31be6e9a 3Imager 0.85_01 - 10 Oct 2011
6d5c85a2 4==============
a7e32beb
TC
5
6 - add simple tests for the Imager::Test test_image generators
7
6d5c85a2
TC
8 - io_glue I/O buffering re-work:
9
10 - reorganize io_glue to do it's own buffering by default
11
12 - the unbuffered functions are available as i_io_raw_read() (or
13 raw_read() from perl) etc but are not recommended for typical
14 use.
15
16 - use the new i_io_peekn() when checking for file magic to avoid
17 seek, allowing Imager to detect the file type and read the file
18 from an unseekable stream (for formats that don't use random
19 access)
20
21 - added several new I/O layer API functions.
22
23 - fix the TGA performance problem, most noticably on Win32
24 https://rt.cpan.org/Ticket/Display.html?id=70037
25
26 - TIFF now uses wrapper functions of the correct types to avoid casts
27 https://rt.cpan.org/Ticket/Display.html?id=69912
28
29 - the callback IO object did its own buffering, controlled by the
30 maxbuffer parameter supplied to the read() and write() methods.
31 This buffering has been removed, to avoid redundancy with the
32 common io_glue buffering. This also avoids a bug in that code
33 which could rarely pass a zero length to the read callback and
34 then panic about the result.
35
36 - the callback IO object now tests the result of calling the close
37 callback, which should return true for success.
38
39 - the PNM reader did its own buffering. This buffering has been
40 removed to avoid redundancy with the common io_glue buffering.
41
42 - previously the read handlers for fd and callback I/O layers would
43 call the underlying interface (POSIX read or your supplied callback)
44 until it filled the buffer. It now only makes one call.
45
46 - added public constructors for I/O layer objects (see Imager::IO)
47
48 - all core file handlers now use the i_io_foo() wrappers to gain
49 access to buffered I/O rather than calling the I/O layer
50 callbacks directly.
51
52 - all core file handlers now check for error on close.
53
54 - Backward compatibility: if you hava custom file handlers, you can
55 use i_io_write() etc since they're available as macros in older
56 versions of Imager.
57
58 - eliminate the final remnants of io_glue_commit_types().
59
60 - bump IMAGER_API_VERSION, since the above may break assumptions.
61
62 - removed the long unused i_gen_reader() and i_gen_writer() utility
63 functions.

6ad7e4bc
TC
66===========
67
0c647c9a
TC
68The main changes in the release versus 0.84 are:
69
70 - on 64-bit systems, 64-bit types are consistently used for image
71 dimensions and co-ordinated, and for memory block sizes.
72
73 - handle IFD loops in TIFF files correctly. Previously this would
74 lead to an infinite loop.
75
6ad7e4bc
TC
76Bug fixes:
77
78 - fix the link in the getheight() entry in the method index

80Imager 0.84_02 - 22 Aug 2011
81==============
82
83Development release, this will become 0.85 if CPAN testers is
84favourable.
6b7197d0
TC
85
86Bug fixes:
87
88 - the image file limits set by set_file_limits() weren't being
89 checked when reading TIFF files.
90 https://rt.cpan.org/Ticket/Display.html?id=69915
91
5970bd39
TC
92 - Provide more information about file format module load errors on a
93 failed image file read() or write().
94 https://rt.cpan.org/Ticket/Display.html?id=69194
95
4ce3551c
TC
96 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
97 through TIFF images, since it checks for IFD loops.
98 https://rt.cpan.org/Ticket/Display.html?id=69914
99
a16bca6d
TC
100 - don't leak memory when out of range palette indexes are supplied to
101 setscanline().
102 https://rt.cpan.org/Ticket/Display.html?id=69242
103
104 - require a later version of CPAN::Meta to ensure JSON::PP and
105 CPAN::Meta::YAML are available.
106 https://rt.cpan.org/Ticket/Display.html?id=69008
107
ac575c5f
TC
108 - hoist the per-line calculations for the flines implementations, and
109 modernize the tests a bit.
110 https://rt.cpan.org/Ticket/Display.html?id=70126
111
86c8d19a
TC
112 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
113 them when available.
114 https://rt.cpan.org/Ticket/Display.html?id=69147
115
a3fd7df7
TC
116 - if t1lib failed to reinitialize it would be left as marked

123Imager 0.84_01 - 8 Aug 2011
124==============
125
126Development release as a sanity check for the types re-work.
8d14daab
TC
127
128Massive types re-work:
129
130 - the type used internally for pixel co-ordinates and image sizes is
131 now 64-bit on 64-bit platforms (at least sane ones).
132
133 - size_t is now used consistently for memory block sizes.
134
135 - since this changes the binary interface, the Imager API version has
136 been incremented. Any module that uses the API will need to be
137 rebuilt. In most cases that will be enough, but calls to any APIs
138 that take a pointer to image sizes may need source changes.
139
140 - you should be able to create very large images on 64-bit systems,
141 if you have enough memory. Successfully created a 32768 x 49192 x
142 3 channel image, filled with a tiled image and scaled it. The
143 unscaled image was also successfully saved to a JPEG.
144
145 - check the image size before attempting to write BMP, GIF, JPEG,
146 PNG, SGI, TGA, TIFF images.
147
148 - correctly handle reading TGA images over 32767 pixels wide or tall.
149
150Incidental changes:
151
152 - the gif_left and gif_top tags are now clamped to non-negative
153 values when writing a GIF image.
154
155 - removed dead callback read/write code
156
157The default maximum memory size when reading files is now 1G.

b1e66a82
TC
160===========
161
162 - Imager no longer inherits from Exporter (unless you're running an
163 old, old perl.
164
92e9df65
TC
165 - Imager can now write progressive JPEGs (it could always read them).

167
10ea52a3
TC
168Bug fixes:
169

181 - Imager no longer exports anything by default
182 https://rt.cpan.org/Ticket/Display.html?id=65228
183
6d068d36
TC
184 - convert colors to grayscale if the supplied (or generated) palette
185 contains only grays when performing error diffusion color
186 translation.
187 https://rt.cpan.org/Ticket/Display.html?id=68508
188
59c150a4
TC
189 - writing a paletted image to GIF wouldn't always use the colors
190 supplied (or generated, eg. via make_colors => "mono"), which was
191 confusing at best.
192 https://rt.cpan.org/Ticket/Display.html?id=67912
193
5b480b14
TC
194 - replace (imager|tony)@imager.perl.org in the doc, since I don't
195 plan to continue receiving mail at that address.

210Dev release, in case the compose tests are too sensitive.
deb1a916
TC
211
212Bug fixes:
213
214 - Imager::Font::T1 incorrectly checked for absolute filename under
215 Win32. Thanks to kmx for the report and fix.
216 https://rt.cpan.org/Ticket/Display.html?id=67963
217
618a3282
TC
218 - compose() with the target, source or mask position off the top or
219 left of the target image didn't clip the source image correctly.
220 https://rt.cpan.org/Ticket/Display.html?id=67220
221
222 - compose() now returns a useful error message on a non-positive
223 opacity.
224
225 - compose.im now at 100% test coverage. (As opposed to, umm, much,
226 much less.)

2368cfec
TC
229===========
230
231Bug fixes:
232
233 - eliminate calls to i_has_format() from the test suite, since it's
234 no longer a useful way to check for file format support. Eliminate
235 i_has_format() from the functions exposed via XS.
236 https://rt.cpan.org/Ticket/Display.html?id=65863
237
7540f84a
TC
238 - eliminate calls to note(), which isn't in the (very old) version of
239 Test::More we have as a pre-requisite. note() is modern enough
240 that I don't feel a need to require a Test::More upgrade for it.
241 https://rt.cpan.org/Ticket/Display.html?id=65864
242
81984f30
TC
243 - skip the threads tests on Test::More 2.00_*

252 - increase the version of Imager::Font::Type1 so that upgrades don't
253 downgrade the version in this file.
254 https://rt.cpan.org/Ticket/Display.html?id=66250
255
256 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
257 that option for the directories that would normally go in
258 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

320 just a little darker.
321
9a5df694
TC
322 - make the default color map build algorithm "mediancut". This
323 changes the default color map builder for writing GIFs back to what
324 it was in 0.77, reverting a performance regression.

336 channels are either 0, sourced from a single input channel or 1.
337 This significantly speeds up presets like "addalpha", "green".
338 https://rt.cpan.org/Ticket/Display.html?id=51254

423
173c91ba 424 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
425 used for color translation on Unix-like systems, and the fix
426 improves performance of supplying colors by name by about 80 times.
427 Test code that managed 3400 10x10 pixel boxes/second sped up to
428 25700 boxes/second.

808 https://rt.cpan.org/Ticket/Display.html?id=30908
809
810 - rubthrough() now falls back to pasting when the source doesn't have
811 an alpha channel. This effectively treats the source as having a
812 max alpha channel, the right thing to do.

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

1185Imager 0.55 - 16 Dec 2006
1186===========
1187
1188This is primarily a bug fix release.
1189
1190Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1191
1192There is one new feature:
1193
1194 - the Win32 font driver now supports UTF8 (RT 22166)
1195 http://www.cpanforum.com/threads/3276
1196 http://rt.cpan.org/Ticket/Display.html?id=22166
1197
1198Several bugs were fixed:
1199
1200 - the string() method would not output the string "0"
1201 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1202
1203 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1204 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1205
1206 - the gif_disposal and gif_user_input tags weren't being read from
1207 the file correctly
1208 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1209
1210 - gif.c was failing to build under MSVC
1211 http://rt.cpan.org/Ticket/Display.html?id=23922
1212
1213 - in some cases strings passed to the string() method were treated as
1214 terminated by NUL (chr 0)
1215 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1216
1217 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1218 that's the default build name for zlib on Win32.
1219 http://rt.cpan.org/Ticket/Display.html?id=23064
1220
1221 - search $Config{incpath} for headers too, which we should have been
1222 doing all along.
1223
1224Win32 font driver fixes:
1225
1226 - the global descent value from bounding box was the wrong sign
1227 http://www.cpanforum.com/threads/3276
1228
1229 - if the first or last glyph overflowed the left or right side of the
1230 advance width they would be clipped
1231
1232
1233Imager 0.54 - 14 Sep 2006
1234===========
1235
1236This is primarily a feature release:
1237
1238 - a new qtype value 'mixing' has been added to the scale()
1239 method. This is faster than 'normal', slower than 'preview'. This
1240 is based on the method used by pnmscale, and seems to produce less
1241 blurry results than normal.
1242 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1243
1244 - the rubthrough() method can now render onto images with an alpha
1245 channel.
1246 http://rt.cpan.org/Ticket/Display.html?id=20678
1247
1248 - the read_multi() method now falls back to calling doing a single
1249 image read via the read() method and write_multi() will now fall
1250 back to calling write() if a single image is supplied. This means
1251 you can simply call the read_multi() or write_multi() functions
1252 without having to check if the type is formatted by that method.
1253 http://rt.cpan.org/Ticket/Display.html?id=19457
1254 http://rt.cpan.org/Ticket/Display.html?id=19458
1255
1256 - the GIF loop extension can now be written. If you don't have
1257 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1258 should upgrade.
1259 http://rt.cpan.org/Ticket/Display.html?id=21185
1260
1261 - getscanline() and setscanline() can now read/write palette index
1262 based data from/to the image for paletted images, by setting type to
1263 'index'.
1264 http://rt.cpan.org/Ticket/Display.html?id=20338
1265
1266 - we no longer hassle you to disable GIF support
1267 http://rt.cpan.org/Ticket/Display.html?id=20687
1268
1269 - minor documentation fixes
1270
1271
1272Imager 0.53 - 26 Jul 2006
1273===========
1274
1275This is a bugfix release.
1276
1277Some test code was left in a code path not covered by the test
1278suite. A test was added to cover this code path and the test code was
1279removed.

1282
1283Imager 0.52 - 25 Jul 2006
1284===========
1285
1286This is primarily a feature release, but contains a fair few bug
1287fixes, new features:
1288
1289 - ability to read and write MS Windows ICO and CUR files
1290
1291 - you can now add file format plugins to support new file formats
1292
1293 - add POD coverage tests
1294
1295 - setcolors() and addcolors() now accept color names and so on
1296 instead of requiring Imager::Color objects.
1297 http://rt.cpan.org/Ticket/Display.html?id=20056
1298
1299 - flood_fill() can now fill to a specified border color instead of
1300 just to the area the same color as the seed.
1301 http://rt.cpan.org/Ticket/Display.html?id=19618
1302
1303
1304Bug fixes:
1305
1306 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1307 calculating the advance width.
1308 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1309
1310 - bounding_box for the T1 driver wasn't including leading and
1311 trailing spaces in the bounding box as the other drivers did, it also
1312 produced strange results for empty strings or strings containing only
1313 spaces
1314
1315 - when reading CMYK jpeg images they were being transferred to the
1316 image object as is, producing a four channel image. It only looked ok
1317 due to an old still unfixed Photoshop bug. We now convert from the
1318 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1319 http://rt.cpan.org/Ticket/Display.html?id=20416
1320
1321 - reading a CYMK TIFF would result in a 4 channel image, reading any
1322 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1323 result in an error.
1324 http://rt.cpan.org/Ticket/Display.html?id=20415
1325
1326 - added /usr/local/include to the default include search path, since
1327 we were already searching /usr/local/lib for libraries.
1328
1329And various minor fixes and documentation updates.
1330
1331
1332Imager 0.51 - 23 Apr 2006
