TC
16
17 - previously a transparency enabled GIF write (the default) would
18 always use a GIF89a header even if none of the images were
19 transparent.

40Enhancements:
41
42 - support for giflib 5.0. (5.0.1 and later)
43 https://rt.cpan.org/Ticket/Display.html?id=79029
44 The giflib API Imager uses doesn't have a mechanism to set the
45 header version in 5.0.0.
46
47 - update the GIF library probe code to check for the new giflib 5.0.1
48 EGifSetGifVersion() function, and to check for the giflib 4.2.0
49 uninitialized gif89 bug.
50 https://rt.cpan.org/Ticket/Display.html?id=79679
51 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
52
53 - avoid static variables when capturing IPTC data from JPEG files
54
55 - match Imager::Font;:T1's error message translations to those from
56 later versions of T1Lib.
57
58 - for libtiff versions that support extended warning handlers (3.8.0
59 or later), use them to avoid some global variables.
60
61 - note Image::ExifTool for better metadata support.

ef84bb32 78Bug fixes:
38742a13 79
289d65f4
TC
80 - The size of rotated images is no longer rounded up so aggressively.
81 Added rounding to the linear interpolation done for rotate() and
82 matrix_transform() for 1 and 3 channel 8-bit images.
83 Adjusted the two tranlate matrices used to build the final rotation
84 matrix to use the distance between the outlier pixels rather than
85 the pixel dimensions (ie. dimension-1).
86 With all of this the output of rotate(degrees => 270) on an 8-bit
87 image exactly matches the output of rotate(right => 270).
88 https://rt.cpan.org/Ticket/Display.html?id=77063
89
ef84bb32
TC
90Other changes:
91
92 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
93 internals, those names only matter for the XS interface.
94
95 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
96 the API level compiled into a loadable module such as
97 Imager::File::GIF doesn't match that of Imager. Previously it
98 could be difficult to determine exactly which module was failing to
99 load.
100 https://rt.cpan.org/Ticket/Display.html?id=77173
101
102 - added Imager->check_file_limits() as an interface to the
103 i_int_check_image_file_limits() API.
104
105 - Imager->set_file_limits(reset => 1) now resets the limits to the
106 defaults rather than setting them all to unlimited.
107
108 - wrote a brief security note as Imager::Security
109 https://rt.cpan.org/Ticket/Display.html?id=68910

6f31dd14 111Imager 0.90 - 30 Apr 2012
7c4464f5
TC
112===========
113
114Bug fixes:
115
116 - Imager::Test::is_imaged() attempted to process an "epsilon"
117 parameter but the prototype didn't allow for the extra parameter.
118 Corrected the prototype.
119
29b38678
TC
120 - when downconverting samples (eg. from floating point to 8 bit)
121 Imager now rounds the sample value rather than attempting to
122 allocate input values over output values equally. The old
123 behaviour had the probably surprising effect of converting a
124 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
125 2.
126 This may result in slightly different 8 or 16-bit output images.
127
e2a86bac
TC
128 - BI_BITFIELD BMP images were handled incorrectly, both in
129 incorrectly calculating the space required for the masks and in
130 processing the image data itself.
131 https://rt.cpan.org/Ticket/Display.html?id=76736
132
133 - some odd width BMP BI_RLE4 images use run lengths that run one off
134 the edge of the image. Imager now allows this, discarding the
135 extra column.
136
137 - odd length RLE4 runs in BMP images were decoded incorrectly.
138
82eb0687
TC
139 - pkg-config could sometimes return a library that was in a directory
140 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
141 If no -L is included in the pkg-config library information check if
142 EU::MM can find the library, and if not, search our configured
143 directories and insert that into the library flags.
144 https://rt.cpan.org/Ticket/Display.html?id=75869
145
de50f459
TC
146 - Imager::Probe can now probe for libraries with dependent libraries,
147 common for static linking, eg. libpng requires libz.
148 https://rt.cpan.org/Ticket/Display.html?id=74043
149
150 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
151
152 - added alternative probe configurations that try to link libz, to
153 handle a statically linked libpng.
154 https://rt.cpan.org/Ticket/Display.html?id=74043
155
156 - if a probe includes testcode, Imager::Probe now checks that code as
157 part of the process of checking each configuration rather than as a
158 post test of the found configuration. This allows alternate
159 configurations to be checked if a matching but non-working
160 configuration is found.
161 https://rt.cpan.org/Ticket/Display.html?id=74043
162
9d5ff8a6
TC
163Other changes:
164
165 - when reading or writing images via callbacks, the default callbacks
166 now push an error message indicating that a required callback was
167 called but not supplied.
168 https://rt.cpan.org/Ticket/Display.html?id=76782
169
170 - clarify which callbacks are required for reading and writing TIFF
171 images.
172
173 - improve logging for creation of callback I/O layers.
174
de50f459
TC
175 - a little more documentation for Imager::Probe.
176
594f5933
TC
177 - the i_get_file_background() and i_get_file_backgroundf() APIs now
178 return int to indicate whether the i_background tag was found.
179
1b46057d
TC
180 - PNG rework
181 - improve error reporting
182 - add png_interlace, png_bits tags
183 - read paletted images as paletted images, including transparency
184 - read 1 bit greyscale images as a type suitable for other file
185 handlers to write as bilevel
186 - read 16 bit/sample PNG as 16-bit/sample Imager images
187 - write "bilevel" paletted images as 1 bit grayscale images
188 - write paletted images as paletted images
189 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
190 images
191 - improved metadata support

205 - links in the METHOD INDEX now point at the method documentation
206 rather than the heading you can find them under.
207 https://rt.cpan.org/Ticket/Display.html?id=71495
208
a5919365
TC
209 - Imager (and the bundled dynamic modules) no longer fallback to
210 using DynaLoader if loading via XSLoader fails.
211 For the bundled modules this could hide useful error messages.
212 https://rt.cpan.org/Ticket/Display.html?id=75560
213
335078fc
TC
214 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
215 buffer in the array of allocations, but just stores the filename
216 pointer and line number.

220===========
221
43bef43b
TC
222 - describe how to build libgif etc on OS X in such a way as to be
223 compatible with a fat binary perl (such as the system perl), in
224 README.
225 https://rt.cpan.org/Ticket/Display.html?id=73371
226

TC
233 - note that the generator of the apparently non-DFSG-free postscript
234 in MMOne.pfb is a Debian package.
235
02323e69
TC
236 - setsamples() is now a true complement to getsamples() - it can
237 write 8-bit or floating point samples from a scalar or array
238 reference. This adds i_psamp() and i_psampf() to the C level API.
239
240 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
241 changed to make better use of the typemap, but these aren't part of
242 the perl level API anyway. There were no changes to the C level
243 interfaces to these functions.
244
2a27eeff
TC
245 - getpixel() and setpixel() now accept a mix of scalar and array
246 references for the x and y parameters, and unequal array lengths is
247 no longer an error.

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

264 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
265
7640e3bb
TC
266 - the getsamples() target parameter was being treated as a hashref
267 when it's meant to be an array reference.

269
2a27eeff
TC
270 - getpixel() and setpixel() now returns an empty list when invalid
271 parameters are supplied.
272 Invalid values for type now result in an error for getpixel().

291 - make the error message from read() or read_multi() when they can't
292 identify the file type match reality.
293 https://rt.cpan.org/Ticket/Display.html?id=72475
294
295 - read() now uses $FORMATGUESS if it can't determine the file type
296 based on the file header, to match read_multi().
297
298 - re-work and add tests for def_guess_type(). def_guess_type() no
299 longer returns any random file extension as the file type.

TC
395
396 - add simple tests for the Imager::Test test_image generators
397
6d5c85a2
TC
398 - io_glue I/O buffering re-work:
399
400 - reorganize io_glue to do it's own buffering by default
401
402 - the unbuffered functions are available as i_io_raw_read() (or
403 raw_read() from perl) etc but are not recommended for typical
404 use.
405
406 - use the new i_io_peekn() when checking for file magic to avoid
407 seek, allowing Imager to detect the file type and read the file
408 from an unseekable stream (for formats that don't use random
409 access)
410
411 - added several new I/O layer API functions.
412
413 - fix the TGA performance problem, most noticably on Win32
414 https://rt.cpan.org/Ticket/Display.html?id=70037
415
416 - TIFF now uses wrapper functions of the correct types to avoid casts
417 https://rt.cpan.org/Ticket/Display.html?id=69912
418
419 - the callback IO object did its own buffering, controlled by the
420 maxbuffer parameter supplied to the read() and write() methods.
421 This buffering has been removed, to avoid redundancy with the
422 common io_glue buffering. This also avoids a bug in that code
423 which could rarely pass a zero length to the read callback and
424 then panic about the result.
425
426 - the callback IO object now tests the result of calling the close
427 callback, which should return true for success.
428
429 - the PNM reader did its own buffering. This buffering has been
430 removed to avoid redundancy with the common io_glue buffering.
431
432 - previously the read handlers for fd and callback I/O layers would
433 call the underlying interface (POSIX read or your supplied callback)
434 until it filled the buffer. It now only makes one call.
435
436 - added public constructors for I/O layer objects (see Imager::IO)
437
438 - all core file handlers now use the i_io_foo() wrappers to gain
439 access to buffered I/O rather than calling the I/O layer
440 callbacks directly.
441
442 - all core file handlers now check for error on close.
443
444 - Backward compatibility: if you hava custom file handlers, you can
445 use i_io_write() etc since they're available as macros in older
446 versions of Imager.
447
448 - eliminate the final remnants of io_glue_commit_types().
449
450 - bump IMAGER_API_VERSION, since the above may break assumptions.
451
452 - removed the long unused i_gen_reader() and i_gen_writer() utility
453 functions.

458The main changes in the release versus 0.84 are:
459
460 - on 64-bit systems, 64-bit types are consistently used for image

514==============
515
516Development release as a sanity check for the types re-work.
8d14daab
TC
517
518Massive types re-work:
519
520 - the type used internally for pixel co-ordinates and image sizes is
521 now 64-bit on 64-bit platforms (at least sane ones).
522
523 - size_t is now used consistently for memory block sizes.
524
525 - since this changes the binary interface, the Imager API version has
526 been incremented. Any module that uses the API will need to be
527 rebuilt. In most cases that will be enough, but calls to any APIs
528 that take a pointer to image sizes may need source changes.
529
530 - you should be able to create very large images on 64-bit systems,
531 if you have enough memory. Successfully created a 32768 x 49192 x
532 3 channel image, filled with a tiled image and scaled it. The
533 unscaled image was also successfully saved to a JPEG.
534
535 - check the image size before attempting to write BMP, GIF, JPEG,
536 PNG, SGI, TGA, TIFF images.
537
538 - correctly handle reading TGA images over 32767 pixels wide or tall.
539
540Incidental changes:
541
542 - the gif_left and gif_top tags are now clamped to non-negative
543 values when writing a GIF image.
544
545 - removed dead callback read/write code
546
547The default maximum memory size when reading files is now 1G.

1194 - moved the imtoc.perl code into Imager::Preprocess

1199 noalpha channels or back.
1200 https://rt.cpan.org/Ticket/Display.html?id=30908
1201
1202 - rubthrough() now falls back to pasting when the source doesn't have
1203 an alpha channel. This effectively treats the source as having a
1204 max alpha channel, the right thing to do.
1205 http://rt.cpan.org/Ticket/Display.html?id=29944

1210 Rewrote most of the combine modes to match the way the SVG draft
1211 defines them with respect to a translucent source and destination.

1256 problem with loading such an image. I haven't been able to find any
1257 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1258 I'll match it's behaviour. See issue 114913 in the GIMP's

1577Imager 0.55 - 16 Dec 2006
1578===========
1579
1580This is primarily a bug fix release.
1581
1582Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1583
1584There is one new feature:
1585
1586 - the Win32 font driver now supports UTF8 (RT 22166)
1587 http://www.cpanforum.com/threads/3276
1588 http://rt.cpan.org/Ticket/Display.html?id=22166
1589
1590Several bugs were fixed:
1591
1592 - the string() method would not output the string "0"
1593 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1594
1595 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1596 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1597
1598 - the gif_disposal and gif_user_input tags weren't being read from
1599 the file correctly
1600 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1601
1602 - gif.c was failing to build under MSVC
1603 http://rt.cpan.org/Ticket/Display.html?id=23922
1604
1605 - in some cases strings passed to the string() method were treated as
1606 terminated by NUL (chr 0)
1607 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1608
1609 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1610 that's the default build name for zlib on Win32.
1611 http://rt.cpan.org/Ticket/Display.html?id=23064
1612
1613 - search $Config{incpath} for headers too, which we should have been
1614 doing all along.
1615
1616Win32 font driver fixes:
1617
1618 - the global descent value from bounding box was the wrong sign
1619 http://www.cpanforum.com/threads/3276
1620
1621 - if the first or last glyph overflowed the left or right side of the
1622 advance width they would be clipped
1623
1624
1625Imager 0.54 - 14 Sep 2006
1626===========
1627
1628This is primarily a feature release:
1629
1630 - a new qtype value 'mixing' has been added to the scale()
1631 method. This is faster than 'normal', slower than 'preview'. This
1632 is based on the method used by pnmscale, and seems to produce less
1633 blurry results than normal.
1634 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1635
1636 - the rubthrough() method can now render onto images with an alpha
1637 channel.
1638 http://rt.cpan.org/Ticket/Display.html?id=20678
1639
1640 - the read_multi() method now falls back to calling doing a single
1641 image read via the read() method and write_multi() will now fall
1642 back to calling write() if a single image is supplied. This means
1643 you can simply call the read_multi() or write_multi() functions
1644 without having to check if the type is formatted by that method.
1645 http://rt.cpan.org/Ticket/Display.html?id=19457
1646 http://rt.cpan.org/Ticket/Display.html?id=19458
1647
1648 - the GIF loop extension can now be written. If you don't have
1649 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1650 should upgrade.
1651 http://rt.cpan.org/Ticket/Display.html?id=21185
1652
1653 - getscanline() and setscanline() can now read/write palette index
1654 based data from/to the image for paletted images, by setting type to
1655 'index'.
1656 http://rt.cpan.org/Ticket/Display.html?id=20338
1657
1658 - we no longer hassle you to disable GIF support
1659 http://rt.cpan.org/Ticket/Display.html?id=20687
1660
1661 - minor documentation fixes
1662
1663
1664Imager 0.53 - 26 Jul 2006
1665===========
1666
1667This is a bugfix release.
1668
1669Some test code was left in a code path not covered by the test
1670suite. A test was added to cover this code path and the test code was
1671removed.

1675Imager 0.52 - 25 Jul 2006
1676===========
1677
1678This is primarily a feature release, but contains a fair few bug
1679fixes, new features:
1680
1681 - ability to read and write MS Windows ICO and CUR files
1682
1683 - you can now add file format plugins to support new file formats
1684
1685 - add POD coverage tests
1686
1687 - setcolors() and addcolors() now accept color names and so on
1688 instead of requiring Imager::Color objects.
1689 http://rt.cpan.org/Ticket/Display.html?id=20056
1690
1691 - flood_fill() can now fill to a specified border color instead of
1692 just to the area the same color as the seed.
1693 http://rt.cpan.org/Ticket/Display.html?id=19618
1694
1695
1696Bug fixes:
1697
1698 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1699 calculating the advance width.
1700 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1701
1702 - bounding_box for the T1 driver wasn't including leading and
1703 trailing spaces in the bounding box as the other drivers did, it also
1704 produced strange results for empty strings or strings containing only
1705 spaces
1706
1707 - when reading CMYK jpeg images they were being transferred to the
1708 image object as is, producing a four channel image. It only looked ok
1709 due to an old still unfixed Photoshop bug. We now convert from the
1710 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1711 http://rt.cpan.org/Ticket/Display.html?id=20416
1712
1713 - reading a CYMK TIFF would result in a 4 channel image, reading any
1714 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1715 result in an error.
1716 http://rt.cpan.org/Ticket/Display.html?id=20415
1717
1718 - added /usr/local/include to the default include search path, since
1719 we were already searching /usr/local/lib for libraries.
1720
1721And various minor fixes and documentation updates.
1722
1723
1724Imager 0.51 - 23 Apr 2006
