43bef43b
TC
6 - describe how to build libgif etc on OS X in such a way as to be
7 compatible with a fat binary perl (such as the system perl), in
8 README.
9 https://rt.cpan.org/Ticket/Display.html?id=73371
10
69675eef
TC
11 - update the change notes for 0.77_01 to indicate that libungif
12 support was removed.
13
d4056453
TC
14 - add some other imaging modules to SEE ALSO
15 https://rt.cpan.org/Ticket/Display.html?id=73906
16
3b7f10da
TC
17 - note that the generator of the apparently non-DFSG-free postscript
18 in MMOne.pfb is a Debian package.
19
02323e69
TC
20 - setsamples() is now a true complement to getsamples() - it can
21 write 8-bit or floating point samples from a scalar or array
22 reference. This adds i_psamp() and i_psampf() to the C level API.
23
24 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
25 changed to make better use of the typemap, but these aren't part of
26 the perl level API anyway. There were no changes to the C level
27 interfaces to these functions.
28
2a27eeff
TC
29 - getpixel() and setpixel() now accept a mix of scalar and array
30 references for the x and y parameters, and unequal array lengths is
31 no longer an error.
32 https://rt.cpan.org/Ticket/Display.html?id=73697
33

40 rotate().
41 https://rt.cpan.org/Ticket/Display.html?id=69261
42
5091168a
TC
43 - Win32 text output is now done in normal combine mode, the alpha
44 component of the color is now significant.
45 https://rt.cpan.org/Ticket/Display.html?id=70014
46
fa0b1452
TC
47 - remove long unused gif case from read()
48 https://rt.cpan.org/Ticket/Display.html?id=69244 (partial)
49
7640e3bb
TC
50 - the getsamples() target parameter was being treated as a hashref
51 when it's meant to be an array reference.
52 https://rt.cpan.org/Ticket/Display.html?id=74882
53
2a27eeff
TC
54 - getpixel() and setpixel() now returns an empty list when invalid
55 parameters are supplied.
56 Invalid values for type now result in an error for getpixel().

71
2fe1e4bc
TC
72 - correctly read and write 256x256 pixel ICO files
73 https://rt.cpan.org/Ticket/Display.html?id=69599
74
4f21e06e
TC
75 - make the error message from read() or read_multi() when they can't
76 identify the file type match reality.
77 https://rt.cpan.org/Ticket/Display.html?id=72475
78
79 - read() now uses $FORMATGUESS if it can't determine the file type
80 based on the file header, to match read_multi().
81
82 - re-work and add tests for def_guess_type(). def_guess_type() no
83 longer returns any random file extension as the file type.
84
5e9a7fbd
TC
85 - add gray4, gray16 and gray as presets for make_colors.
86 https://rt.cpan.org/Ticket/Display.html?id=67911

96 writing to a 1 or 3 channel image the second or fourth channel of
97 the source color was being ignored, it is now significant.

128
f35d1231
TC
129 - add extra ppport.h configuration to support older perls.
130
954ac5d1
TC
131 - depend on Scalar::Util, since we use it and older perls don't have
132 it.
133
5efba0c6
TC
134 - add overloaded eq to Imager::Matrix2d, since older perls don't seem
135 to synthesize it from overloaded "".
136
73e3ff55
TC
137 - use T1_StrError() for error messages on modern libt1
138 https://rt.cpan.org/Ticket/Display.html?id=69879
139
140 - actually load the font rather than just adding it to the catalog on
141 creation.
142
143 - Imager::Font->new now produces better error messages for the T1
144 engine.
145
6e938c74
TC
146 - the font has_chars() method now returns perl's true and false
147 values in list context rather than integers, which should be more
148 efficient.
149 https://rt.cpan.org/Ticket/Display.html?id=69158
150
b934971a
TC
151 - the btm data structure used by the flood_fill code is now

159 https://rt.cpan.org/Ticket/Display.html?id=68993
160
81409c5e
TC
161 - make the APIRef synopsis ordering consistent, older versions of
162 perl could order it differently.
163 https://rt.cpan.org/Ticket/Display.html?id=71675
164
336ce474
TC
165 - we rely on Config.pm's d_vsnprintf as to whether we use
166 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
167 though it only has _ prefixed versions of these. Define our own
168 prefixed names on Win32.
169 https://rt.cpan.org/Ticket/Display.html?id=71642
170
ae394c13
TC
171 - fix library detection with MSVC
172
84e2cc94

31be6e9a 177Imager 0.85_01 - 10 Oct 2011
6d5c85a2 178==============
a7e32beb
TC
179
180 - add simple tests for the Imager::Test test_image generators
181
6d5c85a2
TC
182 - io_glue I/O buffering re-work:
183
184 - reorganize io_glue to do it's own buffering by default
185
186 - the unbuffered functions are available as i_io_raw_read() (or
187 raw_read() from perl) etc but are not recommended for typical
188 use.
189
190 - use the new i_io_peekn() when checking for file magic to avoid
191 seek, allowing Imager to detect the file type and read the file
192 from an unseekable stream (for formats that don't use random
193 access)
194
195 - added several new I/O layer API functions.
196
197 - fix the TGA performance problem, most noticably on Win32
198 https://rt.cpan.org/Ticket/Display.html?id=70037
199
200 - TIFF now uses wrapper functions of the correct types to avoid casts
201 https://rt.cpan.org/Ticket/Display.html?id=69912
202
203 - the callback IO object did its own buffering, controlled by the
204 maxbuffer parameter supplied to the read() and write() methods.
205 This buffering has been removed, to avoid redundancy with the
206 common io_glue buffering. This also avoids a bug in that code
207 which could rarely pass a zero length to the read callback and
208 then panic about the result.
209
210 - the callback IO object now tests the result of calling the close
211 callback, which should return true for success.
212
213 - the PNM reader did its own buffering. This buffering has been
214 removed to avoid redundancy with the common io_glue buffering.
215
216 - previously the read handlers for fd and callback I/O layers would
217 call the underlying interface (POSIX read or your supplied callback)
218 until it filled the buffer. It now only makes one call.
219
220 - added public constructors for I/O layer objects (see Imager::IO)
221
222 - all core file handlers now use the i_io_foo() wrappers to gain
223 access to buffered I/O rather than calling the I/O layer
224 callbacks directly.
225
226 - all core file handlers now check for error on close.
227
228 - Backward compatibility: if you hava custom file handlers, you can
229 use i_io_write() etc since they're available as macros in older
230 versions of Imager.
231
232 - eliminate the final remnants of io_glue_commit_types().
233
234 - bump IMAGER_API_VERSION, since the above may break assumptions.
235
236 - removed the long unused i_gen_reader() and i_gen_writer() utility
237 functions.

6ad7e4bc
TC
240===========
241
0c647c9a
TC
242The main changes in the release versus 0.84 are:
243
244 - on 64-bit systems, 64-bit types are consistently used for image
245 dimensions and co-ordinated, and for memory block sizes.
246
247 - handle IFD loops in TIFF files correctly. Previously this would
248 lead to an infinite loop.
249
6ad7e4bc
TC
250Bug fixes:
251
252 - fix the link in the getheight() entry in the method index

258favourable.
6b7197d0
TC
259
260Bug fixes:
261
262 - the image file limits set by set_file_limits() weren't being
263 checked when reading TIFF files.
264 https://rt.cpan.org/Ticket/Display.html?id=69915
265
5970bd39
TC
266 - Provide more information about file format module load errors on a
267 failed image file read() or write().
268 https://rt.cpan.org/Ticket/Display.html?id=69194
269
4ce3551c
TC
270 - use TIFFReadDirectory() instead of TIFFSetDirectory() to iterate
271 through TIFF images, since it checks for IFD loops.
272 https://rt.cpan.org/Ticket/Display.html?id=69914
273
a16bca6d
TC
274 - don't leak memory when out of range palette indexes are supplied to
275 setscanline().
276 https://rt.cpan.org/Ticket/Display.html?id=69242
277
278 - require a later version of CPAN::Meta to ensure JSON::PP and
279 CPAN::Meta::YAML are available.
280 https://rt.cpan.org/Ticket/Display.html?id=69008
281
ac575c5f
TC
282 - hoist the per-line calculations for the flines implementations, and
283 modernize the tests a bit.
284 https://rt.cpan.org/Ticket/Display.html?id=70126
285
86c8d19a
TC
286 - detect snprintf()/vsnprintf() (cheat by using Config.pm) and use
287 them when available.
288 https://rt.cpan.org/Ticket/Display.html?id=69147
289
a3fd7df7
TC
290 - if t1lib failed to reinitialize it would be left as marked

297Imager 0.84_01 - 8 Aug 2011
298==============
299
300Development release as a sanity check for the types re-work.
8d14daab
TC
301
302Massive types re-work:
303
304 - the type used internally for pixel co-ordinates and image sizes is
305 now 64-bit on 64-bit platforms (at least sane ones).
306
307 - size_t is now used consistently for memory block sizes.
308
309 - since this changes the binary interface, the Imager API version has
310 been incremented. Any module that uses the API will need to be
311 rebuilt. In most cases that will be enough, but calls to any APIs
312 that take a pointer to image sizes may need source changes.
313
314 - you should be able to create very large images on 64-bit systems,
315 if you have enough memory. Successfully created a 32768 x 49192 x
316 3 channel image, filled with a tiled image and scaled it. The
317 unscaled image was also successfully saved to a JPEG.
318
319 - check the image size before attempting to write BMP, GIF, JPEG,
320 PNG, SGI, TGA, TIFF images.
321
322 - correctly handle reading TGA images over 32767 pixels wide or tall.
323
324Incidental changes:
325
326 - the gif_left and gif_top tags are now clamped to non-negative
327 values when writing a GIF image.
328
329 - removed dead callback read/write code
330
331The default maximum memory size when reading files is now 1G.

TC
334===========
335
336 - Imager no longer inherits from Exporter (unless you're running an
337 old, old perl.
338
92e9df65
TC
339 - Imager can now write progressive JPEGs (it could always read them).

341
10ea52a3
TC
342Bug fixes:

TC
358 - convert colors to grayscale if the supplied (or generated) palette
359 contains only grays when performing error diffusion color
360 translation.
361 https://rt.cpan.org/Ticket/Display.html?id=68508
362
59c150a4
TC
363 - writing a paletted image to GIF wouldn't always use the colors
364 supplied (or generated, eg. via make_colors => "mono"), which was
365 confusing at best.
366 https://rt.cpan.org/Ticket/Display.html?id=67912
367
5b480b14
TC
368 - replace (imager|tony)@imager.perl.org in the doc, since I don't

395
396 - compose() now returns a useful error message on a non-positive
397 opacity.
398
399 - compose.im now at 100% test coverage. (As opposed to, umm, much,
400 much less.)

TC
403===========
404
405Bug fixes:
406
407 - eliminate calls to i_has_format() from the test suite, since it's
408 no longer a useful way to check for file format support. Eliminate
409 i_has_format() from the functions exposed via XS.
410 https://rt.cpan.org/Ticket/Display.html?id=65863
411
7540f84a
TC
412 - eliminate calls to note(), which isn't in the (very old) version of
413 Test::More we have as a pre-requisite. note() is modern enough
414 that I don't feel a need to require a Test::More upgrade for it.
415 https://rt.cpan.org/Ticket/Display.html?id=65864

427 downgrade the version in this file.
428 https://rt.cpan.org/Ticket/Display.html?id=66250
429
430 - if we see an -rpath (or -R) option in $Config{lddlflags} supply
431 that option for the directories that would normally go in
432 LD_RUN_PATH. Typically an explicit -rpath overrides LD_RUN_PATH.

951 - i_scale_axis() wasn't checking the result of i_img_new_ch()
952 resulting in a SIGSEGV when attempting to scale an image to a size
953 too large to fit in memory. This is a NULL pointer access issue,
954 not a buffer overflow.

969This release primarily contains changes to improve ease of use -
970rather than you having to convert images to the appropriate number of
971channels, Imager handles it internally. How to handle drawing colors
972and the default combine mode is a thornier problem left for some other
973release.

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

980 - paste() and rubthrough() now adapt the source image data to the
981 destination, so you can now safely paste/rubthrough from greyscale
982 images to color images or back, or from alpha channel images to
983 noalpha channels or back.
984 https://rt.cpan.org/Ticket/Display.html?id=30908
985
986 - rubthrough() now falls back to pasting when the source doesn't have
987 an alpha channel. This effectively treats the source as having a
988 max alpha channel, the right thing to do.
989 http://rt.cpan.org/Ticket/Display.html?id=29944
990
991 - re-worked most of the area filling code to use a common set of
992 functions when filling.
993 Corrected normal combine mode.
994 Rewrote most of the combine modes to match the way the SVG draft
995 defines them with respect to a translucent source and destination.
996 Added tests for translucent source and destination.
997 Added tests to check 8-bit/sample and double/sample combines work
998 similarly.

1037 - handling of the left-over bit for 16-bit/pixel TGA images has been
1038 changed to match the behaviour of the GIMP. Previously the bit
1039 being set was treated as an opaque pixel, but one user reported a
1040 problem with loading such an image. I haven't been able to find any
1041 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1042 I'll match it's behaviour. See issue 114913 in the GIMP's
1043 bugzilla.

1053 - the old dynaload code used Mach API functions to load dynamic

1329Bug fixes:
1330
1331 - CRITICAL: the "Imager" typemap entry (not used by Imager itself)
1332 was returning an image object with an extra reference, this
1333 resulted in a memory leak.
1334 http://rt.cpan.org/Ticket/Display.html?id=24992
1335
1336 - fix rendering on alpha channel images for the FreeType 2.x driver
1337 http://rt.cpan.org/Ticket/Display.html?id=11972
1338
1339 - reading bmp files now consitently handles short reads. You can now
1340 supply a parameter to treat a short read as successful and set
1341 i_incomplete
1342 http://rt.cpan.org/Ticket/Display.html?id=8426
1343
1344 - previously, reading ASCII PBM files required spaces between samples,
1345 even though the format doesn't require that

1347 - improved documentation of the unsharpmask filter (I hope)
1348 http://rt.cpan.org/Ticket/Display.html?id=25531
1349
1350 - force flushing of the output from i_tt_dump_names() and test output
1351 in t/t35ttfont.t to prevent output from being mixed up.
1352 https://rt.cpan.org/Ticket/Display.html?id=24859
1353
1354 - rewrite a conditional expression as an if() to hopefully work around
1355 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.

1361Imager 0.55 - 16 Dec 2006
1362===========
1363
1364This is primarily a bug fix release.
1365
1366Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1367
1368There is one new feature:
1369
1370 - the Win32 font driver now supports UTF8 (RT 22166)
1371 http://www.cpanforum.com/threads/3276
1372 http://rt.cpan.org/Ticket/Display.html?id=22166
1373
1374Several bugs were fixed:
1375
1376 - the string() method would not output the string "0"
1377 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1378
1379 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1380 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1381
1382 - the gif_disposal and gif_user_input tags weren't being read from
1383 the file correctly
1384 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1385
1386 - gif.c was failing to build under MSVC
1387 http://rt.cpan.org/Ticket/Display.html?id=23922
1388
1389 - in some cases strings passed to the string() method were treated as
1390 terminated by NUL (chr 0)
1391 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1392
1393 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1394 that's the default build name for zlib on Win32.
1395 http://rt.cpan.org/Ticket/Display.html?id=23064
1396
1397 - search $Config{incpath} for headers too, which we should have been
1398 doing all along.
1399
1400Win32 font driver fixes:
1401
1402 - the global descent value from bounding box was the wrong sign
1403 http://www.cpanforum.com/threads/3276
1404
1405 - if the first or last glyph overflowed the left or right side of the
1406 advance width they would be clipped
1407
1408
1409Imager 0.54 - 14 Sep 2006
1410===========
1411
1412This is primarily a feature release:
1413
1414 - a new qtype value 'mixing' has been added to the scale()
1415 method. This is faster than 'normal', slower than 'preview'. This
1416 is based on the method used by pnmscale, and seems to produce less
1417 blurry results than normal.
1418 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1419
1420 - the rubthrough() method can now render onto images with an alpha
1421 channel.
1422 http://rt.cpan.org/Ticket/Display.html?id=20678
1423
1424 - the read_multi() method now falls back to calling doing a single
1425 image read via the read() method and write_multi() will now fall
1426 back to calling write() if a single image is supplied. This means
1427 you can simply call the read_multi() or write_multi() functions
1428 without having to check if the type is formatted by that method.
1429 http://rt.cpan.org/Ticket/Display.html?id=19457
1430 http://rt.cpan.org/Ticket/Display.html?id=19458
1431
1432 - the GIF loop extension can now be written. If you don't have
1433 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1434 should upgrade.
1435 http://rt.cpan.org/Ticket/Display.html?id=21185
1436
1437 - getscanline() and setscanline() can now read/write palette index
1438 based data from/to the image for paletted images, by setting type to
1439 'index'.
1440 http://rt.cpan.org/Ticket/Display.html?id=20338
1441
1442 - we no longer hassle you to disable GIF support
1443 http://rt.cpan.org/Ticket/Display.html?id=20687
1444
1445 - minor documentation fixes
1446
1447
1448Imager 0.53 - 26 Jul 2006
1449===========
1450
1451This is a bugfix release.
1452
1453Some test code was left in a code path not covered by the test
1454suite. A test was added to cover this code path and the test code was
1455removed.
1456http://rt.cpan.org/Public/Bug/Display.html?id=20705
1457
1458
1459Imager 0.52 - 25 Jul 2006
1460===========
1461
1462This is primarily a feature release, but contains a fair few bug
1463fixes, new features:
1464
1465 - ability to read and write MS Windows ICO and CUR files
1466
1467 - you can now add file format plugins to support new file formats
1468
1469 - add POD coverage tests
1470
1471 - setcolors() and addcolors() now accept color names and so on
1472 instead of requiring Imager::Color objects.
1473 http://rt.cpan.org/Ticket/Display.html?id=20056
1474
1475 - flood_fill() can now fill to a specified border color instead of
1476 just to the area the same color as the seed.
1477 http://rt.cpan.org/Ticket/Display.html?id=19618
1478
1479
1480Bug fixes:
1481
1482 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1483 calculating the advance width.
1484 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1485
1486 - bounding_box for the T1 driver wasn't including leading and
1487 trailing spaces in the bounding box as the other drivers did, it also
1488 produced strange results for empty strings or strings containing only
1489 spaces
1490
1491 - when reading CMYK jpeg images they were being transferred to the
1492 image object as is, producing a four channel image. It only looked ok
1493 due to an old still unfixed Photoshop bug. We now convert from the
1494 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1495 http://rt.cpan.org/Ticket/Display.html?id=20416
1496
1497 - reading a CYMK TIFF would result in a 4 channel image, reading any
1498 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1499 result in an error.
1500 http://rt.cpan.org/Ticket/Display.html?id=20415
1501
1502 - added /usr/local/include to the default include search path, since
1503 we were already searching /usr/local/lib for libraries.
1504
1505And various minor fixes and documentation updates.
1506
1507
1508Imager 0.51 - 23 Apr 2006

1512 a crash
1513 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1514
1515 - fix mis-processing of the src_maxx and src_maxy parameters of the
1516 paste() method
1517 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1518
1519 - fix a problem in Imager's "smart" handling of the color parameter
1520 to various methods.
1521 http://rt.cpan.org/Public/Bug/Display.html?id=18561
1522
1523

1528 or 4 channel image to jpeg or a 2 channel image to tga where the
1529 output is an in-memeory buffer.
1530 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1531
1532 - fixes an incorrect pointer parameter in the PNG code
1533 http://rt.cpan.org/Public/Bug/Display.html?id=18051
1534
1535 - skip Inline::C tests when building in a directory with spaces
1536 http://rt.cpan.org/Public/Bug/Display.html?id=18049
