6d5c85a2 28==============
a7e32beb
TC
29
30 - add simple tests for the Imager::Test test_image generators
31
6d5c85a2
TC
32 - io_glue I/O buffering re-work:
33
34 - reorganize io_glue to do it's own buffering by default
35
36 - the unbuffered functions are available as i_io_raw_read() (or
37 raw_read() from perl) etc but are not recommended for typical
38 use.
39
40 - use the new i_io_peekn() when checking for file magic to avoid
41 seek, allowing Imager to detect the file type and read the file
42 from an unseekable stream (for formats that don't use random
43 access)
44
45 - added several new I/O layer API functions.
46
47 - fix the TGA performance problem, most noticably on Win32
48 https://rt.cpan.org/Ticket/Display.html?id=70037
49
50 - TIFF now uses wrapper functions of the correct types to avoid casts
51 https://rt.cpan.org/Ticket/Display.html?id=69912
52
53 - the callback IO object did its own buffering, controlled by the
54 maxbuffer parameter supplied to the read() and write() methods.
55 This buffering has been removed, to avoid redundancy with the
56 common io_glue buffering. This also avoids a bug in that code
57 which could rarely pass a zero length to the read callback and
58 then panic about the result.
59
60 - the callback IO object now tests the result of calling the close
61 callback, which should return true for success.
62
63 - the PNM reader did its own buffering. This buffering has been
64 removed to avoid redundancy with the common io_glue buffering.
65
66 - previously the read handlers for fd and callback I/O layers would
67 call the underlying interface (POSIX read or your supplied callback)
68 until it filled the buffer. It now only makes one call.
69
70 - added public constructors for I/O layer objects (see Imager::IO)
71
72 - all core file handlers now use the i_io_foo() wrappers to gain
73 access to buffered I/O rather than calling the I/O layer
74 callbacks directly.
75
76 - all core file handlers now check for error on close.
77
78 - Backward compatibility: if you hava custom file handlers, you can
79 use i_io_write() etc since they're available as macros in older
80 versions of Imager.
81
82 - eliminate the final remnants of io_glue_commit_types().
83
84 - bump IMAGER_API_VERSION, since the above may break assumptions.
85
86 - removed the long unused i_gen_reader() and i_gen_writer() utility
87 functions.

TC
90===========
91
0c647c9a
TC
92The main changes in the release versus 0.84 are:
93
94 - on 64-bit systems, 64-bit types are consistently used for image
95 dimensions and co-ordinated, and for memory block sizes.
96
97 - handle IFD loops in TIFF files correctly. Previously this would
98 lead to an infinite loop.
99

108favourable.
6b7197d0
TC
109
110Bug fixes:
111
112 - the image file limits set by set_file_limits() weren't being
113 checked when reading TIFF files.
114 https://rt.cpan.org/Ticket/Display.html?id=69915
115
5970bd39
TC
116 - Provide more information about file format module load errors on a
117 failed image file read() or write().
118 https://rt.cpan.org/Ticket/Display.html?id=69194
119
4ce3551c
TC
120 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
121 through TIFF images, since it checks for IFD loops.
122 https://rt.cpan.org/Ticket/Display.html?id=69914
123
a16bca6d
TC
124 - don't leak memory when out of range palette indexes are supplied to
125 setscanline().
126 https://rt.cpan.org/Ticket/Display.html?id=69242
127
128 - require a later version of CPAN::Meta to ensure JSON::PP and
129 CPAN::Meta::YAML are available.
130 https://rt.cpan.org/Ticket/Display.html?id=69008
131
ac575c5f
TC
132 - hoist the per-line calculations for the flines implementations, and
133 modernize the tests a bit.
134 https://rt.cpan.org/Ticket/Display.html?id=70126
135
86c8d19a
TC
136 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
137 them when available.

147Imager 0.84_01 - 8 Aug 2011
148==============
149
150Development release as a sanity check for the types re-work.
8d14daab
TC
151
152Massive types re-work:
153
154 - the type used internally for pixel co-ordinates and image sizes is
155 now 64-bit on 64-bit platforms (at least sane ones).
156
157 - size_t is now used consistently for memory block sizes.
158
159 - since this changes the binary interface, the Imager API version has
160 been incremented. Any module that uses the API will need to be
161 rebuilt. In most cases that will be enough, but calls to any APIs
162 that take a pointer to image sizes may need source changes.
163
164 - you should be able to create very large images on 64-bit systems,
165 if you have enough memory. Successfully created a 32768 x 49192 x
166 3 channel image, filled with a tiled image and scaled it. The
167 unscaled image was also successfully saved to a JPEG.
168
169 - check the image size before attempting to write BMP, GIF, JPEG,
170 PNG, SGI, TGA, TIFF images.
171
172 - correctly handle reading TGA images over 32767 pixels wide or tall.
173
174Incidental changes:
175
176 - the gif_left and gif_top tags are now clamped to non-negative
177 values when writing a GIF image.
178
179 - removed dead callback read/write code
180
181The default maximum memory size when reading files is now 1G.

b1e66a82
TC
184===========
185
186 - Imager no longer inherits from Exporter (unless you're running an
187 old, old perl.
188
92e9df65
TC
189 - Imager can now write progressive JPEGs (it could always read them).

TC
192Bug fixes:

TC
208 - convert colors to grayscale if the supplied (or generated) palette
209 contains only grays when performing error diffusion color
210 translation.
211 https://rt.cpan.org/Ticket/Display.html?id=68508
212
59c150a4
TC
213 - writing a paletted image to GIF wouldn't always use the colors
214 supplied (or generated, eg. via make_colors => "mono"), which was
215 confusing at best.
216 https://rt.cpan.org/Ticket/Display.html?id=67912
217
5b480b14
TC
218 - replace (imager|tony)@imager.perl.org in the doc, since I don't
219 plan to continue receiving mail at that address.

234Dev release, in case the compose tests are too sensitive.
deb1a916
TC
235
236Bug fixes:
237
238 - Imager::Font::T1 incorrectly checked for absolute filename under
239 Win32. Thanks to kmx for the report and fix.
240 https://rt.cpan.org/Ticket/Display.html?id=67963
241
618a3282
TC
242 - compose() with the target, source or mask position off the top or
243 left of the target image didn't clip the source image correctly.
244 https://rt.cpan.org/Ticket/Display.html?id=67220
245
246 - compose() now returns a useful error message on a non-positive
247 opacity.
248
249 - compose.im now at 100% test coverage. (As opposed to, umm, much,
250 much less.)

2368cfec
TC
253===========
254
255Bug fixes:
256
257 - eliminate calls to i_has_format() from the test suite, since it's
258 no longer a useful way to check for file format support. Eliminate
259 i_has_format() from the functions exposed via XS.
260 https://rt.cpan.org/Ticket/Display.html?id=65863
261
7540f84a
TC
262 - eliminate calls to note(), which isn't in the (very old) version of
263 Test::More we have as a pre-requisite. note() is modern enough
264 that I don't feel a need to require a Test::More upgrade for it.
265 https://rt.cpan.org/Ticket/Display.html?id=65864
266
81984f30
TC
267 - skip the threads tests on Test::More 2.00_*

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

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

173c91ba 448 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
449 used for color translation on Unix-like systems, and the fix
450 improves performance of supplying colors by name by about 80 times.

832 https://rt.cpan.org/Ticket/Display.html?id=30908
833
834 - rubthrough() now falls back to pasting when the source doesn't have
835 an alpha channel. This effectively treats the source as having a
836 max alpha channel, the right thing to do.

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

1210===========
1211
1212This is primarily a bug fix release.
1213
1214Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1215
1216There is one new feature:
1217
1218 - the Win32 font driver now supports UTF8 (RT 22166)
1219 http://www.cpanforum.com/threads/3276
1220 http://rt.cpan.org/Ticket/Display.html?id=22166
1221
1222Several bugs were fixed:
1223
1224 - the string() method would not output the string "0"
1225 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1226
1227 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1228 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1229
1230 - the gif_disposal and gif_user_input tags weren't being read from
1231 the file correctly
1232 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1233
1234 - gif.c was failing to build under MSVC
1235 http://rt.cpan.org/Ticket/Display.html?id=23922
1236
1237 - in some cases strings passed to the string() method were treated as
1238 terminated by NUL (chr 0)
1239 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1240
1241 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1242 that's the default build name for zlib on Win32.
1243 http://rt.cpan.org/Ticket/Display.html?id=23064
1244
1245 - search $Config{incpath} for headers too, which we should have been
1246 doing all along.
1247
1248Win32 font driver fixes:
1249
1250 - the global descent value from bounding box was the wrong sign
1251 http://www.cpanforum.com/threads/3276
1252
1253 - if the first or last glyph overflowed the left or right side of the
1254 advance width they would be clipped
1255
1256
1257Imager 0.54 - 14 Sep 2006
1258===========
1259
1260This is primarily a feature release:
1261
1262 - a new qtype value 'mixing' has been added to the scale()
1263 method. This is faster than 'normal', slower than 'preview'. This
1264 is based on the method used by pnmscale, and seems to produce less
1265 blurry results than normal.
1266 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1267
1268 - the rubthrough() method can now render onto images with an alpha
1269 channel.
1270 http://rt.cpan.org/Ticket/Display.html?id=20678
1271
1272 - the read_multi() method now falls back to calling doing a single
1273 image read via the read() method and write_multi() will now fall
1274 back to calling write() if a single image is supplied. This means
1275 you can simply call the read_multi() or write_multi() functions
1276 without having to check if the type is formatted by that method.
1277 http://rt.cpan.org/Ticket/Display.html?id=19457
1278 http://rt.cpan.org/Ticket/Display.html?id=19458
1279
1280 - the GIF loop extension can now be written. If you don't have
1281 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1282 should upgrade.
1283 http://rt.cpan.org/Ticket/Display.html?id=21185
1284
1285 - getscanline() and setscanline() can now read/write palette index
1286 based data from/to the image for paletted images, by setting type to
1287 'index'.
1288 http://rt.cpan.org/Ticket/Display.html?id=20338
1289
1290 - we no longer hassle you to disable GIF support
1291 http://rt.cpan.org/Ticket/Display.html?id=20687
1292
1293 - minor documentation fixes
1294
1295
1296Imager 0.53 - 26 Jul 2006
1297===========
1298
1299This is a bugfix release.
1300
1301Some test code was left in a code path not covered by the test
1302suite. A test was added to cover this code path and the test code was
1303removed.

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