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

6d5c85a2 50==============
a7e32beb
TC
51
52 - add simple tests for the Imager::Test test_image generators
53
6d5c85a2
TC
54 - io_glue I/O buffering re-work:
55
56 - reorganize io_glue to do it's own buffering by default
57
58 - the unbuffered functions are available as i_io_raw_read() (or
59 raw_read() from perl) etc but are not recommended for typical
60 use.
61
62 - use the new i_io_peekn() when checking for file magic to avoid
63 seek, allowing Imager to detect the file type and read the file
64 from an unseekable stream (for formats that don't use random
65 access)
66
67 - added several new I/O layer API functions.
68
69 - fix the TGA performance problem, most noticably on Win32
70 https://rt.cpan.org/Ticket/Display.html?id=70037
71
72 - TIFF now uses wrapper functions of the correct types to avoid casts
73 https://rt.cpan.org/Ticket/Display.html?id=69912
74
75 - the callback IO object did its own buffering, controlled by the
76 maxbuffer parameter supplied to the read() and write() methods.
77 This buffering has been removed, to avoid redundancy with the
78 common io_glue buffering. This also avoids a bug in that code
79 which could rarely pass a zero length to the read callback and
80 then panic about the result.
81
82 - the callback IO object now tests the result of calling the close
83 callback, which should return true for success.
84
85 - the PNM reader did its own buffering. This buffering has been
86 removed to avoid redundancy with the common io_glue buffering.
87
88 - previously the read handlers for fd and callback I/O layers would
89 call the underlying interface (POSIX read or your supplied callback)
90 until it filled the buffer. It now only makes one call.
91
92 - added public constructors for I/O layer objects (see Imager::IO)
93
94 - all core file handlers now use the i_io_foo() wrappers to gain
95 access to buffered I/O rather than calling the I/O layer
96 callbacks directly.
97
98 - all core file handlers now check for error on close.
99
100 - Backward compatibility: if you hava custom file handlers, you can
101 use i_io_write() etc since they're available as macros in older
102 versions of Imager.
103
104 - eliminate the final remnants of io_glue_commit_types().
105
106 - bump IMAGER_API_VERSION, since the above may break assumptions.
107
108 - removed the long unused i_gen_reader() and i_gen_writer() utility
109 functions.

6ad7e4bc
TC
112===========
113
0c647c9a
TC
114The main changes in the release versus 0.84 are:
115
116 - on 64-bit systems, 64-bit types are consistently used for image
117 dimensions and co-ordinated, and for memory block sizes.
118
119 - handle IFD loops in TIFF files correctly. Previously this would
120 lead to an infinite loop.
121
6ad7e4bc
TC
122Bug fixes:
123
124 - fix the link in the getheight() entry in the method index

6b7197d0
TC
131
132Bug fixes:
133
134 - the image file limits set by set_file_limits() weren't being
135 checked when reading TIFF files.
136 https://rt.cpan.org/Ticket/Display.html?id=69915
137
5970bd39
TC
138 - Provide more information about file format module load errors on a
139 failed image file read() or write().
140 https://rt.cpan.org/Ticket/Display.html?id=69194
141
4ce3551c
TC
142 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
143 through TIFF images, since it checks for IFD loops.
144 https://rt.cpan.org/Ticket/Display.html?id=69914
145
a16bca6d
TC
146 - don't leak memory when out of range palette indexes are supplied to
147 setscanline().
148 https://rt.cpan.org/Ticket/Display.html?id=69242
149
150 - require a later version of CPAN::Meta to ensure JSON::PP and
151 CPAN::Meta::YAML are available.
152 https://rt.cpan.org/Ticket/Display.html?id=69008
153
ac575c5f
TC
154 - hoist the per-line calculations for the flines implementations, and
155 modernize the tests a bit.
156 https://rt.cpan.org/Ticket/Display.html?id=70126
157
86c8d19a
TC
158 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
159 them when available.

161
a3fd7df7

169Imager 0.84_01 - 8 Aug 2011
170==============
171
172Development release as a sanity check for the types re-work.
8d14daab
TC
173
174Massive types re-work:
175
176 - the type used internally for pixel co-ordinates and image sizes is
177 now 64-bit on 64-bit platforms (at least sane ones).
178
179 - size_t is now used consistently for memory block sizes.
180
181 - since this changes the binary interface, the Imager API version has
182 been incremented. Any module that uses the API will need to be
183 rebuilt. In most cases that will be enough, but calls to any APIs
184 that take a pointer to image sizes may need source changes.
185
186 - you should be able to create very large images on 64-bit systems,
187 if you have enough memory. Successfully created a 32768 x 49192 x
188 3 channel image, filled with a tiled image and scaled it. The
189 unscaled image was also successfully saved to a JPEG.
190
191 - check the image size before attempting to write BMP, GIF, JPEG,
192 PNG, SGI, TGA, TIFF images.
193
194 - correctly handle reading TGA images over 32767 pixels wide or tall.
195
196Incidental changes:
197
198 - the gif_left and gif_top tags are now clamped to non-negative
199 values when writing a GIF image.
200
201 - removed dead callback read/write code
202
203The default maximum memory size when reading files is now 1G.

b1e66a82
TC
206===========
207
208 - Imager no longer inherits from Exporter (unless you're running an
209 old, old perl.
210
92e9df65
TC
211 - Imager can now write progressive JPEGs (it could always read them).

229
6d068d36
TC
230 - convert colors to grayscale if the supplied (or generated) palette
231 contains only grays when performing error diffusion color
232 translation.
233 https://rt.cpan.org/Ticket/Display.html?id=68508
234
59c150a4
TC
235 - writing a paletted image to GIF wouldn't always use the colors
236 supplied (or generated, eg. via make_colors => "mono"), which was
237 confusing at best.
238 https://rt.cpan.org/Ticket/Display.html?id=67912
239
5b480b14
TC
240 - replace (imager|tony)@imager.perl.org in the doc, since I don't

262 https://rt.cpan.org/Ticket/Display.html?id=67963
263
618a3282
TC
264 - compose() with the target, source or mask position off the top or
265 left of the target image didn't clip the source image correctly.
266 https://rt.cpan.org/Ticket/Display.html?id=67220
267
268 - compose() now returns a useful error message on a non-positive
269 opacity.
270
271 - compose.im now at 100% test coverage. (As opposed to, umm, much,
272 much less.)

2368cfec
TC
275===========
276
277Bug fixes:
278
279 - eliminate calls to i_has_format() from the test suite, since it's
280 no longer a useful way to check for file format support. Eliminate
281 i_has_format() from the functions exposed via XS.
282 https://rt.cpan.org/Ticket/Display.html?id=65863
283
7540f84a
TC
284 - eliminate calls to note(), which isn't in the (very old) version of
285 Test::More we have as a pre-requisite. note() is modern enough
286 that I don't feel a need to require a Test::More upgrade for it.
287 https://rt.cpan.org/Ticket/Display.html?id=65864
288
81984f30

289 - skip the threads tests on Test::More 2.00_*

299 downgrade the version in this file.
300 https://rt.cpan.org/Ticket/Display.html?id=66250
301
302 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
303 that option for the directories that would normally go in
304 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

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

854 https://rt.cpan.org/Ticket/Display.html?id=30908
855
856 - rubthrough() now falls back to pasting when the source doesn't have
857 an alpha channel. This effectively treats the source as having a
858 max alpha channel, the right thing to do.

923 - the old dynaload code used Mach API functions to load dynamic
924 libraries on Mac OS X. These APIs have been deprecated in OS X
925 10.5 and were causing some build problems.
926 So henceforth Imager uses the dlopen() family of functions, and you
927 will need version 10.3 or later of OS X.

1231Imager 0.55 - 16 Dec 2006
1232===========
1233
1234This is primarily a bug fix release.
1235
1236Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1237
1238There is one new feature:
1239
1240 - the Win32 font driver now supports UTF8 (RT 22166)
1241 http://www.cpanforum.com/threads/3276
1242 http://rt.cpan.org/Ticket/Display.html?id=22166
1243
1244Several bugs were fixed:
1245
1246 - the string() method would not output the string "0"
1247 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1248
1249 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1250 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1251
1252 - the gif_disposal and gif_user_input tags weren't being read from
1253 the file correctly
1254 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1255
1256 - gif.c was failing to build under MSVC
1257 http://rt.cpan.org/Ticket/Display.html?id=23922
1258
1259 - in some cases strings passed to the string() method were treated as
1260 terminated by NUL (chr 0)
1261 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1262
1263 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1264 that's the default build name for zlib on Win32.
1265 http://rt.cpan.org/Ticket/Display.html?id=23064
1266
1267 - search $Config{incpath} for headers too, which we should have been
1268 doing all along.
1269
1270Win32 font driver fixes:
1271
1272 - the global descent value from bounding box was the wrong sign
1273 http://www.cpanforum.com/threads/3276
1274
1275 - if the first or last glyph overflowed the left or right side of the
1276 advance width they would be clipped

1278
1279Imager 0.54 - 14 Sep 2006
1280===========
1281
1282This is primarily a feature release:
1283
1284 - a new qtype value 'mixing' has been added to the scale()
1285 method. This is faster than 'normal', slower than 'preview'. This
1286 is based on the method used by pnmscale, and seems to produce less
1287 blurry results than normal.
1288 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1289
1290 - the rubthrough() method can now render onto images with an alpha
1291 channel.
1292 http://rt.cpan.org/Ticket/Display.html?id=20678
1293
1294 - the read_multi() method now falls back to calling doing a single
1295 image read via the read() method and write_multi() will now fall
1296 back to calling write() if a single image is supplied. This means
1297 you can simply call the read_multi() or write_multi() functions
1298 without having to check if the type is formatted by that method.
1299 http://rt.cpan.org/Ticket/Display.html?id=19457
1300 http://rt.cpan.org/Ticket/Display.html?id=19458
1301
1302 - the GIF loop extension can now be written. If you don't have
1303 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1304 should upgrade.
1305 http://rt.cpan.org/Ticket/Display.html?id=21185
1306
1307 - getscanline() and setscanline() can now read/write palette index
1308 based data from/to the image for paletted images, by setting type to
1309 'index'.
1310 http://rt.cpan.org/Ticket/Display.html?id=20338
1311
1312 - we no longer hassle you to disable GIF support
1313 http://rt.cpan.org/Ticket/Display.html?id=20687
1314
1315 - minor documentation fixes
1316
1317
1318Imager 0.53 - 26 Jul 2006
1319===========
1320
1321This is a bugfix release.
1322
1323Some test code was left in a code path not covered by the test
1324suite. A test was added to cover this code path and the test code was
1325removed.

1334
1335 - ability to read and write MS Windows ICO and CUR files
1336
1337 - you can now add file format plugins to support new file formats
1338
1339 - add POD coverage tests
1340
1341 - setcolors() and addcolors() now accept color names and so on
1342 instead of requiring Imager::Color objects.
1343 http://rt.cpan.org/Ticket/Display.html?id=20056
1344
1345 - flood_fill() can now fill to a specified border color instead of
1346 just to the area the same color as the seed.
1347 http://rt.cpan.org/Ticket/Display.html?id=19618
1348
1349
1350Bug fixes:
1351
1352 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1353 calculating the advance width.

1355
1356 - bounding_box for the T1 driver wasn't including leading and
1357 trailing spaces in the bounding box as the other drivers did, it also
1358 produced strange results for empty strings or strings containing only
1359 spaces

1361 - when reading CMYK jpeg images they were being transferred to the
1362 image object as is, producing a four channel image. It only looked ok
1363 due to an old still unfixed Photoshop bug. We now convert from the
1364 inverted CMYK that photoshop (and Corel for example) produce into RGB.

1367 - reading a CYMK TIFF would result in a 4 channel image, reading any
1368 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1369 result in an error.

1372 - added /usr/local/include to the default include search path, since
1373 we were already searching /usr/local/lib for libraries.
