// NewImageFromImage creates a new image with the given image (source).

// If source's width or height is less than 1 or more than device-dependent maximum size, NewImageFromImage panics.

// If you are not sure, specify FilterDefault.

// Error returned by NewImageFromImage is always nil as of 1.5.0-alpha.
