86 % ImportQuantumPixels() transfers one or more pixel components from a user
87 % supplied buffer into the image pixel cache of an image. The pixels are
88 % expected in network byte order. It returns MagickTrue if the pixels are
89 % successfully transferred, otherwise MagickFalse.
90 %
91 % The format of the ImportQuantumPixels method is:
92 %
93 % size_t ImportQuantumPixels(const Image *image,CacheView *image_view,
94 % QuantumInfo *quantum_info,const QuantumType quantum_type,
95 % const unsigned char *magick_restrict pixels,ExceptionInfo *exception)
96 %
97 % A description of each parameter follows:
98 %
99 % o image: the image.
100 %
101 % o image_view: the image cache view.
102 %
103 % o quantum_info: the quantum info.
104 %
105 % o quantum_type: Declare which pixel components to transfer (red, green,
106 % blue, opacity, RGB, or RGBA).
107 %
108 % o pixels: The pixel components are transferred from this buffer.
109 %
110 % o exception: return any errors or warnings in this structure.
