[Scilab-users] Fwd: plotting dots vs xfarc

Dear community,
I need to create images, which includes exact dot-coordinates, drawn as
filled circles.
All pixel coordinates of such an area would have to have exactly one single
pixel value.
The resulting graphic right now is stored via: xs2bmp.
to create the dots I naturally would use: plot (x,y,'o')
Issues here:
- It seems that the resulting pixels of the dot in the final image are not
equally colored.
- Especially pixels at the right lower "corner" seem to be off-colored.
So I tried: xfarc:
Issue here:
- xfarc() seems not always to find the correct x-y-location.
See example attached.
- The dots by plot() are colored white.
- The xfarc is colored blue.
I left some dots without xfarc() to demonstrate the issue of plot().
I think I could "brute-force" pixel values of the underlying image (not
black for real purpose) to correct pixel values.
But actually I wanted to avoid that.
Any hint?
Used: Scilab 6.1.0
Best regards,
Philipp
