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

31

TC
32Other changes:
33
34 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
35 internals, those names only matter for the XS interface.
36
37 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
38 the API level compiled into a loadable module such as
39 Imager::File::GIF doesn't match that of Imager. Previously it
40 could be difficult to determine exactly which module was failing to
41 load.
42 https://rt.cpan.org/Ticket/Display.html?id=77173
43
44 - added Imager->check_file_limits() as an interface to the
45 i_int_check_image_file_limits() API.
46
47 - Imager->set_file_limits(reset => 1) now resets the limits to the
48 defaults rather than setting them all to unlimited.
49
50 - wrote a brief security note as Imager::Security

7c4464f5
TC
54===========
55
56Bug fixes:
57
58 - Imager::Test::is_imaged() attempted to process an "epsilon"
59 parameter but the prototype didn't allow for the extra parameter.
60 Corrected the prototype.
61
29b38678
TC
62 - when downconverting samples (eg. from floating point to 8 bit)
63 Imager now rounds the sample value rather than attempting to
64 allocate input values over output values equally. The old
65 behaviour had the probably surprising effect of converting a
66 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
67 2.
68 This may result in slightly different 8 or 16-bit output images.
69
e2a86bac
TC
70 - BI_BITFIELD BMP images were handled incorrectly, both in
71 incorrectly calculating the space required for the masks and in
72 processing the image data itself.
73 https://rt.cpan.org/Ticket/Display.html?id=76736
74
75 - some odd width BMP BI_RLE4 images use run lengths that run one off
76 the edge of the image. Imager now allows this, discarding the
77 extra column.
78
79 - odd length RLE4 runs in BMP images were decoded incorrectly.
80

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

TC
105Other changes:
106
107 - when reading or writing images via callbacks, the default callbacks
108 now push an error message indicating that a required callback was
109 called but not supplied.
110 https://rt.cpan.org/Ticket/Display.html?id=76782
111
112 - clarify which callbacks are required for reading and writing TIFF
113 images.
114
115 - improve logging for creation of callback I/O layers.
116
de50f459
TC
117 - a little more documentation for Imager::Probe.
118
594f5933

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

122 - PNG rework
123 - improve error reporting
124 - add png_interlace, png_bits tags
125 - read paletted images as paletted images, including transparency
126 - read 1 bit greyscale images as a type suitable for other file
127 handlers to write as bilevel
128 - read 16 bit/sample PNG as 16-bit/sample Imager images
129 - write "bilevel" paletted images as 1 bit grayscale images
130 - write paletted images as paletted images
131 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
132 images
133 - improved metadata support

141 - getpixel(..., type => "float") and the API i_gpixf() have been
142 broken on paletted images since they were implemented.

TC
151 - Imager (and the bundled dynamic modules) no longer fallback to
152 using DynaLoader if loading via XSLoader fails.
153 For the bundled modules this could hide useful error messages.
154 https://rt.cpan.org/Ticket/Display.html?id=75560
155
335078fc
TC
156 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
157 buffer in the array of allocations, but just stores the filename
158 pointer and line number.

161Imager 0.88 - 22 Feb 2012
162===========
163
43bef43b
TC
164 - describe how to build libgif etc on OS X in such a way as to be
165 compatible with a fat binary perl (such as the system perl), in
166 README.
167 https://rt.cpan.org/Ticket/Display.html?id=73371
168

TC
175 - note that the generator of the apparently non-DFSG-free postscript
176 in MMOne.pfb is a Debian package.
177
02323e69
TC
178 - setsamples() is now a true complement to getsamples() - it can
179 write 8-bit or floating point samples from a scalar or array
180 reference. This adds i_psamp() and i_psampf() to the C level API.
181
182 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
183 changed to make better use of the typemap, but these aren't part of
184 the perl level API anyway. There were no changes to the C level
185 interfaces to these functions.
186
2a27eeff
TC
187 - getpixel() and setpixel() now accept a mix of scalar and array
188 references for the x and y parameters, and unequal array lengths is
189 no longer an error.

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

211

234 identify the file type match reality.
235 https://rt.cpan.org/Ticket/Display.html?id=72475
236
237 - read() now uses $FORMATGUESS if it can't determine the file type
238 based on the file header, to match read_multi().
239
240 - re-work and add tests for def_guess_type(). def_guess_type() no
241 longer returns any random file extension as the file type.

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

299 creation.
300
301 - Imager::Font->new now produces better error messages for the T1
302 engine.
303
6e938c74
TC
304 - the font has_chars() method now returns perl's true and false
305 values in list context rather than integers, which should be more
306 efficient.

322
336ce474
TC
323 - we rely on Config.pm's d_vsnprintf as to whether we use
324 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
325 though it only has _ prefixed versions of these. Define our own
326 prefixed names on Win32.

337
338 - add simple tests for the Imager::Test test_image generators
339

TC
340 - io_glue I/O buffering re-work:
341
342 - reorganize io_glue to do it's own buffering by default
343
344 - the unbuffered functions are available as i_io_raw_read() (or
345 raw_read() from perl) etc but are not recommended for typical
346 use.
347
348 - use the new i_io_peekn() when checking for file magic to avoid
349 seek, allowing Imager to detect the file type and read the file
350 from an unseekable stream (for formats that don't use random
351 access)
352
353 - added several new I/O layer API functions.
354
355 - fix the TGA performance problem, most noticably on Win32
356 https://rt.cpan.org/Ticket/Display.html?id=70037
357
358 - TIFF now uses wrapper functions of the correct types to avoid casts
359 https://rt.cpan.org/Ticket/Display.html?id=69912
360
361 - the callback IO object did its own buffering, controlled by the
362 maxbuffer parameter supplied to the read() and write() methods.
363 This buffering has been removed, to avoid redundancy with the
364 common io_glue buffering. This also avoids a bug in that code
365 which could rarely pass a zero length to the read callback and
366 then panic about the result.
367
368 - the callback IO object now tests the result of calling the close
369 callback, which should return true for success.
370
371 - the PNM reader did its own buffering. This buffering has been
372 removed to avoid redundancy with the common io_glue buffering.
373
374 - previously the read handlers for fd and callback I/O layers would
375 call the underlying interface (POSIX read or your supplied callback)
376 until it filled the buffer. It now only makes one call.
377
378 - added public constructors for I/O layer objects (see Imager::IO)
379
380 - all core file handlers now use the i_io_foo() wrappers to gain
381 access to buffered I/O rather than calling the I/O layer
382 callbacks directly.
383
384 - all core file handlers now check for error on close.
385
386 - Backward compatibility: if you hava custom file handlers, you can
387 use i_io_write() etc since they're available as macros in older
388 versions of Imager.
389
390 - eliminate the final remnants of io_glue_commit_types().
391
392 - bump IMAGER_API_VERSION, since the above may break assumptions.
393
394 - removed the long unused i_gen_reader() and i_gen_writer() utility
395 functions.

400The main changes in the release versus 0.84 are:
401
402 - on 64-bit systems, 64-bit types are consistently used for image
403 dimensions and co-ordinated, and for memory block sizes.
404
405 - handle IFD loops in TIFF files correctly. Previously this would
406 lead to an infinite loop.

463 now 64-bit on 64-bit platforms (at least sane ones).
464
465 - size_t is now used consistently for memory block sizes.
466
467 - since this changes the binary interface, the Imager API version has
468 been incremented. Any module that uses the API will need to be
469 rebuilt. In most cases that will be enough, but calls to any APIs
470 that take a pointer to image sizes may need source changes.
471
472 - you should be able to create very large images on 64-bit systems,
473 if you have enough memory. Successfully created a 32768 x 49192 x
474 3 channel image, filled with a tiled image and scaled it. The
475 unscaled image was also successfully saved to a JPEG.
476
477 - check the image size before attempting to write BMP, GIF, JPEG,
478 PNG, SGI, TGA, TIFF images.
479
480 - correctly handle reading TGA images over 32767 pixels wide or tall.
481
482Incidental changes:
483
484 - the gif_left and gif_top tags are now clamped to non-negative
485 values when writing a GIF image.
486
487 - removed dead callback read/write code
488
489The default maximum memory size when reading files is now 1G.

936 - the conv filter now enforces that the sum of the coefficients is
937 non-zero. Also, rather than skipping pixels off the edge off the
938 edge of the image, the closest edge pixel is used. Previously

1136 - moved the imtoc.perl code into Imager::Preprocess

1138 - paste() and rubthrough() now adapt the source image data to the

1141 noalpha channels or back.
1142 https://rt.cpan.org/Ticket/Display.html?id=30908
1143
1144 - rubthrough() now falls back to pasting when the source doesn't have
1145 an alpha channel. This effectively treats the source as having a
1146 max alpha channel, the right thing to do.
1147 http://rt.cpan.org/Ticket/Display.html?id=29944
1148
1149 - re-worked most of the area filling code to use a common set of

1152 Rewrote most of the combine modes to match the way the SVG draft
1153 defines them with respect to a translucent source and destination.

1198 problem with loading such an image. I haven't been able to find any
1199 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1200 I'll match it's behaviour. See issue 114913 in the GIMP's
1201 bugzilla.

1358 - the mask for ICO/CUR images is now applied as an alpha channel to
1359 the returned image. For the old behaviour, supply ico_masked => 0
1360 to read() or read_multi(). This should be less confusing when
1361 using Imager as a general image processor.

1367 indexes outside the range of colors defined by the image's palette.

1374 - to avoid confusion, channels not present in the image are returned as

1377 channels.

1519Imager 0.55 - 16 Dec 2006
1520===========
1521
1522This is primarily a bug fix release.
1523
1524Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1525
1526There is one new feature:
1527
1528 - the Win32 font driver now supports UTF8 (RT 22166)
1529 http://www.cpanforum.com/threads/3276
1530 http://rt.cpan.org/Ticket/Display.html?id=22166
1531
1532Several bugs were fixed:
1533
1534 - the string() method would not output the string "0"
1535 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1536
1537 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1538 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1539
1540 - the gif_disposal and gif_user_input tags weren't being read from
1541 the file correctly
1542 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1543
1544 - gif.c was failing to build under MSVC
1545 http://rt.cpan.org/Ticket/Display.html?id=23922
1546
1547 - in some cases strings passed to the string() method were treated as
1548 terminated by NUL (chr 0)
1549 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1550
1551 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1552 that's the default build name for zlib on Win32.
1553 http://rt.cpan.org/Ticket/Display.html?id=23064
1554
1555 - search $Config{incpath} for headers too, which we should have been
1556 doing all along.
1557
1558Win32 font driver fixes:
1559
1560 - the global descent value from bounding box was the wrong sign
1561 http://www.cpanforum.com/threads/3276
1562
1563 - if the first or last glyph overflowed the left or right side of the
1564 advance width they would be clipped
1565
1566
1567Imager 0.54 - 14 Sep 2006
1568===========
1569
1570This is primarily a feature release:
1571
1572 - a new qtype value 'mixing' has been added to the scale()
1573 method. This is faster than 'normal', slower than 'preview'. This
1574 is based on the method used by pnmscale, and seems to produce less
1575 blurry results than normal.
1576 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1577
1578 - the rubthrough() method can now render onto images with an alpha
1579 channel.
1580 http://rt.cpan.org/Ticket/Display.html?id=20678
1581
1582 - the read_multi() method now falls back to calling doing a single
1583 image read via the read() method and write_multi() will now fall
1584 back to calling write() if a single image is supplied. This means
1585 you can simply call the read_multi() or write_multi() functions
1586 without having to check if the type is formatted by that method.
1587 http://rt.cpan.org/Ticket/Display.html?id=19457
1588 http://rt.cpan.org/Ticket/Display.html?id=19458
1589
1590 - the GIF loop extension can now be written. If you don't have
1591 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1592 should upgrade.
1593 http://rt.cpan.org/Ticket/Display.html?id=21185
1594
1595 - getscanline() and setscanline() can now read/write palette index
1596 based data from/to the image for paletted images, by setting type to
1597 'index'.
1598 http://rt.cpan.org/Ticket/Display.html?id=20338
1599
1600 - we no longer hassle you to disable GIF support
1601 http://rt.cpan.org/Ticket/Display.html?id=20687
1602
1603 - minor documentation fixes
1604
1605
1606Imager 0.53 - 26 Jul 2006
1607===========
1608
1609This is a bugfix release.
1610
1611Some test code was left in a code path not covered by the test
1612suite. A test was added to cover this code path and the test code was
1613removed.

1616
1617Imager 0.52 - 25 Jul 2006
1618===========
1619
1620This is primarily a feature release, but contains a fair few bug
1621fixes, new features:
1622
1623 - ability to read and write MS Windows ICO and CUR files
1624
1625 - you can now add file format plugins to support new file formats
1626
1627 - add POD coverage tests
1628
1629 - setcolors() and addcolors() now accept color names and so on
1630 instead of requiring Imager::Color objects.
1631 http://rt.cpan.org/Ticket/Display.html?id=20056
1632
1633 - flood_fill() can now fill to a specified border color instead of
1634 just to the area the same color as the seed.
1635 http://rt.cpan.org/Ticket/Display.html?id=19618
1636
1637
1638Bug fixes:
1639
1640 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1641 calculating the advance width.
1642 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1643
1644 - bounding_box for the T1 driver wasn't including leading and
1645 trailing spaces in the bounding box as the other drivers did, it also
1646 produced strange results for empty strings or strings containing only
1647 spaces
1648
1649 - when reading CMYK jpeg images they were being transferred to the
1650 image object as is, producing a four channel image. It only looked ok
1651 due to an old still unfixed Photoshop bug. We now convert from the
1652 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1653 http://rt.cpan.org/Ticket/Display.html?id=20416
1654
1655 - reading a CYMK TIFF would result in a 4 channel image, reading any
1656 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1657 result in an error.
1658 http://rt.cpan.org/Ticket/Display.html?id=20415
1659
1660 - added /usr/local/include to the default include search path, since
1661 we were already searching /usr/local/lib for libraries.
1662
1663And various minor fixes and documentation updates.
1664
1665
1666Imager 0.51 - 23 Apr 2006
