This option scales the input image to a certain size before running the algorithm on it. Uncheck the box to use the average color of the input image as the background. This is most useful for bezier curves to get good image coverage more quickly.
Uncheck the box to let the program optimize the stroke width for each curve. Stroke width: Set the stroke width to be used for quadratic bezier curves.Shape alpha: Constrain the program to use a particular alpha value for each shape, or uncheck the box to let the program optimize the alpha value for each shape individually.Combo mode allows the program to pick the best shape at each iteration. Most of these are filled shapes, but the beziers are stroked. Shape type: Choose the type of shape that the program should use to draw your image.Image: Choose the input image that you want the program to draw using primitive shapes.
