Overview of LEADTOOLS RLE and PackBits Image Compression SDK Technology
RLE is an acronym for Run Length Encoding. Images frequently contain the same character repeated many times in a row. For example, text files use multiple spaces to separate sentences, indent paragraphs, format tables & charts, etc. Images can also have runs of the same pixel color. A perfect example of this would be a document image: the white background would create very long runs in certain areas of the image.
A flavor of RLE compression used in TIFF files is PackBits. PackBits uses a control byte to indicate how the next byte or run of bytes to be used. The high bit in the control byte indicates if the following byte or bytes should be a run or as they are. The lower 7 bits indicate the count of bytes - 1.
