+<p>The GraphicsMagick core C library constitutes the implementation of
+GraphicsMagick and provides the lowest-level C language programming
+interface for GraphicsMagick.  The core C API provides many functions
+to read, manipulate, write, or display an image.  To invoke the
+functions, write your program in C (or C++) language while making
+calls to the core library functions and link with libGraphicsMagick.a,
+libGraphicsMagick.so, or GraphicsMagick.dll depending on your system.</p>
+<p>The API is divided into a number of categories. While reading this
+documentation, please reference the <a class="reference external" href="types.html">types</a> documentation as required:</p>

+<p>To compile on Unix, the command would look something like this:</p>
+<pre class="literal-block">
+gcc -o demo demo.c -O `GraphicsMagick-config --cppflags --ldflags --libs`

+<p>As a usage example, with the input files in1.gif, in2.png, and in3.jpg, create
+the animation file out.miff:</p>
+<pre class="literal-block">

+<h2>Description</h2>
+<p>IsImagesEqual() measures the difference between colors at each pixel
+location of two images.  A value other than 0 means the colors match
+exactly.  Otherwise an error measure is computed by summing over all
+pixels in an image the distance squared in RGB space between each image
+pixel and its corresponding pixel in the reference image.  The error
+measure is assigned to these image members:</p>
+<p>o mean_error_per_pixel:  The mean error for any single pixel in
+the image.</p>
+<p>o normalized_mean_error:  The normalized mean quantization error for
+any single pixel in the image.  This distance measure is normalized to
+a range between 0 and 1.  It is independent of the range of red, green,
+and blue values in the image.</p>
+<p>o normalized_maximum_error:  The normalized maximum quantization
+error for any single pixel in the image.  This distance measure is
+normalized to a range between 0 and 1.  It is independent of the range
+of red, green, and blue values in your image.</p>
+<p>A small normalized mean square error, accessed as
+image-&gt;normalized_mean_error, suggests the images are very similiar in
+spatial layout and color.</p>

+<h2>Description</h2>
+<p>ConstituteImage() returns an Image corresponding to an image stored
+in a raw memory array format. The pixel data must be in scanline order
+top-to-bottom. The data can be unsigned char, unsigned short int, unsigned
+int, unsigned long, float, or double.  Float and double require the pixels
+to be normalized to the range [0..1], otherwise the range is [0..MaxVal]
+where MaxVal is the maximum possible value for that type.</p>
+<p>Note that for most 32-bit architectures the size of an unsigned long is
+the same as unsigned int, but for 64-bit architectures observing the LP64
+standard, an unsigned long is 64 bits, while an unsigned int remains 32
+bits. This should be considered when deciding if the data should be
+described as &quot;Integer&quot; or &quot;Long&quot;.</p>
+<p>For example, to create a 640x480 image from unsigned red-green-blue
+character data, use</p>

+<p>DrawPathEllipticArcRelative() draws an elliptical arc from the current
+point to (x, y) using relative coordinates. The size and orientation
+of the ellipse are defined by two radii (rx, ry) and an
+xAxisRotation, which indicates how the ellipse as a whole is rotated
+relative to the current coordinate system. The center (cx, cy) of the
+ellipse is calculated automatically to satisfy the constraints imposed
+by the other parameters. largeArcFlag and sweepFlag contribute to the
+automatic calculations and help determine how the arc is drawn. If
+largeArcFlag is true then draw the larger of the available arcs. If
+sweepFlag is true, then draw the arc matching a clock-wise rotation.</p>

+<h2>Description</h2>
+<p>The HaldClutImage() method apply a color lookup table (Hald CLUT) to the
+image.  The fundamental principle of the Hald CLUT algorithm is that
+application of an identity CLUT causes no change to the input image,
+but an identity CLUT image which has had its colors transformed in
+some way (e.g. in Adobe Photoshop) may be used to implement an identical
+transform on any other image.</p>
+<p>The minimum CLUT level is 2, and the maximum depends on available memory
+(largest successfully tested is 24).  A CLUT image is required to have equal
+width and height. A CLUT of level 8 is an image of dimension 512x512, a CLUT
+of level 16 is an image of dimension 4096x4096.  Interpolation is used so
+extremely large CLUT images are not required.</p>
+<p>GraphicsMagick provides an 'identity' coder which may be used to generate
+identity HLUTs.  For example, reading from &quot;identity:8&quot; creates an identity
+CLUT of order 8.</p>
+<p>The Hald CLUT algorithm has been developed by Eskil Steenberg as described
+at <a class="reference external" href="http://www.quelsolaar.com/technology/clut.html">http://www.quelsolaar.com/technology/clut.html</a>, and was adapted for
+GraphicsMagick by Clément Follet with support from Cédric Lejeune of
+Workflowers.</p>

+<p>MagickMonitorFormatted() calls the monitor handler method with a

+passed are quantum and span values which provide a measure of
+completion.  The method returns MagickPass on success otherwise
+MagickFail if an error is encountered, e.g. if there was a user

+events are reported for every 1% of progress when possible.</p>

+<h2>Description</h2>
+<p>Method RotateImage creates a new image that is a rotated copy of an

+<p>The Image structure represents an GraphicsMagick image. It is initially
+allocated by AllocateImage() and deallocated by DestroyImage(). The
+functions ReadImage(), ReadImages(), BlobToImage() and CreateImage()
+return a new image. Use CloneImage() to copy an image. An image consists
+of a structure containing image attributes as well as the image pixels.</p>
+<p>The image pixels are represented by the structure PixelPacket and are
+cached in-memory, or on disk, depending on the cache threshold setting.
+This cache is known as the &quot;pixel cache&quot;. Pixels in the cache may not be
+edited directly. They must first be made visible from the cache via a
+pixel view. A pixel view is a rectangular view of the pixels as defined
+by a starting coordinate, and a number of rows and columns. When
+considering the varying abilities of multiple platforms, the most
+reliably efficient pixel view is comprized of part, or all, of one image
+row.</p>
+<p>There are two means of accessing pixel views. When using the default
+view, the pixels are made visible and accessable by using the
+GetImagePixels() method which provides access to a specified region of
+the image. After the view has been updated, the pixels may be saved back
+to the cache in their original positions via SyncImagePixels(). In order
+to create an image with new contents, or to blindly overwrite existing
+contents, the method SetImagePixels() is used to reserve a pixel view
+corresponding to a region in the pixel cache. Once the pixel view has
+been updated, it may be written to the cache via SyncImagePixels(). The
+function GetIndexes() provides access to the image colormap, represented
+as an array of type IndexPacket.</p>
+<p>A more flexible interface to the image pixels is via the Cache View
+interface. This interface supports multiple pixel cache views (limited by
+the amount of available memory), each of which are identified by a handle
+(of type ViewInfo). Use OpenCacheView() to obtain a new cache view,
+CloseCacheView() to discard a cache view, GetCacheViewPixels() to access
+an existing pixel region, SetCacheView() to define a new pixel region,
+and SyncCacheViewPixels() to save the updated pixel region. The function
+GetCacheViewIndexes() provides access to the colormap indexes associated
+with the pixel view.</p>
+<p>When writing encoders and decoders for new image formats, it is
+convenient to have a high-level interface available which supports
+converting between external pixel representations and GraphicsMagick's
+own representation. Pixel components (red, green, blue, opacity, RGB, or
+RGBA) may be transferred from a user-supplied buffer into the default
+view by using ImportImagePixelArea(), or from an allocated view via
+ImportViewPixelArea(). Pixel components may be transferred from the
+default view into a user-supplied buffer by using ExportImagePixelArea(),
+or from an allocated view via ExportViewPixelArea(). Use of this
+high-level interface helps protect image coders from changes to
+GraphicsMagick's pixel representation and simplifies the implementation.</p>

+<p>The following shows sample code for a module called &quot;GIF&quot; (gif.c). Note
+that the names of the Register and Unregister call-back routines are
+calculated at run-time, and therefore must follow the rigid naming scheme
+RegisterFORMATImage and UnregisterFORMATImage, respectively, where FORMAT
+is the upper-cased name of the module file:</p>
+<pre class="literal-block">
+/* Read image */
+Image *ReadGIFImage(const ImageInfo *image_info)
+{
+  [ decode the image ... ]
+}
+
+/* Write image */
+unsigned int WriteGIFImage(const ImageInfo *image_info,Image *image)
+{
+  [ encode the image ... ]
+}
+
+/* Module call-back to register support for formats */
+void RegisterGIFImage(void)
+{
+  MagickInfo *entry;
+  entry=SetMagickInfo(&quot;GIF&quot;);
+  entry-&gt;decoder=ReadGIFImage;

+Export void UnregisterGIFImage(void)

+}
+</pre>
+<p>Sample Application Code</p>
+<p>Image format support provided within the user's application does not need
+to implement the RegisterFORMATImage and UnregisterFORMATImage call-back
+routines. Instead, the application takes responsibility for the
+registration itself. An example follows:</p>
+<pre class="literal-block">
+/* Read image */
+Image *ReadGIFImage(const ImageInfo *image_info)
+{
+  [ decode the image ... ]
+}
+/* Write image */

+{
+  [ encode the image ... ]
+}
+#include &lt;stdio.h&gt;
+int main( void )
+{

+  info = SetMagickInfo(&quot;GIF&quot;);
+  if ( info == (MagickInfo*)NULL )

+  info-&gt;decoder = ReadGIFImage;
+  info-&gt;encoder = WriteGIFImage;
