hi,<div><br></div><div>this is regarding alpha channel.</div><div><br></div><div>i am able to change the alpha value for an image by setting new alpha value for every pixel.</div><div><br></div><div>but i was thinking we also could set the alpha value for all of the pixels in a window/screen just but setting the value somewhere, say using ctl. is this not possible in plan9 or inferno? i am wondering how i got that thinking.</div>
<div><br></div><div>thanks</div><div>dharani</div>
