{
uint32_t w = 0,h = 0;
// skc_interop_size_get(compute->interop,&w,&h); TODO skc.h
SkDevice_Compute * const device_compute = new SkDevice_Compute(compute,w,h);;
SkCanvas * const canvas = new SkCanvas(device_compute,SkCanvas::kConservativeRasterClip_InitFlag);
//
// destroy device upon surface destruction
//
device = sk_sp<SkBaseDevice>(device_compute);
//
// move origin from upper left to lower left
//
SkMatrix matrix;
