Note
Because Roto-Paint is vector based, you can also edit strokes by
changing the vector that draws them.
9. Now select a stroke on-screen by marqueeing some points together and move
them around. The box that displays around the selected points allows for scaling
and rotation ( FIGURE 6.11 ).
Figure 6.11. The box around selected vector points allows for greater ma-
nipulation.
Erasing and deleting strokes
Say I drew a lovely picture, but made a mistake. What if I want to erase or delete
something?
1. Double-click the Paint tool to access the Eraser tool, and then draw on-screen
where you drew before.
Note
If you happened to click the actual name of the stroke, then pressing
theBackspace/Deletekeywilljustdeletethename.Youneedtoclick
the icon to the left of the name.
