% 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(Image *image,CacheView *image_view,
% const 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.
