CompressionMethod enumeration

Defines the compression method used for image data.

The CompressionMethod type exposes the following members:

Field	Description
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	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.
ZIP_WITHOUT_PREDICTION	ZIP without prediction.
ZIP_WITH_PREDICTION	ZIP with prediction.
