Hi
I use Terasik DE2-115 FPGA Cyclon IV board (Quartus 11.1) I'm trying to use the VIP Core Alpha Blending Mixer based on tPad_VIP example from Terasic. Layer 0 is a plain black background. Layer1 are clocked video input and layer2 are text overlay. Text layer1 superimposed on a layer2 of the video stream without Alpha Blending. All is well, but the text layer background is not transparent and closes the video stream. Can I set the transparent color text layer? I need to display text and graphic information over the video stream on a transparent layer. Or it is necessary to use Alpha Blending? Thank you.Link Copied
