Hi, I'm trying to apply an Alpha gradient to a bitmap that I've created from a PNG. I want the image to be opaque at the top and fade to transparent at the bottom. I know this can be done be using getPixels and setPixels for Bitmap and iterating through each row of pixels in the Bitmap and setting the alpha values accordingly, but i was hoping there was a slightly neater way of doing this. I have been looking at the LinearGradient Class and using a Porter Duff transfer mode, but i don't seem to be having much luck with this. It seems that my source image is lost when i apply the Shader to the drawable.
Anyone have any tips on how i might apply an alpha gradient to a bitmap? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
