55==============
56
5dab5b9a
TC
57 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
58 the blue channel in the generated palette, and allow each color
59 component to be in the range 100..255 instead of just 100..254.
60 Thanks to Ralf Neubauer.
61 https://rt.cpan.org/Ticket/Display.html?id=97086
62
63 - revert "improved the XS for i_io_read() and i_io_raw_read()"
64 This caused problems with older perls and didn't provide much of a
65 performance improvement.
66
5bf25bc2 67 - support Inline 0.57 and later.
6d47a6af 68 Inline 0.57 changed the "with" interface.

TC
71 - don't define our own MAXINT macro, it conflicts with windows header
72 files and in a few places it was the wrong value to use anyway.

TC
78 - GIF: add support for giflib 5.1.0, which added error code pointer
79 parameters to EGifCloseFile() and DGifCloseFile().
80 https://rt.cpan.org/Ticket/Display.html?id=96756
81
82 - GIF: avoid a double-free when do_write() fails.

91Imager 0.99 - 25 Jun 2014
92===========
93
dce1523b
TC
94 - Imager::IO->new_buffer() (and hence Imager->read()'s data
95 parameter) now accepts a reference to a scalar as well as just a
96 plain scalar.
6a160bce 97 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
98
99 - Imager::IO->new_buffer() now always makes a copy of the passed in
100 buffer to avoid problems with temporary objects used for the return
101 value of SvPVbyte().
6a160bce 102 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 103
c757e211
TC
104 - improved the XS for i_io_read() and i_io_raw_read()
105 https://rt.cpan.org/Ticket/Display.html?id=92738
106
107 - load plugins from absolute paths on Android
108 Thanks to Brian Fraser.
109 https://rt.cpan.org/Ticket/Display.html?id=93272
110
6a160bce
TC
111 - added the jpeg_optimize parameter for writing JPEG files. This can
112 significantly reduce file sizes, but uses more memory and time.
113 https://rt.cpan.org/Ticket/Display.html?id=94292
114
14fd9e5d
TC
115 - the autolevels filter now works on the luminosity of the image
116 rather then working per channel. The old autolevels filter is
117 still available as "autolevels_skew".
118 https://rt.cpan.org/Ticket/Display.html?id=94413
119
75d54149
TC
120 - Imager::File::PNG now supports libpng 1.6.10.
121 1.6.10 changed CRC errors from benign errors to normal errors,
122 which broke the test which used CRC errors to check for benign
123 error support. Switched to using a 1-bit grey-scale image with a
124 palette to test for benign errors.

127Imager 0.98 - 3 Jan 2014
128===========
129
f84f86a2
TC
130Incompatible changes:
131
132 - the return value of setpixel() has changed.
133
134 Previously the return values for undrawable pixels vs caller errors
135 changed depending on whether you used the multiple pixel calling
136 mechanism, or the single pixel mechanism.
137
138 Now:
139
140 - for an invalid parameter, such as an unknown colour, or missing
141 parameter, an empty list (or undef in scalar context) is
142 returned, and errstr() is set,
143
144 - otherwise the number of pixels drawn is returned. If none of
145 the pixels could be drawn (they were all outside the image), "0
146 but true" is returned.
147
148 https://rt.cpan.org/Ticket/Display.html?id=87650
149
150Other changes:
151
6ba09ab9
TC
152 - when drawing on an image with an alpha channel where the source
153 minimum is greater than zero, Imager would read from beyond the end
154 of a malloc() allocated buffer. In rare circumstances this could
155 lead to some of the source image not being written to the target
156 image, or possibly to a segmentation fault.
157 I don't believe this has any security concerns beyond that.
158
0d052fd9
TC
159 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
160 text drawn would be nonsense. This would also read beyond the end
161 of a malloced buffer.
162
13671b17
TC
163 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
164 truncated early.
165 https://rt.cpan.org/Ticket/Display.html?id=88993
166
d6f4e964
TC
167 - Imager::Font::Wrap no longer requires the image parameter.
168 https://rt.cpan.org/Ticket/Display.html?id=87338
169
f84f86a2
TC
170 - a documentation typo fix in Imager::Transformations
171 Thanks to Adrian Yee.
172 https://rt.cpan.org/Ticket/Display.html?id=88598
173
0179ecd6
TC
174 - Image::Probe, Imager's internal module for probing library
175 locations now searches the directories specified by LD_RUN_PATH,
176 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
177 and the corresponing s/\blib$/include/ directories for header
178 files.

186Imager 0.96_02 - 8 Jul 2013
187==============
188
aaf82685
TC
189 - PNG: treat a version mismatch between headers and library as a
190 probe failure.
191 https://rt.cpan.org/Ticket/Display.html?id=86659
192
8e90f677
TC
193 - PNG: the check for benign error support is more complex than a
194 simple library version check, check for the appropriate macro.
195 Thanks for Slaven Rezic for following up on my CPAN Testers result
196 queries.
197 https://rt.cpan.org/Ticket/Display.html?id=86659

203==============
204
05c9b356
TC
205 - TIFF: handle SampleFormat = 2 by translating the signed integer
206 values to unsigned by flipping their sign bits.
207
208 Handle SampleFormat = 3 where possible.
209
210 SampleFormat is ignored for paletted images.
211
237d9e03
TC
212 Mixed SampleFormat are handled incorrectly, since libtiff returns
213 only the first SampleFormat value, and an image with both an alpha
214 channel and SampleFormat = 2 for color channels probably has a
215 different SampleFormat for the alpha channel.

face45e7 219 - XS clean up:
29969fa2 220 https://rt.cpan.org/Ticket/Display.html?id=69243
face45e7 221
237d9e03 222 - Imager::Color's rgba() method now returns its values as integers
face45e7
TC
223 instead of floating point. (IV instead of NV).
224
19e9591b
TC
225 - The XS for i_map() and i_matrix_transform() now use the AV *
226 typemap instead of rolling their own.
227
75cebca8
TC
228 - The XS for DSO_call() now uses the HV * typemap instead of
229 rolling it's own.
230
0aaa8b4d
TC
231 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
232 i_gradgen() now use a new T_AVARRAY typemap that greatly
233 simplifies the XS code.
face45e7 234
ccd01d49
TC
235 - many other minor XS changes
236
face45e7 237 - some XS code formatting
a54e32ba 238
dcab59bc
TC
239 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
240 now renders in alpha-combining mode, to match antialiased output.
241 https://rt.cpan.org/Ticket/Display.html?id=73359
b482243a 242
8db7b6fa
TC
243 - add sample code and cookbook notes for drawing a blurred drop-shadow.
244
245 - add support for libpng 1.6, which changed the defaults for
246 reporting some types of error.

dc076f98
TC
249 - FT2: use gsamp/psamp() to transfer pixels from the work image to
250 the output image instead of gpix/ppix.

258
c2e251d9
TC
259 - rearrange Imager's test files.
260 https://rt.cpan.org/Ticket/Display.html?id=84596
261
262 - Imager::Probe::_gcc_lib_paths now forces C locale.
263 A sufficiently recent gcc prints localized keys for the search
264 paths, which avoids that localization.
265 https://rt.cpan.org/Ticket/Display.html?id=84963
266
267 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
268 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
269 and true.
270 https://rt.cpan.org/Ticket/Display.html?id=85262
271 reported by Andreas König

277 - fix some spelling errors detected by the newer aspell in Debian
278 Wheezy.

TC
286Imager 0.95 - 19 Apr 2013
287===========
288
0a2956ab
TC
289 - handle the SVf_UTF8 flag correctly on magic strings passed to
290 Imager::IO's write() and raw_write() methods.
291 This may misbehave in perl 5.6.x since the UTF8 flag may not be
292 visible in the main SV after SvGETMAGIC().
293 https://rt.cpan.org/Ticket/Display.html?id=83438
294
295 - document that bounding_box() ignores the transformation matrix
296 supplied to tranform() for fonts.

TC
302 - enable debug logging for the standard font tests
303
304 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
305 due to a bug in that version of perl.
306
307 - don't test for read() failing on a write-only handle in 5.8.x and
308 earlier, this was fixed in change 862083f7e4 in perl.
309
310 - report the version of Inline found during testing (an attempt to
311 diagnose some intermittent failures.)

313Imager 0.94_01 - 2 Mar 2013
314==============
315
14a4ea18 316 - NOTE: possibly backward incompatible:
3dcf7595
TC
317 support reading from/writing to perl filehandes that aren't raw
318 files.
319
320 This allows Imager's I/O to honour handles with layers such as
321 gzip, scalar file handles or tied file handles.
322
14a4ea18 323 This is backward incompatible in that previous Imager would simply
3dcf7595
TC
324 use fileno() to retrieve the fd for the file and call write(2) etc
325 on it directly.
04d8c568
TC
326 https://rt.cpan.org/Ticket/Display.html?id=78843
327
328 - moved most of README to lib/Imager/Install.pod which should make it
329 more accessible to the "web" generation, also significantly updated
330 and re-worked it.

c732ffa5
TC
348 - drawing text to a channel with FT2 would draw with random coverage
349 due to an uninitialized alpha channel.
350
351 - marked the function pointer underlying the mm_log() API with the
352 correct gcc magic and fixed the resulting warnings.
353
354 - fixed some other compiler warnings
355

TC
400
401 - previously a transparency enabled GIF write (the default) would
402 always use a GIF89a header even if none of the images were
403 transparent.

424Enhancements:
425
426 - support for giflib 5.0. (5.0.1 and later)
427 https://rt.cpan.org/Ticket/Display.html?id=79029
428 The giflib API Imager uses doesn't have a mechanism to set the
429 header version in 5.0.0.
430
431 - update the GIF library probe code to check for the new giflib 5.0.1
432 EGifSetGifVersion() function, and to check for the giflib 4.2.0
433 uninitialized gif89 bug.

464 - The size of rotated images is no longer rounded up so aggressively.
465 Added rounding to the linear interpolation done for rotate() and
466 matrix_transform() for 1 and 3 channel 8-bit images.
467 Adjusted the two tranlate matrices used to build the final rotation
468 matrix to use the distance between the outlier pixels rather than
469 the pixel dimensions (ie. dimension-1).
470 With all of this the output of rotate(degrees => 270) on an 8-bit
471 image exactly matches the output of rotate(right => 270).

474Other changes:

477 internals, those names only matter for the XS interface.

479 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
480 the API level compiled into a loadable module such as
481 Imager::File::GIF doesn't match that of Imager. Previously it
482 could be difficult to determine exactly which module was failing to
483 load.

504 - when downconverting samples (eg. from floating point to 8 bit)
505 Imager now rounds the sample value rather than attempting to
506 allocate input values over output values equally. The old
507 behaviour had the probably surprising effect of converting a
508 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
509 2.
510 This may result in slightly different 8 or 16-bit output images.

512 - BI_BITFIELD BMP images were handled incorrectly, both in

516
517 - some odd width BMP BI_RLE4 images use run lengths that run one off

540 - if a probe includes testcode, Imager::Probe now checks that code as
541 part of the process of checking each configuration rather than as a
542 post test of the found configuration. This allows alternate
543 configurations to be checked if a matching but non-working
544 configuration is found.

782 - io_glue I/O buffering re-work:
783
784 - reorganize io_glue to do it's own buffering by default
785
786 - the unbuffered functions are available as i_io_raw_read() (or
787 raw_read() from perl) etc but are not recommended for typical
788 use.
789
790 - use the new i_io_peekn() when checking for file magic to avoid
791 seek, allowing Imager to detect the file type and read the file
792 from an unseekable stream (for formats that don't use random
793 access)
794
795 - added several new I/O layer API functions.

801 https://rt.cpan.org/Ticket/Display.html?id=69912
802
803 - the callback IO object did its own buffering, controlled by the
804 maxbuffer parameter supplied to the read() and write() methods.
805 This buffering has been removed, to avoid redundancy with the
806 common io_glue buffering. This also avoids a bug in that code
807 which could rarely pass a zero length to the read callback and
808 then panic about the result.
809
810 - the callback IO object now tests the result of calling the close
811 callback, which should return true for success.
812
813 - the PNM reader did its own buffering. This buffering has been
814 removed to avoid redundancy with the common io_glue buffering.
815
816 - previously the read handlers for fd and callback I/O layers would
817 call the underlying interface (POSIX read or your supplied callback)
818 until it filled the buffer. It now only makes one call.
819
820 - added public constructors for I/O layer objects (see Imager::IO)
821
822 - all core file handlers now use the i_io_foo() wrappers to gain
823 access to buffered I/O rather than calling the I/O layer
824 callbacks directly.
825
826 - all core file handlers now check for error on close.
827
828 - Backward compatibility: if you hava custom file handlers, you can
829 use i_io_write() etc since they're available as macros in older
830 versions of Imager.
831
832 - eliminate the final remnants of io_glue_commit_types().
833
834 - bump IMAGER_API_VERSION, since the above may break assumptions.
835
836 - removed the long unused i_gen_reader() and i_gen_writer() utility

907 - size_t is now used consistently for memory block sizes.
908
909 - since this changes the binary interface, the Imager API version has
910 been incremented. Any module that uses the API will need to be
911 rebuilt. In most cases that will be enough, but calls to any APIs
912 that take a pointer to image sizes may need source changes.
913
914 - you should be able to create very large images on 64-bit systems,
915 if you have enough memory. Successfully created a 32768 x 49192 x
916 3 channel image, filled with a tiled image and scaled it. The
917 unscaled image was also successfully saved to a JPEG.
918
919 - check the image size before attempting to write BMP, GIF, JPEG,
920 PNG, SGI, TGA, TIFF images.
921
922 - correctly handle reading TGA images over 32767 pixels wide or tall.
923
924Incidental changes:
925
926 - the gif_left and gif_top tags are now clamped to non-negative
927 values when writing a GIF image.
928
929 - removed dead callback read/write code
930
931The default maximum memory size when reading files is now 1G.

1378 - the conv filter now enforces that the sum of the coefficients is
1379 non-zero. Also, rather than skipping pixels off the edge off the
1380 edge of the image, the closest edge pixel is used. Previously
1381 dividing by the zero sum of coefficients could cause invalid
1382 results or runtime exceptions.

1578 - moved the imtoc.perl code into Imager::Preprocess

1580 - paste() and rubthrough() now adapt the source image data to the
1581 destination, so you can now safely paste/rubthrough from greyscale
1582 images to color images or back, or from alpha channel images to
1583 noalpha channels or back.
1584 https://rt.cpan.org/Ticket/Display.html?id=30908
1585
1586 - rubthrough() now falls back to pasting when the source doesn't have
1587 an alpha channel. This effectively treats the source as having a
1588 max alpha channel, the right thing to do.
1589 http://rt.cpan.org/Ticket/Display.html?id=29944
1590
1591 - re-worked most of the area filling code to use a common set of
1592 functions when filling.
1593 Corrected normal combine mode.
1594 Rewrote most of the combine modes to match the way the SVG draft
1595 defines them with respect to a translucent source and destination.
1596 Added tests for translucent source and destination.
1597 Added tests to check 8-bit/sample and double/sample combines work
1598 similarly.

1638 changed to match the behaviour of the GIMP. Previously the bit
1639 being set was treated as an opaque pixel, but one user reported a
1640 problem with loading such an image. I haven't been able to find any
1641 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1642 I'll match it's behaviour. See issue 114913 in the GIMP's

1800 - the mask for ICO/CUR images is now applied as an alpha channel to

1961Imager 0.55 - 16 Dec 2006
1962===========
1963
1964This is primarily a bug fix release.
1965
1966Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1967
1968There is one new feature:
1969
1970 - the Win32 font driver now supports UTF8 (RT 22166)
1971 http://www.cpanforum.com/threads/3276
1972 http://rt.cpan.org/Ticket/Display.html?id=22166
1973
1974Several bugs were fixed:
1975
1976 - the string() method would not output the string "0"
1977 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1978
1979 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1980 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1981
1982 - the gif_disposal and gif_user_input tags weren't being read from
1983 the file correctly
1984 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1985
1986 - gif.c was failing to build under MSVC
1987 http://rt.cpan.org/Ticket/Display.html?id=23922
1988
1989 - in some cases strings passed to the string() method were treated as
1990 terminated by NUL (chr 0)
1991 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1992
1993 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1994 that's the default build name for zlib on Win32.
1995 http://rt.cpan.org/Ticket/Display.html?id=23064
1996
1997 - search $Config{incpath} for headers too, which we should have been
1998 doing all along.
1999
2000Win32 font driver fixes:
2001
2002 - the global descent value from bounding box was the wrong sign
2003 http://www.cpanforum.com/threads/3276
2004
2005 - if the first or last glyph overflowed the left or right side of the
2006 advance width they would be clipped
2007
2008
2009Imager 0.54 - 14 Sep 2006
2010===========
2011
2012This is primarily a feature release:
2013
2014 - a new qtype value 'mixing' has been added to the scale()
2015 method. This is faster than 'normal', slower than 'preview'. This
2016 is based on the method used by pnmscale, and seems to produce less
2017 blurry results than normal.
2018 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2019
2020 - the rubthrough() method can now render onto images with an alpha
2021 channel.
2022 http://rt.cpan.org/Ticket/Display.html?id=20678
2023
2024 - the read_multi() method now falls back to calling doing a single
2025 image read via the read() method and write_multi() will now fall
2026 back to calling write() if a single image is supplied. This means
2027 you can simply call the read_multi() or write_multi() functions
2028 without having to check if the type is formatted by that method.
2029 http://rt.cpan.org/Ticket/Display.html?id=19457
2030 http://rt.cpan.org/Ticket/Display.html?id=19458
2031
2032 - the GIF loop extension can now be written. If you don't have
2033 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2034 should upgrade.
2035 http://rt.cpan.org/Ticket/Display.html?id=21185
2036
2037 - getscanline() and setscanline() can now read/write palette index
2038 based data from/to the image for paletted images, by setting type to
2039 'index'.
2040 http://rt.cpan.org/Ticket/Display.html?id=20338
2041
2042 - we no longer hassle you to disable GIF support
2043 http://rt.cpan.org/Ticket/Display.html?id=20687
2044
2045 - minor documentation fixes
2046
2047
2048Imager 0.53 - 26 Jul 2006
2049===========
2050
2051This is a bugfix release.
2052
2053Some test code was left in a code path not covered by the test
2054suite. A test was added to cover this code path and the test code was
2055removed.
2056http://rt.cpan.org/Public/Bug/Display.html?id=20705

2058
2059Imager 0.52 - 25 Jul 2006
2060===========
2061
2062This is primarily a feature release, but contains a fair few bug
2063fixes, new features:
2064
2065 - ability to read and write MS Windows ICO and CUR files
2066
2067 - you can now add file format plugins to support new file formats
2068
2069 - add POD coverage tests
2070
2071 - setcolors() and addcolors() now accept color names and so on
2072 instead of requiring Imager::Color objects.
2073 http://rt.cpan.org/Ticket/Display.html?id=20056
2074
2075 - flood_fill() can now fill to a specified border color instead of
2076 just to the area the same color as the seed.
2077 http://rt.cpan.org/Ticket/Display.html?id=19618
2078
2079
2080Bug fixes:
2081
2082 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2083 calculating the advance width.
2084 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2085
2086 - bounding_box for the T1 driver wasn't including leading and
2087 trailing spaces in the bounding box as the other drivers did, it also
2088 produced strange results for empty strings or strings containing only
2089 spaces
2090
2091 - when reading CMYK jpeg images they were being transferred to the
2092 image object as is, producing a four channel image. It only looked ok
2093 due to an old still unfixed Photoshop bug. We now convert from the
2094 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2095 http://rt.cpan.org/Ticket/Display.html?id=20416
2096
2097 - reading a CYMK TIFF would result in a 4 channel image, reading any
2098 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2099 result in an error.
2100 http://rt.cpan.org/Ticket/Display.html?id=20415
2101
2102 - added /usr/local/include to the default include search path, since
2103 we were already searching /usr/local/lib for libraries.
2104
2105And various minor fixes and documentation updates.
2106
2107
2108Imager 0.51 - 23 Apr 2006
