In fact I wrote a hack within GrText() that will reset the 'usebackground' flag of graphics context to 0. This will serve my purpose, but I want to use GrGCUseBackground() to disable the flag. Problem is I can't see any such API in the code-base.
Thanks for giving me pointer.

I am using 'microwindows-0.91'. Do I need to apply any patch?

The screen should be as follows: Whether the screen is a TV or not is completely seperate from the business of nano-X writing its framebuffer. Setting up any alpha or video along with the nano-X framebuffer will have to be done outside of nano-X. : 1. There is a background image, that is, a gif file displayed as screen : background (implemented using GrSetBackgroundPixmap()). This should work fine as is. : 2. A text is displayed on the top of the background on TV screen. : Now I want that the text background to be transparent. That means the : background image should be displayed from within the text message. Is it : possible using nano-x? : When you set drawing text background to OFF with GrGCUseBackground, then text will be drawn without any background clears, and should be fine. : Assume there is no video on TV. : Again, that doesn't really have anything to do with how nano-X writes the framebuffer supplied to it.
