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

24Other changes:
25
26 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
27 internals, those names only matter for the XS interface.
28
29 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
30 the API level compiled into a loadable module such as
31 Imager::File::GIF doesn't match that of Imager. Previously it
32 could be difficult to determine exactly which module was failing to
33 load.
34 https://rt.cpan.org/Ticket/Display.html?id=77173
35
36 - added Imager->check_file_limits() as an interface to the
37 i_int_check_image_file_limits() API.
38
39 - Imager->set_file_limits(reset => 1) now resets the limits to the
40 defaults rather than setting them all to unlimited.
41
42 - wrote a brief security note as Imager::Security

46===========
47
48Bug fixes:
49
50 - Imager::Test::is_imaged() attempted to process an "epsilon"
51 parameter but the prototype didn't allow for the extra parameter.
52 Corrected the prototype.
53
29b38678
TC
54 - when downconverting samples (eg. from floating point to 8 bit)
55 Imager now rounds the sample value rather than attempting to
56 allocate input values over output values equally. The old
57 behaviour had the probably surprising effect of converting a
58 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
59 2.
60 This may result in slightly different 8 or 16-bit output images.
61
e2a86bac
TC
62 - BI_BITFIELD BMP images were handled incorrectly, both in
63 incorrectly calculating the space required for the masks and in
64 processing the image data itself.
65 https://rt.cpan.org/Ticket/Display.html?id=76736
66
67 - some odd width BMP BI_RLE4 images use run lengths that run one off
68 the edge of the image. Imager now allows this, discarding the
69 extra column.
70
71 - odd length RLE4 runs in BMP images were decoded incorrectly.
72

TC
73 - pkg-config could sometimes return a library that was in a directory
74 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
75 If no -L is included in the pkg-config library information check if
76 EU::MM can find the library, and if not, search our configured
77 directories and insert that into the library flags.
78 https://rt.cpan.org/Ticket/Display.html?id=75869
79
de50f459
TC
80 - Imager::Probe can now probe for libraries with dependent libraries,
81 common for static linking, eg. libpng requires libz.
82 https://rt.cpan.org/Ticket/Display.html?id=74043
83
84 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
85
86 - added alternative probe configurations that try to link libz, to
87 handle a statically linked libpng.
88 https://rt.cpan.org/Ticket/Display.html?id=74043
89
90 - if a probe includes testcode, Imager::Probe now checks that code as
91 part of the process of checking each configuration rather than as a
92 post test of the found configuration. This allows alternate
93 configurations to be checked if a matching but non-working
94 configuration is found.
95 https://rt.cpan.org/Ticket/Display.html?id=74043

97Other changes:
98
99 - when reading or writing images via callbacks, the default callbacks
100 now push an error message indicating that a required callback was
101 called but not supplied.
102 https://rt.cpan.org/Ticket/Display.html?id=76782
103
104 - clarify which callbacks are required for reading and writing TIFF
105 images.
106
107 - improve logging for creation of callback I/O layers.
108

117 - read paletted images as paletted images, including transparency
118 - read 1 bit greyscale images as a type suitable for other file
119 handlers to write as bilevel
120 - read 16 bit/sample PNG as 16-bit/sample Imager images
121 - write "bilevel" paletted images as 1 bit grayscale images
122 - write paletted images as paletted images
123 - write 16-bit (or higher)/sample images as 16-bit/sample PNG

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

147

148 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a

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

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

200 - the getsamples() target parameter was being treated as a hashref
201 when it's meant to be an array reference.

203
2a27eeff
TC
204 - getpixel() and setpixel() now returns an empty list when invalid

226 identify the file type match reality.
227 https://rt.cpan.org/Ticket/Display.html?id=72475
228
229 - read() now uses $FORMATGUESS if it can't determine the file type
230 based on the file header, to match read_multi().
231

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

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

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

TC
329
330 - add simple tests for the Imager::Test test_image generators
331
6d5c85a2
TC
332 - io_glue I/O buffering re-work:
333
334 - reorganize io_glue to do it's own buffering by default
335
336 - the unbuffered functions are available as i_io_raw_read() (or
337 raw_read() from perl) etc but are not recommended for typical
338 use.
339
340 - use the new i_io_peekn() when checking for file magic to avoid
341 seek, allowing Imager to detect the file type and read the file
342 from an unseekable stream (for formats that don't use random
343 access)
344
345 - added several new I/O layer API functions.
346
347 - fix the TGA performance problem, most noticably on Win32
348 https://rt.cpan.org/Ticket/Display.html?id=70037
349
350 - TIFF now uses wrapper functions of the correct types to avoid casts
351 https://rt.cpan.org/Ticket/Display.html?id=69912
352
353 - the callback IO object did its own buffering, controlled by the
354 maxbuffer parameter supplied to the read() and write() methods.
355 This buffering has been removed, to avoid redundancy with the
356 common io_glue buffering. This also avoids a bug in that code
357 which could rarely pass a zero length to the read callback and
358 then panic about the result.
359
360 - the callback IO object now tests the result of calling the close
361 callback, which should return true for success.
362
363 - the PNM reader did its own buffering. This buffering has been
364 removed to avoid redundancy with the common io_glue buffering.
365
366 - previously the read handlers for fd and callback I/O layers would
367 call the underlying interface (POSIX read or your supplied callback)
368 until it filled the buffer. It now only makes one call.
369
370 - added public constructors for I/O layer objects (see Imager::IO)
371
372 - all core file handlers now use the i_io_foo() wrappers to gain
373 access to buffered I/O rather than calling the I/O layer
374 callbacks directly.
375
376 - all core file handlers now check for error on close.
377
378 - Backward compatibility: if you hava custom file handlers, you can
379 use i_io_write() etc since they're available as macros in older
380 versions of Imager.
381
382 - eliminate the final remnants of io_glue_commit_types().
383
384 - bump IMAGER_API_VERSION, since the above may break assumptions.
385
386 - removed the long unused i_gen_reader() and i_gen_writer() utility
387 functions.

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

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

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

1128 - moved the imtoc.perl code into Imager::Preprocess

1133 noalpha channels or back.
1134 https://rt.cpan.org/Ticket/Display.html?id=30908
1135
1136 - rubthrough() now falls back to pasting when the source doesn't have
1137 an alpha channel. This effectively treats the source as having a
1138 max alpha channel, the right thing to do.
1139 http://rt.cpan.org/Ticket/Display.html?id=29944
1140
1141 - re-worked most of the area filling code to use a common set of

1144 Rewrote most of the combine modes to match the way the SVG draft
1145 defines them with respect to a translucent source and destination.

1189 being set was treated as an opaque pixel, but one user reported a
1190 problem with loading such an image. I haven't been able to find any
1191 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1192 I'll match it's behaviour. See issue 114913 in the GIMP's
1193 bugzilla.

1338 - Finished/rewrote Arnar's old SGI RGB file format support, so Imager
1339 now has full SGI RGB image format, including RLE and 16-bit/sample
1340 images.

1350 - the mask for ICO/CUR images is now applied as an alpha channel to
1351 the returned image. For the old behaviour, supply ico_masked => 0
1352 to read() or read_multi(). This should be less confusing when
1353 using Imager as a general image processor.

1356Bug fixes:
1357
1358 - in some cases it's possible for giflib/libungif to return color
1359 indexes outside the range of colors defined by the image's palette.
1360 We now expand the palette to match the indexes used.
1361 Thanks to Gabriel Vasseur for reporting this.

1363 - fixed various memory leaks that could occur when failing to read png,
1364 jpeg, bmp or tga files.
1365

TC
1366 - to avoid confusion, channels not present in the image are returned as
1367 zero by getscanline(). This has no effect on the C level i_glin()
1368 and i_glinf() API functions which continue to not set the unused
1369 channels.

1371 - the convert() method now returns an image of the same sample size as
1372 the source image.

1440 function for a library. Disabled the default (non-freetype-config)
1441 library probe and added an extra probe function that searches for
1442 both ft2build.h and whatever it includes, and adds -I as needed.

1511Imager 0.55 - 16 Dec 2006
1512===========
1513
1514This is primarily a bug fix release.
1515
1516Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1517
1518There is one new feature:
1519
1520 - the Win32 font driver now supports UTF8 (RT 22166)
1521 http://www.cpanforum.com/threads/3276
1522 http://rt.cpan.org/Ticket/Display.html?id=22166
1523
1524Several bugs were fixed:
1525
1526 - the string() method would not output the string "0"
1527 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1528
1529 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1530 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1531
1532 - the gif_disposal and gif_user_input tags weren't being read from
1533 the file correctly
1534 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1535
1536 - gif.c was failing to build under MSVC
1537 http://rt.cpan.org/Ticket/Display.html?id=23922
1538
1539 - in some cases strings passed to the string() method were treated as
1540 terminated by NUL (chr 0)
1541 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1542
1543 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1544 that's the default build name for zlib on Win32.
1545 http://rt.cpan.org/Ticket/Display.html?id=23064
1546
1547 - search $Config{incpath} for headers too, which we should have been
1548 doing all along.
1549
1550Win32 font driver fixes:
1551
1552 - the global descent value from bounding box was the wrong sign
1553 http://www.cpanforum.com/threads/3276
1554
1555 - if the first or last glyph overflowed the left or right side of the
1556 advance width they would be clipped
1557
1558
1559Imager 0.54 - 14 Sep 2006
1560===========
1561
1562This is primarily a feature release:
1563
1564 - a new qtype value 'mixing' has been added to the scale()
1565 method. This is faster than 'normal', slower than 'preview'. This
1566 is based on the method used by pnmscale, and seems to produce less
1567 blurry results than normal.
1568 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1569
1570 - the rubthrough() method can now render onto images with an alpha
1571 channel.
1572 http://rt.cpan.org/Ticket/Display.html?id=20678
1573
1574 - the read_multi() method now falls back to calling doing a single
1575 image read via the read() method and write_multi() will now fall
1576 back to calling write() if a single image is supplied. This means
1577 you can simply call the read_multi() or write_multi() functions
1578 without having to check if the type is formatted by that method.
1579 http://rt.cpan.org/Ticket/Display.html?id=19457
1580 http://rt.cpan.org/Ticket/Display.html?id=19458
1581
1582 - the GIF loop extension can now be written. If you don't have
1583 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1584 should upgrade.
1585 http://rt.cpan.org/Ticket/Display.html?id=21185
1586
1587 - getscanline() and setscanline() can now read/write palette index
1588 based data from/to the image for paletted images, by setting type to
1589 'index'.
1590 http://rt.cpan.org/Ticket/Display.html?id=20338
1591
1592 - we no longer hassle you to disable GIF support
1593 http://rt.cpan.org/Ticket/Display.html?id=20687
1594
1595 - minor documentation fixes
1596
1597
1598Imager 0.53 - 26 Jul 2006
1599===========
1600
1601This is a bugfix release.
1602
1603Some test code was left in a code path not covered by the test
1604suite. A test was added to cover this code path and the test code was
1605removed.

1608
1609Imager 0.52 - 25 Jul 2006
1610===========
1611
1612This is primarily a feature release, but contains a fair few bug
1613fixes, new features:
1614
1615 - ability to read and write MS Windows ICO and CUR files
1616
1617 - you can now add file format plugins to support new file formats
1618
1619 - add POD coverage tests
1620
1621 - setcolors() and addcolors() now accept color names and so on
1622 instead of requiring Imager::Color objects.
1623 http://rt.cpan.org/Ticket/Display.html?id=20056
1624
1625 - flood_fill() can now fill to a specified border color instead of
1626 just to the area the same color as the seed.
1627 http://rt.cpan.org/Ticket/Display.html?id=19618
1628
1629
1630Bug fixes:
1631
1632 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1633 calculating the advance width.
1634 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1635
1636 - bounding_box for the T1 driver wasn't including leading and
1637 trailing spaces in the bounding box as the other drivers did, it also
1638 produced strange results for empty strings or strings containing only
1639 spaces
1640
1641 - when reading CMYK jpeg images they were being transferred to the
1642 image object as is, producing a four channel image. It only looked ok
1643 due to an old still unfixed Photoshop bug. We now convert from the
1644 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1645 http://rt.cpan.org/Ticket/Display.html?id=20416
1646
1647 - reading a CYMK TIFF would result in a 4 channel image, reading any
1648 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1649 result in an error.
1650 http://rt.cpan.org/Ticket/Display.html?id=20415
1651
1652 - added /usr/local/include to the default include search path, since
1653 we were already searching /usr/local/lib for libraries.
1654
1655And various minor fixes and documentation updates.
1656
1657
1658Imager 0.51 - 23 Apr 2006

1664
1665 - fix mis-processing of the src_maxx and src_maxy parameters of the

1679 output is an in-memeory buffer.
