29 - depend on Scalar::Util, since we use it and older perls don't have
30 it.
31
5efba0c6

35 - use T1_StrError() for error messages on modern libt1
36 https://rt.cpan.org/Ticket/Display.html?id=69879

39 creation.
40
41 - Imager::Font->new now produces better error messages for the T1
42 engine.
43
6e938c74
TC
44 - the font has_chars() method now returns perl's true and false
45 values in list context rather than integers, which should be more
46 efficient.

336ce474
TC
63 - we rely on Config.pm's d_vsnprintf as to whether we use
64 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
65 though it only has _ prefixed versions of these. Define our own
66 prefixed names on Win32.

31be6e9a 75Imager 0.85_01 - 10 Oct 2011
6d5c85a2 76==============
a7e32beb
TC
77
78 - add simple tests for the Imager::Test test_image generators
79
6d5c85a2
TC
80 - io_glue I/O buffering re-work:
81
82 - reorganize io_glue to do it's own buffering by default
83
84 - the unbuffered functions are available as i_io_raw_read() (or
85 raw_read() from perl) etc but are not recommended for typical
86 use.
87
88 - use the new i_io_peekn() when checking for file magic to avoid
89 seek, allowing Imager to detect the file type and read the file
90 from an unseekable stream (for formats that don't use random
91 access)
92
93 - added several new I/O layer API functions.
94
95 - fix the TGA performance problem, most noticably on Win32
96 https://rt.cpan.org/Ticket/Display.html?id=70037
97
98 - TIFF now uses wrapper functions of the correct types to avoid casts
99 https://rt.cpan.org/Ticket/Display.html?id=69912
100
101 - the callback IO object did its own buffering, controlled by the
102 maxbuffer parameter supplied to the read() and write() methods.
103 This buffering has been removed, to avoid redundancy with the
104 common io_glue buffering. This also avoids a bug in that code
105 which could rarely pass a zero length to the read callback and
106 then panic about the result.
107
108 - the callback IO object now tests the result of calling the close
109 callback, which should return true for success.
110
111 - the PNM reader did its own buffering. This buffering has been
112 removed to avoid redundancy with the common io_glue buffering.
113
114 - previously the read handlers for fd and callback I/O layers would
115 call the underlying interface (POSIX read or your supplied callback)
116 until it filled the buffer. It now only makes one call.
117
118 - added public constructors for I/O layer objects (see Imager::IO)
119
120 - all core file handlers now use the i_io_foo() wrappers to gain
121 access to buffered I/O rather than calling the I/O layer
122 callbacks directly.
123
124 - all core file handlers now check for error on close.
125
126 - Backward compatibility: if you hava custom file handlers, you can
127 use i_io_write() etc since they're available as macros in older
128 versions of Imager.
129
130 - eliminate the final remnants of io_glue_commit_types().
131
132 - bump IMAGER_API_VERSION, since the above may break assumptions.
133
134 - removed the long unused i_gen_reader() and i_gen_writer() utility
135 functions.

6ad7e4bc
TC
138===========
139
0c647c9a
TC
140The main changes in the release versus 0.84 are:
141
142 - on 64-bit systems, 64-bit types are consistently used for image
143 dimensions and co-ordinated, and for memory block sizes.
144
145 - handle IFD loops in TIFF files correctly. Previously this would
146 lead to an infinite loop.
147
6ad7e4bc
TC
148Bug fixes:
149
150 - fix the link in the getheight() entry in the method index

156favourable.
6b7197d0
TC
157
158Bug fixes:
159
160 - the image file limits set by set_file_limits() weren't being
161 checked when reading TIFF files.
162 https://rt.cpan.org/Ticket/Display.html?id=69915
163
5970bd39
TC
164 - Provide more information about file format module load errors on a
165 failed image file read() or write().
166 https://rt.cpan.org/Ticket/Display.html?id=69194
167
4ce3551c
TC
168 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
169 through TIFF images, since it checks for IFD loops.
170 https://rt.cpan.org/Ticket/Display.html?id=69914
171
a16bca6d
TC
172 - don't leak memory when out of range palette indexes are supplied to
173 setscanline().
174 https://rt.cpan.org/Ticket/Display.html?id=69242
175
176 - require a later version of CPAN::Meta to ensure JSON::PP and
177 CPAN::Meta::YAML are available.
178 https://rt.cpan.org/Ticket/Display.html?id=69008
179
ac575c5f
TC
180 - hoist the per-line calculations for the flines implementations, and
181 modernize the tests a bit.
182 https://rt.cpan.org/Ticket/Display.html?id=70126
183
86c8d19a
TC
184 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
185 them when available.

187
a3fd7df7
TC
188 - if t1lib failed to reinitialize it would be left as marked

195Imager 0.84_01 - 8 Aug 2011
196==============
197
198Development release as a sanity check for the types re-work.
8d14daab
TC
199
200Massive types re-work:
201
202 - the type used internally for pixel co-ordinates and image sizes is
203 now 64-bit on 64-bit platforms (at least sane ones).
204
205 - size_t is now used consistently for memory block sizes.
206
207 - since this changes the binary interface, the Imager API version has
208 been incremented. Any module that uses the API will need to be
209 rebuilt. In most cases that will be enough, but calls to any APIs
210 that take a pointer to image sizes may need source changes.
211
212 - you should be able to create very large images on 64-bit systems,
213 if you have enough memory. Successfully created a 32768 x 49192 x
214 3 channel image, filled with a tiled image and scaled it. The
215 unscaled image was also successfully saved to a JPEG.
216
217 - check the image size before attempting to write BMP, GIF, JPEG,
218 PNG, SGI, TGA, TIFF images.
219
220 - correctly handle reading TGA images over 32767 pixels wide or tall.
221
222Incidental changes:
223
224 - the gif_left and gif_top tags are now clamped to non-negative
225 values when writing a GIF image.
226
227 - removed dead callback read/write code
228
229The default maximum memory size when reading files is now 1G.

TC
232===========
233
234 - Imager no longer inherits from Exporter (unless you're running an
235 old, old perl.
236
92e9df65
TC
237 - Imager can now write progressive JPEGs (it could always read them).

255
6d068d36
TC
256 - convert colors to grayscale if the supplied (or generated) palette
257 contains only grays when performing error diffusion color
258 translation.
259 https://rt.cpan.org/Ticket/Display.html?id=68508
260
59c150a4
TC
261 - writing a paletted image to GIF wouldn't always use the colors
262 supplied (or generated, eg. via make_colors => "mono"), which was
263 confusing at best.
264 https://rt.cpan.org/Ticket/Display.html?id=67912
265
5b480b14
TC
266 - replace (imager|tony)@imager.perl.org in the doc, since I don't

287 Win32. Thanks to kmx for the report and fix.
288 https://rt.cpan.org/Ticket/Display.html?id=67963
289
618a3282
TC
290 - compose() with the target, source or mask position off the top or
291 left of the target image didn't clip the source image correctly.
292 https://rt.cpan.org/Ticket/Display.html?id=67220
293
294 - compose() now returns a useful error message on a non-positive
295 opacity.
296
297 - compose.im now at 100% test coverage. (As opposed to, umm, much,
298 much less.)

c1d16c8f 300Imager 0.82 - 14 Mar 2011
2368cfec
TC
301===========
302
303Bug fixes:
304
305 - eliminate calls to i_has_format() from the test suite, since it's
306 no longer a useful way to check for file format support. Eliminate
307 i_has_format() from the functions exposed via XS.
308 https://rt.cpan.org/Ticket/Display.html?id=65863
309
7540f84a
TC
310 - eliminate calls to note(), which isn't in the (very old) version of
311 Test::More we have as a pre-requisite. note() is modern enough
312 that I don't feel a need to require a Test::More upgrade for it.
313 https://rt.cpan.org/Ticket/Display.html?id=65864
314
81984f30

324 - increase the version of Imager::Font::Type1 so that upgrades don't
325 downgrade the version in this file.
326 https://rt.cpan.org/Ticket/Display.html?id=66250
327
328 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
329 that option for the directories that would normally go in
330 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

407 - the convert() method now optimizes the case where all output
408 channels are either 0, sourced from a single input channel or 1.
409 This significantly speeds up presets like "addalpha", "green".

881
882 - rubthrough() now falls back to pasting when the source doesn't have
883 an alpha channel. This effectively treats the source as having a
884 max alpha channel, the right thing to do.

918 - mixing qtype scaling now sets all channels of a pixel to zero if
919 the pixel has zero coverage (zero alpha). This should produce more

930 - some TGA images weren't being detected correctly as TGA images
931 https://rt.cpan.org/Ticket/Display.html?id=32925
932
933 - handling of the left-over bit for 16-bit/pixel TGA images has been
934 changed to match the behaviour of the GIMP. Previously the bit
935 being set was treated as an opaque pixel, but one user reported a
936 problem with loading such an image. I haven't been able to find any
937 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
938 I'll match it's behaviour. See issue 114913 in the GIMP's
939 bugzilla.

949 - the old dynaload code used Mach API functions to load dynamic
950 libraries on Mac OS X. These APIs have been deprecated in OS X
951 10.5 and were causing some build problems.
952 So henceforth Imager uses the dlopen() family of functions, and you
953 will need version 10.3 or later of OS X.

1262Note: Test::More is now a pre-requisite for Imager and is no longer bundled.

1268 http://rt.cpan.org/Ticket/Display.html?id=22166

1272 - the string() method would not output the string "0"
1273 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1274
1275 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1276 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1277
1278 - the gif_disposal and gif_user_input tags weren't being read from
1279 the file correctly
1280 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1281
1282 - gif.c was failing to build under MSVC
1283 http://rt.cpan.org/Ticket/Display.html?id=23922
1284
1285 - in some cases strings passed to the string() method were treated as
1286 terminated by NUL (chr 0)
1287 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1288
1289 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1290 that's the default build name for zlib on Win32.
1291 http://rt.cpan.org/Ticket/Display.html?id=23064
1292
1293 - search $Config{incpath} for headers too, which we should have been
1294 doing all along.
1295
1296Win32 font driver fixes:
1297
1298 - the global descent value from bounding box was the wrong sign
1299 http://www.cpanforum.com/threads/3276
1300

1304
1305Imager 0.54 - 14 Sep 2006
1306===========
1307
1308This is primarily a feature release:
1309
1310 - a new qtype value 'mixing' has been added to the scale()
1311 method. This is faster than 'normal', slower than 'preview'. This
1312 is based on the method used by pnmscale, and seems to produce less
1313 blurry results than normal.
1314 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1315
1316 - the rubthrough() method can now render onto images with an alpha
1317 channel.
1318 http://rt.cpan.org/Ticket/Display.html?id=20678
1319
1320 - the read_multi() method now falls back to calling doing a single
1321 image read via the read() method and write_multi() will now fall
1322 back to calling write() if a single image is supplied. This means
1323 you can simply call the read_multi() or write_multi() functions
1324 without having to check if the type is formatted by that method.
1325 http://rt.cpan.org/Ticket/Display.html?id=19457
1326 http://rt.cpan.org/Ticket/Display.html?id=19458
1327
1328 - the GIF loop extension can now be written. If you don't have
1329 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1330 should upgrade.
1331 http://rt.cpan.org/Ticket/Display.html?id=21185
1332
1333 - getscanline() and setscanline() can now read/write palette index
1334 based data from/to the image for paletted images, by setting type to
1335 'index'.
1336 http://rt.cpan.org/Ticket/Display.html?id=20338
1337
1338 - we no longer hassle you to disable GIF support
1339 http://rt.cpan.org/Ticket/Display.html?id=20687
1340
1341 - minor documentation fixes

1355Imager 0.52 - 25 Jul 2006
1356===========
1357
1358This is primarily a feature release, but contains a fair few bug
1359fixes, new features:
1360
1361 - ability to read and write MS Windows ICO and CUR files
1362
1363 - you can now add file format plugins to support new file formats
1364
1365 - add POD coverage tests
1366
1367 - setcolors() and addcolors() now accept color names and so on
1368 instead of requiring Imager::Color objects.
1369 http://rt.cpan.org/Ticket/Display.html?id=20056
1370
1371 - flood_fill() can now fill to a specified border color instead of
1372 just to the area the same color as the seed.
1373 http://rt.cpan.org/Ticket/Display.html?id=19618
1374
1375
1376Bug fixes:
1377
1378 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1379 calculating the advance width.
1380 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1381
1382 - bounding_box for the T1 driver wasn't including leading and
1383 trailing spaces in the bounding box as the other drivers did, it also
1384 produced strange results for empty strings or strings containing only
1385 spaces
1386
1387 - when reading CMYK jpeg images they were being transferred to the
1388 image object as is, producing a four channel image. It only looked ok
1389 due to an old still unfixed Photoshop bug. We now convert from the
1390 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1391 http://rt.cpan.org/Ticket/Display.html?id=20416
1392
1393 - reading a CYMK TIFF would result in a 4 channel image, reading any
1394 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1395 result in an error.
1396 http://rt.cpan.org/Ticket/Display.html?id=20415
1397
1398 - added /usr/local/include to the default include search path, since
1399 we were already searching /usr/local/lib for libraries.
1400
1401And various minor fixes and documentation updates.
