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.

15Bug fixes:
16
93eab01e
TC
17 - getpixel(..., type => "float") and the API i_gpixf() have been
18 broken on paletted images since they were implemented.

TC
23 - links in the METHOD INDEX now point at the method documentation
24 rather than the heading you can find them under.

TC
27 - Imager (and the bundled dynamic modules) no longer fallback to
28 using DynaLoader if loading via XSLoader fails.
29 For the bundled modules this could hide useful error messages.
30 https://rt.cpan.org/Ticket/Display.html?id=75560
31
335078fc
TC
32 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a
33 buffer in the array of allocations, but just stores the filename
34 pointer and line number.

37Imager 0.88 - 22 Feb 2012
38===========
39
43bef43b
TC
40 - describe how to build libgif etc on OS X in such a way as to be
41 compatible with a fat binary perl (such as the system perl), in
42 README.
43 https://rt.cpan.org/Ticket/Display.html?id=73371
44
69675eef
TC
45 - update the change notes for 0.77_01 to indicate that libungif
46 support was removed.
47

TC
48 - add some other imaging modules to SEE ALSO
49 https://rt.cpan.org/Ticket/Display.html?id=73906
50
3b7f10da
TC
51 - note that the generator of the apparently non-DFSG-free postscript
52 in MMOne.pfb is a Debian package.
53
02323e69
TC
54 - setsamples() is now a true complement to getsamples() - it can
55 write 8-bit or floating point samples from a scalar or array
56 reference. This adds i_psamp() and i_psampf() to the C level API.
57
58 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
59 changed to make better use of the typemap, but these aren't part of
60 the perl level API anyway. There were no changes to the C level
61 interfaces to these functions.
62
2a27eeff
TC
63 - getpixel() and setpixel() now accept a mix of scalar and array
64 references for the x and y parameters, and unequal array lengths is
65 no longer an error.

74 rotate().
75 https://rt.cpan.org/Ticket/Display.html?id=69261
76
5091168a
TC
77 - Win32 text output is now done in normal combine mode, the alpha
78 component of the color is now significant.

80
fa0b1452
TC
81 - remove long unused gif case from read()
82 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
83
7640e3bb
TC
84 - the getsamples() target parameter was being treated as a hashref
85 when it's meant to be an array reference.
86 https://rt.cpan.org/Ticket/Display.html?id=74882
87
2a27eeff
TC
88 - getpixel() and setpixel() now returns an empty list when invalid
89 parameters are supplied.
90 Invalid values for type now result in an error for getpixel().

109 - make the error message from read() or read_multi() when they can't
110 identify the file type match reality.
111 https://rt.cpan.org/Ticket/Display.html?id=72475
112
113 - read() now uses $FORMATGUESS if it can't determine the file type
114 based on the file header, to match read_multi().
115
116 - re-work and add tests for def_guess_type(). def_guess_type() no
117 longer returns any random file extension as the file type.

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

TC
163 - add extra ppport.h configuration to support older perls.
164
954ac5d1
TC
165 - depend on Scalar::Util, since we use it and older perls don't have
166 it.
167
5efba0c6
TC
168 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
169 to synthesize it from overloaded "".
170
73e3ff55
TC
171 - use T1_StrError() for error messages on modern libt1
172 https://rt.cpan.org/Ticket/Display.html?id=69879
173
174 - actually load the font rather than just adding it to the catalog on
175 creation.
176
177 - Imager::Font->new now produces better error messages for the T1
178 engine.
179
6e938c74
TC
180 - the font has_chars() method now returns perl's true and false
181 values in list context rather than integers, which should be more
182 efficient.
183 https://rt.cpan.org/Ticket/Display.html?id=69158
184
b934971a
TC
185 - the btm data structure used by the flood_fill code is now

196 perl could order it differently.
197 https://rt.cpan.org/Ticket/Display.html?id=71675
198
336ce474
TC
199 - we rely on Config.pm's d_vsnprintf as to whether we use
200 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
201 though it only has _ prefixed versions of these. Define our own
202 prefixed names on Win32.

31be6e9a 211Imager 0.85_01 - 10 Oct 2011
6d5c85a2 212==============
a7e32beb
TC
213
214 - add simple tests for the Imager::Test test_image generators
215
6d5c85a2
TC
216 - io_glue I/O buffering re-work:
217
218 - reorganize io_glue to do it's own buffering by default
219
220 - the unbuffered functions are available as i_io_raw_read() (or
221 raw_read() from perl) etc but are not recommended for typical
222 use.
223
224 - use the new i_io_peekn() when checking for file magic to avoid
225 seek, allowing Imager to detect the file type and read the file
226 from an unseekable stream (for formats that don't use random
227 access)
228
229 - added several new I/O layer API functions.
230
231 - fix the TGA performance problem, most noticably on Win32
232 https://rt.cpan.org/Ticket/Display.html?id=70037
233
234 - TIFF now uses wrapper functions of the correct types to avoid casts
235 https://rt.cpan.org/Ticket/Display.html?id=69912
236
237 - the callback IO object did its own buffering, controlled by the
238 maxbuffer parameter supplied to the read() and write() methods.
239 This buffering has been removed, to avoid redundancy with the
240 common io_glue buffering. This also avoids a bug in that code
241 which could rarely pass a zero length to the read callback and
242 then panic about the result.
243
244 - the callback IO object now tests the result of calling the close
245 callback, which should return true for success.
246
247 - the PNM reader did its own buffering. This buffering has been
248 removed to avoid redundancy with the common io_glue buffering.
249
250 - previously the read handlers for fd and callback I/O layers would
251 call the underlying interface (POSIX read or your supplied callback)
252 until it filled the buffer. It now only makes one call.
253
254 - added public constructors for I/O layer objects (see Imager::IO)
255
256 - all core file handlers now use the i_io_foo() wrappers to gain
257 access to buffered I/O rather than calling the I/O layer
258 callbacks directly.
259
260 - all core file handlers now check for error on close.
261
262 - Backward compatibility: if you hava custom file handlers, you can
263 use i_io_write() etc since they're available as macros in older
264 versions of Imager.
265
266 - eliminate the final remnants of io_glue_commit_types().
267
268 - bump IMAGER_API_VERSION, since the above may break assumptions.
269
270 - removed the long unused i_gen_reader() and i_gen_writer() utility
271 functions.

6ad7e4bc
TC
274===========
275
0c647c9a
TC
276The main changes in the release versus 0.84 are:
277
278 - on 64-bit systems, 64-bit types are consistently used for image
279 dimensions and co-ordinated, and for memory block sizes.
280
281 - handle IFD loops in TIFF files correctly. Previously this would
282 lead to an infinite loop.
283
6ad7e4bc
TC
284Bug fixes:
285
286 - fix the link in the getheight() entry in the method index

292favourable.
6b7197d0
TC
293
294Bug fixes:
295
296 - the image file limits set by set_file_limits() weren't being
297 checked when reading TIFF files.
298 https://rt.cpan.org/Ticket/Display.html?id=69915
299
5970bd39
TC
300 - Provide more information about file format module load errors on a
301 failed image file read() or write().
302 https://rt.cpan.org/Ticket/Display.html?id=69194
303
4ce3551c
TC
304 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
305 through TIFF images, since it checks for IFD loops.
306 https://rt.cpan.org/Ticket/Display.html?id=69914
307
a16bca6d
TC
308 - don't leak memory when out of range palette indexes are supplied to
309 setscanline().
310 https://rt.cpan.org/Ticket/Display.html?id=69242
311
312 - require a later version of CPAN::Meta to ensure JSON::PP and
313 CPAN::Meta::YAML are available.
314 https://rt.cpan.org/Ticket/Display.html?id=69008
315
ac575c5f
TC
316 - hoist the per-line calculations for the flines implementations, and
317 modernize the tests a bit.
318 https://rt.cpan.org/Ticket/Display.html?id=70126
319
86c8d19a
TC
320 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
321 them when available.

323
a3fd7df7

331Imager 0.84_01 - 8 Aug 2011
332==============
333
334Development release as a sanity check for the types re-work.
8d14daab
TC
335
336Massive types re-work:
337
338 - the type used internally for pixel co-ordinates and image sizes is
339 now 64-bit on 64-bit platforms (at least sane ones).
340
341 - size_t is now used consistently for memory block sizes.
342
343 - since this changes the binary interface, the Imager API version has
344 been incremented. Any module that uses the API will need to be
345 rebuilt. In most cases that will be enough, but calls to any APIs
346 that take a pointer to image sizes may need source changes.
347
348 - you should be able to create very large images on 64-bit systems,
349 if you have enough memory. Successfully created a 32768 x 49192 x
350 3 channel image, filled with a tiled image and scaled it. The
351 unscaled image was also successfully saved to a JPEG.
352
353 - check the image size before attempting to write BMP, GIF, JPEG,
354 PNG, SGI, TGA, TIFF images.
355
356 - correctly handle reading TGA images over 32767 pixels wide or tall.
357
358Incidental changes:
359
360 - the gif_left and gif_top tags are now clamped to non-negative
361 values when writing a GIF image.
362
363 - removed dead callback read/write code
364
365The default maximum memory size when reading files is now 1G.

393 contains only grays when performing error diffusion color
394 translation.
395 https://rt.cpan.org/Ticket/Display.html?id=68508
396
59c150a4
TC
397 - writing a paletted image to GIF wouldn't always use the colors
398 supplied (or generated, eg. via make_colors => "mono"), which was
399 confusing at best.
400 https://rt.cpan.org/Ticket/Display.html?id=67912

426 - compose() with the target, source or mask position off the top or
427 left of the target image didn't clip the source image correctly.

429
430 - compose() now returns a useful error message on a non-positive
431 opacity.

TC
437===========
438
439Bug fixes:
440
441 - eliminate calls to i_has_format() from the test suite, since it's
442 no longer a useful way to check for file format support. Eliminate
443 i_has_format() from the functions exposed via XS.

445
7540f84a
TC
446 - eliminate calls to note(), which isn't in the (very old) version of
447 Test::More we have as a pre-requisite. note() is modern enough
448 that I don't feel a need to require a Test::More upgrade for it.

985 - i_scale_axis() wasn't checking the result of i_img_new_ch()
986 resulting in a SIGSEGV when attempting to scale an image to a size
987 too large to fit in memory. This is a NULL pointer access issue,

1003This release primarily contains changes to improve ease of use -
1004rather than you having to convert images to the appropriate number of
1005channels, Imager handles it internally. How to handle drawing colors
1006and the default combine mode is a thornier problem left for some other
1007release.

TC
1012 - moved the imtoc.perl code into Imager::Preprocess
1013
1014 - paste() and rubthrough() now adapt the source image data to the
1015 destination, so you can now safely paste/rubthrough from greyscale
1016 images to color images or back, or from alpha channel images to
1017 noalpha channels or back.
1018 https://rt.cpan.org/Ticket/Display.html?id=30908
1019
1020 - rubthrough() now falls back to pasting when the source doesn't have
1021 an alpha channel. This effectively treats the source as having a
1022 max alpha channel, the right thing to do.
1023 http://rt.cpan.org/Ticket/Display.html?id=29944
1024
1025 - re-worked most of the area filling code to use a common set of
1026 functions when filling.
1027 Corrected normal combine mode.
1028 Rewrote most of the combine modes to match the way the SVG draft
1029 defines them with respect to a translucent source and destination.
1030 Added tests for translucent source and destination.
1031 Added tests to check 8-bit/sample and double/sample combines work
1032 similarly.

1071 - handling of the left-over bit for 16-bit/pixel TGA images has been
1072 changed to match the behaviour of the GIMP. Previously the bit
1073 being set was treated as an opaque pixel, but one user reported a
1074 problem with loading such an image. I haven't been able to find any
1075 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1076 I'll match it's behaviour. See issue 114913 in the GIMP's
1077 bugzilla.

1087 - the old dynaload code used Mach API functions to load dynamic
1088 libraries on Mac OS X. These APIs have been deprecated in OS X
1089 10.5 and were causing some build problems.

1091 will need version 10.3 or later of OS X.

1363Bug fixes:
1364
1365 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
1366 was returning an image object with an extra reference, this
1367 resulted in a memory leak.

1376 http://rt.cpan.org/Ticket/Display.html?id=8426
1377
1378 - previously, reading ASCII PBM files required spaces between samples,

1395Imager 0.55 - 16 Dec 2006
1396===========
1397
1398This is primarily a bug fix release.
1399
1400Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1401
1402There is one new feature:
1403
1404 - the Win32 font driver now supports UTF8 (RT 22166)
1405 http://www.cpanforum.com/threads/3276
1406 http://rt.cpan.org/Ticket/Display.html?id=22166
1407
1408Several bugs were fixed:
1409
1410 - the string() method would not output the string "0"
1411 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1412
1413 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1414 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1415
1416 - the gif_disposal and gif_user_input tags weren't being read from
1417 the file correctly
1418 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1419
1420 - gif.c was failing to build under MSVC
1421 http://rt.cpan.org/Ticket/Display.html?id=23922
1422
1423 - in some cases strings passed to the string() method were treated as
1424 terminated by NUL (chr 0)
1425 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1426
1427 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1428 that's the default build name for zlib on Win32.
1429 http://rt.cpan.org/Ticket/Display.html?id=23064
1430
1431 - search $Config{incpath} for headers too, which we should have been
1432 doing all along.
1433
1434Win32 font driver fixes:
1435
1436 - the global descent value from bounding box was the wrong sign
1437 http://www.cpanforum.com/threads/3276
1438
1439 - if the first or last glyph overflowed the left or right side of the
1440 advance width they would be clipped
1441
1442
1443Imager 0.54 - 14 Sep 2006
1444===========
1445
1446This is primarily a feature release:
1447
1448 - a new qtype value 'mixing' has been added to the scale()
1449 method. This is faster than 'normal', slower than 'preview'. This
1450 is based on the method used by pnmscale, and seems to produce less
1451 blurry results than normal.
1452 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1453
1454 - the rubthrough() method can now render onto images with an alpha
1455 channel.
1456 http://rt.cpan.org/Ticket/Display.html?id=20678
1457
1458 - the read_multi() method now falls back to calling doing a single
1459 image read via the read() method and write_multi() will now fall
1460 back to calling write() if a single image is supplied. This means
1461 you can simply call the read_multi() or write_multi() functions
1462 without having to check if the type is formatted by that method.
1463 http://rt.cpan.org/Ticket/Display.html?id=19457
1464 http://rt.cpan.org/Ticket/Display.html?id=19458
1465
1466 - the GIF loop extension can now be written. If you don't have
1467 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1468 should upgrade.
1469 http://rt.cpan.org/Ticket/Display.html?id=21185
1470
1471 - getscanline() and setscanline() can now read/write palette index
1472 based data from/to the image for paletted images, by setting type to
1473 'index'.
1474 http://rt.cpan.org/Ticket/Display.html?id=20338
1475
1476 - we no longer hassle you to disable GIF support
1477 http://rt.cpan.org/Ticket/Display.html?id=20687
1478
1479 - minor documentation fixes
1480
1481
1482Imager 0.53 - 26 Jul 2006
1483===========
1484
1485This is a bugfix release.
1486
1487Some test code was left in a code path not covered by the test
1488suite. A test was added to cover this code path and the test code was
1489removed.
1490http://rt.cpan.org/Public/Bug/Display.html?id=20705
1491
1492
1493Imager 0.52 - 25 Jul 2006
1494===========
1495
1496This is primarily a feature release, but contains a fair few bug
1497fixes, new features:
1498
1499 - ability to read and write MS Windows ICO and CUR files
1500
1501 - you can now add file format plugins to support new file formats
1502
1503 - add POD coverage tests
1504
1505 - setcolors() and addcolors() now accept color names and so on
1506 instead of requiring Imager::Color objects.
1507 http://rt.cpan.org/Ticket/Display.html?id=20056
1508
1509 - flood_fill() can now fill to a specified border color instead of
1510 just to the area the same color as the seed.
1511 http://rt.cpan.org/Ticket/Display.html?id=19618
1512
1513
1514Bug fixes:
1515
1516 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1517 calculating the advance width.
1518 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1519
1520 - bounding_box for the T1 driver wasn't including leading and
1521 trailing spaces in the bounding box as the other drivers did, it also
1522 produced strange results for empty strings or strings containing only
1523 spaces
1524
1525 - when reading CMYK jpeg images they were being transferred to the
1526 image object as is, producing a four channel image. It only looked ok
1527 due to an old still unfixed Photoshop bug. We now convert from the
1528 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1529 http://rt.cpan.org/Ticket/Display.html?id=20416
1530
1531 - reading a CYMK TIFF would result in a 4 channel image, reading any
1532 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1533 result in an error.
1534 http://rt.cpan.org/Ticket/Display.html?id=20415
1535
1536 - added /usr/local/include to the default include search path, since
1537 we were already searching /usr/local/lib for libraries.
1538
1539And various minor fixes and documentation updates.
1540
1541
1542Imager 0.51 - 23 Apr 2006

1546 a crash
1547 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1548
1549 - fix mis-processing of the src_maxx and src_maxy parameters of the
1550 paste() method
1551 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1552
1553 - fix a problem in Imager's "smart" handling of the color parameter

1563 output is an in-memeory buffer.
1564 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1565
1566 - fixes an incorrect pointer parameter in the PNG code
1567 http://rt.cpan.org/Public/Bug/Display.html?id=18051
