In bbuchsbaum/colorplane: Basic S4 Classes and Methods for Mapping Between Numeric Values and Colors
RGBColorPlane-class R Documentation
RGBColorPlane
Description
RGBColorPlane constructor taking a 3- or 4-column numeric matrix of RGB(A) colors in the 0-255 range.
Usage
RGBColorPlane(clr)
Arguments
clr
a matrix of colors where the first column is red, second column is green, third column is blue, and optional fourth column is alpha.
Value
a new RGBColorPlane instance
Examples
rgba_cmat <- rbind(c(255,0,0,255),
c(0, 255, 0, 255),
c(0, 0, 255, 0))
cp <- RGBColorPlane(rgba_cmat)
stopifnot(all(cp@clr[1,] == c(255,0,0,255)))
