7b638aba
TC
12 - Imager->new can now be used to read raw image files.

19============
20
0fda3cfd
TC
21 - update 1.002 release notes to include the center change for filled
22 circle drawing.
23
24 - flood_fill() would escape beyond a 4-connected space under some
25 circumstances.
26 Added many more flood_fill() tests.

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

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

96Imager 1.000 - 28 Jul 2014
97============
98
99There's nothing special about Imager 1.000, it's just another release.
100
fa3dac1d
TC

TC
106Imager 0.99_02 - 21 Jul 2014
107==============
108
5dab5b9a
TC
109 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
110 the blue channel in the generated palette, and allow each color
111 component to be in the range 100..255 instead of just 100..254.
112 Thanks to Ralf Neubauer.
113 https://rt.cpan.org/Ticket/Display.html?id=97086
114
115 - revert "improved the XS for i_io_read() and i_io_raw_read()"
116 This caused problems with older perls and didn't provide much of a
117 performance improvement.
118
5bf25bc2 119 - support Inline 0.57 and later.
6d47a6af 120 Inline 0.57 changed the "with" interface.
5bf25bc2
TC
121 https://rt.cpan.org/Ticket/Display.html?id=97108
122
6d47a6af
TC
123 - don't define our own MAXINT macro, it conflicts with windows header
124 files and in a few places it was the wrong value to use anyway.

129
7b486870
TC
130 - GIF: add support for giflib 5.1.0, which added error code pointer
131 parameters to EGifCloseFile() and DGifCloseFile().
132 https://rt.cpan.org/Ticket/Display.html?id=96756
133
134 - GIF: avoid a double-free when do_write() fails.
135
28104a85 136 - fix SV type probing to work on perl before 5.12. Broken in 0.99.

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

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

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

236No changes from 0.96_02.
237

TC
238Imager 0.96_02 - 8 Jul 2013
239==============
240
aaf82685
TC
241 - PNG: treat a version mismatch between headers and library as a
242 probe failure.
243 https://rt.cpan.org/Ticket/Display.html?id=86659
244
8e90f677
TC
245 - PNG: the check for benign error support is more complex than a
246 simple library version check, check for the appropriate macro.
247 Thanks for Slaven Rezic for following up on my CPAN Testers result
248 queries.
249 https://rt.cpan.org/Ticket/Display.html?id=86659
250
f94da9c0
TC
251 - W32: add a missing head1 AUTHORS to the old Win32.pm
252 https://rt.cpan.org/Ticket/Display.html?id=86658
253
d9ae3f2b 254Imager 0.96_01 - 1 Jul 2013

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

face45e7 271 - XS clean up:
29969fa2 272 https://rt.cpan.org/Ticket/Display.html?id=69243
face45e7 273
237d9e03 274 - Imager::Color's rgba() method now returns its values as integers
face45e7
TC
275 instead of floating point. (IV instead of NV).
276
19e9591b
TC
277 - The XS for i_map() and i_matrix_transform() now use the AV *
278 typemap instead of rolling their own.
279
75cebca8
TC
280 - The XS for DSO_call() now uses the HV * typemap instead of
281 rolling it's own.
282
0aaa8b4d
TC
283 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
284 i_gradgen() now use a new T_AVARRAY typemap that greatly
285 simplifies the XS code.
face45e7 286
ccd01d49
TC
287 - many other minor XS changes
288
face45e7 289 - some XS code formatting
a54e32ba 290
dcab59bc
TC
291 - TT (Freetype 1.x) and FT2 (Freetype 2.x) non-antialiased rendering
292 now renders in alpha-combining mode, to match antialiased output.
293 https://rt.cpan.org/Ticket/Display.html?id=73359
b482243a 294
8db7b6fa
TC
295 - add sample code and cookbook notes for drawing a blurred drop-shadow.
296
297 - add support for libpng 1.6, which changed the defaults for
298 reporting some types of error.
299 https://rt.cpan.org/Ticket/Display.html?id=85746
300
dc076f98
TC
301 - FT2: use gsamp/psamp() to transfer pixels from the work image to
302 the output image instead of gpix/ppix.
303 https://rt.cpan.org/Ticket/Display.html?id=83478
304
98747309
TC
305 - eliminate various GCC warnings, mostly initialized but otherwise
306 unused variables.

308Imager 0.96 - 19 May 2013
309===========
310
c2e251d9
TC
311 - rearrange Imager's test files.
312 https://rt.cpan.org/Ticket/Display.html?id=84596
313
314 - Imager::Probe::_gcc_lib_paths now forces C locale.
315 A sufficiently recent gcc prints localized keys for the search
316 paths, which avoids that localization.
317 https://rt.cpan.org/Ticket/Display.html?id=84963
318
319 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
320 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
321 and true.
322 https://rt.cpan.org/Ticket/Display.html?id=85262
323 reported by Andreas König
324

326 found.
327 https://rt.cpan.org/Ticket/Display.html?id=74875
328
329 - fix some spelling errors detected by the newer aspell in Debian
330 Wheezy.
331
332 - remove a trailing ' from lib/Imager/Font/Test.pm's POD
333 thanks to gregor herrmann <gregoa@debian.org>
334 https://rt.cpan.org/Ticket/Display.html?id=85413
335
336 - add a test for standard =head1 commands and fix the errors found

TC
338Imager 0.95 - 19 Apr 2013
339===========
340
0a2956ab
TC
341 - handle the SVf_UTF8 flag correctly on magic strings passed to
342 Imager::IO's write() and raw_write() methods.
343 This may misbehave in perl 5.6.x since the UTF8 flag may not be
344 visible in the main SV after SvGETMAGIC().
345 https://rt.cpan.org/Ticket/Display.html?id=83438
346
347 - document that bounding_box() ignores the transformation matrix
348 supplied to tranform() for fonts.

TC
351Imager 0.94_02 - 5 Apr 2013
352==============
353
1540d1d4
TC
354 - enable debug logging for the standard font tests
355
356 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
357 due to a bug in that version of perl.
358
359 - don't test for read() failing on a write-only handle in 5.8.x and
360 earlier, this was fixed in change 862083f7e4 in perl.
361
362 - report the version of Inline found during testing (an attempt to
363 diagnose some intermittent failures.)

365Imager 0.94_01 - 2 Mar 2013
366==============
367
14a4ea18 368 - NOTE: possibly backward incompatible:
3dcf7595
TC
369 support reading from/writing to perl filehandes that aren't raw
370 files.
371
372 This allows Imager's I/O to honour handles with layers such as
373 gzip, scalar file handles or tied file handles.
374
14a4ea18 375 This is backward incompatible in that previous Imager would simply
3dcf7595
TC
376 use fileno() to retrieve the fd for the file and call write(2) etc
377 on it directly.
04d8c568
TC
378 https://rt.cpan.org/Ticket/Display.html?id=78843
379
380 - moved most of README to lib/Imager/Install.pod which should make it
381 more accessible to the "web" generation, also significantly updated
382 and re-worked it.
3dcf7595 383
ca96f811
TC
384 - updated README's for the separately distributed modules to refer to
385 Imager::Install, and that they need -dev versions of packages
386 https://rt.cpan.org/Ticket/Display.html?id=81265
387
26e8a226
TC
388 - the JPEG test code now reports the compile-time library version

c732ffa5
TC
400 - drawing text to a channel with FT2 would draw with random coverage
401 due to an uninitialized alpha channel.
402
403 - marked the function pointer underlying the mm_log() API with the
404 correct gcc magic and fixed the resulting warnings.
405
406 - fixed some other compiler warnings
407
14a4ea18
TC
408 - Imager::Font::W32 now properly reports text drawing errors

14a4ea18
TC
412 strings passed as text to draw(), bounding_box(), has_chars(),
413 glyph_names() (where supported) in each of the font drivers.
0a2956ab
TC
414 This may misbehave in perl 5.6.x since the UTF8 flag may not be

480 The giflib API Imager uses doesn't have a mechanism to set the

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

526Other changes:

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

TC
556 - when downconverting samples (eg. from floating point to 8 bit)
557 Imager now rounds the sample value rather than attempting to
558 allocate input values over output values equally. The old
559 behaviour had the probably surprising effect of converting a
560 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
561 2.
562 This may result in slightly different 8 or 16-bit output images.

838 - the unbuffered functions are available as i_io_raw_read() (or
839 raw_read() from perl) etc but are not recommended for typical
840 use.
841
842 - use the new i_io_peekn() when checking for file magic to avoid
843 seek, allowing Imager to detect the file type and read the file
844 from an unseekable stream (for formats that don't use random
845 access)

855 - the callback IO object did its own buffering, controlled by the
856 maxbuffer parameter supplied to the read() and write() methods.
857 This buffering has been removed, to avoid redundancy with the
858 common io_glue buffering. This also avoids a bug in that code
859 which could rarely pass a zero length to the read callback and
860 then panic about the result.
861
862 - the callback IO object now tests the result of calling the close
863 callback, which should return true for success.
864
865 - the PNM reader did its own buffering. This buffering has been
866 removed to avoid redundancy with the common io_glue buffering.
867
868 - previously the read handlers for fd and callback I/O layers would
869 call the underlying interface (POSIX read or your supplied callback)
870 until it filled the buffer. It now only makes one call.
871
872 - added public constructors for I/O layer objects (see Imager::IO)
873
874 - all core file handlers now use the i_io_foo() wrappers to gain
875 access to buffered I/O rather than calling the I/O layer
876 callbacks directly.
877
878 - all core file handlers now check for error on close.
879
880 - Backward compatibility: if you hava custom file handlers, you can
881 use i_io_write() etc since they're available as macros in older
882 versions of Imager.
883
884 - eliminate the final remnants of io_glue_commit_types().
885
886 - bump IMAGER_API_VERSION, since the above may break assumptions.
887

950==============
951
952Development release as a sanity check for the types re-work.
8d14daab
TC
953
954Massive types re-work:
955
956 - the type used internally for pixel co-ordinates and image sizes is
957 now 64-bit on 64-bit platforms (at least sane ones).
958
959 - size_t is now used consistently for memory block sizes.
960
961 - since this changes the binary interface, the Imager API version has
962 been incremented. Any module that uses the API will need to be
963 rebuilt. In most cases that will be enough, but calls to any APIs
964 that take a pointer to image sizes may need source changes.
965
966 - you should be able to create very large images on 64-bit systems,
967 if you have enough memory. Successfully created a 32768 x 49192 x
968 3 channel image, filled with a tiled image and scaled it. The
969 unscaled image was also successfully saved to a JPEG.
970
971 - check the image size before attempting to write BMP, GIF, JPEG,
972 PNG, SGI, TGA, TIFF images.
973
974 - correctly handle reading TGA images over 32767 pixels wide or tall.
975
976Incidental changes:
977
978 - the gif_left and gif_top tags are now clamped to non-negative
979 values when writing a GIF image.
980
981 - removed dead callback read/write code
982
983The default maximum memory size when reading files is now 1G.

1637
1638 - rubthrough() now falls back to pasting when the source doesn't have
1639 an alpha channel. This effectively treats the source as having a
1640 max alpha channel, the right thing to do.
1641 http://rt.cpan.org/Ticket/Display.html?id=29944

1647 defines them with respect to a translucent source and destination.

1692 problem with loading such an image. I haven't been able to find any
1693 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so

2013Imager 0.55 - 16 Dec 2006
2014===========
2015
2016This is primarily a bug fix release.
2017
2018Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2019
2020There is one new feature:
2021
2022 - the Win32 font driver now supports UTF8 (RT 22166)
2023 http://www.cpanforum.com/threads/3276
2024 http://rt.cpan.org/Ticket/Display.html?id=22166
2025
2026Several bugs were fixed:
2027
2028 - the string() method would not output the string "0"
2029 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2030
2031 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2032 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2033
2034 - the gif_disposal and gif_user_input tags weren't being read from
2035 the file correctly
2036 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2037
2038 - gif.c was failing to build under MSVC
2039 http://rt.cpan.org/Ticket/Display.html?id=23922
2040
2041 - in some cases strings passed to the string() method were treated as
2042 terminated by NUL (chr 0)
2043 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2044
2045 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2046 that's the default build name for zlib on Win32.
2047 http://rt.cpan.org/Ticket/Display.html?id=23064
2048
2049 - search $Config{incpath} for headers too, which we should have been
2050 doing all along.
2051
2052Win32 font driver fixes:
2053
2054 - the global descent value from bounding box was the wrong sign
2055 http://www.cpanforum.com/threads/3276
2056
2057 - if the first or last glyph overflowed the left or right side of the
2058 advance width they would be clipped
2059
2060
2061Imager 0.54 - 14 Sep 2006
2062===========
2063
2064This is primarily a feature release:
2065
2066 - a new qtype value 'mixing' has been added to the scale()
2067 method. This is faster than 'normal', slower than 'preview'. This
2068 is based on the method used by pnmscale, and seems to produce less
2069 blurry results than normal.
2070 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2071
2072 - the rubthrough() method can now render onto images with an alpha
2073 channel.
2074 http://rt.cpan.org/Ticket/Display.html?id=20678
2075
2076 - the read_multi() method now falls back to calling doing a single
2077 image read via the read() method and write_multi() will now fall
2078 back to calling write() if a single image is supplied. This means
2079 you can simply call the read_multi() or write_multi() functions
2080 without having to check if the type is formatted by that method.
2081 http://rt.cpan.org/Ticket/Display.html?id=19457
2082 http://rt.cpan.org/Ticket/Display.html?id=19458
2083
2084 - the GIF loop extension can now be written. If you don't have
2085 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2086 should upgrade.
2087 http://rt.cpan.org/Ticket/Display.html?id=21185
2088
2089 - getscanline() and setscanline() can now read/write palette index
2090 based data from/to the image for paletted images, by setting type to
2091 'index'.
2092 http://rt.cpan.org/Ticket/Display.html?id=20338
2093
2094 - we no longer hassle you to disable GIF support
2095 http://rt.cpan.org/Ticket/Display.html?id=20687
2096
2097 - minor documentation fixes
2098
2099
2100Imager 0.53 - 26 Jul 2006
2101===========
2102
2103This is a bugfix release.
2104
2105Some test code was left in a code path not covered by the test
2106suite. A test was added to cover this code path and the test code was
2107removed.
2108http://rt.cpan.org/Public/Bug/Display.html?id=20705

2110
2111Imager 0.52 - 25 Jul 2006
2112===========
2113
2114This is primarily a feature release, but contains a fair few bug
2115fixes, new features:
2116
2117 - ability to read and write MS Windows ICO and CUR files
2118
2119 - you can now add file format plugins to support new file formats
2120
2121 - add POD coverage tests
2122
2123 - setcolors() and addcolors() now accept color names and so on
2124 instead of requiring Imager::Color objects.
2125 http://rt.cpan.org/Ticket/Display.html?id=20056
2126
2127 - flood_fill() can now fill to a specified border color instead of
2128 just to the area the same color as the seed.
2129 http://rt.cpan.org/Ticket/Display.html?id=19618
2130
2131
2132Bug fixes:
2133
2134 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2135 calculating the advance width.
2136 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2137
2138 - bounding_box for the T1 driver wasn't including leading and
2139 trailing spaces in the bounding box as the other drivers did, it also
2140 produced strange results for empty strings or strings containing only
2141 spaces
2142
2143 - when reading CMYK jpeg images they were being transferred to the
2144 image object as is, producing a four channel image. It only looked ok
2145 due to an old still unfixed Photoshop bug. We now convert from the
2146 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2147 http://rt.cpan.org/Ticket/Display.html?id=20416
2148
2149 - reading a CYMK TIFF would result in a 4 channel image, reading any
2150 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2151 result in an error.
2152 http://rt.cpan.org/Ticket/Display.html?id=20415
2153
2154 - added /usr/local/include to the default include search path, since
2155 we were already searching /usr/local/lib for libraries.
2156
2157And various minor fixes and documentation updates.
2158
2159
2160Imager 0.51 - 23 Apr 2006
