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

26Other changes:
27
28 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
29 internals, those names only matter for the XS interface.
30
31 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
32 the API level compiled into a loadable module such as
33 Imager::File::GIF doesn't match that of Imager. Previously it
34 could be difficult to determine exactly which module was failing to
35 load.
36 https://rt.cpan.org/Ticket/Display.html?id=77173
37
38 - added Imager->check_file_limits() as an interface to the
39 i_int_check_image_file_limits() API.
40
41 - Imager->set_file_limits(reset => 1) now resets the limits to the
42 defaults rather than setting them all to unlimited.
43
44 - wrote a brief security note as Imager::Security

48===========
49
50Bug fixes:
51
52 - Imager::Test::is_imaged() attempted to process an "epsilon"
53 parameter but the prototype didn't allow for the extra parameter.
54 Corrected the prototype.
55
29b38678
TC
56 - when downconverting samples (eg. from floating point to 8 bit)
57 Imager now rounds the sample value rather than attempting to
58 allocate input values over output values equally. The old
59 behaviour had the probably surprising effect of converting a
60 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
61 2.
62 This may result in slightly different 8 or 16-bit output images.
63
e2a86bac
TC
64 - BI_BITFIELD BMP images were handled incorrectly, both in
65 incorrectly calculating the space required for the masks and in
66 processing the image data itself.
67 https://rt.cpan.org/Ticket/Display.html?id=76736
68
69 - some odd width BMP BI_RLE4 images use run lengths that run one off
70 the edge of the image. Imager now allows this, discarding the
71 extra column.
72
73 - odd length RLE4 runs in BMP images were decoded incorrectly.
74

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

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

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

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

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

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

205
2a27eeff

206 - getpixel() and setpixel() now returns an empty list when invalid

228 identify the file type match reality.
229 https://rt.cpan.org/Ticket/Display.html?id=72475

231 - read() now uses $FORMATGUESS if it can't determine the file type
232 based on the file header, to match read_multi().
233

296 engine.
297
6e938c74

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

397 dimensions and co-ordinated, and for memory block sizes.
398
399 - handle IFD loops in TIFF files correctly. Previously this would
400 lead to an infinite loop.

452Development release as a sanity check for the types re-work.
8d14daab
TC
453
454Massive types re-work:
455
456 - the type used internally for pixel co-ordinates and image sizes is
457 now 64-bit on 64-bit platforms (at least sane ones).
458
459 - size_t is now used consistently for memory block sizes.
460
461 - since this changes the binary interface, the Imager API version has

466 - you should be able to create very large images on 64-bit systems,
467 if you have enough memory. Successfully created a 32768 x 49192 x
468 3 channel image, filled with a tiled image and scaled it. The
469 unscaled image was also successfully saved to a JPEG.

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

1130 - moved the imtoc.perl code into Imager::Preprocess

1135 noalpha channels or back.
1136 https://rt.cpan.org/Ticket/Display.html?id=30908
1137
1138 - rubthrough() now falls back to pasting when the source doesn't have
1139 an alpha channel. This effectively treats the source as having a
1140 max alpha channel, the right thing to do.
1141 http://rt.cpan.org/Ticket/Display.html?id=29944
1142
1143 - re-worked most of the area filling code to use a common set of

1146 Rewrote most of the combine modes to match the way the SVG draft
1147 defines them with respect to a translucent source and destination.

1191 being set was treated as an opaque pixel, but one user reported a
1192 problem with loading such an image. I haven't been able to find any
1193 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1194 I'll match it's behaviour. See issue 114913 in the GIMP's
1195 bugzilla.

1352 - the mask for ICO/CUR images is now applied as an alpha channel to
1353 the returned image. For the old behaviour, supply ico_masked => 0
1354 to read() or read_multi(). This should be less confusing when
1355 using Imager as a general image processor.

1360 - in some cases it's possible for giflib/libungif to return color
1361 indexes outside the range of colors defined by the image's palette.
1362 We now expand the palette to match the indexes used.

1368 - to avoid confusion, channels not present in the image are returned as
1369 zero by getscanline(). This has no effect on the C level i_glin()
1370 and i_glinf() API functions which continue to not set the unused
1371 channels.

1513Imager 0.55 - 16 Dec 2006
1514===========
1515
1516This is primarily a bug fix release.
1517
1518Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1519
1520There is one new feature:
1521
1522 - the Win32 font driver now supports UTF8 (RT 22166)
1523 http://www.cpanforum.com/threads/3276
1524 http://rt.cpan.org/Ticket/Display.html?id=22166
1525
1526Several bugs were fixed:
1527
1528 - the string() method would not output the string "0"
1529 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1530
1531 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1532 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1533
1534 - the gif_disposal and gif_user_input tags weren't being read from
1535 the file correctly
1536 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1537
1538 - gif.c was failing to build under MSVC
1539 http://rt.cpan.org/Ticket/Display.html?id=23922
1540
1541 - in some cases strings passed to the string() method were treated as
1542 terminated by NUL (chr 0)
1543 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1544
1545 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1546 that's the default build name for zlib on Win32.
1547 http://rt.cpan.org/Ticket/Display.html?id=23064
1548
1549 - search $Config{incpath} for headers too, which we should have been
1550 doing all along.
1551
1552Win32 font driver fixes:
1553
1554 - the global descent value from bounding box was the wrong sign
1555 http://www.cpanforum.com/threads/3276
1556
1557 - if the first or last glyph overflowed the left or right side of the
1558 advance width they would be clipped

1560
1561Imager 0.54 - 14 Sep 2006
1562===========
1563
1564This is primarily a feature release:
1565
1566 - a new qtype value 'mixing' has been added to the scale()
1567 method. This is faster than 'normal', slower than 'preview'. This
1568 is based on the method used by pnmscale, and seems to produce less
1569 blurry results than normal.
1570 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1571
1572 - the rubthrough() method can now render onto images with an alpha
1573 channel.
1574 http://rt.cpan.org/Ticket/Display.html?id=20678
1575
1576 - the read_multi() method now falls back to calling doing a single
1577 image read via the read() method and write_multi() will now fall
1578 back to calling write() if a single image is supplied. This means
1579 you can simply call the read_multi() or write_multi() functions
1580 without having to check if the type is formatted by that method.
1581 http://rt.cpan.org/Ticket/Display.html?id=19457
1582 http://rt.cpan.org/Ticket/Display.html?id=19458
1583
1584 - the GIF loop extension can now be written. If you don't have
1585 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1586 should upgrade.
1587 http://rt.cpan.org/Ticket/Display.html?id=21185
1588
1589 - getscanline() and setscanline() can now read/write palette index
1590 based data from/to the image for paletted images, by setting type to
1591 'index'.
1592 http://rt.cpan.org/Ticket/Display.html?id=20338
1593
1594 - we no longer hassle you to disable GIF support
1595 http://rt.cpan.org/Ticket/Display.html?id=20687
1596
1597 - minor documentation fixes
1598
1599
1600Imager 0.53 - 26 Jul 2006
1601===========
1602
1603This is a bugfix release.
1604
1605Some test code was left in a code path not covered by the test
1606suite. A test was added to cover this code path and the test code was
1607removed.

1611Imager 0.52 - 25 Jul 2006
1612===========
1613
1614This is primarily a feature release, but contains a fair few bug
1615fixes, new features:
1616
1617 - ability to read and write MS Windows ICO and CUR files
1618
1619 - you can now add file format plugins to support new file formats
1620
1621 - add POD coverage tests
1622
1623 - setcolors() and addcolors() now accept color names and so on
1624 instead of requiring Imager::Color objects.
1625 http://rt.cpan.org/Ticket/Display.html?id=20056
1626
1627 - flood_fill() can now fill to a specified border color instead of
1628 just to the area the same color as the seed.
1629 http://rt.cpan.org/Ticket/Display.html?id=19618
1630
1631
1632Bug fixes:
1633
1634 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1635 calculating the advance width.
1636 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1637
1638 - bounding_box for the T1 driver wasn't including leading and
1639 trailing spaces in the bounding box as the other drivers did, it also
1640 produced strange results for empty strings or strings containing only
1641 spaces
1642
1643 - when reading CMYK jpeg images they were being transferred to the
1644 image object as is, producing a four channel image. It only looked ok
1645 due to an old still unfixed Photoshop bug. We now convert from the
1646 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1647 http://rt.cpan.org/Ticket/Display.html?id=20416
1648
1649 - reading a CYMK TIFF would result in a 4 channel image, reading any
1650 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1651 result in an error.
1652 http://rt.cpan.org/Ticket/Display.html?id=20415
1653
1654 - added /usr/local/include to the default include search path, since
1655 we were already searching /usr/local/lib for libraries.
1656
1657And various minor fixes and documentation updates.
1658
1659
1660Imager 0.51 - 23 Apr 2006
