CompressionMethod

public final class CompressionMethod extends System.Enum

Defines the compression method used for image data.

Fields

FieldDescription
RawNo compression.
RLERLE 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.
ZipWithoutPredictionZIP without prediction.
ZipWithPredictionZIP with prediction.

Raw

public static final short 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 short 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.

ZipWithoutPrediction

public static final short ZipWithoutPrediction

ZIP without prediction.

ZipWithPrediction

public static final short ZipWithPrediction

ZIP with prediction.
