Another addition made to ZOOM.DLL (only 2.0x version so far)
Zoom(show=true): prints the calculated values on the screen
CHR.DLL (2.0 and 2.5) now has a function
Spline (X, x1,y1, x2,y2, ...)
which interpolates the given X with a bicubic spline and gives back the corresponding Y (useful mainly together with Zoom)
E.g. try:
version().converttorgb32()
zoom(factor="Spline(n, 0,0, 10,1, 30,0.5,31,0.5, 100,0.5)", \
dstx="Spline(n, 0,200, 30,200, 100,400)", \
show=true)
So you can give a simple "path" to the parameters instead of fiddling with sin, cos, exp,...
