3Imager 0.90 - unreleased
4===========
5
6Bug fixes:
7
8 - Imager::Test::is_imaged() attempted to process an "epsilon"
9 parameter but the prototype didn't allow for the extra parameter.
10 Corrected the prototype.
11
29b38678
TC
12 - when downconverting samples (eg. from floating point to 8 bit)
13 Imager now rounds the sample value rather than attempting to
14 allocate input values over output values equally. The old
15 behaviour had the probably surprising effect of converting a
16 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
17 2.
18 This may result in slightly different 8 or 16-bit output images.
19
e2a86bac
TC
20 - BI_BITFIELD BMP images were handled incorrectly, both in
21 incorrectly calculating the space required for the masks and in
22 processing the image data itself.
23 https://rt.cpan.org/Ticket/Display.html?id=76736
24
25 - some odd width BMP BI_RLE4 images use run lengths that run one off
26 the edge of the image. Imager now allows this, discarding the
27 extra column.
28
29 - odd length RLE4 runs in BMP images were decoded incorrectly.
30
9d5ff8a6
TC
31Other changes:
32
33 - when reading or writing images via callbacks, the default callbacks
34 now push an error message indicating that a required callback was
35 called but not supplied.
36 https://rt.cpan.org/Ticket/Display.html?id=76782
37
38 - clarify which callbacks are required for reading and writing TIFF
39 images.
40
41 - improve logging for creation of callback I/O layers.

43Imager 0.89 - 18 Mar 2012
44===========
45
46Bug fixes:
47
93eab01e
TC
48 - getpixel(..., type => "float") and the API i_gpixf() have been
49 broken on paletted images since they were implemented.

52Other changes:

TC
54 - links in the METHOD INDEX now point at the method documentation
55 rather than the heading you can find them under.
56 https://rt.cpan.org/Ticket/Display.html?id=71495
57

TC
58 - Imager (and the bundled dynamic modules) no longer fallback to
59 using DynaLoader if loading via XSLoader fails.
60 For the bundled modules this could hide useful error messages.
61 https://rt.cpan.org/Ticket/Display.html?id=75560
62
335078fc
TC
63 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
64 buffer in the array of allocations, but just stores the filename
65 pointer and line number.

68Imager 0.88 - 22 Feb 2012
69===========
70
43bef43b
TC
71 - describe how to build libgif etc on OS X in such a way as to be
72 compatible with a fat binary perl (such as the system perl), in
73 README.
74 https://rt.cpan.org/Ticket/Display.html?id=73371
75
69675eef
TC
76 - update the change notes for 0.77_01 to indicate that libungif
77 support was removed.
78

TC
79 - add some other imaging modules to SEE ALSO
80 https://rt.cpan.org/Ticket/Display.html?id=73906
81
3b7f10da
TC
82 - note that the generator of the apparently non-DFSG-free postscript
83 in MMOne.pfb is a Debian package.
84
02323e69
TC
85 - setsamples() is now a true complement to getsamples() - it can
86 write 8-bit or floating point samples from a scalar or array
87 reference. This adds i_psamp() and i_psampf() to the C level API.
88
89 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
90 changed to make better use of the typemap, but these aren't part of
91 the perl level API anyway. There were no changes to the C level
92 interfaces to these functions.
93
2a27eeff
TC
94 - getpixel() and setpixel() now accept a mix of scalar and array
95 references for the x and y parameters, and unequal array lengths is
96 no longer an error.

107
5091168a
TC
108 - Win32 text output is now done in normal combine mode, the alpha
109 component of the color is now significant.

112 - remove long unused gif case from read()
113 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
114
7640e3bb
TC
115 - the getsamples() target parameter was being treated as a hashref
116 when it's meant to be an array reference.
117 https://rt.cpan.org/Ticket/Display.html?id=74882
118
2a27eeff
TC
119 - getpixel() and setpixel() now returns an empty list when invalid
120 parameters are supplied.
121 Invalid values for type now result in an error for getpixel().

TC
140 - make the error message from read() or read_multi() when they can't
141 identify the file type match reality.
142 https://rt.cpan.org/Ticket/Display.html?id=72475
143
144 - read() now uses $FORMATGUESS if it can't determine the file type
145 based on the file header, to match read_multi().
146
147 - re-work and add tests for def_guess_type(). def_guess_type() no
148 longer returns any random file extension as the file type.

a044f2c6
TC
160 - fix i_render_color() to properly draw in "normal" mode - ie. when
161 writing to a 1 or 3 channel image the second or fourth channel of
162 the source color was being ignored, it is now significant.

TC
194 - add extra ppport.h configuration to support older perls.
195
954ac5d1
TC
196 - depend on Scalar::Util, since we use it and older perls don't have
197 it.
198
5efba0c6
TC
199 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
200 to synthesize it from overloaded "".
201
73e3ff55
TC
202 - use T1_StrError() for error messages on modern libt1
203 https://rt.cpan.org/Ticket/Display.html?id=69879
204
205 - actually load the font rather than just adding it to the catalog on
206 creation.
207
208 - Imager::Font->new now produces better error messages for the T1
209 engine.
210
6e938c74
TC
211 - the font has_chars() method now returns perl's true and false
212 values in list context rather than integers, which should be more
213 efficient.
214 https://rt.cpan.org/Ticket/Display.html?id=69158
215

TC
216 - the btm data structure used by the flood_fill code is now

224 https://rt.cpan.org/Ticket/Display.html?id=68993
225
81409c5e
TC
226 - make the APIRef synopsis ordering consistent, older versions of
227 perl could order it differently.
228 https://rt.cpan.org/Ticket/Display.html?id=71675
229
336ce474
TC
230 - we rely on Config.pm's d_vsnprintf as to whether we use
231 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
232 though it only has _ prefixed versions of these. Define our own
233 prefixed names on Win32.

31be6e9a 242Imager 0.85_01 - 10 Oct 2011
6d5c85a2 243==============
a7e32beb
TC
244
245 - add simple tests for the Imager::Test test_image generators
246
6d5c85a2
TC
247 - io_glue I/O buffering re-work:
248
249 - reorganize io_glue to do it's own buffering by default
250
251 - the unbuffered functions are available as i_io_raw_read() (or
252 raw_read() from perl) etc but are not recommended for typical
253 use.
254
255 - use the new i_io_peekn() when checking for file magic to avoid
256 seek, allowing Imager to detect the file type and read the file
257 from an unseekable stream (for formats that don't use random
258 access)
259
260 - added several new I/O layer API functions.
261
262 - fix the TGA performance problem, most noticably on Win32
263 https://rt.cpan.org/Ticket/Display.html?id=70037
264
265 - TIFF now uses wrapper functions of the correct types to avoid casts
266 https://rt.cpan.org/Ticket/Display.html?id=69912
267
268 - the callback IO object did its own buffering, controlled by the
269 maxbuffer parameter supplied to the read() and write() methods.
270 This buffering has been removed, to avoid redundancy with the
271 common io_glue buffering. This also avoids a bug in that code
272 which could rarely pass a zero length to the read callback and
273 then panic about the result.
274
275 - the callback IO object now tests the result of calling the close
276 callback, which should return true for success.
277
278 - the PNM reader did its own buffering. This buffering has been
279 removed to avoid redundancy with the common io_glue buffering.
280
281 - previously the read handlers for fd and callback I/O layers would
282 call the underlying interface (POSIX read or your supplied callback)
283 until it filled the buffer. It now only makes one call.
284
285 - added public constructors for I/O layer objects (see Imager::IO)
286
287 - all core file handlers now use the i_io_foo() wrappers to gain
288 access to buffered I/O rather than calling the I/O layer
289 callbacks directly.
290
291 - all core file handlers now check for error on close.
292
293 - Backward compatibility: if you hava custom file handlers, you can
294 use i_io_write() etc since they're available as macros in older
295 versions of Imager.
296
297 - eliminate the final remnants of io_glue_commit_types().
298
299 - bump IMAGER_API_VERSION, since the above may break assumptions.
300
301 - removed the long unused i_gen_reader() and i_gen_writer() utility
302 functions.

6ad7e4bc
TC
305===========
306
0c647c9a
TC
307The main changes in the release versus 0.84 are:
308
309 - on 64-bit systems, 64-bit types are consistently used for image
310 dimensions and co-ordinated, and for memory block sizes.
311
312 - handle IFD loops in TIFF files correctly. Previously this would
313 lead to an infinite loop.
314
6ad7e4bc
TC
315Bug fixes:
316
317 - fix the link in the getheight() entry in the method index

334
4ce3551c
TC
335 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
336 through TIFF images, since it checks for IFD loops.
337 https://rt.cpan.org/Ticket/Display.html?id=69914
338
a16bca6d

339 - don't leak memory when out of range palette indexes are supplied to

342
343 - require a later version of CPAN::Meta to ensure JSON::PP and

362Imager 0.84_01 - 8 Aug 2011
363==============
364
365Development release as a sanity check for the types re-work.
8d14daab
TC
366
367Massive types re-work:
368
369 - the type used internally for pixel co-ordinates and image sizes is
370 now 64-bit on 64-bit platforms (at least sane ones).
371
372 - size_t is now used consistently for memory block sizes.
373
374 - since this changes the binary interface, the Imager API version has
375 been incremented. Any module that uses the API will need to be
376 rebuilt. In most cases that will be enough, but calls to any APIs
377 that take a pointer to image sizes may need source changes.
378
379 - you should be able to create very large images on 64-bit systems,
380 if you have enough memory. Successfully created a 32768 x 49192 x
381 3 channel image, filled with a tiled image and scaled it. The
382 unscaled image was also successfully saved to a JPEG.
383
384 - check the image size before attempting to write BMP, GIF, JPEG,
385 PNG, SGI, TGA, TIFF images.
386
387 - correctly handle reading TGA images over 32767 pixels wide or tall.
388
389Incidental changes:
390
391 - the gif_left and gif_top tags are now clamped to non-negative
392 values when writing a GIF image.
393
394 - removed dead callback read/write code
395
396The default maximum memory size when reading files is now 1G.

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

1034This release primarily contains changes to improve ease of use -
1035rather than you having to convert images to the appropriate number of
1036channels, Imager handles it internally. How to handle drawing colors
1037and the default combine mode is a thornier problem left for some other
1038release.

TC
1043 - moved the imtoc.perl code into Imager::Preprocess
1044
1045 - paste() and rubthrough() now adapt the source image data to the
1046 destination, so you can now safely paste/rubthrough from greyscale
1047 images to color images or back, or from alpha channel images to
1048 noalpha channels or back.
1049 https://rt.cpan.org/Ticket/Display.html?id=30908
1050
1051 - rubthrough() now falls back to pasting when the source doesn't have
1052 an alpha channel. This effectively treats the source as having a
1053 max alpha channel, the right thing to do.
1054 http://rt.cpan.org/Ticket/Display.html?id=29944
1055
1056 - re-worked most of the area filling code to use a common set of
1057 functions when filling.
1058 Corrected normal combine mode.
1059 Rewrote most of the combine modes to match the way the SVG draft
1060 defines them with respect to a translucent source and destination.
1061 Added tests for translucent source and destination.
1062 Added tests to check 8-bit/sample and double/sample combines work
1063 similarly.

1102 - handling of the left-over bit for 16-bit/pixel TGA images has been
1103 changed to match the behaviour of the GIMP. Previously the bit
1104 being set was treated as an opaque pixel, but one user reported a
1105 problem with loading such an image. I haven't been able to find any
1106 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1107 I'll match it's behaviour. See issue 114913 in the GIMP's
1108 bugzilla.

1118 - the old dynaload code used Mach API functions to load dynamic
1119 libraries on Mac OS X. These APIs have been deprecated in OS X

1354 - reworked library probing, we can now set more than one probe
1355 function for a library. Disabled the default (non-freetype-config)
1356 library probe and added an extra probe function that searches for
1357 both ft2build.h and whatever it includes, and adds -I as needed.
1358 Hopefully this will fix build problems like

1426Imager 0.55 - 16 Dec 2006
1427===========
1428
1429This is primarily a bug fix release.
1430
1431Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1432
1433There is one new feature:
1434
1435 - the Win32 font driver now supports UTF8 (RT 22166)
1436 http://www.cpanforum.com/threads/3276
1437 http://rt.cpan.org/Ticket/Display.html?id=22166
1438
1439Several bugs were fixed:
1440
1441 - the string() method would not output the string "0"
1442 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1443
1444 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1445 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1446
1447 - the gif_disposal and gif_user_input tags weren't being read from
1448 the file correctly
1449 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1450
1451 - gif.c was failing to build under MSVC
1452 http://rt.cpan.org/Ticket/Display.html?id=23922
1453
1454 - in some cases strings passed to the string() method were treated as
1455 terminated by NUL (chr 0)
1456 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1457
1458 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1459 that's the default build name for zlib on Win32.
1460 http://rt.cpan.org/Ticket/Display.html?id=23064
1461
1462 - search $Config{incpath} for headers too, which we should have been
1463 doing all along.
1464
1465Win32 font driver fixes:
1466
1467 - the global descent value from bounding box was the wrong sign
1468 http://www.cpanforum.com/threads/3276
1469
1470 - if the first or last glyph overflowed the left or right side of the
1471 advance width they would be clipped
1472
1473
1474Imager 0.54 - 14 Sep 2006
1475===========
1476
1477This is primarily a feature release:
1478
1479 - a new qtype value 'mixing' has been added to the scale()
1480 method. This is faster than 'normal', slower than 'preview'. This
1481 is based on the method used by pnmscale, and seems to produce less
1482 blurry results than normal.
1483 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1484
1485 - the rubthrough() method can now render onto images with an alpha
1486 channel.
1487 http://rt.cpan.org/Ticket/Display.html?id=20678
1488
1489 - the read_multi() method now falls back to calling doing a single
1490 image read via the read() method and write_multi() will now fall
1491 back to calling write() if a single image is supplied. This means
1492 you can simply call the read_multi() or write_multi() functions
1493 without having to check if the type is formatted by that method.
1494 http://rt.cpan.org/Ticket/Display.html?id=19457
1495 http://rt.cpan.org/Ticket/Display.html?id=19458
1496
1497 - the GIF loop extension can now be written. If you don't have
1498 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1499 should upgrade.
1500 http://rt.cpan.org/Ticket/Display.html?id=21185
1501
1502 - getscanline() and setscanline() can now read/write palette index
1503 based data from/to the image for paletted images, by setting type to
1504 'index'.
1505 http://rt.cpan.org/Ticket/Display.html?id=20338
1506
1507 - we no longer hassle you to disable GIF support
1508 http://rt.cpan.org/Ticket/Display.html?id=20687
1509
1510 - minor documentation fixes
1511
1512
1513Imager 0.53 - 26 Jul 2006
1514===========
1515
1516This is a bugfix release.
1517
1518Some test code was left in a code path not covered by the test
1519suite. A test was added to cover this code path and the test code was
1520removed.

1522
1523
1524Imager 0.52 - 25 Jul 2006
1525===========
1526
1527This is primarily a feature release, but contains a fair few bug
1528fixes, new features:
1529
1530 - ability to read and write MS Windows ICO and CUR files
1531
1532 - you can now add file format plugins to support new file formats
1533
1534 - add POD coverage tests
1535
1536 - setcolors() and addcolors() now accept color names and so on
1537 instead of requiring Imager::Color objects.
1538 http://rt.cpan.org/Ticket/Display.html?id=20056
1539
1540 - flood_fill() can now fill to a specified border color instead of
1541 just to the area the same color as the seed.
1542 http://rt.cpan.org/Ticket/Display.html?id=19618
1543
1544
1545Bug fixes:
1546
1547 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1548 calculating the advance width.
1549 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1550
1551 - bounding_box for the T1 driver wasn't including leading and
1552 trailing spaces in the bounding box as the other drivers did, it also
1553 produced strange results for empty strings or strings containing only
1554 spaces
1555
1556 - when reading CMYK jpeg images they were being transferred to the
1557 image object as is, producing a four channel image. It only looked ok
1558 due to an old still unfixed Photoshop bug. We now convert from the
1559 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1560 http://rt.cpan.org/Ticket/Display.html?id=20416
1561
1562 - reading a CYMK TIFF would result in a 4 channel image, reading any
1563 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1564 result in an error.
1565 http://rt.cpan.org/Ticket/Display.html?id=20415
1566
1567 - added /usr/local/include to the default include search path, since
1568 we were already searching /usr/local/lib for libraries.
1569
1570And various minor fixes and documentation updates.
1571
1572
1573Imager 0.51 - 23 Apr 2006

1577 a crash
1578 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1579
1580 - fix mis-processing of the src_maxx and src_maxy parameters of the
1581 paste() method
1582 http://rt.cpan.org/Public/Bug/Display.html?id=18712

1594 output is an in-memeory buffer.

1596
1597 - fixes an incorrect pointer parameter in the PNG code
1598 http://rt.cpan.org/Public/Bug/Display.html?id=18051
