3 - TIFF: handle SampleFormat = 2 by translating the signed integer
4 values to unsigned by flipping their sign bits.
5
6 Handle SampleFormat = 3 where possible.
7
8 SampleFormat is ignored for paletted images.
9
10 Mixed SampleFormat are be handled incorrectly, since libtiff
11 returns only the first SampleFormat value, and an image with both
12 an alpha channel and SampleFormat = 2 for color channels probably
13 has a different SampleFormat for the alpha channel.

20 - Imager::Color's rgba() method now returns it's values as integers
21 instead of floating point. (IV instead of NV).
22

TC
23 - The XS for i_map() and i_matrix_transform() now use the AV *
24 typemap instead of rolling their own.
25

TC
26 - The XS for DSO_call() now uses the HV * typemap instead of
27 rolling it's own.
28
0aaa8b4d
TC
29 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
30 i_gradgen() now use a new T_AVARRAY typemap that greatly
31 simplifies the XS code.

c2e251d9
TC
50 - rearrange Imager's test files.
51 https://rt.cpan.org/Ticket/Display.html?id=84596
52
53 - Imager::Probe::_gcc_lib_paths now forces C locale.
54 A sufficiently recent gcc prints localized keys for the search
55 paths, which avoids that localization.
56 https://rt.cpan.org/Ticket/Display.html?id=84963
57
58 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
59 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
60 and true.

67
68 - fix some spelling errors detected by the newer aspell in Debian
69 Wheezy.

77Imager 0.95 - 19 Apr 2013
78===========
79
0a2956ab
TC
80 - handle the SVf_UTF8 flag correctly on magic strings passed to
81 Imager::IO's write() and raw_write() methods.
82 This may misbehave in perl 5.6.x since the UTF8 flag may not be
83 visible in the main SV after SvGETMAGIC().
84 https://rt.cpan.org/Ticket/Display.html?id=83438
85
86 - document that bounding_box() ignores the transformation matrix
87 supplied to tranform() for fonts.

TC
90Imager 0.94_02 - 5 Apr 2013
91==============
92
1540d1d4
TC
93 - enable debug logging for the standard font tests
94
95 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
96 due to a bug in that version of perl.
97
98 - don't test for read() failing on a write-only handle in 5.8.x and
99 earlier, this was fixed in change 862083f7e4 in perl.
100
101 - report the version of Inline found during testing (an attempt to
102 diagnose some intermittent failures.)

TC
104Imager 0.94_01 - 2 Mar 2013
105==============
106
14a4ea18 107 - NOTE: possibly backward incompatible:
3dcf7595
TC
108 support reading from/writing to perl filehandes that aren't raw
109 files.
110
111 This allows Imager's I/O to honour handles with layers such as
112 gzip, scalar file handles or tied file handles.
113
14a4ea18 114 This is backward incompatible in that previous Imager would simply
3dcf7595
TC
115 use fileno() to retrieve the fd for the file and call write(2) etc
116 on it directly.
04d8c568
TC
117 https://rt.cpan.org/Ticket/Display.html?id=78843
118
119 - moved most of README to lib/Imager/Install.pod which should make it
120 more accessible to the "web" generation, also significantly updated
121 and re-worked it.
3dcf7595 122
ca96f811
TC
123 - updated README's for the separately distributed modules to refer to
124 Imager::Install, and that they need -dev versions of packages

TC
139 - drawing text to a channel with FT2 would draw with random coverage
140 due to an uninitialized alpha channel.
141
142 - marked the function pointer underlying the mm_log() API with the
143 correct gcc magic and fixed the resulting warnings.
144
145 - fixed some other compiler warnings
146
14a4ea18
TC
147 - Imager::Font::W32 now properly reports text drawing errors
148 https://rt.cpan.org/Ticket/Display.html?id=70098

14a4ea18
TC
151 strings passed as text to draw(), bounding_box(), has_chars(),
152 glyph_names() (where supported) in each of the font drivers.
0a2956ab
TC
153 This may misbehave in perl 5.6.x since the UTF8 flag may not be
154 visible in the main SV after SvGETMAGIC().

160Variations on some of these changes were included in development
161releases.
162
4be61824
TC
163 - improved thread safety
164 - the internal error stack and log file handle are now in a per-thread
165 context object
166 - JPEG now captures IPTC information in a thread-safe way
167 - avoid globals where possible for warning capture in libtiff
244725cf
TC
168 - use a mutex to avoid re-entering thread-unsafe giflib
169 - use a mutex to avoid re-entering thread-unsafe tifflib
170 - use a mutex to avoid re-entering thread-unsafe T1Lib
171 - use a library handle per thread for freetype 2.

187Imager 0.93 - 15 Oct 2012
188===========
189
190Bug fixes:
71fbe41a
TC
191
192 - previously a transparency enabled GIF write (the default) would
193 always use a GIF89a header even if none of the images were
194 transparent.
7a5f7bc6 195
b2f967ef
TC
196 - previously the probe step for freetype-config would fail on cygwin
197
b2f967ef
TC
198 - catch an invalid matrix parameter to convert() instead of crashing
199 https://rt.cpan.org/Ticket/Display.html?id=79922
200
201 - remove the 16-bit/sample limitation from the documentation for
202 setsamples(), it hasn't applied for many releases.
203 https://rt.cpan.org/Ticket/Display.html?id=79989
204
9673d97e

TC
215Enhancements:
216
217 - support for giflib 5.0. (5.0.1 and later)
218 https://rt.cpan.org/Ticket/Display.html?id=79029
219 The giflib API Imager uses doesn't have a mechanism to set the
220 header version in 5.0.0.
221
222 - update the GIF library probe code to check for the new giflib 5.0.1
223 EGifSetGifVersion() function, and to check for the giflib 4.2.0
224 uninitialized gif89 bug.
225 https://rt.cpan.org/Ticket/Display.html?id=79679
226 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
227
228 - avoid static variables when capturing IPTC data from JPEG files
229
230 - match Imager::Font;:T1's error message translations to those from
231 later versions of T1Lib.
232
233 - for libtiff versions that support extended warning handlers (3.8.0
234 or later), use them to avoid some global variables.
235
236 - note Image::ExifTool for better metadata support.

239Imager 0.92 - 14 Aug 2012
240===========
241
b1c75496
TC
242 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
243 correctly for both probing and runtime.
244 https://rt.cpan.org/Ticket/Display.html?id=77672
245
dcc10c4e

252
ef84bb32 253Bug fixes:
38742a13 254
289d65f4
TC
255 - The size of rotated images is no longer rounded up so aggressively.
256 Added rounding to the linear interpolation done for rotate() and
257 matrix_transform() for 1 and 3 channel 8-bit images.
258 Adjusted the two tranlate matrices used to build the final rotation
259 matrix to use the distance between the outlier pixels rather than
260 the pixel dimensions (ie. dimension-1).
261 With all of this the output of rotate(degrees => 270) on an 8-bit
262 image exactly matches the output of rotate(right => 270).
263 https://rt.cpan.org/Ticket/Display.html?id=77063
264
ef84bb32
TC
265Other changes:
266
267 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
268 internals, those names only matter for the XS interface.
269
270 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
271 the API level compiled into a loadable module such as
272 Imager::File::GIF doesn't match that of Imager. Previously it
273 could be difficult to determine exactly which module was failing to
274 load.
275 https://rt.cpan.org/Ticket/Display.html?id=77173
276
277 - added Imager->check_file_limits() as an interface to the
278 i_int_check_image_file_limits() API.
279
280 - Imager->set_file_limits(reset => 1) now resets the limits to the
281 defaults rather than setting them all to unlimited.
282
283 - wrote a brief security note as Imager::Security
284 https://rt.cpan.org/Ticket/Display.html?id=68910
285
6f31dd14 286Imager 0.90 - 30 Apr 2012
7c4464f5
TC
287===========
288
289Bug fixes:
290
291 - Imager::Test::is_imaged() attempted to process an "epsilon"
292 parameter but the prototype didn't allow for the extra parameter.
293 Corrected the prototype.
294
29b38678
TC
295 - when downconverting samples (eg. from floating point to 8 bit)
296 Imager now rounds the sample value rather than attempting to
297 allocate input values over output values equally. The old
298 behaviour had the probably surprising effect of converting a
299 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
300 2.
301 This may result in slightly different 8 or 16-bit output images.
302
e2a86bac
TC
303 - BI_BITFIELD BMP images were handled incorrectly, both in
304 incorrectly calculating the space required for the masks and in
305 processing the image data itself.
306 https://rt.cpan.org/Ticket/Display.html?id=76736
307
308 - some odd width BMP BI_RLE4 images use run lengths that run one off
309 the edge of the image. Imager now allows this, discarding the
310 extra column.
311
312 - odd length RLE4 runs in BMP images were decoded incorrectly.
313
82eb0687
TC
314 - pkg-config could sometimes return a library that was in a directory
315 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
316 If no -L is included in the pkg-config library information check if
317 EU::MM can find the library, and if not, search our configured
318 directories and insert that into the library flags.
319 https://rt.cpan.org/Ticket/Display.html?id=75869
320
de50f459
TC
321 - Imager::Probe can now probe for libraries with dependent libraries,
322 common for static linking, eg. libpng requires libz.
323 https://rt.cpan.org/Ticket/Display.html?id=74043
324
325 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
326
327 - added alternative probe configurations that try to link libz, to
328 handle a statically linked libpng.
329 https://rt.cpan.org/Ticket/Display.html?id=74043
330
331 - if a probe includes testcode, Imager::Probe now checks that code as
332 part of the process of checking each configuration rather than as a
333 post test of the found configuration. This allows alternate
334 configurations to be checked if a matching but non-working
335 configuration is found.
336 https://rt.cpan.org/Ticket/Display.html?id=74043
337
9d5ff8a6
TC
338Other changes:
339
340 - when reading or writing images via callbacks, the default callbacks
341 now push an error message indicating that a required callback was
342 called but not supplied.
343 https://rt.cpan.org/Ticket/Display.html?id=76782
344
345 - clarify which callbacks are required for reading and writing TIFF
346 images.
347
348 - improve logging for creation of callback I/O layers.
349
de50f459
TC
350 - a little more documentation for Imager::Probe.
351
594f5933
TC
352 - the i_get_file_background() and i_get_file_backgroundf() APIs now
353 return int to indicate whether the i_background tag was found.
354
1b46057d
TC
355 - PNG rework
356 - improve error reporting
357 - add png_interlace, png_bits tags
358 - read paletted images as paletted images, including transparency
359 - read 1 bit greyscale images as a type suitable for other file
360 handlers to write as bilevel
361 - read 16 bit/sample PNG as 16-bit/sample Imager images
362 - write "bilevel" paletted images as 1 bit grayscale images
363 - write paletted images as paletted images
364 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
365 images
366 - improved metadata support

383
a5919365
TC
384 - Imager (and the bundled dynamic modules) no longer fallback to
385 using DynaLoader if loading via XSLoader fails.
386 For the bundled modules this could hide useful error messages.
387 https://rt.cpan.org/Ticket/Display.html?id=75560
388

TC
389 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a

408 - note that the generator of the apparently non-DFSG-free postscript
409 in MMOne.pfb is a Debian package.
410
02323e69
TC
411 - setsamples() is now a true complement to getsamples() - it can
412 write 8-bit or floating point samples from a scalar or array
413 reference. This adds i_psamp() and i_psampf() to the C level API.
414
415 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
416 changed to make better use of the typemap, but these aren't part of
417 the perl level API anyway. There were no changes to the C level
418 interfaces to these functions.
419

TC
420 - getpixel() and setpixel() now accept a mix of scalar and array
421 references for the x and y parameters, and unequal array lengths is
422 no longer an error.

573 - io_glue I/O buffering re-work:
574
575 - reorganize io_glue to do it's own buffering by default
576
577 - the unbuffered functions are available as i_io_raw_read() (or
578 raw_read() from perl) etc but are not recommended for typical
579 use.
580
581 - use the new i_io_peekn() when checking for file magic to avoid
582 seek, allowing Imager to detect the file type and read the file
583 from an unseekable stream (for formats that don't use random
584 access)
585
586 - added several new I/O layer API functions.
587
588 - fix the TGA performance problem, most noticably on Win32
589 https://rt.cpan.org/Ticket/Display.html?id=70037
590
591 - TIFF now uses wrapper functions of the correct types to avoid casts
592 https://rt.cpan.org/Ticket/Display.html?id=69912
593
594 - the callback IO object did its own buffering, controlled by the
595 maxbuffer parameter supplied to the read() and write() methods.
596 This buffering has been removed, to avoid redundancy with the
597 common io_glue buffering. This also avoids a bug in that code
598 which could rarely pass a zero length to the read callback and
599 then panic about the result.
600
601 - the callback IO object now tests the result of calling the close
602 callback, which should return true for success.
603
604 - the PNM reader did its own buffering. This buffering has been
605 removed to avoid redundancy with the common io_glue buffering.
606
607 - previously the read handlers for fd and callback I/O layers would
608 call the underlying interface (POSIX read or your supplied callback)
609 until it filled the buffer. It now only makes one call.
610
611 - added public constructors for I/O layer objects (see Imager::IO)
612
613 - all core file handlers now use the i_io_foo() wrappers to gain
614 access to buffered I/O rather than calling the I/O layer
615 callbacks directly.
616
617 - all core file handlers now check for error on close.
618
619 - Backward compatibility: if you hava custom file handlers, you can
620 use i_io_write() etc since they're available as macros in older
621 versions of Imager.
622
623 - eliminate the final remnants of io_glue_commit_types().
624
625 - bump IMAGER_API_VERSION, since the above may break assumptions.
626
627 - removed the long unused i_gen_reader() and i_gen_writer() utility
628 functions.

691Development release as a sanity check for the types re-work.
8d14daab
TC
692
693Massive types re-work:
694
695 - the type used internally for pixel co-ordinates and image sizes is
696 now 64-bit on 64-bit platforms (at least sane ones).
697
698 - size_t is now used consistently for memory block sizes.
699
700 - since this changes the binary interface, the Imager API version has
701 been incremented. Any module that uses the API will need to be
702 rebuilt. In most cases that will be enough, but calls to any APIs
703 that take a pointer to image sizes may need source changes.
704
705 - you should be able to create very large images on 64-bit systems,
706 if you have enough memory. Successfully created a 32768 x 49192 x
707 3 channel image, filled with a tiled image and scaled it. The
708 unscaled image was also successfully saved to a JPEG.
709
710 - check the image size before attempting to write BMP, GIF, JPEG,
711 PNG, SGI, TGA, TIFF images.
712
713 - correctly handle reading TGA images over 32767 pixels wide or tall.
714
715Incidental changes:
716
717 - the gif_left and gif_top tags are now clamped to non-negative
718 values when writing a GIF image.
719
720 - removed dead callback read/write code
721
722The default maximum memory size when reading files is now 1G.

1360This release primarily contains changes to improve ease of use -
1361rather than you having to convert images to the appropriate number of
1362channels, Imager handles it internally. How to handle drawing colors
1363and the default combine mode is a thornier problem left for some other
1364release.

TC
1369 - moved the imtoc.perl code into Imager::Preprocess
1370
1371 - paste() and rubthrough() now adapt the source image data to the
1372 destination, so you can now safely paste/rubthrough from greyscale
1373 images to color images or back, or from alpha channel images to
1374 noalpha channels or back.
1375 https://rt.cpan.org/Ticket/Display.html?id=30908
1376
1377 - rubthrough() now falls back to pasting when the source doesn't have
1378 an alpha channel. This effectively treats the source as having a
1379 max alpha channel, the right thing to do.
1380 http://rt.cpan.org/Ticket/Display.html?id=29944
1381
1382 - re-worked most of the area filling code to use a common set of
1383 functions when filling.
1384 Corrected normal combine mode.
1385 Rewrote most of the combine modes to match the way the SVG draft
1386 defines them with respect to a translucent source and destination.
1387 Added tests for translucent source and destination.
1388 Added tests to check 8-bit/sample and double/sample combines work
1389 similarly.

1425 - some TGA images weren't being detected correctly as TGA images
1426 https://rt.cpan.org/Ticket/Display.html?id=32925
1427
1428 - handling of the left-over bit for 16-bit/pixel TGA images has been
1429 changed to match the behaviour of the GIMP. Previously the bit
1430 being set was treated as an opaque pixel, but one user reported a
1431 problem with loading such an image. I haven't been able to find any
1432 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1433 I'll match it's behaviour. See issue 114913 in the GIMP's
1434 bugzilla.

1444 - the old dynaload code used Mach API functions to load dynamic
1445 libraries on Mac OS X. These APIs have been deprecated in OS X
1446 10.5 and were causing some build problems.

1448 will need version 10.3 or later of OS X.

1760
1761 - the Win32 font driver now supports UTF8 (RT 22166)
1762 http://www.cpanforum.com/threads/3276
1763 http://rt.cpan.org/Ticket/Display.html?id=22166
1764
1765Several bugs were fixed:
1766
1767 - the string() method would not output the string "0"
1768 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1769
1770 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1771 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1772
1773 - the gif_disposal and gif_user_input tags weren't being read from
1774 the file correctly
1775 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1776
1777 - gif.c was failing to build under MSVC
1778 http://rt.cpan.org/Ticket/Display.html?id=23922
1779
1780 - in some cases strings passed to the string() method were treated as
1781 terminated by NUL (chr 0)
1782 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1783
1784 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1785 that's the default build name for zlib on Win32.
1786 http://rt.cpan.org/Ticket/Display.html?id=23064
1787
1788 - search $Config{incpath} for headers too, which we should have been
1789 doing all along.
1790
1791Win32 font driver fixes:
1792
1793 - the global descent value from bounding box was the wrong sign
1794 http://www.cpanforum.com/threads/3276
1795
1796 - if the first or last glyph overflowed the left or right side of the
1797 advance width they would be clipped
1798
1799
1800Imager 0.54 - 14 Sep 2006
1801===========
1802
1803This is primarily a feature release:
1804
1805 - a new qtype value 'mixing' has been added to the scale()
1806 method. This is faster than 'normal', slower than 'preview'. This
1807 is based on the method used by pnmscale, and seems to produce less
1808 blurry results than normal.
1809 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1810
1811 - the rubthrough() method can now render onto images with an alpha
1812 channel.
1813 http://rt.cpan.org/Ticket/Display.html?id=20678
1814
1815 - the read_multi() method now falls back to calling doing a single
1816 image read via the read() method and write_multi() will now fall
1817 back to calling write() if a single image is supplied. This means
1818 you can simply call the read_multi() or write_multi() functions
1819 without having to check if the type is formatted by that method.
1820 http://rt.cpan.org/Ticket/Display.html?id=19457
1821 http://rt.cpan.org/Ticket/Display.html?id=19458
1822
1823 - the GIF loop extension can now be written. If you don't have
1824 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1825 should upgrade.
1826 http://rt.cpan.org/Ticket/Display.html?id=21185
1827
1828 - getscanline() and setscanline() can now read/write palette index
1829 based data from/to the image for paletted images, by setting type to
1830 'index'.
1831 http://rt.cpan.org/Ticket/Display.html?id=20338
1832
1833 - we no longer hassle you to disable GIF support
1834 http://rt.cpan.org/Ticket/Display.html?id=20687
1835
1836 - minor documentation fixes
1837
1838
1839Imager 0.53 - 26 Jul 2006
1840===========
1841
1842This is a bugfix release.
1843
1844Some test code was left in a code path not covered by the test
1845suite. A test was added to cover this code path and the test code was
1846removed.
1847http://rt.cpan.org/Public/Bug/Display.html?id=20705
1848
1849
1850Imager 0.52 - 25 Jul 2006
1851===========
1852
1853This is primarily a feature release, but contains a fair few bug
1854fixes, new features:
1855
1856 - ability to read and write MS Windows ICO and CUR files
1857
1858 - you can now add file format plugins to support new file formats
1859
1860 - add POD coverage tests
1861
1862 - setcolors() and addcolors() now accept color names and so on
1863 instead of requiring Imager::Color objects.
1864 http://rt.cpan.org/Ticket/Display.html?id=20056
1865
1866 - flood_fill() can now fill to a specified border color instead of
1867 just to the area the same color as the seed.
1868 http://rt.cpan.org/Ticket/Display.html?id=19618
1869
1870
1871Bug fixes:
1872
1873 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1874 calculating the advance width.
1875 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1876
1877 - bounding_box for the T1 driver wasn't including leading and
1878 trailing spaces in the bounding box as the other drivers did, it also
1879 produced strange results for empty strings or strings containing only
1880 spaces
1881
1882 - when reading CMYK jpeg images they were being transferred to the
1883 image object as is, producing a four channel image. It only looked ok
1884 due to an old still unfixed Photoshop bug. We now convert from the
1885 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1886 http://rt.cpan.org/Ticket/Display.html?id=20416
1887
1888 - reading a CYMK TIFF would result in a 4 channel image, reading any
1889 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1890 result in an error.
1891 http://rt.cpan.org/Ticket/Display.html?id=20415
1892
1893 - added /usr/local/include to the default include search path, since
1894 we were already searching /usr/local/lib for libraries.
1895
1896And various minor fixes and documentation updates.
1897
1898
