Example #1

File: pattern.go Project: jimmyfrasche/cairo

//NewLinearGradient creates a new linear gradient, from start to end,
//with specified color stops.
//
//Originally cairo_pattern_create_linear and cairo_pattern_add_color_stop_rgba.

	x0, y0 := start.c()
	x1, y1 := end.c()
	p := C.cairo_pattern_create_linear(x0, y0, x1, y1)
	P := patternGradient{
		XtensionPattern: XtensionNewPattern(p),
	}
	P.addColorStops(colorStops)
	return LinearGradient{
		patternGradient: P,
		start:           start,
		end:             end,
