3Imager 0.90 - unreleased
4===========
5
6Bug fixes:
7
8 - Imager::Test::is_imaged() attempted to process an "epsilon"
9 parameter but the prototype didn't allow for the extra parameter.
10 Corrected the prototype.
11
29b38678
TC
12 - when downconverting samples (eg. from floating point to 8 bit)
13 Imager now rounds the sample value rather than attempting to
14 allocate input values over output values equally. The old
15 behaviour had the probably surprising effect of converting a
16 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
17 2.
18 This may result in slightly different 8 or 16-bit output images.
19
e2a86bac
TC
20 - BI_BITFIELD BMP images were handled incorrectly, both in
21 incorrectly calculating the space required for the masks and in
22 processing the image data itself.
23 https://rt.cpan.org/Ticket/Display.html?id=76736
24
25 - some odd width BMP BI_RLE4 images use run lengths that run one off
26 the edge of the image. Imager now allows this, discarding the
27 extra column.
28
29 - odd length RLE4 runs in BMP images were decoded incorrectly.

31Imager 0.89 - 18 Mar 2012
32===========
33
34Bug fixes:
35
93eab01e
TC
36 - getpixel(..., type => "float") and the API i_gpixf() have been
37 broken on paletted images since they were implemented.
38 https://rt.cpan.org/Ticket/Display.html?id=75258

TC
40Other changes:
41
61be9694
TC
42 - links in the METHOD INDEX now point at the method documentation
43 rather than the heading you can find them under.
44 https://rt.cpan.org/Ticket/Display.html?id=71495
45
a5919365
TC
46 - Imager (and the bundled dynamic modules) no longer fallback to
47 using DynaLoader if loading via XSLoader fails.
48 For the bundled modules this could hide useful error messages.
49 https://rt.cpan.org/Ticket/Display.html?id=75560
50
335078fc
TC
51 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
52 buffer in the array of allocations, but just stores the filename
53 pointer and line number.

56Imager 0.88 - 22 Feb 2012
57===========
58
43bef43b
TC
59 - describe how to build libgif etc on OS X in such a way as to be
60 compatible with a fat binary perl (such as the system perl), in
61 README.
62 https://rt.cpan.org/Ticket/Display.html?id=73371
63
69675eef
TC
64 - update the change notes for 0.77_01 to indicate that libungif
65 support was removed.
66
d4056453
TC
67 - add some other imaging modules to SEE ALSO
68 https://rt.cpan.org/Ticket/Display.html?id=73906
69
3b7f10da
TC
70 - note that the generator of the apparently non-DFSG-free postscript
71 in MMOne.pfb is a Debian package.
72
02323e69
TC
73 - setsamples() is now a true complement to getsamples() - it can
74 write 8-bit or floating point samples from a scalar or array
75 reference. This adds i_psamp() and i_psampf() to the C level API.
76
77 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
78 changed to make better use of the typemap, but these aren't part of
79 the perl level API anyway. There were no changes to the C level
80 interfaces to these functions.
81
2a27eeff
TC
82 - getpixel() and setpixel() now accept a mix of scalar and array
83 references for the x and y parameters, and unequal array lengths is
84 no longer an error.
85 https://rt.cpan.org/Ticket/Display.html?id=73697
86

87Bug fixes:
88
89 - correctly calculate the size of a rotated image
90 https://rt.cpan.org/Ticket/Display.html?id=69261

92 - fix incorrect rounding of color values for matrix_transform() and
93 rotate().
94 https://rt.cpan.org/Ticket/Display.html?id=69261
95
5091168a
TC
96 - Win32 text output is now done in normal combine mode, the alpha
97 component of the color is now significant.
98 https://rt.cpan.org/Ticket/Display.html?id=70014
99
fa0b1452
TC
100 - remove long unused gif case from read()
101 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
102
7640e3bb
TC
103 - the getsamples() target parameter was being treated as a hashref
104 when it's meant to be an array reference.
105 https://rt.cpan.org/Ticket/Display.html?id=74882
106
2a27eeff
TC
107 - getpixel() and setpixel() now returns an empty list when invalid
108 parameters are supplied.
109 Invalid values for type now result in an error for getpixel().

127
4f21e06e
TC
128 - make the error message from read() or read_multi() when they can't
129 identify the file type match reality.
130 https://rt.cpan.org/Ticket/Display.html?id=72475
131
132 - read() now uses $FORMATGUESS if it can't determine the file type
133 based on the file header, to match read_multi().
134
135 - re-work and add tests for def_guess_type(). def_guess_type() no
136 longer returns any random file extension as the file type.
137
5e9a7fbd
TC
138 - add gray4, gray16 and gray as presets for make_colors.

147
a044f2c6
TC
148 - fix i_render_color() to properly draw in "normal" mode - ie. when
149 writing to a 1 or 3 channel image the second or fourth channel of
150 the source color was being ignored, it is now significant.

181
f35d1231
TC
182 - add extra ppport.h configuration to support older perls.
183
954ac5d1
TC
184 - depend on Scalar::Util, since we use it and older perls don't have
185 it.
186
5efba0c6
TC
187 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
188 to synthesize it from overloaded "".
189
73e3ff55
TC
190 - use T1_StrError() for error messages on modern libt1
191 https://rt.cpan.org/Ticket/Display.html?id=69879
192
193 - actually load the font rather than just adding it to the catalog on
194 creation.
195
196 - Imager::Font->new now produces better error messages for the T1
197 engine.
198
6e938c74
TC
199 - the font has_chars() method now returns perl's true and false
200 values in list context rather than integers, which should be more
201 efficient.
202 https://rt.cpan.org/Ticket/Display.html?id=69158
203
b934971a
TC
204 - the btm data structure used by the flood_fill code is now

81409c5e
TC
214 - make the APIRef synopsis ordering consistent, older versions of
215 perl could order it differently.
216 https://rt.cpan.org/Ticket/Display.html?id=71675
217
336ce474
TC
218 - we rely on Config.pm's d_vsnprintf as to whether we use
219 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
220 though it only has _ prefixed versions of these. Define our own
221 prefixed names on Win32.

31be6e9a 230Imager 0.85_01 - 10 Oct 2011
6d5c85a2 231==============
a7e32beb
TC
232
233 - add simple tests for the Imager::Test test_image generators
234
6d5c85a2
TC
235 - io_glue I/O buffering re-work:
236
237 - reorganize io_glue to do it's own buffering by default
238
239 - the unbuffered functions are available as i_io_raw_read() (or
240 raw_read() from perl) etc but are not recommended for typical
241 use.
242
243 - use the new i_io_peekn() when checking for file magic to avoid
244 seek, allowing Imager to detect the file type and read the file
245 from an unseekable stream (for formats that don't use random
246 access)
247
248 - added several new I/O layer API functions.
249
250 - fix the TGA performance problem, most noticably on Win32
251 https://rt.cpan.org/Ticket/Display.html?id=70037
252
253 - TIFF now uses wrapper functions of the correct types to avoid casts
254 https://rt.cpan.org/Ticket/Display.html?id=69912
255
256 - the callback IO object did its own buffering, controlled by the
257 maxbuffer parameter supplied to the read() and write() methods.
258 This buffering has been removed, to avoid redundancy with the
259 common io_glue buffering. This also avoids a bug in that code
260 which could rarely pass a zero length to the read callback and
261 then panic about the result.
262
263 - the callback IO object now tests the result of calling the close
264 callback, which should return true for success.
265
266 - the PNM reader did its own buffering. This buffering has been
267 removed to avoid redundancy with the common io_glue buffering.
268
269 - previously the read handlers for fd and callback I/O layers would
270 call the underlying interface (POSIX read or your supplied callback)
271 until it filled the buffer. It now only makes one call.
272
273 - added public constructors for I/O layer objects (see Imager::IO)
274
275 - all core file handlers now use the i_io_foo() wrappers to gain
276 access to buffered I/O rather than calling the I/O layer
277 callbacks directly.
278
279 - all core file handlers now check for error on close.
280
281 - Backward compatibility: if you hava custom file handlers, you can
282 use i_io_write() etc since they're available as macros in older
283 versions of Imager.
284
285 - eliminate the final remnants of io_glue_commit_types().
286
287 - bump IMAGER_API_VERSION, since the above may break assumptions.
288
289 - removed the long unused i_gen_reader() and i_gen_writer() utility
290 functions.

6ad7e4bc
TC
293===========
294
0c647c9a
TC
295The main changes in the release versus 0.84 are:
296
297 - on 64-bit systems, 64-bit types are consistently used for image
298 dimensions and co-ordinated, and for memory block sizes.
299
300 - handle IFD loops in TIFF files correctly. Previously this would
301 lead to an infinite loop.
302
6ad7e4bc
TC
303Bug fixes:
304
305 - fix the link in the getheight() entry in the method index

6b7197d0
TC
312
313Bug fixes:
314
315 - the image file limits set by set_file_limits() weren't being
316 checked when reading TIFF files.
317 https://rt.cpan.org/Ticket/Display.html?id=69915
318
5970bd39
TC
319 - Provide more information about file format module load errors on a
320 failed image file read() or write().
321 https://rt.cpan.org/Ticket/Display.html?id=69194
322
4ce3551c
TC
323 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
324 through TIFF images, since it checks for IFD loops.
325 https://rt.cpan.org/Ticket/Display.html?id=69914
326
a16bca6d
TC
327 - don't leak memory when out of range palette indexes are supplied to
328 setscanline().
329 https://rt.cpan.org/Ticket/Display.html?id=69242
330
331 - require a later version of CPAN::Meta to ensure JSON::PP and
332 CPAN::Meta::YAML are available.
333 https://rt.cpan.org/Ticket/Display.html?id=69008
334
ac575c5f
TC
335 - hoist the per-line calculations for the flines implementations, and

86c8d19a
TC
339 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use

350Imager 0.84_01 - 8 Aug 2011
351==============
352
353Development release as a sanity check for the types re-work.
8d14daab
TC
354
355Massive types re-work:
356
357 - the type used internally for pixel co-ordinates and image sizes is
358 now 64-bit on 64-bit platforms (at least sane ones).
359
360 - size_t is now used consistently for memory block sizes.
361
362 - since this changes the binary interface, the Imager API version has
363 been incremented. Any module that uses the API will need to be
364 rebuilt. In most cases that will be enough, but calls to any APIs
365 that take a pointer to image sizes may need source changes.
366
367 - you should be able to create very large images on 64-bit systems,
368 if you have enough memory. Successfully created a 32768 x 49192 x
369 3 channel image, filled with a tiled image and scaled it. The
370 unscaled image was also successfully saved to a JPEG.
371
372 - check the image size before attempting to write BMP, GIF, JPEG,
373 PNG, SGI, TGA, TIFF images.
374
375 - correctly handle reading TGA images over 32767 pixels wide or tall.
376
377Incidental changes:
378
379 - the gif_left and gif_top tags are now clamped to non-negative
380 values when writing a GIF image.
381
382 - removed dead callback read/write code
383
384The default maximum memory size when reading files is now 1G.

413 translation.
414 https://rt.cpan.org/Ticket/Display.html?id=68508
415
59c150a4
TC
416 - writing a paletted image to GIF wouldn't always use the colors
417 supplied (or generated, eg. via make_colors => "mono"), which was
418 confusing at best.
419 https://rt.cpan.org/Ticket/Display.html?id=67912

448
449 - compose() now returns a useful error message on a non-positive
450 opacity.

456===========
457
458Bug fixes:
459
460 - eliminate calls to i_has_format() from the test suite, since it's
461 no longer a useful way to check for file format support. Eliminate
462 i_has_format() from the functions exposed via XS.

1022This release primarily contains changes to improve ease of use -
1023rather than you having to convert images to the appropriate number of
1024channels, Imager handles it internally. How to handle drawing colors
1025and the default combine mode is a thornier problem left for some other
1026release.

TC
1031 - moved the imtoc.perl code into Imager::Preprocess
1032
1033 - paste() and rubthrough() now adapt the source image data to the
1034 destination, so you can now safely paste/rubthrough from greyscale
1035 images to color images or back, or from alpha channel images to
1036 noalpha channels or back.
1037 https://rt.cpan.org/Ticket/Display.html?id=30908
1038
1039 - rubthrough() now falls back to pasting when the source doesn't have
1040 an alpha channel. This effectively treats the source as having a
1041 max alpha channel, the right thing to do.
1042 http://rt.cpan.org/Ticket/Display.html?id=29944
1043
1044 - re-worked most of the area filling code to use a common set of
1045 functions when filling.
1046 Corrected normal combine mode.
1047 Rewrote most of the combine modes to match the way the SVG draft
1048 defines them with respect to a translucent source and destination.
1049 Added tests for translucent source and destination.
1050 Added tests to check 8-bit/sample and double/sample combines work
1051 similarly.

1090 - handling of the left-over bit for 16-bit/pixel TGA images has been
1091 changed to match the behaviour of the GIMP. Previously the bit
1092 being set was treated as an opaque pixel, but one user reported a
1093 problem with loading such an image. I haven't been able to find any
1094 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1095 I'll match it's behaviour. See issue 114913 in the GIMP's
1096 bugzilla.

1106 - the old dynaload code used Mach API functions to load dynamic
1107 libraries on Mac OS X. These APIs have been deprecated in OS X
1108 10.5 and were causing some build problems.

1110 will need version 10.3 or later of OS X.

1342 - reworked library probing, we can now set more than one probe
1343 function for a library. Disabled the default (non-freetype-config)
1344 library probe and added an extra probe function that searches for
1345 both ft2build.h and whatever it includes, and adds -I as needed.
1346 Hopefully this will fix build problems like

1414Imager 0.55 - 16 Dec 2006
1415===========
1416
1417This is primarily a bug fix release.
1418
1419Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1420
1421There is one new feature:
1422
1423 - the Win32 font driver now supports UTF8 (RT 22166)
1424 http://www.cpanforum.com/threads/3276
1425 http://rt.cpan.org/Ticket/Display.html?id=22166
1426
1427Several bugs were fixed:
1428
1429 - the string() method would not output the string "0"
1430 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1431
1432 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1433 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1434
1435 - the gif_disposal and gif_user_input tags weren't being read from
1436 the file correctly
1437 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1438
1439 - gif.c was failing to build under MSVC
1440 http://rt.cpan.org/Ticket/Display.html?id=23922
1441
1442 - in some cases strings passed to the string() method were treated as
1443 terminated by NUL (chr 0)
1444 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1445
1446 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1447 that's the default build name for zlib on Win32.
1448 http://rt.cpan.org/Ticket/Display.html?id=23064
1449
1450 - search $Config{incpath} for headers too, which we should have been
1451 doing all along.
1452
1453Win32 font driver fixes:
1454
1455 - the global descent value from bounding box was the wrong sign
1456 http://www.cpanforum.com/threads/3276
1457
1458 - if the first or last glyph overflowed the left or right side of the
1459 advance width they would be clipped
1460
1461
1462Imager 0.54 - 14 Sep 2006
1463===========
1464
1465This is primarily a feature release:
1466
1467 - a new qtype value 'mixing' has been added to the scale()
1468 method. This is faster than 'normal', slower than 'preview'. This
1469 is based on the method used by pnmscale, and seems to produce less
1470 blurry results than normal.
1471 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1472
1473 - the rubthrough() method can now render onto images with an alpha
1474 channel.
1475 http://rt.cpan.org/Ticket/Display.html?id=20678
1476
1477 - the read_multi() method now falls back to calling doing a single
1478 image read via the read() method and write_multi() will now fall
1479 back to calling write() if a single image is supplied. This means
1480 you can simply call the read_multi() or write_multi() functions
1481 without having to check if the type is formatted by that method.
1482 http://rt.cpan.org/Ticket/Display.html?id=19457
1483 http://rt.cpan.org/Ticket/Display.html?id=19458
1484
1485 - the GIF loop extension can now be written. If you don't have
1486 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1487 should upgrade.
1488 http://rt.cpan.org/Ticket/Display.html?id=21185
1489
1490 - getscanline() and setscanline() can now read/write palette index
1491 based data from/to the image for paletted images, by setting type to
1492 'index'.
1493 http://rt.cpan.org/Ticket/Display.html?id=20338
1494
1495 - we no longer hassle you to disable GIF support
1496 http://rt.cpan.org/Ticket/Display.html?id=20687
1497
1498 - minor documentation fixes
1499
1500
1501Imager 0.53 - 26 Jul 2006
1502===========
1503
1504This is a bugfix release.
1505
1506Some test code was left in a code path not covered by the test
1507suite. A test was added to cover this code path and the test code was
1508removed.

1511
1512Imager 0.52 - 25 Jul 2006
1513===========
1514
1515This is primarily a feature release, but contains a fair few bug
1516fixes, new features:
1517
1518 - ability to read and write MS Windows ICO and CUR files
1519
1520 - you can now add file format plugins to support new file formats
1521
1522 - add POD coverage tests
1523
1524 - setcolors() and addcolors() now accept color names and so on
1525 instead of requiring Imager::Color objects.
1526 http://rt.cpan.org/Ticket/Display.html?id=20056
1527
1528 - flood_fill() can now fill to a specified border color instead of
1529 just to the area the same color as the seed.
1530 http://rt.cpan.org/Ticket/Display.html?id=19618
1531
1532
1533Bug fixes:
1534
1535 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1536 calculating the advance width.
1537 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1538
1539 - bounding_box for the T1 driver wasn't including leading and
1540 trailing spaces in the bounding box as the other drivers did, it also
1541 produced strange results for empty strings or strings containing only
1542 spaces
1543
1544 - when reading CMYK jpeg images they were being transferred to the
1545 image object as is, producing a four channel image. It only looked ok
1546 due to an old still unfixed Photoshop bug. We now convert from the
1547 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1548 http://rt.cpan.org/Ticket/Display.html?id=20416
1549
1550 - reading a CYMK TIFF would result in a 4 channel image, reading any
1551 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1552 result in an error.
1553 http://rt.cpan.org/Ticket/Display.html?id=20415
1554
1555 - added /usr/local/include to the default include search path, since
1556 we were already searching /usr/local/lib for libraries.
1557
1558And various minor fixes and documentation updates.
1559
1560

1565 a crash
1566 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1567
1568 - fix mis-processing of the src_maxx and src_maxy parameters of the
1569 paste() method
1570 http://rt.cpan.org/Public/Bug/Display.html?id=18712

1582 output is an in-memeory buffer.

1584
1585 - fixes an incorrect pointer parameter in the PNG code
1586 http://rt.cpan.org/Public/Bug/Display.html?id=18051
