A pre-multiplied gradient of yellow to transparent to blue compiste of a whitye background is identical to a gradient of yellow to white to blue (fully opaque). What do you want to achieve with a gradient that has alpha transparency and have you tested any of this by observing the difference between pre-multiplied colorspace and non pre-multiplied colorspace? -- Alan Gresley http://css-3d.org/ http://css-class.com/
