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

31be6e9a 103Imager 0.85_01 - 10 Oct 2011
6d5c85a2 104==============
a7e32beb
TC
105
106 - add simple tests for the Imager::Test test_image generators
107
6d5c85a2
TC
108 - io_glue I/O buffering re-work:
109
110 - reorganize io_glue to do it's own buffering by default
111
112 - the unbuffered functions are available as i_io_raw_read() (or
113 raw_read() from perl) etc but are not recommended for typical
114 use.
115
116 - use the new i_io_peekn() when checking for file magic to avoid
117 seek, allowing Imager to detect the file type and read the file
118 from an unseekable stream (for formats that don't use random
119 access)
120
121 - added several new I/O layer API functions.
122
123 - fix the TGA performance problem, most noticably on Win32
124 https://rt.cpan.org/Ticket/Display.html?id=70037
125
126 - TIFF now uses wrapper functions of the correct types to avoid casts
127 https://rt.cpan.org/Ticket/Display.html?id=69912
128
129 - the callback IO object did its own buffering, controlled by the
130 maxbuffer parameter supplied to the read() and write() methods.
131 This buffering has been removed, to avoid redundancy with the
132 common io_glue buffering. This also avoids a bug in that code
133 which could rarely pass a zero length to the read callback and
134 then panic about the result.
135
136 - the callback IO object now tests the result of calling the close
137 callback, which should return true for success.
138
139 - the PNM reader did its own buffering. This buffering has been
140 removed to avoid redundancy with the common io_glue buffering.
141
142 - previously the read handlers for fd and callback I/O layers would
143 call the underlying interface (POSIX read or your supplied callback)
144 until it filled the buffer. It now only makes one call.
145
146 - added public constructors for I/O layer objects (see Imager::IO)
147
148 - all core file handlers now use the i_io_foo() wrappers to gain
149 access to buffered I/O rather than calling the I/O layer
150 callbacks directly.
151
152 - all core file handlers now check for error on close.
153
154 - Backward compatibility: if you hava custom file handlers, you can
155 use i_io_write() etc since they're available as macros in older
156 versions of Imager.
157
158 - eliminate the final remnants of io_glue_commit_types().
159
160 - bump IMAGER_API_VERSION, since the above may break assumptions.
161
162 - removed the long unused i_gen_reader() and i_gen_writer() utility
163 functions.

6ad7e4bc
TC
166===========
167
0c647c9a
TC
168The main changes in the release versus 0.84 are:
169
170 - on 64-bit systems, 64-bit types are consistently used for image
171 dimensions and co-ordinated, and for memory block sizes.
172
173 - handle IFD loops in TIFF files correctly. Previously this would
174 lead to an infinite loop.
175
6ad7e4bc
TC
176Bug fixes:
177
178 - fix the link in the getheight() entry in the method index

184favourable.
6b7197d0
TC
185
186Bug fixes:
187
188 - the image file limits set by set_file_limits() weren't being
189 checked when reading TIFF files.
190 https://rt.cpan.org/Ticket/Display.html?id=69915
191
5970bd39
TC
192 - Provide more information about file format module load errors on a
193 failed image file read() or write().
194 https://rt.cpan.org/Ticket/Display.html?id=69194
195
4ce3551c
TC
196 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
197 through TIFF images, since it checks for IFD loops.
198 https://rt.cpan.org/Ticket/Display.html?id=69914
199
a16bca6d
TC
200 - don't leak memory when out of range palette indexes are supplied to
201 setscanline().
202 https://rt.cpan.org/Ticket/Display.html?id=69242
203
204 - require a later version of CPAN::Meta to ensure JSON::PP and
205 CPAN::Meta::YAML are available.
206 https://rt.cpan.org/Ticket/Display.html?id=69008
207
ac575c5f
TC
208 - hoist the per-line calculations for the flines implementations, and
209 modernize the tests a bit.
210 https://rt.cpan.org/Ticket/Display.html?id=70126
211
86c8d19a
TC
212 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
213 them when available.
214 https://rt.cpan.org/Ticket/Display.html?id=69147
215
a3fd7df7
TC
216 - if t1lib failed to reinitialize it would be left as marked

223Imager 0.84_01 - 8 Aug 2011
224==============
225
226Development release as a sanity check for the types re-work.
8d14daab
TC
227
228Massive types re-work:
229
230 - the type used internally for pixel co-ordinates and image sizes is
231 now 64-bit on 64-bit platforms (at least sane ones).
232
233 - size_t is now used consistently for memory block sizes.
234
235 - since this changes the binary interface, the Imager API version has
236 been incremented. Any module that uses the API will need to be
237 rebuilt. In most cases that will be enough, but calls to any APIs
238 that take a pointer to image sizes may need source changes.
239
240 - you should be able to create very large images on 64-bit systems,
241 if you have enough memory. Successfully created a 32768 x 49192 x
242 3 channel image, filled with a tiled image and scaled it. The
243 unscaled image was also successfully saved to a JPEG.
244
245 - check the image size before attempting to write BMP, GIF, JPEG,
246 PNG, SGI, TGA, TIFF images.
247
248 - correctly handle reading TGA images over 32767 pixels wide or tall.
249
250Incidental changes:
251
252 - the gif_left and gif_top tags are now clamped to non-negative
253 values when writing a GIF image.
254
255 - removed dead callback read/write code
256
257The default maximum memory size when reading files is now 1G.

TC
260===========
261
262 - Imager no longer inherits from Exporter (unless you're running an
263 old, old perl.
264
92e9df65
TC
265 - Imager can now write progressive JPEGs (it could always read them).

TC
268Bug fixes:

283
6d068d36
TC
284 - convert colors to grayscale if the supplied (or generated) palette
285 contains only grays when performing error diffusion color
286 translation.
287 https://rt.cpan.org/Ticket/Display.html?id=68508
288
59c150a4
TC
289 - writing a paletted image to GIF wouldn't always use the colors
290 supplied (or generated, eg. via make_colors => "mono"), which was
291 confusing at best.
292 https://rt.cpan.org/Ticket/Display.html?id=67912
293
5b480b14
TC
294 - replace (imager|tony)@imager.perl.org in the doc, since I don't

TC
318 - compose() with the target, source or mask position off the top or
319 left of the target image didn't clip the source image correctly.
320 https://rt.cpan.org/Ticket/Display.html?id=67220
321
322 - compose() now returns a useful error message on a non-positive
323 opacity.
324
325 - compose.im now at 100% test coverage. (As opposed to, umm, much,
326 much less.)

2368cfec
TC
329===========
330
331Bug fixes:
332
333 - eliminate calls to i_has_format() from the test suite, since it's
334 no longer a useful way to check for file format support. Eliminate
335 i_has_format() from the functions exposed via XS.
336 https://rt.cpan.org/Ticket/Display.html?id=65863
337
7540f84a
TC
338 - eliminate calls to note(), which isn't in the (very old) version of
339 Test::More we have as a pre-requisite. note() is modern enough
340 that I don't feel a need to require a Test::More upgrade for it.
341 https://rt.cpan.org/Ticket/Display.html?id=65864
342

353 downgrade the version in this file.
354 https://rt.cpan.org/Ticket/Display.html?id=66250
355
356 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
357 that option for the directories that would normally go in
358 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

422 - make the default color map build algorithm "mediancut". This
423 changes the default color map builder for writing GIFs back to what

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

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

1339 method. This is faster than 'normal', slower than 'preview'. This
1340 is based on the method used by pnmscale, and seems to produce less
1341 blurry results than normal.
1342 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1343
1344 - the rubthrough() method can now render onto images with an alpha
1345 channel.
1346 http://rt.cpan.org/Ticket/Display.html?id=20678
1347
1348 - the read_multi() method now falls back to calling doing a single
1349 image read via the read() method and write_multi() will now fall
1350 back to calling write() if a single image is supplied. This means
1351 you can simply call the read_multi() or write_multi() functions
1352 without having to check if the type is formatted by that method.

1354 http://rt.cpan.org/Ticket/Display.html?id=19458
1355
1356 - the GIF loop extension can now be written. If you don't have
1357 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1358 should upgrade.
1359 http://rt.cpan.org/Ticket/Display.html?id=21185
1360
1361 - getscanline() and setscanline() can now read/write palette index
1362 based data from/to the image for paletted images, by setting type to
1363 'index'.
1364 http://rt.cpan.org/Ticket/Display.html?id=20338
1365
1366 - we no longer hassle you to disable GIF support

1369 - minor documentation fixes

1372Imager 0.53 - 26 Jul 2006
1373===========
1374
1375This is a bugfix release.
1376
1377Some test code was left in a code path not covered by the test
1378suite. A test was added to cover this code path and the test code was
1379removed.

1383Imager 0.52 - 25 Jul 2006
1384===========
1385
1386This is primarily a feature release, but contains a fair few bug
1387fixes, new features:
1388
1389 - ability to read and write MS Windows ICO and CUR files
1390
1391 - you can now add file format plugins to support new file formats
1392
1393 - add POD coverage tests
1394
1395 - setcolors() and addcolors() now accept color names and so on
1396 instead of requiring Imager::Color objects.
1397 http://rt.cpan.org/Ticket/Display.html?id=20056
1398
1399 - flood_fill() can now fill to a specified border color instead of
1400 just to the area the same color as the seed.
1401 http://rt.cpan.org/Ticket/Display.html?id=19618
1402
1403
1404Bug fixes:
1405
1406 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1407 calculating the advance width.
1408 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1409
1410 - bounding_box for the T1 driver wasn't including leading and
1411 trailing spaces in the bounding box as the other drivers did, it also
1412 produced strange results for empty strings or strings containing only
1413 spaces
1414
1415 - when reading CMYK jpeg images they were being transferred to the
1416 image object as is, producing a four channel image. It only looked ok
1417 due to an old still unfixed Photoshop bug. We now convert from the
1418 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1419 http://rt.cpan.org/Ticket/Display.html?id=20416
1420
1421 - reading a CYMK TIFF would result in a 4 channel image, reading any
1422 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1423 result in an error.
1424 http://rt.cpan.org/Ticket/Display.html?id=20415
1425
1426 - added /usr/local/include to the default include search path, since
1427 we were already searching /usr/local/lib for libraries.
1428
1429And various minor fixes and documentation updates.
