Loading a shading image out of the camera
GPDATA_BUFFER is used to load a shading image out of the camera. Because
the size of a shading image is larger than GPDATA_BUFFER, input must be
handled in several steps: It is recommended that block reads are used to read
a block of n bytes with one command out of the GPDATA_BUFFER. With firm-
ware 3.03 it is possible to read quadlets directly out of the buffer, but this
takes much more time.
