TDA3XEVM: Bitmap Transparency on GRPX Overlay

Part Number: TDA3XEVM

Hi all

I could see that i can change the globalAlpha to change the opacity of entire overlay.

Is it possible to draw individual bitmaps with custom opacity value, drawn with Draw2D_drawBmp.

I need to keep the opacity levels of other text/bitmaps drawn.

Is there any usecase in vision sdk implemented a similar drawing method?

Hi Naveen,

It is possible, but you need to use one of the ARGB formats and control alpha value for each pixel.

Hi Brijesh, thanks for the quick reply.

I hope this should be the BGRA16_4444 format. (SYSTEM_DF_BGRA16_4444)
I could only see use of SYSTEM_DF_BGR16_565 format for bitmaps. Is there any example i can refer in Visionsdk

Naveen,

GRPX pipeline supports many ARGB formats. I think Even bitmap utility in VSDK support ARGB444.
