6d5c85a2 25==============
a7e32beb
TC
26
27 - add simple tests for the Imager::Test test_image generators
28
6d5c85a2
TC
29 - io_glue I/O buffering re-work:
30
31 - reorganize io_glue to do it's own buffering by default
32
33 - the unbuffered functions are available as i_io_raw_read() (or
34 raw_read() from perl) etc but are not recommended for typical
35 use.
36
37 - use the new i_io_peekn() when checking for file magic to avoid
38 seek, allowing Imager to detect the file type and read the file
39 from an unseekable stream (for formats that don't use random
40 access)
41
42 - added several new I/O layer API functions.
43
44 - fix the TGA performance problem, most noticably on Win32
45 https://rt.cpan.org/Ticket/Display.html?id=70037
46
47 - TIFF now uses wrapper functions of the correct types to avoid casts
48 https://rt.cpan.org/Ticket/Display.html?id=69912
49
50 - the callback IO object did its own buffering, controlled by the
51 maxbuffer parameter supplied to the read() and write() methods.
52 This buffering has been removed, to avoid redundancy with the
53 common io_glue buffering. This also avoids a bug in that code
54 which could rarely pass a zero length to the read callback and
55 then panic about the result.
56
57 - the callback IO object now tests the result of calling the close
58 callback, which should return true for success.
59
60 - the PNM reader did its own buffering. This buffering has been
61 removed to avoid redundancy with the common io_glue buffering.
62
63 - previously the read handlers for fd and callback I/O layers would
64 call the underlying interface (POSIX read or your supplied callback)
65 until it filled the buffer. It now only makes one call.
66
67 - added public constructors for I/O layer objects (see Imager::IO)
68
69 - all core file handlers now use the i_io_foo() wrappers to gain
70 access to buffered I/O rather than calling the I/O layer
71 callbacks directly.
72
73 - all core file handlers now check for error on close.
74
75 - Backward compatibility: if you hava custom file handlers, you can
76 use i_io_write() etc since they're available as macros in older
77 versions of Imager.
78
79 - eliminate the final remnants of io_glue_commit_types().
80
81 - bump IMAGER_API_VERSION, since the above may break assumptions.
82
83 - removed the long unused i_gen_reader() and i_gen_writer() utility
84 functions.

TC
87===========
88
0c647c9a
TC
89The main changes in the release versus 0.84 are:
90
91 - on 64-bit systems, 64-bit types are consistently used for image
92 dimensions and co-ordinated, and for memory block sizes.
93
94 - handle IFD loops in TIFF files correctly. Previously this would
95 lead to an infinite loop.
96
6ad7e4bc

106
107Bug fixes:
108
109 - the image file limits set by set_file_limits() weren't being
110 checked when reading TIFF files.
111 https://rt.cpan.org/Ticket/Display.html?id=69915
112
5970bd39
TC
113 - Provide more information about file format module load errors on a
114 failed image file read() or write().
115 https://rt.cpan.org/Ticket/Display.html?id=69194
116
4ce3551c
TC
117 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
118 through TIFF images, since it checks for IFD loops.
119 https://rt.cpan.org/Ticket/Display.html?id=69914
120
a16bca6d
TC
121 - don't leak memory when out of range palette indexes are supplied to
122 setscanline().
123 https://rt.cpan.org/Ticket/Display.html?id=69242
124
125 - require a later version of CPAN::Meta to ensure JSON::PP and
126 CPAN::Meta::YAML are available.
127 https://rt.cpan.org/Ticket/Display.html?id=69008
128
ac575c5f
TC
129 - hoist the per-line calculations for the flines implementations, and
130 modernize the tests a bit.
131 https://rt.cpan.org/Ticket/Display.html?id=70126
132
86c8d19a
TC
133 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use

144Imager 0.84_01 - 8 Aug 2011
145==============
146
147Development release as a sanity check for the types re-work.
8d14daab
TC
148
149Massive types re-work:
150
151 - the type used internally for pixel co-ordinates and image sizes is
152 now 64-bit on 64-bit platforms (at least sane ones).
153
154 - size_t is now used consistently for memory block sizes.
155
156 - since this changes the binary interface, the Imager API version has
157 been incremented. Any module that uses the API will need to be
158 rebuilt. In most cases that will be enough, but calls to any APIs
159 that take a pointer to image sizes may need source changes.
160
161 - you should be able to create very large images on 64-bit systems,
162 if you have enough memory. Successfully created a 32768 x 49192 x
163 3 channel image, filled with a tiled image and scaled it. The
164 unscaled image was also successfully saved to a JPEG.
165
166 - check the image size before attempting to write BMP, GIF, JPEG,
167 PNG, SGI, TGA, TIFF images.
168
169 - correctly handle reading TGA images over 32767 pixels wide or tall.
170
171Incidental changes:
172
173 - the gif_left and gif_top tags are now clamped to non-negative
174 values when writing a GIF image.
175
176 - removed dead callback read/write code
177
178The default maximum memory size when reading files is now 1G.

181===========
182

184 old, old perl.
185

TC
205 - convert colors to grayscale if the supplied (or generated) palette
206 contains only grays when performing error diffusion color
207 translation.
208 https://rt.cpan.org/Ticket/Display.html?id=68508
209
59c150a4
TC
210 - writing a paletted image to GIF wouldn't always use the colors
211 supplied (or generated, eg. via make_colors => "mono"), which was
212 confusing at best.
213 https://rt.cpan.org/Ticket/Display.html?id=67912
214
5b480b14
TC
215 - replace (imager|tony)@imager.perl.org in the doc, since I don't

239 - compose() with the target, source or mask position off the top or
240 left of the target image didn't clip the source image correctly.
241 https://rt.cpan.org/Ticket/Display.html?id=67220
242
243 - compose() now returns a useful error message on a non-positive
244 opacity.
245
246 - compose.im now at 100% test coverage. (As opposed to, umm, much,
247 much less.)

TC
250===========
251
252Bug fixes:
253
254 - eliminate calls to i_has_format() from the test suite, since it's
255 no longer a useful way to check for file format support. Eliminate
256 i_has_format() from the functions exposed via XS.
257 https://rt.cpan.org/Ticket/Display.html?id=65863
258
7540f84a
TC
259 - eliminate calls to note(), which isn't in the (very old) version of
260 Test::More we have as a pre-requisite. note() is modern enough
261 that I don't feel a need to require a Test::More upgrade for it.
262 https://rt.cpan.org/Ticket/Display.html?id=65864
263
81984f30

273 - increase the version of Imager::Font::Type1 so that upgrades don't
274 downgrade the version in this file.
275 https://rt.cpan.org/Ticket/Display.html?id=66250
276
277 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
278 that option for the directories that would normally go in
279 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

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

446 used for color translation on Unix-like systems, and the fix
447 improves performance of supplying colors by name by about 80 times.

831 - rubthrough() now falls back to pasting when the source doesn't have
832 an alpha channel. This effectively treats the source as having a
833 max alpha channel, the right thing to do.

1207===========
1208
1209This is primarily a bug fix release.
1210
1211Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1212
1213There is one new feature:
1214
1215 - the Win32 font driver now supports UTF8 (RT 22166)
1216 http://www.cpanforum.com/threads/3276
1217 http://rt.cpan.org/Ticket/Display.html?id=22166
1218
1219Several bugs were fixed:
1220
1221 - the string() method would not output the string "0"
1222 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1223
1224 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1225 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1226
1227 - the gif_disposal and gif_user_input tags weren't being read from
1228 the file correctly
1229 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1230
1231 - gif.c was failing to build under MSVC
1232 http://rt.cpan.org/Ticket/Display.html?id=23922
1233
1234 - in some cases strings passed to the string() method were treated as
1235 terminated by NUL (chr 0)
1236 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1237
1238 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1239 that's the default build name for zlib on Win32.
1240 http://rt.cpan.org/Ticket/Display.html?id=23064
1241
1242 - search $Config{incpath} for headers too, which we should have been
1243 doing all along.
1244
1245Win32 font driver fixes:
1246
1247 - the global descent value from bounding box was the wrong sign
1248 http://www.cpanforum.com/threads/3276
1249
1250 - if the first or last glyph overflowed the left or right side of the
1251 advance width they would be clipped
1252
1253
1254Imager 0.54 - 14 Sep 2006
1255===========
1256
1257This is primarily a feature release:
1258
1259 - a new qtype value 'mixing' has been added to the scale()
1260 method. This is faster than 'normal', slower than 'preview'. This
1261 is based on the method used by pnmscale, and seems to produce less
1262 blurry results than normal.
1263 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1264
1265 - the rubthrough() method can now render onto images with an alpha
1266 channel.
1267 http://rt.cpan.org/Ticket/Display.html?id=20678
1268
1269 - the read_multi() method now falls back to calling doing a single
1270 image read via the read() method and write_multi() will now fall
1271 back to calling write() if a single image is supplied. This means
1272 you can simply call the read_multi() or write_multi() functions
1273 without having to check if the type is formatted by that method.
1274 http://rt.cpan.org/Ticket/Display.html?id=19457
1275 http://rt.cpan.org/Ticket/Display.html?id=19458
1276
1277 - the GIF loop extension can now be written. If you don't have
1278 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1279 should upgrade.
1280 http://rt.cpan.org/Ticket/Display.html?id=21185
1281
1282 - getscanline() and setscanline() can now read/write palette index
1283 based data from/to the image for paletted images, by setting type to
1284 'index'.
1285 http://rt.cpan.org/Ticket/Display.html?id=20338
1286
1287 - we no longer hassle you to disable GIF support
1288 http://rt.cpan.org/Ticket/Display.html?id=20687
1289
1290 - minor documentation fixes
1291
1292
1293Imager 0.53 - 26 Jul 2006
1294===========
1295
1296This is a bugfix release.
1297
1298Some test code was left in a code path not covered by the test
1299suite. A test was added to cover this code path and the test code was
1300removed.

1304Imager 0.52 - 25 Jul 2006
1305===========
1306
1307This is primarily a feature release, but contains a fair few bug
1308fixes, new features:
1309
1310 - ability to read and write MS Windows ICO and CUR files
1311
1312 - you can now add file format plugins to support new file formats
1313
1314 - add POD coverage tests
1315
1316 - setcolors() and addcolors() now accept color names and so on
1317 instead of requiring Imager::Color objects.
1318 http://rt.cpan.org/Ticket/Display.html?id=20056
1319
1320 - flood_fill() can now fill to a specified border color instead of
1321 just to the area the same color as the seed.
1322 http://rt.cpan.org/Ticket/Display.html?id=19618
1323
1324
1325Bug fixes:
1326
1327 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1328 calculating the advance width.
1329 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1330
1331 - bounding_box for the T1 driver wasn't including leading and
1332 trailing spaces in the bounding box as the other drivers did, it also
1333 produced strange results for empty strings or strings containing only
1334 spaces
1335
1336 - when reading CMYK jpeg images they were being transferred to the
1337 image object as is, producing a four channel image. It only looked ok
1338 due to an old still unfixed Photoshop bug. We now convert from the
1339 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1340 http://rt.cpan.org/Ticket/Display.html?id=20416
1341
1342 - reading a CYMK TIFF would result in a 4 channel image, reading any
1343 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1344 result in an error.
1345 http://rt.cpan.org/Ticket/Display.html?id=20415
1346
1347 - added /usr/local/include to the default include search path, since
1348 we were already searching /usr/local/lib for libraries.
1349
1350And various minor fixes and documentation updates.
1351
1352
1353Imager 0.51 - 23 Apr 2006
1354===========
1355
