20 - the log() method used its message parameter as a C level format
21 string.

TC
27 - add extra ppport.h configuration to support older perls.
28
954ac5d1
TC
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.

6d5c85a2 54==============
a7e32beb
TC
55
56 - add simple tests for the Imager::Test test_image generators
57
6d5c85a2
TC
58 - io_glue I/O buffering re-work:
59
60 - reorganize io_glue to do it's own buffering by default
61
62 - the unbuffered functions are available as i_io_raw_read() (or
63 raw_read() from perl) etc but are not recommended for typical
64 use.
65
66 - use the new i_io_peekn() when checking for file magic to avoid
67 seek, allowing Imager to detect the file type and read the file
68 from an unseekable stream (for formats that don't use random
69 access)
70
71 - added several new I/O layer API functions.
72
73 - fix the TGA performance problem, most noticably on Win32
74 https://rt.cpan.org/Ticket/Display.html?id=70037
75
76 - TIFF now uses wrapper functions of the correct types to avoid casts
77 https://rt.cpan.org/Ticket/Display.html?id=69912
78
79 - the callback IO object did its own buffering, controlled by the
80 maxbuffer parameter supplied to the read() and write() methods.
81 This buffering has been removed, to avoid redundancy with the
82 common io_glue buffering. This also avoids a bug in that code
83 which could rarely pass a zero length to the read callback and
84 then panic about the result.
85
86 - the callback IO object now tests the result of calling the close
87 callback, which should return true for success.
88
89 - the PNM reader did its own buffering. This buffering has been
90 removed to avoid redundancy with the common io_glue buffering.
91
92 - previously the read handlers for fd and callback I/O layers would
93 call the underlying interface (POSIX read or your supplied callback)
94 until it filled the buffer. It now only makes one call.
95
96 - added public constructors for I/O layer objects (see Imager::IO)
97
98 - all core file handlers now use the i_io_foo() wrappers to gain
99 access to buffered I/O rather than calling the I/O layer
100 callbacks directly.
101
102 - all core file handlers now check for error on close.
103
104 - Backward compatibility: if you hava custom file handlers, you can
105 use i_io_write() etc since they're available as macros in older
106 versions of Imager.
107
108 - eliminate the final remnants of io_glue_commit_types().
109
110 - bump IMAGER_API_VERSION, since the above may break assumptions.
111
112 - removed the long unused i_gen_reader() and i_gen_writer() utility
113 functions.

TC
116===========
117
0c647c9a
TC
118The main changes in the release versus 0.84 are:
119
120 - on 64-bit systems, 64-bit types are consistently used for image
121 dimensions and co-ordinated, and for memory block sizes.
122
123 - handle IFD loops in TIFF files correctly. Previously this would
124 lead to an infinite loop.
125
6ad7e4bc
TC
126Bug fixes:
127
128 - fix the link in the getheight() entry in the method index

134favourable.
6b7197d0
TC
135
136Bug fixes:
137
138 - the image file limits set by set_file_limits() weren't being
139 checked when reading TIFF files.
140 https://rt.cpan.org/Ticket/Display.html?id=69915
141
5970bd39
TC
142 - Provide more information about file format module load errors on a
143 failed image file read() or write().
144 https://rt.cpan.org/Ticket/Display.html?id=69194
145
4ce3551c
TC
146 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
147 through TIFF images, since it checks for IFD loops.
148 https://rt.cpan.org/Ticket/Display.html?id=69914
149
a16bca6d
TC
150 - don't leak memory when out of range palette indexes are supplied to
151 setscanline().
152 https://rt.cpan.org/Ticket/Display.html?id=69242
153
154 - require a later version of CPAN::Meta to ensure JSON::PP and
155 CPAN::Meta::YAML are available.
156 https://rt.cpan.org/Ticket/Display.html?id=69008
157
ac575c5f
TC
158 - hoist the per-line calculations for the flines implementations, and
159 modernize the tests a bit.
160 https://rt.cpan.org/Ticket/Display.html?id=70126
161
86c8d19a
TC
162 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
163 them when available.

165
a3fd7df7
TC
166 - if t1lib failed to reinitialize it would be left as marked

173Imager 0.84_01 - 8 Aug 2011
174==============
175
176Development release as a sanity check for the types re-work.
8d14daab
TC
177
178Massive types re-work:
179
180 - the type used internally for pixel co-ordinates and image sizes is
181 now 64-bit on 64-bit platforms (at least sane ones).
182
183 - size_t is now used consistently for memory block sizes.
184
185 - since this changes the binary interface, the Imager API version has
186 been incremented. Any module that uses the API will need to be
187 rebuilt. In most cases that will be enough, but calls to any APIs
188 that take a pointer to image sizes may need source changes.
189
190 - you should be able to create very large images on 64-bit systems,
191 if you have enough memory. Successfully created a 32768 x 49192 x
192 3 channel image, filled with a tiled image and scaled it. The
193 unscaled image was also successfully saved to a JPEG.
194
195 - check the image size before attempting to write BMP, GIF, JPEG,
196 PNG, SGI, TGA, TIFF images.
197
198 - correctly handle reading TGA images over 32767 pixels wide or tall.
199
200Incidental changes:
201
202 - the gif_left and gif_top tags are now clamped to non-negative
203 values when writing a GIF image.
204
205 - removed dead callback read/write code
206
207The default maximum memory size when reading files is now 1G.

TC
210===========
211
212 - Imager no longer inherits from Exporter (unless you're running an
213 old, old perl.
214
92e9df65
TC
215 - Imager can now write progressive JPEGs (it could always read them).

TC
218Bug fixes:

TC
234 - convert colors to grayscale if the supplied (or generated) palette
235 contains only grays when performing error diffusion color
236 translation.
237 https://rt.cpan.org/Ticket/Display.html?id=68508
238
59c150a4
TC
239 - writing a paletted image to GIF wouldn't always use the colors
240 supplied (or generated, eg. via make_colors => "mono"), which was
241 confusing at best.
242 https://rt.cpan.org/Ticket/Display.html?id=67912
243
5b480b14
TC
244 - replace (imager|tony)@imager.perl.org in the doc, since I don't

265 Win32. Thanks to kmx for the report and fix.
266 https://rt.cpan.org/Ticket/Display.html?id=67963
267
618a3282
TC
268 - compose() with the target, source or mask position off the top or
269 left of the target image didn't clip the source image correctly.
270 https://rt.cpan.org/Ticket/Display.html?id=67220
271
272 - compose() now returns a useful error message on a non-positive
273 opacity.
274
275 - compose.im now at 100% test coverage. (As opposed to, umm, much,
276 much less.)

TC
279===========
280
281Bug fixes:
282
283 - eliminate calls to i_has_format() from the test suite, since it's
284 no longer a useful way to check for file format support. Eliminate
285 i_has_format() from the functions exposed via XS.
286 https://rt.cpan.org/Ticket/Display.html?id=65863
287
7540f84a
TC
288 - eliminate calls to note(), which isn't in the (very old) version of
289 Test::More we have as a pre-requisite. note() is modern enough
290 that I don't feel a need to require a Test::More upgrade for it.
291 https://rt.cpan.org/Ticket/Display.html?id=65864
292
81984f30

303 downgrade the version in this file.
304 https://rt.cpan.org/Ticket/Display.html?id=66250
305
306 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
307 that option for the directories that would normally go in
308 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

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

857 noalpha channels or back.
858 https://rt.cpan.org/Ticket/Display.html?id=30908
859
860 - rubthrough() now falls back to pasting when the source doesn't have
861 an alpha channel. This effectively treats the source as having a
862 max alpha channel, the right thing to do.

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

915 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
916 I'll match it's behaviour. See issue 114913 in the GIMP's

927 - the old dynaload code used Mach API functions to load dynamic
928 libraries on Mac OS X. These APIs have been deprecated in OS X
929 10.5 and were causing some build problems.
930 So henceforth Imager uses the dlopen() family of functions, and you
931 will need version 10.3 or later of OS X.

1236===========

1238This is primarily a bug fix release.
1239
1240Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1241
1242There is one new feature:
1243
1244 - the Win32 font driver now supports UTF8 (RT 22166)
1245 http://www.cpanforum.com/threads/3276
1246 http://rt.cpan.org/Ticket/Display.html?id=22166
1247
1248Several bugs were fixed:
1249
1250 - the string() method would not output the string "0"
1251 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1252
1253 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1254 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1255
1256 - the gif_disposal and gif_user_input tags weren't being read from
1257 the file correctly
1258 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1259
1260 - gif.c was failing to build under MSVC
1261 http://rt.cpan.org/Ticket/Display.html?id=23922
1262
1263 - in some cases strings passed to the string() method were treated as
1264 terminated by NUL (chr 0)
1265 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1266
1267 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1268 that's the default build name for zlib on Win32.
1269 http://rt.cpan.org/Ticket/Display.html?id=23064
1270
1271 - search $Config{incpath} for headers too, which we should have been
1272 doing all along.
1273
1274Win32 font driver fixes:
1275
1276 - the global descent value from bounding box was the wrong sign
1277 http://www.cpanforum.com/threads/3276
1278
1279 - if the first or last glyph overflowed the left or right side of the
1280 advance width they would be clipped

1282
1283Imager 0.54 - 14 Sep 2006
1284===========
1285
1286This is primarily a feature release:
1287
1288 - a new qtype value 'mixing' has been added to the scale()
1289 method. This is faster than 'normal', slower than 'preview'. This
1290 is based on the method used by pnmscale, and seems to produce less
1291 blurry results than normal.
1292 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1293
1294 - the rubthrough() method can now render onto images with an alpha
1295 channel.
1296 http://rt.cpan.org/Ticket/Display.html?id=20678
1297
1298 - the read_multi() method now falls back to calling doing a single
1299 image read via the read() method and write_multi() will now fall
1300 back to calling write() if a single image is supplied. This means
1301 you can simply call the read_multi() or write_multi() functions
1302 without having to check if the type is formatted by that method.
1303 http://rt.cpan.org/Ticket/Display.html?id=19457
1304 http://rt.cpan.org/Ticket/Display.html?id=19458
1305
1306 - the GIF loop extension can now be written. If you don't have
1307 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1308 should upgrade.
1309 http://rt.cpan.org/Ticket/Display.html?id=21185
1310
1311 - getscanline() and setscanline() can now read/write palette index
1312 based data from/to the image for paletted images, by setting type to
1313 'index'.
1314 http://rt.cpan.org/Ticket/Display.html?id=20338
1315
1316 - we no longer hassle you to disable GIF support
1317 http://rt.cpan.org/Ticket/Display.html?id=20687
1318
1319 - minor documentation fixes
1320
1321
1322Imager 0.53 - 26 Jul 2006
1323===========
1324
1325This is a bugfix release.
1326
1327Some test code was left in a code path not covered by the test
1328suite. A test was added to cover this code path and the test code was
1329removed.

1334===========
1335
1336This is primarily a feature release, but contains a fair few bug
1337fixes, new features:
1338
1339 - ability to read and write MS Windows ICO and CUR files
1340
1341 - you can now add file format plugins to support new file formats
1342
1343 - add POD coverage tests
1344
1345 - setcolors() and addcolors() now accept color names and so on
1346 instead of requiring Imager::Color objects.
1347 http://rt.cpan.org/Ticket/Display.html?id=20056
1348

1354Bug fixes:
1355
1356 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1357 calculating the advance width.
1358 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1359
1360 - bounding_box for the T1 driver wasn't including leading and
1361 trailing spaces in the bounding box as the other drivers did, it also
1362 produced strange results for empty strings or strings containing only
1363 spaces
1364
1365 - when reading CMYK jpeg images they were being transferred to the
1366 image object as is, producing a four channel image. It only looked ok
1367 due to an old still unfixed Photoshop bug. We now convert from the
1368 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1369 http://rt.cpan.org/Ticket/Display.html?id=20416
1370
1371 - reading a CYMK TIFF would result in a 4 channel image, reading any
1372 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1373 result in an error.
1374 http://rt.cpan.org/Ticket/Display.html?id=20415
1375
1376 - added /usr/local/include to the default include search path, since
1377 we were already searching /usr/local/lib for libraries.
1378
1379And various minor fixes and documentation updates.
