Class Method Details

.surface(width, height) ⇒ Object

Create a drawing surface of the given pixel size. With a block, yields the surface, finishes drawing when the block returns, and returns the surface (so you can chain #save / #to_png). Without a block, returns an open surface.

width/height are whole pixels; a Float is truncated toward zero (NUM2INT).
