289d65f4
TC
5 - The size of rotated images is no longer rounded up so aggressively.
6 Added rounding to the linear interpolation done for rotate() and
7 matrix_transform() for 1 and 3 channel 8-bit images.
8 Adjusted the two tranlate matrices used to build the final rotation
9 matrix to use the distance between the outlier pixels rather than
10 the pixel dimensions (ie. dimension-1).
11 With all of this the output of rotate(degrees => 270) on an 8-bit
12 image exactly matches the output of rotate(right => 270).

15Other changes:
16
17 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
18 internals, those names only matter for the XS interface.
19
20 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
21 the API level compiled into a loadable module such as
22 Imager::File::GIF doesn't match that of Imager. Previously it
23 could be difficult to determine exactly which module was failing to
24 load.
25 https://rt.cpan.org/Ticket/Display.html?id=77173
26
27 - added Imager->check_file_limits() as an interface to the
28 i_int_check_image_file_limits() API.
29
30 - Imager->set_file_limits(reset => 1) now resets the limits to the
31 defaults rather than setting them all to unlimited.
32
33 - wrote a brief security note as Imager::Security

TC
37===========
38
39Bug fixes:
40
41 - Imager::Test::is_imaged() attempted to process an "epsilon"
42 parameter but the prototype didn't allow for the extra parameter.
43 Corrected the prototype.
44
29b38678
TC
45 - when downconverting samples (eg. from floating point to 8 bit)
46 Imager now rounds the sample value rather than attempting to
47 allocate input values over output values equally. The old
48 behaviour had the probably surprising effect of converting a
49 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
50 2.
51 This may result in slightly different 8 or 16-bit output images.
52
e2a86bac
TC
53 - BI_BITFIELD BMP images were handled incorrectly, both in
54 incorrectly calculating the space required for the masks and in
55 processing the image data itself.
56 https://rt.cpan.org/Ticket/Display.html?id=76736
57
58 - some odd width BMP BI_RLE4 images use run lengths that run one off
59 the edge of the image. Imager now allows this, discarding the
60 extra column.
61
62 - odd length RLE4 runs in BMP images were decoded incorrectly.
63
82eb0687
TC
64 - pkg-config could sometimes return a library that was in a directory
65 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
66 If no -L is included in the pkg-config library information check if
67 EU::MM can find the library, and if not, search our configured
68 directories and insert that into the library flags.
69 https://rt.cpan.org/Ticket/Display.html?id=75869
70
de50f459
TC
71 - Imager::Probe can now probe for libraries with dependent libraries,
72 common for static linking, eg. libpng requires libz.
73 https://rt.cpan.org/Ticket/Display.html?id=74043
74
75 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
76
77 - added alternative probe configurations that try to link libz, to
78 handle a statically linked libpng.
79 https://rt.cpan.org/Ticket/Display.html?id=74043
80
81 - if a probe includes testcode, Imager::Probe now checks that code as
82 part of the process of checking each configuration rather than as a
83 post test of the found configuration. This allows alternate
84 configurations to be checked if a matching but non-working
85 configuration is found.
86 https://rt.cpan.org/Ticket/Display.html?id=74043
87
9d5ff8a6
TC
88Other changes:
89
90 - when reading or writing images via callbacks, the default callbacks
91 now push an error message indicating that a required callback was
92 called but not supplied.
93 https://rt.cpan.org/Ticket/Display.html?id=76782
94
95 - clarify which callbacks are required for reading and writing TIFF
96 images.
97
98 - improve logging for creation of callback I/O layers.
99
de50f459
TC
100 - a little more documentation for Imager::Probe.
101
594f5933
TC
102 - the i_get_file_background() and i_get_file_backgroundf() APIs now
103 return int to indicate whether the i_background tag was found.
104
1b46057d
TC
105 - PNG rework
106 - improve error reporting
107 - add png_interlace, png_bits tags
108 - read paletted images as paletted images, including transparency
109 - read 1 bit greyscale images as a type suitable for other file
110 handlers to write as bilevel
111 - read 16 bit/sample PNG as 16-bit/sample Imager images
112 - write "bilevel" paletted images as 1 bit grayscale images
113 - write paletted images as paletted images
114 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
115 images
116 - improved metadata support

120===========
121
122Bug fixes:
123
93eab01e
TC
124 - getpixel(..., type => "float") and the API i_gpixf() have been
125 broken on paletted images since they were implemented.

TC
128Other changes:
129
61be9694
TC
130 - links in the METHOD INDEX now point at the method documentation
131 rather than the heading you can find them under.
132 https://rt.cpan.org/Ticket/Display.html?id=71495
133
a5919365
TC
134 - Imager (and the bundled dynamic modules) no longer fallback to
135 using DynaLoader if loading via XSLoader fails.
136 For the bundled modules this could hide useful error messages.
137 https://rt.cpan.org/Ticket/Display.html?id=75560
138
335078fc
TC
139 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
140 buffer in the array of allocations, but just stores the filename
141 pointer and line number.

144Imager 0.88 - 22 Feb 2012
145===========
146
43bef43b
TC
147 - describe how to build libgif etc on OS X in such a way as to be
148 compatible with a fat binary perl (such as the system perl), in
149 README.
150 https://rt.cpan.org/Ticket/Display.html?id=73371
151
69675eef
TC
152 - update the change notes for 0.77_01 to indicate that libungif
153 support was removed.
154

TC
155 - add some other imaging modules to SEE ALSO
156 https://rt.cpan.org/Ticket/Display.html?id=73906
157
3b7f10da
TC
158 - note that the generator of the apparently non-DFSG-free postscript
159 in MMOne.pfb is a Debian package.
160
02323e69
TC
161 - setsamples() is now a true complement to getsamples() - it can
162 write 8-bit or floating point samples from a scalar or array
163 reference. This adds i_psamp() and i_psampf() to the C level API.
164
165 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
166 changed to make better use of the typemap, but these aren't part of
167 the perl level API anyway. There were no changes to the C level
168 interfaces to these functions.
169
2a27eeff
TC
170 - getpixel() and setpixel() now accept a mix of scalar and array
171 references for the x and y parameters, and unequal array lengths is
172 no longer an error.
173 https://rt.cpan.org/Ticket/Display.html?id=73697

181 rotate().
182 https://rt.cpan.org/Ticket/Display.html?id=69261
183
5091168a
TC
184 - Win32 text output is now done in normal combine mode, the alpha
185 component of the color is now significant.
186 https://rt.cpan.org/Ticket/Display.html?id=70014
187
fa0b1452
TC
188 - remove long unused gif case from read()
189 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
190
7640e3bb
TC
191 - the getsamples() target parameter was being treated as a hashref
192 when it's meant to be an array reference.
193 https://rt.cpan.org/Ticket/Display.html?id=74882
194
2a27eeff
TC
195 - getpixel() and setpixel() now returns an empty list when invalid
196 parameters are supplied.
197 Invalid values for type now result in an error for getpixel().

TC
216 - make the error message from read() or read_multi() when they can't
217 identify the file type match reality.
218 https://rt.cpan.org/Ticket/Display.html?id=72475
219
220 - read() now uses $FORMATGUESS if it can't determine the file type
221 based on the file header, to match read_multi().
222
223 - re-work and add tests for def_guess_type(). def_guess_type() no
224 longer returns any random file extension as the file type.

a044f2c6
TC
236 - fix i_render_color() to properly draw in "normal" mode - ie. when
237 writing to a 1 or 3 channel image the second or fourth channel of
238 the source color was being ignored, it is now significant.

273 it.
274
5efba0c6
TC
275 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
276 to synthesize it from overloaded "".

TC
278 - use T1_StrError() for error messages on modern libt1
279 https://rt.cpan.org/Ticket/Display.html?id=69879
280
281 - actually load the font rather than just adding it to the catalog on
282 creation.
283
284 - Imager::Font->new now produces better error messages for the T1
285 engine.
286
6e938c74
TC
287 - the font has_chars() method now returns perl's true and false
288 values in list context rather than integers, which should be more
289 efficient.

302 - make the APIRef synopsis ordering consistent, older versions of
303 perl could order it differently.
304 https://rt.cpan.org/Ticket/Display.html?id=71675
305
336ce474
TC
306 - we rely on Config.pm's d_vsnprintf as to whether we use
307 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
308 though it only has _ prefixed versions of these. Define our own
309 prefixed names on Win32.

a7e32beb
TC
320
321 - add simple tests for the Imager::Test test_image generators
322
6d5c85a2
TC
323 - io_glue I/O buffering re-work:
324
325 - reorganize io_glue to do it's own buffering by default
326
327 - the unbuffered functions are available as i_io_raw_read() (or
328 raw_read() from perl) etc but are not recommended for typical
329 use.
330
331 - use the new i_io_peekn() when checking for file magic to avoid
332 seek, allowing Imager to detect the file type and read the file
333 from an unseekable stream (for formats that don't use random
334 access)
335
336 - added several new I/O layer API functions.
337
338 - fix the TGA performance problem, most noticably on Win32
339 https://rt.cpan.org/Ticket/Display.html?id=70037
340
341 - TIFF now uses wrapper functions of the correct types to avoid casts
342 https://rt.cpan.org/Ticket/Display.html?id=69912
343
344 - the callback IO object did its own buffering, controlled by the
345 maxbuffer parameter supplied to the read() and write() methods.
346 This buffering has been removed, to avoid redundancy with the
347 common io_glue buffering. This also avoids a bug in that code
348 which could rarely pass a zero length to the read callback and
349 then panic about the result.
350
351 - the callback IO object now tests the result of calling the close
352 callback, which should return true for success.
353
354 - the PNM reader did its own buffering. This buffering has been
355 removed to avoid redundancy with the common io_glue buffering.
356
357 - previously the read handlers for fd and callback I/O layers would
358 call the underlying interface (POSIX read or your supplied callback)
359 until it filled the buffer. It now only makes one call.
360
361 - added public constructors for I/O layer objects (see Imager::IO)
362
363 - all core file handlers now use the i_io_foo() wrappers to gain
364 access to buffered I/O rather than calling the I/O layer
365 callbacks directly.
366
367 - all core file handlers now check for error on close.
368
369 - Backward compatibility: if you hava custom file handlers, you can
370 use i_io_write() etc since they're available as macros in older
371 versions of Imager.
372
373 - eliminate the final remnants of io_glue_commit_types().
374
375 - bump IMAGER_API_VERSION, since the above may break assumptions.
376
377 - removed the long unused i_gen_reader() and i_gen_writer() utility
378 functions.

TC
381===========
382
0c647c9a
TC
383The main changes in the release versus 0.84 are:
384
385 - on 64-bit systems, 64-bit types are consistently used for image
386 dimensions and co-ordinated, and for memory block sizes.
387
388 - handle IFD loops in TIFF files correctly. Previously this would
389 lead to an infinite loop.

TC
411 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate

438Imager 0.84_01 - 8 Aug 2011
439==============
440
441Development release as a sanity check for the types re-work.
8d14daab
TC
442
443Massive types re-work:
444
445 - the type used internally for pixel co-ordinates and image sizes is
446 now 64-bit on 64-bit platforms (at least sane ones).
447
448 - size_t is now used consistently for memory block sizes.
449
450 - since this changes the binary interface, the Imager API version has
451 been incremented. Any module that uses the API will need to be
452 rebuilt. In most cases that will be enough, but calls to any APIs
453 that take a pointer to image sizes may need source changes.
454
455 - you should be able to create very large images on 64-bit systems,
456 if you have enough memory. Successfully created a 32768 x 49192 x
457 3 channel image, filled with a tiled image and scaled it. The
458 unscaled image was also successfully saved to a JPEG.
459
460 - check the image size before attempting to write BMP, GIF, JPEG,
461 PNG, SGI, TGA, TIFF images.
462
463 - correctly handle reading TGA images over 32767 pixels wide or tall.
464

919 - the conv filter now enforces that the sum of the coefficients is
920 non-zero. Also, rather than skipping pixels off the edge off the
921 edge of the image, the closest edge pixel is used. Previously
922 dividing by the zero sum of coefficients could cause invalid
923 results or runtime exceptions.

1110This release primarily contains changes to improve ease of use -
1111rather than you having to convert images to the appropriate number of

1119 - moved the imtoc.perl code into Imager::Preprocess

1121 - paste() and rubthrough() now adapt the source image data to the
1122 destination, so you can now safely paste/rubthrough from greyscale
1123 images to color images or back, or from alpha channel images to
1124 noalpha channels or back.
1125 https://rt.cpan.org/Ticket/Display.html?id=30908
1126
1127 - rubthrough() now falls back to pasting when the source doesn't have
1128 an alpha channel. This effectively treats the source as having a
1129 max alpha channel, the right thing to do.
1130 http://rt.cpan.org/Ticket/Display.html?id=29944
1131
1132 - re-worked most of the area filling code to use a common set of
1133 functions when filling.
1134 Corrected normal combine mode.
1135 Rewrote most of the combine modes to match the way the SVG draft
1136 defines them with respect to a translucent source and destination.
1137 Added tests for translucent source and destination.
1138 Added tests to check 8-bit/sample and double/sample combines work
1139 similarly.

1178 - handling of the left-over bit for 16-bit/pixel TGA images has been
1179 changed to match the behaviour of the GIMP. Previously the bit
1180 being set was treated as an opaque pixel, but one user reported a
1181 problem with loading such an image. I haven't been able to find any
1182 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1183 I'll match it's behaviour. See issue 114913 in the GIMP's
1184 bugzilla.

1341 - the mask for ICO/CUR images is now applied as an alpha channel to
1342 the returned image. For the old behaviour, supply ico_masked => 0
1343 to read() or read_multi(). This should be less confusing when
1344 using Imager as a general image processor.

1347Bug fixes:

1349 - in some cases it's possible for giflib/libungif to return color
1350 indexes outside the range of colors defined by the image's palette.
1351 We now expand the palette to match the indexes used.
1352 Thanks to Gabriel Vasseur for reporting this.

1357 - to avoid confusion, channels not present in the image are returned as
1358 zero by getscanline(). This has no effect on the C level i_glin()
1359 and i_glinf() API functions which continue to not set the unused
1360 channels.

1502Imager 0.55 - 16 Dec 2006
1503===========
1504
1505This is primarily a bug fix release.
1506
1507Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1508
1509There is one new feature:
1510
1511 - the Win32 font driver now supports UTF8 (RT 22166)
1512 http://www.cpanforum.com/threads/3276
1513 http://rt.cpan.org/Ticket/Display.html?id=22166
1514
1515Several bugs were fixed:
1516
1517 - the string() method would not output the string "0"
1518 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1519
1520 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1521 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1522
1523 - the gif_disposal and gif_user_input tags weren't being read from
1524 the file correctly
1525 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1526
1527 - gif.c was failing to build under MSVC
1528 http://rt.cpan.org/Ticket/Display.html?id=23922
1529
1530 - in some cases strings passed to the string() method were treated as
1531 terminated by NUL (chr 0)
1532 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1533
1534 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1535 that's the default build name for zlib on Win32.
1536 http://rt.cpan.org/Ticket/Display.html?id=23064
1537
1538 - search $Config{incpath} for headers too, which we should have been
1539 doing all along.
1540
1541Win32 font driver fixes:
1542
1543 - the global descent value from bounding box was the wrong sign
1544 http://www.cpanforum.com/threads/3276
1545
1546 - if the first or last glyph overflowed the left or right side of the
1547 advance width they would be clipped
1548
1549
1550Imager 0.54 - 14 Sep 2006
1551===========
1552
1553This is primarily a feature release:
1554
1555 - a new qtype value 'mixing' has been added to the scale()
1556 method. This is faster than 'normal', slower than 'preview'. This
1557 is based on the method used by pnmscale, and seems to produce less
1558 blurry results than normal.
1559 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1560
1561 - the rubthrough() method can now render onto images with an alpha
1562 channel.
1563 http://rt.cpan.org/Ticket/Display.html?id=20678
1564
1565 - the read_multi() method now falls back to calling doing a single
1566 image read via the read() method and write_multi() will now fall
1567 back to calling write() if a single image is supplied. This means
1568 you can simply call the read_multi() or write_multi() functions
1569 without having to check if the type is formatted by that method.
1570 http://rt.cpan.org/Ticket/Display.html?id=19457
1571 http://rt.cpan.org/Ticket/Display.html?id=19458
1572
1573 - the GIF loop extension can now be written. If you don't have
1574 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1575 should upgrade.
1576 http://rt.cpan.org/Ticket/Display.html?id=21185
1577
1578 - getscanline() and setscanline() can now read/write palette index
1579 based data from/to the image for paletted images, by setting type to
1580 'index'.
1581 http://rt.cpan.org/Ticket/Display.html?id=20338
1582
1583 - we no longer hassle you to disable GIF support
1584 http://rt.cpan.org/Ticket/Display.html?id=20687
1585
1586 - minor documentation fixes
1587
1588
1589Imager 0.53 - 26 Jul 2006
1590===========
1591
1592This is a bugfix release.
1593
1594Some test code was left in a code path not covered by the test
1595suite. A test was added to cover this code path and the test code was
1596removed.

1599
1600Imager 0.52 - 25 Jul 2006
1601===========
1602
1603This is primarily a feature release, but contains a fair few bug
1604fixes, new features:
1605
1606 - ability to read and write MS Windows ICO and CUR files
1607
1608 - you can now add file format plugins to support new file formats
1609
1610 - add POD coverage tests
1611
1612 - setcolors() and addcolors() now accept color names and so on
1613 instead of requiring Imager::Color objects.
1614 http://rt.cpan.org/Ticket/Display.html?id=20056
1615
1616 - flood_fill() can now fill to a specified border color instead of
1617 just to the area the same color as the seed.
1618 http://rt.cpan.org/Ticket/Display.html?id=19618
1619
1620
1621Bug fixes:
1622
1623 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1624 calculating the advance width.
1625 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1626
1627 - bounding_box for the T1 driver wasn't including leading and
1628 trailing spaces in the bounding box as the other drivers did, it also
1629 produced strange results for empty strings or strings containing only
1630 spaces
1631
1632 - when reading CMYK jpeg images they were being transferred to the
1633 image object as is, producing a four channel image. It only looked ok
1634 due to an old still unfixed Photoshop bug. We now convert from the
1635 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1636 http://rt.cpan.org/Ticket/Display.html?id=20416
1637
1638 - reading a CYMK TIFF would result in a 4 channel image, reading any
1639 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1640 result in an error.
1641 http://rt.cpan.org/Ticket/Display.html?id=20415
1642
1643 - added /usr/local/include to the default include search path, since
1644 we were already searching /usr/local/lib for libraries.
1645
1646And various minor fixes and documentation updates.
1647
1648
1649Imager 0.51 - 23 Apr 2006
1650===========

1653 a crash
1654 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1655
1656 - fix mis-processing of the src_maxx and src_maxy parameters of the

1666===========
1667

1669 or 4 channel image to jpeg or a 2 channel image to tga where the
1670 output is an in-memeory buffer.
