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

TC
31 - pkg-config could sometimes return a library that was in a directory
32 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
33 If no -L is included in the pkg-config library information check if
34 EU::MM can find the library, and if not, search our configured
35 directories and insert that into the library flags.
36 https://rt.cpan.org/Ticket/Display.html?id=75869
37
9d5ff8a6
TC
38Other changes:
39
40 - when reading or writing images via callbacks, the default callbacks
41 now push an error message indicating that a required callback was
42 called but not supplied.
43 https://rt.cpan.org/Ticket/Display.html?id=76782
44
45 - clarify which callbacks are required for reading and writing TIFF
46 images.
47
48 - improve logging for creation of callback I/O layers.

50Imager 0.89 - 18 Mar 2012
51===========
52
53Bug fixes:
54
93eab01e
TC
55 - getpixel(..., type => "float") and the API i_gpixf() have been
56 broken on paletted images since they were implemented.

59Other changes:

TC
61 - links in the METHOD INDEX now point at the method documentation
62 rather than the heading you can find them under.
63 https://rt.cpan.org/Ticket/Display.html?id=71495
64
a5919365
TC
65 - Imager (and the bundled dynamic modules) no longer fallback to
66 using DynaLoader if loading via XSLoader fails.
67 For the bundled modules this could hide useful error messages.
68 https://rt.cpan.org/Ticket/Display.html?id=75560
69
335078fc
TC
70 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
71 buffer in the array of allocations, but just stores the filename
72 pointer and line number.

75Imager 0.88 - 22 Feb 2012
76===========
77
43bef43b
TC
78 - describe how to build libgif etc on OS X in such a way as to be
79 compatible with a fat binary perl (such as the system perl), in
80 README.
81 https://rt.cpan.org/Ticket/Display.html?id=73371
82
69675eef
TC
83 - update the change notes for 0.77_01 to indicate that libungif
84 support was removed.
85
d4056453
TC
86 - add some other imaging modules to SEE ALSO
87 https://rt.cpan.org/Ticket/Display.html?id=73906
88
3b7f10da
TC
89 - note that the generator of the apparently non-DFSG-free postscript
90 in MMOne.pfb is a Debian package.
91
02323e69
TC
92 - setsamples() is now a true complement to getsamples() - it can
93 write 8-bit or floating point samples from a scalar or array
94 reference. This adds i_psamp() and i_psampf() to the C level API.
95
96 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
97 changed to make better use of the typemap, but these aren't part of
98 the perl level API anyway. There were no changes to the C level
99 interfaces to these functions.
100
2a27eeff
TC
101 - getpixel() and setpixel() now accept a mix of scalar and array
102 references for the x and y parameters, and unequal array lengths is
103 no longer an error.
104 https://rt.cpan.org/Ticket/Display.html?id=73697

114
5091168a
TC
115 - Win32 text output is now done in normal combine mode, the alpha
116 component of the color is now significant.

119 - remove long unused gif case from read()
120 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
121
7640e3bb
TC
122 - the getsamples() target parameter was being treated as a hashref
123 when it's meant to be an array reference.
124 https://rt.cpan.org/Ticket/Display.html?id=74882
125
2a27eeff
TC
126 - getpixel() and setpixel() now returns an empty list when invalid
127 parameters are supplied.
128 Invalid values for type now result in an error for getpixel().

TC
147 - make the error message from read() or read_multi() when they can't
148 identify the file type match reality.
149 https://rt.cpan.org/Ticket/Display.html?id=72475
150
151 - read() now uses $FORMATGUESS if it can't determine the file type
152 based on the file header, to match read_multi().
153
154 - re-work and add tests for def_guess_type(). def_guess_type() no
155 longer returns any random file extension as the file type.
156

166
a044f2c6
TC
167 - fix i_render_color() to properly draw in "normal" mode - ie. when
168 writing to a 1 or 3 channel image the second or fourth channel of
169 the source color was being ignored, it is now significant.

202
954ac5d1
TC
203 - depend on Scalar::Util, since we use it and older perls don't have
204 it.
205
5efba0c6
TC
206 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
207 to synthesize it from overloaded "".
208
73e3ff55
TC
209 - use T1_StrError() for error messages on modern libt1
210 https://rt.cpan.org/Ticket/Display.html?id=69879
211
212 - actually load the font rather than just adding it to the catalog on
213 creation.
214
215 - Imager::Font->new now produces better error messages for the T1
216 engine.
217
6e938c74
TC
218 - the font has_chars() method now returns perl's true and false
219 values in list context rather than integers, which should be more
220 efficient.

235 https://rt.cpan.org/Ticket/Display.html?id=71675
236
336ce474
TC
237 - we rely on Config.pm's d_vsnprintf as to whether we use
238 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
239 though it only has _ prefixed versions of these. Define our own
240 prefixed names on Win32.

6d5c85a2 250==============
a7e32beb
TC
251
252 - add simple tests for the Imager::Test test_image generators
253
6d5c85a2
TC
254 - io_glue I/O buffering re-work:
255
256 - reorganize io_glue to do it's own buffering by default
257
258 - the unbuffered functions are available as i_io_raw_read() (or
259 raw_read() from perl) etc but are not recommended for typical
260 use.
261
262 - use the new i_io_peekn() when checking for file magic to avoid
263 seek, allowing Imager to detect the file type and read the file
264 from an unseekable stream (for formats that don't use random
265 access)
266
267 - added several new I/O layer API functions.
268
269 - fix the TGA performance problem, most noticably on Win32
270 https://rt.cpan.org/Ticket/Display.html?id=70037
271
272 - TIFF now uses wrapper functions of the correct types to avoid casts
273 https://rt.cpan.org/Ticket/Display.html?id=69912
274
275 - the callback IO object did its own buffering, controlled by the
276 maxbuffer parameter supplied to the read() and write() methods.
277 This buffering has been removed, to avoid redundancy with the
278 common io_glue buffering. This also avoids a bug in that code
279 which could rarely pass a zero length to the read callback and
280 then panic about the result.
281
282 - the callback IO object now tests the result of calling the close
283 callback, which should return true for success.
284
285 - the PNM reader did its own buffering. This buffering has been
286 removed to avoid redundancy with the common io_glue buffering.
287
288 - previously the read handlers for fd and callback I/O layers would
289 call the underlying interface (POSIX read or your supplied callback)
290 until it filled the buffer. It now only makes one call.
291
292 - added public constructors for I/O layer objects (see Imager::IO)
293
294 - all core file handlers now use the i_io_foo() wrappers to gain
295 access to buffered I/O rather than calling the I/O layer
296 callbacks directly.
297
298 - all core file handlers now check for error on close.
299
300 - Backward compatibility: if you hava custom file handlers, you can
301 use i_io_write() etc since they're available as macros in older
302 versions of Imager.
303
304 - eliminate the final remnants of io_glue_commit_types().
305
306 - bump IMAGER_API_VERSION, since the above may break assumptions.
307
308 - removed the long unused i_gen_reader() and i_gen_writer() utility
309 functions.

6ad7e4bc
TC
312===========
313
0c647c9a
TC
314The main changes in the release versus 0.84 are:
315
316 - on 64-bit systems, 64-bit types are consistently used for image
317 dimensions and co-ordinated, and for memory block sizes.
318
319 - handle IFD loops in TIFF files correctly. Previously this would
320 lead to an infinite loop.
321
6ad7e4bc
TC
322Bug fixes:
323

334 - the image file limits set by set_file_limits() weren't being
335 checked when reading TIFF files.

337
5970bd39

340 https://rt.cpan.org/Ticket/Display.html?id=69194
341
4ce3551c
TC
342 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
343 through TIFF images, since it checks for IFD loops.
344 https://rt.cpan.org/Ticket/Display.html?id=69914
345
a16bca6d
TC
346 - don't leak memory when out of range palette indexes are supplied to
347 setscanline().
348 https://rt.cpan.org/Ticket/Display.html?id=69242
349
350 - require a later version of CPAN::Meta to ensure JSON::PP and

369Imager 0.84_01 - 8 Aug 2011
370==============
371
372Development release as a sanity check for the types re-work.
8d14daab
TC
373
374Massive types re-work:
375
376 - the type used internally for pixel co-ordinates and image sizes is
377 now 64-bit on 64-bit platforms (at least sane ones).
378
379 - size_t is now used consistently for memory block sizes.
380
381 - since this changes the binary interface, the Imager API version has
382 been incremented. Any module that uses the API will need to be
383 rebuilt. In most cases that will be enough, but calls to any APIs
384 that take a pointer to image sizes may need source changes.
385
386 - you should be able to create very large images on 64-bit systems,
387 if you have enough memory. Successfully created a 32768 x 49192 x
388 3 channel image, filled with a tiled image and scaled it. The
389 unscaled image was also successfully saved to a JPEG.
390
391 - check the image size before attempting to write BMP, GIF, JPEG,
392 PNG, SGI, TGA, TIFF images.
393
394 - correctly handle reading TGA images over 32767 pixels wide or tall.
395
396Incidental changes:
397
398 - the gif_left and gif_top tags are now clamped to non-negative
399 values when writing a GIF image.
400
401 - removed dead callback read/write code
402
403The default maximum memory size when reading files is now 1G.

432 translation.
433 https://rt.cpan.org/Ticket/Display.html?id=68508
434
59c150a4
TC
435 - writing a paletted image to GIF wouldn't always use the colors
436 supplied (or generated, eg. via make_colors => "mono"), which was
437 confusing at best.

1041This release primarily contains changes to improve ease of use -
1042rather than you having to convert images to the appropriate number of
1043channels, Imager handles it internally. How to handle drawing colors
1044and the default combine mode is a thornier problem left for some other
1045release.

TC
1050 - moved the imtoc.perl code into Imager::Preprocess
1051
1052 - paste() and rubthrough() now adapt the source image data to the
1053 destination, so you can now safely paste/rubthrough from greyscale
1054 images to color images or back, or from alpha channel images to
1055 noalpha channels or back.
1056 https://rt.cpan.org/Ticket/Display.html?id=30908
1057
1058 - rubthrough() now falls back to pasting when the source doesn't have
1059 an alpha channel. This effectively treats the source as having a
1060 max alpha channel, the right thing to do.
1061 http://rt.cpan.org/Ticket/Display.html?id=29944
1062
1063 - re-worked most of the area filling code to use a common set of
1064 functions when filling.
1065 Corrected normal combine mode.
1066 Rewrote most of the combine modes to match the way the SVG draft
1067 defines them with respect to a translucent source and destination.
1068 Added tests for translucent source and destination.
1069 Added tests to check 8-bit/sample and double/sample combines work
1070 similarly.

1109 - handling of the left-over bit for 16-bit/pixel TGA images has been
1110 changed to match the behaviour of the GIMP. Previously the bit
1111 being set was treated as an opaque pixel, but one user reported a
1112 problem with loading such an image. I haven't been able to find any
1113 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1114 I'll match it's behaviour. See issue 114913 in the GIMP's
1115 bugzilla.

1125 - the old dynaload code used Mach API functions to load dynamic
1126 libraries on Mac OS X. These APIs have been deprecated in OS X

1361 - reworked library probing, we can now set more than one probe
1362 function for a library. Disabled the default (non-freetype-config)
1363 library probe and added an extra probe function that searches for
1364 both ft2build.h and whatever it includes, and adds -I as needed.
1365 Hopefully this will fix build problems like

1433Imager 0.55 - 16 Dec 2006
1434===========
1435
1436This is primarily a bug fix release.
1437
1438Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1439
1440There is one new feature:
1441
1442 - the Win32 font driver now supports UTF8 (RT 22166)
1443 http://www.cpanforum.com/threads/3276
1444 http://rt.cpan.org/Ticket/Display.html?id=22166
1445
1446Several bugs were fixed:
1447
1448 - the string() method would not output the string "0"
1449 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1450
1451 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1452 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1453
1454 - the gif_disposal and gif_user_input tags weren't being read from
1455 the file correctly
1456 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1457
1458 - gif.c was failing to build under MSVC
1459 http://rt.cpan.org/Ticket/Display.html?id=23922
1460
1461 - in some cases strings passed to the string() method were treated as
1462 terminated by NUL (chr 0)
1463 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1464
1465 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1466 that's the default build name for zlib on Win32.
1467 http://rt.cpan.org/Ticket/Display.html?id=23064
1468
1469 - search $Config{incpath} for headers too, which we should have been
1470 doing all along.
1471
1472Win32 font driver fixes:
1473
1474 - the global descent value from bounding box was the wrong sign
1475 http://www.cpanforum.com/threads/3276
1476
1477 - if the first or last glyph overflowed the left or right side of the
1478 advance width they would be clipped
1479
1480
1481Imager 0.54 - 14 Sep 2006
1482===========
1483
1484This is primarily a feature release:
1485
1486 - a new qtype value 'mixing' has been added to the scale()
1487 method. This is faster than 'normal', slower than 'preview'. This
1488 is based on the method used by pnmscale, and seems to produce less
1489 blurry results than normal.
1490 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1491
1492 - the rubthrough() method can now render onto images with an alpha
1493 channel.
1494 http://rt.cpan.org/Ticket/Display.html?id=20678
1495
1496 - the read_multi() method now falls back to calling doing a single
1497 image read via the read() method and write_multi() will now fall
1498 back to calling write() if a single image is supplied. This means
1499 you can simply call the read_multi() or write_multi() functions
1500 without having to check if the type is formatted by that method.
1501 http://rt.cpan.org/Ticket/Display.html?id=19457
1502 http://rt.cpan.org/Ticket/Display.html?id=19458
1503
1504 - the GIF loop extension can now be written. If you don't have
1505 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1506 should upgrade.
1507 http://rt.cpan.org/Ticket/Display.html?id=21185
1508
1509 - getscanline() and setscanline() can now read/write palette index
1510 based data from/to the image for paletted images, by setting type to
1511 'index'.
1512 http://rt.cpan.org/Ticket/Display.html?id=20338
1513
1514 - we no longer hassle you to disable GIF support
1515 http://rt.cpan.org/Ticket/Display.html?id=20687
1516
1517 - minor documentation fixes
1518
1519
1520Imager 0.53 - 26 Jul 2006
1521===========
1522
1523This is a bugfix release.
1524
1525Some test code was left in a code path not covered by the test
1526suite. A test was added to cover this code path and the test code was
1527removed.
1528http://rt.cpan.org/Public/Bug/Display.html?id=20705
1529
1530
1531Imager 0.52 - 25 Jul 2006
1532===========
1533
1534This is primarily a feature release, but contains a fair few bug
1535fixes, new features:
1536
1537 - ability to read and write MS Windows ICO and CUR files
1538
1539 - you can now add file format plugins to support new file formats
1540
1541 - add POD coverage tests
1542
1543 - setcolors() and addcolors() now accept color names and so on
1544 instead of requiring Imager::Color objects.
1545 http://rt.cpan.org/Ticket/Display.html?id=20056
1546
1547 - flood_fill() can now fill to a specified border color instead of
1548 just to the area the same color as the seed.
1549 http://rt.cpan.org/Ticket/Display.html?id=19618
1550
1551
1552Bug fixes:
1553
1554 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1555 calculating the advance width.
1556 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1557
1558 - bounding_box for the T1 driver wasn't including leading and
1559 trailing spaces in the bounding box as the other drivers did, it also
1560 produced strange results for empty strings or strings containing only
1561 spaces
1562
1563 - when reading CMYK jpeg images they were being transferred to the
1564 image object as is, producing a four channel image. It only looked ok
1565 due to an old still unfixed Photoshop bug. We now convert from the
1566 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1567 http://rt.cpan.org/Ticket/Display.html?id=20416
1568
1569 - reading a CYMK TIFF would result in a 4 channel image, reading any
1570 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1571 result in an error.
1572 http://rt.cpan.org/Ticket/Display.html?id=20415
1573
1574 - added /usr/local/include to the default include search path, since
1575 we were already searching /usr/local/lib for libraries.
1576
1577And various minor fixes and documentation updates.
1578
1579

1586
1587 - fix mis-processing of the src_maxx and src_maxy parameters of the
1588 paste() method
