pxlmap(3G)pxlmap(3G)NAME
pxlmap - define pixel transfer LUTs
FORTRAN SPECIFICATION
subroutine pxlmap(map, size, values)
PARAMETERS
map specifies a symbolic map name. Must be one of the following:
MAP_I_TO_I,
MAP_I_TO_R, MAP_I_TO_G, MAP_I_TO_B, MAP_I_TO_A,
MAP_R_TO_R, MAP_G_TO_G, MAP_B_TO_B, MAP_A_TO_A
size expects the size of the map, valid sizes are 256 or 4096.
values
the LUT itself.
DESCRIPTION
The operation of lrectwrite and rectcopy can be mapped through lookup
tables. The function pixeltransfer() enables this functionality. The
function pixelmap() defines the lookup tables. The source pixels in the
range [0.,1.] map into the range [0.,size). Each entry in the table is
16 bits, where full intensity is 0xffff and no intensity is 0x0.
SEE ALSO
pixelmap,pixeltransfer,convolve
NOTES
pixelmap only works on RealityEngine systems running 5.0.1 or greater.
It requires that the pixelzoom factors are both 1.0.
