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

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.

20Imager 0.89 - 18 Mar 2012
21===========
22
23Bug fixes:
24
93eab01e
TC
25 - getpixel(..., type => "float") and the API i_gpixf() have been
26 broken on paletted images since they were implemented.

29Other changes:

61be9694
TC
31 - links in the METHOD INDEX now point at the method documentation
32 rather than the heading you can find them under.
33 https://rt.cpan.org/Ticket/Display.html?id=71495
34
a5919365
TC
35 - Imager (and the bundled dynamic modules) no longer fallback to
36 using DynaLoader if loading via XSLoader fails.
37 For the bundled modules this could hide useful error messages.
38 https://rt.cpan.org/Ticket/Display.html?id=75560
39
335078fc
TC
40 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
41 buffer in the array of allocations, but just stores the filename
42 pointer and line number.

45Imager 0.88 - 22 Feb 2012
46===========
47
43bef43b
TC
48 - describe how to build libgif etc on OS X in such a way as to be
49 compatible with a fat binary perl (such as the system perl), in
50 README.
51 https://rt.cpan.org/Ticket/Display.html?id=73371
52
69675eef
TC
53 - update the change notes for 0.77_01 to indicate that libungif
54 support was removed.
55
d4056453
TC
56 - add some other imaging modules to SEE ALSO
57 https://rt.cpan.org/Ticket/Display.html?id=73906
58
3b7f10da
TC
59 - note that the generator of the apparently non-DFSG-free postscript
60 in MMOne.pfb is a Debian package.
61
02323e69
TC
62 - setsamples() is now a true complement to getsamples() - it can
63 write 8-bit or floating point samples from a scalar or array
64 reference. This adds i_psamp() and i_psampf() to the C level API.
65
66 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
67 changed to make better use of the typemap, but these aren't part of
68 the perl level API anyway. There were no changes to the C level
69 interfaces to these functions.
70
2a27eeff
TC
71 - getpixel() and setpixel() now accept a mix of scalar and array
72 references for the x and y parameters, and unequal array lengths is
73 no longer an error.
74 https://rt.cpan.org/Ticket/Display.html?id=73697

84
5091168a
TC
85 - Win32 text output is now done in normal combine mode, the alpha
86 component of the color is now significant.

88
fa0b1452
TC
89 - remove long unused gif case from read()
90 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
91
7640e3bb
TC
92 - the getsamples() target parameter was being treated as a hashref
93 when it's meant to be an array reference.
94 https://rt.cpan.org/Ticket/Display.html?id=74882
95
2a27eeff
TC
96 - getpixel() and setpixel() now returns an empty list when invalid
97 parameters are supplied.
98 Invalid values for type now result in an error for getpixel().

117 - make the error message from read() or read_multi() when they can't
118 identify the file type match reality.
119 https://rt.cpan.org/Ticket/Display.html?id=72475
120
121 - read() now uses $FORMATGUESS if it can't determine the file type
122 based on the file header, to match read_multi().
123
124 - re-work and add tests for def_guess_type(). def_guess_type() no
125 longer returns any random file extension as the file type.

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

TC
171 - add extra ppport.h configuration to support older perls.
172
954ac5d1
TC
173 - depend on Scalar::Util, since we use it and older perls don't have
174 it.
175
5efba0c6
TC
176 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
177 to synthesize it from overloaded "".
178
73e3ff55
TC
179 - use T1_StrError() for error messages on modern libt1
180 https://rt.cpan.org/Ticket/Display.html?id=69879
181
182 - actually load the font rather than just adding it to the catalog on
183 creation.
184
185 - Imager::Font->new now produces better error messages for the T1
186 engine.
187
6e938c74
TC
188 - the font has_chars() method now returns perl's true and false
189 values in list context rather than integers, which should be more
190 efficient.

203 - make the APIRef synopsis ordering consistent, older versions of
204 perl could order it differently.
205 https://rt.cpan.org/Ticket/Display.html?id=71675
206
336ce474
TC
207 - we rely on Config.pm's d_vsnprintf as to whether we use
208 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
209 though it only has _ prefixed versions of these. Define our own
210 prefixed names on Win32.

31be6e9a 219Imager 0.85_01 - 10 Oct 2011
6d5c85a2 220==============
a7e32beb
TC
221
222 - add simple tests for the Imager::Test test_image generators
223
6d5c85a2
TC
224 - io_glue I/O buffering re-work:
225
226 - reorganize io_glue to do it's own buffering by default
227
228 - the unbuffered functions are available as i_io_raw_read() (or
229 raw_read() from perl) etc but are not recommended for typical
230 use.
231
232 - use the new i_io_peekn() when checking for file magic to avoid
233 seek, allowing Imager to detect the file type and read the file
234 from an unseekable stream (for formats that don't use random
235 access)
236
237 - added several new I/O layer API functions.
238
239 - fix the TGA performance problem, most noticably on Win32
240 https://rt.cpan.org/Ticket/Display.html?id=70037
241
242 - TIFF now uses wrapper functions of the correct types to avoid casts
243 https://rt.cpan.org/Ticket/Display.html?id=69912
244
245 - the callback IO object did its own buffering, controlled by the
246 maxbuffer parameter supplied to the read() and write() methods.
247 This buffering has been removed, to avoid redundancy with the
248 common io_glue buffering. This also avoids a bug in that code
249 which could rarely pass a zero length to the read callback and
250 then panic about the result.
251
252 - the callback IO object now tests the result of calling the close
253 callback, which should return true for success.
254
255 - the PNM reader did its own buffering. This buffering has been
256 removed to avoid redundancy with the common io_glue buffering.
257
258 - previously the read handlers for fd and callback I/O layers would
259 call the underlying interface (POSIX read or your supplied callback)
260 until it filled the buffer. It now only makes one call.
261
262 - added public constructors for I/O layer objects (see Imager::IO)
263
264 - all core file handlers now use the i_io_foo() wrappers to gain
265 access to buffered I/O rather than calling the I/O layer
266 callbacks directly.
267
268 - all core file handlers now check for error on close.
269
270 - Backward compatibility: if you hava custom file handlers, you can
271 use i_io_write() etc since they're available as macros in older
272 versions of Imager.
273
274 - eliminate the final remnants of io_glue_commit_types().
275
276 - bump IMAGER_API_VERSION, since the above may break assumptions.
277
278 - removed the long unused i_gen_reader() and i_gen_writer() utility
279 functions.

6ad7e4bc
TC
282===========
283
0c647c9a
TC
284The main changes in the release versus 0.84 are:
285
286 - on 64-bit systems, 64-bit types are consistently used for image
287 dimensions and co-ordinated, and for memory block sizes.
288
289 - handle IFD loops in TIFF files correctly. Previously this would
290 lead to an infinite loop.
291
6ad7e4bc
TC
292Bug fixes:

311
4ce3551c
TC
312 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
313 through TIFF images, since it checks for IFD loops.
314 https://rt.cpan.org/Ticket/Display.html?id=69914
315
a16bca6d

316 - don't leak memory when out of range palette indexes are supplied to
317 setscanline().
318 https://rt.cpan.org/Ticket/Display.html?id=69242
319
320 - require a later version of CPAN::Meta to ensure JSON::PP and

339Imager 0.84_01 - 8 Aug 2011
340==============
341
342Development release as a sanity check for the types re-work.
8d14daab
TC
343
344Massive types re-work:
345
346 - the type used internally for pixel co-ordinates and image sizes is
347 now 64-bit on 64-bit platforms (at least sane ones).
348
349 - size_t is now used consistently for memory block sizes.
350
351 - since this changes the binary interface, the Imager API version has
352 been incremented. Any module that uses the API will need to be
353 rebuilt. In most cases that will be enough, but calls to any APIs
354 that take a pointer to image sizes may need source changes.
355
356 - you should be able to create very large images on 64-bit systems,
357 if you have enough memory. Successfully created a 32768 x 49192 x
358 3 channel image, filled with a tiled image and scaled it. The
359 unscaled image was also successfully saved to a JPEG.
360
361 - check the image size before attempting to write BMP, GIF, JPEG,
362 PNG, SGI, TGA, TIFF images.
363
364 - correctly handle reading TGA images over 32767 pixels wide or tall.
365
366Incidental changes:
367
368 - the gif_left and gif_top tags are now clamped to non-negative
369 values when writing a GIF image.
370
371 - removed dead callback read/write code
372
373The default maximum memory size when reading files is now 1G.

59c150a4

405 - writing a paletted image to GIF wouldn't always use the colors

983 - Possible security issue: The floating point sample path for image

990 true when read() or write() is supplied with an fh parameter.
991 http://rt.cpan.org/Ticket/Display.html?id=35139

993 - i_scale_axis() wasn't checking the result of i_img_new_ch()
994 resulting in a SIGSEGV when attempting to scale an image to a size
995 too large to fit in memory. This is a NULL pointer access issue,
996 not a buffer overflow.
997 Added a check for the failure.
998 scale_calculate() (and hence scale()) will now fail if any of the
999 scale size parameters are a reference.

1011This release primarily contains changes to improve ease of use -
1012rather than you having to convert images to the appropriate number of
1013channels, Imager handles it internally. How to handle drawing colors
1014and the default combine mode is a thornier problem left for some other
1015release.

TC
1020 - moved the imtoc.perl code into Imager::Preprocess
1021
1022 - paste() and rubthrough() now adapt the source image data to the
1023 destination, so you can now safely paste/rubthrough from greyscale
1024 images to color images or back, or from alpha channel images to
1025 noalpha channels or back.
1026 https://rt.cpan.org/Ticket/Display.html?id=30908
1027
1028 - rubthrough() now falls back to pasting when the source doesn't have
1029 an alpha channel. This effectively treats the source as having a
1030 max alpha channel, the right thing to do.
1031 http://rt.cpan.org/Ticket/Display.html?id=29944
1032
1033 - re-worked most of the area filling code to use a common set of
1034 functions when filling.
1035 Corrected normal combine mode.
1036 Rewrote most of the combine modes to match the way the SVG draft
1037 defines them with respect to a translucent source and destination.
1038 Added tests for translucent source and destination.
1039 Added tests to check 8-bit/sample and double/sample combines work
1040 similarly.

1078
1079 - handling of the left-over bit for 16-bit/pixel TGA images has been
1080 changed to match the behaviour of the GIMP. Previously the bit
1081 being set was treated as an opaque pixel, but one user reported a
1082 problem with loading such an image. I haven't been able to find any
1083 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1084 I'll match it's behaviour. See issue 114913 in the GIMP's
1085 bugzilla.

1095 - the old dynaload code used Mach API functions to load dynamic
1096 libraries on Mac OS X. These APIs have been deprecated in OS X
1097 10.5 and were causing some build problems.

1099 will need version 10.3 or later of OS X.

1331 - reworked library probing, we can now set more than one probe
1332 function for a library. Disabled the default (non-freetype-config)
1333 library probe and added an extra probe function that searches for
1334 both ft2build.h and whatever it includes, and adds -I as needed.
1335 Hopefully this will fix build problems like

1371Bug fixes:
1372
1373 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)

1403Imager 0.55 - 16 Dec 2006
1404===========
1405
1406This is primarily a bug fix release.
1407
1408Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1409
1410There is one new feature:
1411
1412 - the Win32 font driver now supports UTF8 (RT 22166)
1413 http://www.cpanforum.com/threads/3276
1414 http://rt.cpan.org/Ticket/Display.html?id=22166
1415
1416Several bugs were fixed:
1417
1418 - the string() method would not output the string "0"
1419 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1420
1421 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1422 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1423
1424 - the gif_disposal and gif_user_input tags weren't being read from
1425 the file correctly
1426 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1427
1428 - gif.c was failing to build under MSVC
1429 http://rt.cpan.org/Ticket/Display.html?id=23922
1430
1431 - in some cases strings passed to the string() method were treated as
1432 terminated by NUL (chr 0)
1433 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1434
1435 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1436 that's the default build name for zlib on Win32.
1437 http://rt.cpan.org/Ticket/Display.html?id=23064
1438
1439 - search $Config{incpath} for headers too, which we should have been
1440 doing all along.
1441
1442Win32 font driver fixes:
1443
1444 - the global descent value from bounding box was the wrong sign
1445 http://www.cpanforum.com/threads/3276
1446
1447 - if the first or last glyph overflowed the left or right side of the
1448 advance width they would be clipped
1449
1450
1451Imager 0.54 - 14 Sep 2006
1452===========
1453
1454This is primarily a feature release:
1455
1456 - a new qtype value 'mixing' has been added to the scale()
1457 method. This is faster than 'normal', slower than 'preview'. This
1458 is based on the method used by pnmscale, and seems to produce less
1459 blurry results than normal.
1460 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1461
1462 - the rubthrough() method can now render onto images with an alpha
1463 channel.
1464 http://rt.cpan.org/Ticket/Display.html?id=20678
1465
1466 - the read_multi() method now falls back to calling doing a single
1467 image read via the read() method and write_multi() will now fall
1468 back to calling write() if a single image is supplied. This means
1469 you can simply call the read_multi() or write_multi() functions
1470 without having to check if the type is formatted by that method.
1471 http://rt.cpan.org/Ticket/Display.html?id=19457
1472 http://rt.cpan.org/Ticket/Display.html?id=19458
1473
1474 - the GIF loop extension can now be written. If you don't have
1475 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1476 should upgrade.
1477 http://rt.cpan.org/Ticket/Display.html?id=21185
1478
1479 - getscanline() and setscanline() can now read/write palette index
1480 based data from/to the image for paletted images, by setting type to
1481 'index'.
1482 http://rt.cpan.org/Ticket/Display.html?id=20338
1483
1484 - we no longer hassle you to disable GIF support
1485 http://rt.cpan.org/Ticket/Display.html?id=20687
1486
1487 - minor documentation fixes
1488
1489
1490Imager 0.53 - 26 Jul 2006
1491===========
1492
1493This is a bugfix release.
1494
1495Some test code was left in a code path not covered by the test
1496suite. A test was added to cover this code path and the test code was
1497removed.

1501Imager 0.52 - 25 Jul 2006
1502===========
1503
1504This is primarily a feature release, but contains a fair few bug
1505fixes, new features:
1506
1507 - ability to read and write MS Windows ICO and CUR files
1508
1509 - you can now add file format plugins to support new file formats
1510
1511 - add POD coverage tests
1512
1513 - setcolors() and addcolors() now accept color names and so on
1514 instead of requiring Imager::Color objects.
1515 http://rt.cpan.org/Ticket/Display.html?id=20056
1516
1517 - flood_fill() can now fill to a specified border color instead of
1518 just to the area the same color as the seed.
1519 http://rt.cpan.org/Ticket/Display.html?id=19618
1520
1521
1522Bug fixes:
1523
1524 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1525 calculating the advance width.
1526 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1527
1528 - bounding_box for the T1 driver wasn't including leading and
1529 trailing spaces in the bounding box as the other drivers did, it also
1530 produced strange results for empty strings or strings containing only
1531 spaces
1532
1533 - when reading CMYK jpeg images they were being transferred to the
1534 image object as is, producing a four channel image. It only looked ok
1535 due to an old still unfixed Photoshop bug. We now convert from the
1536 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1537 http://rt.cpan.org/Ticket/Display.html?id=20416
1538
1539 - reading a CYMK TIFF would result in a 4 channel image, reading any
1540 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1541 result in an error.
1542 http://rt.cpan.org/Ticket/Display.html?id=20415
1543
1544 - added /usr/local/include to the default include search path, since
1545 we were already searching /usr/local/lib for libraries.
1546
1547And various minor fixes and documentation updates.
1548
1549

1554 a crash
1555 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1556
1557 - fix mis-processing of the src_maxx and src_maxy parameters of the
1558 paste() method
1559 http://rt.cpan.org/Public/Bug/Display.html?id=18712

1571 output is an in-memeory buffer.

1573
1574 - fixes an incorrect pointer parameter in the PNG code
