      static java.awt.image.BufferedImage convertToSinglePixelPackedSampleModel​(java.awt.image.BufferedImage image)

      • convertToSinglePixelPackedSampleModel

        public static java.awt.image.BufferedImage convertToSinglePixelPackedSampleModel​(java.awt.image.BufferedImage image)
        It seems that SinglePixelPackedSampleModel is the only fast mode when a color profile is converted. This is probably a bug (that has nothing to do with bugs 4886071 and 4705399). Note that grayscale images (TYPE_GRAY) are not converted.
