LEADTOOLS supports Run Length Encoding (RLE) compression in a wide variety of file formats. RLE is an ideal compression algorithm for images that contain long runs of the same color. A perfect example is a document image where the white background creates very long runs in certain areas of the image.
Additionally, LEADTOOLS implements PackBits compression, a variation of RLE compression used in TIFF files. PackBits uses a control byte to indicate how the next byte or run of bytes is used. The high bit in the control byte indicates the following byte or bytes are encoded as a run or not encoded. The lower 7 bits indicate the count of bytes.
