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

31be6e9a 90Imager 0.85_01 - 10 Oct 2011
6d5c85a2 91==============
a7e32beb
TC
92
93 - add simple tests for the Imager::Test test_image generators
94
6d5c85a2
TC
95 - io_glue I/O buffering re-work:
96
97 - reorganize io_glue to do it's own buffering by default
98
99 - the unbuffered functions are available as i_io_raw_read() (or
100 raw_read() from perl) etc but are not recommended for typical
101 use.
102
103 - use the new i_io_peekn() when checking for file magic to avoid
104 seek, allowing Imager to detect the file type and read the file
105 from an unseekable stream (for formats that don't use random
106 access)
107
108 - added several new I/O layer API functions.
109
110 - fix the TGA performance problem, most noticably on Win32
111 https://rt.cpan.org/Ticket/Display.html?id=70037
112
113 - TIFF now uses wrapper functions of the correct types to avoid casts
114 https://rt.cpan.org/Ticket/Display.html?id=69912
115
116 - the callback IO object did its own buffering, controlled by the
117 maxbuffer parameter supplied to the read() and write() methods.
118 This buffering has been removed, to avoid redundancy with the
119 common io_glue buffering. This also avoids a bug in that code
120 which could rarely pass a zero length to the read callback and
121 then panic about the result.
122
123 - the callback IO object now tests the result of calling the close
124 callback, which should return true for success.
125
126 - the PNM reader did its own buffering. This buffering has been
127 removed to avoid redundancy with the common io_glue buffering.
128
129 - previously the read handlers for fd and callback I/O layers would
130 call the underlying interface (POSIX read or your supplied callback)
131 until it filled the buffer. It now only makes one call.
132
133 - added public constructors for I/O layer objects (see Imager::IO)
134
135 - all core file handlers now use the i_io_foo() wrappers to gain
136 access to buffered I/O rather than calling the I/O layer
137 callbacks directly.
138
139 - all core file handlers now check for error on close.
140
141 - Backward compatibility: if you hava custom file handlers, you can
142 use i_io_write() etc since they're available as macros in older
143 versions of Imager.
144
145 - eliminate the final remnants of io_glue_commit_types().
146
147 - bump IMAGER_API_VERSION, since the above may break assumptions.
148
149 - removed the long unused i_gen_reader() and i_gen_writer() utility
150 functions.

6ad7e4bc
TC
153===========
154
0c647c9a
TC
155The main changes in the release versus 0.84 are:
156
157 - on 64-bit systems, 64-bit types are consistently used for image
158 dimensions and co-ordinated, and for memory block sizes.
159
160 - handle IFD loops in TIFF files correctly. Previously this would
161 lead to an infinite loop.
162
6ad7e4bc
TC
163Bug fixes:
164
165 - fix the link in the getheight() entry in the method index

171favourable.
6b7197d0
TC
172
173Bug fixes:
174
175 - the image file limits set by set_file_limits() weren't being
176 checked when reading TIFF files.
177 https://rt.cpan.org/Ticket/Display.html?id=69915
178
5970bd39
TC
179 - Provide more information about file format module load errors on a
180 failed image file read() or write().
181 https://rt.cpan.org/Ticket/Display.html?id=69194
182
4ce3551c
TC
183 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
184 through TIFF images, since it checks for IFD loops.
185 https://rt.cpan.org/Ticket/Display.html?id=69914
186
a16bca6d
TC
187 - don't leak memory when out of range palette indexes are supplied to
188 setscanline().
189 https://rt.cpan.org/Ticket/Display.html?id=69242
190
191 - require a later version of CPAN::Meta to ensure JSON::PP and
192 CPAN::Meta::YAML are available.
193 https://rt.cpan.org/Ticket/Display.html?id=69008
194
ac575c5f
TC
195 - hoist the per-line calculations for the flines implementations, and
196 modernize the tests a bit.
197 https://rt.cpan.org/Ticket/Display.html?id=70126
198
86c8d19a
TC
199 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
200 them when available.

202
a3fd7df7
TC
203 - if t1lib failed to reinitialize it would be left as marked

210Imager 0.84_01 - 8 Aug 2011
211==============
212
213Development release as a sanity check for the types re-work.
8d14daab
TC
214
215Massive types re-work:
216
217 - the type used internally for pixel co-ordinates and image sizes is
218 now 64-bit on 64-bit platforms (at least sane ones).
219
220 - size_t is now used consistently for memory block sizes.
221
222 - since this changes the binary interface, the Imager API version has
223 been incremented. Any module that uses the API will need to be
224 rebuilt. In most cases that will be enough, but calls to any APIs
225 that take a pointer to image sizes may need source changes.
226
227 - you should be able to create very large images on 64-bit systems,
228 if you have enough memory. Successfully created a 32768 x 49192 x
229 3 channel image, filled with a tiled image and scaled it. The
230 unscaled image was also successfully saved to a JPEG.
231
232 - check the image size before attempting to write BMP, GIF, JPEG,
233 PNG, SGI, TGA, TIFF images.
234
235 - correctly handle reading TGA images over 32767 pixels wide or tall.
236
237Incidental changes:
238
239 - the gif_left and gif_top tags are now clamped to non-negative
240 values when writing a GIF image.
241
242 - removed dead callback read/write code
243
244The default maximum memory size when reading files is now 1G.

247===========
248
249 - Imager no longer inherits from Exporter (unless you're running an
250 old, old perl.
251
92e9df65

270
6d068d36
TC
271 - convert colors to grayscale if the supplied (or generated) palette
272 contains only grays when performing error diffusion color
273 translation.
274 https://rt.cpan.org/Ticket/Display.html?id=68508
275
59c150a4
TC
276 - writing a paletted image to GIF wouldn't always use the colors
277 supplied (or generated, eg. via make_colors => "mono"), which was
278 confusing at best.
279 https://rt.cpan.org/Ticket/Display.html?id=67912
280
5b480b14
TC
281 - replace (imager|tony)@imager.perl.org in the doc, since I don't

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

2368cfec
TC
316===========
317
318Bug fixes:
319
320 - eliminate calls to i_has_format() from the test suite, since it's
321 no longer a useful way to check for file format support. Eliminate
322 i_has_format() from the functions exposed via XS.
323 https://rt.cpan.org/Ticket/Display.html?id=65863
324
7540f84a
TC
325 - eliminate calls to note(), which isn't in the (very old) version of
326 Test::More we have as a pre-requisite. note() is modern enough
327 that I don't feel a need to require a Test::More upgrade for it.
328 https://rt.cpan.org/Ticket/Display.html?id=65864
329
81984f30

340 downgrade the version in this file.
341 https://rt.cpan.org/Ticket/Display.html?id=66250
342
343 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
344 that option for the directories that would normally go in
345 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

407 just a little darker.
408
9a5df694

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

421
2a2c791f
TC
422 - the convert() method now optimizes the case where all output
423 channels are either 0, sourced from a single input channel or 1.
424 This significantly speeds up presets like "addalpha", "green".

945 - some TGA images weren't being detected correctly as TGA images
946 https://rt.cpan.org/Ticket/Display.html?id=32925
947
948 - handling of the left-over bit for 16-bit/pixel TGA images has been
949 changed to match the behaviour of the GIMP. Previously the bit
950 being set was treated as an opaque pixel, but one user reported a
951 problem with loading such an image. I haven't been able to find any
952 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
953 I'll match it's behaviour. See issue 114913 in the GIMP's
954 bugzilla.

1275This is primarily a bug fix release.
1276
1277Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1278
1279There is one new feature:
1280
1281 - the Win32 font driver now supports UTF8 (RT 22166)
1282 http://www.cpanforum.com/threads/3276
1283 http://rt.cpan.org/Ticket/Display.html?id=22166
1284
1285Several bugs were fixed:
1286
1287 - the string() method would not output the string "0"
1288 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1289
1290 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1291 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1292
1293 - the gif_disposal and gif_user_input tags weren't being read from
1294 the file correctly
1295 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1296
1297 - gif.c was failing to build under MSVC
1298 http://rt.cpan.org/Ticket/Display.html?id=23922
1299
1300 - in some cases strings passed to the string() method were treated as
1301 terminated by NUL (chr 0)
1302 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1303
1304 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1305 that's the default build name for zlib on Win32.
1306 http://rt.cpan.org/Ticket/Display.html?id=23064
1307
1308 - search $Config{incpath} for headers too, which we should have been
1309 doing all along.
1310
1311Win32 font driver fixes:
1312
1313 - the global descent value from bounding box was the wrong sign
1314 http://www.cpanforum.com/threads/3276
1315
1316 - if the first or last glyph overflowed the left or right side of the
1317 advance width they would be clipped
1318
1319
1320Imager 0.54 - 14 Sep 2006
1321===========
1322
1323This is primarily a feature release:
1324
1325 - a new qtype value 'mixing' has been added to the scale()
1326 method. This is faster than 'normal', slower than 'preview'. This
1327 is based on the method used by pnmscale, and seems to produce less
1328 blurry results than normal.
1329 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1330
1331 - the rubthrough() method can now render onto images with an alpha
1332 channel.
1333 http://rt.cpan.org/Ticket/Display.html?id=20678
1334
1335 - the read_multi() method now falls back to calling doing a single
1336 image read via the read() method and write_multi() will now fall
1337 back to calling write() if a single image is supplied. This means
1338 you can simply call the read_multi() or write_multi() functions
1339 without having to check if the type is formatted by that method.

1343 - the GIF loop extension can now be written. If you don't have
1344 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1345 should upgrade.
1346 http://rt.cpan.org/Ticket/Display.html?id=21185
1347
1348 - getscanline() and setscanline() can now read/write palette index
1349 based data from/to the image for paletted images, by setting type to
1350 'index'.

1360===========
1361
1362This is a bugfix release.
1363
1364Some test code was left in a code path not covered by the test

1370Imager 0.52 - 25 Jul 2006
1371===========
1372
1373This is primarily a feature release, but contains a fair few bug
1374fixes, new features:
1375
1376 - ability to read and write MS Windows ICO and CUR files
1377
1378 - you can now add file format plugins to support new file formats
1379
1380 - add POD coverage tests
1381
1382 - setcolors() and addcolors() now accept color names and so on
1383 instead of requiring Imager::Color objects.
1384 http://rt.cpan.org/Ticket/Display.html?id=20056
1385
1386 - flood_fill() can now fill to a specified border color instead of
1387 just to the area the same color as the seed.
1388 http://rt.cpan.org/Ticket/Display.html?id=19618
1389
1390
1391Bug fixes:
1392
1393 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1394 calculating the advance width.
1395 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1396
1397 - bounding_box for the T1 driver wasn't including leading and
1398 trailing spaces in the bounding box as the other drivers did, it also
1399 produced strange results for empty strings or strings containing only
1400 spaces
1401
1402 - when reading CMYK jpeg images they were being transferred to the
1403 image object as is, producing a four channel image. It only looked ok
1404 due to an old still unfixed Photoshop bug. We now convert from the
1405 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1406 http://rt.cpan.org/Ticket/Display.html?id=20416
1407
1408 - reading a CYMK TIFF would result in a 4 channel image, reading any
1409 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1410 result in an error.
1411 http://rt.cpan.org/Ticket/Display.html?id=20415
1412
1413 - added /usr/local/include to the default include search path, since
1414 we were already searching /usr/local/lib for libraries.
1415
1416And various minor fixes and documentation updates.
