header (8 bytes): An RDPGFX_HEADER (section 2.2.1.5) structure. The cmdId field MUST be set to RDPGFX_CMDID_SURFACETOSURFACE (0x0005), while the flags field MUST be set to zero.
surfaceIdSrc (2 bytes): A 16-bit unsigned integer that specifies the ID of the surface containing the source bitmap.
surfaceIdDest (2 bytes): A 16-bit unsigned integer that specifies the ID of the destination surface.
rectSrc (8 bytes): An RDPGFX_RECT16 (section 2.2.1.2) structure that specifies the rectangle that bounds the source bitmap.
destPtsCount (2 bytes): A 16-bit unsigned integer that specifies the number of RDPGFX_POINT16 (section 2.2.1.1) structures in the destPts field.
destPts (variable): A variable-length array of RDPGFX_POINT16 structures that specifies target points on the destination surface to which to copy the source bitmap. The number of structures in this array is specified by the destPtsCount field.
