85% ImportQuantumPixels() transfers one or more pixel components from a user
86% supplied buffer into the image pixel cache of an image. The pixels are
87% expected in network byte order. It returns the number of imported pixels.
88%
89% The format of the ImportQuantumPixels method is:
90%
91% size_t ImportQuantumPixels(const Image *image,CacheView *image_view,
92% QuantumInfo *quantum_info,const QuantumType quantum_type,
93% const 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 (red, green,
104% blue, opacity, RGB, or RGBA).
105%
106% o pixels: The pixel components are transferred from this buffer.
107%
108% o exception: return any errors or warnings in this structure.
