2007-07-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/utility.h (MagickReallocMemory): It seems that realloc()
frees the provided memory pointer if the requested size is zero.
This was causing MagickReallocMemory() to perform a double-free
under error conditions. Inspired by Debian
realloc_double_free_fix patch by Daniel Kobras.
2007-07-18 Daniel Kobras <kobras@debian.org>
* magick/quantize.c (GrayscalePseudoClassImage): Fix computation
of memory required for colormap index

delegate code (via file names)"
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=345238
2007-07-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/forward.h: New header file to support forward type
declarations.
* coders/pnm.c (ReadPNMImage): Fix pixel scaling problem caused by
floating point rounding error.
2007-07-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

are missing.
* configure.ac: Check for missing pread() and pwrite() prototypes.
* m4/ac_func_fseeko.m4: Use fixed version of AC_FUNC_FSEEKO.
* magick/utility.c (SystemCommand): Avoid use of snprintf.
2007-07-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

available.
2007-07-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/dpx.c (ReadDPXImage): Avoid using seek() if possible, and
don't use at all if the input is not seekable.
* coders/psd.c (ReadPSDImage): Eliminate memory leak when reading
PSD files. Fixes Sourceforge issue 1625477 "Memory leak reading
layered PSD Image".
2007-06-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/command.c: Fixed -affine command argument
validation. Fixes SourceForge issue 1743141 "Affine matrix option
parsing".
* config/magic.mgk: Added detection for BigTIFF.
* coders/tiff.c: Preliminary work to support BigTIFF.
2007-06-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/dpx.c: Fix problems encountered when reading and writing
from/to pipes or compressed files.
2007-06-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/dpx.c (ReadDPXImage): Improved the pixel data marshalling
in order to obtain better read performance for 10-bit DPX.
* magick/blob.c (OpenBlob): Added support for MAGICK_MMAP_READ and
MAGICK_MMAP_WRITE environment variable options to enable input and
output file access using mmap().
2007-06-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/blob.c (OpenBlob): Use MAGICK_IOBUF_SIZE to tune the size
of the I/O buffer. Sometimes performance is improved by using
something other than the current default of 16KB.
2007-06-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/miff.c (ReadMIFFImage): Handle case where compression
keyword is present but has value of `None`.
2007-06-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/blob.c (OpenBlob): Disable reading input files using
memory mapping since it has been learned that some operating
systems fail to do read-ahead on network files. Without
read-ahead, performance is poor.
* magick/resource.c (AcquireMagickResource): Map resource limit
was not being properly checked due to a typo. The memory limit
was being tested instead.
* coders/tiff.c (ReadTIFFImage): Use libtiff to decode OJPEG
compressed files into RGB. Probably requires new OJPEG
implementation from Joris Van Damme which is new in libtiff and
not yet released. I am not completely sure that this approach is
correct yet.
2007-05-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/xwindow.c (MagickXGetWindowImage): Set image->depth
appropriately.
* many files: Compiler warnings reduction.
2007-05-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/cineon.c (ReadCINEONImage): Alter sample scaling
algorithm a bit.
* tests/rwblob.c, tests/rwfile.c: Allow some slop when testing
Cineon format with QuantumDepth=8 since we are currently only
supporting 10 bit samples.
2007-05-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/jpeg.c (ReadJPEGImage): Fix reading 12-bit grayscale
JPEG.
2007-05-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/cineon.c (WriteCINEONImage): Re-wrote Cineon writer from
scratch. There is no code originating from ImageMagick in this
source module any more.
2007-04-30 Fojtik Jaroslav <JaFojtik@seznam.cz>
* coders/art.c, coders.cut.c, coders/mat.c, coders/wpg.c: Add
support for PingImage() so that image identification is fast by
default. Also eliminates error message produced by mat.c due to
rotating an image which has no pixel cache.
2007-04-09 Fojtik Jaroslav <JaFojtik@seznam.cz>
* coders/wpg.c (ReadWPGImage): Fix for SourceForge bug id 1431805
"clip art wpg files cause access violation in graphics magick".
2007-04-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/pixel_cache.c (ModifyCache): Ensure that the cache nexus
is open. Fix for SourceForge bug id 1173713 "segfault in
ModifyCache"
* m4/acx_pthread.m4 (ACX_PTHREAD): Apply fixes necessary to
support C++ compiler properly.
2007-04-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/GraphicsMagick.pc.in: Fix for SourceForge bug id 1576616
"Fix includedir variable in pkg-config files".
* magick/pixel_cache.c (GetOnePixel): Fix for SourceForge bug id
1572357 "GetOnePixel definition appears incorrect". It is true
that this function is intended for read-only purposes and that the
PixelPacket value is returned directly.
* coders/pdf.c (WritePDFImage): Fix for SourceForge bug id 1510075
"Failed to write PDF with JPEG compression".
* magick/command.c (MogrifyImageCommand): Properly bubble up
errors and terminate further mogrify processing immediately. This
in response to SourceForge bug id 1391421 "problem doing resize on
273x1 JPEG".
* magick/magick.c (InitializeMagickClientPathAndName): Fix for
SourceForge bug id 1315109 "segfault in InitializeMagick(NULL)".
* wand/magick_wand.c (MagickGetQuantumDepth): Fix for SourceForge
bug id 1353744 "MagickGetQuantumDepth doesn't work".
* PerlMagick/t/read.t: Added a test for WPG v1.
2007-04-07 Fojtik Jaroslav <JaFojtik@seznam.cz>
* coders/mat.c: Read Matlab files in both big and little endian
format.
2007-03-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/dpx.c (WriteDPXImage): Set DPX reference high quantity to
2.047 rather than 2.048 since zero is assumed to occupy one count
and 2.047 seems to be the convention even though the DPX
specification says the default is 2.048. Technicolor uses 2.047.
* m4/acx_pthread.m4: Update version of ACX_PTHREAD macro used.
2007-03-28 Fojtik Jaroslav <fojtik@humusoft.cz>
* coders/wpg.c: Support CTM translation in WPG reader.
2007-03-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/dpx.c: Store 10-bit Luma samples in the filled 32-bit
storage word starting with the datum in the least significant
position.
2007-02-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* Updated autoconf to version 2.61.
2007-02-10 Daniel Kobras <kobras@debian.org>
* coders/palm.c: (ReadPALMImage) Do not implicitly call
ReadBlobByte() twice in Min() macro. Patch thanks to Vladimir
Nadvornik. This was a regression introduced in patch for
CVE-2006-5456. (CVE-2007-0770)
