PsdCompressionMethod enumeration

PsdCompressionMethod enumeration

Defines the compression method used for image data.

The PsdCompressionMethod type exposes the following members:

Fields

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.
