TC
31
32 - previously a transparency enabled GIF write (the default) would
33 always use a GIF89a header even if none of the images were
34 transparent.

55Enhancements:
56
57 - support for giflib 5.0. (5.0.1 and later)
58 https://rt.cpan.org/Ticket/Display.html?id=79029
59 The giflib API Imager uses doesn't have a mechanism to set the
60 header version in 5.0.0.
61
62 - update the GIF library probe code to check for the new giflib 5.0.1
63 EGifSetGifVersion() function, and to check for the giflib 4.2.0
64 uninitialized gif89 bug.
65 https://rt.cpan.org/Ticket/Display.html?id=79679
66 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
67
68 - avoid static variables when capturing IPTC data from JPEG files
69
70 - match Imager::Font;:T1's error message translations to those from
71 later versions of T1Lib.
72
73 - for libtiff versions that support extended warning handlers (3.8.0
74 or later), use them to avoid some global variables.
75
76 - note Image::ExifTool for better metadata support.

ef84bb32 93Bug fixes:
38742a13 94
289d65f4
TC
95 - The size of rotated images is no longer rounded up so aggressively.
96 Added rounding to the linear interpolation done for rotate() and
97 matrix_transform() for 1 and 3 channel 8-bit images.
98 Adjusted the two tranlate matrices used to build the final rotation
99 matrix to use the distance between the outlier pixels rather than
100 the pixel dimensions (ie. dimension-1).
101 With all of this the output of rotate(degrees => 270) on an 8-bit
102 image exactly matches the output of rotate(right => 270).
103 https://rt.cpan.org/Ticket/Display.html?id=77063
104
ef84bb32
TC
105Other changes:
106
107 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
108 internals, those names only matter for the XS interface.
109
110 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
111 the API level compiled into a loadable module such as
112 Imager::File::GIF doesn't match that of Imager. Previously it
113 could be difficult to determine exactly which module was failing to
114 load.
115 https://rt.cpan.org/Ticket/Display.html?id=77173
116
117 - added Imager->check_file_limits() as an interface to the
118 i_int_check_image_file_limits() API.
119
120 - Imager->set_file_limits(reset => 1) now resets the limits to the
121 defaults rather than setting them all to unlimited.
122
123 - wrote a brief security note as Imager::Security

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

TC
195 - PNG rework
196 - improve error reporting
197 - add png_interlace, png_bits tags
198 - read paletted images as paletted images, including transparency
199 - read 1 bit greyscale images as a type suitable for other file
200 handlers to write as bilevel
201 - read 16 bit/sample PNG as 16-bit/sample Imager images
202 - write "bilevel" paletted images as 1 bit grayscale images
203 - write paletted images as paletted images
204 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
205 images
206 - improved metadata support

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

223
a5919365
TC
224 - Imager (and the bundled dynamic modules) no longer fallback to
225 using DynaLoader if loading via XSLoader fails.
226 For the bundled modules this could hide useful error messages.
227 https://rt.cpan.org/Ticket/Display.html?id=75560
228
335078fc
TC
229 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
230 buffer in the array of allocations, but just stores the filename
231 pointer and line number.

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

248 - note that the generator of the apparently non-DFSG-free postscript
249 in MMOne.pfb is a Debian package.
250
02323e69
TC
251 - setsamples() is now a true complement to getsamples() - it can
252 write 8-bit or floating point samples from a scalar or array
253 reference. This adds i_psamp() and i_psampf() to the C level API.
254
255 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
256 changed to make better use of the typemap, but these aren't part of
257 the perl level API anyway. There were no changes to the C level
258 interfaces to these functions.
259
2a27eeff
TC
260 - getpixel() and setpixel() now accept a mix of scalar and array
261 references for the x and y parameters, and unequal array lengths is
262 no longer an error.

284

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

307 identify the file type match reality.
308 https://rt.cpan.org/Ticket/Display.html?id=72475
309
310 - read() now uses $FORMATGUESS if it can't determine the file type
311 based on the file header, to match read_multi().
312

TC
410
411 - add simple tests for the Imager::Test test_image generators
412
6d5c85a2
TC
413 - io_glue I/O buffering re-work:
414
415 - reorganize io_glue to do it's own buffering by default
416
417 - the unbuffered functions are available as i_io_raw_read() (or
418 raw_read() from perl) etc but are not recommended for typical
419 use.
420
421 - use the new i_io_peekn() when checking for file magic to avoid
422 seek, allowing Imager to detect the file type and read the file
423 from an unseekable stream (for formats that don't use random
424 access)
425
426 - added several new I/O layer API functions.
427
428 - fix the TGA performance problem, most noticably on Win32
429 https://rt.cpan.org/Ticket/Display.html?id=70037
430
431 - TIFF now uses wrapper functions of the correct types to avoid casts
432 https://rt.cpan.org/Ticket/Display.html?id=69912
433
434 - the callback IO object did its own buffering, controlled by the
435 maxbuffer parameter supplied to the read() and write() methods.
436 This buffering has been removed, to avoid redundancy with the
437 common io_glue buffering. This also avoids a bug in that code
438 which could rarely pass a zero length to the read callback and
439 then panic about the result.
440
441 - the callback IO object now tests the result of calling the close
442 callback, which should return true for success.
443
444 - the PNM reader did its own buffering. This buffering has been
445 removed to avoid redundancy with the common io_glue buffering.
446
447 - previously the read handlers for fd and callback I/O layers would
448 call the underlying interface (POSIX read or your supplied callback)
449 until it filled the buffer. It now only makes one call.
450
451 - added public constructors for I/O layer objects (see Imager::IO)
452
453 - all core file handlers now use the i_io_foo() wrappers to gain
454 access to buffered I/O rather than calling the I/O layer
455 callbacks directly.
456
457 - all core file handlers now check for error on close.
458
459 - Backward compatibility: if you hava custom file handlers, you can
460 use i_io_write() etc since they're available as macros in older
461 versions of Imager.
462
463 - eliminate the final remnants of io_glue_commit_types().
464
465 - bump IMAGER_API_VERSION, since the above may break assumptions.
466
467 - removed the long unused i_gen_reader() and i_gen_writer() utility
468 functions.

TC
471===========
472
0c647c9a
TC
473The main changes in the release versus 0.84 are:
474
475 - on 64-bit systems, 64-bit types are consistently used for image
476 dimensions and co-ordinated, and for memory block sizes.
477
478 - handle IFD loops in TIFF files correctly. Previously this would
479 lead to an infinite loop.

528Imager 0.84_01 - 8 Aug 2011
529==============
530
531Development release as a sanity check for the types re-work.
8d14daab
TC
532
533Massive types re-work:
534
535 - the type used internally for pixel co-ordinates and image sizes is
536 now 64-bit on 64-bit platforms (at least sane ones).
537
538 - size_t is now used consistently for memory block sizes.
539
540 - since this changes the binary interface, the Imager API version has
541 been incremented. Any module that uses the API will need to be
542 rebuilt. In most cases that will be enough, but calls to any APIs
543 that take a pointer to image sizes may need source changes.
544
545 - you should be able to create very large images on 64-bit systems,
546 if you have enough memory. Successfully created a 32768 x 49192 x
547 3 channel image, filled with a tiled image and scaled it. The
548 unscaled image was also successfully saved to a JPEG.
549
550 - check the image size before attempting to write BMP, GIF, JPEG,
551 PNG, SGI, TGA, TIFF images.
552
553 - correctly handle reading TGA images over 32767 pixels wide or tall.
554
555Incidental changes:
556
557 - the gif_left and gif_top tags are now clamped to non-negative
558 values when writing a GIF image.
559
560 - removed dead callback read/write code
561
562The default maximum memory size when reading files is now 1G.

1216
1217 - rubthrough() now falls back to pasting when the source doesn't have
1218 an alpha channel. This effectively treats the source as having a
1219 max alpha channel, the right thing to do.

1226 defines them with respect to a translucent source and destination.

1271 problem with loading such an image. I haven't been able to find any
1272 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1273 I'll match it's behaviour. See issue 114913 in the GIMP's

1592Imager 0.55 - 16 Dec 2006
1593===========
1594
1595This is primarily a bug fix release.
1596
1597Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1598
1599There is one new feature:
1600
1601 - the Win32 font driver now supports UTF8 (RT 22166)
1602 http://www.cpanforum.com/threads/3276
1603 http://rt.cpan.org/Ticket/Display.html?id=22166
1604
1605Several bugs were fixed:
1606
1607 - the string() method would not output the string "0"
1608 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1609
1610 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1611 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1612
1613 - the gif_disposal and gif_user_input tags weren't being read from
1614 the file correctly
1615 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1616
1617 - gif.c was failing to build under MSVC
1618 http://rt.cpan.org/Ticket/Display.html?id=23922
1619
1620 - in some cases strings passed to the string() method were treated as
1621 terminated by NUL (chr 0)
1622 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1623
1624 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1625 that's the default build name for zlib on Win32.
1626 http://rt.cpan.org/Ticket/Display.html?id=23064
1627
1628 - search $Config{incpath} for headers too, which we should have been
1629 doing all along.
1630
1631Win32 font driver fixes:
1632
1633 - the global descent value from bounding box was the wrong sign
1634 http://www.cpanforum.com/threads/3276
1635
1636 - if the first or last glyph overflowed the left or right side of the
1637 advance width they would be clipped
1638
1639
1640Imager 0.54 - 14 Sep 2006
1641===========
1642
1643This is primarily a feature release:
1644
1645 - a new qtype value 'mixing' has been added to the scale()
1646 method. This is faster than 'normal', slower than 'preview'. This
1647 is based on the method used by pnmscale, and seems to produce less
1648 blurry results than normal.
1649 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1650
1651 - the rubthrough() method can now render onto images with an alpha
1652 channel.
1653 http://rt.cpan.org/Ticket/Display.html?id=20678
1654
1655 - the read_multi() method now falls back to calling doing a single
1656 image read via the read() method and write_multi() will now fall
1657 back to calling write() if a single image is supplied. This means
1658 you can simply call the read_multi() or write_multi() functions
1659 without having to check if the type is formatted by that method.
1660 http://rt.cpan.org/Ticket/Display.html?id=19457
1661 http://rt.cpan.org/Ticket/Display.html?id=19458
1662
1663 - the GIF loop extension can now be written. If you don't have
1664 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1665 should upgrade.
1666 http://rt.cpan.org/Ticket/Display.html?id=21185
1667
1668 - getscanline() and setscanline() can now read/write palette index
1669 based data from/to the image for paletted images, by setting type to
1670 'index'.
1671 http://rt.cpan.org/Ticket/Display.html?id=20338
1672
1673 - we no longer hassle you to disable GIF support
1674 http://rt.cpan.org/Ticket/Display.html?id=20687
1675
1676 - minor documentation fixes
1677
1678
1679Imager 0.53 - 26 Jul 2006
1680===========
1681
1682This is a bugfix release.
1683
1684Some test code was left in a code path not covered by the test
1685suite. A test was added to cover this code path and the test code was
1686removed.

1690Imager 0.52 - 25 Jul 2006
1691===========
1692
1693This is primarily a feature release, but contains a fair few bug
1694fixes, new features:
1695
1696 - ability to read and write MS Windows ICO and CUR files
1697
1698 - you can now add file format plugins to support new file formats
1699
1700 - add POD coverage tests
1701
1702 - setcolors() and addcolors() now accept color names and so on
1703 instead of requiring Imager::Color objects.
1704 http://rt.cpan.org/Ticket/Display.html?id=20056
1705
1706 - flood_fill() can now fill to a specified border color instead of
1707 just to the area the same color as the seed.
1708 http://rt.cpan.org/Ticket/Display.html?id=19618
1709
1710
1711Bug fixes:
1712
1713 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1714 calculating the advance width.
1715 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1716
1717 - bounding_box for the T1 driver wasn't including leading and
1718 trailing spaces in the bounding box as the other drivers did, it also
1719 produced strange results for empty strings or strings containing only
1720 spaces
1721
1722 - when reading CMYK jpeg images they were being transferred to the
1723 image object as is, producing a four channel image. It only looked ok
1724 due to an old still unfixed Photoshop bug. We now convert from the
1725 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1726 http://rt.cpan.org/Ticket/Display.html?id=20416
1727
1728 - reading a CYMK TIFF would result in a 4 channel image, reading any
1729 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1730 result in an error.
1731 http://rt.cpan.org/Ticket/Display.html?id=20415
1732
1733 - added /usr/local/include to the default include search path, since
1734 we were already searching /usr/local/lib for libraries.
1735
1736And various minor fixes and documentation updates.
1737
1738
1739Imager 0.51 - 23 Apr 2006
