% AcquireImagePixels() returns an immutable pixel region. If the
% region is successfully accessed, a pointer to it is returned, otherwise
% NULL is returned. The returned pointer may point to a temporary working
% copy of the pixels or it may point to the original pixels in memory.
% Performance is maximized if the selected region is part of one row, or one
% or more full rows, since there is opportunity to access the pixels in-place
% (without a copy) if the image is in RAM, or in a memory-mapped file. The
% returned pointer should *never* be deallocated by the user.
%
% Pixels accessed via the returned pointer represent a simple array of type
% PixelPacket. If the image type is CMYK or the storage class is PseudoClass,
% call GetAuthenticIndexQueue() after invoking GetAuthenticPixels() to access
% the black color component or to obtain the colormap indexes (of type
% IndexPacket) corresponding to the region.
%
% If you plan to modify the pixels, use GetAuthenticPixels() instead.
%

% thread-safe. In a threaded environment, use GetCacheViewVirtualPixels() or
% GetCacheViewAuthenticPixels() instead.

% SetImagePixels() queues a mutable pixel region.
% If the region is successfully initialized a pointer to a PixelPacket
% array representing the region is returned, otherwise NULL is returned.
% The returned pointer may point to a temporary working buffer for the
% pixels or it may point to the final location of the pixels in memory.
%
% Write-only access means that any existing pixel values corresponding to
% the region are ignored. This useful while the initial image is being
% created from scratch, or if the existing pixel values are to be
% completely replaced without need to refer to their pre-existing values.
% The application is free to read and write the pixel buffer returned by
% SetImagePixels() any way it pleases. SetImagePixels() does not initialize
% the pixel array values. Initializing pixel array values is the
% application's responsibility.
%
% Performance is maximized if the selected region is part of one row, or
% one or more full rows, since then there is opportunity to access the
% pixels in-place (without a copy) if the image is in RAM, or in a
% memory-mapped file. The returned pointer should *never* be deallocated
% by the user.
%
% Pixels accessed via the returned pointer represent a simple array of type
% PixelPacket. If the image type is CMYK or the storage class is PseudoClass,
% call GetAuthenticIndexQueue() after invoking GetAuthenticPixels() to obtain
% the black color component or the colormap indexes (of type IndexPacket)
% corresponding to the region. Once the PixelPacket (and/or IndexPacket)
% array has been updated, the changes must be saved back to the underlying
% image using SyncAuthenticPixels() or they may be lost.

% ZoomImage() creates a new image that is a scaled size of an existing one.

% Triangle is equivalent to bi-linear interpolation, and Mitchel giver slower,
% very high-quality results. See Graphic Gems III for details on this
% algorithm.
