48 creation.
49
50 - Imager::Font->new now produces better error messages for the T1
51 engine.
52
6e938c74
TC
53 - the font has_chars() method now returns perl's true and false
54 values in list context rather than integers, which should be more
55 efficient.

TC
72 - we rely on Config.pm's d_vsnprintf as to whether we use
73 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
74 though it only has _ prefixed versions of these. Define our own
75 prefixed names on Win32.

6d5c85a2 85==============
a7e32beb
TC
86
87 - add simple tests for the Imager::Test test_image generators
88
6d5c85a2
TC
89 - io_glue I/O buffering re-work:
90
91 - reorganize io_glue to do it's own buffering by default
92
93 - the unbuffered functions are available as i_io_raw_read() (or
94 raw_read() from perl) etc but are not recommended for typical
95 use.
96
97 - use the new i_io_peekn() when checking for file magic to avoid
98 seek, allowing Imager to detect the file type and read the file
99 from an unseekable stream (for formats that don't use random
100 access)
101
102 - added several new I/O layer API functions.
103
104 - fix the TGA performance problem, most noticably on Win32
105 https://rt.cpan.org/Ticket/Display.html?id=70037
106
107 - TIFF now uses wrapper functions of the correct types to avoid casts
108 https://rt.cpan.org/Ticket/Display.html?id=69912
109
110 - the callback IO object did its own buffering, controlled by the
111 maxbuffer parameter supplied to the read() and write() methods.
112 This buffering has been removed, to avoid redundancy with the
113 common io_glue buffering. This also avoids a bug in that code
114 which could rarely pass a zero length to the read callback and
115 then panic about the result.
116
117 - the callback IO object now tests the result of calling the close
118 callback, which should return true for success.
119
120 - the PNM reader did its own buffering. This buffering has been
121 removed to avoid redundancy with the common io_glue buffering.
122
123 - previously the read handlers for fd and callback I/O layers would
124 call the underlying interface (POSIX read or your supplied callback)
125 until it filled the buffer. It now only makes one call.
126
127 - added public constructors for I/O layer objects (see Imager::IO)
128
129 - all core file handlers now use the i_io_foo() wrappers to gain
130 access to buffered I/O rather than calling the I/O layer
131 callbacks directly.
132
133 - all core file handlers now check for error on close.
134
135 - Backward compatibility: if you hava custom file handlers, you can
136 use i_io_write() etc since they're available as macros in older
137 versions of Imager.
138
139 - eliminate the final remnants of io_glue_commit_types().
140
141 - bump IMAGER_API_VERSION, since the above may break assumptions.
142
143 - removed the long unused i_gen_reader() and i_gen_writer() utility
144 functions.

6ad7e4bc
TC
147===========
148
0c647c9a
TC
149The main changes in the release versus 0.84 are:
150
151 - on 64-bit systems, 64-bit types are consistently used for image
152 dimensions and co-ordinated, and for memory block sizes.
153
154 - handle IFD loops in TIFF files correctly. Previously this would
155 lead to an infinite loop.
156
6ad7e4bc
TC
157Bug fixes:
158
159 - fix the link in the getheight() entry in the method index

164Development release, this will become 0.85 if CPAN testers is
165favourable.
6b7197d0
TC
166
167Bug fixes:
168
169 - the image file limits set by set_file_limits() weren't being
170 checked when reading TIFF files.
171 https://rt.cpan.org/Ticket/Display.html?id=69915
172
5970bd39
TC
173 - Provide more information about file format module load errors on a
174 failed image file read() or write().
175 https://rt.cpan.org/Ticket/Display.html?id=69194
176
4ce3551c
TC
177 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
178 through TIFF images, since it checks for IFD loops.
179 https://rt.cpan.org/Ticket/Display.html?id=69914
180
a16bca6d
TC
181 - don't leak memory when out of range palette indexes are supplied to
182 setscanline().
183 https://rt.cpan.org/Ticket/Display.html?id=69242
184
185 - require a later version of CPAN::Meta to ensure JSON::PP and
186 CPAN::Meta::YAML are available.
187 https://rt.cpan.org/Ticket/Display.html?id=69008
188
ac575c5f
TC
189 - hoist the per-line calculations for the flines implementations, and
190 modernize the tests a bit.
191 https://rt.cpan.org/Ticket/Display.html?id=70126
192
86c8d19a
TC
193 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
194 them when available.
195 https://rt.cpan.org/Ticket/Display.html?id=69147
196
a3fd7df7
TC
197 - if t1lib failed to reinitialize it would be left as marked

204Imager 0.84_01 - 8 Aug 2011
205==============
206
207Development release as a sanity check for the types re-work.
8d14daab
TC
208
209Massive types re-work:
210
211 - the type used internally for pixel co-ordinates and image sizes is
212 now 64-bit on 64-bit platforms (at least sane ones).
213
214 - size_t is now used consistently for memory block sizes.
215
216 - since this changes the binary interface, the Imager API version has
217 been incremented. Any module that uses the API will need to be
218 rebuilt. In most cases that will be enough, but calls to any APIs
219 that take a pointer to image sizes may need source changes.
220
221 - you should be able to create very large images on 64-bit systems,
222 if you have enough memory. Successfully created a 32768 x 49192 x
223 3 channel image, filled with a tiled image and scaled it. The
224 unscaled image was also successfully saved to a JPEG.
225
226 - check the image size before attempting to write BMP, GIF, JPEG,
227 PNG, SGI, TGA, TIFF images.
228
229 - correctly handle reading TGA images over 32767 pixels wide or tall.
230
231Incidental changes:
232
233 - the gif_left and gif_top tags are now clamped to non-negative
234 values when writing a GIF image.
235
236 - removed dead callback read/write code
237
238The default maximum memory size when reading files is now 1G.

b1e66a82
TC
241===========
242
243 - Imager no longer inherits from Exporter (unless you're running an
244 old, old perl.
245
92e9df65
TC
246 - Imager can now write progressive JPEGs (it could always read them).

TC
249Bug fixes:

263 https://rt.cpan.org/Ticket/Display.html?id=65228
264
6d068d36
TC
265 - convert colors to grayscale if the supplied (or generated) palette
266 contains only grays when performing error diffusion color
267 translation.
268 https://rt.cpan.org/Ticket/Display.html?id=68508
269
59c150a4
TC
270 - writing a paletted image to GIF wouldn't always use the colors
271 supplied (or generated, eg. via make_colors => "mono"), which was
272 confusing at best.
273 https://rt.cpan.org/Ticket/Display.html?id=67912
274
5b480b14
TC
275 - replace (imager|tony)@imager.perl.org in the doc, since I don't

292
293Bug fixes:
294

296 Win32. Thanks to kmx for the report and fix.
297 https://rt.cpan.org/Ticket/Display.html?id=67963
298
618a3282
TC
299 - compose() with the target, source or mask position off the top or
300 left of the target image didn't clip the source image correctly.
301 https://rt.cpan.org/Ticket/Display.html?id=67220
302
303 - compose() now returns a useful error message on a non-positive
304 opacity.
305
306 - compose.im now at 100% test coverage. (As opposed to, umm, much,
307 much less.)

2368cfec
TC
310===========
311
312Bug fixes:
313
314 - eliminate calls to i_has_format() from the test suite, since it's
315 no longer a useful way to check for file format support. Eliminate
316 i_has_format() from the functions exposed via XS.
317 https://rt.cpan.org/Ticket/Display.html?id=65863
318
7540f84a
TC
319 - eliminate calls to note(), which isn't in the (very old) version of
320 Test::More we have as a pre-requisite. note() is modern enough
321 that I don't feel a need to require a Test::More upgrade for it.
322 https://rt.cpan.org/Ticket/Display.html?id=65864
323
81984f30

333 - increase the version of Imager::Font::Type1 so that upgrades don't
334 downgrade the version in this file.
335 https://rt.cpan.org/Ticket/Display.html?id=66250
336
337 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
338 that option for the directories that would normally go in
339 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

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

413 - add Imager::Test to the POD coverage tests and document the missing
414 functions.
415
2a2c791f
TC
416 - the convert() method now optimizes the case where all output
417 channels are either 0, sourced from a single input channel or 1.
418 This significantly speeds up presets like "addalpha", "green".
419 https://rt.cpan.org/Ticket/Display.html?id=51254

874This release primarily contains changes to improve ease of use -

888 noalpha channels or back.
889 https://rt.cpan.org/Ticket/Display.html?id=30908
890
891 - rubthrough() now falls back to pasting when the source doesn't have
892 an alpha channel. This effectively treats the source as having a
893 max alpha channel, the right thing to do.

900 defines them with respect to a translucent source and destination.

939 - some TGA images weren't being detected correctly as TGA images
940 https://rt.cpan.org/Ticket/Display.html?id=32925
941
942 - handling of the left-over bit for 16-bit/pixel TGA images has been
943 changed to match the behaviour of the GIMP. Previously the bit
944 being set was treated as an opaque pixel, but one user reported a
945 problem with loading such an image. I haven't been able to find any
946 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
947 I'll match it's behaviour. See issue 114913 in the GIMP's
948 bugzilla.

1270
1271Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1272
1273There is one new feature:
1274
1275 - the Win32 font driver now supports UTF8 (RT 22166)
1276 http://www.cpanforum.com/threads/3276
1277 http://rt.cpan.org/Ticket/Display.html?id=22166
1278
1279Several bugs were fixed:
1280
1281 - the string() method would not output the string "0"
1282 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1283
1284 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1285 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1286
1287 - the gif_disposal and gif_user_input tags weren't being read from
1288 the file correctly
1289 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1290
1291 - gif.c was failing to build under MSVC
1292 http://rt.cpan.org/Ticket/Display.html?id=23922
1293
1294 - in some cases strings passed to the string() method were treated as
1295 terminated by NUL (chr 0)
1296 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1297
1298 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1299 that's the default build name for zlib on Win32.
1300 http://rt.cpan.org/Ticket/Display.html?id=23064
1301
1302 - search $Config{incpath} for headers too, which we should have been
1303 doing all along.
1304
1305Win32 font driver fixes:
1306
1307 - the global descent value from bounding box was the wrong sign
1308 http://www.cpanforum.com/threads/3276
1309
1310 - if the first or last glyph overflowed the left or right side of the
1311 advance width they would be clipped
1312
1313
1314Imager 0.54 - 14 Sep 2006
1315===========
1316
1317This is primarily a feature release:
1318
1319 - a new qtype value 'mixing' has been added to the scale()
1320 method. This is faster than 'normal', slower than 'preview'. This
1321 is based on the method used by pnmscale, and seems to produce less
1322 blurry results than normal.
1323 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1324
1325 - the rubthrough() method can now render onto images with an alpha
1326 channel.
1327 http://rt.cpan.org/Ticket/Display.html?id=20678
1328
1329 - the read_multi() method now falls back to calling doing a single
1330 image read via the read() method and write_multi() will now fall
1331 back to calling write() if a single image is supplied. This means
1332 you can simply call the read_multi() or write_multi() functions
1333 without having to check if the type is formatted by that method.
1334 http://rt.cpan.org/Ticket/Display.html?id=19457
1335 http://rt.cpan.org/Ticket/Display.html?id=19458
1336
1337 - the GIF loop extension can now be written. If you don't have
1338 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1339 should upgrade.
1340 http://rt.cpan.org/Ticket/Display.html?id=21185
1341
1342 - getscanline() and setscanline() can now read/write palette index
1343 based data from/to the image for paletted images, by setting type to
1344 'index'.
1345 http://rt.cpan.org/Ticket/Display.html?id=20338
1346

1354===========
1355
1356This is a bugfix release.
1357

1364Imager 0.52 - 25 Jul 2006
1365===========
1366
1367This is primarily a feature release, but contains a fair few bug
1368fixes, new features:
1369
1370 - ability to read and write MS Windows ICO and CUR files
1371
1372 - you can now add file format plugins to support new file formats
1373
1374 - add POD coverage tests
1375
1376 - setcolors() and addcolors() now accept color names and so on
1377 instead of requiring Imager::Color objects.
1378 http://rt.cpan.org/Ticket/Display.html?id=20056
1379
1380 - flood_fill() can now fill to a specified border color instead of
1381 just to the area the same color as the seed.
1382 http://rt.cpan.org/Ticket/Display.html?id=19618
1383
1384
1385Bug fixes:
1386
1387 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1388 calculating the advance width.
1389 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1390
1391 - bounding_box for the T1 driver wasn't including leading and
1392 trailing spaces in the bounding box as the other drivers did, it also
1393 produced strange results for empty strings or strings containing only
1394 spaces
1395
1396 - when reading CMYK jpeg images they were being transferred to the
1397 image object as is, producing a four channel image. It only looked ok
1398 due to an old still unfixed Photoshop bug. We now convert from the
1399 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1400 http://rt.cpan.org/Ticket/Display.html?id=20416
1401
1402 - reading a CYMK TIFF would result in a 4 channel image, reading any
1403 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1404 result in an error.
1405 http://rt.cpan.org/Ticket/Display.html?id=20415
1406
1407 - added /usr/local/include to the default include search path, since
1408 we were already searching /usr/local/lib for libraries.
1409
1410And various minor fixes and documentation updates.
