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

TC
92===========
93
0c647c9a
TC
94The main changes in the release versus 0.84 are:
95
96 - on 64-bit systems, 64-bit types are consistently used for image
97 dimensions and co-ordinated, and for memory block sizes.
98
99 - handle IFD loops in TIFF files correctly. Previously this would
100 lead to an infinite loop.
101
6ad7e4bc
TC
102Bug fixes:

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

149Imager 0.84_01 - 8 Aug 2011
150==============
151
152Development release as a sanity check for the types re-work.
8d14daab
TC
153
154Massive types re-work:
155
156 - the type used internally for pixel co-ordinates and image sizes is
157 now 64-bit on 64-bit platforms (at least sane ones).
158
159 - size_t is now used consistently for memory block sizes.
160
161 - since this changes the binary interface, the Imager API version has
162 been incremented. Any module that uses the API will need to be
163 rebuilt. In most cases that will be enough, but calls to any APIs
164 that take a pointer to image sizes may need source changes.
165
166 - you should be able to create very large images on 64-bit systems,
167 if you have enough memory. Successfully created a 32768 x 49192 x
168 3 channel image, filled with a tiled image and scaled it. The
169 unscaled image was also successfully saved to a JPEG.
170
171 - check the image size before attempting to write BMP, GIF, JPEG,
172 PNG, SGI, TGA, TIFF images.
173
174 - correctly handle reading TGA images over 32767 pixels wide or tall.
175
176Incidental changes:
177
178 - the gif_left and gif_top tags are now clamped to non-negative
179 values when writing a GIF image.
180
181 - removed dead callback read/write code
182
183The default maximum memory size when reading files is now 1G.

b1e66a82
TC
186===========
187
188 - Imager no longer inherits from Exporter (unless you're running an
189 old, old perl.
190
92e9df65
TC
191 - Imager can now write progressive JPEGs (it could always read them).

TC
194Bug fixes:

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

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

2368cfec
TC
255===========
256
257Bug fixes:
258
259 - eliminate calls to i_has_format() from the test suite, since it's
260 no longer a useful way to check for file format support. Eliminate
261 i_has_format() from the functions exposed via XS.
262 https://rt.cpan.org/Ticket/Display.html?id=65863
263
7540f84a
TC
264 - eliminate calls to note(), which isn't in the (very old) version of
265 Test::More we have as a pre-requisite. note() is modern enough
266 that I don't feel a need to require a Test::More upgrade for it.
267 https://rt.cpan.org/Ticket/Display.html?id=65864
268
81984f30
TC
269 - skip the threads tests on Test::More 2.00_*

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

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

cb4f51d6
TC
451 used for color translation on Unix-like systems, and the fix

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

890 problem with loading such an image. I haven't been able to find any
891 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
892 I'll match it's behaviour. See issue 114913 in the GIMP's

1211Imager 0.55 - 16 Dec 2006
1212===========
1213
1214This is primarily a bug fix release.
1215
1216Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1217
1218There is one new feature:
1219
1220 - the Win32 font driver now supports UTF8 (RT 22166)
1221 http://www.cpanforum.com/threads/3276
1222 http://rt.cpan.org/Ticket/Display.html?id=22166
1223
1224Several bugs were fixed:
1225
1226 - the string() method would not output the string "0"
1227 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1228
1229 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1230 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1231
1232 - the gif_disposal and gif_user_input tags weren't being read from
1233 the file correctly
1234 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1235
1236 - gif.c was failing to build under MSVC
1237 http://rt.cpan.org/Ticket/Display.html?id=23922
1238
1239 - in some cases strings passed to the string() method were treated as
1240 terminated by NUL (chr 0)
1241 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1242
1243 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1244 that's the default build name for zlib on Win32.
1245 http://rt.cpan.org/Ticket/Display.html?id=23064
1246
1247 - search $Config{incpath} for headers too, which we should have been
1248 doing all along.
1249
1250Win32 font driver fixes:
1251
1252 - the global descent value from bounding box was the wrong sign
1253 http://www.cpanforum.com/threads/3276
1254
1255 - if the first or last glyph overflowed the left or right side of the
1256 advance width they would be clipped
1257
1258
1259Imager 0.54 - 14 Sep 2006
1260===========
1261
1262This is primarily a feature release:
1263
1264 - a new qtype value 'mixing' has been added to the scale()
1265 method. This is faster than 'normal', slower than 'preview'. This
1266 is based on the method used by pnmscale, and seems to produce less
1267 blurry results than normal.
1268 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1269
1270 - the rubthrough() method can now render onto images with an alpha
1271 channel.
1272 http://rt.cpan.org/Ticket/Display.html?id=20678
1273
1274 - the read_multi() method now falls back to calling doing a single
1275 image read via the read() method and write_multi() will now fall
1276 back to calling write() if a single image is supplied. This means
1277 you can simply call the read_multi() or write_multi() functions
1278 without having to check if the type is formatted by that method.
1279 http://rt.cpan.org/Ticket/Display.html?id=19457
1280 http://rt.cpan.org/Ticket/Display.html?id=19458
1281
1282 - the GIF loop extension can now be written. If you don't have
1283 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1284 should upgrade.
1285 http://rt.cpan.org/Ticket/Display.html?id=21185
1286
1287 - getscanline() and setscanline() can now read/write palette index
1288 based data from/to the image for paletted images, by setting type to
1289 'index'.
1290 http://rt.cpan.org/Ticket/Display.html?id=20338
1291
1292 - we no longer hassle you to disable GIF support
1293 http://rt.cpan.org/Ticket/Display.html?id=20687
1294
1295 - minor documentation fixes
1296
1297
1298Imager 0.53 - 26 Jul 2006
1299===========
1300
1301This is a bugfix release.
1302
1303Some test code was left in a code path not covered by the test
1304suite. A test was added to cover this code path and the test code was
1305removed.

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