44 based on the file header, to match read_multi().
45

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

6d5c85a2 142==============
a7e32beb
TC
143
144 - add simple tests for the Imager::Test test_image generators
145
6d5c85a2
TC
146 - io_glue I/O buffering re-work:
147
148 - reorganize io_glue to do it's own buffering by default
149
150 - the unbuffered functions are available as i_io_raw_read() (or
151 raw_read() from perl) etc but are not recommended for typical
152 use.
153
154 - use the new i_io_peekn() when checking for file magic to avoid
155 seek, allowing Imager to detect the file type and read the file
156 from an unseekable stream (for formats that don't use random
157 access)
158
159 - added several new I/O layer API functions.
160
161 - fix the TGA performance problem, most noticably on Win32
162 https://rt.cpan.org/Ticket/Display.html?id=70037
163
164 - TIFF now uses wrapper functions of the correct types to avoid casts
165 https://rt.cpan.org/Ticket/Display.html?id=69912
166
167 - the callback IO object did its own buffering, controlled by the
168 maxbuffer parameter supplied to the read() and write() methods.
169 This buffering has been removed, to avoid redundancy with the
170 common io_glue buffering. This also avoids a bug in that code
171 which could rarely pass a zero length to the read callback and
172 then panic about the result.
173
174 - the callback IO object now tests the result of calling the close
175 callback, which should return true for success.
176
177 - the PNM reader did its own buffering. This buffering has been
178 removed to avoid redundancy with the common io_glue buffering.
179
180 - previously the read handlers for fd and callback I/O layers would
181 call the underlying interface (POSIX read or your supplied callback)
182 until it filled the buffer. It now only makes one call.
183
184 - added public constructors for I/O layer objects (see Imager::IO)
185
186 - all core file handlers now use the i_io_foo() wrappers to gain
187 access to buffered I/O rather than calling the I/O layer
188 callbacks directly.
189
190 - all core file handlers now check for error on close.
191
192 - Backward compatibility: if you hava custom file handlers, you can
193 use i_io_write() etc since they're available as macros in older
194 versions of Imager.
195
196 - eliminate the final remnants of io_glue_commit_types().
197
198 - bump IMAGER_API_VERSION, since the above may break assumptions.
199
200 - removed the long unused i_gen_reader() and i_gen_writer() utility
201 functions.

TC
204===========
205
0c647c9a
TC
206The main changes in the release versus 0.84 are:
207
208 - on 64-bit systems, 64-bit types are consistently used for image
209 dimensions and co-ordinated, and for memory block sizes.
210
211 - handle IFD loops in TIFF files correctly. Previously this would
212 lead to an infinite loop.
213
6ad7e4bc
TC
214Bug fixes:

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

229
5970bd39
TC
230 - Provide more information about file format module load errors on a
231 failed image file read() or write().
232 https://rt.cpan.org/Ticket/Display.html?id=69194
233
4ce3551c
TC
234 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
235 through TIFF images, since it checks for IFD loops.
236 https://rt.cpan.org/Ticket/Display.html?id=69914
237
a16bca6d
TC
238 - don't leak memory when out of range palette indexes are supplied to
239 setscanline().
240 https://rt.cpan.org/Ticket/Display.html?id=69242
241
242 - require a later version of CPAN::Meta to ensure JSON::PP and
243 CPAN::Meta::YAML are available.
244 https://rt.cpan.org/Ticket/Display.html?id=69008
245

261Imager 0.84_01 - 8 Aug 2011
262==============
263
264Development release as a sanity check for the types re-work.
8d14daab
TC
265
266Massive types re-work:
267
268 - the type used internally for pixel co-ordinates and image sizes is
269 now 64-bit on 64-bit platforms (at least sane ones).
270
271 - size_t is now used consistently for memory block sizes.
272
273 - since this changes the binary interface, the Imager API version has
274 been incremented. Any module that uses the API will need to be
275 rebuilt. In most cases that will be enough, but calls to any APIs
276 that take a pointer to image sizes may need source changes.
277
278 - you should be able to create very large images on 64-bit systems,
279 if you have enough memory. Successfully created a 32768 x 49192 x
280 3 channel image, filled with a tiled image and scaled it. The
281 unscaled image was also successfully saved to a JPEG.
282
283 - check the image size before attempting to write BMP, GIF, JPEG,
284 PNG, SGI, TGA, TIFF images.
285
286 - correctly handle reading TGA images over 32767 pixels wide or tall.
287
288Incidental changes:
289
290 - the gif_left and gif_top tags are now clamped to non-negative
291 values when writing a GIF image.
292
293 - removed dead callback read/write code
294
295The default maximum memory size when reading files is now 1G.

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

367===========

370
371 - eliminate calls to i_has_format() from the test suite, since it's

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

393
394 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
395 that option for the directories that would normally go in

916 resulting in a SIGSEGV when attempting to scale an image to a size
917 too large to fit in memory. This is a NULL pointer access issue,
918 not a buffer overflow.
919 Added a check for the failure.
920 scale_calculate() (and hence scale()) will now fail if any of the
921 scale size parameters are a reference.

933This release primarily contains changes to improve ease of use -
934rather than you having to convert images to the appropriate number of
935channels, Imager handles it internally. How to handle drawing colors
936and the default combine mode is a thornier problem left for some other
937release.

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

1000
1001 - handling of the left-over bit for 16-bit/pixel TGA images has been
1002 changed to match the behaviour of the GIMP. Previously the bit
1003 being set was treated as an opaque pixel, but one user reported a
1004 problem with loading such an image. I haven't been able to find any
1005 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1006 I'll match it's behaviour. See issue 114913 in the GIMP's
1007 bugzilla.

1017 - the old dynaload code used Mach API functions to load dynamic
1018 libraries on Mac OS X. These APIs have been deprecated in OS X
1019 10.5 and were causing some build problems.

1021 will need version 10.3 or later of OS X.

1334 - the Win32 font driver now supports UTF8 (RT 22166)
1335 http://www.cpanforum.com/threads/3276
1336 http://rt.cpan.org/Ticket/Display.html?id=22166
1337
1338Several bugs were fixed:
1339
1340 - the string() method would not output the string "0"
1341 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1342
1343 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1344 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1345
1346 - the gif_disposal and gif_user_input tags weren't being read from
1347 the file correctly
1348 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1349
1350 - gif.c was failing to build under MSVC
1351 http://rt.cpan.org/Ticket/Display.html?id=23922
1352
1353 - in some cases strings passed to the string() method were treated as
1354 terminated by NUL (chr 0)
1355 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1356
1357 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1358 that's the default build name for zlib on Win32.
1359 http://rt.cpan.org/Ticket/Display.html?id=23064
1360
1361 - search $Config{incpath} for headers too, which we should have been
1362 doing all along.
1363
1364Win32 font driver fixes:
1365
1366 - the global descent value from bounding box was the wrong sign
1367 http://www.cpanforum.com/threads/3276
1368
1369 - if the first or last glyph overflowed the left or right side of the
1370 advance width they would be clipped
1371
1372
1373Imager 0.54 - 14 Sep 2006
1374===========
1375
1376This is primarily a feature release:
1377
1378 - a new qtype value 'mixing' has been added to the scale()
1379 method. This is faster than 'normal', slower than 'preview'. This
1380 is based on the method used by pnmscale, and seems to produce less
1381 blurry results than normal.
1382 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1383
1384 - the rubthrough() method can now render onto images with an alpha
1385 channel.
1386 http://rt.cpan.org/Ticket/Display.html?id=20678
1387
1388 - the read_multi() method now falls back to calling doing a single
1389 image read via the read() method and write_multi() will now fall
1390 back to calling write() if a single image is supplied. This means
1391 you can simply call the read_multi() or write_multi() functions
1392 without having to check if the type is formatted by that method.
1393 http://rt.cpan.org/Ticket/Display.html?id=19457
1394 http://rt.cpan.org/Ticket/Display.html?id=19458
1395
1396 - the GIF loop extension can now be written. If you don't have
1397 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1398 should upgrade.
1399 http://rt.cpan.org/Ticket/Display.html?id=21185
1400
1401 - getscanline() and setscanline() can now read/write palette index
1402 based data from/to the image for paletted images, by setting type to
1403 'index'.
1404 http://rt.cpan.org/Ticket/Display.html?id=20338
1405
1406 - we no longer hassle you to disable GIF support
1407 http://rt.cpan.org/Ticket/Display.html?id=20687
1408
1409 - minor documentation fixes
1410
1411
1412Imager 0.53 - 26 Jul 2006
1413===========
1414
1415This is a bugfix release.
1416
1417Some test code was left in a code path not covered by the test
1418suite. A test was added to cover this code path and the test code was
1419removed.
1420http://rt.cpan.org/Public/Bug/Display.html?id=20705
1421
1422
1423Imager 0.52 - 25 Jul 2006
1424===========
1425
1426This is primarily a feature release, but contains a fair few bug
1427fixes, new features:
1428
1429 - ability to read and write MS Windows ICO and CUR files
1430
1431 - you can now add file format plugins to support new file formats
1432
1433 - add POD coverage tests
1434
1435 - setcolors() and addcolors() now accept color names and so on
1436 instead of requiring Imager::Color objects.
1437 http://rt.cpan.org/Ticket/Display.html?id=20056
1438
1439 - flood_fill() can now fill to a specified border color instead of
1440 just to the area the same color as the seed.
1441 http://rt.cpan.org/Ticket/Display.html?id=19618
1442
1443
1444Bug fixes:
1445
1446 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1447 calculating the advance width.
1448 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1449
1450 - bounding_box for the T1 driver wasn't including leading and
1451 trailing spaces in the bounding box as the other drivers did, it also
1452 produced strange results for empty strings or strings containing only
1453 spaces
1454
1455 - when reading CMYK jpeg images they were being transferred to the
1456 image object as is, producing a four channel image. It only looked ok
1457 due to an old still unfixed Photoshop bug. We now convert from the
1458 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1459 http://rt.cpan.org/Ticket/Display.html?id=20416
1460
1461 - reading a CYMK TIFF would result in a 4 channel image, reading any
1462 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1463 result in an error.
1464 http://rt.cpan.org/Ticket/Display.html?id=20415
1465
1466 - added /usr/local/include to the default include search path, since
1467 we were already searching /usr/local/lib for libraries.
1468
1469And various minor fixes and documentation updates.
1470
1471

1478
1479 - fix mis-processing of the src_maxx and src_maxy parameters of the
