%  ImportQuantumPixels() transfers one or more pixel components from a user
%  supplied buffer into the image pixel cache of an image.  The pixels are
%  expected in network byte order.  It returns MagickTrue if the pixels are
%  successfully transferred, otherwise MagickFalse.
%
%  The format of the ImportQuantumPixels method is:
%
%      size_t ImportQuantumPixels(const Image *image,CacheView *image_view,
%        QuantumInfo *quantum_info,const QuantumType quantum_type,
%        const unsigned char *magick_restrict pixels,ExceptionInfo *exception)
%
%  A description of each parameter follows:
%
%    o image: the image.
%
%    o image_view: the image cache view.
%
%    o quantum_info: the quantum info.
%
%    o quantum_type: Declare which pixel components to transfer (red, green,
%      blue, opacity, RGB, or RGBA).
%
%    o pixels:  The pixel components are transferred from this buffer.
%
%    o exception: return any errors or warnings in this structure.
