34 - depend on Scalar::Util, since we use it and older perls don't have
35 it.
36
5efba0c6

40 - use T1_StrError() for error messages on modern libt1
41 https://rt.cpan.org/Ticket/Display.html?id=69879

44 creation.
45
46 - Imager::Font->new now produces better error messages for the T1
47 engine.
48
6e938c74
TC
49 - the font has_chars() method now returns perl's true and false
50 values in list context rather than integers, which should be more
51 efficient.

67
336ce474
TC
68 - we rely on Config.pm's d_vsnprintf as to whether we use
69 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
70 though it only has _ prefixed versions of these. Define our own
71 prefixed names on Win32.

31be6e9a 80Imager 0.85_01 - 10 Oct 2011
6d5c85a2 81==============
a7e32beb
TC
82
83 - add simple tests for the Imager::Test test_image generators
84
6d5c85a2
TC
85 - io_glue I/O buffering re-work:
86
87 - reorganize io_glue to do it's own buffering by default
88
89 - the unbuffered functions are available as i_io_raw_read() (or
90 raw_read() from perl) etc but are not recommended for typical
91 use.
92
93 - use the new i_io_peekn() when checking for file magic to avoid
94 seek, allowing Imager to detect the file type and read the file
95 from an unseekable stream (for formats that don't use random
96 access)
97
98 - added several new I/O layer API functions.
99
100 - fix the TGA performance problem, most noticably on Win32
101 https://rt.cpan.org/Ticket/Display.html?id=70037
102
103 - TIFF now uses wrapper functions of the correct types to avoid casts
104 https://rt.cpan.org/Ticket/Display.html?id=69912
105
106 - the callback IO object did its own buffering, controlled by the
107 maxbuffer parameter supplied to the read() and write() methods.
108 This buffering has been removed, to avoid redundancy with the
109 common io_glue buffering. This also avoids a bug in that code
110 which could rarely pass a zero length to the read callback and
111 then panic about the result.
112
113 - the callback IO object now tests the result of calling the close
114 callback, which should return true for success.
115
116 - the PNM reader did its own buffering. This buffering has been
117 removed to avoid redundancy with the common io_glue buffering.
118
119 - previously the read handlers for fd and callback I/O layers would
120 call the underlying interface (POSIX read or your supplied callback)
121 until it filled the buffer. It now only makes one call.
122
123 - added public constructors for I/O layer objects (see Imager::IO)
124
125 - all core file handlers now use the i_io_foo() wrappers to gain
126 access to buffered I/O rather than calling the I/O layer
127 callbacks directly.
128
129 - all core file handlers now check for error on close.
130
131 - Backward compatibility: if you hava custom file handlers, you can
132 use i_io_write() etc since they're available as macros in older
133 versions of Imager.
134
135 - eliminate the final remnants of io_glue_commit_types().
136
137 - bump IMAGER_API_VERSION, since the above may break assumptions.
138
139 - removed the long unused i_gen_reader() and i_gen_writer() utility
140 functions.

6ad7e4bc
TC
143===========
144
0c647c9a
TC
145The main changes in the release versus 0.84 are:
146
147 - on 64-bit systems, 64-bit types are consistently used for image
148 dimensions and co-ordinated, and for memory block sizes.
149
150 - handle IFD loops in TIFF files correctly. Previously this would
151 lead to an infinite loop.
152
6ad7e4bc
TC
153Bug fixes:
154
155 - fix the link in the getheight() entry in the method index

161favourable.
6b7197d0
TC
162
163Bug fixes:
164
165 - the image file limits set by set_file_limits() weren't being
166 checked when reading TIFF files.
167 https://rt.cpan.org/Ticket/Display.html?id=69915
168
5970bd39
TC
169 - Provide more information about file format module load errors on a
170 failed image file read() or write().
171 https://rt.cpan.org/Ticket/Display.html?id=69194
172
4ce3551c
TC
173 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
174 through TIFF images, since it checks for IFD loops.
175 https://rt.cpan.org/Ticket/Display.html?id=69914
176
a16bca6d
TC
177 - don't leak memory when out of range palette indexes are supplied to
178 setscanline().
179 https://rt.cpan.org/Ticket/Display.html?id=69242
180
181 - require a later version of CPAN::Meta to ensure JSON::PP and
182 CPAN::Meta::YAML are available.
183 https://rt.cpan.org/Ticket/Display.html?id=69008
184
ac575c5f
TC
185 - hoist the per-line calculations for the flines implementations, and
186 modernize the tests a bit.
187 https://rt.cpan.org/Ticket/Display.html?id=70126
188
86c8d19a
TC
189 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
190 them when available.
191 https://rt.cpan.org/Ticket/Display.html?id=69147
192
a3fd7df7
TC
193 - if t1lib failed to reinitialize it would be left as marked

200Imager 0.84_01 - 8 Aug 2011
201==============
202
203Development release as a sanity check for the types re-work.
8d14daab
TC
204
205Massive types re-work:
206
207 - the type used internally for pixel co-ordinates and image sizes is
208 now 64-bit on 64-bit platforms (at least sane ones).
209
210 - size_t is now used consistently for memory block sizes.
211
212 - since this changes the binary interface, the Imager API version has
213 been incremented. Any module that uses the API will need to be
214 rebuilt. In most cases that will be enough, but calls to any APIs
215 that take a pointer to image sizes may need source changes.
216
217 - you should be able to create very large images on 64-bit systems,
218 if you have enough memory. Successfully created a 32768 x 49192 x
219 3 channel image, filled with a tiled image and scaled it. The
220 unscaled image was also successfully saved to a JPEG.
221
222 - check the image size before attempting to write BMP, GIF, JPEG,
223 PNG, SGI, TGA, TIFF images.
224
225 - correctly handle reading TGA images over 32767 pixels wide or tall.
226
227Incidental changes:
228
229 - the gif_left and gif_top tags are now clamped to non-negative
230 values when writing a GIF image.
231
232 - removed dead callback read/write code
233
234The default maximum memory size when reading files is now 1G.

b1e66a82
TC
237===========
238
239 - Imager no longer inherits from Exporter (unless you're running an
240 old, old perl.
241
92e9df65
TC
242 - Imager can now write progressive JPEGs (it could always read them).
243 https://rt.cpan.org/Ticket/Display.html?id=68691
244
10ea52a3
TC
245Bug fixes:
246
247 - re-work, document and test Imager's logging facility.

260
6d068d36
TC
261 - convert colors to grayscale if the supplied (or generated) palette
262 contains only grays when performing error diffusion color
263 translation.
264 https://rt.cpan.org/Ticket/Display.html?id=68508
265
59c150a4
TC
266 - writing a paletted image to GIF wouldn't always use the colors
267 supplied (or generated, eg. via make_colors => "mono"), which was
268 confusing at best.
269 https://rt.cpan.org/Ticket/Display.html?id=67912
270
5b480b14
TC
271 - replace (imager|tony)@imager.perl.org in the doc, since I don't

deb1a916
TC
288
289Bug fixes:
290
291 - Imager::Font::T1 incorrectly checked for absolute filename under
292 Win32. Thanks to kmx for the report and fix.
293 https://rt.cpan.org/Ticket/Display.html?id=67963
294
618a3282
TC
295 - compose() with the target, source or mask position off the top or
296 left of the target image didn't clip the source image correctly.
297 https://rt.cpan.org/Ticket/Display.html?id=67220
298
299 - compose() now returns a useful error message on a non-positive
300 opacity.
301
302 - compose.im now at 100% test coverage. (As opposed to, umm, much,
303 much less.)

c1d16c8f 305Imager 0.82 - 14 Mar 2011
2368cfec
TC
306===========
307
308Bug fixes:
309
310 - eliminate calls to i_has_format() from the test suite, since it's
311 no longer a useful way to check for file format support. Eliminate
312 i_has_format() from the functions exposed via XS.
313 https://rt.cpan.org/Ticket/Display.html?id=65863
314
7540f84a
TC
315 - eliminate calls to note(), which isn't in the (very old) version of
316 Test::More we have as a pre-requisite. note() is modern enough
317 that I don't feel a need to require a Test::More upgrade for it.
318 https://rt.cpan.org/Ticket/Display.html?id=65864
319
81984f30
TC
320 - skip the threads tests on Test::More 2.00_*

329 - increase the version of Imager::Font::Type1 so that upgrades don't
330 downgrade the version in this file.
331 https://rt.cpan.org/Ticket/Display.html?id=66250
332
333 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
334 that option for the directories that would normally go in
335 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

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

409 - add Imager::Test to the POD coverage tests and document the missing
410 functions.
411
2a2c791f
TC
412 - the convert() method now optimizes the case where all output
413 channels are either 0, sourced from a single input channel or 1.
414 This significantly speeds up presets like "addalpha", "green".
415 https://rt.cpan.org/Ticket/Display.html?id=51254

935 - some TGA images weren't being detected correctly as TGA images
936 https://rt.cpan.org/Ticket/Display.html?id=32925
937
938 - handling of the left-over bit for 16-bit/pixel TGA images has been
939 changed to match the behaviour of the GIMP. Previously the bit
940 being set was treated as an opaque pixel, but one user reported a
941 problem with loading such an image. I haven't been able to find any
942 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
943 I'll match it's behaviour. See issue 114913 in the GIMP's
944 bugzilla.

1267Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1268
1269There is one new feature:

1273 http://rt.cpan.org/Ticket/Display.html?id=22166

1276
1277 - the string() method would not output the string "0"
1278 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1279
1280 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1281 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1282
1283 - the gif_disposal and gif_user_input tags weren't being read from
1284 the file correctly
1285 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1286
1287 - gif.c was failing to build under MSVC
1288 http://rt.cpan.org/Ticket/Display.html?id=23922
1289
1290 - in some cases strings passed to the string() method were treated as
1291 terminated by NUL (chr 0)
1292 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1293
1294 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1295 that's the default build name for zlib on Win32.
1296 http://rt.cpan.org/Ticket/Display.html?id=23064
1297
1298 - search $Config{incpath} for headers too, which we should have been
1299 doing all along.
1300
1301Win32 font driver fixes:
1302
1303 - the global descent value from bounding box was the wrong sign
1304 http://www.cpanforum.com/threads/3276
1305

1307 advance width they would be clipped
1308
1309
1310Imager 0.54 - 14 Sep 2006
1311===========
1312
1313This is primarily a feature release:
1314
1315 - a new qtype value 'mixing' has been added to the scale()
1316 method. This is faster than 'normal', slower than 'preview'. This
1317 is based on the method used by pnmscale, and seems to produce less
1318 blurry results than normal.
1319 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1320
1321 - the rubthrough() method can now render onto images with an alpha
1322 channel.
1323 http://rt.cpan.org/Ticket/Display.html?id=20678
1324
1325 - the read_multi() method now falls back to calling doing a single
1326 image read via the read() method and write_multi() will now fall
1327 back to calling write() if a single image is supplied. This means
1328 you can simply call the read_multi() or write_multi() functions
1329 without having to check if the type is formatted by that method.
1330 http://rt.cpan.org/Ticket/Display.html?id=19457
1331 http://rt.cpan.org/Ticket/Display.html?id=19458
1332
1333 - the GIF loop extension can now be written. If you don't have
1334 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1335 should upgrade.
1336 http://rt.cpan.org/Ticket/Display.html?id=21185
1337
1338 - getscanline() and setscanline() can now read/write palette index

1360Imager 0.52 - 25 Jul 2006
1361===========
1362
1363This is primarily a feature release, but contains a fair few bug
1364fixes, new features:
1365
1366 - ability to read and write MS Windows ICO and CUR files
1367
1368 - you can now add file format plugins to support new file formats
1369
1370 - add POD coverage tests
1371
1372 - setcolors() and addcolors() now accept color names and so on
1373 instead of requiring Imager::Color objects.
1374 http://rt.cpan.org/Ticket/Display.html?id=20056
1375
1376 - flood_fill() can now fill to a specified border color instead of
1377 just to the area the same color as the seed.
1378 http://rt.cpan.org/Ticket/Display.html?id=19618
1379
1380
1381Bug fixes:
1382
1383 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1384 calculating the advance width.
1385 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1386
1387 - bounding_box for the T1 driver wasn't including leading and
1388 trailing spaces in the bounding box as the other drivers did, it also
1389 produced strange results for empty strings or strings containing only
1390 spaces
1391
1392 - when reading CMYK jpeg images they were being transferred to the
1393 image object as is, producing a four channel image. It only looked ok
1394 due to an old still unfixed Photoshop bug. We now convert from the
1395 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1396 http://rt.cpan.org/Ticket/Display.html?id=20416
1397
1398 - reading a CYMK TIFF would result in a 4 channel image, reading any
1399 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1400 result in an error.
1401 http://rt.cpan.org/Ticket/Display.html?id=20415
1402
1403 - added /usr/local/include to the default include search path, since
1404 we were already searching /usr/local/lib for libraries.
1405
1406And various minor fixes and documentation updates.
