• The strokes should be near the boundary of the object, but not right up against the
edge.
• Strokes that are closer to the boundary will dominate the creation of the mask.
• If the foreground or background has varying colors, the strokes should cover
these colors.
• After processing the mask, if you see gray areas in the foreground object that
should be completely white, make additional foreground marks in those areas.
• If you see gray mask areas in the background that should be completely black,
make additional background marks.
• If any fine foreground details are missing from the mask, click on the Unknown
brush and draw over them with the left mouse button. This instructs EZ Mask to
pay special attention to these areas and will help recover lost detail.
• The general rule is don’t put different stroke types too close together unless you
need to.
Warning: If you only provide a few sparse strokes, a Stroke trimap will take longer to
process than a filled trimap.
