84
85 - add simple tests for the Imager::Test test_image generators
86

TC
87 - io_glue I/O buffering re-work:
88
89 - reorganize io_glue to do it's own buffering by default
90
91 - the unbuffered functions are available as i_io_raw_read() (or
92 raw_read() from perl) etc but are not recommended for typical
93 use.
94
95 - use the new i_io_peekn() when checking for file magic to avoid
96 seek, allowing Imager to detect the file type and read the file
97 from an unseekable stream (for formats that don't use random
98 access)
99
100 - added several new I/O layer API functions.
101
102 - fix the TGA performance problem, most noticably on Win32
103 https://rt.cpan.org/Ticket/Display.html?id=70037
104
105 - TIFF now uses wrapper functions of the correct types to avoid casts
106 https://rt.cpan.org/Ticket/Display.html?id=69912
107
108 - the callback IO object did its own buffering, controlled by the
109 maxbuffer parameter supplied to the read() and write() methods.
110 This buffering has been removed, to avoid redundancy with the
111 common io_glue buffering. This also avoids a bug in that code
112 which could rarely pass a zero length to the read callback and
113 then panic about the result.
114
115 - the callback IO object now tests the result of calling the close
116 callback, which should return true for success.
117
118 - the PNM reader did its own buffering. This buffering has been
119 removed to avoid redundancy with the common io_glue buffering.
120
121 - previously the read handlers for fd and callback I/O layers would
122 call the underlying interface (POSIX read or your supplied callback)
123 until it filled the buffer. It now only makes one call.
124
125 - added public constructors for I/O layer objects (see Imager::IO)
126
127 - all core file handlers now use the i_io_foo() wrappers to gain
128 access to buffered I/O rather than calling the I/O layer
129 callbacks directly.
130
131 - all core file handlers now check for error on close.
132
133 - Backward compatibility: if you hava custom file handlers, you can
134 use i_io_write() etc since they're available as macros in older
135 versions of Imager.
136
137 - eliminate the final remnants of io_glue_commit_types().
138
139 - bump IMAGER_API_VERSION, since the above may break assumptions.
140
141 - removed the long unused i_gen_reader() and i_gen_writer() utility
142 functions.

0c647c9a
TC
147The main changes in the release versus 0.84 are:
148
149 - on 64-bit systems, 64-bit types are consistently used for image
150 dimensions and co-ordinated, and for memory block sizes.
151
152 - handle IFD loops in TIFF files correctly. Previously this would
153 lead to an infinite loop.

202Imager 0.84_01 - 8 Aug 2011
203==============
204
205Development release as a sanity check for the types re-work.
8d14daab
TC
206
207Massive types re-work:
208
209 - the type used internally for pixel co-ordinates and image sizes is
210 now 64-bit on 64-bit platforms (at least sane ones).
211
212 - size_t is now used consistently for memory block sizes.
213
214 - since this changes the binary interface, the Imager API version has
215 been incremented. Any module that uses the API will need to be
216 rebuilt. In most cases that will be enough, but calls to any APIs
217 that take a pointer to image sizes may need source changes.
218
219 - you should be able to create very large images on 64-bit systems,
220 if you have enough memory. Successfully created a 32768 x 49192 x
221 3 channel image, filled with a tiled image and scaled it. The
222 unscaled image was also successfully saved to a JPEG.
223
224 - check the image size before attempting to write BMP, GIF, JPEG,
225 PNG, SGI, TGA, TIFF images.
226
227 - correctly handle reading TGA images over 32767 pixels wide or tall.
228
229Incidental changes:
230
231 - the gif_left and gif_top tags are now clamped to non-negative
232 values when writing a GIF image.
233
234 - removed dead callback read/write code
235
236The default maximum memory size when reading files is now 1G.

265 translation.

59c150a4

268 - writing a paletted image to GIF wouldn't always use the colors

317 - eliminate calls to note(), which isn't in the (very old) version of

334
335 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
336 that option for the directories that would normally go in

889 - rubthrough() now falls back to pasting when the source doesn't have
890 an alpha channel. This effectively treats the source as having a
891 max alpha channel, the right thing to do.

937 - some TGA images weren't being detected correctly as TGA images
938 https://rt.cpan.org/Ticket/Display.html?id=32925
939
940 - handling of the left-over bit for 16-bit/pixel TGA images has been
941 changed to match the behaviour of the GIMP. Previously the bit
942 being set was treated as an opaque pixel, but one user reported a
943 problem with loading such an image. I haven't been able to find any
944 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
945 I'll match it's behaviour. See issue 114913 in the GIMP's
946 bugzilla.

1268
1269Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1270
1271There is one new feature:

1275 http://rt.cpan.org/Ticket/Display.html?id=22166

1278
1279 - the string() method would not output the string "0"
1280 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1281
1282 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1283 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1284
1285 - the gif_disposal and gif_user_input tags weren't being read from
1286 the file correctly
1287 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1288
1289 - gif.c was failing to build under MSVC
1290 http://rt.cpan.org/Ticket/Display.html?id=23922
1291
1292 - in some cases strings passed to the string() method were treated as
1293 terminated by NUL (chr 0)
1294 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1295
1296 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1297 that's the default build name for zlib on Win32.
1298 http://rt.cpan.org/Ticket/Display.html?id=23064
1299
1300 - search $Config{incpath} for headers too, which we should have been
1301 doing all along.
1302
1303Win32 font driver fixes:
1304
1305 - the global descent value from bounding box was the wrong sign
1306 http://www.cpanforum.com/threads/3276
1307

1309 advance width they would be clipped

1311
1312Imager 0.54 - 14 Sep 2006
1313===========
1314
1315This is primarily a feature release:
1316
1317 - a new qtype value 'mixing' has been added to the scale()
1318 method. This is faster than 'normal', slower than 'preview'. This
1319 is based on the method used by pnmscale, and seems to produce less
1320 blurry results than normal.
1321 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1322
1323 - the rubthrough() method can now render onto images with an alpha
1324 channel.
1325 http://rt.cpan.org/Ticket/Display.html?id=20678
1326
1327 - the read_multi() method now falls back to calling doing a single
1328 image read via the read() method and write_multi() will now fall
1329 back to calling write() if a single image is supplied. This means
1330 you can simply call the read_multi() or write_multi() functions
1331 without having to check if the type is formatted by that method.
1332 http://rt.cpan.org/Ticket/Display.html?id=19457
1333 http://rt.cpan.org/Ticket/Display.html?id=19458
1334
1335 - the GIF loop extension can now be written. If you don't have
1336 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1337 should upgrade.
1338 http://rt.cpan.org/Ticket/Display.html?id=21185

1362Imager 0.52 - 25 Jul 2006
1363===========
1364
1365This is primarily a feature release, but contains a fair few bug
1366fixes, new features:
1367
1368 - ability to read and write MS Windows ICO and CUR files
1369
1370 - you can now add file format plugins to support new file formats
1371
1372 - add POD coverage tests
1373
1374 - setcolors() and addcolors() now accept color names and so on
1375 instead of requiring Imager::Color objects.
1376 http://rt.cpan.org/Ticket/Display.html?id=20056
1377
1378 - flood_fill() can now fill to a specified border color instead of
1379 just to the area the same color as the seed.
1380 http://rt.cpan.org/Ticket/Display.html?id=19618
1381
1382
1383Bug fixes:
1384
1385 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1386 calculating the advance width.
1387 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1388
1389 - bounding_box for the T1 driver wasn't including leading and
1390 trailing spaces in the bounding box as the other drivers did, it also
1391 produced strange results for empty strings or strings containing only
1392 spaces
1393
1394 - when reading CMYK jpeg images they were being transferred to the
1395 image object as is, producing a four channel image. It only looked ok
1396 due to an old still unfixed Photoshop bug. We now convert from the
1397 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1398 http://rt.cpan.org/Ticket/Display.html?id=20416
1399
1400 - reading a CYMK TIFF would result in a 4 channel image, reading any
1401 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1402 result in an error.
1403 http://rt.cpan.org/Ticket/Display.html?id=20415
1404
1405 - added /usr/local/include to the default include search path, since
1406 we were already searching /usr/local/lib for libraries.
1407
1408And various minor fixes and documentation updates.
