G120HDR + G120 BitmapConvertBPP

I am trying to get an SPI display working on my G120 HDR RevC. I was wondering if there is native support for Bitmap Conversion. I have tried to include the libraries for the GHI.OSHW.Hardware Util convertor but I am getting an error for Hardware not Supported.

Here is the call I am using for Paint

Util.BitmapConvertBPP(bitmapbytes, vram, Util.BPP_Type.BPP16_BGR_BE);

Does anyone have any insight into this?


Please see n18 display driver for an example
