Member Data Documentation

bool pagespeed::image_compression::FrameSpec::hint_progressive

Whether this frame was progressively encoded by the origin site, so that it could begin to be rendered even before the entire image was transferred. This does not affect the data format passed in or out of this API, but provides a hint that API clients may choose to take.
