TDA4VM: TDA1VM: How to draw text or lines to a scaling graph

Part Number: TDA4VM

Hello sir:

Mr. Brijesh Jadav  hello me solved zoom in/out problem in the post https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1015756/tda4vm-how-to-zoom-in-or-zoom-out-a-running-picture/3755939?tisearch=e2e-sitesearch&keymatch=%252525252520user%25252525253A491470#3755939

Additionally, I want to add some texts or lines on the zoom in graph. It was failed in appGrpxInit beause the Graphics pipeline cannot support scaling as Mr. Brijesh Jadav told me. If I change the Graphics pipeline to video pipeline(change pipeid from 1 to 2), the graph background is not transparent, and I cannot change the background  no matter what I do.  Is there any other way to draw text or lines on a scaling graph?
