Functions ¶
func ColorSurface ¶
ColorSurface is a type that implements all of color.Color's methods and wraps around a cairo.Surface. This is useful for SetColor.
Note that calling RGBA on the returned color will always return a transparent color.
Types ¶
type Canvas ¶
type Canvas struct {
// contains filtered or unexported fields
}
Canvas implements the vg.Canvas interface, drawing to a cairo.Context.
func (Canvas) FillString ¶
FillString implements vg.Canvas.
func (Canvas) SetLineDash ¶
SetLineDash implements vg.Canvas.
func (Canvas) SetLineWidth ¶
SetLineWidth implements vg.Canvas.
