1791cbdb
TC
3Coverity finally finished a build, fix a few problems:
4
8445279e
TC
5High severity:
6
1791cbdb 7 - reading a color-mapped TGA file with an id string would cause a
8445279e 8 double-free if the palette was truncated. CID 185317.
1791cbdb 9
6494c395
TC
10 - mixing scaling to sizes where the accumulator row, the working
11 output row or the working input row didn't fit into the address
12 space could result in memory leaks. This can probably only be
8445279e 13 reproduced on very wide floating-point sample images. CID 185318.
6494c395 14
fc24ca5f 15 - convert an array style function parameter pointer to pointer style
3d7b055c 16 to prevent confusing Coverity in the T1 bounding box implementation.
8445279e 17 CID 185343.
3d7b055c 18
8445279e 19 - Similarly in the FT1 bounding box implementation. CID 185338.
fc24ca5f 20
20c297d4 21 - Similarly for the i_tt_rasterize() function in the FT1
8445279e 22 implementation. CID 185303.
20c297d4 23
fc24ca5f 24 - initialize a pointer to prevent Coverity complaining in polygon
8445279e 25 drawing (it should always end up being set.) CID 185341.
fc24ca5f 26
f7675b46 27 - addi style makemap could potentially read one past the end of an
8445279e 28 array. CID 185337.
f7675b46 29
58ec1fde
TC
30 - supplying a numeric hatch of 32 to Imager::Fill->new(hatch => ...)
31 would result in read beyond the end of the built-in hatch array.
32 Negative values (which Coverity didn't complain about) could also
8445279e 33 cause problems. CID 185331.
58ec1fde 34
b7346865
TC
35 - the Imager::Color set_internal() interal method no longer
36 calls the over-complicated ICL_set_internal() (which is retained
37 only for the old API.) Coverity complained that this leaked, but
38 this could only occur with an invalid (NULL pointer) color object.
8445279e 39 CID 185323.
b7346865 40
785364c1
TC
41 - the underlying implementation of the map() method could read before
42 the beginning on an allocated array if supplied with inconsistent
43 parameters, which Coverity complained about. No Imager code calls
44 that function with inconsistent parameters, but a
8445279e 45 belt-and-suspenders check was added. CID 185315.
785364c1 46
eb7e48c9
TC
47 - Coverity complained a call to i_getcolors(), used by the
48 implementation of the is_bilevel() method could leave the fetched
8445279e 49 colors uninitialized. Added a return value check. CID 185308.
eb7e48c9 50
c1c8b1e9
TC
51 - a numeric combining mode of 13 (eg. as a parameter to
52 Imager::Fill->new())could cause an invalid array read in
53 i_get_combine() due to a fencepost error in validating the combine
8445279e 54 number. CID 185299.
c1c8b1e9 55
c4fd43be
TC
56
57
58 - avoid an unneeded EXTEND() call when the FT1 has_chars()
59 implementation returns 0. CID 185350.
60
61 - avoid accessing a possibly NULL map from MakeMapObject() in a
62 logging call. (GIF) CID 185296.
63
4615ad8d
TC
64 - gradgen() allocated the wrong amount of space (always too much) for
65 the color array. CID 185291.
66
ea3099db
TC
67 - avoid dead code in i_tt_glyph_names(). CID 185321.
68
8b810590
TC
69 - avoid dead code in i_get_anonymous_color_histo(), which is the
70 implementation of getcolorusage(). CID 185327.
71
4eb9a521
TC
72 - avoid dead code in i_ft2_glyph_name(), which is the implementation
73 of glyph_names() for FT2. CID 185342.
74
e7772cea
TC
75 - avoid an unneeded EXTEND() call when the FT2 has_chars()
76 implementation returns 0. CID 185292.
77
596f3eee
TC
78 - the unpack code for ICO/CUR file handling could extend 32-bit
79 unsigned values to 64-bit signed. I believe this is harmless. CID
80 185319.
81
a2ca2b80
TC
82 - remove an unneeded check when terminating the stream for JPEG
83 writing. CID 185347.

85Imager 1.008 - 31 Dec 2018
86============
87
75e155e1 88 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
89 This allows file formats that store EXIF data as blobs similarly
90 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 91
b5bbf161 92 - added some more file extensions to image file type mappings
75e155e1
TC
93
94 - added add_type_extensions() class method
95

TC
110Imager 1.006 - 26 Aug 2017
111============
112
ba7ddbae
TC
113 - the internal i_errors() function now correctly allocates the stack
114 space needed for its result.
115 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
116
117 - t/100-base/020-color.t now uses Imager::Test's test functions
118 instead of its own.
119 https://rt.cpan.org/Ticket/Display.html?id=111993
120
344dda51
TC
121 - write_multi() now returns an error result (a false value) if called
122 with a non-(Imager image object). Previously it would typically
123 crash.
124 https://rt.cpan.org/Ticket/Display.html?id=117878
125
126 - improve the documentation of the jpegquality parameter when
127 writing JPEG files.
128
129 - add code to mitigate CVE-2016-1238, Imager will no longer search the
130 default current directory entry in @INC when searching for file
131 format support modules.

TC
133Imager 1.005 - 16 Apr 2016
134============
135
136It's now been ten years since I switched to the new Changes file in
137release 0.55.
138
cd0109d8
TC
139 - revert the ivdformat probes, they don't work as is and trying to
140 fix them is too much work for now.
141
6f1cbfed
TC
142Imager 1.004_004 - 15 Apr 2016
143================
144
9c45cc49
TC
145 - test that the ivdformat from Config is correct and look for a valid
146 one if it isn't.
147 For the strange Win32 failures.
148
149 - fix a copy and paste error in pod in samples/samp-form.cgi
150
5cea6ea1
TC
151Imager 1.004_003 - 23 Mar 2016
152================
153
bd2d657d
TC
154 - add some extra error reporting to the I/O layers tests, this might
155 help catch a failure seen on Win32.

TC
158Imager 1.004_002 - 20 Mar 2016
159================
160
735b3e7b
TC
161 - don't use the seek() method on opened() handles in
162 t/200-file/400-basic.t. In older versions of perl such handles are
163 only IO::Handle objects, not IO::File, and don't have a seek()
164 method.
165

TC
166Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
167================
168
08914ed1
TC
169 - re-work the t/200-file/400-basic.t to correctly handle failures
170 It's custom ok() function didn't have a prototype and didn't use scalar().
171 This caused ok() to use the note instead of the value being tested when
172 the method called returned an empty list. For an example of the problem
e6226ce5 173 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 174
a2791e47
TC
175 - remove some noise from when Imager tried to work with bugs in old
176 versions of giflib. I can't do much about the new bugs.
08914ed1 177
e6226ce5
TC
178 - the new autolevels filter (Imager 0.99) used an integer for the
179 sample scaling factor which caused the top output level to be too
180 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
181 https://rt.cpan.org/Ticket/Display.html?id=111871
182
e6226ce5 183 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
184 minimum and maximum luminance from the histogram. This slightly
185 reduced the contrast of the output image.
186 https://rt.cpan.org/Ticket/Display.html?id=111871
187
188 - the new autolevels filter now uses a lookup table for 8-bit images
189 to avoid a floating point multiply for each sample.
190 https://rt.cpan.org/Ticket/Display.html?id=111871
191
e6226ce5
TC
192 - fixed several memory leaks detected by valgrind:
193
194 - addcolors() leaked the temporary array of colors supplied to the
195 internal API
196
197 - make_palette() leaked the temporary image array (not the images
198 themselves) passed to the internal API.
199
200 - combine()/i_combine() leaked its working row buffers
201
202 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
203 buffer if there were too many colors
204
205 - getcolorcount()/i_count_colors() leaked the sample buffer if
206 there were too many colors.
207
208 - the nearest_color filter (undocumented until I find a use for it)
209 leaked both temporaries passed to the API and internal buffers
210
a2791e47
TC
211 - the internal process of upgrading a paletted image to a direct
212 color image would leak a context object reference count.
213
214 - a write failure when writing to a GIF file could leak memory.
215
216 - failing to write to a 1-bit/pixel ICO image could leak memory.
217
218 - Imager no longer deliberately leaks the context object from the
219 initial thread. This was done to ensure there was always a context
220 object available, but the code that needed that now handles the
221 lack correctly,
222
e6226ce5
TC
223 - fixed some uninitialized memory usage detected by valgrind:
224
225 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
226 i_matrix_transform_bg() didn't initialize a working color value
227 if there was zero pixel coverage.
228
229 - i_ft2_cp() didn't initialize the complete color when producing an
230 intermediate image. This caused uninitialized value usage when
231 logging the color.
08914ed1 232

TC
233Imager 1.004 - 8 Nov 2015
234============
235
5ebfb369
TC
236 - Imager::Color::Table is now pre-loaded by the preload() method.
237 https://rt.cpan.org/Ticket/Display.html?id=104896
238
239 - fix an assertion triggered under perl 5.23.4.
240 Thanks to A. Sinan Unur for the report and the patch.
241
7b638aba
TC
242 - Imager->new can now be used to read raw image files.
243 https://rt.cpan.org/Ticket/Display.html?id=106836
f7160b21 244 Thanks to Richard Kelsch for reporting this.
7b638aba
TC
245
246 - deal with output changes from Pod::Spell

0d1baac8
TC
249Imager 1.003 - 12 May 2015
250============
251
0fda3cfd
TC
252 - update 1.002 release notes to include the center change for filled
253 circle drawing.
254
255 - flood_fill() would escape beyond a 4-connected space under some
256 circumstances.
257 Added many more flood_fill() tests.

259
647a47c9
TC
260Imager 1.002 - 3 Apr 2015
261============
262
334b8922
TC
263 - drawing anti-aliased filled circles is now 10 to 50 times faster
264 depending on the size of the circle.
0fda3cfd
TC
265 This also changed the center from being the center of the pixel to
266 being the top left of the pixel to match the filled arcs drawn by
267 arc().
334b8922
TC
268 https://rt.cpan.org/Ticket/Display.html?id=101682
269
270 - enhancements to polygon filling:
271
272 - added a mode parameter to control how overlapping regions behave
273
274 - added a polypolygon() method to fill more than one polygon at a
275 time
276
277 - polygon filling is now exposed through the API.
278
45c8e262
TC
279 - added colormodel(), alphachannel() and colorchannels() methods.
280 These were added for two reasons:
281
282 - a future version of Imager may allow the number of channels in
283 an image to not directly represent the color model of an image.
284 eg. a greyscale TIFF image with multiple alpha channels.
285
286 - a future version of Imager may allow an image to be read without
287 translation, for example a TIFF file that contains measurements
0fda3cfd 288 from an instrument. Currently Imager transforms the samples into
d96c4de8 289 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
290 the value back.
291
292 An untranslated image would be unusable as image data, so
293 colormodel() would return "unknown" in this case.
294
295 Similarly a CMYK image might be returned as an "unknown" color
296 model image, if the caller chooses to disable translation to
297 RGB.

299Imager 1.001 - 2 Jan 2015
300============
301
aca60e01
TC
302 - both Imager and perl 5.21.3 define my_strerror(), prevent a conflict
303 Thanks to Slaven Rezic for the report and the patch.

327Imager 1.000 - 28 Jul 2014
328============
329
330There's nothing special about Imager 1.000, it's just another release.
331
fa3dac1d
TC
332 - fix the skip check for the iolayer qr// buffer test
333
334 - improve error reporting for the iolayer test failing on a small
335 number of Win32 CPAN testers

TC
337Imager 0.99_02 - 21 Jul 2014
338==============
339
5dab5b9a
TC
340 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
341 the blue channel in the generated palette, and allow each color
342 component to be in the range 100..255 instead of just 100..254.
343 Thanks to Ralf Neubauer.
344 https://rt.cpan.org/Ticket/Display.html?id=97086
345
346 - revert "improved the XS for i_io_read() and i_io_raw_read()"
347 This caused problems with older perls and didn't provide much of a
348 performance improvement.
349
5bf25bc2 350 - support Inline 0.57 and later.
6d47a6af 351 Inline 0.57 changed the "with" interface.

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

7b486870
TC
361 - GIF: add support for giflib 5.1.0, which added error code pointer
362 parameters to EGifCloseFile() and DGifCloseFile().
363 https://rt.cpan.org/Ticket/Display.html?id=96756
364
365 - GIF: avoid a double-free when do_write() fails.

374Imager 0.99 - 25 Jun 2014
375===========
376
dce1523b
TC
377 - Imager::IO->new_buffer() (and hence Imager->read()'s data
378 parameter) now accepts a reference to a scalar as well as just a
379 plain scalar.
6a160bce 380 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
381
382 - Imager::IO->new_buffer() now always makes a copy of the passed in
383 buffer to avoid problems with temporary objects used for the return
384 value of SvPVbyte().
6a160bce 385 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b 386

TC
387 - improved the XS for i_io_read() and i_io_raw_read()
388 https://rt.cpan.org/Ticket/Display.html?id=92738
389
390 - load plugins from absolute paths on Android
391 Thanks to Brian Fraser.
392 https://rt.cpan.org/Ticket/Display.html?id=93272
393
6a160bce
TC
394 - added the jpeg_optimize parameter for writing JPEG files. This can
395 significantly reduce file sizes, but uses more memory and time.
396 https://rt.cpan.org/Ticket/Display.html?id=94292
397
14fd9e5d
TC
398 - the autolevels filter now works on the luminosity of the image
399 rather then working per channel. The old autolevels filter is
400 still available as "autolevels_skew".
401 https://rt.cpan.org/Ticket/Display.html?id=94413
402
75d54149
TC
403 - Imager::File::PNG now supports libpng 1.6.10.
404 1.6.10 changed CRC errors from benign errors to normal errors,
405 which broke the test which used CRC errors to check for benign
406 error support. Switched to using a 1-bit grey-scale image with a
407 palette to test for benign errors.

TC
410Imager 0.98 - 3 Jan 2014
411===========
412
f84f86a2
TC
413Incompatible changes:
414
415 - the return value of setpixel() has changed.
416
417 Previously the return values for undrawable pixels vs caller errors
418 changed depending on whether you used the multiple pixel calling
419 mechanism, or the single pixel mechanism.
420
421 Now:
422
423 - for an invalid parameter, such as an unknown colour, or missing
424 parameter, an empty list (or undef in scalar context) is
425 returned, and errstr() is set,
426
427 - otherwise the number of pixels drawn is returned. If none of
428 the pixels could be drawn (they were all outside the image), "0
429 but true" is returned.
430
431 https://rt.cpan.org/Ticket/Display.html?id=87650
432
433Other changes:
434
6ba09ab9
TC
435 - when drawing on an image with an alpha channel where the source
436 minimum is greater than zero, Imager would read from beyond the end
437 of a malloc() allocated buffer. In rare circumstances this could

748 Added rounding to the linear interpolation done for rotate() and
749 matrix_transform() for 1 and 3 channel 8-bit images.
750 Adjusted the two tranlate matrices used to build the final rotation
751 matrix to use the distance between the outlier pixels rather than
752 the pixel dimensions (ie. dimension-1).
753 With all of this the output of rotate(degrees => 270) on an 8-bit
754 image exactly matches the output of rotate(right => 270).

757Other changes:

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

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

TC
787 - when downconverting samples (eg. from floating point to 8 bit)
788 Imager now rounds the sample value rather than attempting to
789 allocate input values over output values equally. The old
790 behaviour had the probably surprising effect of converting a
791 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
792 2.
793 This may result in slightly different 8 or 16-bit output images.
794

TC
795 - BI_BITFIELD BMP images were handled incorrectly, both in
796 incorrectly calculating the space required for the masks and in
797 processing the image data itself.
798 https://rt.cpan.org/Ticket/Display.html?id=76736
799
800 - some odd width BMP BI_RLE4 images use run lengths that run one off
801 the edge of the image. Imager now allows this, discarding the
802 extra column.

820 handle a statically linked libpng.
821 https://rt.cpan.org/Ticket/Display.html?id=74043
822
823 - if a probe includes testcode, Imager::Probe now checks that code as
824 part of the process of checking each configuration rather than as a
825 post test of the found configuration. This allows alternate
826 configurations to be checked if a matching but non-working
827 configuration is found.

889 - describe how to build libgif etc on OS X in such a way as to be
890 compatible with a fat binary perl (such as the system perl), in
891 README.

900 - note that the generator of the apparently non-DFSG-free postscript
901 in MMOne.pfb is a Debian package.
902
02323e69
TC
903 - setsamples() is now a true complement to getsamples() - it can
904 write 8-bit or floating point samples from a scalar or array
905 reference. This adds i_psamp() and i_psampf() to the C level API.
906
907 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
908 changed to make better use of the typemap, but these aren't part of
909 the perl level API anyway. There were no changes to the C level
910 interfaces to these functions.
911

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

936

959 identify the file type match reality.
960 https://rt.cpan.org/Ticket/Display.html?id=72475
961
962 - read() now uses $FORMATGUESS if it can't determine the file type
963 based on the file header, to match read_multi().
964
965 - re-work and add tests for def_guess_type(). def_guess_type() no

1027 engine.
1028

1048 - we rely on Config.pm's d_vsnprintf as to whether we use
1049 vsnprintf/snprintf, which is defined in the Win32 Config.pm even
1050 though it only has _ prefixed versions of these. Define our own

TC
1065 - io_glue I/O buffering re-work:
1066
1067 - reorganize io_glue to do it's own buffering by default
1068
1069 - the unbuffered functions are available as i_io_raw_read() (or
1070 raw_read() from perl) etc but are not recommended for typical
1071 use.
1072
1073 - use the new i_io_peekn() when checking for file magic to avoid
1074 seek, allowing Imager to detect the file type and read the file
1075 from an unseekable stream (for formats that don't use random
1076 access)
1077
1078 - added several new I/O layer API functions.
1079
1080 - fix the TGA performance problem, most noticably on Win32
1081 https://rt.cpan.org/Ticket/Display.html?id=70037
1082
1083 - TIFF now uses wrapper functions of the correct types to avoid casts
1084 https://rt.cpan.org/Ticket/Display.html?id=69912
1085
1086 - the callback IO object did its own buffering, controlled by the
1087 maxbuffer parameter supplied to the read() and write() methods.
1088 This buffering has been removed, to avoid redundancy with the
1089 common io_glue buffering. This also avoids a bug in that code
1090 which could rarely pass a zero length to the read callback and
1091 then panic about the result.
1092
1093 - the callback IO object now tests the result of calling the close
1094 callback, which should return true for success.
1095
1096 - the PNM reader did its own buffering. This buffering has been
1097 removed to avoid redundancy with the common io_glue buffering.
1098
1099 - previously the read handlers for fd and callback I/O layers would
1100 call the underlying interface (POSIX read or your supplied callback)
1101 until it filled the buffer. It now only makes one call.
1102
1103 - added public constructors for I/O layer objects (see Imager::IO)
1104
1105 - all core file handlers now use the i_io_foo() wrappers to gain
1106 access to buffered I/O rather than calling the I/O layer
1107 callbacks directly.
1108
1109 - all core file handlers now check for error on close.
1110
1111 - Backward compatibility: if you hava custom file handlers, you can
1112 use i_io_write() etc since they're available as macros in older
1113 versions of Imager.
1114
1115 - eliminate the final remnants of io_glue_commit_types().
1116
1117 - bump IMAGER_API_VERSION, since the above may break assumptions.
1118
1119 - removed the long unused i_gen_reader() and i_gen_writer() utility
1120 functions.

1125The main changes in the release versus 0.84 are:
1126
1127 - on 64-bit systems, 64-bit types are consistently used for image
1128 dimensions and co-ordinated, and for memory block sizes.
1129
1130 - handle IFD loops in TIFF files correctly. Previously this would
1131 lead to an infinite loop.

1183Development release as a sanity check for the types re-work.
8d14daab
TC
1184
1185Massive types re-work:
1186
1187 - the type used internally for pixel co-ordinates and image sizes is
1188 now 64-bit on 64-bit platforms (at least sane ones).
1189
1190 - size_t is now used consistently for memory block sizes.
1191
1192 - since this changes the binary interface, the Imager API version has
1193 been incremented. Any module that uses the API will need to be
1194 rebuilt. In most cases that will be enough, but calls to any APIs
1195 that take a pointer to image sizes may need source changes.
1196
1197 - you should be able to create very large images on 64-bit systems,
1198 if you have enough memory. Successfully created a 32768 x 49192 x
1199 3 channel image, filled with a tiled image and scaled it. The
1200 unscaled image was also successfully saved to a JPEG.
1201
1202 - check the image size before attempting to write BMP, GIF, JPEG,
1203 PNG, SGI, TGA, TIFF images.
1204
1205 - correctly handle reading TGA images over 32767 pixels wide or tall.
1206
1207Incidental changes:
1208
1209 - the gif_left and gif_top tags are now clamped to non-negative
1210 values when writing a GIF image.
1211
1212 - removed dead callback read/write code
1213
1214The default maximum memory size when reading files is now 1G.

1834 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1835 resulting in a SIGSEGV when attempting to scale an image to a size
1836 too large to fit in memory. This is a NULL pointer access issue,
1837 not a buffer overflow.

1852This release primarily contains changes to improve ease of use -
1853rather than you having to convert images to the appropriate number of
1854channels, Imager handles it internally. How to handle drawing colors
1855and the default combine mode is a thornier problem left for some other
1856release.

TC
1861 - moved the imtoc.perl code into Imager::Preprocess
1862
1863 - paste() and rubthrough() now adapt the source image data to the
1864 destination, so you can now safely paste/rubthrough from greyscale
1865 images to color images or back, or from alpha channel images to
1866 noalpha channels or back.
1867 https://rt.cpan.org/Ticket/Display.html?id=30908
1868
1869 - rubthrough() now falls back to pasting when the source doesn't have
1870 an alpha channel. This effectively treats the source as having a
1871 max alpha channel, the right thing to do.
1872 http://rt.cpan.org/Ticket/Display.html?id=29944
1873
1874 - re-worked most of the area filling code to use a common set of
1875 functions when filling.
1876 Corrected normal combine mode.
1877 Rewrote most of the combine modes to match the way the SVG draft
1878 defines them with respect to a translucent source and destination.
1879 Added tests for translucent source and destination.
1880 Added tests to check 8-bit/sample and double/sample combines work
1881 similarly.

1919
1920 - handling of the left-over bit for 16-bit/pixel TGA images has been
1921 changed to match the behaviour of the GIMP. Previously the bit
1922 being set was treated as an opaque pixel, but one user reported a
1923 problem with loading such an image. I haven't been able to find any
1924 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1925 I'll match it's behaviour. See issue 114913 in the GIMP's
1926 bugzilla.

1936 - the old dynaload code used Mach API functions to load dynamic
1937 libraries on Mac OS X. These APIs have been deprecated in OS X
1938 10.5 and were causing some build problems.

1940 will need version 10.3 or later of OS X.

2172 - reworked library probing, we can now set more than one probe
2173 function for a library. Disabled the default (non-freetype-config)
2174 library probe and added an extra probe function that searches for
2175 both ft2build.h and whatever it includes, and adds -I as needed.
2176 Hopefully this will fix build problems like

2244Imager 0.55 - 16 Dec 2006
2245===========
2246
2247This is primarily a bug fix release.
2248
2249Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2250
2251There is one new feature:
2252
2253 - the Win32 font driver now supports UTF8 (RT 22166)
2254 http://www.cpanforum.com/threads/3276
2255 http://rt.cpan.org/Ticket/Display.html?id=22166
2256
2257Several bugs were fixed:
2258
2259 - the string() method would not output the string "0"
2260 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2261
2262 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2263 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2264
2265 - the gif_disposal and gif_user_input tags weren't being read from
2266 the file correctly
2267 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2268
2269 - gif.c was failing to build under MSVC
2270 http://rt.cpan.org/Ticket/Display.html?id=23922
2271
2272 - in some cases strings passed to the string() method were treated as
2273 terminated by NUL (chr 0)
2274 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2275
2276 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2277 that's the default build name for zlib on Win32.
2278 http://rt.cpan.org/Ticket/Display.html?id=23064
2279
2280 - search $Config{incpath} for headers too, which we should have been
2281 doing all along.
2282
2283Win32 font driver fixes:
2284
2285 - the global descent value from bounding box was the wrong sign
2286 http://www.cpanforum.com/threads/3276
2287
2288 - if the first or last glyph overflowed the left or right side of the
2289 advance width they would be clipped
2290
2291
2292Imager 0.54 - 14 Sep 2006
2293===========
2294
2295This is primarily a feature release:
2296
2297 - a new qtype value 'mixing' has been added to the scale()
2298 method. This is faster than 'normal', slower than 'preview'. This
2299 is based on the method used by pnmscale, and seems to produce less
2300 blurry results than normal.
2301 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2302
2303 - the rubthrough() method can now render onto images with an alpha
2304 channel.
2305 http://rt.cpan.org/Ticket/Display.html?id=20678
2306
2307 - the read_multi() method now falls back to calling doing a single
2308 image read via the read() method and write_multi() will now fall
2309 back to calling write() if a single image is supplied. This means
2310 you can simply call the read_multi() or write_multi() functions
2311 without having to check if the type is formatted by that method.
2312 http://rt.cpan.org/Ticket/Display.html?id=19457
2313 http://rt.cpan.org/Ticket/Display.html?id=19458
2314
2315 - the GIF loop extension can now be written. If you don't have
2316 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2317 should upgrade.
2318 http://rt.cpan.org/Ticket/Display.html?id=21185
2319
2320 - getscanline() and setscanline() can now read/write palette index
2321 based data from/to the image for paletted images, by setting type to
2322 'index'.
2323 http://rt.cpan.org/Ticket/Display.html?id=20338
2324
2325 - we no longer hassle you to disable GIF support
2326 http://rt.cpan.org/Ticket/Display.html?id=20687
2327
2328 - minor documentation fixes
2329
2330
2331Imager 0.53 - 26 Jul 2006
2332===========
2333
2334This is a bugfix release.
2335
2336Some test code was left in a code path not covered by the test
2337suite. A test was added to cover this code path and the test code was
2338removed.
2339http://rt.cpan.org/Public/Bug/Display.html?id=20705
2340
2341
2342Imager 0.52 - 25 Jul 2006
2343===========
2344
2345This is primarily a feature release, but contains a fair few bug
2346fixes, new features:
2347
2348 - ability to read and write MS Windows ICO and CUR files
2349
2350 - you can now add file format plugins to support new file formats
2351
2352 - add POD coverage tests
2353
2354 - setcolors() and addcolors() now accept color names and so on
2355 instead of requiring Imager::Color objects.
2356 http://rt.cpan.org/Ticket/Display.html?id=20056
2357
2358 - flood_fill() can now fill to a specified border color instead of
2359 just to the area the same color as the seed.
2360 http://rt.cpan.org/Ticket/Display.html?id=19618
2361
2362
2363Bug fixes:
2364
2365 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2366 calculating the advance width.
2367 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2368
2369 - bounding_box for the T1 driver wasn't including leading and
2370 trailing spaces in the bounding box as the other drivers did, it also
2371 produced strange results for empty strings or strings containing only
2372 spaces
2373
2374 - when reading CMYK jpeg images they were being transferred to the
2375 image object as is, producing a four channel image. It only looked ok
2376 due to an old still unfixed Photoshop bug. We now convert from the
2377 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2378 http://rt.cpan.org/Ticket/Display.html?id=20416
2379
2380 - reading a CYMK TIFF would result in a 4 channel image, reading any
2381 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2382 result in an error.
2383 http://rt.cpan.org/Ticket/Display.html?id=20415
2384
2385 - added /usr/local/include to the default include search path, since
2386 we were already searching /usr/local/lib for libraries.
2387
2388And various minor fixes and documentation updates.
2389
2390
2391Imager 0.51 - 23 Apr 2006

2395 a crash
2396 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2397
2398 - fix mis-processing of the src_maxx and src_maxy parameters of the
2399 paste() method
2400 http://rt.cpan.org/Public/Bug/Display.html?id=18712

2411 or 4 channel image to jpeg or a 2 channel image to tga where the
2412 output is an in-memeory buffer.
2413 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2414
2415 - fixes an incorrect pointer parameter in the PNG code
2416 http://rt.cpan.org/Public/Bug/Display.html?id=18051
