get-size in dc<%>

Gets the size of the destination drawing area. For a dc<%> object obtained from a canvas<%>, this is the (virtual client) size of the destination window; for a bitmap-dc% object, this is the size of the selected bitmap (or 0 if no bitmap is selected); for a post-script-dc% or printer-dc% device context, this gets the horizontal and vertical size of the drawing area.

• (send a-dc get-size) -> two non-negative real numbers: width and height
