Members
ValueMemberDescription
0LayerResolutionComponentPositionQuality axis order. Image starts out blurry and becomes clearer and more detailed as additional data is decoded.
1ResolutionLayerComponentPositionResolution-axis order. Image starts out small and becomes larger as additional data is decoded. Higher compression ratios achieved by leaving lower resolutions in the file.
2ResolutionPositionComponentLayerResolution-axis order. Image starts out small and becomes larger as additional data is decoded. Higher compression ratios achieved by leaving lower resolutions in the file.
3PositionComponentResolutionLayerPosition axis order. Image starts out as a series of blocks starting from the top left corner. Additional portions of the image become visible as more data is decoded. Image data stored by spatial location.
4ComponentPositionResolutionLayerColor-axis order. Image starts out gray. Color is added as more data is decoded. Image data stored by color channel, starting with channel Y, then U, then V. If the transform to YUV option is used, the lowest decompressed image level for RGB is grayscale. Otherwise, the output is only the red channel.
