17Bug fixes:
71fbe41a
TC
18
19 - previously a transparency enabled GIF write (the default) would
20 always use a GIF89a header even if none of the images were
21 transparent.

42Enhancements:
43
44 - support for giflib 5.0. (5.0.1 and later)
45 https://rt.cpan.org/Ticket/Display.html?id=79029
46 The giflib API Imager uses doesn't have a mechanism to set the
47 header version in 5.0.0.
48
49 - update the GIF library probe code to check for the new giflib 5.0.1
50 EGifSetGifVersion() function, and to check for the giflib 4.2.0
51 uninitialized gif89 bug.
52 https://rt.cpan.org/Ticket/Display.html?id=79679
53 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
54
55 - avoid static variables when capturing IPTC data from JPEG files
56
57 - match Imager::Font;:T1's error message translations to those from
58 later versions of T1Lib.
59
60 - for libtiff versions that support extended warning handlers (3.8.0
61 or later), use them to avoid some global variables.
62
63 - note Image::ExifTool for better metadata support.

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

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

197===========
198
199Bug fixes:
200
93eab01e
TC
201 - getpixel(..., type => "float") and the API i_gpixf() have been
202 broken on paletted images since they were implemented.

TC
205Other changes:

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

221Imager 0.88 - 22 Feb 2012
222===========
223
43bef43b
TC
224 - describe how to build libgif etc on OS X in such a way as to be
225 compatible with a fat binary perl (such as the system perl), in
226 README.
227 https://rt.cpan.org/Ticket/Display.html?id=73371
228
69675eef
TC
229 - update the change notes for 0.77_01 to indicate that libungif
230 support was removed.

234
3b7f10da
TC
235 - note that the generator of the apparently non-DFSG-free postscript
236 in MMOne.pfb is a Debian package.
237
02323e69
TC
238 - setsamples() is now a true complement to getsamples() - it can
239 write 8-bit or floating point samples from a scalar or array
240 reference. This adds i_psamp() and i_psampf() to the C level API.
241
242 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
243 changed to make better use of the typemap, but these aren't part of
244 the perl level API anyway. There were no changes to the C level
245 interfaces to these functions.
246
2a27eeff
TC
247 - getpixel() and setpixel() now accept a mix of scalar and array
248 references for the x and y parameters, and unequal array lengths is
249 no longer an error.
250 https://rt.cpan.org/Ticket/Display.html?id=73697

258 rotate().
259 https://rt.cpan.org/Ticket/Display.html?id=69261
260
5091168a
TC
261 - Win32 text output is now done in normal combine mode, the alpha
262 component of the color is now significant.

265 - remove long unused gif case from read()
266 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
267
7640e3bb
TC
268 - the getsamples() target parameter was being treated as a hashref
269 when it's meant to be an array reference.
270 https://rt.cpan.org/Ticket/Display.html?id=74882
271
2a27eeff
TC
272 - getpixel() and setpixel() now returns an empty list when invalid
273 parameters are supplied.
274 Invalid values for type now result in an error for getpixel().

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

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

360
361 - Imager::Font->new now produces better error messages for the T1
362 engine.
363
6e938c74
TC
364 - the font has_chars() method now returns perl's true and false
365 values in list context rather than integers, which should be more

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

515Imager 0.84_01 - 8 Aug 2011
516==============
517
518Development release as a sanity check for the types re-work.
8d14daab
TC
519
520Massive types re-work:
521
522 - the type used internally for pixel co-ordinates and image sizes is
523 now 64-bit on 64-bit platforms (at least sane ones).
524
525 - size_t is now used consistently for memory block sizes.
526
527 - since this changes the binary interface, the Imager API version has
528 been incremented. Any module that uses the API will need to be
529 rebuilt. In most cases that will be enough, but calls to any APIs
530 that take a pointer to image sizes may need source changes.
531
532 - you should be able to create very large images on 64-bit systems,
533 if you have enough memory. Successfully created a 32768 x 49192 x
534 3 channel image, filled with a tiled image and scaled it. The
535 unscaled image was also successfully saved to a JPEG.
536
537 - check the image size before attempting to write BMP, GIF, JPEG,
538 PNG, SGI, TGA, TIFF images.
539
540 - correctly handle reading TGA images over 32767 pixels wide or tall.
541
542Incidental changes:
543
544 - the gif_left and gif_top tags are now clamped to non-negative
545 values when writing a GIF image.
546
547 - removed dead callback read/write code
548
549The default maximum memory size when reading files is now 1G.

1196 - moved the imtoc.perl code into Imager::Preprocess

1201 noalpha channels or back.
1202 https://rt.cpan.org/Ticket/Display.html?id=30908
1203
1204 - rubthrough() now falls back to pasting when the source doesn't have
1205 an alpha channel. This effectively treats the source as having a
1206 max alpha channel, the right thing to do.
1207 http://rt.cpan.org/Ticket/Display.html?id=29944

1212 Rewrote most of the combine modes to match the way the SVG draft
1213 defines them with respect to a translucent source and destination.

1258 problem with loading such an image. I haven't been able to find any
1259 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1260 I'll match it's behaviour. See issue 114913 in the GIMP's

1579Imager 0.55 - 16 Dec 2006
1580===========
1581
1582This is primarily a bug fix release.
1583
1584Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1585
1586There is one new feature:
1587
1588 - the Win32 font driver now supports UTF8 (RT 22166)
1589 http://www.cpanforum.com/threads/3276
1590 http://rt.cpan.org/Ticket/Display.html?id=22166
1591
1592Several bugs were fixed:
1593
1594 - the string() method would not output the string "0"
1595 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1596
1597 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1598 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1599
1600 - the gif_disposal and gif_user_input tags weren't being read from
1601 the file correctly
1602 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1603
1604 - gif.c was failing to build under MSVC
1605 http://rt.cpan.org/Ticket/Display.html?id=23922
1606
1607 - in some cases strings passed to the string() method were treated as
1608 terminated by NUL (chr 0)
1609 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1610
1611 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1612 that's the default build name for zlib on Win32.
1613 http://rt.cpan.org/Ticket/Display.html?id=23064
1614
1615 - search $Config{incpath} for headers too, which we should have been
1616 doing all along.
1617
1618Win32 font driver fixes:
1619
1620 - the global descent value from bounding box was the wrong sign
1621 http://www.cpanforum.com/threads/3276
1622
1623 - if the first or last glyph overflowed the left or right side of the
1624 advance width they would be clipped
1625
1626
1627Imager 0.54 - 14 Sep 2006
1628===========
1629
1630This is primarily a feature release:
1631
1632 - a new qtype value 'mixing' has been added to the scale()
1633 method. This is faster than 'normal', slower than 'preview'. This
1634 is based on the method used by pnmscale, and seems to produce less
1635 blurry results than normal.
1636 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1637
1638 - the rubthrough() method can now render onto images with an alpha
1639 channel.
1640 http://rt.cpan.org/Ticket/Display.html?id=20678
1641
1642 - the read_multi() method now falls back to calling doing a single
1643 image read via the read() method and write_multi() will now fall
1644 back to calling write() if a single image is supplied. This means
1645 you can simply call the read_multi() or write_multi() functions
1646 without having to check if the type is formatted by that method.
1647 http://rt.cpan.org/Ticket/Display.html?id=19457
1648 http://rt.cpan.org/Ticket/Display.html?id=19458
1649
1650 - the GIF loop extension can now be written. If you don't have
1651 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1652 should upgrade.
1653 http://rt.cpan.org/Ticket/Display.html?id=21185
1654
1655 - getscanline() and setscanline() can now read/write palette index
1656 based data from/to the image for paletted images, by setting type to
1657 'index'.
1658 http://rt.cpan.org/Ticket/Display.html?id=20338
1659
1660 - we no longer hassle you to disable GIF support
1661 http://rt.cpan.org/Ticket/Display.html?id=20687
1662
1663 - minor documentation fixes
1664
1665
1666Imager 0.53 - 26 Jul 2006
1667===========
1668
1669This is a bugfix release.
1670
1671Some test code was left in a code path not covered by the test
1672suite. A test was added to cover this code path and the test code was
1673removed.

1677Imager 0.52 - 25 Jul 2006
1678===========
1679
1680This is primarily a feature release, but contains a fair few bug
1681fixes, new features:
1682
1683 - ability to read and write MS Windows ICO and CUR files
1684
1685 - you can now add file format plugins to support new file formats
1686
1687 - add POD coverage tests
1688
1689 - setcolors() and addcolors() now accept color names and so on
1690 instead of requiring Imager::Color objects.
1691 http://rt.cpan.org/Ticket/Display.html?id=20056
1692
1693 - flood_fill() can now fill to a specified border color instead of
1694 just to the area the same color as the seed.
1695 http://rt.cpan.org/Ticket/Display.html?id=19618
1696
1697
1698Bug fixes:
1699
1700 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1701 calculating the advance width.
1702 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1703
1704 - bounding_box for the T1 driver wasn't including leading and
1705 trailing spaces in the bounding box as the other drivers did, it also
1706 produced strange results for empty strings or strings containing only
1707 spaces
1708
1709 - when reading CMYK jpeg images they were being transferred to the
1710 image object as is, producing a four channel image. It only looked ok
1711 due to an old still unfixed Photoshop bug. We now convert from the
1712 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1713 http://rt.cpan.org/Ticket/Display.html?id=20416
1714
1715 - reading a CYMK TIFF would result in a 4 channel image, reading any
1716 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1717 result in an error.
1718 http://rt.cpan.org/Ticket/Display.html?id=20415
1719
1720 - added /usr/local/include to the default include search path, since
1721 we were already searching /usr/local/lib for libraries.
1722
1723And various minor fixes and documentation updates.
1724
1725
1726Imager 0.51 - 23 Apr 2006
