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

31be6e9a 93Imager 0.85_01 - 10 Oct 2011
6d5c85a2 94==============
a7e32beb
TC
95
96 - add simple tests for the Imager::Test test_image generators
97
6d5c85a2
TC
98 - io_glue I/O buffering re-work:
99
100 - reorganize io_glue to do it's own buffering by default
101
102 - the unbuffered functions are available as i_io_raw_read() (or
103 raw_read() from perl) etc but are not recommended for typical
104 use.
105
106 - use the new i_io_peekn() when checking for file magic to avoid
107 seek, allowing Imager to detect the file type and read the file
108 from an unseekable stream (for formats that don't use random
109 access)
110
111 - added several new I/O layer API functions.
112
113 - fix the TGA performance problem, most noticably on Win32
114 https://rt.cpan.org/Ticket/Display.html?id=70037
115
116 - TIFF now uses wrapper functions of the correct types to avoid casts
117 https://rt.cpan.org/Ticket/Display.html?id=69912
118
119 - the callback IO object did its own buffering, controlled by the
120 maxbuffer parameter supplied to the read() and write() methods.
121 This buffering has been removed, to avoid redundancy with the
122 common io_glue buffering. This also avoids a bug in that code
123 which could rarely pass a zero length to the read callback and
124 then panic about the result.
125
126 - the callback IO object now tests the result of calling the close
127 callback, which should return true for success.
128
129 - the PNM reader did its own buffering. This buffering has been
130 removed to avoid redundancy with the common io_glue buffering.
131
132 - previously the read handlers for fd and callback I/O layers would
133 call the underlying interface (POSIX read or your supplied callback)
134 until it filled the buffer. It now only makes one call.
135
136 - added public constructors for I/O layer objects (see Imager::IO)
137
138 - all core file handlers now use the i_io_foo() wrappers to gain
139 access to buffered I/O rather than calling the I/O layer
140 callbacks directly.
141
142 - all core file handlers now check for error on close.
143
144 - Backward compatibility: if you hava custom file handlers, you can
145 use i_io_write() etc since they're available as macros in older
146 versions of Imager.
147
148 - eliminate the final remnants of io_glue_commit_types().
149
150 - bump IMAGER_API_VERSION, since the above may break assumptions.
151
152 - removed the long unused i_gen_reader() and i_gen_writer() utility
153 functions.

6ad7e4bc
TC
156===========
157
0c647c9a
TC
158The main changes in the release versus 0.84 are:
159
160 - on 64-bit systems, 64-bit types are consistently used for image
161 dimensions and co-ordinated, and for memory block sizes.
162
163 - handle IFD loops in TIFF files correctly. Previously this would
164 lead to an infinite loop.
165
6ad7e4bc
TC
166Bug fixes:
167
168 - fix the link in the getheight() entry in the method index
169

172
173Development release, this will become 0.85 if CPAN testers is
174favourable.
6b7197d0
TC
175
176Bug fixes:
177
178 - the image file limits set by set_file_limits() weren't being
179 checked when reading TIFF files.
180 https://rt.cpan.org/Ticket/Display.html?id=69915
181
5970bd39
TC
182 - Provide more information about file format module load errors on a
183 failed image file read() or write().
184 https://rt.cpan.org/Ticket/Display.html?id=69194
185
4ce3551c
TC
186 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
187 through TIFF images, since it checks for IFD loops.
188 https://rt.cpan.org/Ticket/Display.html?id=69914
189
a16bca6d
TC
190 - don't leak memory when out of range palette indexes are supplied to
191 setscanline().
192 https://rt.cpan.org/Ticket/Display.html?id=69242
193
194 - require a later version of CPAN::Meta to ensure JSON::PP and
195 CPAN::Meta::YAML are available.
196 https://rt.cpan.org/Ticket/Display.html?id=69008
197
ac575c5f
TC
198 - hoist the per-line calculations for the flines implementations, and
199 modernize the tests a bit.
200 https://rt.cpan.org/Ticket/Display.html?id=70126
201
86c8d19a
TC
202 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
203 them when available.
204 https://rt.cpan.org/Ticket/Display.html?id=69147
205
a3fd7df7
TC
206 - if t1lib failed to reinitialize it would be left as marked
207 initialized.

213Imager 0.84_01 - 8 Aug 2011
214==============
215
216Development release as a sanity check for the types re-work.
8d14daab
TC
217
218Massive types re-work:
219
220 - the type used internally for pixel co-ordinates and image sizes is
221 now 64-bit on 64-bit platforms (at least sane ones).
222
223 - size_t is now used consistently for memory block sizes.
224
225 - since this changes the binary interface, the Imager API version has
226 been incremented. Any module that uses the API will need to be
227 rebuilt. In most cases that will be enough, but calls to any APIs
228 that take a pointer to image sizes may need source changes.
229
230 - you should be able to create very large images on 64-bit systems,
231 if you have enough memory. Successfully created a 32768 x 49192 x
232 3 channel image, filled with a tiled image and scaled it. The
233 unscaled image was also successfully saved to a JPEG.
234
235 - check the image size before attempting to write BMP, GIF, JPEG,
236 PNG, SGI, TGA, TIFF images.
237
238 - correctly handle reading TGA images over 32767 pixels wide or tall.
239
240Incidental changes:
241
242 - the gif_left and gif_top tags are now clamped to non-negative
243 values when writing a GIF image.
244
245 - removed dead callback read/write code
246
247The default maximum memory size when reading files is now 1G.

TC
250===========
251
252 - Imager no longer inherits from Exporter (unless you're running an
253 old, old perl.
254
92e9df65
TC
255 - Imager can now write progressive JPEGs (it could always read them).

257
10ea52a3
TC
258Bug fixes:
259

273
6d068d36
TC
274 - convert colors to grayscale if the supplied (or generated) palette
275 contains only grays when performing error diffusion color
276 translation.
277 https://rt.cpan.org/Ticket/Display.html?id=68508
278
59c150a4
TC
279 - writing a paletted image to GIF wouldn't always use the colors
280 supplied (or generated, eg. via make_colors => "mono"), which was
281 confusing at best.
282 https://rt.cpan.org/Ticket/Display.html?id=67912
283
5b480b14
TC
284 - replace (imager|tony)@imager.perl.org in the doc, since I don't

deb1a916
TC
301
302Bug fixes:
303
304 - Imager::Font::T1 incorrectly checked for absolute filename under
305 Win32. Thanks to kmx for the report and fix.
306 https://rt.cpan.org/Ticket/Display.html?id=67963
307
618a3282
TC
308 - compose() with the target, source or mask position off the top or
309 left of the target image didn't clip the source image correctly.
310 https://rt.cpan.org/Ticket/Display.html?id=67220
311
312 - compose() now returns a useful error message on a non-positive
313 opacity.
314
315 - compose.im now at 100% test coverage. (As opposed to, umm, much,
316 much less.)

2368cfec
TC
319===========
320
321Bug fixes:
322
323 - eliminate calls to i_has_format() from the test suite, since it's
324 no longer a useful way to check for file format support. Eliminate
325 i_has_format() from the functions exposed via XS.
326 https://rt.cpan.org/Ticket/Display.html?id=65863
327
7540f84a
TC
328 - eliminate calls to note(), which isn't in the (very old) version of
329 Test::More we have as a pre-requisite. note() is modern enough
330 that I don't feel a need to require a Test::More upgrade for it.
331 https://rt.cpan.org/Ticket/Display.html?id=65864
332
81984f30

333 - skip the threads tests on Test::More 2.00_*

342 - increase the version of Imager::Font::Type1 so that upgrades don't
343 downgrade the version in this file.
344 https://rt.cpan.org/Ticket/Display.html?id=66250
345
346 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
347 that option for the directories that would normally go in
348 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

424
2a2c791f
TC
425 - the convert() method now optimizes the case where all output
426 channels are either 0, sourced from a single input channel or 1.
427 This significantly speeds up presets like "addalpha", "green".

948 - some TGA images weren't being detected correctly as TGA images
949 https://rt.cpan.org/Ticket/Display.html?id=32925
950
951 - handling of the left-over bit for 16-bit/pixel TGA images has been
952 changed to match the behaviour of the GIMP. Previously the bit
953 being set was treated as an opaque pixel, but one user reported a
954 problem with loading such an image. I haven't been able to find any
955 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
956 I'll match it's behaviour. See issue 114913 in the GIMP's
957 bugzilla.

1279
1280Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1281
1282There is one new feature:

1286 http://rt.cpan.org/Ticket/Display.html?id=22166

1289
1290 - the string() method would not output the string "0"
1291 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1292
1293 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1294 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1295
1296 - the gif_disposal and gif_user_input tags weren't being read from
1297 the file correctly
1298 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1299
1300 - gif.c was failing to build under MSVC
1301 http://rt.cpan.org/Ticket/Display.html?id=23922
1302
1303 - in some cases strings passed to the string() method were treated as
1304 terminated by NUL (chr 0)
1305 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1306
1307 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1308 that's the default build name for zlib on Win32.
1309 http://rt.cpan.org/Ticket/Display.html?id=23064
1310
1311 - search $Config{incpath} for headers too, which we should have been
1312 doing all along.
1313
1314Win32 font driver fixes:
1315
1316 - the global descent value from bounding box was the wrong sign
1317 http://www.cpanforum.com/threads/3276
1318

1322
1323Imager 0.54 - 14 Sep 2006
1324===========
1325
1326This is primarily a feature release:
1327
1328 - a new qtype value 'mixing' has been added to the scale()
1329 method. This is faster than 'normal', slower than 'preview'. This
1330 is based on the method used by pnmscale, and seems to produce less
1331 blurry results than normal.
1332 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1333
1334 - the rubthrough() method can now render onto images with an alpha
1335 channel.
1336 http://rt.cpan.org/Ticket/Display.html?id=20678
1337
1338 - the read_multi() method now falls back to calling doing a single
1339 image read via the read() method and write_multi() will now fall
1340 back to calling write() if a single image is supplied. This means
1341 you can simply call the read_multi() or write_multi() functions
1342 without having to check if the type is formatted by that method.

1345
1346 - the GIF loop extension can now be written. If you don't have
1347 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1348 should upgrade.
1349 http://rt.cpan.org/Ticket/Display.html?id=21185
1350
1351 - getscanline() and setscanline() can now read/write palette index
1352 based data from/to the image for paletted images, by setting type to
1353 'index'.
1354 http://rt.cpan.org/Ticket/Display.html?id=20338
1355
1356 - we no longer hassle you to disable GIF support

1363===========
1364
1365This is a bugfix release.
1366
1367Some test code was left in a code path not covered by the test

1373Imager 0.52 - 25 Jul 2006
1374===========
1375
1376This is primarily a feature release, but contains a fair few bug
1377fixes, new features:
1378
1379 - ability to read and write MS Windows ICO and CUR files
1380
1381 - you can now add file format plugins to support new file formats
1382
1383 - add POD coverage tests
1384
1385 - setcolors() and addcolors() now accept color names and so on
1386 instead of requiring Imager::Color objects.
1387 http://rt.cpan.org/Ticket/Display.html?id=20056
1388
1389 - flood_fill() can now fill to a specified border color instead of
1390 just to the area the same color as the seed.
1391 http://rt.cpan.org/Ticket/Display.html?id=19618
1392
1393
1394Bug fixes:
1395
1396 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1397 calculating the advance width.
1398 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1399
1400 - bounding_box for the T1 driver wasn't including leading and
1401 trailing spaces in the bounding box as the other drivers did, it also
1402 produced strange results for empty strings or strings containing only
1403 spaces
1404
1405 - when reading CMYK jpeg images they were being transferred to the
1406 image object as is, producing a four channel image. It only looked ok
1407 due to an old still unfixed Photoshop bug. We now convert from the
1408 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1409 http://rt.cpan.org/Ticket/Display.html?id=20416
1410
1411 - reading a CYMK TIFF would result in a 4 channel image, reading any
1412 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1413 result in an error.
1414 http://rt.cpan.org/Ticket/Display.html?id=20415
1415
1416 - added /usr/local/include to the default include search path, since
1417 we were already searching /usr/local/lib for libraries.
1418
1419And various minor fixes and documentation updates.
