite. A test was added to cover this code path and the test code was
1416removed.
1417http://rt.cpan.org/Public/Bug/Display.html?id=20705
1418
1419
1420Imager 0.52 - 25 Jul 2006
1421===========
1422
1423This is primarily a feature release, but contains a fair few bug
1424fixes, new features:
1425
1426 - ability to read and write MS Windows ICO and CUR files
1427
1428 - you can now add file format plugins to support new file formats
1429
1430 - add POD coverage tests
1431
1432 - setcolors() and addcolors() now accept color names and so on
1433 instead of requiring Imager::Color objects.
1434 http://rt.cpan.org/Ticket/Display.html?id=20056
1435
1436 - flood_fill() can now fill to a specified border color instead of
1437 just to the area the same color as the seed.
1438 http://rt.cpan.org/Ticket/Display.html?id=19618
1439
1440
1441Bug fixes:
1442
1443 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1444 calculating the advance width.
1445 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1446
1447 - bounding_box for the T1 driver wasn't including leading and
1448 trailing spaces in the bounding box as the other drivers did, it also
1449 produced strange results for empty strings or strings containing only
1450 spaces
1451
1452 - when reading CMYK jpeg images they were being transferred to the
1453 image object as is, producing a four channel image. It only looked ok
1454 due to an old still unfixed Photoshop bug. We now convert from the
1455 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1456 http://rt.cpan.org/Ticket/Display.html?id=20416
1457
1458 - reading a CYMK TIFF would result in a 4 channel image, reading any
1459 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1460 result in an error.
1461 http://rt.cpan.org/Ticket/Display.html?id=20415
1462
1463 - added /usr/local/include to the default include search path, since
1464 we were already searching /usr/local/lib for libraries.
1465
1466And various minor fixes and documentation updates.
1467
1468
