31 - depend on Scalar::Util, since we use it and older perls don't have
32 it.
33
5efba0c6
TC
34 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
35 to synthesize it from overloaded "".
36

TC
37 - use T1_StrError() for error messages on modern libt1
38 https://rt.cpan.org/Ticket/Display.html?id=69879
39
40 - actually load the font rather than just adding it to the catalog on
41 creation.
42
43 - Imager::Font->new now produces better error messages for the T1
44 engine.
45
6e938c74
TC
46 - the font has_chars() method now returns perl's true and false
47 values in list context rather than integers, which should be more
48 efficient.

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

6d5c85a2 78==============
a7e32beb
TC
79
80 - add simple tests for the Imager::Test test_image generators
81
6d5c85a2
TC
82 - io_glue I/O buffering re-work:
83
84 - reorganize io_glue to do it's own buffering by default
85
86 - the unbuffered functions are available as i_io_raw_read() (or
87 raw_read() from perl) etc but are not recommended for typical
88 use.
89
90 - use the new i_io_peekn() when checking for file magic to avoid
91 seek, allowing Imager to detect the file type and read the file
92 from an unseekable stream (for formats that don't use random
93 access)
94
95 - added several new I/O layer API functions.
96
97 - fix the TGA performance problem, most noticably on Win32
98 https://rt.cpan.org/Ticket/Display.html?id=70037
99
100 - TIFF now uses wrapper functions of the correct types to avoid casts
101 https://rt.cpan.org/Ticket/Display.html?id=69912
102
103 - the callback IO object did its own buffering, controlled by the
104 maxbuffer parameter supplied to the read() and write() methods.
105 This buffering has been removed, to avoid redundancy with the
106 common io_glue buffering. This also avoids a bug in that code
107 which could rarely pass a zero length to the read callback and
108 then panic about the result.
109
110 - the callback IO object now tests the result of calling the close
111 callback, which should return true for success.
112
113 - the PNM reader did its own buffering. This buffering has been
114 removed to avoid redundancy with the common io_glue buffering.
115
116 - previously the read handlers for fd and callback I/O layers would
117 call the underlying interface (POSIX read or your supplied callback)
118 until it filled the buffer. It now only makes one call.
119
120 - added public constructors for I/O layer objects (see Imager::IO)
121
122 - all core file handlers now use the i_io_foo() wrappers to gain
123 access to buffered I/O rather than calling the I/O layer
124 callbacks directly.
125
126 - all core file handlers now check for error on close.
127
128 - Backward compatibility: if you hava custom file handlers, you can
129 use i_io_write() etc since they're available as macros in older
130 versions of Imager.
131
132 - eliminate the final remnants of io_glue_commit_types().
133
134 - bump IMAGER_API_VERSION, since the above may break assumptions.
135
136 - removed the long unused i_gen_reader() and i_gen_writer() utility
137 functions.

TC
140===========
141
0c647c9a
TC
142The main changes in the release versus 0.84 are:
143
144 - on 64-bit systems, 64-bit types are consistently used for image
145 dimensions and co-ordinated, and for memory block sizes.
146
147 - handle IFD loops in TIFF files correctly. Previously this would
148 lead to an infinite loop.
149
6ad7e4bc
TC
150Bug fixes:
151
152 - fix the link in the getheight() entry in the method index

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

189
a3fd7df7
TC
190 - if t1lib failed to reinitialize it would be left as marked

197Imager 0.84_01 - 8 Aug 2011
198==============
199
200Development release as a sanity check for the types re-work.
8d14daab
TC
201
202Massive types re-work:
203
204 - the type used internally for pixel co-ordinates and image sizes is
205 now 64-bit on 64-bit platforms (at least sane ones).
206
207 - size_t is now used consistently for memory block sizes.
208
209 - since this changes the binary interface, the Imager API version has
210 been incremented. Any module that uses the API will need to be
211 rebuilt. In most cases that will be enough, but calls to any APIs
212 that take a pointer to image sizes may need source changes.
213
214 - you should be able to create very large images on 64-bit systems,
215 if you have enough memory. Successfully created a 32768 x 49192 x
216 3 channel image, filled with a tiled image and scaled it. The
217 unscaled image was also successfully saved to a JPEG.
218
219 - check the image size before attempting to write BMP, GIF, JPEG,
220 PNG, SGI, TGA, TIFF images.
221
222 - correctly handle reading TGA images over 32767 pixels wide or tall.
223
224Incidental changes:
225
226 - the gif_left and gif_top tags are now clamped to non-negative
227 values when writing a GIF image.
228
229 - removed dead callback read/write code
230
231The default maximum memory size when reading files is now 1G.

TC
234===========
235
236 - Imager no longer inherits from Exporter (unless you're running an
237 old, old perl.
238
92e9df65
TC
239 - Imager can now write progressive JPEGs (it could always read them).

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

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

2368cfec
TC
303===========
304
305Bug fixes:
306
307 - eliminate calls to i_has_format() from the test suite, since it's
308 no longer a useful way to check for file format support. Eliminate
309 i_has_format() from the functions exposed via XS.
310 https://rt.cpan.org/Ticket/Display.html?id=65863
311
7540f84a
TC
312 - eliminate calls to note(), which isn't in the (very old) version of
313 Test::More we have as a pre-requisite. note() is modern enough
314 that I don't feel a need to require a Test::More upgrade for it.
315 https://rt.cpan.org/Ticket/Display.html?id=65864
316
81984f30

327 downgrade the version in this file.
328 https://rt.cpan.org/Ticket/Display.html?id=66250
329
330 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
331 that option for the directories that would normally go in
332 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

409 - the convert() method now optimizes the case where all output
410 channels are either 0, sourced from a single input channel or 1.
411 This significantly speeds up presets like "addalpha", "green".
412 https://rt.cpan.org/Ticket/Display.html?id=51254

882 https://rt.cpan.org/Ticket/Display.html?id=30908
883
884 - rubthrough() now falls back to pasting when the source doesn't have
885 an alpha channel. This effectively treats the source as having a
886 max alpha channel, the right thing to do.

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

951 - the old dynaload code used Mach API functions to load dynamic
952 libraries on Mac OS X. These APIs have been deprecated in OS X
953 10.5 and were causing some build problems.
954 So henceforth Imager uses the dlopen() family of functions, and you
955 will need version 10.3 or later of OS X.

1262This is primarily a bug fix release.
1263
1264Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1265
1266There is one new feature:
1267
1268 - the Win32 font driver now supports UTF8 (RT 22166)

1270 http://rt.cpan.org/Ticket/Display.html?id=22166

1272Several bugs were fixed:
1273
1274 - the string() method would not output the string "0"
1275 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1276
1277 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1278 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1279
1280 - the gif_disposal and gif_user_input tags weren't being read from
1281 the file correctly
1282 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1283
1284 - gif.c was failing to build under MSVC
1285 http://rt.cpan.org/Ticket/Display.html?id=23922
1286
1287 - in some cases strings passed to the string() method were treated as
1288 terminated by NUL (chr 0)
1289 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1290
1291 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1292 that's the default build name for zlib on Win32.
1293 http://rt.cpan.org/Ticket/Display.html?id=23064
1294
1295 - search $Config{incpath} for headers too, which we should have been
1296 doing all along.
1297
1298Win32 font driver fixes:
1299
1300 - the global descent value from bounding box was the wrong sign
1301 http://www.cpanforum.com/threads/3276
1302
1303 - if the first or last glyph overflowed the left or right side of the
1304 advance width they would be clipped

1306
1307Imager 0.54 - 14 Sep 2006
1308===========
1309
1310This is primarily a feature release:
1311
1312 - a new qtype value 'mixing' has been added to the scale()
1313 method. This is faster than 'normal', slower than 'preview'. This
1314 is based on the method used by pnmscale, and seems to produce less
1315 blurry results than normal.
1316 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1317
1318 - the rubthrough() method can now render onto images with an alpha
1319 channel.
1320 http://rt.cpan.org/Ticket/Display.html?id=20678
1321
1322 - the read_multi() method now falls back to calling doing a single
1323 image read via the read() method and write_multi() will now fall
1324 back to calling write() if a single image is supplied. This means
1325 you can simply call the read_multi() or write_multi() functions
1326 without having to check if the type is formatted by that method.
1327 http://rt.cpan.org/Ticket/Display.html?id=19457
1328 http://rt.cpan.org/Ticket/Display.html?id=19458
1329
1330 - the GIF loop extension can now be written. If you don't have
1331 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1332 should upgrade.
1333 http://rt.cpan.org/Ticket/Display.html?id=21185
1334
1335 - getscanline() and setscanline() can now read/write palette index
1336 based data from/to the image for paletted images, by setting type to
1337 'index'.
1338 http://rt.cpan.org/Ticket/Display.html?id=20338

1357Imager 0.52 - 25 Jul 2006
1358===========
1359
1360This is primarily a feature release, but contains a fair few bug
1361fixes, new features:
1362
1363 - ability to read and write MS Windows ICO and CUR files
1364
1365 - you can now add file format plugins to support new file formats
1366
1367 - add POD coverage tests
1368
1369 - setcolors() and addcolors() now accept color names and so on
1370 instead of requiring Imager::Color objects.
1371 http://rt.cpan.org/Ticket/Display.html?id=20056
1372
1373 - flood_fill() can now fill to a specified border color instead of
1374 just to the area the same color as the seed.
1375 http://rt.cpan.org/Ticket/Display.html?id=19618
1376
1377
1378Bug fixes:
1379
1380 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1381 calculating the advance width.
1382 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1383
1384 - bounding_box for the T1 driver wasn't including leading and
1385 trailing spaces in the bounding box as the other drivers did, it also
1386 produced strange results for empty strings or strings containing only
1387 spaces
1388
1389 - when reading CMYK jpeg images they were being transferred to the
1390 image object as is, producing a four channel image. It only looked ok
1391 due to an old still unfixed Photoshop bug. We now convert from the
1392 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1393 http://rt.cpan.org/Ticket/Display.html?id=20416
1394
1395 - reading a CYMK TIFF would result in a 4 channel image, reading any
1396 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1397 result in an error.
1398 http://rt.cpan.org/Ticket/Display.html?id=20415
1399
1400 - added /usr/local/include to the default include search path, since
1401 we were already searching /usr/local/lib for libraries.
1402
1403And various minor fixes and documentation updates.
