% ExportQuantumPixels() transfers one or more pixel components from the image
% pixel cache to a user supplied buffer. The pixels are returned in network
% byte order. MagickTrue is returned if the pixels are successfully
% transferred, otherwise MagickFalse.
%
% The format of the ExportQuantumPixels method is:
%
% size_t ExportQuantumPixels(const Image *image,
% const CacheView *image_view,const QuantumInfo *quantum_info,
% const QuantumType quantum_type,unsigned char *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 (RGB, RGBA,
% etc).
%
% o pixels: The components are transferred to this buffer.
%
% o exception: return any errors or warnings in this structure.
%
