      • Raw

        public static final int Raw

        No compression. The image data stored as raw bytes in RGBA planar order. That means that first all R data is written, then all G is written, then all B and finally all A data is written.

      • Rle

        public static final int Rle

        RLE compressed. The image data starts with the byte counts for all the scan lines (rows * channels), with each count stored as a two-byte value. The RLE compressed data follows, with each scan line compressed separately. The RLE compression is the same compression algorithm used by the Macintosh ROM routine PackBits and the TIFF standard.
