6d5c85a2 33==============
a7e32beb
TC
34
35 - add simple tests for the Imager::Test test_image generators
36
6d5c85a2
TC
37 - io_glue I/O buffering re-work:
38
39 - reorganize io_glue to do it's own buffering by default
40
41 - the unbuffered functions are available as i_io_raw_read() (or
42 raw_read() from perl) etc but are not recommended for typical
43 use.
44
45 - use the new i_io_peekn() when checking for file magic to avoid
46 seek, allowing Imager to detect the file type and read the file
47 from an unseekable stream (for formats that don't use random
48 access)
49
50 - added several new I/O layer API functions.
51
52 - fix the TGA performance problem, most noticably on Win32
53 https://rt.cpan.org/Ticket/Display.html?id=70037
54
55 - TIFF now uses wrapper functions of the correct types to avoid casts
56 https://rt.cpan.org/Ticket/Display.html?id=69912
57
58 - the callback IO object did its own buffering, controlled by the
59 maxbuffer parameter supplied to the read() and write() methods.
60 This buffering has been removed, to avoid redundancy with the
61 common io_glue buffering. This also avoids a bug in that code
62 which could rarely pass a zero length to the read callback and
63 then panic about the result.
64
65 - the callback IO object now tests the result of calling the close
66 callback, which should return true for success.
67
68 - the PNM reader did its own buffering. This buffering has been
69 removed to avoid redundancy with the common io_glue buffering.
70
71 - previously the read handlers for fd and callback I/O layers would
72 call the underlying interface (POSIX read or your supplied callback)
73 until it filled the buffer. It now only makes one call.
74
75 - added public constructors for I/O layer objects (see Imager::IO)
76
77 - all core file handlers now use the i_io_foo() wrappers to gain
78 access to buffered I/O rather than calling the I/O layer
79 callbacks directly.
80
81 - all core file handlers now check for error on close.
82
83 - Backward compatibility: if you hava custom file handlers, you can
84 use i_io_write() etc since they're available as macros in older
85 versions of Imager.
86
87 - eliminate the final remnants of io_glue_commit_types().
88
89 - bump IMAGER_API_VERSION, since the above may break assumptions.
90
91 - removed the long unused i_gen_reader() and i_gen_writer() utility
92 functions.

TC
95===========
96
0c647c9a
TC
97The main changes in the release versus 0.84 are:
98
99 - on 64-bit systems, 64-bit types are consistently used for image
100 dimensions and co-ordinated, and for memory block sizes.
101
102 - handle IFD loops in TIFF files correctly. Previously this would
103 lead to an infinite loop.
104
6ad7e4bc
TC
105Bug fixes:

6b7197d0
TC
114
115Bug fixes:
116
117 - the image file limits set by set_file_limits() weren't being
118 checked when reading TIFF files.
119 https://rt.cpan.org/Ticket/Display.html?id=69915
120
5970bd39
TC
121 - Provide more information about file format module load errors on a
122 failed image file read() or write().
123 https://rt.cpan.org/Ticket/Display.html?id=69194
124
4ce3551c
TC
125 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
126 through TIFF images, since it checks for IFD loops.
127 https://rt.cpan.org/Ticket/Display.html?id=69914
128
a16bca6d
TC
129 - don't leak memory when out of range palette indexes are supplied to
130 setscanline().
131 https://rt.cpan.org/Ticket/Display.html?id=69242
132
133 - require a later version of CPAN::Meta to ensure JSON::PP and
134 CPAN::Meta::YAML are available.
135 https://rt.cpan.org/Ticket/Display.html?id=69008
136
ac575c5f
TC
137 - hoist the per-line calculations for the flines implementations, and
138 modernize the tests a bit.
139 https://rt.cpan.org/Ticket/Display.html?id=70126
140
86c8d19a
TC
141 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use

152Imager 0.84_01 - 8 Aug 2011
153==============
154
155Development release as a sanity check for the types re-work.
8d14daab
TC
156
157Massive types re-work:
158
159 - the type used internally for pixel co-ordinates and image sizes is
160 now 64-bit on 64-bit platforms (at least sane ones).
161
162 - size_t is now used consistently for memory block sizes.
163
164 - since this changes the binary interface, the Imager API version has
165 been incremented. Any module that uses the API will need to be
166 rebuilt. In most cases that will be enough, but calls to any APIs
167 that take a pointer to image sizes may need source changes.
168
169 - you should be able to create very large images on 64-bit systems,
170 if you have enough memory. Successfully created a 32768 x 49192 x
171 3 channel image, filled with a tiled image and scaled it. The
172 unscaled image was also successfully saved to a JPEG.
173
174 - check the image size before attempting to write BMP, GIF, JPEG,
175 PNG, SGI, TGA, TIFF images.
176
177 - correctly handle reading TGA images over 32767 pixels wide or tall.
178
179Incidental changes:
180
181 - the gif_left and gif_top tags are now clamped to non-negative
182 values when writing a GIF image.
183
184 - removed dead callback read/write code
185
186The default maximum memory size when reading files is now 1G.

TC
189===========
190
191 - Imager no longer inherits from Exporter (unless you're running an
192 old, old perl.
193
92e9df65

TC
197Bug fixes:

TC
213 - convert colors to grayscale if the supplied (or generated) palette
214 contains only grays when performing error diffusion color
215 translation.
216 https://rt.cpan.org/Ticket/Display.html?id=68508
217
59c150a4
TC
218 - writing a paletted image to GIF wouldn't always use the colors
219 supplied (or generated, eg. via make_colors => "mono"), which was
220 confusing at best.
221 https://rt.cpan.org/Ticket/Display.html?id=67912
222
5b480b14
TC
223 - replace (imager|tony)@imager.perl.org in the doc, since I don't
224 plan to continue receiving mail at that address.

245 https://rt.cpan.org/Ticket/Display.html?id=67963
246
618a3282
TC
247 - compose() with the target, source or mask position off the top or
248 left of the target image didn't clip the source image correctly.
249 https://rt.cpan.org/Ticket/Display.html?id=67220
250
251 - compose() now returns a useful error message on a non-positive
252 opacity.
253
254 - compose.im now at 100% test coverage. (As opposed to, umm, much,
255 much less.)

2368cfec
TC
258===========
259
260Bug fixes:
261
262 - eliminate calls to i_has_format() from the test suite, since it's
263 no longer a useful way to check for file format support. Eliminate
264 i_has_format() from the functions exposed via XS.
265 https://rt.cpan.org/Ticket/Display.html?id=65863
266
7540f84a
TC
267 - eliminate calls to note(), which isn't in the (very old) version of
268 Test::More we have as a pre-requisite. note() is modern enough
269 that I don't feel a need to require a Test::More upgrade for it.
270 https://rt.cpan.org/Ticket/Display.html?id=65864
271
81984f30

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

281 - increase the version of Imager::Font::Type1 so that upgrades don't
282 downgrade the version in this file.
283 https://rt.cpan.org/Ticket/Display.html?id=66250
284
285 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
286 that option for the directories that would normally go in
287 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

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

837 https://rt.cpan.org/Ticket/Display.html?id=30908
838
839 - rubthrough() now falls back to pasting when the source doesn't have
840 an alpha channel. This effectively treats the source as having a
841 max alpha channel, the right thing to do.

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

894 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so

1214Imager 0.55 - 16 Dec 2006
1215===========
1216
1217This is primarily a bug fix release.
1218
1219Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1220
1221There is one new feature:
1222
1223 - the Win32 font driver now supports UTF8 (RT 22166)
1224 http://www.cpanforum.com/threads/3276
1225 http://rt.cpan.org/Ticket/Display.html?id=22166
1226
1227Several bugs were fixed:
1228
1229 - the string() method would not output the string "0"
1230 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1231
1232 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1233 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1234
1235 - the gif_disposal and gif_user_input tags weren't being read from
1236 the file correctly
1237 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1238
1239 - gif.c was failing to build under MSVC
1240 http://rt.cpan.org/Ticket/Display.html?id=23922
1241
1242 - in some cases strings passed to the string() method were treated as
1243 terminated by NUL (chr 0)
1244 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1245
1246 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1247 that's the default build name for zlib on Win32.
1248 http://rt.cpan.org/Ticket/Display.html?id=23064
1249
1250 - search $Config{incpath} for headers too, which we should have been
1251 doing all along.
1252
1253Win32 font driver fixes:
1254
1255 - the global descent value from bounding box was the wrong sign
1256 http://www.cpanforum.com/threads/3276
1257
1258 - if the first or last glyph overflowed the left or right side of the
1259 advance width they would be clipped
1260
1261
1262Imager 0.54 - 14 Sep 2006
1263===========
1264
1265This is primarily a feature release:
1266
1267 - a new qtype value 'mixing' has been added to the scale()
1268 method. This is faster than 'normal', slower than 'preview'. This
1269 is based on the method used by pnmscale, and seems to produce less
1270 blurry results than normal.
1271 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1272
1273 - the rubthrough() method can now render onto images with an alpha
1274 channel.
1275 http://rt.cpan.org/Ticket/Display.html?id=20678
1276
1277 - the read_multi() method now falls back to calling doing a single
1278 image read via the read() method and write_multi() will now fall
1279 back to calling write() if a single image is supplied. This means
1280 you can simply call the read_multi() or write_multi() functions
1281 without having to check if the type is formatted by that method.
1282 http://rt.cpan.org/Ticket/Display.html?id=19457
1283 http://rt.cpan.org/Ticket/Display.html?id=19458
1284
1285 - the GIF loop extension can now be written. If you don't have
1286 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1287 should upgrade.
1288 http://rt.cpan.org/Ticket/Display.html?id=21185
1289
1290 - getscanline() and setscanline() can now read/write palette index
1291 based data from/to the image for paletted images, by setting type to
1292 'index'.
1293 http://rt.cpan.org/Ticket/Display.html?id=20338
1294
1295 - we no longer hassle you to disable GIF support
1296 http://rt.cpan.org/Ticket/Display.html?id=20687
1297
1298 - minor documentation fixes
1299
1300
1301Imager 0.53 - 26 Jul 2006
1302===========
1303
1304This is a bugfix release.
1305
1306Some test code was left in a code path not covered by the test
1307suite. A test was added to cover this code path and the test code was
1308removed.

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