85% ExportQuantumPixels() transfers one or more pixel components from the image
86% pixel cache to a user supplied buffer. The pixels are returned in network
87% byte order. It returns the number of exported pixels.
88%
89% The format of the ExportQuantumPixels method is:
90%
91% size_t ExportQuantumPixels(const Image *image,CacheView *image_view,
92% QuantumInfo *quantum_info,const QuantumType quantum_type,
93% unsigned char *magick_restrict pixels,ExceptionInfo *exception)
94%
95% A description of each parameter follows:
96%
97% o image: the image.
98%
99% o image_view: the image cache view.
100%
101% o quantum_info: the quantum info.
102%
103% o quantum_type: Declare which pixel components to transfer (RGB, RGBA,
104% etc).
105%
106% o pixels: The components are transferred to this buffer.
107%
108% o exception: return any errors or warnings in this structure.
