ImageMagick Studio LLC announces the release of ImageMagick 6.6.4-7. This
release focuses on bug fixes, performance improvements, improved quality
of image distortions, and improve support of the PSD image format. To download
ImageMagick, go to

http://www.imagemagick.org.
ImageMagick® is a software suite to create, edit, and compose bitmap images.
It can read, convert and write images in a variety of formats (over 100)
including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG,
and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and
transform images, adjust image colors, apply various special effects, or draw
text, lines, polygons, ellipses and Bézier curves.
The functionality of ImageMagick is typically utilized from the command line
or you can use the features from programs written in your favorite programming
language. Choose from these interfaces: G2F (Ada), MagickCore (C), MagickWand
(C), ChMagick (Ch), ImageMagickObject (COM ), Magick (C ), JMagick (Java),
L-Magick (Lisp), NMagick (Neko/haXe), MagickNet (.NET), PascalMagick (Pascal),
PerlMagick (Perl), MagickWand for PHP (PHP), IMagick (PHP), PythonMagick
(Python), RMagick (Ruby), or TclMagick (Tcl/TK). With a language interface,
use ImageMagick to modify or create images dynamically and automagically.
ImageMagick is free software delivered as a ready-to-run binary distribution
or as source code that you may freely use, copy, modify, and distribute in
both open and proprietary applications. It is distributed under an Apache
2.0-style license, approved by the OSI and recommended for use by the OSSCC.
The ImageMagick development process ensures a stable API and ABI. Before each
ImageMagick release, we perform a comprehensive security assessment that
includes memory and thread error detection to prevent security
vulnerabilities.
Features and Capabilities
Here are just a few examples of what ImageMagick can do:
* Format conversion: convert an image from one format to another (e.g. PNG
to JPEG).
* Transform: resize, rotate, crop, flip or trim an image.
* Transparency: render portions of an image invisible.
* Draw: add shapes or text to an image.
* Decorate: add a border or frame to an image.
* Special effects: blur, sharpen, threshold, or tint an image.
* Animation: create a GIF animation sequence from a group of images.
* Text & comments: insert descriptive or artistic text in an image.
* Image identification: describe the format and attributes of an image.
* Composite: overlap one image over another.
* Montage: juxtapose image thumbnails on an image canvas.
* Generalized pixel distortion: correct for, or induce image distortions
including perspective.
* Morphology of shapes: extract features, describe shapes and recognize
patterns in images.
* Motion picture support: read and write the common image formats used in
digital film work.
* Image calculator: apply a mathematical expression to an image or image
channels.
* Discrete Fourier transform: implements the forward and inverse DFT.
* High dynamic-range images: accurately represent the wide range of
intensity levels found in real scenes ranging from the brightest direct
sunlight to the deepest darkest shadows.
* Encipher or decipher an image: convert ordinary images into
* unintelligible gibberish and back again.
* Virtual pixel support: convenient access to pixels outside the image
region.
* Large image support: read, process, or write mega-, giga-, or tera-pixel
image sizes.
* Threads of execution support: ImageMagick is thread safe and most
internal algorithms are OpenMP-enabled to take advantage of speed-ups
offered by multicore processor chips.
* Heterogeneous distributed processing: certain algorithms are
OpenCL-enabled to take advantage of speed-ups offered by executing in
concert across heterogeneous platforms consisting of CPUs, GPUs, and
other processors.
* ImageMagick on the iPhone: convert, edit, or compose images on your
iPhone.
Examples of ImageMagick Usage, http://www.imagemagick.org/Usage/,
shows how to use ImageMagick from the command-line to accomplish any
of these tasks and much more. Also, see Fred's ImageMagick Scripts,
http://www.fmwconcepts.com/imagemagick/, a plethora of command-line scripts
that perform geometric transforms, blurs, sharpens, edging, noise removal,
and color manipulations.
Significant changes since the last official ImageMagick release, include:
2010-09-27 6.6.4-8 Nicolas Robidoux <nicolas.robidoux< at >gmail...>
* Simplified the ClampUpAxes code, the use of its outputs, its
comments, and credited Craig DeForest for the "clamp singular values"
idea.
* No reason to have "insane" precision Sinc in resize.c: Use
the 1.2e-12 max. abs. relative error version for Q64 as well as Q32.
2010-09-27 6.6.4-8 Anthony Thyssen <A.Thyssen< at >griffith...>
* Replace the blurry "High Quality EWA" technique with a 'Clamped EWA'
for Distort Resampling. This makes -distort a whole lot nicer
and allows for the use of better cylindrical filters.
2010-09-26 6.6.4-7 Anthony Thyssen <A.Thyssen< at >griffith...>
* Fix Point filter for ResizeImage() caused by support limiting the
Box weighting function.
2010-09-26 6.6.4-6 Cristy <quetzlzacatenango< at >image...>
* Don't allow resize filter weights to go to zero (reference
http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17132).
2010-09-24 6.6.4-6 Nicolas Robidoux <nicolas.robidoux< at >gmail...>
* Now that MagickPIL is a MagickRealType, some casts are unneeded.
2010-09-21 6.6.4-6 Cristy <quetzlzacatenango< at >image...>
* Do not break words if caption size is absolute (reference
http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=17123).
* Don't define HAVE_THREADS for --without-threads configure script option.
2010-09-20 6.6.4-5 Nicolas Robidoux <nicolas.robidoux< at >gmail...>
* Modified "magick/resize.c" so that MagickPIL is a MagickRealType number.
Some computations were needlessly done in long double precision because
PIL forced an automatic upcast wherever it appeared. Changed its name to
MagickREALTYPEPI. <- This was later reverted back to MagickPIL.
* Modified "magick/resize.c" so that Bohman uses one trig call one sqrt
call instead of two trig calls.
2010-09-20 6.6.4-5 Anthony Thyssen <A.Thyssen< at >griffith...>
* modified "magick/resample.c" to allow use of either EWA or HQEWA (default)
* Removed LanczosFast from supported filters (SincFast*SincFast is faster)
2010-09-19 6.6.4-5 Cristy <quetzlzacatenango< at >image...>
* If IPTC profile is not embedded in an 8bim resource, declare it IPTC
rather than 8BIM.
* Support %[version] and %[copyright].
* Improve performance of the pixel cache.
2010-09-18 6.6.4-4 Cristy <quetzlzacatenango< at >image...>
* Automatically set the quantum depth to 16 for HDRI.
2010-09-16 6.6.4-2 Cristy <quetzlzacatenango< at >image...>
* IPTC profile not always wrapped properly inside an 8BIM profile.
* TIFF tile geometry must be divisible by 16.
2010-09-15 6.6.4-2 Anthony Thyssen <A.Thyssen< at >griffith...>
* Rename of SincPolynomial to SincFast for easier user understanding
* Ditto for LanczosChebyshev to LanzcosFast
2010-09-14 6.6.4-2 Anthony Thyssen <A.Thyssen< at >griffith...>
* Switch default resize filters to using the faster SincPolynomial
filter by default internally. However 'Sinc' will still use the
Trigonometric function, and can be used to assign the trig version
of Sinc() to filters using the filter expert options.
* The default filter for 'distort' was found to be a very blurry inaccurate
filter function. It was removed and replaced with a correct Gaussian
filter (as used by resize)
* Added a switch so that "-interpolate filter" will force the use of
a cylindrical filter for ALL pixels in distorted images. That is you can
use that switch to use a cylindrical filter even for images that are
being enlarged by the distortion. However EWA is still currently using
a fixed 2.0 sampling radius. This switch complements the use of "-filter
point" which turns off EWA filters in favor of interpolation for all
pixels in a distorted image. BOTH switches should not be used together.
* A bug in the support radius of the EWA resampling function was found,
now that correctly defined resize filters are being used. Suddenly Normal
Gaussian distortions are not so blurry, and tests with distortions of
the 'Rings' image show extremely good and clear results, with only minimal
blurring. The filter 'blur' expert option can be used to adjust this
further.
The above represents a major improvement forward in the quality of the
image distortion operator. But near-unity distortions (no scaling) are
still overly blurry.
2010-09-13 6.6.4-2 Cristy <quetzlzacatenango< at >image...>
* Don't negate the geometry offset for the -extent option.
2010-09-09 6.6.4-1 Cristy <quetzlzacatenango< at >image...>
* The RGBO format is now listed as a supported format.
2010-09-07 6.6.4-1 Anthony Thyssen <A.Thyssen< at >griffith...>
* Added the Nicolas Robidoux and Chantal Racette Lanczos resize filter
function as "LanczosChebyshev" as faster alternative to Lanczos.
* Re-code Nicolas Robidoux and Chantal Racette Polynomial Approximation of
the Sinc Trigonometric resize filter, as a proper filter to allow
direct comparision and speed testing of the filter.
* Expanded the "-set option:filter:verbose 1" output, so as to also include
the actual functions and other values that were used to create the filter.
2010-09-02 6.6.4-0 el_supremo <digipete< at >shaw...>
* Repair a few incorrect LocaleNCompare() calls (ttf.c, ps.c).
2010-08-31 6.6.4-0 Cristy <quetzlzacatenango< at >image...>

2010-07-25 6.6.3-1 Glenn Randers-Pehrson <glennrp< at >image...>
* Don't "ping" a PNG image if it is embedded in a MNG. Otherwise the

2010-07-07 6.6.3-1 Glenn Randers-Pehrson <glennrp< at >image...>
* The PNG decoder failed to handle the tRNS chunk properly for grayscale
images where the png bit_depth was not the same as the quantum depth,
and the transparent color was not black.
2010-07-01 6.6.3-0 Chris Madison <madisonblu< at >gmail...>
* Pinging the DJVU image format no longer faults.
* Check for time-limit-exceeded in only one thread.
* Reading filenames from a file (e.g. < at >filenames) no longer includes the

* Ensure the set option deletes the image artifact.
2010-05-28 6.6.2-1 Glenn Randers-Pehrson <glennrp< at >image...>
* Prevent coders/png.c from attempting to write an empty tRNS chunk.
2010-05-25 6.6.2-1 Anthony Thyssen <A.Thyssen< at >griffith...>
* Fix for Square Array Rotates (off center origin rotate)
* Added HitAndMiss kernel Ridges2 to find 2 pixel thick ridges
* Added FreiChen:0,{angle} FreiChen:{angle} and FreiChen:-1 variations
to complete this kernels definition
2010-05-24 6.6.2-1 Cristy <quetzlzacatenango< at >image...>
* Respect density when rendering SVG images.

2010-05-23 6.6.2-0 Anthony Thyssen <A.Thyssen< at >griffith...>
* Third Re-write of MorphologyApply() to better handle compound methods.
* Implemented -set option:morphology:compose for merging results of
multiple kernels. "None" means re-iterate results with next kernel.
While "Undefined" means to use the internal default for a method.
Thinning, Thickening, HitAndMiss, Convolve, Correlate defaults to "None"
while HitAndMiss defaults to "Lighten" (union of all kernel results).
Other morphology methods defaults still to be decided.
* Added HitAndMiss Kernel: Ridges (find ridges and pixel width lines)
* Rotation Expansion of single kernels '^' and '< at >' flags in arguments
EG: -set option:showkernel 1 -morphology Convolve 'Blur:0x2^'
* ExpandKernelInfo() (rotation expand) now groks symmetrical kernels.
So the above will only produce a list of 2 kernels, not 4 kernels
2010-05-18 6.6.2-0 Anthony Thyssen <A.Thyssen< at >griffith...>
* Separation of internal function MorphologyApply() from
MorphologyImageChannel() to calls to convolve without user settings.

* Better handling of Gaussian tyle filters (bug fixes)
* Bug fix and optimization of kernel size calculations in "gem.c"
* Allow '^' or '< at >' flags in 'user defined' kernel size arguments to
expand kernel into a rotated list.
EG: -set option:showkernel 1 -morphology Thinning '3< at >: 0,1,0 0,1,0 0,0,0'
* Allow a scaled unity kernel to be added to kernel (EdgeDet->Sharpen)
EG: -set option:convolve:scale [kernel_scale][^!],[unity_scale][%]
* Addition of "Laplacian of Gaussian" (LOG), also known as Mexican Hat
EG: -morphology convolve LOG:0x1
* Added FreiChen, Kirsch Convolution kernels
* Added Descrete 'Laplacian of Gaussian' kernels (Laplacian type 15 and 19)

2010-05-17 6.6.2-0 Cristy <quetzlzacatenango< at >image...>
* PSD images require a proper layer to support an alpha channel.
* Enable PFM endian support.
* Add context to -border for montage. Inside the parenthesis it adds a border
to the image otherwise it sets the border for the layout manager.
* 24-bit BMP images are not colormapped even if header colors != 0.
* Set DPX user data like this: -set profile dpx:userdata.txt.
* Make sure Lab => RGB => Lab survives the round trip.
2010-05-15 6.6.1-10 Cristy <quetzlzacatenango< at >image...>
* Use ScaleCharToQuantum() in coders/src.c (reference

2010-05-14 6.6.1-9 Anthony Thyssen <A.Thyssen< at >griffith...>
* Addition of more Morphological/Convolution Kernels.
DOG (Difference of Gaussians) and DOB (Difference of Blurs),
EG: -morphology convolve DOG:0x1,3
-morphology convolve DOB:0x1,3,90
* Added Prewitt, Roberts, Compass Convolution Kernels
* Ring Symbol Kernel (subtraction of Disk from a Disk)
2010-05-13 6.6.1-9 Cristy <quetzlzacatenango< at >image...>
* The pixel buffer was underallocated for some image formats when streaming.
2010-05-12 6.6.1-8 Anthony Thyssen <A.Thyssen< at >griffith...>
* Implementation of Pattern Matching Morphology methods
HitAndMiss, Thicken, Thinning
* Reporting of Kernel Strings that fail to parse (though not why)
* Parsing of Multiple Kernel Strings, generating a list of kernels
* Union of results from Multiple Kernels for HitAndMiss method
* Interated Multiple Kernels for all other morphology methods
* Added many new kernels for HitAndMiss and Convolution
Sobel, Laplacian, Cross, Peaks, Corners, LineEnds, LineJunctions,
ConvexHull (for Thicken), Skeleton (for Thinning)
2010-05-08 6.6.1-8 Glenn Randers-Pehrson <glennrp< at >image...>
* Use proper background.index when writing indexed PNG, if the background
color is in the palette.
2010-05-08 6.6.1-7 Cristy <quetzlzacatenango< at >image...>
* Fix improper 'invalid colormap index' PNG bug.
* Fix PerlMagick compile exception.
2010-05-07 6.6.1-6 Anthony Thyssen <A.Thyssen< at >griffith...>
* Added % and ! modification flags to morphology distance kernel
scaling factor, for easier usage.
* Bug fix for compose math channel handling and morphology diff usage
2010-05-06 6.6.1-6 Cristy <quetzlzacatenango< at >image...>
* Do not claim gray colorspace if gray image includes a non-gray pixel.
* Initialize BMP alpha channel to opaque for RGB images.
* Fixed under allocation for round rectangles.
* The -list option returns a 0 status as expected.
2010-05-06 6.6.1-6 Anthony Thyssen <A.Thyssen< at >griffith...>
* Made use of new no-'sync' channel enabled mathematical compose methods
for the difference morphology methods. These should now work correctly
for specific channels, and more importantly for alpha shaped morphology.
2010-05-05 6.6.1-6 Glenn Randers-Pehrson <glennrp< at >image...>
* Fixed bugs with losing the opacity channel while writing some PNG images.
(bug reported by Anthony T.)
2010-05-05 6.6.1-6 Glenn Randers-Pehrson <glennrp< at >image...>
* Simplified and corrected rowbytes calculation in coders/png.c and
added more logging.
2010-05-05 6.6.1-6 Anthony Thyssen <A.Thyssen< at >griffith...>
* Rename of "Add" and "Subtract" compositions to "ModulusAdd" and
"ModulusSubtract" for more clarity of there functions. Old names
will continue to work as expected.
* Fix "Minus", "ModulusAdd", and "ModulusSubtract" to follow
normal SVG 'Over' blending specifications, (see next for override)
Note that this does NOT include the "Plus" composition method which has
SVG definition for it to use a 'Plus' blending rather than 'Over' blending.
* By default mathematical compositions work as per SVG definition. That is
the results are synchronized with 'Over' alpha-blending (except "Plus"
which uses 'plus' alpha-blending).
By removing the default 'sync' flag from the -channel setting however
Break this inter-channel synchronization and do the mathematical operations
only on the individual channels as specified by the -channel setting.
That is do 'channel' math rather than 'SVG' composition.
With this change you can then use mathematical composition methods on
individual channels or even with the alpha channel of images.
2010-04-28 6.6.1-6 Anthony Thyssen <A.Thyssen< at >griffith...>
* Special case handling in Barrel distortion (pixel at image center)
* Calculation of image for Barrel distortion (pixel vs image coords)
* Argument input (handling optional 'd' argument) for Barrel distortion
2010-04-24 6.6.1-6 Cristy <quetzlzacatenango< at >image...>
* Do not declare timestruct under MinGW.
* Respect -compose option for the montage utility (bug report by Anthony).
* A 256 column gradient produces a 256 color GIF image (bug report by
Anthony).
* Register / unregister CALS format in static.c (reference
http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=16103).
* Add SetImageColor() method.
2010-04-17 6.6.1-5 Cristy <quetzlzacatenango< at >image...>

ImageMagick Studio LLC announces the release of ImageMagick 6.6.0-1. This
release focuses on bug fixes, performance improvements, and new features
such as the -morphology option. To download ImageMagick, go to
http://www.imagemagick.org.
... [More]
ImageMagick® is a software suite to create, edit, and compose bitmap
images. It can read, convert and write images in a variety of formats (over
100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript,
SVG, and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale,
shear and transform images, adjust image colors, apply various special effects,
or draw text, lines, polygons, ellipses and Bézier curves.
The functionality of ImageMagick is typically utilized from the command line
or you can use the features from programs written in your favorite programming
language. Choose from these interfaces: G2F (Ada), MagickCore (C), MagickWand
(C), ChMagick (Ch), ImageMagickObject (COM+), Magick++ (C++), JMagick (Java),
L-Magick (Lisp), NMagick (Neko/haXe), MagickNet (.NET), PascalMagick (Pascal),
PerlMagick (Perl), MagickWand for PHP (PHP), IMagick (PHP), PythonMagick
(Python), RMagick (Ruby), or TclMagick (Tcl/TK). With a language interface,
use ImageMagick to modify or create images dynamically and automagically.
ImageMagick is free software delivered as a ready-to-run binary distribution
or as source code that you may freely use, copy, modify, and distribute. Its
license is compatible with the GPL. It runs on all major operating systems.
Features and Capabilities
Here are just a few examples of what ImageMagick can do:
* Format conversion: convert an image from one format to another (e.g.
PNG to JPEG).
* Transform: resize, rotate, crop, flip or trim an image.
* Transparency: render portions of an image invisible.
* Draw: add shapes or text to an image.
* Decorate: add a border or frame to an image.
* Special effects: blur, sharpen, threshold, or tint an image.
* Animation: create a GIF animation sequence from a group of images.
* Text & comments: insert descriptive or artistic text in an image.
* Image identification: describe the format and properties of an image.
* Composite: overlap one image over another.
* Montage: juxtapose image thumbnails on an image canvas.
* Motion picture support: read and write the common image formats used in
digital film work.
* Image calculator: apply a mathematical expression to an image or image
channels.
* Discrete Fourier transform: implements the forward and inverse DFT.
* High dynamic-range images: accurately represent the wide range of
intensity levels found in real scenes ranging from the brightest direct
sunlight to the deepest darkest shadows.
* Encipher or decipher an image: convert ordinary images into
unintelligible gibberish and back again.
* Virtual pixel support: convenient access to pixels outside the image
region.
* Large image support: read, process, or write mega-, giga-, or
tera-pixel image sizes.
* Threads of execution support: ImageMagick is thread safe and most
internal algorithms are OpenMP-enabled to take advantage of speed-ups
offered by the dual and quad-core processor technologies.
* Heterogeneous distributed processing: certain algorithms are
OpenCL-enabled to take advantage of speed-ups offered by executing in
concert across heterogeneous platforms consisting of CPUs, GPUs, and
other processors.
Examples of ImageMagick Usage, http://www.imagemagick.org/Usage/,
shows how to use ImageMagick from the command-line to accomplish any
of these tasks and much more. Also, see Fred's ImageMagick Scripts,
http://www.fmwconcepts.com/imagemagick/, a plethora of command-line scripts
that perform geometric transforms, blurs, sharpens, edging, noise removal,
and color manipulations.
Significant changes since the last official ImageMagick release, include:
2010-02-27 6.6.0-1 Cristy <quetzlzacatenango< at >image...>
* Check to see if ICON image width /height exceeds that of the image
canvas.
* Set the DPX descriptor to Luma only if the image type is not TrueColor.
* Add support for the Adobe Large Document format.
* Add support for -fx airy(), j0(), j1(), jinc(), and sinc() (reference
viewtopic.php?f=2&t=15685).
* Don't embed an XMP profile in an EPS image for now.
2010-02-21 6.6.0-0 Cristy <quetzlzacatenango< at >image...>
* Insufficient image data in EPT is a warning rather than an error.
* Respect -type TrueColor when writing gray DPX images.
* Fix problem reading 10-bit grayscale DPX images when scanline length is
not a multiple of 3.
* BMP has an alpha channel, it was treated as an opacity channel.
2010-02-20 6.5.9-10 Cristy <quetzlzacatenango< at >image...>
* Write 10-bit grayscale DPX images properly.
2010-02-18 6.5.9-8 Cristy <quetzlzacatenango< at >image...>
* Detect PDF ICCBased colorspace.
2010-02-18 6.5.9-7 Anthony Thyssen <A.Thyssen< at >griffith...>
* Finalized -set option:convolve:scale kernel normalize/scale option
2010-02-16 6.5.9-7 Cristy <quetzlzacatenango< at >image...>
* TransformImage() resets the image blob when called in the PICT decoder;
use SetImageExtent() instead.
2010-02-14 6.5.9-6 Cristy <quetzlzacatenango< at >image...>
* Support PSD RLE compression.
2010-02-13 6.5.9-5 Cristy <quetzlzacatenango< at >image...>

2010-02-08 6.5.9-3 Anthony Thyssen <A.Thyssen< at >griffith...>
* Added Correlate method which does a Convolve without reflecting the
kernel.
2010-02-07 6.5.9-3 Cristy <quetzlzacatenango< at >image...>
* Initialize grayscale colormap for PSD images.
2010-02-07 6.5.9-3 Anthony Thyssen <A.Thyssen< at >griffith...>
* Final testing and fixing of basic morphology operators
* Addition Third-level Subtractive Morphology Methods: EdgeIn, EdgeOut,
Edge, TopHat, BottomHat
* Ensuring original kernels passed to morphology are cloned before being
modified for use by specific methods (EG: convolve scale/normalize)
2010-02-03 6.5.9-2 Cristy <quetzlzacatenango< at >image...>
* display -immutable to display transparent image without a checkboard.
2010-01-27 6.5.9-1 Glenn Randers-Pehrson <glennrp< at >image...>

* correct use of a 'reflected kernel' for 'Convolve' 'Dilate' and
'Distance' Morphology primitives. This does not have a performance hit,
though is only truely applicable when the kernel is asymmetric. Note
that 'Erode' does not use a 'reflected' kernel, so that 'Open' and
'Close' operations work properly. This 'reflected usage is defined by
online morphology lecture notes (Google for "EECE Binary Morphology")
* Added convolve kernel scaling setting "-set option:convolve:scale N" If
undefined morphology convolve does not do any scaling or normalization
of the convolution kernel. A value of 0.0 causes normalization for
both zero and non-zero (added weights) kernel types.
2010-01-15 6.5.9-1 Cristy <quetzlzacatenango< at >image...>
* Speed up reading the PSD image format.
* Add the -precision option. Use it to set the maximum number of
significant digits to be printed.
* Add -features option to the identify program to display channel
features.
* Add -unique option to the identify program to display channel features.

ImageMagick Studio LLC announces the release of ImageMagick 6.4.5-9.
This release focuses on additional speed improvements including exploiting
multiple cores with the assistance of OpenMP technologies. Some algorithms
perform at a near linear
... [More]
speed-up (given 4 cores we expect the algorithm to
execute nearly four times as fast).
ImageMagick® is a software suite to create, edit, and compose bitmap images.
It can read, convert and write images in a variety of formats (over 100)
including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG,
and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale, shear
and transform images, adjust image colors, apply various special effects,
or draw text, lines, polygons, ellipses and Bézier curves.
The functionality of ImageMagick is typically utilized from the command line
or you can use the features from programs written in your favorite programming
language. Choose from these interfaces: G2F (Ada), MagickCore (C), MagickWand
(C), ChMagick (Ch), ImageMagickObject (COM+), Magick++ (C++), JMagick (Java),
L-Magick (Lisp), NMagick (Neko/haXe), MagickNet (.NET), PascalMagick (Pascal),
PerlMagick (Perl), MagickWand for PHP (PHP), IMagick (PHP), PythonMagick
(Python), RMagick (Ruby), or TclMagick (Tcl/TK). With a language interface,
use ImageMagick to modify or create images dynamically and automagically.
ImageMagick is free software delivered as a ready-to-run binary distribution
or as source code that you may freely use, copy, modify, and distribute. Its
license is compatible with the GPL. It runs on all major operating systems.
Features and Capabilities
Here are just a few examples of what ImageMagick can do:
* Format conversion: convert an image from one format to another (e.g. PNG
to JPEG)
* Transform: resize, rotate, crop, flip or trim an image
* Transparency: render portions of an image invisible
* Draw: add shapes or text to an image
* Decorate: add a border or frame to an image
* Special effects: blur, sharpen, threshold, or tint an image
* Animation: create a GIF animation sequence from a group of images
* Text & comments: insert descriptive or artistic text in an image
* Image identification: describe the format and properties of an image
* Composite: overlap one image over another
* Montage: juxtapose image thumbnails on an image canvas
* Motion picture support: read and write the common image formats used in
digital film work
* Image calculator: apply a mathematical expression to an image or image
channels
* High dynamic-range images: accurately represent the wide range of
intensity levels found in real scenes ranging from the brightest direct
sunlight to the deepest darkest shadows
* Virtual pixel support: convenient access to pixels outside the image
region
* Large image support: read, process, or write mega- and giga-pixel image
sizes
* Encipher or decipher an image: convert ordinary images into
unintelligible gibberish and back again
* Threads of execution support: ImageMagick is thread safe and most
internal algorithms are OpenMP-enabled to take advantage of speed-ups
offered by the dual and quad-core processor technologies
Examples of ImageMagick Usage, http://www.imagemagick.org/Usage/, shows how to use ImageMagick from the command-line to accomplish any of these tasks and much more. Also, see Fred's ImageMagick Scripts, http://www.fmwconcepts.com/imagemagick/, a plethora of command-line scripts that perform geometric transforms, blurs, sharpens, edging, noise removal, and color manipulations.

Introduction to ImageMagick
ImageMagick® is a software suite to create, edit, and compose bitmap images.
It can read, convert and write images in a variety of formats (over 100)
including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG,
and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and
transform images, adjust image colors, apply various special effects, or draw
text, lines, polygons, ellipses and Bézier curves.
The functionality of ImageMagick is typically utilized from the command line
or you can use the features from programs written in your favorite programming
language. Choose from these interfaces: G2F (Ada), MagickCore (C), MagickWand
(C), ChMagick (Ch), ImageMagickObject (COM ), Magick (C ), JMagick (Java),

ImageMagick Studio LLC announces the release of ImageMagick 6.4.1-8.
Introduction to ImageMagick
ImageMagick® is a software suite to create, edit, and compose bitmap
images. It can read, convert and write images in a variety of formats
(over
... [More]
100) including DPX, EXR, GIF, JPEG, JPEG-2000, PDF, PhotoCD, PNG,
Postscript, SVG, and TIFF. Use ImageMagick to translate, flip, mirror,
rotate, scale, shear and transform images, adjust image colors, apply various
special effects, or draw text, lines, polygons, ellipses and Bézier curves.
The functionality of ImageMagick is typically utilized from the command
line or you can use the features from programs written in your favorite
programming language. Choose from these interfaces: G2F (Ada), MagickCore
(C), MagickWand (C), ChMagick (Ch), ImageMagickObject (COM ), Magick
(C ), JMagick (Java), L-Magick (Lisp), NMagick (Neko/haXe), MagickNet
(.NET), PascalMagick (Pascal), PerlMagick (Perl), MagickWand for PHP
(PHP), IMagick (PHP), PythonMagick (Python), RMagick (Ruby), or TclMagick
(Tcl/TK). With a language interface, use ImageMagick to modify or create
images dynamically and automagically.
ImageMagick is free software delivered as a ready-to-run binary distribution
or as source code that you may freely use, copy, modify, and distribute. Its
license is compatible with the GPL. It runs on all major operating systems.
Features and Capabilities
Here are just a few examples of what ImageMagick can do:
* Format conversion: convert an image from one format to another (e.g.
PNG to JPEG)
* Transform: resize, rotate, crop, flip or trim an image
* Transparency: render portions of an image invisible
* Draw: add shapes or text to an image
* Decorate: add a border or frame to an image
* Special effects: blur, sharpen, threshold, or tint an image
* Animation: create a GIF animation sequence from a group of images
* Text & comments: insert descriptive or artistic text in an image
* Image identification: describe the format and properties of an image
* Composite: overlap one image over another
* Montage: juxtapose image thumbnails on an image canvas
* Motion picture support: read and write the common image formats used in
digital film work
* Image calculator: apply a mathematical expression to an image or image
channels
* High dynamic-range images: accurately represent the wide range of
intensity levels found in real scenes ranging from the brightest direct
sunlight to the deepest darkest shadows
* Large image support: read, process, or write mega- and giga-pixel image
sizes
* Encipher or decipher an image: convert ordinary images into
unintelligible gibberish and back again
* Threads of execution support: ImageMagick is thread safe and many
internal algorithms are already threaded to take advantage of speed-ups
offered by the dual and quad-core processor technologies
See http://www.imagemagick.org for more details.
Examples of ImageMagick Usage shows how to use ImageMagick from the
command-line to accomplish any of these tasks and much more. See
http://www.imagemagick.org/Usage/.

ImageMagick Studio LLC announces the release of ImageMagick 6.3.8-2.
ImageMagick® is a software suite to create, edit, and compose bitmap images.
It can read, convert and write images in a variety of formats (over 100)
including DPX, EXR, GIF
... [More]
, JPEG, JPEG-2000, PDF, PhotoCD, PNG, Postscript, SVG,
and TIFF. Use ImageMagick to translate, flip, mirror, rotate, scale, shear and
transform images, adjust image colors, apply various special effects, or draw
text, lines, polygons, ellipses and Béer curves.
The functionality of ImageMagick is typically utilized from the command line
or you can use the features from programs written in your favorite programming
language. Choose from these interfaces: G2F (Ada), MagickCore (C), MagickWand
(C), ChMagick (Ch), ImageMagickObject (COM+), Magick++ (C++), JMagick (Java),
L-Magick (Lisp), NMagick (Neko/haXe), MagickNet (.NET), PascalMagick (Pascal),
PerlMagick (Perl), MagickWand for PHP (PHP), IMagick (PHP), PythonMagick
(Python), RMagick (Ruby), or TclMagick (Tcl/TK). With a language interface,
use ImageMagick to modify or create images dynamically and automagically.
ImageMagick is free software delivered as a ready-to-run binary distribution
or as source code that you may freely use, copy, modify, and distribute. Its
license is compatible with the GPL. It runs on all major operating systems.
Features and Capabilities
Here are just a few examples of what ImageMagick can do:
* Format conversion: convert an image from one format to another (e.g. PNG
to JPEG)
* Transform: resize, rotate, crop, flip or trim an image
* Transparency: render portions of an image invisible
* Draw: add shapes or text to an image
* Decorate: add a border or frame to an image
* Special effects: blur, sharpen, threshold, or tint an image
* Animation: create a GIF animation sequence from a group of images
* Text & comments: insert descriptive or artistic text in an image
* Image identification: describe the format and properties of an image
* Composite: overlap one image over another
* Montage: juxtapose image thumbnails on an image canvas
* Motion picture support: read and write the common image formats used in
digital film work
* Image calculator: apply a mathematical expression to an image or image
channels
* High dynamic-range images: accurately represent the wide range of
intensity levels found in real scenes ranging from the brightest direct
sunlight to the deepest darkest shadows
* Large image support: read, process, or write mega- and giga-pixel image
sizes
* Threads of execution support: ImageMagick is thread safe and many
internal algorithms are already threaded to take advantage of speed-ups
offered by the dual and quad-core processor technologies
Examples of ImageMagick Usage:
http://www.cit.gu.edu.au/~anthony/graphics/imagick6
