29 - depend on Scalar::Util, since we use it and older perls don't have
30 it.
31
5efba0c6

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

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 63Imager 0.85_01 - 10 Oct 2011
6d5c85a2 64==============
a7e32beb
TC
65
66 - add simple tests for the Imager::Test test_image generators
67
6d5c85a2
TC
68 - io_glue I/O buffering re-work:
69
70 - reorganize io_glue to do it's own buffering by default
71
72 - the unbuffered functions are available as i_io_raw_read() (or
73 raw_read() from perl) etc but are not recommended for typical
74 use.
75
76 - use the new i_io_peekn() when checking for file magic to avoid
77 seek, allowing Imager to detect the file type and read the file
78 from an unseekable stream (for formats that don't use random
79 access)
80
81 - added several new I/O layer API functions.
82
83 - fix the TGA performance problem, most noticably on Win32
84 https://rt.cpan.org/Ticket/Display.html?id=70037
85
86 - TIFF now uses wrapper functions of the correct types to avoid casts
87 https://rt.cpan.org/Ticket/Display.html?id=69912
88
89 - the callback IO object did its own buffering, controlled by the
90 maxbuffer parameter supplied to the read() and write() methods.
91 This buffering has been removed, to avoid redundancy with the
92 common io_glue buffering. This also avoids a bug in that code
93 which could rarely pass a zero length to the read callback and
94 then panic about the result.
95
96 - the callback IO object now tests the result of calling the close
97 callback, which should return true for success.
98
99 - the PNM reader did its own buffering. This buffering has been
100 removed to avoid redundancy with the common io_glue buffering.
101
102 - previously the read handlers for fd and callback I/O layers would
103 call the underlying interface (POSIX read or your supplied callback)
104 until it filled the buffer. It now only makes one call.
105
106 - added public constructors for I/O layer objects (see Imager::IO)
107
108 - all core file handlers now use the i_io_foo() wrappers to gain
109 access to buffered I/O rather than calling the I/O layer
110 callbacks directly.
111
112 - all core file handlers now check for error on close.
113
114 - Backward compatibility: if you hava custom file handlers, you can
115 use i_io_write() etc since they're available as macros in older
116 versions of Imager.
117
118 - eliminate the final remnants of io_glue_commit_types().
119
120 - bump IMAGER_API_VERSION, since the above may break assumptions.
121
122 - removed the long unused i_gen_reader() and i_gen_writer() utility
123 functions.

6ad7e4bc
TC
126===========
127
0c647c9a
TC
128The main changes in the release versus 0.84 are:
129
130 - on 64-bit systems, 64-bit types are consistently used for image
131 dimensions and co-ordinated, and for memory block sizes.
132
133 - handle IFD loops in TIFF files correctly. Previously this would
134 lead to an infinite loop.
135
6ad7e4bc
TC
136Bug fixes:
137
138 - fix the link in the getheight() entry in the method index

143Development release, this will become 0.85 if CPAN testers is
144favourable.
6b7197d0
TC
145
146Bug fixes:
147
148 - the image file limits set by set_file_limits() weren't being
149 checked when reading TIFF files.
150 https://rt.cpan.org/Ticket/Display.html?id=69915
151
5970bd39
TC
152 - Provide more information about file format module load errors on a
153 failed image file read() or write().
154 https://rt.cpan.org/Ticket/Display.html?id=69194
155
4ce3551c
TC
156 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
157 through TIFF images, since it checks for IFD loops.
158 https://rt.cpan.org/Ticket/Display.html?id=69914
159
a16bca6d
TC
160 - don't leak memory when out of range palette indexes are supplied to
161 setscanline().
162 https://rt.cpan.org/Ticket/Display.html?id=69242
163
164 - require a later version of CPAN::Meta to ensure JSON::PP and
165 CPAN::Meta::YAML are available.
166 https://rt.cpan.org/Ticket/Display.html?id=69008
167
ac575c5f
TC
168 - hoist the per-line calculations for the flines implementations, and
169 modernize the tests a bit.
170 https://rt.cpan.org/Ticket/Display.html?id=70126
171
86c8d19a
TC
172 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
173 them when available.

175
a3fd7df7
TC
176 - if t1lib failed to reinitialize it would be left as marked

183Imager 0.84_01 - 8 Aug 2011
184==============
185
186Development release as a sanity check for the types re-work.
8d14daab
TC
187
188Massive types re-work:
189
190 - the type used internally for pixel co-ordinates and image sizes is
191 now 64-bit on 64-bit platforms (at least sane ones).
192
193 - size_t is now used consistently for memory block sizes.
194
195 - since this changes the binary interface, the Imager API version has
196 been incremented. Any module that uses the API will need to be
197 rebuilt. In most cases that will be enough, but calls to any APIs
198 that take a pointer to image sizes may need source changes.
199
200 - you should be able to create very large images on 64-bit systems,
201 if you have enough memory. Successfully created a 32768 x 49192 x
202 3 channel image, filled with a tiled image and scaled it. The
203 unscaled image was also successfully saved to a JPEG.
204
205 - check the image size before attempting to write BMP, GIF, JPEG,
206 PNG, SGI, TGA, TIFF images.
207
208 - correctly handle reading TGA images over 32767 pixels wide or tall.
209
210Incidental changes:
211
212 - the gif_left and gif_top tags are now clamped to non-negative
213 values when writing a GIF image.
214
215 - removed dead callback read/write code
216
217The default maximum memory size when reading files is now 1G.

bd80e51e 219Imager 0.84 - 20 Jun 2011
b1e66a82
TC
220===========
221
222 - Imager no longer inherits from Exporter (unless you're running an
223 old, old perl.
224
92e9df65
TC
225 - Imager can now write progressive JPEGs (it could always read them).

227
10ea52a3
TC
228Bug fixes:
229

243
6d068d36
TC
244 - convert colors to grayscale if the supplied (or generated) palette
245 contains only grays when performing error diffusion color
246 translation.
247 https://rt.cpan.org/Ticket/Display.html?id=68508
248
59c150a4
TC
249 - writing a paletted image to GIF wouldn't always use the colors
250 supplied (or generated, eg. via make_colors => "mono"), which was
251 confusing at best.
252 https://rt.cpan.org/Ticket/Display.html?id=67912
253
5b480b14
TC
254 - replace (imager|tony)@imager.perl.org in the doc, since I don't
255 plan to continue receiving mail at that address.

deb1a916
TC
271
272Bug fixes:
273
274 - Imager::Font::T1 incorrectly checked for absolute filename under
275 Win32. Thanks to kmx for the report and fix.
276 https://rt.cpan.org/Ticket/Display.html?id=67963
277
618a3282
TC
278 - compose() with the target, source or mask position off the top or
279 left of the target image didn't clip the source image correctly.
280 https://rt.cpan.org/Ticket/Display.html?id=67220
281
282 - compose() now returns a useful error message on a non-positive
283 opacity.
284
285 - compose.im now at 100% test coverage. (As opposed to, umm, much,
286 much less.)

2368cfec
TC
289===========
290
291Bug fixes:
292
293 - eliminate calls to i_has_format() from the test suite, since it's
294 no longer a useful way to check for file format support. Eliminate
295 i_has_format() from the functions exposed via XS.
296 https://rt.cpan.org/Ticket/Display.html?id=65863
297
7540f84a
TC
298 - eliminate calls to note(), which isn't in the (very old) version of
299 Test::More we have as a pre-requisite. note() is modern enough
300 that I don't feel a need to require a Test::More upgrade for it.
301 https://rt.cpan.org/Ticket/Display.html?id=65864
302
81984f30
TC
303 - skip the threads tests on Test::More 2.00_*

313 downgrade the version in this file.
314 https://rt.cpan.org/Ticket/Display.html?id=66250
315
316 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
317 that option for the directories that would normally go in
318 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

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

868 https://rt.cpan.org/Ticket/Display.html?id=30908
869
870 - rubthrough() now falls back to pasting when the source doesn't have
871 an alpha channel. This effectively treats the source as having a
872 max alpha channel, the right thing to do.

918 - some TGA images weren't being detected correctly as TGA images
919 https://rt.cpan.org/Ticket/Display.html?id=32925
920
921 - handling of the left-over bit for 16-bit/pixel TGA images has been
922 changed to match the behaviour of the GIMP. Previously the bit
923 being set was treated as an opaque pixel, but one user reported a
924 problem with loading such an image. I haven't been able to find any
925 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
926 I'll match it's behaviour. See issue 114913 in the GIMP's
927 bugzilla.

937 - the old dynaload code used Mach API functions to load dynamic
938 libraries on Mac OS X. These APIs have been deprecated in OS X
939 10.5 and were causing some build problems.
940 So henceforth Imager uses the dlopen() family of functions, and you
941 will need version 10.3 or later of OS X.

1249
1250Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1251
1252There is one new feature:

1256 http://rt.cpan.org/Ticket/Display.html?id=22166
1257
1258Several bugs were fixed:
1259
1260 - the string() method would not output the string "0"
1261 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1262
1263 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1264 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1265
1266 - the gif_disposal and gif_user_input tags weren't being read from
1267 the file correctly
1268 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1269
1270 - gif.c was failing to build under MSVC
1271 http://rt.cpan.org/Ticket/Display.html?id=23922
1272
1273 - in some cases strings passed to the string() method were treated as
1274 terminated by NUL (chr 0)
1275 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1276
1277 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1278 that's the default build name for zlib on Win32.
1279 http://rt.cpan.org/Ticket/Display.html?id=23064
1280
1281 - search $Config{incpath} for headers too, which we should have been
1282 doing all along.
1283
1284Win32 font driver fixes:
1285
1286 - the global descent value from bounding box was the wrong sign
1287 http://www.cpanforum.com/threads/3276
1288
1289 - if the first or last glyph overflowed the left or right side of the
1290 advance width they would be clipped
1291
1292
1293Imager 0.54 - 14 Sep 2006
1294===========
1295
1296This is primarily a feature release:
1297
1298 - a new qtype value 'mixing' has been added to the scale()
1299 method. This is faster than 'normal', slower than 'preview'. This
1300 is based on the method used by pnmscale, and seems to produce less
1301 blurry results than normal.
1302 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1303
1304 - the rubthrough() method can now render onto images with an alpha
1305 channel.
1306 http://rt.cpan.org/Ticket/Display.html?id=20678
1307
1308 - the read_multi() method now falls back to calling doing a single
1309 image read via the read() method and write_multi() will now fall
1310 back to calling write() if a single image is supplied. This means
1311 you can simply call the read_multi() or write_multi() functions
1312 without having to check if the type is formatted by that method.
1313 http://rt.cpan.org/Ticket/Display.html?id=19457
1314 http://rt.cpan.org/Ticket/Display.html?id=19458
1315
1316 - the GIF loop extension can now be written. If you don't have
1317 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1318 should upgrade.
1319 http://rt.cpan.org/Ticket/Display.html?id=21185
1320
1321 - getscanline() and setscanline() can now read/write palette index
1322 based data from/to the image for paletted images, by setting type to
1323 'index'.
1324 http://rt.cpan.org/Ticket/Display.html?id=20338
1325
1326 - we no longer hassle you to disable GIF support
1327 http://rt.cpan.org/Ticket/Display.html?id=20687
1328
1329 - minor documentation fixes
1330

1346This is primarily a feature release, but contains a fair few bug
1347fixes, new features:
1348
1349 - ability to read and write MS Windows ICO and CUR files
1350
1351 - you can now add file format plugins to support new file formats
1352
1353 - add POD coverage tests
1354
1355 - setcolors() and addcolors() now accept color names and so on
1356 instead of requiring Imager::Color objects.
1357 http://rt.cpan.org/Ticket/Display.html?id=20056
1358
1359 - flood_fill() can now fill to a specified border color instead of
1360 just to the area the same color as the seed.

1362
1363
1364Bug fixes:
1365
1366 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1367 calculating the advance width.
1368 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1369
1370 - bounding_box for the T1 driver wasn't including leading and
1371 trailing spaces in the bounding box as the other drivers did, it also
1372 produced strange results for empty strings or strings containing only
1373 spaces
1374
1375 - when reading CMYK jpeg images they were being transferred to the
1376 image object as is, producing a four channel image. It only looked ok
1377 due to an old still unfixed Photoshop bug. We now convert from the
1378 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1379 http://rt.cpan.org/Ticket/Display.html?id=20416
1380
1381 - reading a CYMK TIFF would result in a 4 channel image, reading any
1382 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1383 result in an error.
1384 http://rt.cpan.org/Ticket/Display.html?id=20415
1385
1386 - added /usr/local/include to the default include search path, since
1387 we were already searching /usr/local/lib for libraries.
1388
