Examples


#this is tautological, but demonstrates the syntax...
library(rtiff)
tif <- readTiff(paste(.path.package("rtiff"), "/tiff/jello.tif", sep=""))
myPixmap <- newPixmapRGB(tif@red, tif@green, tif@blue)
plot(myPixmap)

#let's scramble the color channels just for fun

get(getOption("device"))()
myPixmap <- newPixmapRGB(tif@blue, tif@red, tif@green)
plot(myPixmap)
