289d65f4
TC
12 - The size of rotated images is no longer rounded up so aggressively.
13 Added rounding to the linear interpolation done for rotate() and
14 matrix_transform() for 1 and 3 channel 8-bit images.
15 Adjusted the two tranlate matrices used to build the final rotation
16 matrix to use the distance between the outlier pixels rather than
17 the pixel dimensions (ie. dimension-1).
18 With all of this the output of rotate(degrees => 270) on an 8-bit
19 image exactly matches the output of rotate(right => 270).

22Other changes:
23
24 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
25 internals, those names only matter for the XS interface.
26
27 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
28 the API level compiled into a loadable module such as
29 Imager::File::GIF doesn't match that of Imager. Previously it
30 could be difficult to determine exactly which module was failing to
31 load.
32 https://rt.cpan.org/Ticket/Display.html?id=77173
33
34 - added Imager->check_file_limits() as an interface to the
35 i_int_check_image_file_limits() API.
36
37 - Imager->set_file_limits(reset => 1) now resets the limits to the
38 defaults rather than setting them all to unlimited.
39
40 - wrote a brief security note as Imager::Security

44===========
45
46Bug fixes:
47
48 - Imager::Test::is_imaged() attempted to process an "epsilon"
49 parameter but the prototype didn't allow for the extra parameter.
50 Corrected the prototype.
51
29b38678
TC
52 - when downconverting samples (eg. from floating point to 8 bit)
53 Imager now rounds the sample value rather than attempting to
54 allocate input values over output values equally. The old
55 behaviour had the probably surprising effect of converting a
56 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
57 2.
58 This may result in slightly different 8 or 16-bit output images.
59
e2a86bac
TC
60 - BI_BITFIELD BMP images were handled incorrectly, both in
61 incorrectly calculating the space required for the masks and in
62 processing the image data itself.
63 https://rt.cpan.org/Ticket/Display.html?id=76736
64
65 - some odd width BMP BI_RLE4 images use run lengths that run one off
66 the edge of the image. Imager now allows this, discarding the
67 extra column.
68
69 - odd length RLE4 runs in BMP images were decoded incorrectly.
70

TC
71 - pkg-config could sometimes return a library that was in a directory
72 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
73 If no -L is included in the pkg-config library information check if
74 EU::MM can find the library, and if not, search our configured
75 directories and insert that into the library flags.
76 https://rt.cpan.org/Ticket/Display.html?id=75869
77
de50f459
TC
78 - Imager::Probe can now probe for libraries with dependent libraries,
79 common for static linking, eg. libpng requires libz.
80 https://rt.cpan.org/Ticket/Display.html?id=74043
81
82 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
83
84 - added alternative probe configurations that try to link libz, to
85 handle a statically linked libpng.
86 https://rt.cpan.org/Ticket/Display.html?id=74043
87
88 - if a probe includes testcode, Imager::Probe now checks that code as
89 part of the process of checking each configuration rather than as a
90 post test of the found configuration. This allows alternate
91 configurations to be checked if a matching but non-working
92 configuration is found.
93 https://rt.cpan.org/Ticket/Display.html?id=74043
94
9d5ff8a6
TC
95Other changes:
96
97 - when reading or writing images via callbacks, the default callbacks
98 now push an error message indicating that a required callback was
99 called but not supplied.
100 https://rt.cpan.org/Ticket/Display.html?id=76782
101
102 - clarify which callbacks are required for reading and writing TIFF
103 images.
104
105 - improve logging for creation of callback I/O layers.
106

109 - the i_get_file_background() and i_get_file_backgroundf() APIs now
110 return int to indicate whether the i_background tag was found.

112 - PNG rework
113 - improve error reporting
114 - add png_interlace, png_bits tags
115 - read paletted images as paletted images, including transparency
116 - read 1 bit greyscale images as a type suitable for other file
117 handlers to write as bilevel
118 - read 16 bit/sample PNG as 16-bit/sample Imager images
119 - write "bilevel" paletted images as 1 bit grayscale images
120 - write paletted images as paletted images
121 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
122 images

141 - Imager (and the bundled dynamic modules) no longer fallback to
142 using DynaLoader if loading via XSLoader fails.
143 For the bundled modules this could hide useful error messages.

145
335078fc
TC
146 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
147 buffer in the array of allocations, but just stores the filename
148 pointer and line number.

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

TC
165 - note that the generator of the apparently non-DFSG-free postscript
166 in MMOne.pfb is a Debian package.
167
02323e69
TC
168 - setsamples() is now a true complement to getsamples() - it can
169 write 8-bit or floating point samples from a scalar or array
170 reference. This adds i_psamp() and i_psampf() to the C level API.
171
172 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
173 changed to make better use of the typemap, but these aren't part of
174 the perl level API anyway. There were no changes to the C level
175 interfaces to these functions.
176
2a27eeff
TC
177 - getpixel() and setpixel() now accept a mix of scalar and array
178 references for the x and y parameters, and unequal array lengths is
179 no longer an error.

201
2a27eeff

223 - make the error message from read() or read_multi() when they can't
224 identify the file type match reality.
225 https://rt.cpan.org/Ticket/Display.html?id=72475
226
227 - read() now uses $FORMATGUESS if it can't determine the file type
228 based on the file header, to match read_multi().
229

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

289 creation.
290
291 - Imager::Font->new now produces better error messages for the T1
292 engine.
293
6e938c74
TC
294 - the font has_chars() method now returns perl's true and false
295 values in list context rather than integers, which should be more

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

327
328 - add simple tests for the Imager::Test test_image generators
329

TC
330 - io_glue I/O buffering re-work:
331
332 - reorganize io_glue to do it's own buffering by default
333
334 - the unbuffered functions are available as i_io_raw_read() (or
335 raw_read() from perl) etc but are not recommended for typical
336 use.
337
338 - use the new i_io_peekn() when checking for file magic to avoid
339 seek, allowing Imager to detect the file type and read the file
340 from an unseekable stream (for formats that don't use random
341 access)
342
343 - added several new I/O layer API functions.
344
345 - fix the TGA performance problem, most noticably on Win32
346 https://rt.cpan.org/Ticket/Display.html?id=70037
347
348 - TIFF now uses wrapper functions of the correct types to avoid casts
349 https://rt.cpan.org/Ticket/Display.html?id=69912
350
351 - the callback IO object did its own buffering, controlled by the
352 maxbuffer parameter supplied to the read() and write() methods.
353 This buffering has been removed, to avoid redundancy with the
354 common io_glue buffering. This also avoids a bug in that code
355 which could rarely pass a zero length to the read callback and
356 then panic about the result.
357
358 - the callback IO object now tests the result of calling the close
359 callback, which should return true for success.
360
361 - the PNM reader did its own buffering. This buffering has been
362 removed to avoid redundancy with the common io_glue buffering.
363
364 - previously the read handlers for fd and callback I/O layers would
365 call the underlying interface (POSIX read or your supplied callback)
366 until it filled the buffer. It now only makes one call.
367
368 - added public constructors for I/O layer objects (see Imager::IO)
369
370 - all core file handlers now use the i_io_foo() wrappers to gain
371 access to buffered I/O rather than calling the I/O layer
372 callbacks directly.
373
374 - all core file handlers now check for error on close.
375
376 - Backward compatibility: if you hava custom file handlers, you can
377 use i_io_write() etc since they're available as macros in older
378 versions of Imager.
379
380 - eliminate the final remnants of io_glue_commit_types().
381
382 - bump IMAGER_API_VERSION, since the above may break assumptions.
383
384 - removed the long unused i_gen_reader() and i_gen_writer() utility
385 functions.

TC
390The main changes in the release versus 0.84 are:
391
392 - on 64-bit systems, 64-bit types are consistently used for image
393 dimensions and co-ordinated, and for memory block sizes.
394
395 - handle IFD loops in TIFF files correctly. Previously this would
396 lead to an infinite loop.

446==============
447
448Development release as a sanity check for the types re-work.
8d14daab
TC
449
450Massive types re-work:
451
452 - the type used internally for pixel co-ordinates and image sizes is
453 now 64-bit on 64-bit platforms (at least sane ones).
454
455 - size_t is now used consistently for memory block sizes.
456
457 - since this changes the binary interface, the Imager API version has
458 been incremented. Any module that uses the API will need to be
459 rebuilt. In most cases that will be enough, but calls to any APIs
460 that take a pointer to image sizes may need source changes.
461
462 - you should be able to create very large images on 64-bit systems,

926 - the conv filter now enforces that the sum of the coefficients is
927 non-zero. Also, rather than skipping pixels off the edge off the
928 edge of the image, the closest edge pixel is used. Previously
929 dividing by the zero sum of coefficients could cause invalid
930 results or runtime exceptions.

1126 - moved the imtoc.perl code into Imager::Preprocess

1128 - paste() and rubthrough() now adapt the source image data to the
1129 destination, so you can now safely paste/rubthrough from greyscale

1131 noalpha channels or back.
1132 https://rt.cpan.org/Ticket/Display.html?id=30908
1133
1134 - rubthrough() now falls back to pasting when the source doesn't have
1135 an alpha channel. This effectively treats the source as having a
1136 max alpha channel, the right thing to do.
1137 http://rt.cpan.org/Ticket/Display.html?id=29944
1138
1139 - re-worked most of the area filling code to use a common set of
1140 functions when filling.
1141 Corrected normal combine mode.
1142 Rewrote most of the combine modes to match the way the SVG draft
1143 defines them with respect to a translucent source and destination.

1146 similarly.

1186 changed to match the behaviour of the GIMP. Previously the bit
1187 being set was treated as an opaque pixel, but one user reported a
1188 problem with loading such an image. I haven't been able to find any
1189 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1190 I'll match it's behaviour. See issue 114913 in the GIMP's
1191 bugzilla.

1348 - the mask for ICO/CUR images is now applied as an alpha channel to
1349 the returned image. For the old behaviour, supply ico_masked => 0
1350 to read() or read_multi(). This should be less confusing when
1351 using Imager as a general image processor.

1354Bug fixes:

1356 - in some cases it's possible for giflib/libungif to return color
1357 indexes outside the range of colors defined by the image's palette.
1358 We now expand the palette to match the indexes used.
1359 Thanks to Gabriel Vasseur for reporting this.

1364 - to avoid confusion, channels not present in the image are returned as
1365 zero by getscanline(). This has no effect on the C level i_glin()

1367 channels.

1509Imager 0.55 - 16 Dec 2006
1510===========
1511
1512This is primarily a bug fix release.
1513
1514Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1515
1516There is one new feature:
1517
1518 - the Win32 font driver now supports UTF8 (RT 22166)
1519 http://www.cpanforum.com/threads/3276
1520 http://rt.cpan.org/Ticket/Display.html?id=22166
1521
1522Several bugs were fixed:
1523
1524 - the string() method would not output the string "0"
1525 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1526
1527 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1528 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1529
1530 - the gif_disposal and gif_user_input tags weren't being read from
1531 the file correctly
1532 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1533
1534 - gif.c was failing to build under MSVC
1535 http://rt.cpan.org/Ticket/Display.html?id=23922
1536
1537 - in some cases strings passed to the string() method were treated as
1538 terminated by NUL (chr 0)
1539 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1540
1541 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1542 that's the default build name for zlib on Win32.
1543 http://rt.cpan.org/Ticket/Display.html?id=23064
1544
1545 - search $Config{incpath} for headers too, which we should have been
1546 doing all along.
1547
1548Win32 font driver fixes:
1549
1550 - the global descent value from bounding box was the wrong sign
1551 http://www.cpanforum.com/threads/3276
1552
1553 - if the first or last glyph overflowed the left or right side of the
1554 advance width they would be clipped
1555
1556
1557Imager 0.54 - 14 Sep 2006
1558===========
1559
1560This is primarily a feature release:
1561
1562 - a new qtype value 'mixing' has been added to the scale()
1563 method. This is faster than 'normal', slower than 'preview'. This
1564 is based on the method used by pnmscale, and seems to produce less
1565 blurry results than normal.
1566 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1567
1568 - the rubthrough() method can now render onto images with an alpha
1569 channel.
1570 http://rt.cpan.org/Ticket/Display.html?id=20678
1571
1572 - the read_multi() method now falls back to calling doing a single
1573 image read via the read() method and write_multi() will now fall
1574 back to calling write() if a single image is supplied. This means
1575 you can simply call the read_multi() or write_multi() functions
1576 without having to check if the type is formatted by that method.
1577 http://rt.cpan.org/Ticket/Display.html?id=19457
1578 http://rt.cpan.org/Ticket/Display.html?id=19458
1579
1580 - the GIF loop extension can now be written. If you don't have
1581 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1582 should upgrade.
1583 http://rt.cpan.org/Ticket/Display.html?id=21185
1584
1585 - getscanline() and setscanline() can now read/write palette index
1586 based data from/to the image for paletted images, by setting type to
1587 'index'.
1588 http://rt.cpan.org/Ticket/Display.html?id=20338
1589
1590 - we no longer hassle you to disable GIF support
1591 http://rt.cpan.org/Ticket/Display.html?id=20687
1592
1593 - minor documentation fixes
1594
1595
1596Imager 0.53 - 26 Jul 2006
1597===========
1598
1599This is a bugfix release.
1600
1601Some test code was left in a code path not covered by the test
1602suite. A test was added to cover this code path and the test code was
1603removed.

1606
1607Imager 0.52 - 25 Jul 2006
1608===========
1609
1610This is primarily a feature release, but contains a fair few bug
1611fixes, new features:
1612
1613 - ability to read and write MS Windows ICO and CUR files
1614
1615 - you can now add file format plugins to support new file formats
1616
1617 - add POD coverage tests
1618
1619 - setcolors() and addcolors() now accept color names and so on
1620 instead of requiring Imager::Color objects.
1621 http://rt.cpan.org/Ticket/Display.html?id=20056
1622
1623 - flood_fill() can now fill to a specified border color instead of
1624 just to the area the same color as the seed.
1625 http://rt.cpan.org/Ticket/Display.html?id=19618
1626
1627
1628Bug fixes:
1629
1630 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1631 calculating the advance width.
1632 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1633
1634 - bounding_box for the T1 driver wasn't including leading and
1635 trailing spaces in the bounding box as the other drivers did, it also
1636 produced strange results for empty strings or strings containing only
1637 spaces
1638
1639 - when reading CMYK jpeg images they were being transferred to the
1640 image object as is, producing a four channel image. It only looked ok
1641 due to an old still unfixed Photoshop bug. We now convert from the
1642 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1643 http://rt.cpan.org/Ticket/Display.html?id=20416
1644
1645 - reading a CYMK TIFF would result in a 4 channel image, reading any
1646 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1647 result in an error.
1648 http://rt.cpan.org/Ticket/Display.html?id=20415
1649
1650 - added /usr/local/include to the default include search path, since
1651 we were already searching /usr/local/lib for libraries.
1652
1653And various minor fixes and documentation updates.
1654
1655
1656Imager 0.51 - 23 Apr 2006

1662
1663 - fix mis-processing of the src_maxx and src_maxy parameters of the

1677 output is an in-memeory buffer.
