20Imager 0.90 - unreleased
21===========
22
23Bug fixes:
24
25 - Imager::Test::is_imaged() attempted to process an "epsilon"
26 parameter but the prototype didn't allow for the extra parameter.
27 Corrected the prototype.

TC
29 - when downconverting samples (eg. from floating point to 8 bit)
30 Imager now rounds the sample value rather than attempting to
31 allocate input values over output values equally. The old
32 behaviour had the probably surprising effect of converting a
33 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
34 2.
35 This may result in slightly different 8 or 16-bit output images.
36
e2a86bac
TC
37 - BI_BITFIELD BMP images were handled incorrectly, both in
38 incorrectly calculating the space required for the masks and in
39 processing the image data itself.
40 https://rt.cpan.org/Ticket/Display.html?id=76736
41
42 - some odd width BMP BI_RLE4 images use run lengths that run one off
43 the edge of the image. Imager now allows this, discarding the
44 extra column.
45
46 - odd length RLE4 runs in BMP images were decoded incorrectly.
47
82eb0687
TC
48 - pkg-config could sometimes return a library that was in a directory
49 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
50 If no -L is included in the pkg-config library information check if
51 EU::MM can find the library, and if not, search our configured
52 directories and insert that into the library flags.
53 https://rt.cpan.org/Ticket/Display.html?id=75869
54
de50f459
TC
55 - Imager::Probe can now probe for libraries with dependent libraries,
56 common for static linking, eg. libpng requires libz.
57 https://rt.cpan.org/Ticket/Display.html?id=74043
58
59 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
60
61 - added alternative probe configurations that try to link libz, to
62 handle a statically linked libpng.
63 https://rt.cpan.org/Ticket/Display.html?id=74043
64
65 - if a probe includes testcode, Imager::Probe now checks that code as
66 part of the process of checking each configuration rather than as a
67 post test of the found configuration. This allows alternate
68 configurations to be checked if a matching but non-working
69 configuration is found.
70 https://rt.cpan.org/Ticket/Display.html?id=74043
71
9d5ff8a6
TC
72Other changes:
73
74 - when reading or writing images via callbacks, the default callbacks
75 now push an error message indicating that a required callback was
76 called but not supplied.
77 https://rt.cpan.org/Ticket/Display.html?id=76782
78
79 - clarify which callbacks are required for reading and writing TIFF
80 images.
81
82 - improve logging for creation of callback I/O layers.
83
de50f459
TC
84 - a little more documentation for Imager::Probe.
85
594f5933
TC
86 - the i_get_file_background() and i_get_file_backgroundf() APIs now
87 return int to indicate whether the i_background tag was found.

90===========
91
92Bug fixes:
93

TC
94 - getpixel(..., type => "float") and the API i_gpixf() have been
95 broken on paletted images since they were implemented.

100 - links in the METHOD INDEX now point at the method documentation
101 rather than the heading you can find them under.
102 https://rt.cpan.org/Ticket/Display.html?id=71495
103
a5919365
TC
104 - Imager (and the bundled dynamic modules) no longer fallback to
105 using DynaLoader if loading via XSLoader fails.
106 For the bundled modules this could hide useful error messages.
107 https://rt.cpan.org/Ticket/Display.html?id=75560
108
335078fc
TC
109 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
110 buffer in the array of allocations, but just stores the filename
111 pointer and line number.

114Imager 0.88 - 22 Feb 2012
115===========
116
43bef43b
TC
117 - describe how to build libgif etc on OS X in such a way as to be
118 compatible with a fat binary perl (such as the system perl), in
119 README.
120 https://rt.cpan.org/Ticket/Display.html?id=73371
121
69675eef

122 - update the change notes for 0.77_01 to indicate that libungif
123 support was removed.
124

125 - add some other imaging modules to SEE ALSO
126 https://rt.cpan.org/Ticket/Display.html?id=73906
127
3b7f10da
TC
128 - note that the generator of the apparently non-DFSG-free postscript
129 in MMOne.pfb is a Debian package.
130
02323e69
TC
131 - setsamples() is now a true complement to getsamples() - it can
132 write 8-bit or floating point samples from a scalar or array
133 reference. This adds i_psamp() and i_psampf() to the C level API.
134
135 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
136 changed to make better use of the typemap, but these aren't part of
137 the perl level API anyway. There were no changes to the C level
138 interfaces to these functions.
139
2a27eeff
TC
140 - getpixel() and setpixel() now accept a mix of scalar and array
141 references for the x and y parameters, and unequal array lengths is
142 no longer an error.

153
5091168a

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

158 - remove long unused gif case from read()
159 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
160
7640e3bb
TC
161 - the getsamples() target parameter was being treated as a hashref
162 when it's meant to be an array reference.
163 https://rt.cpan.org/Ticket/Display.html?id=74882
164
2a27eeff
TC
165 - getpixel() and setpixel() now returns an empty list when invalid
166 parameters are supplied.
167 Invalid values for type now result in an error for getpixel().

TC
186 - make the error message from read() or read_multi() when they can't
187 identify the file type match reality.
188 https://rt.cpan.org/Ticket/Display.html?id=72475
189
190 - read() now uses $FORMATGUESS if it can't determine the file type
191 based on the file header, to match read_multi().
192
193 - re-work and add tests for def_guess_type(). def_guess_type() no
194 longer returns any random file extension as the file type.
195

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

241
954ac5d1

243 it.
244
5efba0c6
TC
245 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
246 to synthesize it from overloaded "".
247
73e3ff55
TC
248 - use T1_StrError() for error messages on modern libt1
249 https://rt.cpan.org/Ticket/Display.html?id=69879
250
251 - actually load the font rather than just adding it to the catalog on
252 creation.
253
254 - Imager::Font->new now produces better error messages for the T1
255 engine.
256
6e938c74
TC
257 - the font has_chars() method now returns perl's true and false
258 values in list context rather than integers, which should be more
259 efficient.

273 perl could order it differently.
274 https://rt.cpan.org/Ticket/Display.html?id=71675
275
336ce474
TC
276 - we rely on Config.pm's d_vsnprintf as to whether we use
277 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
278 though it only has _ prefixed versions of these. Define our own
279 prefixed names on Win32.

31be6e9a 288Imager 0.85_01 - 10 Oct 2011
6d5c85a2 289==============
a7e32beb
TC
290
291 - add simple tests for the Imager::Test test_image generators
292
6d5c85a2
TC
293 - io_glue I/O buffering re-work:
294
295 - reorganize io_glue to do it's own buffering by default
296
297 - the unbuffered functions are available as i_io_raw_read() (or
298 raw_read() from perl) etc but are not recommended for typical
299 use.
300
301 - use the new i_io_peekn() when checking for file magic to avoid
302 seek, allowing Imager to detect the file type and read the file
303 from an unseekable stream (for formats that don't use random
304 access)
305
306 - added several new I/O layer API functions.
307
308 - fix the TGA performance problem, most noticably on Win32
309 https://rt.cpan.org/Ticket/Display.html?id=70037
310
311 - TIFF now uses wrapper functions of the correct types to avoid casts
312 https://rt.cpan.org/Ticket/Display.html?id=69912
313
314 - the callback IO object did its own buffering, controlled by the
315 maxbuffer parameter supplied to the read() and write() methods.
316 This buffering has been removed, to avoid redundancy with the
317 common io_glue buffering. This also avoids a bug in that code
318 which could rarely pass a zero length to the read callback and
319 then panic about the result.
320
321 - the callback IO object now tests the result of calling the close
322 callback, which should return true for success.
323
324 - the PNM reader did its own buffering. This buffering has been
325 removed to avoid redundancy with the common io_glue buffering.
326
327 - previously the read handlers for fd and callback I/O layers would
328 call the underlying interface (POSIX read or your supplied callback)
329 until it filled the buffer. It now only makes one call.
330
331 - added public constructors for I/O layer objects (see Imager::IO)
332
333 - all core file handlers now use the i_io_foo() wrappers to gain
334 access to buffered I/O rather than calling the I/O layer
335 callbacks directly.
336
337 - all core file handlers now check for error on close.
338
339 - Backward compatibility: if you hava custom file handlers, you can
340 use i_io_write() etc since they're available as macros in older
341 versions of Imager.
342
343 - eliminate the final remnants of io_glue_commit_types().
344
345 - bump IMAGER_API_VERSION, since the above may break assumptions.
346
347 - removed the long unused i_gen_reader() and i_gen_writer() utility
348 functions.

TC
351===========
352
0c647c9a
TC
353The main changes in the release versus 0.84 are:
354
355 - on 64-bit systems, 64-bit types are consistently used for image
356 dimensions and co-ordinated, and for memory block sizes.
357
358 - handle IFD loops in TIFF files correctly. Previously this would
359 lead to an infinite loop.
360

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

408Imager 0.84_01 - 8 Aug 2011
409==============
410
411Development release as a sanity check for the types re-work.
8d14daab
TC
412
413Massive types re-work:
414
415 - the type used internally for pixel co-ordinates and image sizes is
416 now 64-bit on 64-bit platforms (at least sane ones).
417
418 - size_t is now used consistently for memory block sizes.
419
420 - since this changes the binary interface, the Imager API version has
421 been incremented. Any module that uses the API will need to be
422 rebuilt. In most cases that will be enough, but calls to any APIs
423 that take a pointer to image sizes may need source changes.
424
425 - you should be able to create very large images on 64-bit systems,
426 if you have enough memory. Successfully created a 32768 x 49192 x
427 3 channel image, filled with a tiled image and scaled it. The
428 unscaled image was also successfully saved to a JPEG.
429
430 - check the image size before attempting to write BMP, GIF, JPEG,
431 PNG, SGI, TGA, TIFF images.
432
433 - correctly handle reading TGA images over 32767 pixels wide or tall.
434
435Incidental changes:
436
437 - the gif_left and gif_top tags are now clamped to non-negative
438 values when writing a GIF image.
439
440 - removed dead callback read/write code
441
442The default maximum memory size when reading files is now 1G.

1080This release primarily contains changes to improve ease of use -
1081rather than you having to convert images to the appropriate number of

1089 - moved the imtoc.perl code into Imager::Preprocess

1091 - paste() and rubthrough() now adapt the source image data to the
1092 destination, so you can now safely paste/rubthrough from greyscale
1093 images to color images or back, or from alpha channel images to
1094 noalpha channels or back.
1095 https://rt.cpan.org/Ticket/Display.html?id=30908
1096
1097 - rubthrough() now falls back to pasting when the source doesn't have
1098 an alpha channel. This effectively treats the source as having a
1099 max alpha channel, the right thing to do.
1100 http://rt.cpan.org/Ticket/Display.html?id=29944
1101
1102 - re-worked most of the area filling code to use a common set of
1103 functions when filling.
1104 Corrected normal combine mode.
1105 Rewrote most of the combine modes to match the way the SVG draft
1106 defines them with respect to a translucent source and destination.
1107 Added tests for translucent source and destination.
1108 Added tests to check 8-bit/sample and double/sample combines work
1109 similarly.

1148 - handling of the left-over bit for 16-bit/pixel TGA images has been
1149 changed to match the behaviour of the GIMP. Previously the bit
1150 being set was treated as an opaque pixel, but one user reported a
1151 problem with loading such an image. I haven't been able to find any
1152 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1153 I'll match it's behaviour. See issue 114913 in the GIMP's
1154 bugzilla.

1164 - the old dynaload code used Mach API functions to load dynamic
1165 libraries on Mac OS X. These APIs have been deprecated in OS X

1472Imager 0.55 - 16 Dec 2006
1473===========
1474
1475This is primarily a bug fix release.
1476
1477Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1478
1479There is one new feature:
1480
1481 - the Win32 font driver now supports UTF8 (RT 22166)
1482 http://www.cpanforum.com/threads/3276
1483 http://rt.cpan.org/Ticket/Display.html?id=22166
1484
1485Several bugs were fixed:
1486
1487 - the string() method would not output the string "0"
1488 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1489
1490 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1491 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1492
1493 - the gif_disposal and gif_user_input tags weren't being read from
1494 the file correctly
1495 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1496
1497 - gif.c was failing to build under MSVC
1498 http://rt.cpan.org/Ticket/Display.html?id=23922
1499
1500 - in some cases strings passed to the string() method were treated as
1501 terminated by NUL (chr 0)
1502 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1503
1504 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1505 that's the default build name for zlib on Win32.
1506 http://rt.cpan.org/Ticket/Display.html?id=23064
1507
1508 - search $Config{incpath} for headers too, which we should have been
1509 doing all along.
1510
1511Win32 font driver fixes:
1512
1513 - the global descent value from bounding box was the wrong sign
1514 http://www.cpanforum.com/threads/3276
1515
1516 - if the first or last glyph overflowed the left or right side of the
1517 advance width they would be clipped
1518
1519
1520Imager 0.54 - 14 Sep 2006
1521===========
1522
1523This is primarily a feature release:
1524
1525 - a new qtype value 'mixing' has been added to the scale()
1526 method. This is faster than 'normal', slower than 'preview'. This
1527 is based on the method used by pnmscale, and seems to produce less
1528 blurry results than normal.
1529 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1530
1531 - the rubthrough() method can now render onto images with an alpha
1532 channel.
1533 http://rt.cpan.org/Ticket/Display.html?id=20678
1534
1535 - the read_multi() method now falls back to calling doing a single
1536 image read via the read() method and write_multi() will now fall
1537 back to calling write() if a single image is supplied. This means
1538 you can simply call the read_multi() or write_multi() functions
1539 without having to check if the type is formatted by that method.
1540 http://rt.cpan.org/Ticket/Display.html?id=19457
1541 http://rt.cpan.org/Ticket/Display.html?id=19458
1542
1543 - the GIF loop extension can now be written. If you don't have
1544 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1545 should upgrade.
1546 http://rt.cpan.org/Ticket/Display.html?id=21185
1547
1548 - getscanline() and setscanline() can now read/write palette index
1549 based data from/to the image for paletted images, by setting type to
1550 'index'.
1551 http://rt.cpan.org/Ticket/Display.html?id=20338
1552
1553 - we no longer hassle you to disable GIF support
1554 http://rt.cpan.org/Ticket/Display.html?id=20687
1555
1556 - minor documentation fixes
1557
1558
1559Imager 0.53 - 26 Jul 2006
1560===========
1561
1562This is a bugfix release.
1563
1564Some test code was left in a code path not covered by the test
1565suite. A test was added to cover this code path and the test code was
1566removed.

1570Imager 0.52 - 25 Jul 2006
1571===========
1572
1573This is primarily a feature release, but contains a fair few bug
1574fixes, new features:
1575
1576 - ability to read and write MS Windows ICO and CUR files
1577
1578 - you can now add file format plugins to support new file formats
1579
1580 - add POD coverage tests
1581
1582 - setcolors() and addcolors() now accept color names and so on
1583 instead of requiring Imager::Color objects.
1584 http://rt.cpan.org/Ticket/Display.html?id=20056
1585
1586 - flood_fill() can now fill to a specified border color instead of
1587 just to the area the same color as the seed.
1588 http://rt.cpan.org/Ticket/Display.html?id=19618
1589
1590
1591Bug fixes:
1592
1593 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1594 calculating the advance width.
1595 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1596
1597 - bounding_box for the T1 driver wasn't including leading and
1598 trailing spaces in the bounding box as the other drivers did, it also
1599 produced strange results for empty strings or strings containing only
1600 spaces
1601
1602 - when reading CMYK jpeg images they were being transferred to the
1603 image object as is, producing a four channel image. It only looked ok
1604 due to an old still unfixed Photoshop bug. We now convert from the
1605 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1606 http://rt.cpan.org/Ticket/Display.html?id=20416
1607
1608 - reading a CYMK TIFF would result in a 4 channel image, reading any
1609 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1610 result in an error.
1611 http://rt.cpan.org/Ticket/Display.html?id=20415
1612
1613 - added /usr/local/include to the default include search path, since
1614 we were already searching /usr/local/lib for libraries.
1615
1616And various minor fixes and documentation updates.
1617
1618
1619Imager 0.51 - 23 Apr 2006

1625
1626 - fix mis-processing of the src_maxx and src_maxy parameters of the

1640 output is an in-memeory buffer.
