3Coverity finally finished a build, fix a few problems:
4
5 - reading a color-mapped TGA file with an id string would cause a
6 double-free if the palette was truncated.
7
6494c395
TC
8 - mixing scaling to sizes where the accumulator row, the working
9 output row or the working input row didn't fit into the address
10 space could result in memory leaks. This can probably only be
11 reproduced on very wide floating-point sample images.
12
fc24ca5f 13 - convert an array style function parameter pointer to pointer style
3d7b055c
TC
14 to prevent confusing Coverity in the T1 bounding box implementation.
15
16 - Similarly in the FT1 bounding box implementation.
fc24ca5f
TC
17
18 - initialize a pointer to prevent Coverity complaining in polygon
19 drawing (it should always end up being set.)

25============
26
75e155e1 27 - moved EXIF handling from Imager::File::JPEG to core Imager
b5bbf161
TC
28 This allows file formats that store EXIF data as blobs similarly
29 to JPEG to re-use this code. (such as Imager::File::WEBP)
75e155e1 30

52 - the internal i_errors() function now correctly allocates the stack
53 space needed for its result.
54 https://rt.perl.org/rt3/Ticket/Display.html?id=131938
55
56 - t/100-base/020-color.t now uses Imager::Test's test functions
57 instead of its own.

60 - write_multi() now returns an error result (a false value) if called
61 with a non-(Imager image object). Previously it would typically
62 crash.

64
65 - improve the documentation of the jpegquality parameter when
66 writing JPEG files.

TC
100 - don't use the seek() method on opened() handles in
101 t/200-file/400-basic.t. In older versions of perl such handles are
102 only IO::Handle objects, not IO::File, and don't have a seek()
103 method.

105Imager 1.004_001 - 16 Mar 2016 (Birthday release - but not my birthday)
106================
107
08914ed1
TC
108 - re-work the t/200-file/400-basic.t to correctly handle failures
109 It's custom ok() function didn't have a prototype and didn't use scalar().
110 This caused ok() to use the note instead of the value being tested when
111 the method called returned an empty list. For an example of the problem
e6226ce5 112 caused see: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=812093
08914ed1 113
a2791e47
TC
114 - remove some noise from when Imager tried to work with bugs in old
115 versions of giflib. I can't do much about the new bugs.
08914ed1 116
e6226ce5
TC
117 - the new autolevels filter (Imager 0.99) used an integer for the
118 sample scaling factor which caused the top output level to be too
119 low (depending on the scaling required.) It now uses a double.
08914ed1
TC
120 https://rt.cpan.org/Ticket/Display.html?id=111871
121
e6226ce5 122 - the new autolevels filter had off-by-one errors calculating the
08914ed1
TC
123 minimum and maximum luminance from the histogram. This slightly
124 reduced the contrast of the output image.
125 https://rt.cpan.org/Ticket/Display.html?id=111871
126
127 - the new autolevels filter now uses a lookup table for 8-bit images
128 to avoid a floating point multiply for each sample.
129 https://rt.cpan.org/Ticket/Display.html?id=111871
130
e6226ce5
TC
131 - fixed several memory leaks detected by valgrind:
132
133 - addcolors() leaked the temporary array of colors supplied to the
134 internal API
135
136 - make_palette() leaked the temporary image array (not the images
137 themselves) passed to the internal API.
138
139 - combine()/i_combine() leaked its working row buffers
140
141 - getcolorusage()/i_get_anonymous_color_histo() leaked the sample
142 buffer if there were too many colors
143
144 - getcolorcount()/i_count_colors() leaked the sample buffer if
145 there were too many colors.
146
147 - the nearest_color filter (undocumented until I find a use for it)
148 leaked both temporaries passed to the API and internal buffers
149
a2791e47
TC
150 - the internal process of upgrading a paletted image to a direct
151 color image would leak a context object reference count.
152
153 - a write failure when writing to a GIF file could leak memory.
154
155 - failing to write to a 1-bit/pixel ICO image could leak memory.
156
157 - Imager no longer deliberately leaks the context object from the
158 initial thread. This was done to ensure there was always a context
159 object available, but the code that needed that now handles the
160 lack correctly,
161
e6226ce5
TC
162 - fixed some uninitialized memory usage detected by valgrind:
163
164 - rotate()/i_rotate_exact()/i_rotate_exact_bg()/i_matrix_transform()/
165 i_matrix_transform_bg() didn't initialize a working color value
166 if there was zero pixel coverage.
167
168 - i_ft2_cp() didn't initialize the complete color when producing an
169 intermediate image. This caused uninitialized value usage when
170 logging the color.

0fda3cfd
TC
191 - update 1.002 release notes to include the center change for filled
192 circle drawing.
193
194 - flood_fill() would escape beyond a 4-connected space under some
195 circumstances.
196 Added many more flood_fill() tests.

TC
199Imager 1.002 - 3 Apr 2015
200============
201
334b8922
TC
202 - drawing anti-aliased filled circles is now 10 to 50 times faster
203 depending on the size of the circle.
0fda3cfd
TC
204 This also changed the center from being the center of the pixel to
205 being the top left of the pixel to match the filled arcs drawn by
206 arc().
334b8922
TC
207 https://rt.cpan.org/Ticket/Display.html?id=101682
208
209 - enhancements to polygon filling:
210
211 - added a mode parameter to control how overlapping regions behave
212
213 - added a polypolygon() method to fill more than one polygon at a
214 time
215
216 - polygon filling is now exposed through the API.
217
45c8e262
TC
218 - added colormodel(), alphachannel() and colorchannels() methods.
219 These were added for two reasons:
220
221 - a future version of Imager may allow the number of channels in
222 an image to not directly represent the color model of an image.
223 eg. a greyscale TIFF image with multiple alpha channels.
224
225 - a future version of Imager may allow an image to be read without
226 translation, for example a TIFF file that contains measurements
0fda3cfd 227 from an instrument. Currently Imager transforms the samples into
d96c4de8 228 the range 0.0 ... 1.0 which may means the user has to translate
45c8e262
TC
229 the value back.
230
231 An untranslated image would be unusable as image data, so
232 colormodel() would return "unknown" in this case.
233
234 Similarly a CMYK image might be returned as an "unknown" color
235 model image, if the caller chooses to disable translation to
236 RGB.

TC
279 - Imager::Filter::Mandelbrot (and dynfilt/mandelbrot.c) - initialize
280 the blue channel in the generated palette, and allow each color
281 component to be in the range 100..255 instead of just 100..254.
282 Thanks to Ralf Neubauer.
283 https://rt.cpan.org/Ticket/Display.html?id=97086
284
285 - revert "improved the XS for i_io_read() and i_io_raw_read()"
286 This caused problems with older perls and didn't provide much of a
287 performance improvement.
288
5bf25bc2 289 - support Inline 0.57 and later.
6d47a6af 290 Inline 0.57 changed the "with" interface.

314===========
315
dce1523b
TC
316 - Imager::IO->new_buffer() (and hence Imager->read()'s data
317 parameter) now accepts a reference to a scalar as well as just a
318 plain scalar.
6a160bce 319 https://rt.cpan.org/Ticket/Display.html?id=92785
dce1523b
TC
320
321 - Imager::IO->new_buffer() now always makes a copy of the passed in
322 buffer to avoid problems with temporary objects used for the return
323 value of SvPVbyte().

330 Thanks to Brian Fraser.
331 https://rt.cpan.org/Ticket/Display.html?id=93272
332
6a160bce
TC
333 - added the jpeg_optimize parameter for writing JPEG files. This can
334 significantly reduce file sizes, but uses more memory and time.
335 https://rt.cpan.org/Ticket/Display.html?id=94292
336
14fd9e5d
TC
337 - the autolevels filter now works on the luminosity of the image
338 rather then working per channel. The old autolevels filter is
339 still available as "autolevels_skew".
340 https://rt.cpan.org/Ticket/Display.html?id=94413
341
75d54149
TC
342 - Imager::File::PNG now supports libpng 1.6.10.
343 1.6.10 changed CRC errors from benign errors to normal errors,
344 which broke the test which used CRC errors to check for benign
345 error support. Switched to using a 1-bit grey-scale image with a
346 palette to test for benign errors.

349Imager 0.98 - 3 Jan 2014
350===========
351
f84f86a2
TC
352Incompatible changes:
353
354 - the return value of setpixel() has changed.
355
356 Previously the return values for undrawable pixels vs caller errors
357 changed depending on whether you used the multiple pixel calling
358 mechanism, or the single pixel mechanism.
359
360 Now:
361
362 - for an invalid parameter, such as an unknown colour, or missing
363 parameter, an empty list (or undef in scalar context) is
364 returned, and errstr() is set,
365
366 - otherwise the number of pixels drawn is returned. If none of
367 the pixels could be drawn (they were all outside the image), "0
368 but true" is returned.
369
370 https://rt.cpan.org/Ticket/Display.html?id=87650
371
372Other changes:
373
6ba09ab9
TC
374 - when drawing on an image with an alpha channel where the source
375 minimum is greater than zero, Imager would read from beyond the end
376 of a malloc() allocated buffer. In rare circumstances this could
377 lead to some of the source image not being written to the target
378 image, or possibly to a segmentation fault.
379 I don't believe this has any security concerns beyond that.
380
0d052fd9
TC
381 - if the first text drawn with Imager::Font::T1 is not anti-aliased,
382 text drawn would be nonsense. This would also read beyond the end
383 of a malloced buffer.
384
13671b17
TC
385 - non-AA text drawn with an Imager::Font::TT (Truetype 1) font would be
386 truncated early.

388

TC
396 - Image::Probe, Imager's internal module for probing library
397 locations now searches the directories specified by LD_RUN_PATH,
398 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH and LIBRARY_PATH for libraries,
399 and the corresponing s/\blib$/include/ directories for header
400 files.

429
430 Handle SampleFormat = 3 where possible.
431
432 SampleFormat is ignored for paletted images.
433
237d9e03
TC
434 Mixed SampleFormat are handled incorrectly, since libtiff returns
435 only the first SampleFormat value, and an image with both an alpha
436 channel and SampleFormat = 2 for color channels probably has a
437 different SampleFormat for the alpha channel.

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

695
ef84bb32
TC
696Other changes:
697
698 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
699 internals, those names only matter for the XS interface.
700
701 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
702 the API level compiled into a loadable module such as
703 Imager::File::GIF doesn't match that of Imager. Previously it
704 could be difficult to determine exactly which module was failing to
705 load.
706 https://rt.cpan.org/Ticket/Display.html?id=77173
707
708 - added Imager->check_file_limits() as an interface to the
709 i_int_check_image_file_limits() API.
710
711 - Imager->set_file_limits(reset => 1) now resets the limits to the
712 defaults rather than setting them all to unlimited.

725
29b38678
TC
726 - when downconverting samples (eg. from floating point to 8 bit)
727 Imager now rounds the sample value rather than attempting to
728 allocate input values over output values equally. The old
729 behaviour had the probably surprising effect of converting a
730 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
731 2.
732 This may result in slightly different 8 or 16-bit output images.
733
e2a86bac
TC
734 - BI_BITFIELD BMP images were handled incorrectly, both in
735 incorrectly calculating the space required for the masks and in
736 processing the image data itself.
737 https://rt.cpan.org/Ticket/Display.html?id=76736
738
739 - some odd width BMP BI_RLE4 images use run lengths that run one off
740 the edge of the image. Imager now allows this, discarding the
741 extra column.
742
743 - odd length RLE4 runs in BMP images were decoded incorrectly.
744

TC
745 - pkg-config could sometimes return a library that was in a directory
746 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
747 If no -L is included in the pkg-config library information check if
748 EU::MM can find the library, and if not, search our configured
749 directories and insert that into the library flags.

752 - Imager::Probe can now probe for libraries with dependent libraries,
753 common for static linking, eg. libpng requires libz.
754 https://rt.cpan.org/Ticket/Display.html?id=74043
755
756 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
757
758 - added alternative probe configurations that try to link libz, to
759 handle a statically linked libpng.
760 https://rt.cpan.org/Ticket/Display.html?id=74043
761
762 - if a probe includes testcode, Imager::Probe now checks that code as
763 part of the process of checking each configuration rather than as a
764 post test of the found configuration. This allows alternate
765 configurations to be checked if a matching but non-working
766 configuration is found.

845
846 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have

1002 - add simple tests for the Imager::Test test_image generators

TC
1004 - io_glue I/O buffering re-work:
1005
1006 - reorganize io_glue to do it's own buffering by default
1007
1008 - the unbuffered functions are available as i_io_raw_read() (or
1009 raw_read() from perl) etc but are not recommended for typical
1010 use.
1011
1012 - use the new i_io_peekn() when checking for file magic to avoid
1013 seek, allowing Imager to detect the file type and read the file
1014 from an unseekable stream (for formats that don't use random
1015 access)
1016
1017 - added several new I/O layer API functions.
1018
1019 - fix the TGA performance problem, most noticably on Win32
1020 https://rt.cpan.org/Ticket/Display.html?id=70037
1021
1022 - TIFF now uses wrapper functions of the correct types to avoid casts
1023 https://rt.cpan.org/Ticket/Display.html?id=69912
1024
1025 - the callback IO object did its own buffering, controlled by the
1026 maxbuffer parameter supplied to the read() and write() methods.
1027 This buffering has been removed, to avoid redundancy with the
1028 common io_glue buffering. This also avoids a bug in that code
1029 which could rarely pass a zero length to the read callback and
1030 then panic about the result.
1031
1032 - the callback IO object now tests the result of calling the close
1033 callback, which should return true for success.
1034
1035 - the PNM reader did its own buffering. This buffering has been
1036 removed to avoid redundancy with the common io_glue buffering.
1037
1038 - previously the read handlers for fd and callback I/O layers would
1039 call the underlying interface (POSIX read or your supplied callback)
1040 until it filled the buffer. It now only makes one call.
1041
1042 - added public constructors for I/O layer objects (see Imager::IO)
1043
1044 - all core file handlers now use the i_io_foo() wrappers to gain
1045 access to buffered I/O rather than calling the I/O layer
1046 callbacks directly.
1047
1048 - all core file handlers now check for error on close.
1049
1050 - Backward compatibility: if you hava custom file handlers, you can
1051 use i_io_write() etc since they're available as macros in older
1052 versions of Imager.
1053
1054 - eliminate the final remnants of io_glue_commit_types().
1055
1056 - bump IMAGER_API_VERSION, since the above may break assumptions.
1057
1058 - removed the long unused i_gen_reader() and i_gen_writer() utility
1059 functions.

1121
1122Development release as a sanity check for the types re-work.
8d14daab
TC
1123
1124Massive types re-work:
1125
1126 - the type used internally for pixel co-ordinates and image sizes is
1127 now 64-bit on 64-bit platforms (at least sane ones).
1128
1129 - size_t is now used consistently for memory block sizes.
1130
1131 - since this changes the binary interface, the Imager API version has
1132 been incremented. Any module that uses the API will need to be
1133 rebuilt. In most cases that will be enough, but calls to any APIs
1134 that take a pointer to image sizes may need source changes.
1135
1136 - you should be able to create very large images on 64-bit systems,
1137 if you have enough memory. Successfully created a 32768 x 49192 x
1138 3 channel image, filled with a tiled image and scaled it. The
1139 unscaled image was also successfully saved to a JPEG.
1140
1141 - check the image size before attempting to write BMP, GIF, JPEG,
1142 PNG, SGI, TGA, TIFF images.
1143
1144 - correctly handle reading TGA images over 32767 pixels wide or tall.
1145
1146Incidental changes:
1147
1148 - the gif_left and gif_top tags are now clamped to non-negative
1149 values when writing a GIF image.
1150
1151 - removed dead callback read/write code
1152
1153The default maximum memory size when reading files is now 1G.

1769 - check that the result of fileno($fh) is defined rather than simply
1770 true when read() or write() is supplied with an fh parameter.

1773 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1774 resulting in a SIGSEGV when attempting to scale an image to a size
1775 too large to fit in memory. This is a NULL pointer access issue,
1776 not a buffer overflow.
1777 Added a check for the failure.
1778 scale_calculate() (and hence scale()) will now fail if any of the
1779 scale size parameters are a reference.

1791This release primarily contains changes to improve ease of use -
1792rather than you having to convert images to the appropriate number of
1793channels, Imager handles it internally. How to handle drawing colors
1794and the default combine mode is a thornier problem left for some other
1795release.

1800 - moved the imtoc.perl code into Imager::Preprocess
1801
1802 - paste() and rubthrough() now adapt the source image data to the
1803 destination, so you can now safely paste/rubthrough from greyscale
1804 images to color images or back, or from alpha channel images to
1805 noalpha channels or back.
1806 https://rt.cpan.org/Ticket/Display.html?id=30908
1807
1808 - rubthrough() now falls back to pasting when the source doesn't have
1809 an alpha channel. This effectively treats the source as having a
1810 max alpha channel, the right thing to do.
1811 http://rt.cpan.org/Ticket/Display.html?id=29944
1812
1813 - re-worked most of the area filling code to use a common set of
1814 functions when filling.
1815 Corrected normal combine mode.
1816 Rewrote most of the combine modes to match the way the SVG draft
1817 defines them with respect to a translucent source and destination.
1818 Added tests for translucent source and destination.
1819 Added tests to check 8-bit/sample and double/sample combines work
1820 similarly.

1856 - some TGA images weren't being detected correctly as TGA images
1857 https://rt.cpan.org/Ticket/Display.html?id=32925
1858
1859 - handling of the left-over bit for 16-bit/pixel TGA images has been
1860 changed to match the behaviour of the GIMP. Previously the bit
1861 being set was treated as an opaque pixel, but one user reported a
1862 problem with loading such an image. I haven't been able to find any
1863 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1864 I'll match it's behaviour. See issue 114913 in the GIMP's
1865 bugzilla.

1875 - the old dynaload code used Mach API functions to load dynamic
1876 libraries on Mac OS X. These APIs have been deprecated in OS X
1877 10.5 and were causing some build problems.

1879 will need version 10.3 or later of OS X.

2178 https://rt.cpan.org/Ticket/Display.html?id=25561
2179
2180 - avoid Data::Dumper in regops.perl to support older releases of perl

2183Imager 0.55 - 16 Dec 2006
2184===========
2185
2186This is primarily a bug fix release.
2187
2188Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
2189
2190There is one new feature:
2191
2192 - the Win32 font driver now supports UTF8 (RT 22166)
2193 http://www.cpanforum.com/threads/3276
2194 http://rt.cpan.org/Ticket/Display.html?id=22166
2195
2196Several bugs were fixed:
2197
2198 - the string() method would not output the string "0"
2199 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2200
2201 - fills.c was failing to compile on Solaris 10 (compiler unknown)
2202 http://rt.cpan.org/Public/Bug/Display.html?id=21944
2203
2204 - the gif_disposal and gif_user_input tags weren't being read from
2205 the file correctly
2206 http://rt.cpan.org/Public/Bug/Display.html?id=22192
2207
2208 - gif.c was failing to build under MSVC
2209 http://rt.cpan.org/Ticket/Display.html?id=23922
2210
2211 - in some cases strings passed to the string() method were treated as
2212 terminated by NUL (chr 0)
2213 http://rt.cpan.org/Public/Bug/Display.html?id=21770
2214
2215 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
2216 that's the default build name for zlib on Win32.
2217 http://rt.cpan.org/Ticket/Display.html?id=23064
2218
2219 - search $Config{incpath} for headers too, which we should have been
2220 doing all along.
2221
2222Win32 font driver fixes:
2223
2224 - the global descent value from bounding box was the wrong sign
2225 http://www.cpanforum.com/threads/3276
2226
2227 - if the first or last glyph overflowed the left or right side of the
2228 advance width they would be clipped
2229
2230
2231Imager 0.54 - 14 Sep 2006
2232===========
2233
2234This is primarily a feature release:
2235
2236 - a new qtype value 'mixing' has been added to the scale()
2237 method. This is faster than 'normal', slower than 'preview'. This
2238 is based on the method used by pnmscale, and seems to produce less
2239 blurry results than normal.
2240 http://rt.cpan.org/Public/Bug/Display.html?id=20677
2241
2242 - the rubthrough() method can now render onto images with an alpha
2243 channel.
2244 http://rt.cpan.org/Ticket/Display.html?id=20678
2245
2246 - the read_multi() method now falls back to calling doing a single
2247 image read via the read() method and write_multi() will now fall
2248 back to calling write() if a single image is supplied. This means
2249 you can simply call the read_multi() or write_multi() functions
2250 without having to check if the type is formatted by that method.
2251 http://rt.cpan.org/Ticket/Display.html?id=19457
2252 http://rt.cpan.org/Ticket/Display.html?id=19458
2253
2254 - the GIF loop extension can now be written. If you don't have
2255 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
2256 should upgrade.
2257 http://rt.cpan.org/Ticket/Display.html?id=21185
2258
2259 - getscanline() and setscanline() can now read/write palette index
2260 based data from/to the image for paletted images, by setting type to
2261 'index'.
2262 http://rt.cpan.org/Ticket/Display.html?id=20338
2263
2264 - we no longer hassle you to disable GIF support
2265 http://rt.cpan.org/Ticket/Display.html?id=20687
2266
2267 - minor documentation fixes
2268
2269
2270Imager 0.53 - 26 Jul 2006
2271===========
2272
2273This is a bugfix release.
2274
2275Some test code was left in a code path not covered by the test
2276suite. A test was added to cover this code path and the test code was
2277removed.
2278http://rt.cpan.org/Public/Bug/Display.html?id=20705
2279
2280
2281Imager 0.52 - 25 Jul 2006
2282===========
2283
2284This is primarily a feature release, but contains a fair few bug
2285fixes, new features:
2286
2287 - ability to read and write MS Windows ICO and CUR files
2288
2289 - you can now add file format plugins to support new file formats
2290
2291 - add POD coverage tests
2292
2293 - setcolors() and addcolors() now accept color names and so on
2294 instead of requiring Imager::Color objects.
2295 http://rt.cpan.org/Ticket/Display.html?id=20056
2296
2297 - flood_fill() can now fill to a specified border color instead of
2298 just to the area the same color as the seed.
2299 http://rt.cpan.org/Ticket/Display.html?id=19618
2300
2301
2302Bug fixes:
2303
2304 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
2305 calculating the advance width.
2306 http://rt.cpan.org/Public/Bug/Display.html?id=20554
2307
2308 - bounding_box for the T1 driver wasn't including leading and
2309 trailing spaces in the bounding box as the other drivers did, it also
2310 produced strange results for empty strings or strings containing only
2311 spaces
2312
2313 - when reading CMYK jpeg images they were being transferred to the
2314 image object as is, producing a four channel image. It only looked ok
2315 due to an old still unfixed Photoshop bug. We now convert from the
2316 inverted CMYK that photoshop (and Corel for example) produce into RGB.
2317 http://rt.cpan.org/Ticket/Display.html?id=20416
2318
2319 - reading a CYMK TIFF would result in a 4 channel image, reading any
2320 image with more than 4 channels (eg. RGB with 2 alpha channels) would
2321 result in an error.
2322 http://rt.cpan.org/Ticket/Display.html?id=20415
2323
2324 - added /usr/local/include to the default include search path, since
2325 we were already searching /usr/local/lib for libraries.
2326
2327And various minor fixes and documentation updates.
2328
2329

2334 a crash
2335 http://rt.cpan.org/Public/Bug/Display.html?id=18496
2336
2337 - fix mis-processing of the src_maxx and src_maxy parameters of the
2338 paste() method
2339 http://rt.cpan.org/Public/Bug/Display.html?id=18712

2344
2345

2347===========
2348

2350 or 4 channel image to jpeg or a 2 channel image to tga where the
2351 output is an in-memeory buffer.
2352 http://rt.cpan.org/Public/Bug/Display.html?id=18397
2353
2354 - fixes an incorrect pointer parameter in the PNG code
2355 http://rt.cpan.org/Public/Bug/Display.html?id=18051
