TC
3 - describe how to build libgif etc on OS X in such a way as to be
4 compatible with a fat binary perl (such as the system perl), in
5 README.

TC
14 - note that the generator of the apparently non-DFSG-free postscript
15 in MMOne.pfb is a Debian package.
16
02323e69
TC
17 - setsamples() is now a true complement to getsamples() - it can
18 write 8-bit or floating point samples from a scalar or array
19 reference. This adds i_psamp() and i_psampf() to the C level API.
20
21 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
22 changed to make better use of the typemap, but these aren't part of
23 the perl level API anyway. There were no changes to the C level
24 interfaces to these functions.

34
5091168a
TC
35 - Win32 text output is now done in normal combine mode, the alpha
36 component of the color is now significant.

63 identify the file type match reality.
64 https://rt.cpan.org/Ticket/Display.html?id=72475
65
66 - read() now uses $FORMATGUESS if it can't determine the file type
67 based on the file header, to match read_multi().
68
69 - re-work and add tests for def_guess_type(). def_guess_type() no
70 longer returns any random file extension as the file type.
71

83 writing to a 1 or 3 channel image the second or fourth channel of
84 the source color was being ignored, it is now significant.

117
954ac5d1
TC
118 - depend on Scalar::Util, since we use it and older perls don't have
119 it.
120
5efba0c6
TC
121 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
122 to synthesize it from overloaded "".
123
73e3ff55
TC
124 - use T1_StrError() for error messages on modern libt1
125 https://rt.cpan.org/Ticket/Display.html?id=69879
126
127 - actually load the font rather than just adding it to the catalog on
128 creation.
129
130 - Imager::Font->new now produces better error messages for the T1
131 engine.
132
6e938c74
TC
133 - the font has_chars() method now returns perl's true and false
134 values in list context rather than integers, which should be more
135 efficient.
136 https://rt.cpan.org/Ticket/Display.html?id=69158
137
b934971a
TC
138 - the btm data structure used by the flood_fill code is now

81409c5e
TC
148 - make the APIRef synopsis ordering consistent, older versions of
149 perl could order it differently.
150 https://rt.cpan.org/Ticket/Display.html?id=71675
151
336ce474
TC
152 - we rely on Config.pm's d_vsnprintf as to whether we use
153 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
154 though it only has _ prefixed versions of these. Define our own
155 prefixed names on Win32.
156 https://rt.cpan.org/Ticket/Display.html?id=71642

31be6e9a 164Imager 0.85_01 - 10 Oct 2011
6d5c85a2 165==============
a7e32beb
TC
166
167 - add simple tests for the Imager::Test test_image generators
168
6d5c85a2
TC
169 - io_glue I/O buffering re-work:
170
171 - reorganize io_glue to do it's own buffering by default
172
173 - the unbuffered functions are available as i_io_raw_read() (or
174 raw_read() from perl) etc but are not recommended for typical
175 use.
176
177 - use the new i_io_peekn() when checking for file magic to avoid
178 seek, allowing Imager to detect the file type and read the file
179 from an unseekable stream (for formats that don't use random
180 access)
181
182 - added several new I/O layer API functions.
183
184 - fix the TGA performance problem, most noticably on Win32
185 https://rt.cpan.org/Ticket/Display.html?id=70037
186
187 - TIFF now uses wrapper functions of the correct types to avoid casts
188 https://rt.cpan.org/Ticket/Display.html?id=69912
189
190 - the callback IO object did its own buffering, controlled by the
191 maxbuffer parameter supplied to the read() and write() methods.
192 This buffering has been removed, to avoid redundancy with the
193 common io_glue buffering. This also avoids a bug in that code
194 which could rarely pass a zero length to the read callback and
195 then panic about the result.
196
197 - the callback IO object now tests the result of calling the close
198 callback, which should return true for success.
199
200 - the PNM reader did its own buffering. This buffering has been
201 removed to avoid redundancy with the common io_glue buffering.
202
203 - previously the read handlers for fd and callback I/O layers would
204 call the underlying interface (POSIX read or your supplied callback)
205 until it filled the buffer. It now only makes one call.
206
207 - added public constructors for I/O layer objects (see Imager::IO)
208
209 - all core file handlers now use the i_io_foo() wrappers to gain
210 access to buffered I/O rather than calling the I/O layer
211 callbacks directly.
212
213 - all core file handlers now check for error on close.
214
215 - Backward compatibility: if you hava custom file handlers, you can
216 use i_io_write() etc since they're available as macros in older
217 versions of Imager.
218
219 - eliminate the final remnants of io_glue_commit_types().
220
221 - bump IMAGER_API_VERSION, since the above may break assumptions.
222
223 - removed the long unused i_gen_reader() and i_gen_writer() utility
224 functions.

6ad7e4bc
TC
227===========
228
0c647c9a
TC
229The main changes in the release versus 0.84 are:
230
231 - on 64-bit systems, 64-bit types are consistently used for image
232 dimensions and co-ordinated, and for memory block sizes.
233
234 - handle IFD loops in TIFF files correctly. Previously this would
235 lead to an infinite loop.
236
6ad7e4bc
TC
237Bug fixes:
238
239 - fix the link in the getheight() entry in the method index

244Development release, this will become 0.85 if CPAN testers is
245favourable.
6b7197d0
TC
246
247Bug fixes:
248
249 - the image file limits set by set_file_limits() weren't being
250 checked when reading TIFF files.
251 https://rt.cpan.org/Ticket/Display.html?id=69915
252
5970bd39
TC
253 - Provide more information about file format module load errors on a
254 failed image file read() or write().
255 https://rt.cpan.org/Ticket/Display.html?id=69194
256
4ce3551c
TC
257 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
258 through TIFF images, since it checks for IFD loops.
259 https://rt.cpan.org/Ticket/Display.html?id=69914
260
a16bca6d
TC
261 - don't leak memory when out of range palette indexes are supplied to
262 setscanline().
263 https://rt.cpan.org/Ticket/Display.html?id=69242
264
265 - require a later version of CPAN::Meta to ensure JSON::PP and
266 CPAN::Meta::YAML are available.
267 https://rt.cpan.org/Ticket/Display.html?id=69008
268
ac575c5f
TC
269 - hoist the per-line calculations for the flines implementations, and
270 modernize the tests a bit.
271 https://rt.cpan.org/Ticket/Display.html?id=70126
272
86c8d19a
TC
273 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
274 them when available.
275 https://rt.cpan.org/Ticket/Display.html?id=69147
276
a3fd7df7
TC
277 - if t1lib failed to reinitialize it would be left as marked

284Imager 0.84_01 - 8 Aug 2011
285==============
286
287Development release as a sanity check for the types re-work.
8d14daab
TC
288
289Massive types re-work:
290
291 - the type used internally for pixel co-ordinates and image sizes is
292 now 64-bit on 64-bit platforms (at least sane ones).
293
294 - size_t is now used consistently for memory block sizes.
295
296 - since this changes the binary interface, the Imager API version has
297 been incremented. Any module that uses the API will need to be
298 rebuilt. In most cases that will be enough, but calls to any APIs
299 that take a pointer to image sizes may need source changes.
300
301 - you should be able to create very large images on 64-bit systems,
302 if you have enough memory. Successfully created a 32768 x 49192 x
303 3 channel image, filled with a tiled image and scaled it. The
304 unscaled image was also successfully saved to a JPEG.
305
306 - check the image size before attempting to write BMP, GIF, JPEG,
307 PNG, SGI, TGA, TIFF images.
308
309 - correctly handle reading TGA images over 32767 pixels wide or tall.
310
311Incidental changes:
312
313 - the gif_left and gif_top tags are now clamped to non-negative
314 values when writing a GIF image.
315
316 - removed dead callback read/write code
317
318The default maximum memory size when reading files is now 1G.

b1e66a82
TC
321===========
322
323 - Imager no longer inherits from Exporter (unless you're running an
324 old, old perl.
325
92e9df65
TC
326 - Imager can now write progressive JPEGs (it could always read them).

TC
329Bug fixes:

344
6d068d36
TC
345 - convert colors to grayscale if the supplied (or generated) palette
346 contains only grays when performing error diffusion color
347 translation.
348 https://rt.cpan.org/Ticket/Display.html?id=68508
349
59c150a4
TC
350 - writing a paletted image to GIF wouldn't always use the colors
351 supplied (or generated, eg. via make_colors => "mono"), which was
352 confusing at best.
353 https://rt.cpan.org/Ticket/Display.html?id=67912
354
5b480b14
TC
355 - replace (imager|tony)@imager.perl.org in the doc, since I don't

378
618a3282
TC
379 - compose() with the target, source or mask position off the top or
380 left of the target image didn't clip the source image correctly.
381 https://rt.cpan.org/Ticket/Display.html?id=67220
382
383 - compose() now returns a useful error message on a non-positive
384 opacity.
385
386 - compose.im now at 100% test coverage. (As opposed to, umm, much,
387 much less.)

c1d16c8f 389Imager 0.82 - 14 Mar 2011
2368cfec
TC
390===========
391
392Bug fixes:
393
394 - eliminate calls to i_has_format() from the test suite, since it's
395 no longer a useful way to check for file format support. Eliminate
396 i_has_format() from the functions exposed via XS.
397 https://rt.cpan.org/Ticket/Display.html?id=65863
398
7540f84a
TC
399 - eliminate calls to note(), which isn't in the (very old) version of
400 Test::More we have as a pre-requisite. note() is modern enough
401 that I don't feel a need to require a Test::More upgrade for it.
402 https://rt.cpan.org/Ticket/Display.html?id=65864
403
81984f30

413 - increase the version of Imager::Font::Type1 so that upgrades don't
414 downgrade the version in this file.
415 https://rt.cpan.org/Ticket/Display.html?id=66250
416
417 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
418 that option for the directories that would normally go in
419 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

447 matrix with specified co-efficients. You can now multiple an
448 Imager::Matrix2d object by a 9 element array ref or a number.

928 - Possible security issue: The floating point sample path for image
929 based fills had a buffer overflow. This would overwrite the end of
930 a malloc()ed buffer with double precision floats.

934 - check that the result of fileno($fh) is defined rather than simply
935 true when read() or write() is supplied with an fh parameter.
936 http://rt.cpan.org/Ticket/Display.html?id=35139
937
938 - i_scale_axis() wasn't checking the result of i_img_new_ch()
939 resulting in a SIGSEGV when attempting to scale an image to a size
940 too large to fit in memory. This is a NULL pointer access issue,
941 not a buffer overflow.
942 Added a check for the failure.
943 scale_calculate() (and hence scale()) will now fail if any of the
944 scale size parameters are a reference.

956This release primarily contains changes to improve ease of use -
957rather than you having to convert images to the appropriate number of
958channels, Imager handles it internally. How to handle drawing colors
959and the default combine mode is a thornier problem left for some other
960release.

TC
965 - moved the imtoc.perl code into Imager::Preprocess
966
967 - paste() and rubthrough() now adapt the source image data to the
968 destination, so you can now safely paste/rubthrough from greyscale
969 images to color images or back, or from alpha channel images to
970 noalpha channels or back.
971 https://rt.cpan.org/Ticket/Display.html?id=30908
972
973 - rubthrough() now falls back to pasting when the source doesn't have
974 an alpha channel. This effectively treats the source as having a
975 max alpha channel, the right thing to do.
976 http://rt.cpan.org/Ticket/Display.html?id=29944
977
978 - re-worked most of the area filling code to use a common set of
979 functions when filling.
980 Corrected normal combine mode.
981 Rewrote most of the combine modes to match the way the SVG draft
982 defines them with respect to a translucent source and destination.
983 Added tests for translucent source and destination.
984 Added tests to check 8-bit/sample and double/sample combines work
985 similarly.

1023
1024 - handling of the left-over bit for 16-bit/pixel TGA images has been
1025 changed to match the behaviour of the GIMP. Previously the bit
1026 being set was treated as an opaque pixel, but one user reported a
1027 problem with loading such an image. I haven't been able to find any
1028 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1029 I'll match it's behaviour. See issue 114913 in the GIMP's
1030 bugzilla.

1040 - the old dynaload code used Mach API functions to load dynamic
1041 libraries on Mac OS X. These APIs have been deprecated in OS X
1042 10.5 and were causing some build problems.

1044 will need version 10.3 or later of OS X.

1330
1331 - previously, reading ASCII PBM files required spaces between samples,
1332 even though the format doesn't require that

1334 - improved documentation of the unsharpmask filter (I hope)
1335 http://rt.cpan.org/Ticket/Display.html?id=25531
1336
1337 - force flushing of the output from i_tt_dump_names() and test output
1338 in t/t35ttfont.t to prevent output from being mixed up.
1339 https://rt.cpan.org/Ticket/Display.html?id=24859

1341 - rewrite a conditional expression as an if() to hopefully work around
1342 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.

1348Imager 0.55 - 16 Dec 2006
1349===========
1350
1351This is primarily a bug fix release.
1352
1353Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1354
1355There is one new feature:
1356
1357 - the Win32 font driver now supports UTF8 (RT 22166)
1358 http://www.cpanforum.com/threads/3276
1359 http://rt.cpan.org/Ticket/Display.html?id=22166
1360
1361Several bugs were fixed:
1362
1363 - the string() method would not output the string "0"
1364 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1365
1366 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1367 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1368
1369 - the gif_disposal and gif_user_input tags weren't being read from
1370 the file correctly
1371 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1372
1373 - gif.c was failing to build under MSVC
1374 http://rt.cpan.org/Ticket/Display.html?id=23922
1375
1376 - in some cases strings passed to the string() method were treated as
1377 terminated by NUL (chr 0)
1378 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1379
1380 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1381 that's the default build name for zlib on Win32.
1382 http://rt.cpan.org/Ticket/Display.html?id=23064
1383
1384 - search $Config{incpath} for headers too, which we should have been
1385 doing all along.
1386
1387Win32 font driver fixes:
1388
1389 - the global descent value from bounding box was the wrong sign
1390 http://www.cpanforum.com/threads/3276
1391
1392 - if the first or last glyph overflowed the left or right side of the
1393 advance width they would be clipped
1394
1395
1396Imager 0.54 - 14 Sep 2006
1397===========
1398
1399This is primarily a feature release:
1400
1401 - a new qtype value 'mixing' has been added to the scale()
1402 method. This is faster than 'normal', slower than 'preview'. This
1403 is based on the method used by pnmscale, and seems to produce less
1404 blurry results than normal.
1405 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1406
1407 - the rubthrough() method can now render onto images with an alpha
1408 channel.
1409 http://rt.cpan.org/Ticket/Display.html?id=20678
1410
1411 - the read_multi() method now falls back to calling doing a single
1412 image read via the read() method and write_multi() will now fall
1413 back to calling write() if a single image is supplied. This means
1414 you can simply call the read_multi() or write_multi() functions
1415 without having to check if the type is formatted by that method.
1416 http://rt.cpan.org/Ticket/Display.html?id=19457
1417 http://rt.cpan.org/Ticket/Display.html?id=19458
1418
1419 - the GIF loop extension can now be written. If you don't have
1420 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1421 should upgrade.
1422 http://rt.cpan.org/Ticket/Display.html?id=21185
1423
1424 - getscanline() and setscanline() can now read/write palette index
1425 based data from/to the image for paletted images, by setting type to
1426 'index'.
1427 http://rt.cpan.org/Ticket/Display.html?id=20338
1428
1429 - we no longer hassle you to disable GIF support
1430 http://rt.cpan.org/Ticket/Display.html?id=20687
1431
1432 - minor documentation fixes
1433
1434
1435Imager 0.53 - 26 Jul 2006
1436===========
1437
1438This is a bugfix release.
1439
1440Some test code was left in a code path not covered by the test
1441suite. A test was added to cover this code path and the test code was
1442removed.
1443http://rt.cpan.org/Public/Bug/Display.html?id=20705
1444
1445
1446Imager 0.52 - 25 Jul 2006
1447===========
1448
1449This is primarily a feature release, but contains a fair few bug
1450fixes, new features:
1451
1452 - ability to read and write MS Windows ICO and CUR files
1453
1454 - you can now add file format plugins to support new file formats
1455
1456 - add POD coverage tests
1457
1458 - setcolors() and addcolors() now accept color names and so on
1459 instead of requiring Imager::Color objects.
1460 http://rt.cpan.org/Ticket/Display.html?id=20056
1461
1462 - flood_fill() can now fill to a specified border color instead of
1463 just to the area the same color as the seed.
1464 http://rt.cpan.org/Ticket/Display.html?id=19618
1465
1466
1467Bug fixes:
1468
1469 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1470 calculating the advance width.
1471 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1472
1473 - bounding_box for the T1 driver wasn't including leading and
1474 trailing spaces in the bounding box as the other drivers did, it also
1475 produced strange results for empty strings or strings containing only
1476 spaces
1477
1478 - when reading CMYK jpeg images they were being transferred to the
1479 image object as is, producing a four channel image. It only looked ok
1480 due to an old still unfixed Photoshop bug. We now convert from the
1481 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1482 http://rt.cpan.org/Ticket/Display.html?id=20416
1483
1484 - reading a CYMK TIFF would result in a 4 channel image, reading any
1485 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1486 result in an error.
1487 http://rt.cpan.org/Ticket/Display.html?id=20415
1488
1489 - added /usr/local/include to the default include search path, since
1490 we were already searching /usr/local/lib for libraries.
1491
1492And various minor fixes and documentation updates.
1493
1494
1495Imager 0.51 - 23 Apr 2006

1499 a crash
1500 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1501
1502 - fix mis-processing of the src_maxx and src_maxy parameters of the
1503 paste() method
1504 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1505
1506 - fix a problem in Imager's "smart" handling of the color parameter
1507 to various methods.
1508 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1509
1510
1511Imager 0.50 - 29 Mar 2006
1512===========
1513
1514 - CRITICAL: fixes a segmentation fault from attempting to write a 2
1515 or 4 channel image to jpeg or a 2 channel image to tga where the
1516 output is an in-memeory buffer.
1517 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1518
1519 - fixes an incorrect pointer parameter in the PNG code
1520 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1521
1522 - skip Inline::C tests when building in a directory with spaces
1523 http://rt.cpan.org/Public/Bug/Display.html?id=18049
