Magick++ ChangeLog |
2008-10-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- Makefile.am: The Magick++ build was supposed to be optional. Now
it is.
- Makefile.am: Eliminated .tar.bz2 and .zip packages from the
distribution. The .tar.bz2 package was hardly smaller than the
.tar.gz package so it wasted 5.9MB with little benefit. The
compression ratio on the .zip archives is absolutely terrible so
eliminating zip eliminates huge 9.6MB and 25MB files from the
distribution equation. Windows users can easily learn how to use
the vastly more efficient 7-Zip format.
2008-10-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Rationalize OpenMP tests to make sure that OpenMP
can not be enabled without thread support.

performance.
2008-10-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- pragma omp parallel for: Use consistent static scheduling
throughout and ensure that 64 threads can be usefully engaged on a
1024 row image.
- magick/pixel_iterator.c (SetRegionThreads): Implement logic so
that pixel iterators execute single-threaded when invoked on tiny
regions.
- magick/pixel_cache.c (SetNexus): Make staging buffer memset()

implemented so remove unfinished stub code.
2008-10-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c (SetImageDepth): Needed to assign image depth
attribute to user-specified depth rather than only altering the

- magick/pixel_cache.c (AcquireThreadViewPixels): Convert thread
set view convenience methods into library methods because the
inline methods were causing the Sun Studio compiler to produce
thread unsafe code. Due to likely beneficial inlining in the
library, this is not expected to cause any performance impact.

which enables useful multi-threading. Therefore, the cache view
interfaces are now made OpenMP-safe via a global critical section.
2008-09-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/pixel_iterator.c: Reduce use of critical sections around
pixel cache to the bare minimum based on analysis and testing.
Unfortunately, testing shows that the pixel cache views are still
not 100% thread safe so the extra locking is still required.
- magick/pixel_cache.c (ModifyCache): Make implementation thread

- coders/dcm.c (ReadDCMImage): Report actual image depth.
- magick/resource.c (InitializeMagickResources): Set default
maximum memory limit to physical memory rather than 2X physical
memory. This decision is made since the system paging device is

is likely faster.
- magick/blob.c (OpenBlob): The MAGICK_IO_FSYNC environment
variable causes output files to be synchronized to disk when set
to TRUE.

dropped in the new makefiles for GraphicsMagick 1.2. Resolves
SourceForge bug 2005883.
- magick/color.h (NotColorMatch): New macro for testing that two
colors are not the same. Opposite from existing ColorMatch().

request a particular image type.
- coders/pdf.c (Huffman2DEncodeImage): Explicitly request a strip
per page when writing Group4 TIFF.
- coders/tiff.c (WriteTIFFImage): Place a generous default limit
on rows-per-strip when using Group3 or Group4 FAX compression.
The default limit is added since it is observed that the Group4
compressor fails with extremely huge strips. Added a define
"tiff:rows-per-strip" to allow the user to explicitly set the rows
per strip. Added a define "tiff:strip-per-page=true" to allow the
user to force one strip per page no matter what. Added progress
monitor support to tile writer.

then the DPX format writer will request the required storage from
the filesystem in advance (if supported by the OS) or the full
amount of memory required (when writing to an in-memory BLOB).

operators (-operator) for applying noise to one or more channels.
The additional operators are Noise-Gaussian, Noise-Impulse,
Noise-Laplacian, Noise-Multiplicative, Noise-Poisson, and
Noise-Uniform. The amount of noise applied is controlled via the
numeric argument, which can specify the percentage of noise to
apply.
- magick/enum_strings.c: New source module to contain the various
EnumToString() and StringToEnum() functions which seem to multiply
like bunny-rabbits.
- magick/gem.c (GenerateNoise): Poisson noise generation was
taking excessively long and producing wrong results. Noise
generation was only producing the correct amount of noise in the
Q8 build.
(GenerateDifferentialNoise): New function to return noise in a
floating-point differential format.
2008-06-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

functions for the composition operations.
- coders/xcf.c (ReadXCFImage): Deal with grayscale images the
GraphicsMagick-way.

channels to individual files.
2008-05-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

feature since range checking is not where the CPU time is going.
- magick/effect.c (UnsharpMaskImage): Re-write implementation to
use pixel iterators.
- magick/pixel_iterator.c: Decided that the old per-pixel
iterations were not useful enough to keep since the region-based
ones are working fine. Moved pixel_row_iterator.c to

colorspace of composite image so that it is compatible with canvas
image.
- magick/alpha_composite.h (AlphaComposite): Fix alpha composite
when both pixels contain transparency.

- magick/composite.c (CompositeImage): CMYK copy composition
operators automatically set the image colorspace to CMYK.
- coders/tiff.c (WriteTIFFImage): CMYK must take precedence over
JPEG compression. We don't support JPEG compression in TIFF with
CMYK.
2008-05-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/effect.c (ChannelThresholdImage): Re-implement using
pixel iterators. Support thresholding only the red channel by
eliminating the switch to intensity thresholding if only one
channel parameter is supplied.
- coders/tiff.c (WriteTIFFImage): Don't accidentially convert CMYK
images to RGB.
- magick/composite.c (CompositePixels): Handle CopyBlack properly
for CMYK images.
- magick/command.c (CompositeImageCommand): Support CopyCyan,
CopyMagenta, CopyYellow, and CopyBlack.
- magick/composite.c (CompositeImage): Preserve the canvas image
colorspace.
- doc/options.imdoc: Remove mention of thresholding at the channel
level since this never worked in a useful fashion and now only
simple intensity thresholding is available via -threshold.
- magick/command.c (MogrifyImage): Revert to using ThresholdImage() rather
than ChannelThresholdImage().
- PerlMagick/Magick.xs: Revert to using ThresholdImage() rather
than ChannelThresholdImage().

- magick/effect.c (AddNoiseImage): Implemented using pixel
iterators.
- magick/pixel_row_iterator.c (PixelRowIterateDualNew): New pixel

dependent applications will pick up this dependency without
themselves needing to enable OpenMP.
- magick/command.c (CompositeImageList): Don't overwrite matte
flag for CopyOpacity composition.
- magick/composite.c (CompositeImage): CopyOpacity composition
needs the opacity channel to be enabled.

AssignQuantumOp, ThresholdQuantumOp, ThresholdBlackQuantumOp, and
ThresholdWhiteQuantumOp.
2008-05-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/command.c (VersionCommand): Report if OpenMP is supported
by the build.
- configure.ac, Makefile.am: Install documentation according to
the conventions established by the configure script. This
installs the documentation under
/usr/local/share/doc/GraphicsMagick by default.
2008-05-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- scripts/format_c_api_docs: Add pixel_iterator.c and
pixel_row_iterator.c to API documentation formatter.

'description' argument and progress monitor support.
(PixelIterateDualModify): Add a
'description' argument and progress monitor support.
- magick/resize.c (HorizontalFilter, VerticalFilter): Switch back
to RoundSignedToQuantum() since some pixels were experiencing
underflow. Localize some variables so that we don't have to
declare them as private for OpenMP.
2008-05-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac, magick/resize.c, PerlMagick/Makefile.PL.in: Added
OpenMP support for parallelizing a task across multiple cores.

(RegisterMagickInfo): Remove any existing entry since module
loading may result in duplicate entries.
2008-05-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- libtool: Update to libtool 1.2.4.
- magick/magick.h (MagickInfo): Store string attributes as 'const
char *' to statically allocated data rather than as heap allocated
strings. THIS IS AN INTERFACE CHANGE. Using a coder written to
the old interface is non-fatal but may resemble a small memory
leak. The reason for the change is to avoid at least 880 needless
malloc()/strlen()/strlcpy() operations at initialization time, and
at least 880 free() calls at destruction time. While these
operations did not take long, they are still an unnecessary
overhead, which is increased in thread-safe applications.
- magick/module.c (OpenModule): Ignore requests to open modules
which have already been opened.
- GraphicsMagick.spec.in: Add --with-included-ltdl to the default
options since this seems safest until the libltdl validation logic
is fully robust. This should be made user-configurable in the
future.
- magick/Makefile.am (magick_libGraphicsMagick_la_LIBADD): Apply
libltdl dependency argument as required for building.
- configure.ac: Intuit if the GraphicsMagick library will depend
on -lltdl.
- Magick++/bin/GraphicsMagick++-config.in: Use substitutions
rather than invoking GraphicsMagick-config in order to determine
GraphicsMagick library usage requirements. This avoids problems
when GraphicsMagick-config is not in the executable search path.
2008-05-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- GraphicsMagick.spec.in: NEWS was renamed to NEWS.txt. Enable
libtool verbose output so it is possible to diagnose build
failures.
2008-05-01 Fojtik Jaroslav <JaFojtik@seznam.cz>
- mat.c: gm convert -limit Pixels 1 input_gray_lsb_16bit.mat crap.miff
don't rotate partial image.

of the list rather than maintaining alpha order.
- magick/image.c (DestroyImageInfo): Tidy up and simplify code.
- magick/constitute.c (WriteImage): Comment out the "bi-modal

The test suite passes without it.
- magick/magick.h (struct MagickInfo): There is no need for 'name'
to be allocated data so make it const.
(DestroyMagickInfo): Add a static function to destroy a MagickInfo
structure. Renamed previous DestroyMagickInfo to
DestroyMagickInfoList and made it static.
2008-04-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- version.sh: GraphicsMagick 1.2 released.
CVS head is now 1.3 development.

CPU.
2008-04-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/magick.h (MagickInfo): Remove image_info member since I
can not find any purpose for it.
- coders/tiff.c (WriteTIFFImage): Remove assertion check on
scanline size since it has not caught anything.
- magick/image.c (SetImageInfo): Ensure that the file extension
does not trigger unwanted activity such as access to an X11
server, printer, or the launch delegate.
- config/Makefile.am (configshare_DATA): Install colors.mgk in
share path.
- magick/blob.c (GetConfigureBlob): Search 'share' config path
prior to 'lib' config path.
2008-04-25 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/png.c (WriteOnePNGImage): TrueColor RGB was usually
written rather than the desired more compact format. This is a
first pass at fixing that.
2008-04-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- BENCHMARKS.txt: Added a benchmark summary.
2008-04-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>

supposed to be using it!
- libtool: Updated to GNU libtool 1.2960 2008-04-19.
- configure.ac, magick/delegate.h: It seems that the modern
convention is to store ghostscript headers in a subdirectory
called 'ghostscript' rather than 'ps'.
We don't actually need Ghostscript errors.h and that is a good
thing since it seems that some newer Ghostscript calls it ierrors.h
2008-04-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- VisualMagick/installer/inc/files-dlls.isx: Comment out inclusion
of X11 support DLLs.

2008-04-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Updated to Autoconf 2.62.
2008-04-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/command.c (MogrifyImageCommand): New -create-directories
option automatically creates subdirectories as needed when
-output-directory option is used. This is useful when one
directory tree of files is being mogrified to a new tree.
2008-04-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/utility.c (MagickCreateDirectoryPath): New function to
create a directory path. Will be used later.

assertion to hopefully flush out any remaining cases where
ExportImagePixelArea() writes past the end of its buffer.
- magick/constitute.c (ExportImagePixelArea): GrayQuantum case for
DirectClass pixels was sometimes writing a zero byte one past the
end of the allocated buffer. Thanks to Josue Gomes for reporting
this bug.
2008-04-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/{pcd.c,pcx.c,pdb.c,pict.c,stegano.c,wpg.c,xcf.c}:
Warnings reduction.

2008-03-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- CONTRIBUTE.txt: Convert contribute.html to reStucturedText
format and generate HTML version from it.
- PROCESS.txt: Convert description of development process to
reStucturedText format and generate HTML version from it.
- INSTALL-windows.txt: Add instructions for how to install from
setup.exe style installer. Also add instructions for how the
distribution package is built.
- Copyright.txt: Reformat in reStucturedText format and generate
HTML version from it.
- VisualMagick/installer/inc/body.isx: No longer include
development headers and libraries in the Windows DLL install
package since they are large and they may only work with the
version of Visual C++ used to perform the build. It is much safer
for the developer to build the package from source with his own
compiler.
2008-03-27 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- Fix compilation issues with Microsoft Visual Studio.

(TransformRGBImage): Fix loop iterator which was looping one past
the end of the array. Reported by Kai-Uwe Behrmann.
- magick/command.c: Added a -set option to the composite, convert,
display, mogrify, import commands in order to allow setting an
image attribute.
2008-02-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- PerlMagick/Magick.xs: Use MagickAcquireMemory() rather than
AquireMemory().
- coders/xwd.c (ReadXWDImage): Eliminate integer overflow
vulnerability (IDefense 09.19.07).

- coders/tiff.c (WriteTIFFImage): The RFC 2301 specification for
Internet FAX recommends LSB2MSB fill order so document that.
2008-02-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/tiff.c (WriteTIFFImage): Use '-define
tiff:fill-order={msb2lsb|lsb2msb}' to control TIFF bit fill order.
2008-02-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Updated to latest CVS libtool.
- coders/tiff.c (CompressionSupported): Use
TIFFGetConfiguredCODECs() to test if a requested compression type
is supported by libtiff. Based on advice from Frank Warmerdam.
- configure.ac: Add test for TIFFGetConfiguredCODECs() in libtiff.
2008-02-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/tiff.c: With libtiff 3.6.1, including tiff.h and tiffio.h
is not sufficient to obtain the definitions from tiffconf.h so
libtiff is assumed to not support any features, such as
compression. Avoid this problem by explicitly including
tiffconf.h if it is found. This resolves SourceForge issue
[1883527] compression of tiff-file has no effect.
2008-02-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- VisualMagick/installer/inc/setup.isx: Set Inno Setup installer
compression to "lzma/max".
- PerlMagick/Magick.xs: Eliminate use of memory allocation macros
since these failed miserably under Windows where it seems that
malloc, free, and realloc are redefined via macros by the Perl
build environment. This reverts changes made on 2007-12-01.
- magick/memory.c (MagickAcquireMemoryArray): Use implementation
from the 1.1 branch.
- magick/utility.h: Remove MagickSafeMultiplySize_t since it seems
that use of inline functions in Windows is a disaster area.
2008-02-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- Makefile.am (windows-dist): Create a 7z compressed Windows
comprehensive source package. See http://www.7-zip.org/ for
information on Windows 7-Zip and http://p7zip.sourceforge.net/ for
information on portable 7-Zip (P7ZIP).
2008-02-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- coders/tiff.c (WriteTIFFImage): Add logging for image resolution
and resolution units.
- magick/version.h.in: Update copyright year to 2008.
2008-02-01 Gary V. Vaughan <gary@gnu.org>
- configure.ac: Updated for libtool-2.1b.
- bootstrap (libtoolize): Libtoolize can figure out the mode and
directory for libltdl from configure.ac.
2008-01-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
- magick/Makefile.am: Update
magick_libGraphicsMagick_la_DEPENDENCIES to use LTDLDEPS.
2008-01-26 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/image.c (SetImageInfo): Successfully read existing file
names in the form file[123] which were failing to read since they
appear to be a valid sub-image specification.
2008-01-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/utility.c (ExpandFilenames): If a filename appears to
contain a wildcard specification, first check to see if there is
file matching the unexpanded wildcard prior to engaging in the
slow task of wildcard expansion. Without this fix, expanding the
command line takes a very long time if there are a huge number of
files in the directory, and some file names appear to contain
wildcard specifications. Inspired by SourceForge bug reports [
1878992 ] "literal square brackets in file name cause large delay"
and [ 1783209 ] "converting runs slowly when subimage is
specified", but this might not be the complete fix for the
problem.
2008-01-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- Makefile.am: Update to Automake 1.10.1 and enable generation of
an lzma compressed source package.
2008-01-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Added configure option --with-umem to enable use
of the umem memory allocation library available in Solaris 9,
Update 3 and later, or from
https://labs.omniti.com/trac/portableumem/. This library supports
concurrency in multi-threaded programs and supports debugging
memory issues. See
http://developers.sun.com/solaris/articles/libumem_library.html
for a description of how to use the library for debugging memory
issues.
2008-01-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/command.c (VersionCommand): Include a "Large Memory" item
in the Feature Support list.
- coders/png.c (RegisterPNGImage): Remove reference to dead PNG
ftp site.
- VisualMagick/configure/configure.cpp (InitInstance): Remove
project dependency on dxguid.lib (Direct-X).
2008-01-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- configure.ac: Update libtool to latest CVS version.
2008-01-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
- magick/command.c (DisplayImageCommand): No longer default to
reading standard input if stdin fails isatty() test. This
behavior was causing failure to launch from Gnome and it is
difficult to work around the issue from within a .desktop file.
(AnimateImageCommand): No longer default to
reading standard input if stdin fails isatty() test.
