In R, readed in the help(rasterImage):

require(grDevices)
#set up the plot region:
op <- par(bg = "thistle") 
plot(c(100, 250), c(300, 450), type = "n", xlab="", ylab="")
image <- as.raster(matrix(0:1, ncol=5, nrow=3))
rasterImage(image, 100, 300, 150, 350, interpolate=FALSE)
rasterImage(image, 100, 400, 150, 450)
rasterImage(image, 200, 300, 200 + xinch(.5), 300 + yinch(.3), interpolate=FALSE)
rasterImage(image, 200, 400, 250, 450, angle=15, interpolate=FALSE)
par(op)

....is a nice example.
