How to use setRaster() and getCell()

Asked by Armel

Hy,

j've try this script :

R = SCREEN.setRaster(3,3)
R.highlight(5)

The result is OK. I visualize a part (0,0) on the screen

Now :

R1 = R.getCell(1,1)
R1.highlight(5)

Problem : I visualize the same area !?!?

Normaly, I must see central zone (1,1)

Where is the problem ?

wrong usage:

R = SCREEN.setRaster(3,3)

R now is the upper left third of the screen (the raster "knowledge" is stored in SCREEN)

R.getCell(1,1) hence ist the upper left third of the screen as well, since R does not have a raster and hence is itself.

usage:
setRaster(3,3) # now SCREEN has the raster
getCell(1,1) # is the middle third of the screen

SCREEN is never needed with undotted Region methods, since this is the default region in the standard usage meaning the Screen(0)
