Hi Philippe,
mind that ImagePlus.flatten returns a flattened ImagePlus, it does not
modify the original.
Or could it be that you want the opposite of 'flatten'?
'flatten' writes the lines and other objects currently present as
overlay into the image, modifying the image data.
'drawLine' (ImageProcessor, not ImageCanvas method) irreversibly draws a
line by modifying the pixels. The same is true for the macro drawLine
command (not for macro Overlay.drawLine).
You cannot convert that into an overlay any more, and you cannot recover
the pixel data that were overwritten.
Michael
