\subsubsection{Image}
The \var{Image} structure represents an ImageMagick 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.

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 ``pixel cache''. 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.

There are three means of accessing pixel views.  When using the
default view, the pixels are made visible and accessable by using the
AcquireImagePixels() method which provides access to a specified region of
the image.  If you intend to change any of the pixel values, use
GetImagePixels().  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.

A more flexible interface to the image pixels is via the CacheView
interface. This interface supports multiple pixel cache views (limited
by the number of image rows), 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, GetCacheView() to access an
existing pixel region, SetCacheView() to define a new pixel region, 
and SyncCacheView() to save the updated pixel region. The function
GetCacheViewIndexes() provides access to the colormap indexes associated
with the pixel view.

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 ImageMagick'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 PushImagePixels(). Pixel components may be transferred from the
default view into a user-supplied buffer by using PopImagePixels(). Use
of this high-level interface helps protect image coders from changes to
ImageMagick's pixel representation and simplifies the implementation.

to the methods AllocateImage(), AnimateImages(), BlobToImage(), 
CloneAnnotateInfo(), DisplayImages(), GetAnnotateInfo(), ImageToBlob(), 
PingImage(), ReadImage(), ReadImages(), and WriteImage().  These methods
update information in ImageInfo to reflect attributes of the current
image.

Use CloneImageInfo() to duplicate an existing ImageInfo structure
or allocate a new one.  Use DestroyImageInfo() to deallocate memory
associated with an ImageInfo structure.  Use GetImageInfo() to initialize
an existing ImageInfo structure.  Use SetImageInfo() to set image type
information in the ImageInfo structure based on an existing image.

\subsubsection{MagickInfo}
The MagickInfo structure is used by ImageMagick to register support
for an Image format. The MagickInfo structure is allocated with default
parameters by calling SetMagickInfo(). Image formats are registered by
calling RegisterMagickInfo() which adds the initial structure to a linked
list (at which point it is owned by the list). A pointer to the structure
describing a format may be obtained by calling GetMagickInfo(). Pass the
argument NULL to obtain the first member of this list. A human-readable
list of registered image formats may be printed to a file descriptor by
calling ListMagickInfo().

Support for formats may be provided as a module which is part of the
ImageMagick library, provided by a module which is loaded dynamically at
run-time, or directly by the linked program. Users of ImageMagick will
normally want to create a loadable-module, or support encode/decode of
an image format directly from within their program.

\subsubsection{PixelPacket}
The PixelPacket structure is used to represent DirectClass color
pixels in ImageMagick. If the image is indicated as a PseudoClass
image, its DirectClass representation is only valid immediately
after calling SyncImage(). If an image is set as PseudoClass and the
DirectClass representation is modified, the image should then be set as
DirectClass. Use QuantizeImage() to restore the PseudoClass colormap if
the DirectClass representation is modified.

The members of the PixelPacket structure are shown in the following table:

\end{longtable}

\subsubsection{ColorspaceType}
The ColorspaceType enumeration is used to specify the colorspace that
quantization (color reduction and mapping) is done under or to specify
the colorspace when encoding an output image. Colorspaces are ways of
describing colors to fit the requirements of a particular application
 (e.g. Television, offset printing,  color monitors).  Color reduction,  by
default, takes place in the RGBColorspace. Empirical evidence suggests
that distances in color spaces such as YUVColorspace or YIQColorspace
correspond to perceptual color differences more closely han do distances
in RGB space. These color spaces may give better results when color
reducing an image. Refer to quantize for more details.

When encoding an output image, the colorspaces RGBColorspace, 
CMYKColorspace, and GRAYColorspace may be specified. The CMYKColorspace
option is only applicable when writing TIFF, JPEG,  and Adobe Photoshop
bitmap (PSD) files.

\subsubsection{CompositeOperator}
CompositeOperator is used to select the image composition algorithm used to
compose a composite image with an image. By default, each of the composite
mage pixels are replaced by the corresponding image tile pixel. Specify
CompositeOperator to select a different algorithm.

\endhead
UndefinedCompositeOp & Unset value. \\
OverCompositeOp & The result is the union of the the two image shapes with the
composite image obscuring image in the region of overlap. \\
InCompositeOp & The result is a simply composite image cut by the shape of
image. None of the image data of image is included in the result. \\
OutCompositeOp & The resulting image is composite image with the shape of
image cut out. \\
AtopCompositeOp & The result is the same shape as image image, with composite
image obscuring image there the image shapes overlap. Note that this differs
from OverCompositeOp because the portion of composite image outside of image's
shape does not appear in the result. \\
XorCompositeOp & The result is the image data from both composite image and
image that is outside the overlap region. The overlap region will be blank. \\
PlusCompositeOp & The result is just the sum of the  image data. Output values
are cropped to 255 (no overflow). This operation is independent of the matte
channels. \\
MinusCompositeOp & The result of composite image - image, with overflow
cropped to zero. The matte chanel is ignored (set to 255, full coverage). \\
AddCompositeOp & The result of composite image + image, with overflow wrapping
around (mod 256). \\
SubtractCompositeOp & The result of composite image - image, with underflow 
wrapping around (mod 256). The add and subtract operators can be used to 
perform reverible transformations. \\
DifferenceCompositeOp & The result of abs (composite image - image). This is
useful for comparing two very similar images. \\
MultiplyCompositeOp & The result of image multiplied by composite image. \\
BumpmapCompositeOp & The result of image shaded by composite image. \\
CopyCompositeOp & The resulting image is image replaced with composite
image. Here the matte information is ignored. \\
CopyRedCompositeOp & The resulting image is the red channel in image replaced
with the red channel in composite image. The other channels are copied
untouched. \\
CopyGreenCompositeOp & The resulting image is the green channel in image
replaced with the green channel in composite image. The other channels are
copied untouched. \\
CopyBlueCompositeOp & The resulting image is the blue channel in image
replaced with the blue channel in composite image. The other channels are
copied untouched. \\
CopyOpacityCompositeOp & The resulting image is the opacity channel in image
replaced with the opacity channel in composite image. The other channels
are copied
untouched.  The image compositor requires a matte, or opacity channel in the
image for some operations. This extra channel usually defines a mask which
represents a sort of a cookie-cutter for the image. This is the case when
matte is 255 (full coverage) for pixels inside the shape, zero outside,  and
between zero and 255 on the boundary.  For certain operations, if image does
not have a matte channel, it is initialized with 0 for any pixel matching in
color to pixel location (0, 0), otherwise 255 (to work properly borderWidth
must be 0). \\
\end{longtable}

\subsubsection{CompressionType}
CompressionType is used to express the desired compression type when
encoding an image. Be aware that most image types only support a sub-set
of the available compression types. If the compression type specified
is incompatable with the image, ImageMagick selects a compression type
compatable with the image type.

\subsubsection{FilterTypes}
FilterTypes is used to adjust the filter algorithm used when resizing
images. Different filters experience varying degrees of success with
various images and can take signicantly different amounts of processing
time. ImageMagick uses the Lanczos filter by default since this filter has
been shown to provide the best results for most images in a reasonable
amount of time. Other filter types (e.g. TriangleFilter) may execute
much faster but may show artifacts when the image is re-sized or around
diagonal lines. The only way to be sure is to test the filter with
sample images.

\subsubsection{GravityType}
GravityType specifies positioning of an object (e.g. text, image)
within a bounding region (e.g. an image). Gravity provides a convenient
way to locate objects irrespective of the size of the bounding region, 
in other words, you don't need to provide absolute coordinates in order
to position an object. A common default for gravity is NorthWestGravity.

\subsubsection{InterlaceType}
InterlaceType specifies the ordering of the red, green,  and blue pixel
information in the image. Interlacing is usually used to make image
information available to the user faster by taking advantage of the
space vs time tradeoff. For example, interlacing allows images on the
Web to be recognizable sooner and satellite images to accumulate/render
with image resolution increasing over time.

Use LineInterlace or PlaneInterlace to create an interlaced GIF or
progressive JPEG image.

\subsubsection{ProfileType}
Profiles can be embedded in an image file by digital cameras and by
image processing software.  ImageMagick recognizes the profiles listed
here, and also stores other profiles found in images as ``generic'' profiles.

\end{longtable}

\subsubsection{RenderingIntent}
Rendering intent is a concept defined by ICC Spec ICC.1:1998-09, ``File
Format for Color Profiles''. ImageMagick uses RenderingIntent in order
to support ICC Color Profiles.

From the specification: ``Rendering intent specifies the style of
reproduction to be used during the evaluation of this profile in
a sequence of profiles. It applies specifically to that profile in
the sequence and not to the entire sequence. Typically, the user or
application will set the rendering intent dynamically at runtime or
embedding time.''
