TC
37
38 - add simple tests for the Imager::Test test_image generators
39

TC
40 - io_glue I/O buffering re-work:
41
42 - reorganize io_glue to do it's own buffering by default
43
44 - the unbuffered functions are available as i_io_raw_read() (or
45 raw_read() from perl) etc but are not recommended for typical
46 use.
47
48 - use the new i_io_peekn() when checking for file magic to avoid
49 seek, allowing Imager to detect the file type and read the file
50 from an unseekable stream (for formats that don't use random
51 access)
52
53 - added several new I/O layer API functions.
54
55 - fix the TGA performance problem, most noticably on Win32
56 https://rt.cpan.org/Ticket/Display.html?id=70037
57
58 - TIFF now uses wrapper functions of the correct types to avoid casts
59 https://rt.cpan.org/Ticket/Display.html?id=69912
60
61 - the callback IO object did its own buffering, controlled by the
62 maxbuffer parameter supplied to the read() and write() methods.
63 This buffering has been removed, to avoid redundancy with the
64 common io_glue buffering. This also avoids a bug in that code
65 which could rarely pass a zero length to the read callback and
66 then panic about the result.
67
68 - the callback IO object now tests the result of calling the close
69 callback, which should return true for success.
70
71 - the PNM reader did its own buffering. This buffering has been
72 removed to avoid redundancy with the common io_glue buffering.
73
74 - previously the read handlers for fd and callback I/O layers would
75 call the underlying interface (POSIX read or your supplied callback)
76 until it filled the buffer. It now only makes one call.
77
78 - added public constructors for I/O layer objects (see Imager::IO)
79
80 - all core file handlers now use the i_io_foo() wrappers to gain
81 access to buffered I/O rather than calling the I/O layer
82 callbacks directly.
83
84 - all core file handlers now check for error on close.
85
86 - Backward compatibility: if you hava custom file handlers, you can
87 use i_io_write() etc since they're available as macros in older
88 versions of Imager.
89
90 - eliminate the final remnants of io_glue_commit_types().
91
92 - bump IMAGER_API_VERSION, since the above may break assumptions.
93
94 - removed the long unused i_gen_reader() and i_gen_writer() utility
95 functions.

98===========
99
0c647c9a
TC
100The main changes in the release versus 0.84 are:
101
102 - on 64-bit systems, 64-bit types are consistently used for image
103 dimensions and co-ordinated, and for memory block sizes.
104
105 - handle IFD loops in TIFF files correctly. Previously this would
106 lead to an infinite loop.
107
6ad7e4bc
TC
108Bug fixes:

117
118Bug fixes:
119
120 - the image file limits set by set_file_limits() weren't being
121 checked when reading TIFF files.

123
5970bd39
TC
124 - Provide more information about file format module load errors on a
125 failed image file read() or write().
126 https://rt.cpan.org/Ticket/Display.html?id=69194
127
4ce3551c
TC
128 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
129 through TIFF images, since it checks for IFD loops.
130 https://rt.cpan.org/Ticket/Display.html?id=69914
131
a16bca6d
TC
132 - don't leak memory when out of range palette indexes are supplied to
133 setscanline().
134 https://rt.cpan.org/Ticket/Display.html?id=69242
135
136 - require a later version of CPAN::Meta to ensure JSON::PP and
137 CPAN::Meta::YAML are available.
138 https://rt.cpan.org/Ticket/Display.html?id=69008
139

140 - hoist the per-line calculations for the flines implementations, and

143
86c8d19a

155Imager 0.84_01 - 8 Aug 2011
156==============
157
158Development release as a sanity check for the types re-work.
8d14daab
TC
159
160Massive types re-work:
161
162 - the type used internally for pixel co-ordinates and image sizes is
163 now 64-bit on 64-bit platforms (at least sane ones).
164
165 - size_t is now used consistently for memory block sizes.
166
167 - since this changes the binary interface, the Imager API version has
168 been incremented. Any module that uses the API will need to be
169 rebuilt. In most cases that will be enough, but calls to any APIs
170 that take a pointer to image sizes may need source changes.
171
172 - you should be able to create very large images on 64-bit systems,
173 if you have enough memory. Successfully created a 32768 x 49192 x
174 3 channel image, filled with a tiled image and scaled it. The
175 unscaled image was also successfully saved to a JPEG.
176
177 - check the image size before attempting to write BMP, GIF, JPEG,
178 PNG, SGI, TGA, TIFF images.
179
180 - correctly handle reading TGA images over 32767 pixels wide or tall.
181
182Incidental changes:
183
184 - the gif_left and gif_top tags are now clamped to non-negative
185 values when writing a GIF image.
186
187 - removed dead callback read/write code
188
189The default maximum memory size when reading files is now 1G.

195 old, old perl.
196

216 - convert colors to grayscale if the supplied (or generated) palette
217 contains only grays when performing error diffusion color
218 translation.
219 https://rt.cpan.org/Ticket/Display.html?id=68508
220
59c150a4
TC
221 - writing a paletted image to GIF wouldn't always use the colors
222 supplied (or generated, eg. via make_colors => "mono"), which was
223 confusing at best.
224 https://rt.cpan.org/Ticket/Display.html?id=67912
225
5b480b14
TC
226 - replace (imager|tony)@imager.perl.org in the doc, since I don't

250 - compose() with the target, source or mask position off the top or
251 left of the target image didn't clip the source image correctly.

253
254 - compose() now returns a useful error message on a non-positive
255 opacity.
256

TC
261===========
262
263Bug fixes:
264
265 - eliminate calls to i_has_format() from the test suite, since it's
266 no longer a useful way to check for file format support. Eliminate
267 i_has_format() from the functions exposed via XS.
268 https://rt.cpan.org/Ticket/Display.html?id=65863
269
7540f84a
TC
270 - eliminate calls to note(), which isn't in the (very old) version of
271 Test::More we have as a pre-requisite. note() is modern enough
272 that I don't feel a need to require a Test::More upgrade for it.
273 https://rt.cpan.org/Ticket/Display.html?id=65864
274

285 downgrade the version in this file.
286 https://rt.cpan.org/Ticket/Display.html?id=66250
287
288 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
289 that option for the directories that would normally go in
290 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

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

1217Imager 0.55 - 16 Dec 2006
1218===========
1219
1220This is primarily a bug fix release.
1221
1222Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1223
1224There is one new feature:
1225
1226 - the Win32 font driver now supports UTF8 (RT 22166)
1227 http://www.cpanforum.com/threads/3276
1228 http://rt.cpan.org/Ticket/Display.html?id=22166
1229
1230Several bugs were fixed:
1231
1232 - the string() method would not output the string "0"
1233 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1234
1235 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1236 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1237
1238 - the gif_disposal and gif_user_input tags weren't being read from
1239 the file correctly
1240 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1241
1242 - gif.c was failing to build under MSVC
1243 http://rt.cpan.org/Ticket/Display.html?id=23922
1244
1245 - in some cases strings passed to the string() method were treated as
1246 terminated by NUL (chr 0)
1247 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1248
1249 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1250 that's the default build name for zlib on Win32.
1251 http://rt.cpan.org/Ticket/Display.html?id=23064
1252
1253 - search $Config{incpath} for headers too, which we should have been
1254 doing all along.
1255
1256Win32 font driver fixes:
1257
1258 - the global descent value from bounding box was the wrong sign
1259 http://www.cpanforum.com/threads/3276
1260
1261 - if the first or last glyph overflowed the left or right side of the
1262 advance width they would be clipped
1263
1264
1265Imager 0.54 - 14 Sep 2006
1266===========
1267
1268This is primarily a feature release:
1269
1270 - a new qtype value 'mixing' has been added to the scale()
1271 method. This is faster than 'normal', slower than 'preview'. This
1272 is based on the method used by pnmscale, and seems to produce less
1273 blurry results than normal.
1274 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1275
1276 - the rubthrough() method can now render onto images with an alpha
1277 channel.
1278 http://rt.cpan.org/Ticket/Display.html?id=20678
1279
1280 - the read_multi() method now falls back to calling doing a single
1281 image read via the read() method and write_multi() will now fall
1282 back to calling write() if a single image is supplied. This means
1283 you can simply call the read_multi() or write_multi() functions
1284 without having to check if the type is formatted by that method.
1285 http://rt.cpan.org/Ticket/Display.html?id=19457
1286 http://rt.cpan.org/Ticket/Display.html?id=19458
1287
1288 - the GIF loop extension can now be written. If you don't have
1289 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1290 should upgrade.
1291 http://rt.cpan.org/Ticket/Display.html?id=21185
1292
1293 - getscanline() and setscanline() can now read/write palette index
1294 based data from/to the image for paletted images, by setting type to
1295 'index'.
1296 http://rt.cpan.org/Ticket/Display.html?id=20338
1297
1298 - we no longer hassle you to disable GIF support
1299 http://rt.cpan.org/Ticket/Display.html?id=20687
1300
1301 - minor documentation fixes
1302
1303
1304Imager 0.53 - 26 Jul 2006
1305===========
1306
1307This is a bugfix release.
1308
1309Some test code was left in a code path not covered by the test
1310suite. A test was added to cover this code path and the test code was
1311removed.

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