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
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
45 values in list context rather than integers, which should be more
46 efficient.

62
336ce474
TC
63 - we rely on Config.pm's d_vsnprintf as to whether we use
64 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
65 though it only has _ prefixed versions of these. Define our own
66 prefixed names on Win32.

31be6e9a 71Imager 0.85_01 - 10 Oct 2011
6d5c85a2 72==============
a7e32beb
TC
73
74 - add simple tests for the Imager::Test test_image generators
75
6d5c85a2
TC
76 - io_glue I/O buffering re-work:
77
78 - reorganize io_glue to do it's own buffering by default
79
80 - the unbuffered functions are available as i_io_raw_read() (or
81 raw_read() from perl) etc but are not recommended for typical
82 use.
83
84 - use the new i_io_peekn() when checking for file magic to avoid
85 seek, allowing Imager to detect the file type and read the file
86 from an unseekable stream (for formats that don't use random
87 access)
88
89 - added several new I/O layer API functions.
90
91 - fix the TGA performance problem, most noticably on Win32
92 https://rt.cpan.org/Ticket/Display.html?id=70037
93
94 - TIFF now uses wrapper functions of the correct types to avoid casts
95 https://rt.cpan.org/Ticket/Display.html?id=69912
96
97 - the callback IO object did its own buffering, controlled by the
98 maxbuffer parameter supplied to the read() and write() methods.
99 This buffering has been removed, to avoid redundancy with the
100 common io_glue buffering. This also avoids a bug in that code
101 which could rarely pass a zero length to the read callback and
102 then panic about the result.
103
104 - the callback IO object now tests the result of calling the close
105 callback, which should return true for success.
106
107 - the PNM reader did its own buffering. This buffering has been
108 removed to avoid redundancy with the common io_glue buffering.
109
110 - previously the read handlers for fd and callback I/O layers would
111 call the underlying interface (POSIX read or your supplied callback)
112 until it filled the buffer. It now only makes one call.
113
114 - added public constructors for I/O layer objects (see Imager::IO)
115
116 - all core file handlers now use the i_io_foo() wrappers to gain
117 access to buffered I/O rather than calling the I/O layer
118 callbacks directly.
119
120 - all core file handlers now check for error on close.
121
122 - Backward compatibility: if you hava custom file handlers, you can
123 use i_io_write() etc since they're available as macros in older
124 versions of Imager.
125
126 - eliminate the final remnants of io_glue_commit_types().
127
128 - bump IMAGER_API_VERSION, since the above may break assumptions.
129
130 - removed the long unused i_gen_reader() and i_gen_writer() utility
131 functions.

6ad7e4bc
TC
134===========
135
0c647c9a
TC
136The main changes in the release versus 0.84 are:
137
138 - on 64-bit systems, 64-bit types are consistently used for image
139 dimensions and co-ordinated, and for memory block sizes.
140
141 - handle IFD loops in TIFF files correctly. Previously this would
142 lead to an infinite loop.
143
6ad7e4bc
TC
144Bug fixes:
145
146 - fix the link in the getheight() entry in the method index

150
151Development release, this will become 0.85 if CPAN testers is
152favourable.
6b7197d0
TC
153
154Bug fixes:
155
156 - the image file limits set by set_file_limits() weren't being
157 checked when reading TIFF files.
158 https://rt.cpan.org/Ticket/Display.html?id=69915
159
5970bd39
TC
160 - Provide more information about file format module load errors on a
161 failed image file read() or write().
162 https://rt.cpan.org/Ticket/Display.html?id=69194
163
4ce3551c
TC
164 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
165 through TIFF images, since it checks for IFD loops.
166 https://rt.cpan.org/Ticket/Display.html?id=69914
167
a16bca6d
TC
168 - don't leak memory when out of range palette indexes are supplied to
169 setscanline().
170 https://rt.cpan.org/Ticket/Display.html?id=69242
171
172 - require a later version of CPAN::Meta to ensure JSON::PP and
173 CPAN::Meta::YAML are available.
174 https://rt.cpan.org/Ticket/Display.html?id=69008
175
ac575c5f
TC
176 - hoist the per-line calculations for the flines implementations, and
177 modernize the tests a bit.
178 https://rt.cpan.org/Ticket/Display.html?id=70126
179
86c8d19a
TC
180 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
181 them when available.
182 https://rt.cpan.org/Ticket/Display.html?id=69147
183
a3fd7df7
TC
184 - if t1lib failed to reinitialize it would be left as marked
185 initialized.

191Imager 0.84_01 - 8 Aug 2011
192==============
193
194Development release as a sanity check for the types re-work.
8d14daab
TC
195
196Massive types re-work:
197
198 - the type used internally for pixel co-ordinates and image sizes is
199 now 64-bit on 64-bit platforms (at least sane ones).
200
201 - size_t is now used consistently for memory block sizes.
202
203 - since this changes the binary interface, the Imager API version has
204 been incremented. Any module that uses the API will need to be
205 rebuilt. In most cases that will be enough, but calls to any APIs
206 that take a pointer to image sizes may need source changes.
207
208 - you should be able to create very large images on 64-bit systems,
209 if you have enough memory. Successfully created a 32768 x 49192 x
210 3 channel image, filled with a tiled image and scaled it. The
211 unscaled image was also successfully saved to a JPEG.
212
213 - check the image size before attempting to write BMP, GIF, JPEG,
214 PNG, SGI, TGA, TIFF images.
215
216 - correctly handle reading TGA images over 32767 pixels wide or tall.
217
218Incidental changes:
219
220 - the gif_left and gif_top tags are now clamped to non-negative
221 values when writing a GIF image.
222
223 - removed dead callback read/write code
224
225The default maximum memory size when reading files is now 1G.

b1e66a82
TC
228===========
229
230 - Imager no longer inherits from Exporter (unless you're running an
231 old, old perl.
232
92e9df65
TC
233 - Imager can now write progressive JPEGs (it could always read them).

235
10ea52a3
TC
236Bug fixes:
237

251
6d068d36
TC
252 - convert colors to grayscale if the supplied (or generated) palette
253 contains only grays when performing error diffusion color
254 translation.
255 https://rt.cpan.org/Ticket/Display.html?id=68508
256
59c150a4
TC
257 - writing a paletted image to GIF wouldn't always use the colors
258 supplied (or generated, eg. via make_colors => "mono"), which was
259 confusing at best.
260 https://rt.cpan.org/Ticket/Display.html?id=67912
261
5b480b14
TC
262 - replace (imager|tony)@imager.perl.org in the doc, since I don't

TC
279
280Bug fixes:
281

283 Win32. Thanks to kmx for the report and fix.
284 https://rt.cpan.org/Ticket/Display.html?id=67963
285
618a3282
TC
286 - compose() with the target, source or mask position off the top or
287 left of the target image didn't clip the source image correctly.
288 https://rt.cpan.org/Ticket/Display.html?id=67220
289
290 - compose() now returns a useful error message on a non-positive
291 opacity.
292
293 - compose.im now at 100% test coverage. (As opposed to, umm, much,
294 much less.)

c1d16c8f 296Imager 0.82 - 14 Mar 2011
2368cfec
TC
297===========
298
299Bug fixes:
300
301 - eliminate calls to i_has_format() from the test suite, since it's
302 no longer a useful way to check for file format support. Eliminate
303 i_has_format() from the functions exposed via XS.
304 https://rt.cpan.org/Ticket/Display.html?id=65863
305
7540f84a
TC
306 - eliminate calls to note(), which isn't in the (very old) version of
307 Test::More we have as a pre-requisite. note() is modern enough
308 that I don't feel a need to require a Test::More upgrade for it.
309 https://rt.cpan.org/Ticket/Display.html?id=65864
310
81984f30
TC
311 - skip the threads tests on Test::More 2.00_*

320 - increase the version of Imager::Font::Type1 so that upgrades don't
321 downgrade the version in this file.
322 https://rt.cpan.org/Ticket/Display.html?id=66250
323
324 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
325 that option for the directories that would normally go in
326 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

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

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

926 - some TGA images weren't being detected correctly as TGA images
927 https://rt.cpan.org/Ticket/Display.html?id=32925
928
929 - handling of the left-over bit for 16-bit/pixel TGA images has been
930 changed to match the behaviour of the GIMP. Previously the bit
931 being set was treated as an opaque pixel, but one user reported a
932 problem with loading such an image. I haven't been able to find any
933 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
934 I'll match it's behaviour. See issue 114913 in the GIMP's
935 bugzilla.

945 - the old dynaload code used Mach API functions to load dynamic
946 libraries on Mac OS X. These APIs have been deprecated in OS X
947 10.5 and were causing some build problems.

949 will need version 10.3 or later of OS X.

1257
1258Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1259
1260There is one new feature:
1261

1263 http://www.cpanforum.com/threads/3276
1264 http://rt.cpan.org/Ticket/Display.html?id=22166
1265
1266Several bugs were fixed:
1267
1268 - the string() method would not output the string "0"
1269 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1270
1271 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1272 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1273
1274 - the gif_disposal and gif_user_input tags weren't being read from
1275 the file correctly
1276 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1277
1278 - gif.c was failing to build under MSVC
1279 http://rt.cpan.org/Ticket/Display.html?id=23922
1280
1281 - in some cases strings passed to the string() method were treated as
1282 terminated by NUL (chr 0)
1283 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1284
1285 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1286 that's the default build name for zlib on Win32.
1287 http://rt.cpan.org/Ticket/Display.html?id=23064
1288
1289 - search $Config{incpath} for headers too, which we should have been
1290 doing all along.
1291
1292Win32 font driver fixes:
1293
1294 - the global descent value from bounding box was the wrong sign
1295 http://www.cpanforum.com/threads/3276
1296

1300
1301Imager 0.54 - 14 Sep 2006
1302===========
1303
1304This is primarily a feature release:
1305
1306 - a new qtype value 'mixing' has been added to the scale()
1307 method. This is faster than 'normal', slower than 'preview'. This
1308 is based on the method used by pnmscale, and seems to produce less
1309 blurry results than normal.
1310 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1311
1312 - the rubthrough() method can now render onto images with an alpha
1313 channel.
1314 http://rt.cpan.org/Ticket/Display.html?id=20678
1315
1316 - the read_multi() method now falls back to calling doing a single
1317 image read via the read() method and write_multi() will now fall
1318 back to calling write() if a single image is supplied. This means
1319 you can simply call the read_multi() or write_multi() functions
1320 without having to check if the type is formatted by that method.
1321 http://rt.cpan.org/Ticket/Display.html?id=19457
1322 http://rt.cpan.org/Ticket/Display.html?id=19458
1323
1324 - the GIF loop extension can now be written. If you don't have
1325 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1326 should upgrade.
1327 http://rt.cpan.org/Ticket/Display.html?id=21185
1328
1329 - getscanline() and setscanline() can now read/write palette index
1330 based data from/to the image for paletted images, by setting type to
1331 'index'.
1332 http://rt.cpan.org/Ticket/Display.html?id=20338
1333
1334 - we no longer hassle you to disable GIF support
1335 http://rt.cpan.org/Ticket/Display.html?id=20687
1336
1337 - minor documentation fixes
1338
1339
1340Imager 0.53 - 26 Jul 2006
1341===========
1342
1343This is a bugfix release.

1351Imager 0.52 - 25 Jul 2006
1352===========
1353
1354This is primarily a feature release, but contains a fair few bug
1355fixes, new features:
1356
1357 - ability to read and write MS Windows ICO and CUR files
1358
1359 - you can now add file format plugins to support new file formats
1360
1361 - add POD coverage tests
1362
1363 - setcolors() and addcolors() now accept color names and so on
1364 instead of requiring Imager::Color objects.
1365 http://rt.cpan.org/Ticket/Display.html?id=20056
1366
1367 - flood_fill() can now fill to a specified border color instead of
1368 just to the area the same color as the seed.
1369 http://rt.cpan.org/Ticket/Display.html?id=19618
1370
1371
1372Bug fixes:
1373
1374 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1375 calculating the advance width.
1376 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1377
1378 - bounding_box for the T1 driver wasn't including leading and
1379 trailing spaces in the bounding box as the other drivers did, it also
1380 produced strange results for empty strings or strings containing only
1381 spaces
1382
1383 - when reading CMYK jpeg images they were being transferred to the
1384 image object as is, producing a four channel image. It only looked ok
1385 due to an old still unfixed Photoshop bug. We now convert from the
1386 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1387 http://rt.cpan.org/Ticket/Display.html?id=20416
1388
1389 - reading a CYMK TIFF would result in a 4 channel image, reading any
1390 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1391 result in an error.
1392 http://rt.cpan.org/Ticket/Display.html?id=20415
1393
1394 - added /usr/local/include to the default include search path, since
1395 we were already searching /usr/local/lib for libraries.
1396
1397And various minor fixes and documentation updates.
