21 based on the file header, to match read_multi().
22
23 - re-work and add tests for def_guess_type(). def_guess_type() no

73 creation.
74
75 - Imager::Font->new now produces better error messages for the T1
76 engine.
77
6e938c74
TC
78 - the font has_chars() method now returns perl's true and false
79 values in list context rather than integers, which should be more
80 efficient.

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

6d5c85a2 110==============
a7e32beb
TC
111
112 - add simple tests for the Imager::Test test_image generators
113
6d5c85a2
TC
114 - io_glue I/O buffering re-work:
115
116 - reorganize io_glue to do it's own buffering by default
117
118 - the unbuffered functions are available as i_io_raw_read() (or
119 raw_read() from perl) etc but are not recommended for typical
120 use.
121
122 - use the new i_io_peekn() when checking for file magic to avoid
123 seek, allowing Imager to detect the file type and read the file
124 from an unseekable stream (for formats that don't use random
125 access)
126
127 - added several new I/O layer API functions.
128
129 - fix the TGA performance problem, most noticably on Win32
130 https://rt.cpan.org/Ticket/Display.html?id=70037
131
132 - TIFF now uses wrapper functions of the correct types to avoid casts
133 https://rt.cpan.org/Ticket/Display.html?id=69912
134
135 - the callback IO object did its own buffering, controlled by the
136 maxbuffer parameter supplied to the read() and write() methods.
137 This buffering has been removed, to avoid redundancy with the
138 common io_glue buffering. This also avoids a bug in that code
139 which could rarely pass a zero length to the read callback and
140 then panic about the result.
141
142 - the callback IO object now tests the result of calling the close
143 callback, which should return true for success.
144
145 - the PNM reader did its own buffering. This buffering has been
146 removed to avoid redundancy with the common io_glue buffering.
147
148 - previously the read handlers for fd and callback I/O layers would
149 call the underlying interface (POSIX read or your supplied callback)
150 until it filled the buffer. It now only makes one call.
151
152 - added public constructors for I/O layer objects (see Imager::IO)
153
154 - all core file handlers now use the i_io_foo() wrappers to gain
155 access to buffered I/O rather than calling the I/O layer
156 callbacks directly.
157
158 - all core file handlers now check for error on close.
159
160 - Backward compatibility: if you hava custom file handlers, you can
161 use i_io_write() etc since they're available as macros in older
162 versions of Imager.
163
164 - eliminate the final remnants of io_glue_commit_types().
165
166 - bump IMAGER_API_VERSION, since the above may break assumptions.
167
168 - removed the long unused i_gen_reader() and i_gen_writer() utility
169 functions.

6ad7e4bc
TC
172===========
173
0c647c9a
TC
174The main changes in the release versus 0.84 are:
175
176 - on 64-bit systems, 64-bit types are consistently used for image
177 dimensions and co-ordinated, and for memory block sizes.
178
179 - handle IFD loops in TIFF files correctly. Previously this would
180 lead to an infinite loop.
181
6ad7e4bc
TC
182Bug fixes:
183
184 - fix the link in the getheight() entry in the method index

190favourable.
6b7197d0
TC
191
192Bug fixes:
193
194 - the image file limits set by set_file_limits() weren't being
195 checked when reading TIFF files.
196 https://rt.cpan.org/Ticket/Display.html?id=69915
197
5970bd39
TC
198 - Provide more information about file format module load errors on a
199 failed image file read() or write().
200 https://rt.cpan.org/Ticket/Display.html?id=69194
201
4ce3551c
TC
202 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
203 through TIFF images, since it checks for IFD loops.
204 https://rt.cpan.org/Ticket/Display.html?id=69914
205
a16bca6d
TC
206 - don't leak memory when out of range palette indexes are supplied to
207 setscanline().
208 https://rt.cpan.org/Ticket/Display.html?id=69242
209
210 - require a later version of CPAN::Meta to ensure JSON::PP and
211 CPAN::Meta::YAML are available.
212 https://rt.cpan.org/Ticket/Display.html?id=69008
213
ac575c5f
TC
214 - hoist the per-line calculations for the flines implementations, and
215 modernize the tests a bit.
216 https://rt.cpan.org/Ticket/Display.html?id=70126
217
86c8d19a
TC
218 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
219 them when available.

221
a3fd7df7
TC
222 - if t1lib failed to reinitialize it would be left as marked

229Imager 0.84_01 - 8 Aug 2011
230==============
231
232Development release as a sanity check for the types re-work.
8d14daab
TC
233
234Massive types re-work:
235
236 - the type used internally for pixel co-ordinates and image sizes is
237 now 64-bit on 64-bit platforms (at least sane ones).
238
239 - size_t is now used consistently for memory block sizes.
240
241 - since this changes the binary interface, the Imager API version has
242 been incremented. Any module that uses the API will need to be
243 rebuilt. In most cases that will be enough, but calls to any APIs
244 that take a pointer to image sizes may need source changes.
245
246 - you should be able to create very large images on 64-bit systems,
247 if you have enough memory. Successfully created a 32768 x 49192 x
248 3 channel image, filled with a tiled image and scaled it. The
249 unscaled image was also successfully saved to a JPEG.
250
251 - check the image size before attempting to write BMP, GIF, JPEG,
252 PNG, SGI, TGA, TIFF images.
253
254 - correctly handle reading TGA images over 32767 pixels wide or tall.
255
256Incidental changes:
257
258 - the gif_left and gif_top tags are now clamped to non-negative
259 values when writing a GIF image.
260
261 - removed dead callback read/write code
262
263The default maximum memory size when reading files is now 1G.

266===========
267
268 - Imager no longer inherits from Exporter (unless you're running an
269 old, old perl.
270
92e9df65

TC
290 - convert colors to grayscale if the supplied (or generated) palette
291 contains only grays when performing error diffusion color
292 translation.
293 https://rt.cpan.org/Ticket/Display.html?id=68508
294
59c150a4
TC
295 - writing a paletted image to GIF wouldn't always use the colors
296 supplied (or generated, eg. via make_colors => "mono"), which was
297 confusing at best.
298 https://rt.cpan.org/Ticket/Display.html?id=67912
299
5b480b14
TC
300 - replace (imager|tony)@imager.perl.org in the doc, since I don't

TC
324 - compose() with the target, source or mask position off the top or
325 left of the target image didn't clip the source image correctly.
326 https://rt.cpan.org/Ticket/Display.html?id=67220
327
328 - compose() now returns a useful error message on a non-positive
329 opacity.
330
331 - compose.im now at 100% test coverage. (As opposed to, umm, much,
332 much less.)

TC
335===========
336
337Bug fixes:
338
339 - eliminate calls to i_has_format() from the test suite, since it's
340 no longer a useful way to check for file format support. Eliminate
341 i_has_format() from the functions exposed via XS.
342 https://rt.cpan.org/Ticket/Display.html?id=65863
343
7540f84a
TC
344 - eliminate calls to note(), which isn't in the (very old) version of
345 Test::More we have as a pre-requisite. note() is modern enough
346 that I don't feel a need to require a Test::More upgrade for it.
347 https://rt.cpan.org/Ticket/Display.html?id=65864
348
81984f30

359 downgrade the version in this file.
360 https://rt.cpan.org/Ticket/Display.html?id=66250
361
362 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
363 that option for the directories that would normally go in
364 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

440
2a2c791f
TC
441 - the convert() method now optimizes the case where all output
442 channels are either 0, sourced from a single input channel or 1.
443 This significantly speeds up presets like "addalpha", "green".

916 - rubthrough() now falls back to pasting when the source doesn't have
917 an alpha channel. This effectively treats the source as having a
918 max alpha channel, the right thing to do.

925 defines them with respect to a translucent source and destination.
926 Added tests for translucent source and destination.

964 - some TGA images weren't being detected correctly as TGA images
965 https://rt.cpan.org/Ticket/Display.html?id=32925
966
967 - handling of the left-over bit for 16-bit/pixel TGA images has been
968 changed to match the behaviour of the GIMP. Previously the bit
969 being set was treated as an opaque pixel, but one user reported a
970 problem with loading such an image. I haven't been able to find any
971 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
972 I'll match it's behaviour. See issue 114913 in the GIMP's
973 bugzilla.

1339Imager 0.54 - 14 Sep 2006
1340===========
1341
1342This is primarily a feature release:
1343
1344 - a new qtype value 'mixing' has been added to the scale()
1345 method. This is faster than 'normal', slower than 'preview'. This
1346 is based on the method used by pnmscale, and seems to produce less
1347 blurry results than normal.
1348 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1349
1350 - the rubthrough() method can now render onto images with an alpha
1351 channel.
1352 http://rt.cpan.org/Ticket/Display.html?id=20678
1353
1354 - the read_multi() method now falls back to calling doing a single
1355 image read via the read() method and write_multi() will now fall
1356 back to calling write() if a single image is supplied. This means
1357 you can simply call the read_multi() or write_multi() functions
1358 without having to check if the type is formatted by that method.
1359 http://rt.cpan.org/Ticket/Display.html?id=19457
1360 http://rt.cpan.org/Ticket/Display.html?id=19458
1361
1362 - the GIF loop extension can now be written. If you don't have
1363 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1364 should upgrade.
1365 http://rt.cpan.org/Ticket/Display.html?id=21185
1366
1367 - getscanline() and setscanline() can now read/write palette index
1368 based data from/to the image for paletted images, by setting type to
1369 'index'.
1370 http://rt.cpan.org/Ticket/Display.html?id=20338
1371
1372 - we no longer hassle you to disable GIF support
1373 http://rt.cpan.org/Ticket/Display.html?id=20687
1374
1375 - minor documentation fixes
1376
1377
1378Imager 0.53 - 26 Jul 2006
1379===========
1380
1381This is a bugfix release.
1382
1383Some test code was left in a code path not covered by the test
1384suite. A test was added to cover this code path and the test code was
1385removed.

1387
1388
1389Imager 0.52 - 25 Jul 2006
1390===========
1391
1392This is primarily a feature release, but contains a fair few bug
1393fixes, new features:
1394
1395 - ability to read and write MS Windows ICO and CUR files
1396
1397 - you can now add file format plugins to support new file formats
1398
1399 - add POD coverage tests
1400
1401 - setcolors() and addcolors() now accept color names and so on
1402 instead of requiring Imager::Color objects.
1403 http://rt.cpan.org/Ticket/Display.html?id=20056
1404
1405 - flood_fill() can now fill to a specified border color instead of
1406 just to the area the same color as the seed.
1407 http://rt.cpan.org/Ticket/Display.html?id=19618
1408
1409
1410Bug fixes:
1411
1412 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1413 calculating the advance width.
1414 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1415
1416 - bounding_box for the T1 driver wasn't including leading and
1417 trailing spaces in the bounding box as the other drivers did, it also
1418 produced strange results for empty strings or strings containing only
1419 spaces
1420
1421 - when reading CMYK jpeg images they were being transferred to the
1422 image object as is, producing a four channel image. It only looked ok
1423 due to an old still unfixed Photoshop bug. We now convert from the
1424 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1425 http://rt.cpan.org/Ticket/Display.html?id=20416
1426
1427 - reading a CYMK TIFF would result in a 4 channel image, reading any
1428 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1429 result in an error.
1430 http://rt.cpan.org/Ticket/Display.html?id=20415
1431
1432 - added /usr/local/include to the default include search path, since
1433 we were already searching /usr/local/lib for libraries.
1434
1435And various minor fixes and documentation updates.
1436
