Hello,
I am mainly interested in obtaining the ratio (number of white
pixels)/(number of black pixels), so that units are not of primary
interest.
Ok. So it is completely size/scale dependent and has to be done on the
bitmap image. Besides exporting the figure then reloading with imread
(present e.g. in IPCV Atoms module) I don't see other solutions.

My thanks to all respondants.
The figure is in internal Scilab firmat made up of polylines., the
border is a polygon.
you did not say if you want to compute a surface in current units or
really compute a surface in pixels

Using Scilab (6.02/Win7), I have drawn a picure made up of thick
lines and
arcs, within a region with irregular borders.
What is the data structure of your picture?
A matrix of dots?
A Scilab figure containing polylines?
