15Imager 1.003 - 12 May 2015
16============
17
0fda3cfd
TC
18 - update 1.002 release notes to include the center change for filled
19 circle drawing.
20
21 - flood_fill() would escape beyond a 4-connected space under some
22 circumstances.
23 Added many more flood_fill() tests.

26Imager 1.002 - 3 Apr 2015
27============
28
334b8922
TC
29 - drawing anti-aliased filled circles is now 10 to 50 times faster
30 depending on the size of the circle.
0fda3cfd
TC
31 This also changed the center from being the center of the pixel to
32 being the top left of the pixel to match the filled arcs drawn by
33 arc().

TC
34 https://rt.cpan.org/Ticket/Display.html?id=101682
35
36 - enhancements to polygon filling:
37
38 - added a mode parameter to control how overlapping regions behave
39
40 - added a polypolygon() method to fill more than one polygon at a
41 time
42
43 - polygon filling is now exposed through the API.
44
45c8e262
TC
45 - added colormodel(), alphachannel() and colorchannels() methods.
46 These were added for two reasons:
47
48 - a future version of Imager may allow the number of channels in
49 an image to not directly represent the color model of an image.
50 eg. a greyscale TIFF image with multiple alpha channels.
51
52 - a future version of Imager may allow an image to be read without
53 translation, for example a TIFF file that contains measurements
0fda3cfd 54 from an instrument. Currently Imager transforms the samples into
45c8e262
TC
55 the range 0.0 ... 1.0 which may means the user has to translates
56 the value back.
57
58 An untranslated image would be unusable as image data, so
59 colormodel() would return "unknown" in this case.
60
61 Similarly a CMYK image might be returned as an "unknown" color
62 model image, if the caller chooses to disable translation to
63 RGB.

TC
103Imager 0.99_02 - 21 Jul 2014
104==============
105
5dab5b9a
TC
106 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
107 the blue channel in the generated palette, and allow each color
108 component to be in the range 100..255 instead of just 100..254.
109 Thanks to Ralf Neubauer.
110 https://rt.cpan.org/Ticket/Display.html?id=97086
111
112 - revert "improved the XS for i_io_read() and i_io_raw_read()"
113 This caused problems with older perls and didn't provide much of a
114 performance improvement.
115
5bf25bc2 116 - support Inline 0.57 and later.
6d47a6af 117 Inline 0.57 changed the "with" interface.

6d47a6af
TC
120 - don't define our own MAXINT macro, it conflicts with windows header
121 files and in a few places it was the wrong value to use anyway.

126
7b486870
TC
127 - GIF: add support for giflib 5.1.0, which added error code pointer
128 parameters to EGifCloseFile() and DGifCloseFile().
129 https://rt.cpan.org/Ticket/Display.html?id=96756
130
131 - GIF: avoid a double-free when do_write() fails.
132
28104a85 133 - fix SV type probing to work on perl before 5.12. Broken in 0.99.

136 - PNG: skip the benign error test before libpng 1.6.0, since the
137 error we're testing didn't exist before 1.6.0.

140Imager 0.99 - 25 Jun 2014
141===========
142
dce1523b
TC
143 - Imager::IO->new_buffer() (and hence Imager->read()'s data
144 parameter) now accepts a reference to a scalar as well as just a
145 plain scalar.
6a160bce 146 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
147
148 - Imager::IO->new_buffer() now always makes a copy of the passed in
149 buffer to avoid problems with temporary objects used for the return
150 value of SvPVbyte().
6a160bce 151 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 152
c757e211
TC
153 - improved the XS for i_io_read() and i_io_raw_read()
154 https://rt.cpan.org/Ticket/Display.html?id=92738
155
156 - load plugins from absolute paths on Android
157 Thanks to Brian Fraser.
158 https://rt.cpan.org/Ticket/Display.html?id=93272
159
6a160bce
TC
160 - added the jpeg_optimize parameter for writing JPEG files. This can
161 significantly reduce file sizes, but uses more memory and time.
162 https://rt.cpan.org/Ticket/Display.html?id=94292
163
14fd9e5d
TC
164 - the autolevels filter now works on the luminosity of the image
165 rather then working per channel. The old autolevels filter is
166 still available as "autolevels_skew".
167 https://rt.cpan.org/Ticket/Display.html?id=94413
168
75d54149
TC
169 - Imager::File::PNG now supports libpng 1.6.10.
170 1.6.10 changed CRC errors from benign errors to normal errors,
171 which broke the test which used CRC errors to check for benign
172 error support. Switched to using a 1-bit grey-scale image with a
173 palette to test for benign errors.
174 https://rt.cpan.org/Ticket/Display.html?id=94717

TC
176Imager 0.98 - 3 Jan 2014
177===========
178
f84f86a2
TC
179Incompatible changes:
180
181 - the return value of setpixel() has changed.
182
183 Previously the return values for undrawable pixels vs caller errors
184 changed depending on whether you used the multiple pixel calling
185 mechanism, or the single pixel mechanism.
186
187 Now:
188
189 - for an invalid parameter, such as an unknown colour, or missing
190 parameter, an empty list (or undef in scalar context) is
191 returned, and errstr() is set,
192
193 - otherwise the number of pixels drawn is returned. If none of
194 the pixels could be drawn (they were all outside the image), "0
195 but true" is returned.
196
197 https://rt.cpan.org/Ticket/Display.html?id=87650
198
199Other changes:
200
6ba09ab9
TC
201 - when drawing on an image with an alpha channel where the source
202 minimum is greater than zero, Imager would read from beyond the end
203 of a malloc() allocated buffer. In rare circumstances this could
204 lead to some of the source image not being written to the target
205 image, or possibly to a segmentation fault.
206 I don't believe this has any security concerns beyond that.
207
0d052fd9
TC
208 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
209 text drawn would be nonsense. This would also read beyond the end
210 of a malloced buffer.
211
13671b17
TC
212 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
213 truncated early.
214 https://rt.cpan.org/Ticket/Display.html?id=88993
215
d6f4e964
TC
216 - Imager::Font::Wrap no longer requires the image parameter.
217 https://rt.cpan.org/Ticket/Display.html?id=87338
218
f84f86a2
TC
219 - a documentation typo fix in Imager::Transformations
220 Thanks to Adrian Yee.
221 https://rt.cpan.org/Ticket/Display.html?id=88598
222
0179ecd6
TC
223 - Image::Probe, Imager's internal module for probing library
224 locations now searches the directories specified by LD_RUN_PATH,
225 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
226 and the corresponing s/\blib$/include/ directories for header
227 files.

TC
235Imager 0.96_02 - 8 Jul 2013
236==============
237
aaf82685
TC
238 - PNG: treat a version mismatch between headers and library as a
239 probe failure.
240 https://rt.cpan.org/Ticket/Display.html?id=86659
241
8e90f677
TC
242 - PNG: the check for benign error support is more complex than a
243 simple library version check, check for the appropriate macro.
244 Thanks for Slaven Rezic for following up on my CPAN Testers result
245 queries.
246 https://rt.cpan.org/Ticket/Display.html?id=86659
247
f94da9c0
TC
248 - W32: add a missing head1 AUTHORS to the old Win32.pm
249 https://rt.cpan.org/Ticket/Display.html?id=86658
250
d9ae3f2b 251Imager 0.96_01 - 1 Jul 2013

TC
252==============
253
05c9b356
TC
254 - TIFF: handle SampleFormat = 2 by translating the signed integer
255 values to unsigned by flipping their sign bits.
256
257 Handle SampleFormat = 3 where possible.
258
259 SampleFormat is ignored for paletted images.
260
237d9e03
TC
261 Mixed SampleFormat are handled incorrectly, since libtiff returns
262 only the first SampleFormat value, and an image with both an alpha
263 channel and SampleFormat = 2 for color channels probably has a
264 different SampleFormat for the alpha channel.

face45e7 268 - XS clean up:
29969fa2 269 https://rt.cpan.org/Ticket/Display.html?id=69243
face45e7 270
237d9e03 271 - Imager::Color's rgba() method now returns its values as integers
face45e7
TC
272 instead of floating point. (IV instead of NV).
273
19e9591b
TC
274 - The XS for i_map() and i_matrix_transform() now use the AV *
275 typemap instead of rolling their own.
276
75cebca8
TC
277 - The XS for DSO_call() now uses the HV * typemap instead of
278 rolling it's own.
279
0aaa8b4d
TC
280 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
281 i_gradgen() now use a new T_AVARRAY typemap that greatly
282 simplifies the XS code.
face45e7 283
ccd01d49
TC
284 - many other minor XS changes
285
face45e7 286 - some XS code formatting
a54e32ba 287
dcab59bc
TC
288 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
289 now renders in alpha-combining mode, to match antialiased output.
290 https://rt.cpan.org/Ticket/Display.html?id=73359
b482243a 291
8db7b6fa
TC
292 - add sample code and cookbook notes for drawing a blurred drop-shadow.
293
294 - add support for libpng 1.6, which changed the defaults for
295 reporting some types of error.
296 https://rt.cpan.org/Ticket/Display.html?id=85746
297
dc076f98
TC
298 - FT2: use gsamp/psamp() to transfer pixels from the work image to
299 the output image instead of gpix/ppix.
300 https://rt.cpan.org/Ticket/Display.html?id=83478

307
c2e251d9
TC
308 - rearrange Imager's test files.
309 https://rt.cpan.org/Ticket/Display.html?id=84596
310
311 - Imager::Probe::_gcc_lib_paths now forces C locale.
312 A sufficiently recent gcc prints localized keys for the search
313 paths, which avoids that localization.
314 https://rt.cpan.org/Ticket/Display.html?id=84963
315
316 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
317 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
318 and true.
319 https://rt.cpan.org/Ticket/Display.html?id=85262
320 reported by Andreas König

325
326 - fix some spelling errors detected by the newer aspell in Debian
327 Wheezy.
328
329 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
330 thanks to gregor herrmann <gregoa@debian.org>

TC
335Imager 0.95 - 19 Apr 2013
336===========
337
0a2956ab
TC
338 - handle the SVf_UTF8 flag correctly on magic strings passed to
339 Imager::IO's write() and raw_write() methods.
340 This may misbehave in perl 5.6.x since the UTF8 flag may not be
341 visible in the main SV after SvGETMAGIC().
342 https://rt.cpan.org/Ticket/Display.html?id=83438
343
344 - document that bounding_box() ignores the transformation matrix
345 supplied to tranform() for fonts.

TC
351 - enable debug logging for the standard font tests
352
353 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
354 due to a bug in that version of perl.
355
356 - don't test for read() failing on a write-only handle in 5.8.x and
357 earlier, this was fixed in change 862083f7e4 in perl.
358
359 - report the version of Inline found during testing (an attempt to
360 diagnose some intermittent failures.)

362Imager 0.94_01 - 2 Mar 2013
363==============
364
14a4ea18 365 - NOTE: possibly backward incompatible:
3dcf7595
TC
366 support reading from/writing to perl filehandes that aren't raw
367 files.
368
369 This allows Imager's I/O to honour handles with layers such as
370 gzip, scalar file handles or tied file handles.
371
14a4ea18 372 This is backward incompatible in that previous Imager would simply
3dcf7595
TC
373 use fileno() to retrieve the fd for the file and call write(2) etc
374 on it directly.
04d8c568
TC
375 https://rt.cpan.org/Ticket/Display.html?id=78843
376
377 - moved most of README to lib/Imager/Install.pod which should make it

TC
397 - drawing text to a channel with FT2 would draw with random coverage
398 due to an uninitialized alpha channel.

448Bug fixes:
71fbe41a
TC
449
450 - previously a transparency enabled GIF write (the default) would

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

523Other changes:

528 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
529 the API level compiled into a loadable module such as
530 Imager::File::GIF doesn't match that of Imager. Previously it
531 could be difficult to determine exactly which module was failing to

TC
553 - when downconverting samples (eg. from floating point to 8 bit)
554 Imager now rounds the sample value rather than attempting to
555 allocate input values over output values equally. The old
556 behaviour had the probably surprising effect of converting a
557 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
558 2.
559 This may result in slightly different 8 or 16-bit output images.

831 - io_glue I/O buffering re-work:
832
833 - reorganize io_glue to do it's own buffering by default
834
835 - the unbuffered functions are available as i_io_raw_read() (or
836 raw_read() from perl) etc but are not recommended for typical
837 use.
838
839 - use the new i_io_peekn() when checking for file magic to avoid
840 seek, allowing Imager to detect the file type and read the file
841 from an unseekable stream (for formats that don't use random
842 access)

851
852 - the callback IO object did its own buffering, controlled by the
853 maxbuffer parameter supplied to the read() and write() methods.
854 This buffering has been removed, to avoid redundancy with the
855 common io_glue buffering. This also avoids a bug in that code
856 which could rarely pass a zero length to the read callback and
857 then panic about the result.
858
859 - the callback IO object now tests the result of calling the close
860 callback, which should return true for success.
861
862 - the PNM reader did its own buffering. This buffering has been
863 removed to avoid redundancy with the common io_glue buffering.
864
865 - previously the read handlers for fd and callback I/O layers would
866 call the underlying interface (POSIX read or your supplied callback)
867 until it filled the buffer. It now only makes one call.
868
869 - added public constructors for I/O layer objects (see Imager::IO)
870
871 - all core file handlers now use the i_io_foo() wrappers to gain
872 access to buffered I/O rather than calling the I/O layer
873 callbacks directly.
874
875 - all core file handlers now check for error on close.
876
877 - Backward compatibility: if you hava custom file handlers, you can
878 use i_io_write() etc since they're available as macros in older
879 versions of Imager.
880
881 - eliminate the final remnants of io_glue_commit_types().
882
883 - bump IMAGER_API_VERSION, since the above may break assumptions.
884
885 - removed the long unused i_gen_reader() and i_gen_writer() utility

946Imager 0.84_01 - 8 Aug 2011
947==============
948
949Development release as a sanity check for the types re-work.
8d14daab
TC
950
951Massive types re-work:
952
953 - the type used internally for pixel co-ordinates and image sizes is
954 now 64-bit on 64-bit platforms (at least sane ones).
955
956 - size_t is now used consistently for memory block sizes.
957
958 - since this changes the binary interface, the Imager API version has
959 been incremented. Any module that uses the API will need to be
960 rebuilt. In most cases that will be enough, but calls to any APIs
961 that take a pointer to image sizes may need source changes.
962
963 - you should be able to create very large images on 64-bit systems,
964 if you have enough memory. Successfully created a 32768 x 49192 x
965 3 channel image, filled with a tiled image and scaled it. The
966 unscaled image was also successfully saved to a JPEG.
967
968 - check the image size before attempting to write BMP, GIF, JPEG,
969 PNG, SGI, TGA, TIFF images.
970
971 - correctly handle reading TGA images over 32767 pixels wide or tall.
972
973Incidental changes:
974
975 - the gif_left and gif_top tags are now clamped to non-negative
976 values when writing a GIF image.
977
978 - removed dead callback read/write code
979
980The default maximum memory size when reading files is now 1G.

1627 - moved the imtoc.perl code into Imager::Preprocess

1632 noalpha channels or back.
1633 https://rt.cpan.org/Ticket/Display.html?id=30908
1634
1635 - rubthrough() now falls back to pasting when the source doesn't have
1636 an alpha channel. This effectively treats the source as having a
1637 max alpha channel, the right thing to do.
1638 http://rt.cpan.org/Ticket/Display.html?id=29944

1643 Rewrote most of the combine modes to match the way the SVG draft
1644 defines them with respect to a translucent source and destination.

1689 problem with loading such an image. I haven't been able to find any
1690 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so

1849 - the mask for ICO/CUR images is now applied as an alpha channel to
1850 the returned image. For the old behaviour, supply ico_masked => 0

2010Imager 0.55 - 16 Dec 2006
2011===========
2012
2013This is primarily a bug fix release.
2014
2015Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2016
2017There is one new feature:
2018
2019 - the Win32 font driver now supports UTF8 (RT 22166)
2020 http://www.cpanforum.com/threads/3276
2021 http://rt.cpan.org/Ticket/Display.html?id=22166
2022
2023Several bugs were fixed:
2024
2025 - the string() method would not output the string "0"
2026 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2027
2028 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2029 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2030
2031 - the gif_disposal and gif_user_input tags weren't being read from
2032 the file correctly
2033 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2034
2035 - gif.c was failing to build under MSVC
2036 http://rt.cpan.org/Ticket/Display.html?id=23922
2037
2038 - in some cases strings passed to the string() method were treated as
2039 terminated by NUL (chr 0)
2040 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2041
2042 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2043 that's the default build name for zlib on Win32.
2044 http://rt.cpan.org/Ticket/Display.html?id=23064
2045
2046 - search $Config{incpath} for headers too, which we should have been
2047 doing all along.
2048
2049Win32 font driver fixes:
2050
2051 - the global descent value from bounding box was the wrong sign
2052 http://www.cpanforum.com/threads/3276
2053
2054 - if the first or last glyph overflowed the left or right side of the
2055 advance width they would be clipped
2056
2057
2058Imager 0.54 - 14 Sep 2006
2059===========
2060
2061This is primarily a feature release:
2062
2063 - a new qtype value 'mixing' has been added to the scale()
2064 method. This is faster than 'normal', slower than 'preview'. This
2065 is based on the method used by pnmscale, and seems to produce less
2066 blurry results than normal.
2067 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2068
2069 - the rubthrough() method can now render onto images with an alpha
2070 channel.
2071 http://rt.cpan.org/Ticket/Display.html?id=20678
2072
2073 - the read_multi() method now falls back to calling doing a single
2074 image read via the read() method and write_multi() will now fall
2075 back to calling write() if a single image is supplied. This means
2076 you can simply call the read_multi() or write_multi() functions
2077 without having to check if the type is formatted by that method.
2078 http://rt.cpan.org/Ticket/Display.html?id=19457
2079 http://rt.cpan.org/Ticket/Display.html?id=19458
2080
2081 - the GIF loop extension can now be written. If you don't have
2082 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2083 should upgrade.
2084 http://rt.cpan.org/Ticket/Display.html?id=21185
2085
2086 - getscanline() and setscanline() can now read/write palette index
2087 based data from/to the image for paletted images, by setting type to
2088 'index'.
2089 http://rt.cpan.org/Ticket/Display.html?id=20338
2090
2091 - we no longer hassle you to disable GIF support
2092 http://rt.cpan.org/Ticket/Display.html?id=20687
2093
2094 - minor documentation fixes
2095
2096
2097Imager 0.53 - 26 Jul 2006
2098===========
2099
2100This is a bugfix release.
2101
2102Some test code was left in a code path not covered by the test
2103suite. A test was added to cover this code path and the test code was
2104removed.
2105http://rt.cpan.org/Public/Bug/Display.html?id=20705
2106
2107
2108Imager 0.52 - 25 Jul 2006
2109===========
2110
2111This is primarily a feature release, but contains a fair few bug
2112fixes, new features:
2113
2114 - ability to read and write MS Windows ICO and CUR files
2115
2116 - you can now add file format plugins to support new file formats
2117
2118 - add POD coverage tests
2119
2120 - setcolors() and addcolors() now accept color names and so on
2121 instead of requiring Imager::Color objects.
2122 http://rt.cpan.org/Ticket/Display.html?id=20056
2123
2124 - flood_fill() can now fill to a specified border color instead of
2125 just to the area the same color as the seed.
2126 http://rt.cpan.org/Ticket/Display.html?id=19618
2127
2128
2129Bug fixes:
2130
2131 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2132 calculating the advance width.
2133 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2134
2135 - bounding_box for the T1 driver wasn't including leading and
2136 trailing spaces in the bounding box as the other drivers did, it also
2137 produced strange results for empty strings or strings containing only
2138 spaces
2139
2140 - when reading CMYK jpeg images they were being transferred to the
2141 image object as is, producing a four channel image. It only looked ok
2142 due to an old still unfixed Photoshop bug. We now convert from the
2143 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2144 http://rt.cpan.org/Ticket/Display.html?id=20416
2145
2146 - reading a CYMK TIFF would result in a 4 channel image, reading any
2147 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2148 result in an error.
2149 http://rt.cpan.org/Ticket/Display.html?id=20415
2150
2151 - added /usr/local/include to the default include search path, since
2152 we were already searching /usr/local/lib for libraries.
2153
2154And various minor fixes and documentation updates.
2155
2156
2157Imager 0.51 - 23 Apr 2006
