TC
13 - TIFF: handle SampleFormat = 2 by translating the signed integer
14 values to unsigned by flipping their sign bits.
15
16 Handle SampleFormat = 3 where possible.
17
18 SampleFormat is ignored for paletted images.
19
237d9e03
TC
20 Mixed SampleFormat are handled incorrectly, since libtiff returns
21 only the first SampleFormat value, and an image with both an alpha
22 channel and SampleFormat = 2 for color channels probably has a
23 different SampleFormat for the alpha channel.

face45e7 29
237d9e03 30 - Imager::Color's rgba() method now returns its values as integers
face45e7

TC
33 - The XS for i_map() and i_matrix_transform() now use the AV *
34 typemap instead of rolling their own.
35

TC
36 - The XS for DSO_call() now uses the HV * typemap instead of
37 rolling it's own.
38
0aaa8b4d
TC
39 - The XS for i_poly_aa(), i_poly_aa_cfill(), i_transform() and
40 i_gradgen() now use a new T_AVARRAY typemap that greatly
41 simplifies the XS code.

TC
67 - rearrange Imager's test files.
68 https://rt.cpan.org/Ticket/Display.html?id=84596
69
70 - Imager::Probe::_gcc_lib_paths now forces C locale.
71 A sufficiently recent gcc prints localized keys for the search
72 paths, which avoids that localization.
73 https://rt.cpan.org/Ticket/Display.html?id=84963
74
75 - fix a pod error detected by Pod::Simple 3.27 and laterm and skip
76 pod tests unless AUTOMATED_TESTING or IMAGER_AUTHOR_TESTING is set
77 and true.

94Imager 0.95 - 19 Apr 2013
95===========
96
0a2956ab
TC
97 - handle the SVf_UTF8 flag correctly on magic strings passed to
98 Imager::IO's write() and raw_write() methods.
99 This may misbehave in perl 5.6.x since the UTF8 flag may not be
100 visible in the main SV after SvGETMAGIC().
101 https://rt.cpan.org/Ticket/Display.html?id=83438
102
103 - document that bounding_box() ignores the transformation matrix
104 supplied to tranform() for fonts.

108==============
109
1540d1d4
TC
110 - enable debug logging for the standard font tests
111
112 - skip the overloaded UTF-8 text output checks on 5.6.x and earlier,
113 due to a bug in that version of perl.
114
115 - don't test for read() failing on a write-only handle in 5.8.x and
116 earlier, this was fixed in change 862083f7e4 in perl.
117
118 - report the version of Inline found during testing (an attempt to
119 diagnose some intermittent failures.)

121Imager 0.94_01 - 2 Mar 2013
122==============
123
14a4ea18 124 - NOTE: possibly backward incompatible:
3dcf7595
TC
125 support reading from/writing to perl filehandes that aren't raw
126 files.
127
128 This allows Imager's I/O to honour handles with layers such as
129 gzip, scalar file handles or tied file handles.
130
14a4ea18 131 This is backward incompatible in that previous Imager would simply
3dcf7595
TC
132 use fileno() to retrieve the fd for the file and call write(2) etc
133 on it directly.
04d8c568
TC
134 https://rt.cpan.org/Ticket/Display.html?id=78843
135
136 - moved most of README to lib/Imager/Install.pod which should make it
137 more accessible to the "web" generation, also significantly updated
138 and re-worked it.
3dcf7595 139
ca96f811
TC
140 - updated README's for the separately distributed modules to refer to
141 Imager::Install, and that they need -dev versions of packages
142 https://rt.cpan.org/Ticket/Display.html?id=81265
143
26e8a226
TC
144 - the JPEG test code now reports the compile-time library version
145

TC
156 - drawing text to a channel with FT2 would draw with random coverage
157 due to an uninitialized alpha channel.
158
159 - marked the function pointer underlying the mm_log() API with the
160 correct gcc magic and fixed the resulting warnings.
161
162 - fixed some other compiler warnings
163
14a4ea18
TC
164 - Imager::Font::W32 now properly reports text drawing errors

14a4ea18
TC
168 strings passed as text to draw(), bounding_box(), has_chars(),
169 glyph_names() (where supported) in each of the font drivers.
0a2956ab
TC
170 This may misbehave in perl 5.6.x since the UTF8 flag may not be
171 visible in the main SV after SvGETMAGIC().

175=========================
176
177Variations on some of these changes were included in development
178releases.
179
4be61824
TC
180 - improved thread safety
181 - the internal error stack and log file handle are now in a per-thread
182 context object
183 - JPEG now captures IPTC information in a thread-safe way
184 - avoid globals where possible for warning capture in libtiff
244725cf
TC
185 - use a mutex to avoid re-entering thread-unsafe giflib
186 - use a mutex to avoid re-entering thread-unsafe tifflib
187 - use a mutex to avoid re-entering thread-unsafe T1Lib
188 - use a library handle per thread for freetype 2.
0124c060 189 - use an engine handle per thread for freetype 1.x.
0eebfd59

204Imager 0.93 - 15 Oct 2012
205===========
206
207Bug fixes:
71fbe41a
TC
208
209 - previously a transparency enabled GIF write (the default) would
210 always use a GIF89a header even if none of the images were
211 transparent.
7a5f7bc6 212
b2f967ef
TC
213 - previously the probe step for freetype-config would fail on cygwin
214
b2f967ef
TC
215 - catch an invalid matrix parameter to convert() instead of crashing
216 https://rt.cpan.org/Ticket/Display.html?id=79922
217
218 - remove the 16-bit/sample limitation from the documentation for
219 setsamples(), it hasn't applied for many releases.
220 https://rt.cpan.org/Ticket/Display.html?id=79989
221
9673d97e
TC
222 - don't copy setsamples() data parameter, it may be a large scalar

TC
228 - pass the --verbose command-line option through to Imager::Probe in
229 sub-module's Makefile.PLs
230 https://rt.cpan.org/Ticket/Display.html?id=75878
231
e9daa5af
TC
232Enhancements:
233
234 - support for giflib 5.0. (5.0.1 and later)
235 https://rt.cpan.org/Ticket/Display.html?id=79029
236 The giflib API Imager uses doesn't have a mechanism to set the
237 header version in 5.0.0.
238
239 - update the GIF library probe code to check for the new giflib 5.0.1
240 EGifSetGifVersion() function, and to check for the giflib 4.2.0
241 uninitialized gif89 bug.
242 https://rt.cpan.org/Ticket/Display.html?id=79679
243 http://sourceforge.net/tracker/?func=detail&aid=3574283&group_id=102202&atid=631304
244
245 - avoid static variables when capturing IPTC data from JPEG files
246
247 - match Imager::Font;:T1's error message translations to those from
248 later versions of T1Lib.
249
250 - for libtiff versions that support extended warning handlers (3.8.0
251 or later), use them to avoid some global variables.
252
253 - note Image::ExifTool for better metadata support.

TC
256Imager 0.92 - 14 Aug 2012
257===========
258
b1c75496
TC
259 - giflib 4.2 eliminates the GIF_LIB_VERSION macro, handle that
260 correctly for both probing and runtime.
261 https://rt.cpan.org/Ticket/Display.html?id=77672
262

268===========
269
ef84bb32 270Bug fixes:
38742a13 271
289d65f4
TC
272 - The size of rotated images is no longer rounded up so aggressively.
273 Added rounding to the linear interpolation done for rotate() and
274 matrix_transform() for 1 and 3 channel 8-bit images.
275 Adjusted the two tranlate matrices used to build the final rotation
276 matrix to use the distance between the outlier pixels rather than
277 the pixel dimensions (ie. dimension-1).
278 With all of this the output of rotate(degrees => 270) on an 8-bit
279 image exactly matches the output of rotate(right => 270).
280 https://rt.cpan.org/Ticket/Display.html?id=77063
281
ef84bb32
TC
282Other changes:
283
284 - eliminate the old IIM_new(), IIM_DESTROY() names from Imager's
285 internals, those names only matter for the XS interface.
286
287 - improve error reporting when PERL_INITIALIZE_IMAGER_CALLBACKS finds
288 the API level compiled into a loadable module such as
289 Imager::File::GIF doesn't match that of Imager. Previously it
290 could be difficult to determine exactly which module was failing to
291 load.
292 https://rt.cpan.org/Ticket/Display.html?id=77173
293
294 - added Imager->check_file_limits() as an interface to the
295 i_int_check_image_file_limits() API.
296
297 - Imager->set_file_limits(reset => 1) now resets the limits to the
298 defaults rather than setting them all to unlimited.
299
300 - wrote a brief security note as Imager::Security
301 https://rt.cpan.org/Ticket/Display.html?id=68910
302
6f31dd14 303Imager 0.90 - 30 Apr 2012
7c4464f5
TC
304===========
305
306Bug fixes:
307
308 - Imager::Test::is_imaged() attempted to process an "epsilon"
309 parameter but the prototype didn't allow for the extra parameter.
310 Corrected the prototype.
311
29b38678
TC
312 - when downconverting samples (eg. from floating point to 8 bit)
313 Imager now rounds the sample value rather than attempting to
314 allocate input values over output values equally. The old
315 behaviour had the probably surprising effect of converting a
316 floating point 2.1/255.0 into an 8-bit 3 rather than the expected
317 2.
318 This may result in slightly different 8 or 16-bit output images.
319
e2a86bac
TC
320 - BI_BITFIELD BMP images were handled incorrectly, both in
321 incorrectly calculating the space required for the masks and in
322 processing the image data itself.
323 https://rt.cpan.org/Ticket/Display.html?id=76736
324
325 - some odd width BMP BI_RLE4 images use run lengths that run one off
326 the edge of the image. Imager now allows this, discarding the
327 extra column.
328
329 - odd length RLE4 runs in BMP images were decoded incorrectly.
330
82eb0687
TC
331 - pkg-config could sometimes return a library that was in a directory
332 EU::MM / $Config{libpth} doesn't know about, but the compiler did.
333 If no -L is included in the pkg-config library information check if
334 EU::MM can find the library, and if not, search our configured
335 directories and insert that into the library flags.
336 https://rt.cpan.org/Ticket/Display.html?id=75869
337
de50f459
TC
338 - Imager::Probe can now probe for libraries with dependent libraries,
339 common for static linking, eg. libpng requires libz.
340 https://rt.cpan.org/Ticket/Display.html?id=74043
341
342 - libpng 1.5 specific probes were looking for libpng 1.4 filenames.
343
344 - added alternative probe configurations that try to link libz, to
345 handle a statically linked libpng.
346 https://rt.cpan.org/Ticket/Display.html?id=74043
347
348 - if a probe includes testcode, Imager::Probe now checks that code as
349 part of the process of checking each configuration rather than as a
350 post test of the found configuration. This allows alternate
351 configurations to be checked if a matching but non-working
352 configuration is found.
353 https://rt.cpan.org/Ticket/Display.html?id=74043
354
9d5ff8a6
TC
355Other changes:
356
357 - when reading or writing images via callbacks, the default callbacks
358 now push an error message indicating that a required callback was
359 called but not supplied.
360 https://rt.cpan.org/Ticket/Display.html?id=76782
361
362 - clarify which callbacks are required for reading and writing TIFF
363 images.
364
365 - improve logging for creation of callback I/O layers.
366
de50f459
TC
367 - a little more documentation for Imager::Probe.
368
594f5933
TC
369 - the i_get_file_background() and i_get_file_backgroundf() APIs now
370 return int to indicate whether the i_background tag was found.
371
1b46057d
TC
372 - PNG rework
373 - improve error reporting
374 - add png_interlace, png_bits tags
375 - read paletted images as paletted images, including transparency
376 - read 1 bit greyscale images as a type suitable for other file
377 handlers to write as bilevel
378 - read 16 bit/sample PNG as 16-bit/sample Imager images
379 - write "bilevel" paletted images as 1 bit grayscale images
380 - write paletted images as paletted images
381 - write 16-bit (or higher)/sample images as 16-bit/sample PNG
382 images
383 - improved metadata support

a5919365
TC
401 - Imager (and the bundled dynamic modules) no longer fallback to
402 using DynaLoader if loading via XSLoader fails.
403 For the bundled modules this could hide useful error messages.
404 https://rt.cpan.org/Ticket/Display.html?id=75560
405
335078fc
TC
406 - IM_DEBUG_MALLOC mymalloc() no longer sn?printfs() a string to a

408 pointer and line number.

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

425 - note that the generator of the apparently non-DFSG-free postscript
426 in MMOne.pfb is a Debian package.
427
02323e69
TC
428 - setsamples() is now a true complement to getsamples() - it can
429 write 8-bit or floating point samples from a scalar or array
430 reference. This adds i_psamp() and i_psampf() to the C level API.
431
432 - the XS interfaces to i_gsamp(), i_gsampf() and i_gsamp_bits() have
433 changed to make better use of the typemap, but these aren't part of
434 the perl level API anyway. There were no changes to the C level
435 interfaces to these functions.
436
2a27eeff
TC
437 - getpixel() and setpixel() now accept a mix of scalar and array
438 references for the x and y parameters, and unequal array lengths is
439 no longer an error.

590 - io_glue I/O buffering re-work:
591
592 - reorganize io_glue to do it's own buffering by default
593
594 - the unbuffered functions are available as i_io_raw_read() (or
595 raw_read() from perl) etc but are not recommended for typical
596 use.
597
598 - use the new i_io_peekn() when checking for file magic to avoid
599 seek, allowing Imager to detect the file type and read the file
600 from an unseekable stream (for formats that don't use random
601 access)
602
603 - added several new I/O layer API functions.
604
605 - fix the TGA performance problem, most noticably on Win32
606 https://rt.cpan.org/Ticket/Display.html?id=70037
607
608 - TIFF now uses wrapper functions of the correct types to avoid casts
609 https://rt.cpan.org/Ticket/Display.html?id=69912
610
611 - the callback IO object did its own buffering, controlled by the
612 maxbuffer parameter supplied to the read() and write() methods.
613 This buffering has been removed, to avoid redundancy with the
614 common io_glue buffering. This also avoids a bug in that code
615 which could rarely pass a zero length to the read callback and
616 then panic about the result.
617
618 - the callback IO object now tests the result of calling the close
619 callback, which should return true for success.
620
621 - the PNM reader did its own buffering. This buffering has been
622 removed to avoid redundancy with the common io_glue buffering.
623
624 - previously the read handlers for fd and callback I/O layers would
625 call the underlying interface (POSIX read or your supplied callback)
626 until it filled the buffer. It now only makes one call.
627
628 - added public constructors for I/O layer objects (see Imager::IO)
629
630 - all core file handlers now use the i_io_foo() wrappers to gain
631 access to buffered I/O rather than calling the I/O layer
632 callbacks directly.
633
634 - all core file handlers now check for error on close.
635
636 - Backward compatibility: if you hava custom file handlers, you can
637 use i_io_write() etc since they're available as macros in older
638 versions of Imager.
639
640 - eliminate the final remnants of io_glue_commit_types().
641
642 - bump IMAGER_API_VERSION, since the above may break assumptions.
643
644 - removed the long unused i_gen_reader() and i_gen_writer() utility
645 functions.

708Development release as a sanity check for the types re-work.

TC
709
710Massive types re-work:
711
712 - the type used internally for pixel co-ordinates and image sizes is
713 now 64-bit on 64-bit platforms (at least sane ones).
714
715 - size_t is now used consistently for memory block sizes.
716
717 - since this changes the binary interface, the Imager API version has
718 been incremented. Any module that uses the API will need to be
719 rebuilt. In most cases that will be enough, but calls to any APIs
720 that take a pointer to image sizes may need source changes.
721
722 - you should be able to create very large images on 64-bit systems,
723 if you have enough memory. Successfully created a 32768 x 49192 x
724 3 channel image, filled with a tiled image and scaled it. The
725 unscaled image was also successfully saved to a JPEG.
726
727 - check the image size before attempting to write BMP, GIF, JPEG,
728 PNG, SGI, TGA, TIFF images.
729
730 - correctly handle reading TGA images over 32767 pixels wide or tall.
731
732Incidental changes:
733
734 - the gif_left and gif_top tags are now clamped to non-negative
735 values when writing a GIF image.
736
737 - removed dead callback read/write code
738
739The default maximum memory size when reading files is now 1G.

1349 - Possible security issue: The floating point sample path for image
1350 based fills had a buffer overflow. This would overwrite the end of
1351 a malloc()ed buffer with double precision floats.

1355 - check that the result of fileno($fh) is defined rather than simply
1356 true when read() or write() is supplied with an fh parameter.
1357 http://rt.cpan.org/Ticket/Display.html?id=35139
1358
1359 - i_scale_axis() wasn't checking the result of i_img_new_ch()
1360 resulting in a SIGSEGV when attempting to scale an image to a size
1361 too large to fit in memory. This is a NULL pointer access issue,
1362 not a buffer overflow.
1363 Added a check for the failure.
1364 scale_calculate() (and hence scale()) will now fail if any of the
1365 scale size parameters are a reference.

1377This release primarily contains changes to improve ease of use -
1378rather than you having to convert images to the appropriate number of
1379channels, Imager handles it internally. How to handle drawing colors
1380and the default combine mode is a thornier problem left for some other
1381release.

TC
1386 - moved the imtoc.perl code into Imager::Preprocess
1387
1388 - paste() and rubthrough() now adapt the source image data to the
1389 destination, so you can now safely paste/rubthrough from greyscale
1390 images to color images or back, or from alpha channel images to
1391 noalpha channels or back.
1392 https://rt.cpan.org/Ticket/Display.html?id=30908
1393
1394 - rubthrough() now falls back to pasting when the source doesn't have
1395 an alpha channel. This effectively treats the source as having a
1396 max alpha channel, the right thing to do.
1397 http://rt.cpan.org/Ticket/Display.html?id=29944
1398
1399 - re-worked most of the area filling code to use a common set of
1400 functions when filling.
1401 Corrected normal combine mode.
1402 Rewrote most of the combine modes to match the way the SVG draft
1403 defines them with respect to a translucent source and destination.
1404 Added tests for translucent source and destination.
1405 Added tests to check 8-bit/sample and double/sample combines work
1406 similarly.

1430 - mixing qtype scaling now sets all channels of a pixel to zero if

1442 - some TGA images weren't being detected correctly as TGA images
1443 https://rt.cpan.org/Ticket/Display.html?id=32925
1444
1445 - handling of the left-over bit for 16-bit/pixel TGA images has been
1446 changed to match the behaviour of the GIMP. Previously the bit
1447 being set was treated as an opaque pixel, but one user reported a
1448 problem with loading such an image. I haven't been able to find any
1449 tools beyond the GIMP that handle alpha-channel 16-bit TGAs, so
1450 I'll match it's behaviour. See issue 114913 in the GIMP's
1451 bugzilla.

1461 - the old dynaload code used Mach API functions to load dynamic
1462 libraries on Mac OS X. These APIs have been deprecated in OS X
1463 10.5 and were causing some build problems.
1464 So henceforth Imager uses the dlopen() family of functions, and you
1465 will need version 10.3 or later of OS X.

1758 - force flushing of the output from i_tt_dump_names() and test output
1759 in t/t35ttfont.t to prevent output from being mixed up.
1760 https://rt.cpan.org/Ticket/Display.html?id=24859
1761
1762 - rewrite a conditional expression as an if() to hopefully work around
1763 a bug in the pre-4.0 GCC Apple shipped with OS X 10.4.
1764 https://rt.cpan.org/Ticket/Display.html?id=25561
1765
1766 - avoid Data::Dumper in regops.perl to support older releases of perl

1769Imager 0.55 - 16 Dec 2006
1770===========
1771
1772This is primarily a bug fix release.
1773
1774Note: Test::More is now a pre-requisite for Imager and is no longer bundled.
1775
1776There is one new feature:
1777
1778 - the Win32 font driver now supports UTF8 (RT 22166)
1779 http://www.cpanforum.com/threads/3276
1780 http://rt.cpan.org/Ticket/Display.html?id=22166
1781
1782Several bugs were fixed:
1783
1784 - the string() method would not output the string "0"
1785 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1786
1787 - fills.c was failing to compile on Solaris 10 (compiler unknown)
1788 http://rt.cpan.org/Public/Bug/Display.html?id=21944
1789
1790 - the gif_disposal and gif_user_input tags weren't being read from
1791 the file correctly
1792 http://rt.cpan.org/Public/Bug/Display.html?id=22192
1793
1794 - gif.c was failing to build under MSVC
1795 http://rt.cpan.org/Ticket/Display.html?id=23922
1796
1797 - in some cases strings passed to the string() method were treated as
1798 terminated by NUL (chr 0)
1799 http://rt.cpan.org/Public/Bug/Display.html?id=21770
1800
1801 - on "MSWin32" perl builds we now link to -lzlib instead of -lz since
1802 that's the default build name for zlib on Win32.
1803 http://rt.cpan.org/Ticket/Display.html?id=23064
1804
1805 - search $Config{incpath} for headers too, which we should have been
1806 doing all along.
1807
1808Win32 font driver fixes:
1809
1810 - the global descent value from bounding box was the wrong sign
1811 http://www.cpanforum.com/threads/3276
1812
1813 - if the first or last glyph overflowed the left or right side of the
1814 advance width they would be clipped
1815
1816
1817Imager 0.54 - 14 Sep 2006
1818===========
1819
1820This is primarily a feature release:
1821
1822 - a new qtype value 'mixing' has been added to the scale()
1823 method. This is faster than 'normal', slower than 'preview'. This
1824 is based on the method used by pnmscale, and seems to produce less
1825 blurry results than normal.
1826 http://rt.cpan.org/Public/Bug/Display.html?id=20677
1827
1828 - the rubthrough() method can now render onto images with an alpha
1829 channel.
1830 http://rt.cpan.org/Ticket/Display.html?id=20678
1831
1832 - the read_multi() method now falls back to calling doing a single
1833 image read via the read() method and write_multi() will now fall
1834 back to calling write() if a single image is supplied. This means
1835 you can simply call the read_multi() or write_multi() functions
1836 without having to check if the type is formatted by that method.
1837 http://rt.cpan.org/Ticket/Display.html?id=19457
1838 http://rt.cpan.org/Ticket/Display.html?id=19458
1839
1840 - the GIF loop extension can now be written. If you don't have
1841 libungif/giflib 4.1.4 (or some distribution's bugfixed equivalent) you
1842 should upgrade.
1843 http://rt.cpan.org/Ticket/Display.html?id=21185
1844
1845 - getscanline() and setscanline() can now read/write palette index
1846 based data from/to the image for paletted images, by setting type to
1847 'index'.
1848 http://rt.cpan.org/Ticket/Display.html?id=20338
1849
1850 - we no longer hassle you to disable GIF support
1851 http://rt.cpan.org/Ticket/Display.html?id=20687
1852
1853 - minor documentation fixes
1854
1855
1856Imager 0.53 - 26 Jul 2006
1857===========
1858
1859This is a bugfix release.
1860
1861Some test code was left in a code path not covered by the test
1862suite. A test was added to cover this code path and the test code was
1863removed.
1864http://rt.cpan.org/Public/Bug/Display.html?id=20705
1865
1866
1867Imager 0.52 - 25 Jul 2006
1868===========
1869
1870This is primarily a feature release, but contains a fair few bug
1871fixes, new features:
1872
1873 - ability to read and write MS Windows ICO and CUR files
1874
1875 - you can now add file format plugins to support new file formats
1876
1877 - add POD coverage tests
1878
1879 - setcolors() and addcolors() now accept color names and so on
1880 instead of requiring Imager::Color objects.
1881 http://rt.cpan.org/Ticket/Display.html?id=20056
1882
1883 - flood_fill() can now fill to a specified border color instead of
1884 just to the area the same color as the seed.
1885 http://rt.cpan.org/Ticket/Display.html?id=19618
1886
1887
1888Bug fixes:
1889
1890 - bounding_box for the T1 driver wasn't converting UTF8 to ascii when
1891 calculating the advance width.
1892 http://rt.cpan.org/Public/Bug/Display.html?id=20554
1893
1894 - bounding_box for the T1 driver wasn't including leading and
1895 trailing spaces in the bounding box as the other drivers did, it also
1896 produced strange results for empty strings or strings containing only
1897 spaces
1898
1899 - when reading CMYK jpeg images they were being transferred to the
1900 image object as is, producing a four channel image. It only looked ok
1901 due to an old still unfixed Photoshop bug. We now convert from the
1902 inverted CMYK that photoshop (and Corel for example) produce into RGB.
1903 http://rt.cpan.org/Ticket/Display.html?id=20416
1904
1905 - reading a CYMK TIFF would result in a 4 channel image, reading any
1906 image with more than 4 channels (eg. RGB with 2 alpha channels) would
1907 result in an error.
1908 http://rt.cpan.org/Ticket/Display.html?id=20415
1909
1910 - added /usr/local/include to the default include search path, since
1911 we were already searching /usr/local/lib for libraries.
1912
1913And various minor fixes and documentation updates.
1914
1915
1916Imager 0.51 - 23 Apr 2006

1920 a crash
1921 http://rt.cpan.org/Public/Bug/Display.html?id=18496
1922
1923 - fix mis-processing of the src_maxx and src_maxy parameters of the
1924 paste() method
1925 http://rt.cpan.org/Public/Bug/Display.html?id=18712
1926
1927 - fix a problem in Imager's "smart" handling of the color parameter

1930
1931
1932Imager 0.50 - 29 Mar 2006
1933===========
1934
1935 - CRITICAL: fixes a segmentation fault from attempting to write a 2
1936 or 4 channel image to jpeg or a 2 channel image to tga where the
1937 output is an in-memeory buffer.
1938 http://rt.cpan.org/Public/Bug/Display.html?id=18397
1939
1940 - fixes an incorrect pointer parameter in the PNG code
1941 http://rt.cpan.org/Public/Bug/Display.html?id=18051
