304 output = framebuffer pixel * alpha + video pixel * (1 - alpha).
305 The actual alpha depth depends on the framebuffer pixel format.
308 - Use a global alpha value to blend the framebuffer with video
309 images. The blend function is: output = (framebuffer pixel * alpha
310 + video pixel * (255 - alpha)) / 255. The alpha value is

23 memory. When the device captures an alpha channel the alpha component will have
24 a meaningful value. Otherwise, when the device doesn't capture an alpha channel
25 but can set the alpha bit to a user-configurable value, the

27 specify that alpha value, and the alpha component of all pixels will be set to
