19===========

21Bug fixes:
71fbe41a
TC
22
23 - previously a transparency enabled GIF write (the default) would
24 always use a GIF89a header even if none of the images were
25 transparent.

46Enhancements:
47
48 - support for giflib 5.0. (5.0.1 and later)
49 https://rt.cpan.org/Ticket/Display.html?id=79029
50 The giflib API Imager uses doesn't have a mechanism to set the
51 header version in 5.0.0.
52
53 - update the GIF library probe code to check for the new giflib 5.0.1
54 EGifSetGifVersion() function, and to check for the giflib 4.2.0
55 uninitialized gif89 bug.
56 https://rt.cpan.org/Ticket/Display.html?id=79679
57 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
58
59 - avoid static variables when capturing IPTC data from JPEG files
60
61 - match Imager::Font;:T1's error message translations to those from
62 later versions of T1Lib.
63
64 - for libtiff versions that support extended warning handlers (3.8.0
65 or later), use them to avoid some global variables.
66
67 - note Image::ExifTool for better metadata support.

82===========
83
ef84bb32 84Bug fixes:
38742a13 85
289d65f4
TC
86 - The size of rotated images is no longer rounded up so aggressively.
87 Added rounding to the linear interpolation done for rotate() and
88 matrix_transform() for 1 and 3 channel 8-bit images.
89 Adjusted the two tranlate matrices used to build the final rotation
90 matrix to use the distance between the outlier pixels rather than
91 the pixel dimensions (ie. dimension-1).
92 With all of this the output of rotate(degrees => 270) on an 8-bit
93 image exactly matches the output of rotate(right => 270).
94 https://rt.cpan.org/Ticket/Display.html?id=77063
95
ef84bb32
TC
96Other changes:
97
98 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
99 internals, those names only matter for the XS interface.
100
101 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
102 the API level compiled into a loadable module such as
103 Imager::File::GIF doesn't match that of Imager. Previously it
104 could be difficult to determine exactly which module was failing to
105 load.
106 https://rt.cpan.org/Ticket/Display.html?id=77173
107
108 - added Imager->check_file_limits() as an interface to the
109 i_int_check_image_file_limits() API.
110
111 - Imager->set_file_limits(reset => 1) now resets the limits to the
112 defaults rather than setting them all to unlimited.
113
114 - wrote a brief security note as Imager::Security
115 https://rt.cpan.org/Ticket/Display.html?id=68910

6f31dd14 117Imager 0.90 - 30 Apr 2012
7c4464f5
TC
118===========
119
120Bug fixes:
121
122 - Imager::Test::is_imaged() attempted to process an "epsilon"
123 parameter but the prototype didn't allow for the extra parameter.
124 Corrected the prototype.
125
29b38678
TC
126 - when downconverting samples (eg. from floating point to 8 bit)
127 Imager now rounds the sample value rather than attempting to
128 allocate input values over output values equally. The old
129 behaviour had the probably surprising effect of converting a
130 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
131 2.
132 This may result in slightly different 8 or 16-bit output images.
133
e2a86bac
TC
134 - BI_BITFIELD BMP images were handled incorrectly, both in
135 incorrectly calculating the space required for the masks and in
136 processing the image data itself.
137 https://rt.cpan.org/Ticket/Display.html?id=76736
138
139 - some odd width BMP BI_RLE4 images use run lengths that run one off
140 the edge of the image. Imager now allows this, discarding the
141 extra column.
142
143 - odd length RLE4 runs in BMP images were decoded incorrectly.
144
82eb0687
TC
145 - pkg-config could sometimes return a library that was in a directory
146 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
147 If no -L is included in the pkg-config library information check if
148 EU::MM can find the library, and if not, search our configured
149 directories and insert that into the library flags.
150 https://rt.cpan.org/Ticket/Display.html?id=75869
151
de50f459
TC
152 - Imager::Probe can now probe for libraries with dependent libraries,
153 common for static linking, eg. libpng requires libz.
154 https://rt.cpan.org/Ticket/Display.html?id=74043
155
156 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
157
158 - added alternative probe configurations that try to link libz, to
159 handle a statically linked libpng.
160 https://rt.cpan.org/Ticket/Display.html?id=74043
161
162 - if a probe includes testcode, Imager::Probe now checks that code as
163 part of the process of checking each configuration rather than as a
164 post test of the found configuration. This allows alternate
165 configurations to be checked if a matching but non-working
166 configuration is found.
167 https://rt.cpan.org/Ticket/Display.html?id=74043
168
9d5ff8a6
TC
169Other changes:
170
171 - when reading or writing images via callbacks, the default callbacks
172 now push an error message indicating that a required callback was
173 called but not supplied.
174 https://rt.cpan.org/Ticket/Display.html?id=76782
175
176 - clarify which callbacks are required for reading and writing TIFF
177 images.
178
179 - improve logging for creation of callback I/O layers.
180
de50f459
TC
181 - a little more documentation for Imager::Probe.
182
594f5933
TC
183 - the i_get_file_background() and i_get_file_backgroundf() APIs now
184 return int to indicate whether the i_background tag was found.
185
1b46057d
TC
186 - PNG rework
187 - improve error reporting
188 - add png_interlace, png_bits tags
189 - read paletted images as paletted images, including transparency
190 - read 1 bit greyscale images as a type suitable for other file
191 handlers to write as bilevel
192 - read 16 bit/sample PNG as 16-bit/sample Imager images
193 - write "bilevel" paletted images as 1 bit grayscale images
194 - write paletted images as paletted images
195 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
196 images
197 - improved metadata support

211 - links in the METHOD INDEX now point at the method documentation
212 rather than the heading you can find them under.
213 https://rt.cpan.org/Ticket/Display.html?id=71495
214
a5919365
TC
215 - Imager (and the bundled dynamic modules) no longer fallback to
216 using DynaLoader if loading via XSLoader fails.
217 For the bundled modules this could hide useful error messages.
218 https://rt.cpan.org/Ticket/Display.html?id=75560
219
335078fc
TC
220 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
221 buffer in the array of allocations, but just stores the filename
222 pointer and line number.

226===========
227
43bef43b
TC
228 - describe how to build libgif etc on OS X in such a way as to be
229 compatible with a fat binary perl (such as the system perl), in
230 README.
231 https://rt.cpan.org/Ticket/Display.html?id=73371
232
69675eef

TC
239 - note that the generator of the apparently non-DFSG-free postscript
240 in MMOne.pfb is a Debian package.
241
02323e69
TC
242 - setsamples() is now a true complement to getsamples() - it can
243 write 8-bit or floating point samples from a scalar or array
244 reference. This adds i_psamp() and i_psampf() to the C level API.
245
246 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
247 changed to make better use of the typemap, but these aren't part of
248 the perl level API anyway. There were no changes to the C level
249 interfaces to these functions.
250
2a27eeff
TC
251 - getpixel() and setpixel() now accept a mix of scalar and array
252 references for the x and y parameters, and unequal array lengths is
253 no longer an error.
254 https://rt.cpan.org/Ticket/Display.html?id=73697

265 - Win32 text output is now done in normal combine mode, the alpha
266 component of the color is now significant.

272 - the getsamples() target parameter was being treated as a hashref

275
2a27eeff
TC
276 - getpixel() and setpixel() now returns an empty list when invalid

298 identify the file type match reality.
299 https://rt.cpan.org/Ticket/Display.html?id=72475
300
301 - read() now uses $FORMATGUESS if it can't determine the file type
302 based on the file header, to match read_multi().
303
304 - re-work and add tests for def_guess_type(). def_guess_type() no
305 longer returns any random file extension as the file type.

366 engine.
367
6e938c74

401
402 - add simple tests for the Imager::Test test_image generators
403
6d5c85a2
TC
404 - io_glue I/O buffering re-work:
405
406 - reorganize io_glue to do it's own buffering by default
407
408 - the unbuffered functions are available as i_io_raw_read() (or
409 raw_read() from perl) etc but are not recommended for typical
410 use.
411
412 - use the new i_io_peekn() when checking for file magic to avoid
413 seek, allowing Imager to detect the file type and read the file
414 from an unseekable stream (for formats that don't use random
415 access)
416
417 - added several new I/O layer API functions.
418
419 - fix the TGA performance problem, most noticably on Win32
420 https://rt.cpan.org/Ticket/Display.html?id=70037
421
422 - TIFF now uses wrapper functions of the correct types to avoid casts
423 https://rt.cpan.org/Ticket/Display.html?id=69912
424
425 - the callback IO object did its own buffering, controlled by the
426 maxbuffer parameter supplied to the read() and write() methods.
427 This buffering has been removed, to avoid redundancy with the
428 common io_glue buffering. This also avoids a bug in that code
429 which could rarely pass a zero length to the read callback and
430 then panic about the result.
431
432 - the callback IO object now tests the result of calling the close
433 callback, which should return true for success.
434
435 - the PNM reader did its own buffering. This buffering has been
436 removed to avoid redundancy with the common io_glue buffering.
437
438 - previously the read handlers for fd and callback I/O layers would
439 call the underlying interface (POSIX read or your supplied callback)
440 until it filled the buffer. It now only makes one call.
441
442 - added public constructors for I/O layer objects (see Imager::IO)
443
444 - all core file handlers now use the i_io_foo() wrappers to gain
445 access to buffered I/O rather than calling the I/O layer
446 callbacks directly.
447
448 - all core file handlers now check for error on close.
449
450 - Backward compatibility: if you hava custom file handlers, you can
451 use i_io_write() etc since they're available as macros in older
452 versions of Imager.
453
454 - eliminate the final remnants of io_glue_commit_types().
455
456 - bump IMAGER_API_VERSION, since the above may break assumptions.
457
458 - removed the long unused i_gen_reader() and i_gen_writer() utility
459 functions.

464The main changes in the release versus 0.84 are:
465
466 - on 64-bit systems, 64-bit types are consistently used for image
467 dimensions and co-ordinated, and for memory block sizes.
468
469 - handle IFD loops in TIFF files correctly. Previously this would
470 lead to an infinite loop.

TC
492 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
493 through TIFF images, since it checks for IFD loops.

519Imager 0.84_01 - 8 Aug 2011
520==============
521
522Development release as a sanity check for the types re-work.
8d14daab
TC
523
524Massive types re-work:
525
526 - the type used internally for pixel co-ordinates and image sizes is
527 now 64-bit on 64-bit platforms (at least sane ones).
528
529 - size_t is now used consistently for memory block sizes.
530
531 - since this changes the binary interface, the Imager API version has
532 been incremented. Any module that uses the API will need to be
533 rebuilt. In most cases that will be enough, but calls to any APIs
534 that take a pointer to image sizes may need source changes.
535
536 - you should be able to create very large images on 64-bit systems,
537 if you have enough memory. Successfully created a 32768 x 49192 x
538 3 channel image, filled with a tiled image and scaled it. The
539 unscaled image was also successfully saved to a JPEG.
540
541 - check the image size before attempting to write BMP, GIF, JPEG,
542 PNG, SGI, TGA, TIFF images.
543
544 - correctly handle reading TGA images over 32767 pixels wide or tall.
545
546Incidental changes:
547
548 - the gif_left and gif_top tags are now clamped to non-negative
549 values when writing a GIF image.
550
551 - removed dead callback read/write code
552
553The default maximum memory size when reading files is now 1G.

585 - writing a paletted image to GIF wouldn't always use the colors

652 - if we see an -rpath (or -R) option in $Config{lddlflags} supply

1200 - moved the imtoc.perl code into Imager::Preprocess

1205 noalpha channels or back.
1206 https://rt.cpan.org/Ticket/Display.html?id=30908
1207
1208 - rubthrough() now falls back to pasting when the source doesn't have
1209 an alpha channel. This effectively treats the source as having a
1210 max alpha channel, the right thing to do.
1211 http://rt.cpan.org/Ticket/Display.html?id=29944

1213 - re-worked most of the area filling code to use a common set of

1216 Rewrote most of the combine modes to match the way the SVG draft
1217 defines them with respect to a translucent source and destination.

1220 similarly.

1262 problem with loading such an image. I haven't been able to find any
1263 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so

1583Imager 0.55 - 16 Dec 2006
1584===========
1585
1586This is primarily a bug fix release.
1587
1588Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1589
1590There is one new feature:
1591
1592 - the Win32 font driver now supports UTF8 (RT 22166)
1593 http://www.cpanforum.com/threads/3276
1594 http://rt.cpan.org/Ticket/Display.html?id=22166
1595
1596Several bugs were fixed:
1597
1598 - the string() method would not output the string "0"
1599 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1600
1601 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1602 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1603
1604 - the gif_disposal and gif_user_input tags weren't being read from
1605 the file correctly
1606 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1607
1608 - gif.c was failing to build under MSVC
1609 http://rt.cpan.org/Ticket/Display.html?id=23922
1610
1611 - in some cases strings passed to the string() method were treated as
1612 terminated by NUL (chr 0)
1613 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1614
1615 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1616 that's the default build name for zlib on Win32.
1617 http://rt.cpan.org/Ticket/Display.html?id=23064
1618
1619 - search $Config{incpath} for headers too, which we should have been
1620 doing all along.
1621
1622Win32 font driver fixes:
1623
1624 - the global descent value from bounding box was the wrong sign
1625 http://www.cpanforum.com/threads/3276
1626
1627 - if the first or last glyph overflowed the left or right side of the
1628 advance width they would be clipped

1630
1631Imager 0.54 - 14 Sep 2006
1632===========
1633
1634This is primarily a feature release:
1635
1636 - a new qtype value 'mixing' has been added to the scale()
1637 method. This is faster than 'normal', slower than 'preview'. This
1638 is based on the method used by pnmscale, and seems to produce less
1639 blurry results than normal.
1640 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1641
1642 - the rubthrough() method can now render onto images with an alpha
1643 channel.
1644 http://rt.cpan.org/Ticket/Display.html?id=20678
1645
1646 - the read_multi() method now falls back to calling doing a single
1647 image read via the read() method and write_multi() will now fall
1648 back to calling write() if a single image is supplied. This means
1649 you can simply call the read_multi() or write_multi() functions
1650 without having to check if the type is formatted by that method.
1651 http://rt.cpan.org/Ticket/Display.html?id=19457
1652 http://rt.cpan.org/Ticket/Display.html?id=19458
1653
1654 - the GIF loop extension can now be written. If you don't have
1655 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1656 should upgrade.
1657 http://rt.cpan.org/Ticket/Display.html?id=21185
1658
1659 - getscanline() and setscanline() can now read/write palette index
1660 based data from/to the image for paletted images, by setting type to
1661 'index'.
1662 http://rt.cpan.org/Ticket/Display.html?id=20338
1663
1664 - we no longer hassle you to disable GIF support
1665 http://rt.cpan.org/Ticket/Display.html?id=20687
1666
1667 - minor documentation fixes
1668
1669
1670Imager 0.53 - 26 Jul 2006
1671===========
1672
1673This is a bugfix release.
1674
1675Some test code was left in a code path not covered by the test
1676suite. A test was added to cover this code path and the test code was
1677removed.

1681Imager 0.52 - 25 Jul 2006
1682===========
1683
1684This is primarily a feature release, but contains a fair few bug
1685fixes, new features:
1686
1687 - ability to read and write MS Windows ICO and CUR files
1688
1689 - you can now add file format plugins to support new file formats
1690
1691 - add POD coverage tests
1692
1693 - setcolors() and addcolors() now accept color names and so on
1694 instead of requiring Imager::Color objects.
1695 http://rt.cpan.org/Ticket/Display.html?id=20056
1696
1697 - flood_fill() can now fill to a specified border color instead of
1698 just to the area the same color as the seed.
1699 http://rt.cpan.org/Ticket/Display.html?id=19618
1700
1701
1702Bug fixes:
1703
1704 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1705 calculating the advance width.
1706 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1707
1708 - bounding_box for the T1 driver wasn't including leading and
1709 trailing spaces in the bounding box as the other drivers did, it also
1710 produced strange results for empty strings or strings containing only
1711 spaces
1712
1713 - when reading CMYK jpeg images they were being transferred to the
1714 image object as is, producing a four channel image. It only looked ok
1715 due to an old still unfixed Photoshop bug. We now convert from the
1716 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1717 http://rt.cpan.org/Ticket/Display.html?id=20416
1718
1719 - reading a CYMK TIFF would result in a 4 channel image, reading any
1720 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1721 result in an error.
1722 http://rt.cpan.org/Ticket/Display.html?id=20415
1723
1724 - added /usr/local/include to the default include search path, since
1725 we were already searching /usr/local/lib for libraries.
1726
1727And various minor fixes and documentation updates.
1728
