31
5efba0c6
TC
32 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
33 to synthesize it from overloaded "".
34
73e3ff55
TC
35 - use T1_StrError() for error messages on modern libt1
36 https://rt.cpan.org/Ticket/Display.html?id=69879
37
38 - actually load the font rather than just adding it to the catalog on
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

6d5c85a2 60==============
a7e32beb
TC
61
62 - add simple tests for the Imager::Test test_image generators
63
6d5c85a2
TC
64 - io_glue I/O buffering re-work:
65
66 - reorganize io_glue to do it's own buffering by default
67
68 - the unbuffered functions are available as i_io_raw_read() (or
69 raw_read() from perl) etc but are not recommended for typical
70 use.
71
72 - use the new i_io_peekn() when checking for file magic to avoid
73 seek, allowing Imager to detect the file type and read the file
74 from an unseekable stream (for formats that don't use random
75 access)
76
77 - added several new I/O layer API functions.
78
79 - fix the TGA performance problem, most noticably on Win32
80 https://rt.cpan.org/Ticket/Display.html?id=70037
81
82 - TIFF now uses wrapper functions of the correct types to avoid casts
83 https://rt.cpan.org/Ticket/Display.html?id=69912
84
85 - the callback IO object did its own buffering, controlled by the
86 maxbuffer parameter supplied to the read() and write() methods.
87 This buffering has been removed, to avoid redundancy with the
88 common io_glue buffering. This also avoids a bug in that code
89 which could rarely pass a zero length to the read callback and
90 then panic about the result.
91
92 - the callback IO object now tests the result of calling the close
93 callback, which should return true for success.
94
95 - the PNM reader did its own buffering. This buffering has been
96 removed to avoid redundancy with the common io_glue buffering.
97
98 - previously the read handlers for fd and callback I/O layers would
99 call the underlying interface (POSIX read or your supplied callback)
100 until it filled the buffer. It now only makes one call.
101
102 - added public constructors for I/O layer objects (see Imager::IO)
103
104 - all core file handlers now use the i_io_foo() wrappers to gain
105 access to buffered I/O rather than calling the I/O layer
106 callbacks directly.
107
108 - all core file handlers now check for error on close.
109
110 - Backward compatibility: if you hava custom file handlers, you can
111 use i_io_write() etc since they're available as macros in older
112 versions of Imager.
113
114 - eliminate the final remnants of io_glue_commit_types().
115
116 - bump IMAGER_API_VERSION, since the above may break assumptions.
117
118 - removed the long unused i_gen_reader() and i_gen_writer() utility
119 functions.

6ad7e4bc
TC
122===========
123
0c647c9a
TC
124The main changes in the release versus 0.84 are:
125
126 - on 64-bit systems, 64-bit types are consistently used for image
127 dimensions and co-ordinated, and for memory block sizes.
128
129 - handle IFD loops in TIFF files correctly. Previously this would
130 lead to an infinite loop.
131
6ad7e4bc
TC
132Bug fixes:
133
134 - fix the link in the getheight() entry in the method index

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

171
a3fd7df7
TC
172 - if t1lib failed to reinitialize it would be left as marked

179Imager 0.84_01 - 8 Aug 2011
180==============
181
182Development release as a sanity check for the types re-work.
8d14daab
TC
183
184Massive types re-work:
185
186 - the type used internally for pixel co-ordinates and image sizes is
187 now 64-bit on 64-bit platforms (at least sane ones).
188
189 - size_t is now used consistently for memory block sizes.
190
191 - since this changes the binary interface, the Imager API version has
192 been incremented. Any module that uses the API will need to be
193 rebuilt. In most cases that will be enough, but calls to any APIs
194 that take a pointer to image sizes may need source changes.
195
196 - you should be able to create very large images on 64-bit systems,
197 if you have enough memory. Successfully created a 32768 x 49192 x
198 3 channel image, filled with a tiled image and scaled it. The
199 unscaled image was also successfully saved to a JPEG.
200
201 - check the image size before attempting to write BMP, GIF, JPEG,
202 PNG, SGI, TGA, TIFF images.
203
204 - correctly handle reading TGA images over 32767 pixels wide or tall.
205
206Incidental changes:
207
208 - the gif_left and gif_top tags are now clamped to non-negative
209 values when writing a GIF image.
210
211 - removed dead callback read/write code
212
213The default maximum memory size when reading files is now 1G.

b1e66a82
TC
216===========
217
218 - Imager no longer inherits from Exporter (unless you're running an
219 old, old perl.
220
92e9df65
TC
221 - Imager can now write progressive JPEGs (it could always read them).
222 https://rt.cpan.org/Ticket/Display.html?id=68691
223
10ea52a3
TC
224Bug fixes:
225

239
6d068d36
TC
240 - convert colors to grayscale if the supplied (or generated) palette
241 contains only grays when performing error diffusion color
242 translation.
243 https://rt.cpan.org/Ticket/Display.html?id=68508
244
59c150a4
TC
245 - writing a paletted image to GIF wouldn't always use the colors
246 supplied (or generated, eg. via make_colors => "mono"), which was
247 confusing at best.
248 https://rt.cpan.org/Ticket/Display.html?id=67912
249
5b480b14
TC
250 - replace (imager|tony)@imager.perl.org in the doc, since I don't

deb1a916
TC
267
268Bug fixes:
269
270 - Imager::Font::T1 incorrectly checked for absolute filename under
271 Win32. Thanks to kmx for the report and fix.
272 https://rt.cpan.org/Ticket/Display.html?id=67963
273
618a3282
TC
274 - compose() with the target, source or mask position off the top or
275 left of the target image didn't clip the source image correctly.
276 https://rt.cpan.org/Ticket/Display.html?id=67220
277
278 - compose() now returns a useful error message on a non-positive
279 opacity.
280
281 - compose.im now at 100% test coverage. (As opposed to, umm, much,
282 much less.)
283
c1d16c8f 284Imager 0.82 - 14 Mar 2011
2368cfec
TC
285===========
286
287Bug fixes:
288
289 - eliminate calls to i_has_format() from the test suite, since it's
290 no longer a useful way to check for file format support. Eliminate
291 i_has_format() from the functions exposed via XS.
292 https://rt.cpan.org/Ticket/Display.html?id=65863
293
7540f84a
TC
294 - eliminate calls to note(), which isn't in the (very old) version of
295 Test::More we have as a pre-requisite. note() is modern enough
296 that I don't feel a need to require a Test::More upgrade for it.
297 https://rt.cpan.org/Ticket/Display.html?id=65864
298
81984f30
TC
299 - skip the threads tests on Test::More 2.00_*

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

392 channels are either 0, sourced from a single input channel or 1.
393 This significantly speeds up presets like "addalpha", "green".

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

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

933 - the old dynaload code used Mach API functions to load dynamic
934 libraries on Mac OS X. These APIs have been deprecated in OS X
935 10.5 and were causing some build problems.
936 So henceforth Imager uses the dlopen() family of functions, and you
937 will need version 10.3 or later of OS X.

1242===========

1244This is primarily a bug fix release.
1245
1246Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1247
1248There is one new feature:
1249
1250 - the Win32 font driver now supports UTF8 (RT 22166)
1251 http://www.cpanforum.com/threads/3276
1252 http://rt.cpan.org/Ticket/Display.html?id=22166
1253
1254Several bugs were fixed:
1255
1256 - the string() method would not output the string "0"
1257 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1258
1259 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1260 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1261
1262 - the gif_disposal and gif_user_input tags weren't being read from
1263 the file correctly
1264 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1265
1266 - gif.c was failing to build under MSVC
1267 http://rt.cpan.org/Ticket/Display.html?id=23922
1268
1269 - in some cases strings passed to the string() method were treated as
1270 terminated by NUL (chr 0)
1271 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1272
1273 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1274 that's the default build name for zlib on Win32.
1275 http://rt.cpan.org/Ticket/Display.html?id=23064
1276
1277 - search $Config{incpath} for headers too, which we should have been
1278 doing all along.
1279
1280Win32 font driver fixes:
1281
1282 - the global descent value from bounding box was the wrong sign
1283 http://www.cpanforum.com/threads/3276
1284
1285 - if the first or last glyph overflowed the left or right side of the
1286 advance width they would be clipped

1288
1289Imager 0.54 - 14 Sep 2006
1290===========
1291
1292This is primarily a feature release:
1293
1294 - a new qtype value 'mixing' has been added to the scale()
1295 method. This is faster than 'normal', slower than 'preview'. This
1296 is based on the method used by pnmscale, and seems to produce less
1297 blurry results than normal.
1298 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1299
1300 - the rubthrough() method can now render onto images with an alpha
1301 channel.
1302 http://rt.cpan.org/Ticket/Display.html?id=20678
1303
1304 - the read_multi() method now falls back to calling doing a single
1305 image read via the read() method and write_multi() will now fall
1306 back to calling write() if a single image is supplied. This means
1307 you can simply call the read_multi() or write_multi() functions
1308 without having to check if the type is formatted by that method.
1309 http://rt.cpan.org/Ticket/Display.html?id=19457
1310 http://rt.cpan.org/Ticket/Display.html?id=19458
1311
1312 - the GIF loop extension can now be written. If you don't have
1313 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1314 should upgrade.
1315 http://rt.cpan.org/Ticket/Display.html?id=21185
1316
1317 - getscanline() and setscanline() can now read/write palette index
1318 based data from/to the image for paletted images, by setting type to
1319 'index'.
1320 http://rt.cpan.org/Ticket/Display.html?id=20338
1321
1322 - we no longer hassle you to disable GIF support
1323 http://rt.cpan.org/Ticket/Display.html?id=20687
1324
1325 - minor documentation fixes
1326
1327
1328Imager 0.53 - 26 Jul 2006
1329===========
1330
1331This is a bugfix release.
1332
1333Some test code was left in a code path not covered by the test
1334suite. A test was added to cover this code path and the test code was
1335removed.

1343fixes, new features:
1344
1345 - ability to read and write MS Windows ICO and CUR files
1346
1347 - you can now add file format plugins to support new file formats
1348
1349 - add POD coverage tests
1350
1351 - setcolors() and addcolors() now accept color names and so on
1352 instead of requiring Imager::Color objects.

1354

1360Bug fixes:
1361
1362 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1363 calculating the advance width.
1364 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1365
1366 - bounding_box for the T1 driver wasn't including leading and
1367 trailing spaces in the bounding box as the other drivers did, it also
1368 produced strange results for empty strings or strings containing only
1369 spaces
1370
1371 - when reading CMYK jpeg images they were being transferred to the
1372 image object as is, producing a four channel image. It only looked ok
1373 due to an old still unfixed Photoshop bug. We now convert from the
1374 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1375 http://rt.cpan.org/Ticket/Display.html?id=20416
1376
1377 - reading a CYMK TIFF would result in a 4 channel image, reading any
1378 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1379 result in an error.

1381
1382 - added /usr/local/include to the default include search path, since
1383 we were already searching /usr/local/lib for libraries.
1384
1385And various minor fixes and documentation updates.
