31
5efba0c6

73e3ff55
TC
35 - use T1_StrError() for error messages on modern libt1
36 https://rt.cpan.org/Ticket/Display.html?id=69879

39 creation.
40
41 - Imager::Font->new now produces better error messages for the T1
42 engine.
43
6e938c74
TC
44 - the font has_chars() method now returns perl's true and false

31be6e9a 56Imager 0.85_01 - 10 Oct 2011
6d5c85a2 57==============
a7e32beb
TC
58
59 - add simple tests for the Imager::Test test_image generators
60
6d5c85a2
TC
61 - io_glue I/O buffering re-work:
62
63 - reorganize io_glue to do it's own buffering by default
64
65 - the unbuffered functions are available as i_io_raw_read() (or
66 raw_read() from perl) etc but are not recommended for typical
67 use.
68
69 - use the new i_io_peekn() when checking for file magic to avoid
70 seek, allowing Imager to detect the file type and read the file
71 from an unseekable stream (for formats that don't use random
72 access)
73
74 - added several new I/O layer API functions.
75
76 - fix the TGA performance problem, most noticably on Win32
77 https://rt.cpan.org/Ticket/Display.html?id=70037
78
79 - TIFF now uses wrapper functions of the correct types to avoid casts
80 https://rt.cpan.org/Ticket/Display.html?id=69912
81
82 - the callback IO object did its own buffering, controlled by the
83 maxbuffer parameter supplied to the read() and write() methods.
84 This buffering has been removed, to avoid redundancy with the
85 common io_glue buffering. This also avoids a bug in that code
86 which could rarely pass a zero length to the read callback and
87 then panic about the result.
88
89 - the callback IO object now tests the result of calling the close
90 callback, which should return true for success.
91
92 - the PNM reader did its own buffering. This buffering has been
93 removed to avoid redundancy with the common io_glue buffering.
94
95 - previously the read handlers for fd and callback I/O layers would
96 call the underlying interface (POSIX read or your supplied callback)
97 until it filled the buffer. It now only makes one call.
98
99 - added public constructors for I/O layer objects (see Imager::IO)
100
101 - all core file handlers now use the i_io_foo() wrappers to gain
102 access to buffered I/O rather than calling the I/O layer
103 callbacks directly.
104
105 - all core file handlers now check for error on close.
106
107 - Backward compatibility: if you hava custom file handlers, you can
108 use i_io_write() etc since they're available as macros in older
109 versions of Imager.
110
111 - eliminate the final remnants of io_glue_commit_types().
112
113 - bump IMAGER_API_VERSION, since the above may break assumptions.
114
115 - removed the long unused i_gen_reader() and i_gen_writer() utility
116 functions.

6ad7e4bc
TC
119===========
120
0c647c9a
TC
121The main changes in the release versus 0.84 are:
122
123 - on 64-bit systems, 64-bit types are consistently used for image
124 dimensions and co-ordinated, and for memory block sizes.
125
126 - handle IFD loops in TIFF files correctly. Previously this would
127 lead to an infinite loop.
128
6ad7e4bc
TC
129Bug fixes:
130
131 - fix the link in the getheight() entry in the method index

137favourable.
6b7197d0
TC
138
139Bug fixes:
140
141 - the image file limits set by set_file_limits() weren't being
142 checked when reading TIFF files.
143 https://rt.cpan.org/Ticket/Display.html?id=69915
144
5970bd39
TC
145 - Provide more information about file format module load errors on a
146 failed image file read() or write().
147 https://rt.cpan.org/Ticket/Display.html?id=69194
148
4ce3551c
TC
149 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
150 through TIFF images, since it checks for IFD loops.
151 https://rt.cpan.org/Ticket/Display.html?id=69914
152
a16bca6d
TC
153 - don't leak memory when out of range palette indexes are supplied to
154 setscanline().
155 https://rt.cpan.org/Ticket/Display.html?id=69242
156
157 - require a later version of CPAN::Meta to ensure JSON::PP and
158 CPAN::Meta::YAML are available.
159 https://rt.cpan.org/Ticket/Display.html?id=69008
160
ac575c5f
TC
161 - hoist the per-line calculations for the flines implementations, and
162 modernize the tests a bit.
163 https://rt.cpan.org/Ticket/Display.html?id=70126
164
86c8d19a
TC
165 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
166 them when available.
167 https://rt.cpan.org/Ticket/Display.html?id=69147
168
a3fd7df7
TC
169 - if t1lib failed to reinitialize it would be left as marked

176Imager 0.84_01 - 8 Aug 2011
177==============
178
179Development release as a sanity check for the types re-work.
8d14daab
TC
180
181Massive types re-work:
182
183 - the type used internally for pixel co-ordinates and image sizes is
184 now 64-bit on 64-bit platforms (at least sane ones).
185
186 - size_t is now used consistently for memory block sizes.
187
188 - since this changes the binary interface, the Imager API version has
189 been incremented. Any module that uses the API will need to be
190 rebuilt. In most cases that will be enough, but calls to any APIs
191 that take a pointer to image sizes may need source changes.
192
193 - you should be able to create very large images on 64-bit systems,
194 if you have enough memory. Successfully created a 32768 x 49192 x
195 3 channel image, filled with a tiled image and scaled it. The
196 unscaled image was also successfully saved to a JPEG.
197
198 - check the image size before attempting to write BMP, GIF, JPEG,
199 PNG, SGI, TGA, TIFF images.
200
201 - correctly handle reading TGA images over 32767 pixels wide or tall.
202
203Incidental changes:
204
205 - the gif_left and gif_top tags are now clamped to non-negative
206 values when writing a GIF image.
207
208 - removed dead callback read/write code
209
210The default maximum memory size when reading files is now 1G.

bd80e51e 212Imager 0.84 - 20 Jun 2011
b1e66a82
TC
213===========
214
215 - Imager no longer inherits from Exporter (unless you're running an
216 old, old perl.
217
92e9df65
TC
218 - Imager can now write progressive JPEGs (it could always read them).
219 https://rt.cpan.org/Ticket/Display.html?id=68691
220
10ea52a3
TC
221Bug fixes:
222
223 - re-work, document and test Imager's logging facility.

236
6d068d36
TC
237 - convert colors to grayscale if the supplied (or generated) palette
238 contains only grays when performing error diffusion color
239 translation.
240 https://rt.cpan.org/Ticket/Display.html?id=68508
241
59c150a4
TC
242 - writing a paletted image to GIF wouldn't always use the colors
243 supplied (or generated, eg. via make_colors => "mono"), which was
244 confusing at best.
245 https://rt.cpan.org/Ticket/Display.html?id=67912
246
5b480b14
TC
247 - replace (imager|tony)@imager.perl.org in the doc, since I don't

263Dev release, in case the compose tests are too sensitive.
deb1a916
TC
264
265Bug fixes:
266
267 - Imager::Font::T1 incorrectly checked for absolute filename under
268 Win32. Thanks to kmx for the report and fix.
269 https://rt.cpan.org/Ticket/Display.html?id=67963
270
618a3282
TC
271 - compose() with the target, source or mask position off the top or
272 left of the target image didn't clip the source image correctly.
273 https://rt.cpan.org/Ticket/Display.html?id=67220
274
275 - compose() now returns a useful error message on a non-positive
276 opacity.
277
278 - compose.im now at 100% test coverage. (As opposed to, umm, much,
279 much less.)
280
c1d16c8f 281Imager 0.82 - 14 Mar 2011
2368cfec
TC
282===========
283
284Bug fixes:
285
286 - eliminate calls to i_has_format() from the test suite, since it's
287 no longer a useful way to check for file format support. Eliminate
288 i_has_format() from the functions exposed via XS.
289 https://rt.cpan.org/Ticket/Display.html?id=65863
290
7540f84a
TC
291 - eliminate calls to note(), which isn't in the (very old) version of
292 Test::More we have as a pre-requisite. note() is modern enough
293 that I don't feel a need to require a Test::More upgrade for it.
294 https://rt.cpan.org/Ticket/Display.html?id=65864
295
81984f30
TC
296 - skip the threads tests on Test::More 2.00_*

305 - increase the version of Imager::Font::Type1 so that upgrades don't
306 downgrade the version in this file.
307 https://rt.cpan.org/Ticket/Display.html?id=66250
308
309 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
310 that option for the directories that would normally go in
311 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

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

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

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

915 changed to match the behaviour of the GIMP. Previously the bit
916 being set was treated as an opaque pixel, but one user reported a
917 problem with loading such an image. I haven't been able to find any
918 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
919 I'll match it's behaviour. See issue 114913 in the GIMP's
920 bugzilla.

930 - the old dynaload code used Mach API functions to load dynamic
931 libraries on Mac OS X. These APIs have been deprecated in OS X
932 10.5 and were causing some build problems.
933 So henceforth Imager uses the dlopen() family of functions, and you
934 will need version 10.3 or later of OS X.

1241This is primarily a bug fix release.
1242
1243Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1244
1245There is one new feature:

1249 http://rt.cpan.org/Ticket/Display.html?id=22166

1252
1253 - the string() method would not output the string "0"
1254 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1255
1256 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1257 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1258
1259 - the gif_disposal and gif_user_input tags weren't being read from
1260 the file correctly
1261 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1262
1263 - gif.c was failing to build under MSVC
1264 http://rt.cpan.org/Ticket/Display.html?id=23922
1265
1266 - in some cases strings passed to the string() method were treated as
1267 terminated by NUL (chr 0)
1268 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1269
1270 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1271 that's the default build name for zlib on Win32.
1272 http://rt.cpan.org/Ticket/Display.html?id=23064
1273
1274 - search $Config{incpath} for headers too, which we should have been
1275 doing all along.
1276
1277Win32 font driver fixes:
1278
1279 - the global descent value from bounding box was the wrong sign
1280 http://www.cpanforum.com/threads/3276
1281
1282 - if the first or last glyph overflowed the left or right side of the

1285
1286Imager 0.54 - 14 Sep 2006
1287===========
1288
1289This is primarily a feature release:
1290
1291 - a new qtype value 'mixing' has been added to the scale()
1292 method. This is faster than 'normal', slower than 'preview'. This
1293 is based on the method used by pnmscale, and seems to produce less
1294 blurry results than normal.
1295 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1296
1297 - the rubthrough() method can now render onto images with an alpha
1298 channel.
1299 http://rt.cpan.org/Ticket/Display.html?id=20678
1300
1301 - the read_multi() method now falls back to calling doing a single
1302 image read via the read() method and write_multi() will now fall
1303 back to calling write() if a single image is supplied. This means
1304 you can simply call the read_multi() or write_multi() functions
1305 without having to check if the type is formatted by that method.
1306 http://rt.cpan.org/Ticket/Display.html?id=19457
1307 http://rt.cpan.org/Ticket/Display.html?id=19458
1308
1309 - the GIF loop extension can now be written. If you don't have
1310 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1311 should upgrade.
1312 http://rt.cpan.org/Ticket/Display.html?id=21185
1313
1314 - getscanline() and setscanline() can now read/write palette index
1315 based data from/to the image for paletted images, by setting type to
1316 'index'.
1317 http://rt.cpan.org/Ticket/Display.html?id=20338
1318
1319 - we no longer hassle you to disable GIF support
1320 http://rt.cpan.org/Ticket/Display.html?id=20687
1321
1322 - minor documentation fixes
1323

1325Imager 0.53 - 26 Jul 2006
1326===========
1327
1328This is a bugfix release.

1344 - you can now add file format plugins to support new file formats
1345
1346 - add POD coverage tests
1347

1349 instead of requiring Imager::Color objects.

1357Bug fixes:
1358
1359 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1360 calculating the advance width.
1361 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1362
1363 - bounding_box for the T1 driver wasn't including leading and
1364 trailing spaces in the bounding box as the other drivers did, it also
1365 produced strange results for empty strings or strings containing only
1366 spaces
1367
1368 - when reading CMYK jpeg images they were being transferred to the
1369 image object as is, producing a four channel image. It only looked ok
1370 due to an old still unfixed Photoshop bug. We now convert from the
1371 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1372 http://rt.cpan.org/Ticket/Display.html?id=20416
1373
1374 - reading a CYMK TIFF would result in a 4 channel image, reading any
1375 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1376 result in an error.

1378
1379 - added /usr/local/include to the default include search path, since
1380 we were already searching /usr/local/lib for libraries.
1381
1382And various minor fixes and documentation updates.
