I am just now becoming acquainted with the roScreen component and its interfaces. I am trying to make a channel where there is a video playing on the left side of the screen and a menu on the right side were you can select different feeds. However, I have a problem where after using the roscreen clear function to set the background color, the video appears behind the background, where it can be heard, but not seen. What can I do to fix this?
You can definitely use Clear(). Just make sure you call SetAlphaEnable(True) on the screen, and that you're passing in a 0 alpha value on the color you're Clear()'ing with.
screen = CreateObject("roScreen", True) . . . ' Enable alpha on the screen screen.SetAlphaEnable(True) ' Clear the screen, so the video can be seen behind screen.Clear(&H00000000) ' &H00000000 = 0 = fully transparent black ' Draw your other screen elements . . . screen.SwapBuffers()
Also, make sure you've called SetDestinationRect() on your roVideoPlayer object to specify where the video should be displayed.
Also, if you want a solid background with the Video appearing "on top" of the background, I would suggest, in Photoshop, create a transparent layer, past your solid background to a layer on top, cut out a hole the size of the video, and save as a transparent .PNG.
