TC
13
14 - add simple tests for the Imager::Test test_image generators
15
6d5c85a2
TC
16 - io_glue I/O buffering re-work:
17
18 - reorganize io_glue to do it's own buffering by default
19
20 - the unbuffered functions are available as i_io_raw_read() (or
21 raw_read() from perl) etc but are not recommended for typical
22 use.
23
24 - use the new i_io_peekn() when checking for file magic to avoid
25 seek, allowing Imager to detect the file type and read the file
26 from an unseekable stream (for formats that don't use random
27 access)
28
29 - added several new I/O layer API functions.
30
31 - fix the TGA performance problem, most noticably on Win32
32 https://rt.cpan.org/Ticket/Display.html?id=70037
33
34 - TIFF now uses wrapper functions of the correct types to avoid casts
35 https://rt.cpan.org/Ticket/Display.html?id=69912
36
37 - the callback IO object did its own buffering, controlled by the
38 maxbuffer parameter supplied to the read() and write() methods.
39 This buffering has been removed, to avoid redundancy with the
40 common io_glue buffering. This also avoids a bug in that code
41 which could rarely pass a zero length to the read callback and
42 then panic about the result.
43
44 - the callback IO object now tests the result of calling the close
45 callback, which should return true for success.
46
47 - the PNM reader did its own buffering. This buffering has been
48 removed to avoid redundancy with the common io_glue buffering.
49
50 - previously the read handlers for fd and callback I/O layers would
51 call the underlying interface (POSIX read or your supplied callback)
52 until it filled the buffer. It now only makes one call.
53
54 - added public constructors for I/O layer objects (see Imager::IO)
55
56 - all core file handlers now use the i_io_foo() wrappers to gain
57 access to buffered I/O rather than calling the I/O layer
58 callbacks directly.
59
60 - all core file handlers now check for error on close.
61
62 - Backward compatibility: if you hava custom file handlers, you can
63 use i_io_write() etc since they're available as macros in older
64 versions of Imager.
65
66 - eliminate the final remnants of io_glue_commit_types().
67
68 - bump IMAGER_API_VERSION, since the above may break assumptions.
69
70 - removed the long unused i_gen_reader() and i_gen_writer() utility
71 functions.

TC
74===========
75
0c647c9a
TC
76The main changes in the release versus 0.84 are:
77
78 - on 64-bit systems, 64-bit types are consistently used for image
79 dimensions and co-ordinated, and for memory block sizes.
80
81 - handle IFD loops in TIFF files correctly. Previously this would
82 lead to an infinite loop.
83
6ad7e4bc
TC
84Bug fixes:

93
94Bug fixes:
95
96 - the image file limits set by set_file_limits() weren't being
97 checked when reading TIFF files.
98 https://rt.cpan.org/Ticket/Display.html?id=69915
99
5970bd39
TC
100 - Provide more information about file format module load errors on a
101 failed image file read() or write().
102 https://rt.cpan.org/Ticket/Display.html?id=69194
103
4ce3551c
TC
104 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
105 through TIFF images, since it checks for IFD loops.
106 https://rt.cpan.org/Ticket/Display.html?id=69914
107
a16bca6d
TC
108 - don't leak memory when out of range palette indexes are supplied to
109 setscanline().
110 https://rt.cpan.org/Ticket/Display.html?id=69242
111
112 - require a later version of CPAN::Meta to ensure JSON::PP and
113 CPAN::Meta::YAML are available.
114 https://rt.cpan.org/Ticket/Display.html?id=69008
115
ac575c5f
TC
116 - hoist the per-line calculations for the flines implementations, and
117 modernize the tests a bit.
118 https://rt.cpan.org/Ticket/Display.html?id=70126
119
86c8d19a
TC
120 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use

131Imager 0.84_01 - 8 Aug 2011
132==============
133
134Development release as a sanity check for the types re-work.
8d14daab
TC
135
136Massive types re-work:
137
138 - the type used internally for pixel co-ordinates and image sizes is
139 now 64-bit on 64-bit platforms (at least sane ones).
140
141 - size_t is now used consistently for memory block sizes.
142
143 - since this changes the binary interface, the Imager API version has
144 been incremented. Any module that uses the API will need to be
145 rebuilt. In most cases that will be enough, but calls to any APIs
146 that take a pointer to image sizes may need source changes.
147
148 - you should be able to create very large images on 64-bit systems,
149 if you have enough memory. Successfully created a 32768 x 49192 x
150 3 channel image, filled with a tiled image and scaled it. The
151 unscaled image was also successfully saved to a JPEG.
152
153 - check the image size before attempting to write BMP, GIF, JPEG,
154 PNG, SGI, TGA, TIFF images.
155
156 - correctly handle reading TGA images over 32767 pixels wide or tall.
157
158Incidental changes:
159
160 - the gif_left and gif_top tags are now clamped to non-negative
161 values when writing a GIF image.
162
163 - removed dead callback read/write code
164
165The default maximum memory size when reading files is now 1G.

TC
192 - convert colors to grayscale if the supplied (or generated) palette
193 contains only grays when performing error diffusion color
194 translation.
195 https://rt.cpan.org/Ticket/Display.html?id=68508
196
59c150a4
TC
197 - writing a paletted image to GIF wouldn't always use the colors
198 supplied (or generated, eg. via make_colors => "mono"), which was
199 confusing at best.
200 https://rt.cpan.org/Ticket/Display.html?id=67912
201
5b480b14
TC
202 - replace (imager|tony)@imager.perl.org in the doc, since I don't
203 plan to continue receiving mail at that address.

TC
219
220Bug fixes:
221
222 - Imager::Font::T1 incorrectly checked for absolute filename under
223 Win32. Thanks to kmx for the report and fix.

225

TC
226 - compose() with the target, source or mask position off the top or
227 left of the target image didn't clip the source image correctly.
228 https://rt.cpan.org/Ticket/Display.html?id=67220
229
230 - compose() now returns a useful error message on a non-positive
231 opacity.
232
233 - compose.im now at 100% test coverage. (As opposed to, umm, much,

TC
237===========
238
239Bug fixes:
240
241 - eliminate calls to i_has_format() from the test suite, since it's
242 no longer a useful way to check for file format support. Eliminate
243 i_has_format() from the functions exposed via XS.
244 https://rt.cpan.org/Ticket/Display.html?id=65863
245
7540f84a
TC
246 - eliminate calls to note(), which isn't in the (very old) version of
247 Test::More we have as a pre-requisite. note() is modern enough
248 that I don't feel a need to require a Test::More upgrade for it.
249 https://rt.cpan.org/Ticket/Display.html?id=65864
250
81984f30

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

260 - increase the version of Imager::Font::Type1 so that upgrades don't
261 downgrade the version in this file.
262 https://rt.cpan.org/Ticket/Display.html?id=66250
263
264 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
265 that option for the directories that would normally go in
266 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

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

cb4f51d6
TC
433 used for color translation on Unix-like systems, and the fix
434 improves performance of supplying colors by name by about 80 times.

TC
1032 - the mask for ICO/CUR images is now applied as an alpha channel to
1033 the returned image. For the old behaviour, supply ico_masked => 0
1034 to read() or read_multi(). This should be less confusing when
1035 using Imager as a general image processor.

1038Bug fixes:

TC
1048 - to avoid confusion, channels not present in the image are returned as
1049 zero by getscanline(). This has no effect on the C level i_glin()
1050 and i_glinf() API functions which continue to not set the unused
1051 channels.

1193Imager 0.55 - 16 Dec 2006
1194===========
1195
1196This is primarily a bug fix release.
1197
1198Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1199
1200There is one new feature:
1201
1202 - the Win32 font driver now supports UTF8 (RT 22166)
1203 http://www.cpanforum.com/threads/3276
1204 http://rt.cpan.org/Ticket/Display.html?id=22166
1205
1206Several bugs were fixed:
1207
1208 - the string() method would not output the string "0"
1209 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1210
1211 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1212 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1213
1214 - the gif_disposal and gif_user_input tags weren't being read from
1215 the file correctly
1216 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1217
1218 - gif.c was failing to build under MSVC
1219 http://rt.cpan.org/Ticket/Display.html?id=23922
1220
1221 - in some cases strings passed to the string() method were treated as
1222 terminated by NUL (chr 0)
1223 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1224
1225 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1226 that's the default build name for zlib on Win32.
1227 http://rt.cpan.org/Ticket/Display.html?id=23064
1228
1229 - search $Config{incpath} for headers too, which we should have been
1230 doing all along.
1231
1232Win32 font driver fixes:
1233
1234 - the global descent value from bounding box was the wrong sign
1235 http://www.cpanforum.com/threads/3276
1236
1237 - if the first or last glyph overflowed the left or right side of the
1238 advance width they would be clipped
1239
1240
1241Imager 0.54 - 14 Sep 2006
1242===========
1243
1244This is primarily a feature release:
1245
1246 - a new qtype value 'mixing' has been added to the scale()
1247 method. This is faster than 'normal', slower than 'preview'. This
1248 is based on the method used by pnmscale, and seems to produce less
1249 blurry results than normal.
1250 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1251
1252 - the rubthrough() method can now render onto images with an alpha
1253 channel.
1254 http://rt.cpan.org/Ticket/Display.html?id=20678
1255
1256 - the read_multi() method now falls back to calling doing a single
1257 image read via the read() method and write_multi() will now fall
1258 back to calling write() if a single image is supplied. This means
1259 you can simply call the read_multi() or write_multi() functions
1260 without having to check if the type is formatted by that method.
1261 http://rt.cpan.org/Ticket/Display.html?id=19457
1262 http://rt.cpan.org/Ticket/Display.html?id=19458
1263
1264 - the GIF loop extension can now be written. If you don't have
1265 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1266 should upgrade.
1267 http://rt.cpan.org/Ticket/Display.html?id=21185
1268
1269 - getscanline() and setscanline() can now read/write palette index
1270 based data from/to the image for paletted images, by setting type to
1271 'index'.
1272 http://rt.cpan.org/Ticket/Display.html?id=20338
1273
1274 - we no longer hassle you to disable GIF support
1275 http://rt.cpan.org/Ticket/Display.html?id=20687
1276
1277 - minor documentation fixes
1278
1279
1280Imager 0.53 - 26 Jul 2006
1281===========
1282
1283This is a bugfix release.
1284
1285Some test code was left in a code path not covered by the test
1286suite. A test was added to cover this code path and the test code was
1287removed.

1291Imager 0.52 - 25 Jul 2006
1292===========
1293
1294This is primarily a feature release, but contains a fair few bug
1295fixes, new features:
1296
1297 - ability to read and write MS Windows ICO and CUR files
1298
1299 - you can now add file format plugins to support new file formats
1300
1301 - add POD coverage tests
1302
1303 - setcolors() and addcolors() now accept color names and so on
1304 instead of requiring Imager::Color objects.
1305 http://rt.cpan.org/Ticket/Display.html?id=20056
1306
1307 - flood_fill() can now fill to a specified border color instead of
1308 just to the area the same color as the seed.
1309 http://rt.cpan.org/Ticket/Display.html?id=19618
1310
1311
1312Bug fixes:
1313
1314 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1315 calculating the advance width.
1316 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1317
1318 - bounding_box for the T1 driver wasn't including leading and
1319 trailing spaces in the bounding box as the other drivers did, it also
1320 produced strange results for empty strings or strings containing only
1321 spaces
1322
1323 - when reading CMYK jpeg images they were being transferred to the
1324 image object as is, producing a four channel image. It only looked ok
1325 due to an old still unfixed Photoshop bug. We now convert from the
1326 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1327 http://rt.cpan.org/Ticket/Display.html?id=20416
1328
1329 - reading a CYMK TIFF would result in a 4 channel image, reading any
1330 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1331 result in an error.
1332 http://rt.cpan.org/Ticket/Display.html?id=20415
1333
1334 - added /usr/local/include to the default include search path, since
1335 we were already searching /usr/local/lib for libraries.
1336
1337And various minor fixes and documentation updates.
1338
1339
1340Imager 0.51 - 23 Apr 2006
1341===========

1344 a crash
1345 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1346
1347 - fix mis-processing of the src_maxx and src_maxy parameters of the
1348 paste() method
1349 http://rt.cpan.org/Public/Bug/Display.html?id=18712

1351 - fix a problem in Imager's "smart" handling of the color parameter
1352 to various methods.
1353 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1354
1355
1356Imager 0.50 - 29 Mar 2006
1357===========
1358
1359 - CRITICAL: fixes a segmentation fault from attempting to write a 2
