2008-12-28 Fojtik Jaroslav <JaFojtik@seznam.cz>
* coders/fits.c: Ability to read extension blocks.
* coders/fits.c: Fixed MaxTextExtent limitation of blocks.
2008-12-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* www/OpenMP.rst: Add results for Window Vista 64-bit / AMD Phenom
X4 9550.
* VisualMagick/installer/inc/body.isx: Revert yesterday's change
regarding the placement of config files. Place the config files
in a `config` subdirectory just as before.
2008-12-22 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* VisualMagick/installer/inc/body.isx: They say that when in Rome
you should do as the Roman's do. Based on this philosophy, all of
the coder and filter DLLs are now installed to the same directory
as the executables and DLLs which depend on them. This eases
operation under Windows Vista.
2008-12-21 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/blob.c: First pass at supporting large file access under
Windows.
2008-12-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/resource.c (InitializeMagickResources): Improve resource
estimation for Microsoft Windows systems with large memory.
* magick/segment.c: Added some code to dump histograms with
`-verbose -verbose`.
* coders/tiff.c: Support reading/writing 16 and 24 bit float TIFF
files.
* magick/constitute.c (ExportViewPixelArea): Support exporting 16
and 24 bit short floats. Relies on code developed for
GraphicsMagick by Richard Nolde.
(ImportViewPixelArea): Support importing 16 and 24 bit short
floats. Relies on code developed for GraphicsMagick by Richard
Nolde.
2008-12-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/operator.h (enum QuantumOperator): Added LogQuantumOp,
MaxQuantumOp, MinQuantumOp, and PowQuantumOp enumerations as well
as "Log", "Max", "Min", and "Pow" options to -operator.
2008-12-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/command.c (MogrifyImage): The -write option was not
implemented in a useful fashion and the +write option never worked
at all. Re-implement -write and eliminate +write from the
documentation since +write is not needed.
2008-12-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/tiff.c (ReadTIFFImage, WriteTIFFImage) Support reading
and writing 64-bit integer TIFF.
* magick/constitute.c (ImportViewPixelArea): Add support for
importing 64-bit integer values.
(ImportViewPixelArea): Add support for exporting 64-bit integer
values.
2008-12-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/tiff.c (ReadTIFFImage): Fix bug with reading one bit per
sample RGB images.
2008-12-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/pixel_cache.c (OpenCache): Fix a code ordering problem
which results in `identify` throwing an assertion for PseudoClass
image files. This bug was added in the 1.3.2 release.
* coders/tiff.c (ReadTIFFImage): Fix bug with `ping` mode.
2008-12-07 Fojtik Jaroslav <JaFojtik@seznam.cz>
* coders/fits.c: Proper signed to unsigned conversion for 64 bit LSB images.
2008-12-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/Makefile.am: When X11 is disabled, don't compile the
X11-specific source modules. Don't ever install any X11-related
header files.
2008-12-06 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/segment.c (SegmentImage): Use `double` rather than 64-bit
integer to accumulate totalized values. Make the cluster summary
report more concise.
2008-12-06 Fojtik Jaroslav <JaFojtik@seznam.cz>
* coders/fits.c: Fix for 64 bit images.
2008-12-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/segment.c (SegmentImage): Cluster threshold is expressed
as a percentage of total cluster pixels. Optimize for larger
images.
2008-12-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/segment.c (SegmentImage): Accelerate using OpenMP.
2008-11-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/utility.c (ExpandFilenames): Remove some arbitrary
argument length limits. Pass -convolve argument without any
additional checking. Verify that strings are not truncated during
copy.
(ListFiles): Be more memory efficient.
* magick/fx.c (ConvolveImage): Fix formatting problem when logging
the convolution kernel used.
* magick/utility.c (TranslateTextEx): Support formatting huge
comment text.
2008-11-28 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/fx.c (ConvolveImage): Don`t process opacity channel
unless image has one.
* magick/effect.c (MotionBlurImage): Use
AcquireOnePixelByReference() rather than AcquireImagePixels() to
retrieve one pixel. This is much more efficient.
(AdaptiveThresholdImage): Don`t process opacity channel unless
image has one.
(BlurImage): Don`t process opacity channel unless image has one.
2008-11-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/profile.c (ProfileImage): +profile now supports a simple
exclusion syntax. For example, to strip all of the profiles
except for the ICM profile use +profile '!icm,*'. The new syntax
also allows multiple profile names to be listed at once. The
primary requirement is that all excluded profiles must be listed
prior to those to be stripped.
2008-11-20 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/transform.c (RollImage): Remove image storage class
alteration.
(CompositeImageRegion): Ensure that the canvas image storage class
is correct.
2008-11-19 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* config/delegates.mgk.in: Since we removed support for `spawn` a
long time ago, and no longer execute using the Unix shell by
default, we need to add an ampersand to the end of the two entries
previously using `spawn` so that the display program does not hang
when it invokes the external program.
* utilities/Makefile.am (UTILITIES_TESTS): Add preview-based
tests.
* coders/preview.c (WritePreviewImage): Solarize requires a
threshold argument.
* coders/vid.c (WriteVIDImage): Eliminate memory leak.
* magick/montage.c (MontageImages): Fix continued use of freed
memory.
2008-11-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/omp_data_view.c (AccessThreadViewDataById): New function
to allow retrieving data via the index it was registered with.
* magick/enhance.c (BuildChannelHistograms): EnhanceImage() and
NormalizeImage() now share one common function for generating the
histogram.
* magick/enhance.c (ModulateImage): Improve performance a bit.
(ContrastImage): Improve performance a bit.
(GammaImage): Improve performance a bit.
2008-11-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* www/authors.rst: List Mark Mitchell as an author.
* utilities/tests/msl_composite.sh: Fix `rm -f` without a valid
argument which annoyed NetBSD.
* coders/fits.c: Impose a limit on the length of the row PDU.
Make sure that GraphicsMagick version information does not
overflow the length allowed by a row PDU.
2008-11-16 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/jpeg.c (WriteJPEGImage): Use DCT algorithm default from
the library rather than the header file.
* magick: Adjust OpenMP scheduling options based on observed
behavior.
2008-11-14 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/shear.c (IntegralRotateImage): Added OpenMP acceleration
for rotate by 90 and 270 degrees.
* configure.ac: New --disable-openmp-slow configure for disabling
use of OpenMP for algorithms which may run slower on operating
systems with crummy thread libraries. This still allows gaining
the benefits from OpenMP for CPU hogs. Verified to help with
FreeBSD 7.0 and Apple OS-X Leopard.
* magick/semaphore.c: Trimmed out the debug code in order to
obtain a bit more performance.
2008-11-13 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/jpeg.c: Allow the user to specify the DCT method
(jpeg:dct-method), or if huffman encoding should be enabled
(jpeg:optimize-coding=true). Default the DCT method to the
libjpeg default rather than forcing it to JDCT_FLOAT since float
is slower on some systems.
2008-11-12 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/jp2.c (BlobClose): Leak a little bit less memory when
reading a JP2 file.
2008-11-11 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* wand/wandtest.c: Eliminate memory leak.
* wand/drawing_wand.c (DestroyDrawingWand): Eliminate memory
leaks.

Tenaglia for Red Hat Linux 4.
2008-11-10 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/msl.c: Fix bug with attributes becoming appended to
themselves. Resolves SF issue 2255754. Reflowed code.
2008-11-09 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* version.sh: GraphicsMagick 1.3 released.
Next release on head will be 1.4.
* www/OpenMP.rst: Updated with latest measurement data.
* www/benchmarks.rst: Updated with latest benchmark data.
* coders/url.c (RegisterURLImage): Register HTTP and FTP URL
support in the "unstable" category since these are capable of
accessing the network and therefore represent a potential security
issue. Register the FILE URL support in the "stable" category
since it is capable of incorporating local disk files, which may
still represent a security security issue for server applications.
Note that disabling these functions might cause some existing MSL,
MVG and SVG scripts to stop working if they use external URLs.
2008-11-08 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/pnm.c (ReadPNMImage): Sequential multi-thread the PNM raw
format readers. Can improve read performance quite substantially
for large PBM and PGM files, and less so for PPM. There is most
benefit for systems with more I/O than one CPU core will support.
Systems with slow I/O and a relatively fast CPU may see somewhat
diminished read performance with more CPU consumption. As such,
this is effectively a verification that multi-threading the reader
is possible, and may be of benefit to power-users.
* magick/omp_data_view.c (AllocateThreadViewDataArray): New
function to allocate a thread view data array. Updated modules
using similar code to use this function in order eliminate
useless redundancy.
2008-11-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/pixel_cache.c: Incorporate OMP thread views into the
pixel cache so usage is less invasive. Update OMP-enhanced source
modules to suit.
(GetImagePixelsEx): New function similar to GetImagePixels()
except that it reports exceptions to a user-provided structure.
(SetImagePixelsEx): New function similar to SetImagePixels()
except that it reports exceptions to a user-provided structure.
(SyncImagePixelsEx): New function similar to SyncImagePixels()
except that it reports exceptions to a user-provided structure.
(AccessImmutableIndexes): New function to access read-only
colormap indexes.
(AccessMutableIndexes): New function to access writeable colormap
indexes.
(AccessMutablePixels): New function to access writeable pixels.
(AccessDefaultCacheView): New function to access the default cache
view.
2008-11-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/command.c (BenchmarkImageCommand): With no other
arguments, the benchmark command now defaults to one iteration.
* magick/effect.c (SpreadImage): Offsets array size is a prime
number to help avoid beating.
(SpreadImage): Ensure that spread loops are always terminal.
* magick/utility.c (MagickRandReentrant): Fix bug where rand() was
being continually re-seeded if rand_r() was not available.
2008-11-04 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* utilities/tests/msl_composite.sh: Replace SVG image generation
with simpler approach which properly centers the text. Use our
own font so that tests will pass if the user does not have fonts
installed.
* magick/utility.c (GetMagickDimension): Extend to support parsing
optional x and y offset values and use to fix parsing for
-oil-paint and -unsharp when sscanf() is C'99 compliant.
2008-11-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/pixel_cache.h (AcquireOneCacheViewPixel): Pass pixel to
update by reference.
(AcquireOnePixelByReference): New private inline method which
passes pixel to update by reference.
* magick/omp_thread_view.h (AcquireOneThreadViewPixel): Pass pixel
to update by reference.
* magick/alpha_composite.h (BlendCompositePixel): Replace
BlendComposite with BlendCompositePixel, which passes the
composite pixel by reference.
(AlphaCompositePixel): Replace AlphaComposite with
AlphaCompositePixel, which passes the composite pixel by
reference.
(AtopCompositePixel): Replace AtopComposite with
AtopCompositePixel, which passes the composite pixel by reference.
* configure.ac: With excessive maintenance releases, the library
age portion of MAGICK_LIB_VERSION was overflowing its allotted
space. This resulted in 1.1.X releases reporting the wrong
MagickLibVersion as of 1.1.10. Fix this by supporting up to 99
values for each field.
2008-11-02 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* configure.ac: Fix passing the --with-windows-font-dir option via
DISTCHECK_CONFIG_FLAGS.
* utilities/tests/msl_composite.sh: Integrated MSL composition
test script contributed by Max Hohenegger, Max at hohenegger.eu.
* magick/command.c (ConjureImageCommand): Return status was
inverted so one was returned for command success rather than zero.
2008-11-01 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* png: Updated libpng to 1.2.33 release.
* magick/color.c (FuzzyColorMatch): If fuzz is zero then
completely use the result of ColorMatch() rather than entering
unnecessary expensive code.
2008-10-31 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/studio.h: Make sure we don't conflict with OpenMP
implementation if it is active but we are not using it.
2008-10-30 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/studio.h (HAVE_OPENMP): Add logic to make sure that
OpenMP is only engaged for OpenMP 2.0 or later.
* magick/command.c (VersionCommand): Report OpenMP version.
* 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.

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()
conditional in order to dramatically diminish impact to small
accesses. This memset() only exists to make valgrind happy.

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
pixels.

* 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

2008-09-05 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/pixel_cache.c: Exhuastive study of the pixel cache code
reveals that it is inscrutable and not implemented in a fashion
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

* magick/command.c (CompareImageCommand): Useful options are now
-metric, -highlight-color, and -hightlight-style.
2008-08-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/compare.c (DifferenceImagePixels): Fixed `Annotate`
difference annotation algorithm. Added `Threshold` and `Xor`
difference annotation algorithms.
(GetImageChannelDifference): New function for computing
statistical image error using various metrics. Inspired by
`imgcmp` from Jasper.
(GetImageChannelDistortion): New function for obtaining
statistical image error using various metrics for a specified
image channel. Signature is compatible with similar ImageMagick
function.
(GetImageDistortion): New function for obtaining statistical image
error using various metrics for all the active channels in the
image. Signature is compatible with similar ImageMagick function.
* magick/command.c (CompareImageCommand): Added a `compare`
subcommand which compares two images using various metrics, and/or
generates a difference image using various difference annotation
algorithms. Documentation not yet updated.

* magick/pixel_iterator.c: Split user context in all pixel
iterator APIs into a mutable data part, and an immutable data
part. This required modification to all modules using the pixel
iterator methods.
2008-07-29 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* wand/magick_wand.c (MagickCompareImageChannels): Use
DifferenceImage().
(MagickCompareImages): Implement by calling
MagickCompareImageChannels().
* magick/compare.c (DifferenceImage): The ImageMagick-compatible
CompareImages() function signature was clearly an example of bad
design so rename CompareImages() to DifferenceImage() with a
signature which does not unnecessarily mix functionality and
allows for ease of future expansion.
2008-07-24 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* wand/Makefile.am (WAND_TESTS): Added Wand drawtest and wandtest
to automated test suite.
2008-07-23 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/effect.c (ThresholdImage): Don't read uninitialized pixel
indexes (valgrind gripe).
* coders/tiff.c (CompressionSupported): Use
TIFFIsCODECConfigured() to test if a codec is supported.
* tests/{rwblob.c, rwfile.c}: use DestroyImageList() rather than
DestroyImage().
* coders/psd.c (RegisterPSDImage): Fix module registration memory leak.
* coders/jpeg.c (RegisterJPEGImage): Fix module registration memory leak.
2008-07-18 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* magick/blob.c (DestroyBlob, DestroyBlobInfo): Implementation is
a bit more robust.
2008-07-17 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* coders/jpeg.c (ReadJPEGImage): Remove over-write of
image->client_data. Resolves SourceForge issue [ 2018974 ]
client_data is not passed to streamhandler.
* coders/png.c (WriteOnePNGImage): Fix crash when writing PNG
images with transparency and either type Optimize is requested, or
the image is colormapped.
2008-07-12 Fojtik Jaroslav <JaFojtik@seznam.cz>
* coders/mat.c Fixed problem: "In this case, the referenced
images had previously been deallocated but are still being used.
Since they are overwritten, their signatures are invalid.
2008-07-07 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* 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
often slower than files in the filesystem, and so memory mapping
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.
2008-07-03 Bob Friesenhahn <bfriesen@simple.dallas.tx.us>
* www/GraphicsMagick.html: Improved formatting of documentation.
