6d5c85a2 21==============
a7e32beb
TC
22
23 - add simple tests for the Imager::Test test_image generators
24
6d5c85a2
TC
25 - io_glue I/O buffering re-work:
26
27 - reorganize io_glue to do it's own buffering by default
28
29 - the unbuffered functions are available as i_io_raw_read() (or
30 raw_read() from perl) etc but are not recommended for typical
31 use.
32
33 - use the new i_io_peekn() when checking for file magic to avoid
34 seek, allowing Imager to detect the file type and read the file
35 from an unseekable stream (for formats that don't use random
36 access)
37
38 - added several new I/O layer API functions.
39
40 - fix the TGA performance problem, most noticably on Win32
41 https://rt.cpan.org/Ticket/Display.html?id=70037
42
43 - TIFF now uses wrapper functions of the correct types to avoid casts
44 https://rt.cpan.org/Ticket/Display.html?id=69912
45
46 - the callback IO object did its own buffering, controlled by the
47 maxbuffer parameter supplied to the read() and write() methods.
48 This buffering has been removed, to avoid redundancy with the
49 common io_glue buffering. This also avoids a bug in that code
50 which could rarely pass a zero length to the read callback and
51 then panic about the result.
52
53 - the callback IO object now tests the result of calling the close
54 callback, which should return true for success.
55
56 - the PNM reader did its own buffering. This buffering has been
57 removed to avoid redundancy with the common io_glue buffering.
58
59 - previously the read handlers for fd and callback I/O layers would
60 call the underlying interface (POSIX read or your supplied callback)
61 until it filled the buffer. It now only makes one call.
62
63 - added public constructors for I/O layer objects (see Imager::IO)
64
65 - all core file handlers now use the i_io_foo() wrappers to gain
66 access to buffered I/O rather than calling the I/O layer
67 callbacks directly.
68
69 - all core file handlers now check for error on close.
70
71 - Backward compatibility: if you hava custom file handlers, you can
72 use i_io_write() etc since they're available as macros in older
73 versions of Imager.
74
75 - eliminate the final remnants of io_glue_commit_types().
76
77 - bump IMAGER_API_VERSION, since the above may break assumptions.
78
79 - removed the long unused i_gen_reader() and i_gen_writer() utility
80 functions.

6ad7e4bc
TC
83===========
84
0c647c9a
TC
85The main changes in the release versus 0.84 are:
86
87 - on 64-bit systems, 64-bit types are consistently used for image
88 dimensions and co-ordinated, and for memory block sizes.
89
90 - handle IFD loops in TIFF files correctly. Previously this would
91 lead to an infinite loop.
92
6ad7e4bc
TC
93Bug fixes:
94
95 - fix the link in the getheight() entry in the method index

100Development release, this will become 0.85 if CPAN testers is
101favourable.
6b7197d0
TC
102
103Bug fixes:
104
105 - the image file limits set by set_file_limits() weren't being
106 checked when reading TIFF files.
107 https://rt.cpan.org/Ticket/Display.html?id=69915
108
5970bd39
TC
109 - Provide more information about file format module load errors on a
110 failed image file read() or write().
111 https://rt.cpan.org/Ticket/Display.html?id=69194
112
4ce3551c
TC
113 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
114 through TIFF images, since it checks for IFD loops.
115 https://rt.cpan.org/Ticket/Display.html?id=69914
116
a16bca6d
TC
117 - don't leak memory when out of range palette indexes are supplied to
118 setscanline().
119 https://rt.cpan.org/Ticket/Display.html?id=69242
120
121 - require a later version of CPAN::Meta to ensure JSON::PP and
122 CPAN::Meta::YAML are available.
123 https://rt.cpan.org/Ticket/Display.html?id=69008
124
ac575c5f
TC
125 - hoist the per-line calculations for the flines implementations, and
126 modernize the tests a bit.
127 https://rt.cpan.org/Ticket/Display.html?id=70126
128
86c8d19a
TC
129 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
130 them when available.
131 https://rt.cpan.org/Ticket/Display.html?id=69147
132
a3fd7df7
TC
133 - if t1lib failed to reinitialize it would be left as marked

140Imager 0.84_01 - 8 Aug 2011
141==============
142
143Development release as a sanity check for the types re-work.
8d14daab
TC
144
145Massive types re-work:
146
147 - the type used internally for pixel co-ordinates and image sizes is
148 now 64-bit on 64-bit platforms (at least sane ones).
149
150 - size_t is now used consistently for memory block sizes.
151
152 - since this changes the binary interface, the Imager API version has
153 been incremented. Any module that uses the API will need to be
154 rebuilt. In most cases that will be enough, but calls to any APIs
155 that take a pointer to image sizes may need source changes.
156
157 - you should be able to create very large images on 64-bit systems,
158 if you have enough memory. Successfully created a 32768 x 49192 x
159 3 channel image, filled with a tiled image and scaled it. The
160 unscaled image was also successfully saved to a JPEG.
161
162 - check the image size before attempting to write BMP, GIF, JPEG,
163 PNG, SGI, TGA, TIFF images.
164
165 - correctly handle reading TGA images over 32767 pixels wide or tall.
166
167Incidental changes:
168
169 - the gif_left and gif_top tags are now clamped to non-negative
170 values when writing a GIF image.
171
172 - removed dead callback read/write code
173
174The default maximum memory size when reading files is now 1G.

b1e66a82
TC
177===========
178
179 - Imager no longer inherits from Exporter (unless you're running an
180 old, old perl.
181
92e9df65
TC
182 - Imager can now write progressive JPEGs (it could always read them).
183 https://rt.cpan.org/Ticket/Display.html?id=68691
184
10ea52a3
TC
185Bug fixes:
186

200
6d068d36
TC
201 - convert colors to grayscale if the supplied (or generated) palette
202 contains only grays when performing error diffusion color
203 translation.
204 https://rt.cpan.org/Ticket/Display.html?id=68508
205
59c150a4
TC
206 - writing a paletted image to GIF wouldn't always use the colors
207 supplied (or generated, eg. via make_colors => "mono"), which was
208 confusing at best.
209 https://rt.cpan.org/Ticket/Display.html?id=67912
210
5b480b14
TC
211 - replace (imager|tony)@imager.perl.org in the doc, since I don't
212 plan to continue receiving mail at that address.

227Dev release, in case the compose tests are too sensitive.
deb1a916
TC
228
229Bug fixes:
230
231 - Imager::Font::T1 incorrectly checked for absolute filename under
232 Win32. Thanks to kmx for the report and fix.
233 https://rt.cpan.org/Ticket/Display.html?id=67963
234
618a3282
TC
235 - compose() with the target, source or mask position off the top or
236 left of the target image didn't clip the source image correctly.
237 https://rt.cpan.org/Ticket/Display.html?id=67220
238
239 - compose() now returns a useful error message on a non-positive
240 opacity.
241
242 - compose.im now at 100% test coverage. (As opposed to, umm, much,
243 much less.)

c1d16c8f 245Imager 0.82 - 14 Mar 2011
2368cfec
TC
246===========
247
248Bug fixes:
249
250 - eliminate calls to i_has_format() from the test suite, since it's
251 no longer a useful way to check for file format support. Eliminate
252 i_has_format() from the functions exposed via XS.
253 https://rt.cpan.org/Ticket/Display.html?id=65863
254
7540f84a
TC
255 - eliminate calls to note(), which isn't in the (very old) version of
256 Test::More we have as a pre-requisite. note() is modern enough
257 that I don't feel a need to require a Test::More upgrade for it.
258 https://rt.cpan.org/Ticket/Display.html?id=65864
259
81984f30
TC
260 - skip the threads tests on Test::More 2.00_*

268
c901f27d
TC
269 - increase the version of Imager::Font::Type1 so that upgrades don't
270 downgrade the version in this file.
271 https://rt.cpan.org/Ticket/Display.html?id=66250
272
273 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
274 that option for the directories that would normally go in
275 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

337 just a little darker.
338
9a5df694
TC
339 - make the default color map build algorithm "mediancut". This
340 changes the default color map builder for writing GIFs back to what
341 it was in 0.77, reverting a performance regression.

351
2a2c791f
TC
352 - the convert() method now optimizes the case where all output
353 channels are either 0, sourced from a single input channel or 1.
354 This significantly speeds up presets like "addalpha", "green".
355 https://rt.cpan.org/Ticket/Display.html?id=51254

440
173c91ba 441 - fix the cache check for the X rgb.txt loader. This is typically
cb4f51d6
TC
442 used for color translation on Unix-like systems, and the fix
443 improves performance of supplying colors by name by about 80 times.
444 Test code that managed 3400 10x10 pixel boxes/second sped up to
445 25700 boxes/second.

824 noalpha channels or back.
825 https://rt.cpan.org/Ticket/Display.html?id=30908
826
827 - rubthrough() now falls back to pasting when the source doesn't have
828 an alpha channel. This effectively treats the source as having a
829 max alpha channel, the right thing to do.
830 http://rt.cpan.org/Ticket/Display.html?id=29944

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

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

1202Imager 0.55 - 16 Dec 2006
1203===========
1204
1205This is primarily a bug fix release.
1206
1207Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1208
1209There is one new feature:
1210
1211 - the Win32 font driver now supports UTF8 (RT 22166)
1212 http://www.cpanforum.com/threads/3276
1213 http://rt.cpan.org/Ticket/Display.html?id=22166
1214
1215Several bugs were fixed:
1216
1217 - the string() method would not output the string "0"
1218 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1219
1220 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1221 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1222
1223 - the gif_disposal and gif_user_input tags weren't being read from
1224 the file correctly
1225 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1226
1227 - gif.c was failing to build under MSVC
1228 http://rt.cpan.org/Ticket/Display.html?id=23922
1229
1230 - in some cases strings passed to the string() method were treated as
1231 terminated by NUL (chr 0)
1232 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1233
1234 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1235 that's the default build name for zlib on Win32.
1236 http://rt.cpan.org/Ticket/Display.html?id=23064
1237
1238 - search $Config{incpath} for headers too, which we should have been
1239 doing all along.
1240
1241Win32 font driver fixes:
1242
1243 - the global descent value from bounding box was the wrong sign
1244 http://www.cpanforum.com/threads/3276
1245
1246 - if the first or last glyph overflowed the left or right side of the
1247 advance width they would be clipped
1248
1249
1250Imager 0.54 - 14 Sep 2006
1251===========
1252
1253This is primarily a feature release:
1254
1255 - a new qtype value 'mixing' has been added to the scale()
1256 method. This is faster than 'normal', slower than 'preview'. This
1257 is based on the method used by pnmscale, and seems to produce less
1258 blurry results than normal.
1259 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1260
1261 - the rubthrough() method can now render onto images with an alpha
1262 channel.
1263 http://rt.cpan.org/Ticket/Display.html?id=20678
1264
1265 - the read_multi() method now falls back to calling doing a single
1266 image read via the read() method and write_multi() will now fall
1267 back to calling write() if a single image is supplied. This means
1268 you can simply call the read_multi() or write_multi() functions
1269 without having to check if the type is formatted by that method.
1270 http://rt.cpan.org/Ticket/Display.html?id=19457
1271 http://rt.cpan.org/Ticket/Display.html?id=19458
1272
1273 - the GIF loop extension can now be written. If you don't have
1274 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1275 should upgrade.
1276 http://rt.cpan.org/Ticket/Display.html?id=21185
1277
1278 - getscanline() and setscanline() can now read/write palette index
1279 based data from/to the image for paletted images, by setting type to
1280 'index'.
1281 http://rt.cpan.org/Ticket/Display.html?id=20338
1282
1283 - we no longer hassle you to disable GIF support
1284 http://rt.cpan.org/Ticket/Display.html?id=20687
1285
1286 - minor documentation fixes
1287
1288
1289Imager 0.53 - 26 Jul 2006
1290===========
1291
1292This is a bugfix release.
1293
1294Some test code was left in a code path not covered by the test
1295suite. A test was added to cover this code path and the test code was
1296removed.

1300Imager 0.52 - 25 Jul 2006
1301===========
1302
1303This is primarily a feature release, but contains a fair few bug
1304fixes, new features:
1305
1306 - ability to read and write MS Windows ICO and CUR files
1307
1308 - you can now add file format plugins to support new file formats
1309
1310 - add POD coverage tests
1311
1312 - setcolors() and addcolors() now accept color names and so on
1313 instead of requiring Imager::Color objects.
1314 http://rt.cpan.org/Ticket/Display.html?id=20056
1315
1316 - flood_fill() can now fill to a specified border color instead of
1317 just to the area the same color as the seed.
1318 http://rt.cpan.org/Ticket/Display.html?id=19618
1319
1320
1321Bug fixes:
1322
1323 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1324 calculating the advance width.
1325 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1326
1327 - bounding_box for the T1 driver wasn't including leading and
1328 trailing spaces in the bounding box as the other drivers did, it also
1329 produced strange results for empty strings or strings containing only
1330 spaces
1331
1332 - when reading CMYK jpeg images they were being transferred to the
1333 image object as is, producing a four channel image. It only looked ok
1334 due to an old still unfixed Photoshop bug. We now convert from the
1335 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1336 http://rt.cpan.org/Ticket/Display.html?id=20416
1337
1338 - reading a CYMK TIFF would result in a 4 channel image, reading any
1339 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1340 result in an error.
1341 http://rt.cpan.org/Ticket/Display.html?id=20415
1342
1343 - added /usr/local/include to the default include search path, since
1344 we were already searching /usr/local/lib for libraries.
1345
1346And various minor fixes and documentation updates.
1347
1348
1349Imager 0.51 - 23 Apr 2006
