36Bug fixes:
71fbe41a
TC
37
38 - previously a transparency enabled GIF write (the default) would
39 always use a GIF89a header even if none of the images were
40 transparent.

TC
42 - previously the probe step for freetype-config would fail on cygwin

45 https://rt.cpan.org/Ticket/Display.html?id=79922
46
47 - remove the 16-bit/sample limitation from the documentation for
48 setsamples(), it hasn't applied for many releases.

61Enhancements:
62
63 - support for giflib 5.0. (5.0.1 and later)
64 https://rt.cpan.org/Ticket/Display.html?id=79029
65 The giflib API Imager uses doesn't have a mechanism to set the
66 header version in 5.0.0.
67
68 - update the GIF library probe code to check for the new giflib 5.0.1
69 EGifSetGifVersion() function, and to check for the giflib 4.2.0
70 uninitialized gif89 bug.
71 https://rt.cpan.org/Ticket/Display.html?id=79679
72 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
73
74 - avoid static variables when capturing IPTC data from JPEG files
75
76 - match Imager::Font;:T1's error message translations to those from
77 later versions of T1Lib.
78
79 - for libtiff versions that support extended warning handlers (3.8.0
80 or later), use them to avoid some global variables.
81
82 - note Image::ExifTool for better metadata support.

97===========
98
ef84bb32 99Bug fixes:
38742a13 100
289d65f4
TC
101 - The size of rotated images is no longer rounded up so aggressively.
102 Added rounding to the linear interpolation done for rotate() and
103 matrix_transform() for 1 and 3 channel 8-bit images.
104 Adjusted the two tranlate matrices used to build the final rotation
105 matrix to use the distance between the outlier pixels rather than
106 the pixel dimensions (ie. dimension-1).
107 With all of this the output of rotate(degrees => 270) on an 8-bit
108 image exactly matches the output of rotate(right => 270).
109 https://rt.cpan.org/Ticket/Display.html?id=77063
110
ef84bb32
TC
111Other changes:
112
113 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
114 internals, those names only matter for the XS interface.
115
116 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
117 the API level compiled into a loadable module such as
118 Imager::File::GIF doesn't match that of Imager. Previously it
119 could be difficult to determine exactly which module was failing to
120 load.
121 https://rt.cpan.org/Ticket/Display.html?id=77173
122
123 - added Imager->check_file_limits() as an interface to the
124 i_int_check_image_file_limits() API.
125
126 - Imager->set_file_limits(reset => 1) now resets the limits to the
127 defaults rather than setting them all to unlimited.
128
129 - wrote a brief security note as Imager::Security
130 https://rt.cpan.org/Ticket/Display.html?id=68910
131
6f31dd14 132Imager 0.90 - 30 Apr 2012
7c4464f5
TC
133===========
134
135Bug fixes:
136
137 - Imager::Test::is_imaged() attempted to process an "epsilon"
138 parameter but the prototype didn't allow for the extra parameter.
139 Corrected the prototype.
140
29b38678
TC
141 - when downconverting samples (eg. from floating point to 8 bit)
142 Imager now rounds the sample value rather than attempting to
143 allocate input values over output values equally. The old
144 behaviour had the probably surprising effect of converting a
145 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
146 2.
147 This may result in slightly different 8 or 16-bit output images.
148
e2a86bac
TC
149 - BI_BITFIELD BMP images were handled incorrectly, both in
150 incorrectly calculating the space required for the masks and in
151 processing the image data itself.
152 https://rt.cpan.org/Ticket/Display.html?id=76736
153
154 - some odd width BMP BI_RLE4 images use run lengths that run one off
155 the edge of the image. Imager now allows this, discarding the
156 extra column.
157
158 - odd length RLE4 runs in BMP images were decoded incorrectly.
159
82eb0687
TC
160 - pkg-config could sometimes return a library that was in a directory
161 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
162 If no -L is included in the pkg-config library information check if
163 EU::MM can find the library, and if not, search our configured
164 directories and insert that into the library flags.
165 https://rt.cpan.org/Ticket/Display.html?id=75869
166
de50f459
TC
167 - Imager::Probe can now probe for libraries with dependent libraries,
168 common for static linking, eg. libpng requires libz.
169 https://rt.cpan.org/Ticket/Display.html?id=74043
170
171 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
172
173 - added alternative probe configurations that try to link libz, to
174 handle a statically linked libpng.
175 https://rt.cpan.org/Ticket/Display.html?id=74043
176
177 - if a probe includes testcode, Imager::Probe now checks that code as
178 part of the process of checking each configuration rather than as a
179 post test of the found configuration. This allows alternate
180 configurations to be checked if a matching but non-working
181 configuration is found.
182 https://rt.cpan.org/Ticket/Display.html?id=74043
183
9d5ff8a6
TC
184Other changes:
185
186 - when reading or writing images via callbacks, the default callbacks
187 now push an error message indicating that a required callback was
188 called but not supplied.
189 https://rt.cpan.org/Ticket/Display.html?id=76782
190
191 - clarify which callbacks are required for reading and writing TIFF
192 images.
193
194 - improve logging for creation of callback I/O layers.
195
de50f459
TC
196 - a little more documentation for Imager::Probe.
197
594f5933
TC
198 - the i_get_file_background() and i_get_file_backgroundf() APIs now
199 return int to indicate whether the i_background tag was found.
200
1b46057d
TC
201 - PNG rework
202 - improve error reporting
203 - add png_interlace, png_bits tags
204 - read paletted images as paletted images, including transparency
205 - read 1 bit greyscale images as a type suitable for other file
206 handlers to write as bilevel
207 - read 16 bit/sample PNG as 16-bit/sample Imager images
208 - write "bilevel" paletted images as 1 bit grayscale images
209 - write paletted images as paletted images
210 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
211 images
212 - improved metadata support

215Imager 0.89 - 18 Mar 2012
216===========
217
218Bug fixes:
219
93eab01e
TC
220 - getpixel(..., type => "float") and the API i_gpixf() have been
221 broken on paletted images since they were implemented.

TC
224Other changes:
225
61be9694
TC
226 - links in the METHOD INDEX now point at the method documentation
227 rather than the heading you can find them under.
228 https://rt.cpan.org/Ticket/Display.html?id=71495
229
a5919365
TC
230 - Imager (and the bundled dynamic modules) no longer fallback to
231 using DynaLoader if loading via XSLoader fails.
232 For the bundled modules this could hide useful error messages.
233 https://rt.cpan.org/Ticket/Display.html?id=75560
234
335078fc
TC
235 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
236 buffer in the array of allocations, but just stores the filename
237 pointer and line number.

240Imager 0.88 - 22 Feb 2012
241===========
242
43bef43b
TC
243 - describe how to build libgif etc on OS X in such a way as to be
244 compatible with a fat binary perl (such as the system perl), in
245 README.
246 https://rt.cpan.org/Ticket/Display.html?id=73371
247
69675eef

TC
254 - note that the generator of the apparently non-DFSG-free postscript
255 in MMOne.pfb is a Debian package.
256
02323e69
TC
257 - setsamples() is now a true complement to getsamples() - it can
258 write 8-bit or floating point samples from a scalar or array
259 reference. This adds i_psamp() and i_psampf() to the C level API.
260
261 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
262 changed to make better use of the typemap, but these aren't part of
263 the perl level API anyway. There were no changes to the C level
264 interfaces to these functions.
265
2a27eeff
TC
266 - getpixel() and setpixel() now accept a mix of scalar and array
267 references for the x and y parameters, and unequal array lengths is
268 no longer an error.

279
5091168a
TC
280 - Win32 text output is now done in normal combine mode, the alpha
281 component of the color is now significant.

284 - remove long unused gif case from read()
285 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
286
7640e3bb
TC
287 - the getsamples() target parameter was being treated as a hashref
288 when it's meant to be an array reference.
289 https://rt.cpan.org/Ticket/Display.html?id=74882
290
2a27eeff
TC
291 - getpixel() and setpixel() now returns an empty list when invalid
292 parameters are supplied.
293 Invalid values for type now result in an error for getpixel().

TC
312 - make the error message from read() or read_multi() when they can't
313 identify the file type match reality.
314 https://rt.cpan.org/Ticket/Display.html?id=72475
315
316 - read() now uses $FORMATGUESS if it can't determine the file type
317 based on the file header, to match read_multi().
318
319 - re-work and add tests for def_guess_type(). def_guess_type() no
320 longer returns any random file extension as the file type.

332 - fix i_render_color() to properly draw in "normal" mode - ie. when
333 writing to a 1 or 3 channel image the second or fourth channel of

TC
416
417 - add simple tests for the Imager::Test test_image generators
418
6d5c85a2
TC
419 - io_glue I/O buffering re-work:
420
421 - reorganize io_glue to do it's own buffering by default
422
423 - the unbuffered functions are available as i_io_raw_read() (or
424 raw_read() from perl) etc but are not recommended for typical
425 use.
426
427 - use the new i_io_peekn() when checking for file magic to avoid
428 seek, allowing Imager to detect the file type and read the file
429 from an unseekable stream (for formats that don't use random
430 access)
431
432 - added several new I/O layer API functions.
433
434 - fix the TGA performance problem, most noticably on Win32
435 https://rt.cpan.org/Ticket/Display.html?id=70037
436
437 - TIFF now uses wrapper functions of the correct types to avoid casts
438 https://rt.cpan.org/Ticket/Display.html?id=69912
439
440 - the callback IO object did its own buffering, controlled by the
441 maxbuffer parameter supplied to the read() and write() methods.
442 This buffering has been removed, to avoid redundancy with the
443 common io_glue buffering. This also avoids a bug in that code
444 which could rarely pass a zero length to the read callback and
445 then panic about the result.
446
447 - the callback IO object now tests the result of calling the close
448 callback, which should return true for success.
449
450 - the PNM reader did its own buffering. This buffering has been
451 removed to avoid redundancy with the common io_glue buffering.
452
453 - previously the read handlers for fd and callback I/O layers would
454 call the underlying interface (POSIX read or your supplied callback)
455 until it filled the buffer. It now only makes one call.
456
457 - added public constructors for I/O layer objects (see Imager::IO)
458
459 - all core file handlers now use the i_io_foo() wrappers to gain
460 access to buffered I/O rather than calling the I/O layer
461 callbacks directly.
462
463 - all core file handlers now check for error on close.
464
465 - Backward compatibility: if you hava custom file handlers, you can
466 use i_io_write() etc since they're available as macros in older
467 versions of Imager.
468
469 - eliminate the final remnants of io_glue_commit_types().
470
471 - bump IMAGER_API_VERSION, since the above may break assumptions.
472
473 - removed the long unused i_gen_reader() and i_gen_writer() utility
474 functions.

TC
477===========
478
0c647c9a
TC
479The main changes in the release versus 0.84 are:
480
481 - on 64-bit systems, 64-bit types are consistently used for image
482 dimensions and co-ordinated, and for memory block sizes.
483
484 - handle IFD loops in TIFF files correctly. Previously this would
485 lead to an infinite loop.

534Imager 0.84_01 - 8 Aug 2011
535==============
536
537Development release as a sanity check for the types re-work.
8d14daab
TC
538
539Massive types re-work:
540
541 - the type used internally for pixel co-ordinates and image sizes is
542 now 64-bit on 64-bit platforms (at least sane ones).
543
544 - size_t is now used consistently for memory block sizes.
545
546 - since this changes the binary interface, the Imager API version has
547 been incremented. Any module that uses the API will need to be
548 rebuilt. In most cases that will be enough, but calls to any APIs
549 that take a pointer to image sizes may need source changes.
550
551 - you should be able to create very large images on 64-bit systems,
552 if you have enough memory. Successfully created a 32768 x 49192 x
553 3 channel image, filled with a tiled image and scaled it. The
554 unscaled image was also successfully saved to a JPEG.
555
556 - check the image size before attempting to write BMP, GIF, JPEG,
557 PNG, SGI, TGA, TIFF images.
558
559 - correctly handle reading TGA images over 32767 pixels wide or tall.
560
561Incidental changes:
562
563 - the gif_left and gif_top tags are now clamped to non-negative
564 values when writing a GIF image.
565
566 - removed dead callback read/write code
567
568The default maximum memory size when reading files is now 1G.

1278 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so

1598Imager 0.55 - 16 Dec 2006
1599===========
1600
1601This is primarily a bug fix release.
1602
1603Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1604
1605There is one new feature:
1606
1607 - the Win32 font driver now supports UTF8 (RT 22166)
1608 http://www.cpanforum.com/threads/3276
1609 http://rt.cpan.org/Ticket/Display.html?id=22166
1610
1611Several bugs were fixed:
1612
1613 - the string() method would not output the string "0"
1614 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1615
1616 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1617 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1618
1619 - the gif_disposal and gif_user_input tags weren't being read from
1620 the file correctly
1621 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1622
1623 - gif.c was failing to build under MSVC
1624 http://rt.cpan.org/Ticket/Display.html?id=23922
1625
1626 - in some cases strings passed to the string() method were treated as
1627 terminated by NUL (chr 0)
1628 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1629
1630 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1631 that's the default build name for zlib on Win32.
1632 http://rt.cpan.org/Ticket/Display.html?id=23064
1633
1634 - search $Config{incpath} for headers too, which we should have been
1635 doing all along.
1636
1637Win32 font driver fixes:
1638
1639 - the global descent value from bounding box was the wrong sign
1640 http://www.cpanforum.com/threads/3276
1641
1642 - if the first or last glyph overflowed the left or right side of the
1643 advance width they would be clipped
1644
1645
1646Imager 0.54 - 14 Sep 2006
1647===========
1648
1649This is primarily a feature release:
1650
1651 - a new qtype value 'mixing' has been added to the scale()
1652 method. This is faster than 'normal', slower than 'preview'. This
1653 is based on the method used by pnmscale, and seems to produce less
1654 blurry results than normal.
1655 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1656
1657 - the rubthrough() method can now render onto images with an alpha
1658 channel.
1659 http://rt.cpan.org/Ticket/Display.html?id=20678
1660
1661 - the read_multi() method now falls back to calling doing a single
1662 image read via the read() method and write_multi() will now fall
1663 back to calling write() if a single image is supplied. This means
1664 you can simply call the read_multi() or write_multi() functions
1665 without having to check if the type is formatted by that method.
1666 http://rt.cpan.org/Ticket/Display.html?id=19457
1667 http://rt.cpan.org/Ticket/Display.html?id=19458
1668
1669 - the GIF loop extension can now be written. If you don't have
1670 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1671 should upgrade.
1672 http://rt.cpan.org/Ticket/Display.html?id=21185
1673
1674 - getscanline() and setscanline() can now read/write palette index
1675 based data from/to the image for paletted images, by setting type to
1676 'index'.
1677 http://rt.cpan.org/Ticket/Display.html?id=20338
1678
1679 - we no longer hassle you to disable GIF support
1680 http://rt.cpan.org/Ticket/Display.html?id=20687
1681
1682 - minor documentation fixes
1683
1684
1685Imager 0.53 - 26 Jul 2006
1686===========
1687
1688This is a bugfix release.
1689
1690Some test code was left in a code path not covered by the test
1691suite. A test was added to cover this code path and the test code was
1692removed.

1695
1696Imager 0.52 - 25 Jul 2006
1697===========
1698
1699This is primarily a feature release, but contains a fair few bug
1700fixes, new features:
1701
1702 - ability to read and write MS Windows ICO and CUR files
1703
1704 - you can now add file format plugins to support new file formats
1705
1706 - add POD coverage tests
1707
1708 - setcolors() and addcolors() now accept color names and so on
1709 instead of requiring Imager::Color objects.
1710 http://rt.cpan.org/Ticket/Display.html?id=20056
1711
1712 - flood_fill() can now fill to a specified border color instead of
1713 just to the area the same color as the seed.
1714 http://rt.cpan.org/Ticket/Display.html?id=19618
1715
1716
1717Bug fixes:
1718
1719 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1720 calculating the advance width.
1721 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1722
1723 - bounding_box for the T1 driver wasn't including leading and
1724 trailing spaces in the bounding box as the other drivers did, it also
1725 produced strange results for empty strings or strings containing only
1726 spaces
1727
1728 - when reading CMYK jpeg images they were being transferred to the
1729 image object as is, producing a four channel image. It only looked ok
1730 due to an old still unfixed Photoshop bug. We now convert from the
1731 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1732 http://rt.cpan.org/Ticket/Display.html?id=20416
1733
1734 - reading a CYMK TIFF would result in a 4 channel image, reading any
1735 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1736 result in an error.
1737 http://rt.cpan.org/Ticket/Display.html?id=20415
1738
1739 - added /usr/local/include to the default include search path, since
1740 we were already searching /usr/local/lib for libraries.
1741
1742And various minor fixes and documentation updates.
1743
1744
1745Imager 0.51 - 23 Apr 2006
