Hi, Subbu,

First, decide on a color to represent "transparent," and then in the  
paint tool, paint with that color everywhere that you intend to be  

After saving the painting and exiting from the paint tool, bring up  
the halo on the resulting SketchMorph, and from its halo menu choose  
the last item, 'painting...' and from the submenu choose "erase  
pixels of color...".  In the resulting "eyedropper" cursor mode,  
click on the color you chose to represent transparency, and you're done.
