Hello,
So I'm working on a simple kiosk style app. There is a background
and in the foreground are images and text. Pretty simple. The text needs
to scroll, which it does. Everything is working, however I'm wondering
about layers. I don't fully understand them, but I'm wondering if the
following explanation is correct.
If I were to setup the application and it had two layers, could I get an
interface to the lower & higher layers and draw to them independently
and DirectFB would deal with flipping if/when either changed (not saying
I don't call flip), but for example, if the background never changes,
and I draw clear the top layer and redraw it, then call flip, it'll show
properly without me having to redraw the bottom layer as well? Is that
how they work?
