17. How To Tutorial # 5: How to change the output image resolution

The X and Y resolution of the rendered output image is set with the Nt_RESOLUTION option of the command. See the Nt_RESOLUTION option in for further information.

The following snippet of C code shows how to set the output resolution to 320x200:

resolution_example()
{
	Nd_Int	Nv_XY_Res_Params[2];

	/* Set the output resolution to 320x200 pixels */
	Nv_XY_Res_Params[Na_X_VALUE] = 320;
	Nv_XY_Res_Params[Na_Y_VALUE] = 200;

	Ni_Option(Nt_RESOLUTION, (Nd_Int *) Nv_XY_Res_Params, Nt_CMDEND);
}
