10 - match Imager::Font;:T1's error message translations to those from
11 later versions of T1Lib.
12
13 - for libtiff versions that support extended warning handlers (3.8.0
14 or later), use them to avoid some global variables.
15
16 - catch an invalid matrix parameter to convert() instead of crashing
17 https://rt.cpan.org/Ticket/Display.html?id=79922
18

ef84bb32 43Bug fixes:
38742a13 44
289d65f4
TC
45 - The size of rotated images is no longer rounded up so aggressively.
46 Added rounding to the linear interpolation done for rotate() and
47 matrix_transform() for 1 and 3 channel 8-bit images.
48 Adjusted the two tranlate matrices used to build the final rotation
49 matrix to use the distance between the outlier pixels rather than
50 the pixel dimensions (ie. dimension-1).
51 With all of this the output of rotate(degrees => 270) on an 8-bit
52 image exactly matches the output of rotate(right => 270).
53 https://rt.cpan.org/Ticket/Display.html?id=77063
54
ef84bb32
TC
55Other changes:
56
57 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
58 internals, those names only matter for the XS interface.
59
60 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
61 the API level compiled into a loadable module such as
62 Imager::File::GIF doesn't match that of Imager. Previously it
63 could be difficult to determine exactly which module was failing to
64 load.
65 https://rt.cpan.org/Ticket/Display.html?id=77173
66
67 - added Imager->check_file_limits() as an interface to the
68 i_int_check_image_file_limits() API.
69
70 - Imager->set_file_limits(reset => 1) now resets the limits to the
71 defaults rather than setting them all to unlimited.
72
73 - wrote a brief security note as Imager::Security
74 https://rt.cpan.org/Ticket/Display.html?id=68910
75
6f31dd14 76Imager 0.90 - 30 Apr 2012
7c4464f5
TC
77===========
78
79Bug fixes:
80
81 - Imager::Test::is_imaged() attempted to process an "epsilon"
82 parameter but the prototype didn't allow for the extra parameter.
83 Corrected the prototype.
84
29b38678
TC
85 - when downconverting samples (eg. from floating point to 8 bit)
86 Imager now rounds the sample value rather than attempting to
87 allocate input values over output values equally. The old
88 behaviour had the probably surprising effect of converting a
89 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
90 2.
91 This may result in slightly different 8 or 16-bit output images.
92
e2a86bac
TC
93 - BI_BITFIELD BMP images were handled incorrectly, both in
94 incorrectly calculating the space required for the masks and in
95 processing the image data itself.
96 https://rt.cpan.org/Ticket/Display.html?id=76736
97
98 - some odd width BMP BI_RLE4 images use run lengths that run one off
99 the edge of the image. Imager now allows this, discarding the
100 extra column.
101
102 - odd length RLE4 runs in BMP images were decoded incorrectly.
103
82eb0687
TC
104 - pkg-config could sometimes return a library that was in a directory
105 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
106 If no -L is included in the pkg-config library information check if
107 EU::MM can find the library, and if not, search our configured
108 directories and insert that into the library flags.
109 https://rt.cpan.org/Ticket/Display.html?id=75869
110
de50f459
TC
111 - Imager::Probe can now probe for libraries with dependent libraries,
112 common for static linking, eg. libpng requires libz.
113 https://rt.cpan.org/Ticket/Display.html?id=74043
114
115 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
116
117 - added alternative probe configurations that try to link libz, to
118 handle a statically linked libpng.
119 https://rt.cpan.org/Ticket/Display.html?id=74043
120
121 - if a probe includes testcode, Imager::Probe now checks that code as
122 part of the process of checking each configuration rather than as a
123 post test of the found configuration. This allows alternate
124 configurations to be checked if a matching but non-working
125 configuration is found.
126 https://rt.cpan.org/Ticket/Display.html?id=74043
127
9d5ff8a6
TC
128Other changes:
129
130 - when reading or writing images via callbacks, the default callbacks
131 now push an error message indicating that a required callback was
132 called but not supplied.
133 https://rt.cpan.org/Ticket/Display.html?id=76782
134
135 - clarify which callbacks are required for reading and writing TIFF
136 images.
137
138 - improve logging for creation of callback I/O layers.
139
de50f459
TC
140 - a little more documentation for Imager::Probe.
141
594f5933
TC
142 - the i_get_file_background() and i_get_file_backgroundf() APIs now
143 return int to indicate whether the i_background tag was found.
144
1b46057d
TC
145 - PNG rework
146 - improve error reporting
147 - add png_interlace, png_bits tags
148 - read paletted images as paletted images, including transparency
149 - read 1 bit greyscale images as a type suitable for other file
150 handlers to write as bilevel
151 - read 16 bit/sample PNG as 16-bit/sample Imager images
152 - write "bilevel" paletted images as 1 bit grayscale images
153 - write paletted images as paletted images
154 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
155 images
156 - improved metadata support

160===========
161
162Bug fixes:
163
93eab01e
TC
164 - getpixel(..., type => "float") and the API i_gpixf() have been
165 broken on paletted images since they were implemented.

TC
168Other changes:

170 - links in the METHOD INDEX now point at the method documentation
171 rather than the heading you can find them under.
172 https://rt.cpan.org/Ticket/Display.html?id=71495
173
a5919365
TC
174 - Imager (and the bundled dynamic modules) no longer fallback to
175 using DynaLoader if loading via XSLoader fails.
176 For the bundled modules this could hide useful error messages.
177 https://rt.cpan.org/Ticket/Display.html?id=75560
178
335078fc
TC
179 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
180 buffer in the array of allocations, but just stores the filename
181 pointer and line number.

184Imager 0.88 - 22 Feb 2012
185===========
186
43bef43b
TC
187 - describe how to build libgif etc on OS X in such a way as to be
188 compatible with a fat binary perl (such as the system perl), in
189 README.
190 https://rt.cpan.org/Ticket/Display.html?id=73371
191

TC
198 - note that the generator of the apparently non-DFSG-free postscript
199 in MMOne.pfb is a Debian package.
200
02323e69
TC
201 - setsamples() is now a true complement to getsamples() - it can
202 write 8-bit or floating point samples from a scalar or array
203 reference. This adds i_psamp() and i_psampf() to the C level API.
204
205 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
206 changed to make better use of the typemap, but these aren't part of
207 the perl level API anyway. There were no changes to the C level
208 interfaces to these functions.
209
2a27eeff
TC
210 - getpixel() and setpixel() now accept a mix of scalar and array
211 references for the x and y parameters, and unequal array lengths is
212 no longer an error.

223
5091168a
TC
224 - Win32 text output is now done in normal combine mode, the alpha
225 component of the color is now significant.

228 - remove long unused gif case from read()
229 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
230
7640e3bb
TC
231 - the getsamples() target parameter was being treated as a hashref
232 when it's meant to be an array reference.
233 https://rt.cpan.org/Ticket/Display.html?id=74882
234
2a27eeff
TC
235 - getpixel() and setpixel() now returns an empty list when invalid
236 parameters are supplied.
237 Invalid values for type now result in an error for getpixel().

TC
256 - make the error message from read() or read_multi() when they can't
257 identify the file type match reality.
258 https://rt.cpan.org/Ticket/Display.html?id=72475
259
260 - read() now uses $FORMATGUESS if it can't determine the file type
261 based on the file header, to match read_multi().
262
263 - re-work and add tests for def_guess_type(). def_guess_type() no
264 longer returns any random file extension as the file type.

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

313 it.
314
5efba0c6

322 creation.
323
324 - Imager::Font->new now produces better error messages for the T1
325 engine.
326
6e938c74
TC
327 - the font has_chars() method now returns perl's true and false
328 values in list context rather than integers, which should be more
329 efficient.

345
336ce474
TC
346 - we rely on Config.pm's d_vsnprintf as to whether we use
347 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
348 though it only has _ prefixed versions of these. Define our own
349 prefixed names on Win32.

TC
360
361 - add simple tests for the Imager::Test test_image generators
362
6d5c85a2
TC
363 - io_glue I/O buffering re-work:
364
365 - reorganize io_glue to do it's own buffering by default
366
367 - the unbuffered functions are available as i_io_raw_read() (or
368 raw_read() from perl) etc but are not recommended for typical
369 use.
370
371 - use the new i_io_peekn() when checking for file magic to avoid
372 seek, allowing Imager to detect the file type and read the file
373 from an unseekable stream (for formats that don't use random
374 access)
375
376 - added several new I/O layer API functions.
377
378 - fix the TGA performance problem, most noticably on Win32
379 https://rt.cpan.org/Ticket/Display.html?id=70037
380
381 - TIFF now uses wrapper functions of the correct types to avoid casts
382 https://rt.cpan.org/Ticket/Display.html?id=69912
383
384 - the callback IO object did its own buffering, controlled by the
385 maxbuffer parameter supplied to the read() and write() methods.
386 This buffering has been removed, to avoid redundancy with the
387 common io_glue buffering. This also avoids a bug in that code
388 which could rarely pass a zero length to the read callback and
389 then panic about the result.
390
391 - the callback IO object now tests the result of calling the close
392 callback, which should return true for success.
393
394 - the PNM reader did its own buffering. This buffering has been
395 removed to avoid redundancy with the common io_glue buffering.
396
397 - previously the read handlers for fd and callback I/O layers would
398 call the underlying interface (POSIX read or your supplied callback)
399 until it filled the buffer. It now only makes one call.
400
401 - added public constructors for I/O layer objects (see Imager::IO)
402
403 - all core file handlers now use the i_io_foo() wrappers to gain
404 access to buffered I/O rather than calling the I/O layer
405 callbacks directly.
406
407 - all core file handlers now check for error on close.
408
409 - Backward compatibility: if you hava custom file handlers, you can
410 use i_io_write() etc since they're available as macros in older
411 versions of Imager.
412
413 - eliminate the final remnants of io_glue_commit_types().
414
415 - bump IMAGER_API_VERSION, since the above may break assumptions.
416
417 - removed the long unused i_gen_reader() and i_gen_writer() utility
418 functions.

0c647c9a
TC
423The main changes in the release versus 0.84 are:
424
425 - on 64-bit systems, 64-bit types are consistently used for image
426 dimensions and co-ordinated, and for memory block sizes.
427
428 - handle IFD loops in TIFF files correctly. Previously this would
429 lead to an infinite loop.

478Imager 0.84_01 - 8 Aug 2011
479==============
480
481Development release as a sanity check for the types re-work.
8d14daab
TC
482
483Massive types re-work:
484
485 - the type used internally for pixel co-ordinates and image sizes is
486 now 64-bit on 64-bit platforms (at least sane ones).
487
488 - size_t is now used consistently for memory block sizes.
489
490 - since this changes the binary interface, the Imager API version has
491 been incremented. Any module that uses the API will need to be
492 rebuilt. In most cases that will be enough, but calls to any APIs
493 that take a pointer to image sizes may need source changes.
494
495 - you should be able to create very large images on 64-bit systems,
496 if you have enough memory. Successfully created a 32768 x 49192 x
497 3 channel image, filled with a tiled image and scaled it. The
498 unscaled image was also successfully saved to a JPEG.
499
500 - check the image size before attempting to write BMP, GIF, JPEG,
501 PNG, SGI, TGA, TIFF images.
502
503 - correctly handle reading TGA images over 32767 pixels wide or tall.
504
505Incidental changes:
506
507 - the gif_left and gif_top tags are now clamped to non-negative
508 values when writing a GIF image.
509
510 - removed dead callback read/write code
511
512The default maximum memory size when reading files is now 1G.

1159 - moved the imtoc.perl code into Imager::Preprocess

1164 noalpha channels or back.
1165 https://rt.cpan.org/Ticket/Display.html?id=30908
1166
1167 - rubthrough() now falls back to pasting when the source doesn't have
1168 an alpha channel. This effectively treats the source as having a
1169 max alpha channel, the right thing to do.
1170 http://rt.cpan.org/Ticket/Display.html?id=29944

1175 Rewrote most of the combine modes to match the way the SVG draft
1176 defines them with respect to a translucent source and destination.

1221 problem with loading such an image. I haven't been able to find any
1222 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1223 I'll match it's behaviour. See issue 114913 in the GIMP's

1381 - the mask for ICO/CUR images is now applied as an alpha channel to

1542Imager 0.55 - 16 Dec 2006
1543===========
1544
1545This is primarily a bug fix release.
1546
1547Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1548
1549There is one new feature:
1550
1551 - the Win32 font driver now supports UTF8 (RT 22166)
1552 http://www.cpanforum.com/threads/3276
1553 http://rt.cpan.org/Ticket/Display.html?id=22166
1554
1555Several bugs were fixed:
1556
1557 - the string() method would not output the string "0"
1558 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1559
1560 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1561 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1562
1563 - the gif_disposal and gif_user_input tags weren't being read from
1564 the file correctly
1565 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1566
1567 - gif.c was failing to build under MSVC
1568 http://rt.cpan.org/Ticket/Display.html?id=23922
1569
1570 - in some cases strings passed to the string() method were treated as
1571 terminated by NUL (chr 0)
1572 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1573
1574 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1575 that's the default build name for zlib on Win32.
1576 http://rt.cpan.org/Ticket/Display.html?id=23064
1577
1578 - search $Config{incpath} for headers too, which we should have been
1579 doing all along.
1580
1581Win32 font driver fixes:
1582
1583 - the global descent value from bounding box was the wrong sign
1584 http://www.cpanforum.com/threads/3276
1585
1586 - if the first or last glyph overflowed the left or right side of the
1587 advance width they would be clipped
1588
1589
1590Imager 0.54 - 14 Sep 2006
1591===========
1592
1593This is primarily a feature release:
1594
1595 - a new qtype value 'mixing' has been added to the scale()
1596 method. This is faster than 'normal', slower than 'preview'. This
1597 is based on the method used by pnmscale, and seems to produce less
1598 blurry results than normal.
1599 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1600
1601 - the rubthrough() method can now render onto images with an alpha
1602 channel.
1603 http://rt.cpan.org/Ticket/Display.html?id=20678
1604
1605 - the read_multi() method now falls back to calling doing a single
1606 image read via the read() method and write_multi() will now fall
1607 back to calling write() if a single image is supplied. This means
1608 you can simply call the read_multi() or write_multi() functions
1609 without having to check if the type is formatted by that method.
1610 http://rt.cpan.org/Ticket/Display.html?id=19457
1611 http://rt.cpan.org/Ticket/Display.html?id=19458
1612
1613 - the GIF loop extension can now be written. If you don't have
1614 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1615 should upgrade.
1616 http://rt.cpan.org/Ticket/Display.html?id=21185
1617
1618 - getscanline() and setscanline() can now read/write palette index
1619 based data from/to the image for paletted images, by setting type to
1620 'index'.
1621 http://rt.cpan.org/Ticket/Display.html?id=20338
1622
1623 - we no longer hassle you to disable GIF support
1624 http://rt.cpan.org/Ticket/Display.html?id=20687
1625
1626 - minor documentation fixes
1627
1628
1629Imager 0.53 - 26 Jul 2006
1630===========
1631
1632This is a bugfix release.
1633
1634Some test code was left in a code path not covered by the test
1635suite. A test was added to cover this code path and the test code was
1636removed.

1639
1640Imager 0.52 - 25 Jul 2006
1641===========
1642
1643This is primarily a feature release, but contains a fair few bug
1644fixes, new features:
1645
1646 - ability to read and write MS Windows ICO and CUR files
1647
1648 - you can now add file format plugins to support new file formats
1649
1650 - add POD coverage tests
1651
1652 - setcolors() and addcolors() now accept color names and so on
1653 instead of requiring Imager::Color objects.
1654 http://rt.cpan.org/Ticket/Display.html?id=20056
1655
1656 - flood_fill() can now fill to a specified border color instead of
1657 just to the area the same color as the seed.
1658 http://rt.cpan.org/Ticket/Display.html?id=19618
1659
1660
1661Bug fixes:
1662
1663 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1664 calculating the advance width.
1665 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1666
1667 - bounding_box for the T1 driver wasn't including leading and
1668 trailing spaces in the bounding box as the other drivers did, it also
1669 produced strange results for empty strings or strings containing only
1670 spaces
1671
1672 - when reading CMYK jpeg images they were being transferred to the
1673 image object as is, producing a four channel image. It only looked ok
1674 due to an old still unfixed Photoshop bug. We now convert from the
1675 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1676 http://rt.cpan.org/Ticket/Display.html?id=20416
1677
1678 - reading a CYMK TIFF would result in a 4 channel image, reading any
1679 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1680 result in an error.
1681 http://rt.cpan.org/Ticket/Display.html?id=20415
1682
1683 - added /usr/local/include to the default include search path, since
1684 we were already searching /usr/local/lib for libraries.
1685
1686And various minor fixes and documentation updates.
1687
1688
1689Imager 0.51 - 23 Apr 2006
