28
954ac5d1

29 - depend on Scalar::Util, since we use it and older perls don't have
30 it.
31
5efba0c6
TC
32 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
33 to synthesize it from overloaded "".
34
73e3ff55

31be6e9a 44Imager 0.85_01 - 10 Oct 2011
6d5c85a2 45==============
a7e32beb
TC
46
47 - add simple tests for the Imager::Test test_image generators
48
6d5c85a2
TC
49 - io_glue I/O buffering re-work:
50
51 - reorganize io_glue to do it's own buffering by default
52
53 - the unbuffered functions are available as i_io_raw_read() (or
54 raw_read() from perl) etc but are not recommended for typical
55 use.
56
57 - use the new i_io_peekn() when checking for file magic to avoid
58 seek, allowing Imager to detect the file type and read the file
59 from an unseekable stream (for formats that don't use random
60 access)
61
62 - added several new I/O layer API functions.
63
64 - fix the TGA performance problem, most noticably on Win32
65 https://rt.cpan.org/Ticket/Display.html?id=70037
66
67 - TIFF now uses wrapper functions of the correct types to avoid casts
68 https://rt.cpan.org/Ticket/Display.html?id=69912
69
70 - the callback IO object did its own buffering, controlled by the
71 maxbuffer parameter supplied to the read() and write() methods.
72 This buffering has been removed, to avoid redundancy with the
73 common io_glue buffering. This also avoids a bug in that code
74 which could rarely pass a zero length to the read callback and
75 then panic about the result.
76
77 - the callback IO object now tests the result of calling the close
78 callback, which should return true for success.
79
80 - the PNM reader did its own buffering. This buffering has been
81 removed to avoid redundancy with the common io_glue buffering.
82
83 - previously the read handlers for fd and callback I/O layers would
84 call the underlying interface (POSIX read or your supplied callback)
85 until it filled the buffer. It now only makes one call.
86
87 - added public constructors for I/O layer objects (see Imager::IO)
88
89 - all core file handlers now use the i_io_foo() wrappers to gain
90 access to buffered I/O rather than calling the I/O layer
91 callbacks directly.
92
93 - all core file handlers now check for error on close.
94
95 - Backward compatibility: if you hava custom file handlers, you can
96 use i_io_write() etc since they're available as macros in older
97 versions of Imager.
98
99 - eliminate the final remnants of io_glue_commit_types().
100
101 - bump IMAGER_API_VERSION, since the above may break assumptions.
102
103 - removed the long unused i_gen_reader() and i_gen_writer() utility
104 functions.

6ad7e4bc
TC
107===========
108
0c647c9a
TC
109The main changes in the release versus 0.84 are:
110
111 - on 64-bit systems, 64-bit types are consistently used for image
112 dimensions and co-ordinated, and for memory block sizes.
113
114 - handle IFD loops in TIFF files correctly. Previously this would
115 lead to an infinite loop.
116
6ad7e4bc
TC
117Bug fixes:
118
119 - fix the link in the getheight() entry in the method index

121Imager 0.84_02 - 22 Aug 2011
122==============
123
124Development release, this will become 0.85 if CPAN testers is
125favourable.
6b7197d0
TC
126
127Bug fixes:
128
129 - the image file limits set by set_file_limits() weren't being
130 checked when reading TIFF files.
131 https://rt.cpan.org/Ticket/Display.html?id=69915
132
5970bd39
TC
133 - Provide more information about file format module load errors on a
134 failed image file read() or write().
135 https://rt.cpan.org/Ticket/Display.html?id=69194
136
4ce3551c
TC
137 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
138 through TIFF images, since it checks for IFD loops.
139 https://rt.cpan.org/Ticket/Display.html?id=69914
140
a16bca6d
TC
141 - don't leak memory when out of range palette indexes are supplied to
142 setscanline().
143 https://rt.cpan.org/Ticket/Display.html?id=69242
144
145 - require a later version of CPAN::Meta to ensure JSON::PP and
146 CPAN::Meta::YAML are available.
147 https://rt.cpan.org/Ticket/Display.html?id=69008
148
ac575c5f
TC
149 - hoist the per-line calculations for the flines implementations, and
150 modernize the tests a bit.
151 https://rt.cpan.org/Ticket/Display.html?id=70126
152
86c8d19a
TC
153 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
154 them when available.
155 https://rt.cpan.org/Ticket/Display.html?id=69147
156
a3fd7df7
TC
157 - if t1lib failed to reinitialize it would be left as marked
158 initialized.

164Imager 0.84_01 - 8 Aug 2011
165==============
166
167Development release as a sanity check for the types re-work.
8d14daab
TC
168
169Massive types re-work:
170
171 - the type used internally for pixel co-ordinates and image sizes is
172 now 64-bit on 64-bit platforms (at least sane ones).
173
174 - size_t is now used consistently for memory block sizes.
175
176 - since this changes the binary interface, the Imager API version has
177 been incremented. Any module that uses the API will need to be
178 rebuilt. In most cases that will be enough, but calls to any APIs
179 that take a pointer to image sizes may need source changes.
180
181 - you should be able to create very large images on 64-bit systems,
182 if you have enough memory. Successfully created a 32768 x 49192 x
183 3 channel image, filled with a tiled image and scaled it. The
184 unscaled image was also successfully saved to a JPEG.
185
186 - check the image size before attempting to write BMP, GIF, JPEG,
187 PNG, SGI, TGA, TIFF images.
188
189 - correctly handle reading TGA images over 32767 pixels wide or tall.
190
191Incidental changes:
192
193 - the gif_left and gif_top tags are now clamped to non-negative
194 values when writing a GIF image.
195
196 - removed dead callback read/write code
197
198The default maximum memory size when reading files is now 1G.

b1e66a82
TC
201===========
202
203 - Imager no longer inherits from Exporter (unless you're running an
204 old, old perl.
205
92e9df65
TC
206 - Imager can now write progressive JPEGs (it could always read them).
207 https://rt.cpan.org/Ticket/Display.html?id=68691
208
10ea52a3
TC
209Bug fixes:
210
211 - re-work, document and test Imager's logging facility.

224
6d068d36
TC
225 - convert colors to grayscale if the supplied (or generated) palette
226 contains only grays when performing error diffusion color
227 translation.
228 https://rt.cpan.org/Ticket/Display.html?id=68508
229
59c150a4
TC
230 - writing a paletted image to GIF wouldn't always use the colors
231 supplied (or generated, eg. via make_colors => "mono"), which was
232 confusing at best.
233 https://rt.cpan.org/Ticket/Display.html?id=67912
234
5b480b14
TC
235 - replace (imager|tony)@imager.perl.org in the doc, since I don't
236 plan to continue receiving mail at that address.

251Dev release, in case the compose tests are too sensitive.
deb1a916
TC
252
253Bug fixes:
254
255 - Imager::Font::T1 incorrectly checked for absolute filename under
256 Win32. Thanks to kmx for the report and fix.
257 https://rt.cpan.org/Ticket/Display.html?id=67963
258
618a3282
TC
259 - compose() with the target, source or mask position off the top or
260 left of the target image didn't clip the source image correctly.
261 https://rt.cpan.org/Ticket/Display.html?id=67220
262
263 - compose() now returns a useful error message on a non-positive
264 opacity.
265
266 - compose.im now at 100% test coverage. (As opposed to, umm, much,
267 much less.)
268
c1d16c8f 269Imager 0.82 - 14 Mar 2011
2368cfec
TC
270===========
271
272Bug fixes:
273
274 - eliminate calls to i_has_format() from the test suite, since it's
275 no longer a useful way to check for file format support. Eliminate
276 i_has_format() from the functions exposed via XS.
277 https://rt.cpan.org/Ticket/Display.html?id=65863
278
7540f84a
TC
279 - eliminate calls to note(), which isn't in the (very old) version of
280 Test::More we have as a pre-requisite. note() is modern enough
281 that I don't feel a need to require a Test::More upgrade for it.
282 https://rt.cpan.org/Ticket/Display.html?id=65864
283
81984f30
TC
284 - skip the threads tests on Test::More 2.00_*

293 - increase the version of Imager::Font::Type1 so that upgrades don't
294 downgrade the version in this file.
295 https://rt.cpan.org/Ticket/Display.html?id=66250
296
297 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
298 that option for the directories that would normally go in
299 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

361 just a little darker.
362
9a5df694

363 - make the default color map build algorithm "mediancut". This
364 changes the default color map builder for writing GIFs back to what
365 it was in 0.77, reverting a performance regression.

375
2a2c791f
TC
376 - the convert() method now optimizes the case where all output
377 channels are either 0, sourced from a single input channel or 1.
378 This significantly speeds up presets like "addalpha", "green".
379 https://rt.cpan.org/Ticket/Display.html?id=51254

850
851 - rubthrough() now falls back to pasting when the source doesn't have
852 an alpha channel. This effectively treats the source as having a
853 max alpha channel, the right thing to do.

918 - the old dynaload code used Mach API functions to load dynamic
919 libraries on Mac OS X. These APIs have been deprecated in OS X
920 10.5 and were causing some build problems.
921 So henceforth Imager uses the dlopen() family of functions, and you
922 will need version 10.3 or later of OS X.

1226Imager 0.55 - 16 Dec 2006
1227===========
1228
1229This is primarily a bug fix release.
1230
1231Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1232
1233There is one new feature:
1234
1235 - the Win32 font driver now supports UTF8 (RT 22166)
1236 http://www.cpanforum.com/threads/3276
1237 http://rt.cpan.org/Ticket/Display.html?id=22166
1238
1239Several bugs were fixed:
1240
1241 - the string() method would not output the string "0"
1242 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1243
1244 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1245 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1246
1247 - the gif_disposal and gif_user_input tags weren't being read from
1248 the file correctly
1249 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1250
1251 - gif.c was failing to build under MSVC
1252 http://rt.cpan.org/Ticket/Display.html?id=23922
1253
1254 - in some cases strings passed to the string() method were treated as
1255 terminated by NUL (chr 0)
1256 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1257
1258 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1259 that's the default build name for zlib on Win32.
1260 http://rt.cpan.org/Ticket/Display.html?id=23064
1261
1262 - search $Config{incpath} for headers too, which we should have been
1263 doing all along.
1264
1265Win32 font driver fixes:
1266
1267 - the global descent value from bounding box was the wrong sign
1268 http://www.cpanforum.com/threads/3276
1269
1270 - if the first or last glyph overflowed the left or right side of the
1271 advance width they would be clipped
1272
1273
1274Imager 0.54 - 14 Sep 2006
1275===========
1276
1277This is primarily a feature release:
1278
1279 - a new qtype value 'mixing' has been added to the scale()
1280 method. This is faster than 'normal', slower than 'preview'. This
1281 is based on the method used by pnmscale, and seems to produce less
1282 blurry results than normal.
1283 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1284
1285 - the rubthrough() method can now render onto images with an alpha
1286 channel.
1287 http://rt.cpan.org/Ticket/Display.html?id=20678
1288
1289 - the read_multi() method now falls back to calling doing a single
1290 image read via the read() method and write_multi() will now fall
1291 back to calling write() if a single image is supplied. This means
1292 you can simply call the read_multi() or write_multi() functions
1293 without having to check if the type is formatted by that method.
1294 http://rt.cpan.org/Ticket/Display.html?id=19457
1295 http://rt.cpan.org/Ticket/Display.html?id=19458
1296
1297 - the GIF loop extension can now be written. If you don't have
1298 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1299 should upgrade.
1300 http://rt.cpan.org/Ticket/Display.html?id=21185
1301
1302 - getscanline() and setscanline() can now read/write palette index
1303 based data from/to the image for paletted images, by setting type to
1304 'index'.
1305 http://rt.cpan.org/Ticket/Display.html?id=20338
1306
1307 - we no longer hassle you to disable GIF support
1308 http://rt.cpan.org/Ticket/Display.html?id=20687
1309
1310 - minor documentation fixes
1311
1312
1313Imager 0.53 - 26 Jul 2006
1314===========
1315
1316This is a bugfix release.
1317
1318Some test code was left in a code path not covered by the test
1319suite. A test was added to cover this code path and the test code was
1320removed.

1330 - ability to read and write MS Windows ICO and CUR files
1331
1332 - you can now add file format plugins to support new file formats
1333
1334 - add POD coverage tests
1335
1336 - setcolors() and addcolors() now accept color names and so on
1337 instead of requiring Imager::Color objects.
1338 http://rt.cpan.org/Ticket/Display.html?id=20056
1339
1340 - flood_fill() can now fill to a specified border color instead of
1341 just to the area the same color as the seed.
1342 http://rt.cpan.org/Ticket/Display.html?id=19618
1343
1344
1345Bug fixes:
1346
1347 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1348 calculating the advance width.
1349 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1350
1351 - bounding_box for the T1 driver wasn't including leading and
1352 trailing spaces in the bounding box as the other drivers did, it also
1353 produced strange results for empty strings or strings containing only
