Functions ¶
func DrawMask ¶
func DrawMask(dst Image, r image.Rectangle, src image.Image, sp image.Point, mask image.Image, mp image.Point, op Op)
DrawMask aligns r.Min in dst with sp in src and mp in mask and then replaces the rectangle r in dst with the result of a Porter-Duff composition. A nil mask is treated as opaque.
func HorizontalLine ¶
HorizontalLine draws a line between (x,y) and (x+w,y).
func RoundedBox ¶
RoundedBox draws a filled rectangle with radius pixels rounded corners.
func RoundedRectangle ¶
RoundedRectangle draws a rectangle with radius pixels rounded corners.
