Hi,
sorry to interrupt, the following lines should work in IPCV to count the
white and black pixels:
1. after imread, the image return as boolean as the image is an binary
image.
2. assume that you have previous code and imread the image and the
scilab variable for the image is "img"
-->
... the code should work under win7 if you have the *scicv*-module
installed via atoms.
Note that you have to "activate" scicv to use its functionshence the:
scicv_Init();
at the beginning of the code.
I wrote the code at win10, but I doubt that this has an influence.
Good luck,
Philipp

Hello Philipp,
Thank you for your program, it looks like it would do exactly what I
wanted. However (as I should have stressed before) I work under win7. In
this environment, the only image processing toolbox is IPCV in which
several functions are lacking, namely
scicv_Init(); matplot();
do you mean something like this?
See example attached
It needs: Scilab Computer Vision Module
But as mentioned before:
The number of pixels you will find depend on how big you define image size
/ line width, etc.
Best regards,
Philipp

Ok. So it is completely size/scale dependent and has to be done on the
bitmap image. Besid

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

What is the data structure of your picture?
A matrix of dots?
A Scilab figure containing polylines?
