The Interpolate flag advises the renderer to smooth pixel boundaries when scaling the image above its natural resolution. When true, the renderer may apply a smoothing filter; when false, the raw pixel values are used without interpolation.

This flag is advisory. High-resolution output devices may ignore it. It primarily affects screen rendering where images are scaled up significantly.
