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

31 - read() now uses $FORMATGUESS if it can't determine the file type
32 based on the file header, to match read_multi().
33
34 - re-work and add tests for def_guess_type(). def_guess_type() no
35 longer returns any random file extension as the file type.

84 it.
85
5efba0c6

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

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

6d5c85a2 130==============
a7e32beb
TC
131
132 - add simple tests for the Imager::Test test_image generators
133
6d5c85a2
TC
134 - io_glue I/O buffering re-work:
135
136 - reorganize io_glue to do it's own buffering by default
137
138 - the unbuffered functions are available as i_io_raw_read() (or
139 raw_read() from perl) etc but are not recommended for typical
140 use.
141
142 - use the new i_io_peekn() when checking for file magic to avoid
143 seek, allowing Imager to detect the file type and read the file
144 from an unseekable stream (for formats that don't use random
145 access)
146
147 - added several new I/O layer API functions.
148
149 - fix the TGA performance problem, most noticably on Win32
150 https://rt.cpan.org/Ticket/Display.html?id=70037
151
152 - TIFF now uses wrapper functions of the correct types to avoid casts
153 https://rt.cpan.org/Ticket/Display.html?id=69912
154
155 - the callback IO object did its own buffering, controlled by the
156 maxbuffer parameter supplied to the read() and write() methods.
157 This buffering has been removed, to avoid redundancy with the
158 common io_glue buffering. This also avoids a bug in that code
159 which could rarely pass a zero length to the read callback and
160 then panic about the result.
161
162 - the callback IO object now tests the result of calling the close
163 callback, which should return true for success.
164
165 - the PNM reader did its own buffering. This buffering has been
166 removed to avoid redundancy with the common io_glue buffering.
167
168 - previously the read handlers for fd and callback I/O layers would
169 call the underlying interface (POSIX read or your supplied callback)
170 until it filled the buffer. It now only makes one call.
171
172 - added public constructors for I/O layer objects (see Imager::IO)
173
174 - all core file handlers now use the i_io_foo() wrappers to gain
175 access to buffered I/O rather than calling the I/O layer
176 callbacks directly.
177
178 - all core file handlers now check for error on close.
179
180 - Backward compatibility: if you hava custom file handlers, you can
181 use i_io_write() etc since they're available as macros in older
182 versions of Imager.
183
184 - eliminate the final remnants of io_glue_commit_types().
185
186 - bump IMAGER_API_VERSION, since the above may break assumptions.
187
188 - removed the long unused i_gen_reader() and i_gen_writer() utility
189 functions.

TC
192===========
193
0c647c9a
TC
194The main changes in the release versus 0.84 are:
195
196 - on 64-bit systems, 64-bit types are consistently used for image
197 dimensions and co-ordinated, and for memory block sizes.
198
199 - handle IFD loops in TIFF files correctly. Previously this would
200 lead to an infinite loop.
201
6ad7e4bc
TC
202Bug fixes:
203
204 - fix the link in the getheight() entry in the method index

210favourable.
6b7197d0
TC
211
212Bug fixes:
213
214 - the image file limits set by set_file_limits() weren't being
215 checked when reading TIFF files.
216 https://rt.cpan.org/Ticket/Display.html?id=69915
217
5970bd39
TC
218 - Provide more information about file format module load errors on a
219 failed image file read() or write().
220 https://rt.cpan.org/Ticket/Display.html?id=69194
221
4ce3551c
TC
222 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
223 through TIFF images, since it checks for IFD loops.
224 https://rt.cpan.org/Ticket/Display.html?id=69914
225
a16bca6d
TC
226 - don't leak memory when out of range palette indexes are supplied to
227 setscanline().
228 https://rt.cpan.org/Ticket/Display.html?id=69242
229
230 - require a later version of CPAN::Meta to ensure JSON::PP and
231 CPAN::Meta::YAML are available.
232 https://rt.cpan.org/Ticket/Display.html?id=69008
233
ac575c5f
TC
234 - hoist the per-line calculations for the flines implementations, and
235 modernize the tests a bit.
236 https://rt.cpan.org/Ticket/Display.html?id=70126
237
86c8d19a
TC
238 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use

249Imager 0.84_01 - 8 Aug 2011
250==============
251
252Development release as a sanity check for the types re-work.
8d14daab
TC
253
254Massive types re-work:
255
256 - the type used internally for pixel co-ordinates and image sizes is
257 now 64-bit on 64-bit platforms (at least sane ones).
258
259 - size_t is now used consistently for memory block sizes.
260
261 - since this changes the binary interface, the Imager API version has
262 been incremented. Any module that uses the API will need to be
263 rebuilt. In most cases that will be enough, but calls to any APIs
264 that take a pointer to image sizes may need source changes.
265
266 - you should be able to create very large images on 64-bit systems,
267 if you have enough memory. Successfully created a 32768 x 49192 x
268 3 channel image, filled with a tiled image and scaled it. The
269 unscaled image was also successfully saved to a JPEG.
270
271 - check the image size before attempting to write BMP, GIF, JPEG,
272 PNG, SGI, TGA, TIFF images.
273
274 - correctly handle reading TGA images over 32767 pixels wide or tall.
275
276Incidental changes:
277
278 - the gif_left and gif_top tags are now clamped to non-negative
279 values when writing a GIF image.
280
281 - removed dead callback read/write code
282
283The default maximum memory size when reading files is now 1G.

289 old, old perl.
290

TC
294Bug fixes:

TC
310 - convert colors to grayscale if the supplied (or generated) palette
311 contains only grays when performing error diffusion color
312 translation.
313 https://rt.cpan.org/Ticket/Display.html?id=68508
314
59c150a4
TC
315 - writing a paletted image to GIF wouldn't always use the colors
316 supplied (or generated, eg. via make_colors => "mono"), which was
317 confusing at best.
318 https://rt.cpan.org/Ticket/Display.html?id=67912
319
5b480b14
TC
320 - replace (imager|tony)@imager.perl.org in the doc, since I don't

344 - compose() with the target, source or mask position off the top or
345 left of the target image didn't clip the source image correctly.
346 https://rt.cpan.org/Ticket/Display.html?id=67220
347
348 - compose() now returns a useful error message on a non-positive
349 opacity.
350
351 - compose.im now at 100% test coverage. (As opposed to, umm, much,
352 much less.)

TC
355===========
356
357Bug fixes:
358
359 - eliminate calls to i_has_format() from the test suite, since it's
360 no longer a useful way to check for file format support. Eliminate
361 i_has_format() from the functions exposed via XS.
362 https://rt.cpan.org/Ticket/Display.html?id=65863
363
7540f84a
TC
364 - eliminate calls to note(), which isn't in the (very old) version of
365 Test::More we have as a pre-requisite. note() is modern enough
366 that I don't feel a need to require a Test::More upgrade for it.
367 https://rt.cpan.org/Ticket/Display.html?id=65864
368
81984f30

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

921This release primarily contains changes to improve ease of use -
922rather than you having to convert images to the appropriate number of
923channels, Imager handles it internally. How to handle drawing colors
924and the default combine mode is a thornier problem left for some other
925release.

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

974 - mixing qtype scaling now sets all channels of a pixel to zero if

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

1005 - the old dynaload code used Mach API functions to load dynamic
1006 libraries on Mac OS X. These APIs have been deprecated in OS X
1007 10.5 and were causing some build problems.
1008 So henceforth Imager uses the dlopen() family of functions, and you
1009 will need version 10.3 or later of OS X.

1332 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1333
1334 - the gif_disposal and gif_user_input tags weren't being read from
1335 the file correctly
1336 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1337
1338 - gif.c was failing to build under MSVC
1339 http://rt.cpan.org/Ticket/Display.html?id=23922
1340
1341 - in some cases strings passed to the string() method were treated as
1342 terminated by NUL (chr 0)
1343 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1344
1345 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since

1361Imager 0.54 - 14 Sep 2006
1362===========
1363
1364This is primarily a feature release:
1365
1366 - a new qtype value 'mixing' has been added to the scale()
1367 method. This is faster than 'normal', slower than 'preview'. This
1368 is based on the method used by pnmscale, and seems to produce less
1369 blurry results than normal.
1370 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1371
1372 - the rubthrough() method can now render onto images with an alpha
1373 channel.
1374 http://rt.cpan.org/Ticket/Display.html?id=20678
1375
1376 - the read_multi() method now falls back to calling doing a single
1377 image read via the read() method and write_multi() will now fall
1378 back to calling write() if a single image is supplied. This means
1379 you can simply call the read_multi() or write_multi() functions
1380 without having to check if the type is formatted by that method.
1381 http://rt.cpan.org/Ticket/Display.html?id=19457
1382 http://rt.cpan.org/Ticket/Display.html?id=19458
1383
1384 - the GIF loop extension can now be written. If you don't have
1385 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1386 should upgrade.
1387 http://rt.cpan.org/Ticket/Display.html?id=21185
1388
1389 - getscanline() and setscanline() can now read/write palette index
1390 based data from/to the image for paletted images, by setting type to
1391 'index'.
1392 http://rt.cpan.org/Ticket/Display.html?id=20338
1393
1394 - we no longer hassle you to disable GIF support
1395 http://rt.cpan.org/Ticket/Display.html?id=20687
1396
1397 - minor documentation fixes
1398
1399
1400Imager 0.53 - 26 Jul 2006
1401===========
1402
1403This is a bugfix release.
1404
1405Some test code was left in a code path not covered by the test
1406suite. A test was added to cover this code path and the test code was
1407removed.

1410
1411Imager 0.52 - 25 Jul 2006
1412===========
1413
1414This is primarily a feature release, but contains a fair few bug
1415fixes, new features:
1416
1417 - ability to read and write MS Windows ICO and CUR files
1418
1419 - you can now add file format plugins to support new file formats
1420
1421 - add POD coverage tests
1422
1423 - setcolors() and addcolors() now accept color names and so on
1424 instead of requiring Imager::Color objects.
1425 http://rt.cpan.org/Ticket/Display.html?id=20056
1426
1427 - flood_fill() can now fill to a specified border color instead of
1428 just to the area the same color as the seed.
1429 http://rt.cpan.org/Ticket/Display.html?id=19618
1430
1431
1432Bug fixes:
1433
1434 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1435 calculating the advance width.
1436 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1437
1438 - bounding_box for the T1 driver wasn't including leading and
1439 trailing spaces in the bounding box as the other drivers did, it also
1440 produced strange results for empty strings or strings containing only
1441 spaces
1442
1443 - when reading CMYK jpeg images they were being transferred to the
1444 image object as is, producing a four channel image. It only looked ok
1445 due to an old still unfixed Photoshop bug. We now convert from the
1446 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1447 http://rt.cpan.org/Ticket/Display.html?id=20416
1448
1449 - reading a CYMK TIFF would result in a 4 channel image, reading any
1450 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1451 result in an error.
1452 http://rt.cpan.org/Ticket/Display.html?id=20415
1453
1454 - added /usr/local/include to the default include search path, since
1455 we were already searching /usr/local/lib for libraries.
1456
1457And various minor fixes and documentation updates.
1458
