It is possible to turn any valid image that already exists into a silhouette via the
create_silhouette method, which looks like this:
create_silhouette("<name of image>", r=0, g=0, b=0, a=1)
1 2 3 4 5
# Create a black silhouette (default) image john_silhouette = create_silhouette("john a_0") # Create a white silhouette image john_silhouette = create_silhouette("john a_0", 1, 1, 1)
In addition to specifying the image to turn into a silhouette you can also optionally add four number values which are one part of an RGBA color (Red, Green, Blue, Alpha/Opacity) each. The method will use this color to fill the silhouette. The values range from 0 (black) to 1 (white).
