10.1.2 Parameter format
The parameter format of the geometry command depends on the value set in the D field of GMDR0.
When the D field is “00”, all parameters are handled in the floating-point format. When the D field is “01”,
colors are handled as the packed RGB format, and others are handled as the fixed-point format. When
the D field is “11”, XY is handled as the packed integer format, colors are handled as the packed RGB
format, and others are handled as the fixed-point format.
In the following text, the floating-point format is suffixed by .float, the fixed point format is suffixed
by .fixed, and the integer format is suffixed by .int. Set GMDR0 properly to match parameter
suffixes.
Rendering command parameters conform to the MB86290A data format.
