3 - drawing anti-aliased filled circles is now 10 to 50 times faster
4 depending on the size of the circle.
5 https://rt.cpan.org/Ticket/Display.html?id=101682
6
7 - enhancements to polygon filling:
8
9 - added a mode parameter to control how overlapping regions behave
10
11 - added a polypolygon() method to fill more than one polygon at a
12 time
13
14 - polygon filling is now exposed through the API.
15
45c8e262
TC
16 - added colormodel(), alphachannel() and colorchannels() methods.
17 These were added for two reasons:
18
19 - a future version of Imager may allow the number of channels in
20 an image to not directly represent the color model of an image.
21 eg. a greyscale TIFF image with multiple alpha channels.
22
23 - a future version of Imager may allow an image to be read without
24 translation, for example a TIFF file that contains measurements
25 from an instrument. Currently Image transforms the samples into
26 the range 0.0 ... 1.0 which may means the user has to translates
27 the value back.
28
29 An untranslated image would be unusable as image data, so
30 colormodel() would return "unknown" in this case.
31
32 Similarly a CMYK image might be returned as an "unknown" color
33 model image, if the caller chooses to disable translation to
34 RGB.

TC
77 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
78 the blue channel in the generated palette, and allow each color
79 component to be in the range 100..255 instead of just 100..254.
80 Thanks to Ralf Neubauer.
81 https://rt.cpan.org/Ticket/Display.html?id=97086
82
83 - revert "improved the XS for i_io_read() and i_io_raw_read()"
84 This caused problems with older perls and didn't provide much of a
85 performance improvement.
86
5bf25bc2 87 - support Inline 0.57 and later.
6d47a6af 88 Inline 0.57 changed the "with" interface.

111Imager 0.99 - 25 Jun 2014
112===========
113
dce1523b
TC
114 - Imager::IO->new_buffer() (and hence Imager->read()'s data
115 parameter) now accepts a reference to a scalar as well as just a
116 plain scalar.
6a160bce 117 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
118
119 - Imager::IO->new_buffer() now always makes a copy of the passed in
120 buffer to avoid problems with temporary objects used for the return
121 value of SvPVbyte().
6a160bce 122 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 123

127 - load plugins from absolute paths on Android
128 Thanks to Brian Fraser.
129 https://rt.cpan.org/Ticket/Display.html?id=93272
130
6a160bce
TC
131 - added the jpeg_optimize parameter for writing JPEG files. This can
132 significantly reduce file sizes, but uses more memory and time.
133 https://rt.cpan.org/Ticket/Display.html?id=94292
134
14fd9e5d
TC
135 - the autolevels filter now works on the luminosity of the image
136 rather then working per channel. The old autolevels filter is
137 still available as "autolevels_skew".
138 https://rt.cpan.org/Ticket/Display.html?id=94413
139
75d54149
TC
140 - Imager::File::PNG now supports libpng 1.6.10.
141 1.6.10 changed CRC errors from benign errors to normal errors,
142 which broke the test which used CRC errors to check for benign
143 error support. Switched to using a 1-bit grey-scale image with a
144 palette to test for benign errors.

147Imager 0.98 - 3 Jan 2014
148===========
149
f84f86a2
TC
150Incompatible changes:
151
152 - the return value of setpixel() has changed.
153
154 Previously the return values for undrawable pixels vs caller errors
155 changed depending on whether you used the multiple pixel calling
156 mechanism, or the single pixel mechanism.
157
158 Now:
159
160 - for an invalid parameter, such as an unknown colour, or missing
161 parameter, an empty list (or undef in scalar context) is
162 returned, and errstr() is set,
163
164 - otherwise the number of pixels drawn is returned. If none of
165 the pixels could be drawn (they were all outside the image), "0
166 but true" is returned.
167
168 https://rt.cpan.org/Ticket/Display.html?id=87650
169
170Other changes:
171
6ba09ab9
TC
172 - when drawing on an image with an alpha channel where the source
173 minimum is greater than zero, Imager would read from beyond the end
174 of a malloc() allocated buffer. In rare circumstances this could
175 lead to some of the source image not being written to the target
176 image, or possibly to a segmentation fault.
177 I don't believe this has any security concerns beyond that.
178
0d052fd9
TC
179 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
180 text drawn would be nonsense. This would also read beyond the end
181 of a malloced buffer.
182
13671b17
TC
183 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
184 truncated early.
185 https://rt.cpan.org/Ticket/Display.html?id=88993
186
d6f4e964
TC
187 - Imager::Font::Wrap no longer requires the image parameter.

189
f84f86a2
TC
190 - a documentation typo fix in Imager::Transformations
191 Thanks to Adrian Yee.
192 https://rt.cpan.org/Ticket/Display.html?id=88598
193
0179ecd6
TC
194 - Image::Probe, Imager's internal module for probing library
195 locations now searches the directories specified by LD_RUN_PATH,
196 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
197 and the corresponing s/\blib$/include/ directories for header
198 files.

209 - PNG: treat a version mismatch between headers and library as a
210 probe failure.
211 https://rt.cpan.org/Ticket/Display.html?id=86659
212
8e90f677
TC
213 - PNG: the check for benign error support is more complex than a
214 simple library version check, check for the appropriate macro.
215 Thanks for Slaven Rezic for following up on my CPAN Testers result
216 queries.

TC
225 - TIFF: handle SampleFormat = 2 by translating the signed integer
226 values to unsigned by flipping their sign bits.
227
228 Handle SampleFormat = 3 where possible.
229
230 SampleFormat is ignored for paletted images.
231
237d9e03
TC
232 Mixed SampleFormat are handled incorrectly, since libtiff returns
233 only the first SampleFormat value, and an image with both an alpha
234 channel and SampleFormat = 2 for color channels probably has a
235 different SampleFormat for the alpha channel.

face45e7
TC
243 instead of floating point. (IV instead of NV).
244
19e9591b
TC
245 - The XS for i_map() and i_matrix_transform() now use the AV *
246 typemap instead of rolling their own.
247

TC
248 - The XS for DSO_call() now uses the HV * typemap instead of
249 rolling it's own.
250
0aaa8b4d
TC
251 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
252 i_gradgen() now use a new T_AVARRAY typemap that greatly
253 simplifies the XS code.
face45e7 254

TC
279 - rearrange Imager's test files.
280 https://rt.cpan.org/Ticket/Display.html?id=84596
281
282 - Imager::Probe::_gcc_lib_paths now forces C locale.
283 A sufficiently recent gcc prints localized keys for the search
284 paths, which avoids that localization.
285 https://rt.cpan.org/Ticket/Display.html?id=84963
286
287 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
288 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
289 and true.

307===========
308
0a2956ab
TC
309 - handle the SVf_UTF8 flag correctly on magic strings passed to
310 Imager::IO's write() and raw_write() methods.
311 This may misbehave in perl 5.6.x since the UTF8 flag may not be
312 visible in the main SV after SvGETMAGIC().
313 https://rt.cpan.org/Ticket/Display.html?id=83438

322 - enable debug logging for the standard font tests
323
324 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
325 due to a bug in that version of perl.
326
327 - don't test for read() failing on a write-only handle in 5.8.x and
328 earlier, this was fixed in change 862083f7e4 in perl.

14a4ea18 336 - NOTE: possibly backward incompatible:
3dcf7595
TC
337 support reading from/writing to perl filehandes that aren't raw
338 files.
339
340 This allows Imager's I/O to honour handles with layers such as
341 gzip, scalar file handles or tied file handles.
342
14a4ea18 343 This is backward incompatible in that previous Imager would simply
3dcf7595

344 use fileno() to retrieve the fd for the file and call write(2) etc
345 on it directly.

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

500 the API level compiled into a loadable module such as

524 - when downconverting samples (eg. from floating point to 8 bit)
525 Imager now rounds the sample value rather than attempting to
526 allocate input values over output values equally. The old
527 behaviour had the probably surprising effect of converting a
528 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
529 2.
530 This may result in slightly different 8 or 16-bit output images.

802 - io_glue I/O buffering re-work:

806 - the unbuffered functions are available as i_io_raw_read() (or
807 raw_read() from perl) etc but are not recommended for typical
808 use.
809
810 - use the new i_io_peekn() when checking for file magic to avoid
811 seek, allowing Imager to detect the file type and read the file
812 from an unseekable stream (for formats that don't use random
813 access)

822
823 - the callback IO object did its own buffering, controlled by the
824 maxbuffer parameter supplied to the read() and write() methods.
825 This buffering has been removed, to avoid redundancy with the
826 common io_glue buffering. This also avoids a bug in that code
827 which could rarely pass a zero length to the read callback and
828 then panic about the result.
829
830 - the callback IO object now tests the result of calling the close
831 callback, which should return true for success.
832
833 - the PNM reader did its own buffering. This buffering has been
834 removed to avoid redundancy with the common io_glue buffering.
835
836 - previously the read handlers for fd and callback I/O layers would
837 call the underlying interface (POSIX read or your supplied callback)
838 until it filled the buffer. It now only makes one call.
839
840 - added public constructors for I/O layer objects (see Imager::IO)
841
842 - all core file handlers now use the i_io_foo() wrappers to gain
843 access to buffered I/O rather than calling the I/O layer
844 callbacks directly.
845
846 - all core file handlers now check for error on close.
847
848 - Backward compatibility: if you hava custom file handlers, you can
849 use i_io_write() etc since they're available as macros in older
850 versions of Imager.
851
852 - eliminate the final remnants of io_glue_commit_types().
853
854 - bump IMAGER_API_VERSION, since the above may break assumptions.
855
856 - removed the long unused i_gen_reader() and i_gen_writer() utility

917Imager 0.84_01 - 8 Aug 2011
918==============
919
920Development release as a sanity check for the types re-work.
8d14daab
TC
921
922Massive types re-work:
923
924 - the type used internally for pixel co-ordinates and image sizes is
925 now 64-bit on 64-bit platforms (at least sane ones).
926
927 - size_t is now used consistently for memory block sizes.
928
929 - since this changes the binary interface, the Imager API version has
930 been incremented. Any module that uses the API will need to be
931 rebuilt. In most cases that will be enough, but calls to any APIs
932 that take a pointer to image sizes may need source changes.
933
934 - you should be able to create very large images on 64-bit systems,
935 if you have enough memory. Successfully created a 32768 x 49192 x
936 3 channel image, filled with a tiled image and scaled it. The
937 unscaled image was also successfully saved to a JPEG.
938
939 - check the image size before attempting to write BMP, GIF, JPEG,
940 PNG, SGI, TGA, TIFF images.
941
942 - correctly handle reading TGA images over 32767 pixels wide or tall.
943
944Incidental changes:
945
946 - the gif_left and gif_top tags are now clamped to non-negative
947 values when writing a GIF image.
948
949 - removed dead callback read/write code
950
951The default maximum memory size when reading files is now 1G.

1572 resulting in a SIGSEGV when attempting to scale an image to a size
1573 too large to fit in memory. This is a NULL pointer access issue,

1589This release primarily contains changes to improve ease of use -
1590rather than you having to convert images to the appropriate number of

1598 - moved the imtoc.perl code into Imager::Preprocess

1600 - paste() and rubthrough() now adapt the source image data to the
1601 destination, so you can now safely paste/rubthrough from greyscale
1602 images to color images or back, or from alpha channel images to
1603 noalpha channels or back.
1604 https://rt.cpan.org/Ticket/Display.html?id=30908
1605
1606 - rubthrough() now falls back to pasting when the source doesn't have
1607 an alpha channel. This effectively treats the source as having a
1608 max alpha channel, the right thing to do.
1609 http://rt.cpan.org/Ticket/Display.html?id=29944
1610
1611 - re-worked most of the area filling code to use a common set of
1612 functions when filling.
1613 Corrected normal combine mode.
1614 Rewrote most of the combine modes to match the way the SVG draft
1615 defines them with respect to a translucent source and destination.
1616 Added tests for translucent source and destination.
1617 Added tests to check 8-bit/sample and double/sample combines work
1618 similarly.

1658 changed to match the behaviour of the GIMP. Previously the bit
1659 being set was treated as an opaque pixel, but one user reported a
1660 problem with loading such an image. I haven't been able to find any
1661 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1662 I'll match it's behaviour. See issue 114913 in the GIMP's

1981Imager 0.55 - 16 Dec 2006
1982===========
1983
1984This is primarily a bug fix release.
1985
1986Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1987
1988There is one new feature:
1989
1990 - the Win32 font driver now supports UTF8 (RT 22166)
1991 http://www.cpanforum.com/threads/3276
1992 http://rt.cpan.org/Ticket/Display.html?id=22166
1993
1994Several bugs were fixed:
1995
1996 - the string() method would not output the string "0"
1997 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1998
1999 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2000 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2001
2002 - the gif_disposal and gif_user_input tags weren't being read from
2003 the file correctly
2004 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2005
2006 - gif.c was failing to build under MSVC
2007 http://rt.cpan.org/Ticket/Display.html?id=23922
2008
2009 - in some cases strings passed to the string() method were treated as
2010 terminated by NUL (chr 0)
2011 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2012
2013 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2014 that's the default build name for zlib on Win32.
2015 http://rt.cpan.org/Ticket/Display.html?id=23064
2016
2017 - search $Config{incpath} for headers too, which we should have been
2018 doing all along.
2019
2020Win32 font driver fixes:
2021
2022 - the global descent value from bounding box was the wrong sign
2023 http://www.cpanforum.com/threads/3276
2024
2025 - if the first or last glyph overflowed the left or right side of the
2026 advance width they would be clipped
2027
2028
2029Imager 0.54 - 14 Sep 2006
2030===========
2031
2032This is primarily a feature release:
2033
2034 - a new qtype value 'mixing' has been added to the scale()
2035 method. This is faster than 'normal', slower than 'preview'. This
2036 is based on the method used by pnmscale, and seems to produce less
2037 blurry results than normal.
2038 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2039
2040 - the rubthrough() method can now render onto images with an alpha
2041 channel.
2042 http://rt.cpan.org/Ticket/Display.html?id=20678
2043
2044 - the read_multi() method now falls back to calling doing a single
2045 image read via the read() method and write_multi() will now fall
2046 back to calling write() if a single image is supplied. This means
2047 you can simply call the read_multi() or write_multi() functions
2048 without having to check if the type is formatted by that method.
2049 http://rt.cpan.org/Ticket/Display.html?id=19457
2050 http://rt.cpan.org/Ticket/Display.html?id=19458
2051
2052 - the GIF loop extension can now be written. If you don't have
2053 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2054 should upgrade.
2055 http://rt.cpan.org/Ticket/Display.html?id=21185
2056
2057 - getscanline() and setscanline() can now read/write palette index
2058 based data from/to the image for paletted images, by setting type to
2059 'index'.
2060 http://rt.cpan.org/Ticket/Display.html?id=20338
2061
2062 - we no longer hassle you to disable GIF support
2063 http://rt.cpan.org/Ticket/Display.html?id=20687
2064
2065 - minor documentation fixes
2066
2067
2068Imager 0.53 - 26 Jul 2006
2069===========
2070
2071This is a bugfix release.
2072
2073Some test code was left in a code path not covered by the test
2074suite. A test was added to cover this code path and the test code was
2075removed.
2076http://rt.cpan.org/Public/Bug/Display.html?id=20705
2077
2078
2079Imager 0.52 - 25 Jul 2006
2080===========
2081
2082This is primarily a feature release, but contains a fair few bug
2083fixes, new features:
2084
2085 - ability to read and write MS Windows ICO and CUR files
2086
2087 - you can now add file format plugins to support new file formats
2088
2089 - add POD coverage tests
2090
2091 - setcolors() and addcolors() now accept color names and so on
2092 instead of requiring Imager::Color objects.
2093 http://rt.cpan.org/Ticket/Display.html?id=20056
2094
2095 - flood_fill() can now fill to a specified border color instead of
2096 just to the area the same color as the seed.
2097 http://rt.cpan.org/Ticket/Display.html?id=19618
2098
2099
2100Bug fixes:
2101
2102 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2103 calculating the advance width.
2104 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2105
2106 - bounding_box for the T1 driver wasn't including leading and
2107 trailing spaces in the bounding box as the other drivers did, it also
2108 produced strange results for empty strings or strings containing only
2109 spaces
2110
2111 - when reading CMYK jpeg images they were being transferred to the
2112 image object as is, producing a four channel image. It only looked ok
2113 due to an old still unfixed Photoshop bug. We now convert from the
2114 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2115 http://rt.cpan.org/Ticket/Display.html?id=20416
2116
2117 - reading a CYMK TIFF would result in a 4 channel image, reading any
2118 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2119 result in an error.
2120 http://rt.cpan.org/Ticket/Display.html?id=20415
2121
2122 - added /usr/local/include to the default include search path, since
2123 we were already searching /usr/local/lib for libraries.
2124
2125And various minor fixes and documentation updates.
2126
2127
2128Imager 0.51 - 23 Apr 2006

2149 output is an in-memeory buffer.
