But I can't see any API called GrGCUseBackground() as you mentioned. I am
using 'microwindows-0.91'. Do I need to apply any patch?

Aveek

: Well, consider I am writing an application for TV and the application 
should
: display a simple screen on TV. 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.

Regards,

Greg
