Grayscale8BitQFactor property (ILEADRasterIO)

Remarks

(Document/Medical only) (Persistent property, available at design time) Indicates the compression quality to be used if JPEG, CMP or CMW compression for 8-bit grayscale images. This property is used only when saving in the LEAD Proprietary T44 format using the Save method (when using the SaveT44 method, all 8-bit grayscale segments are treated as picture segments).

Possible values are between 2 and 255, where 2 is the highest quality and 255 is the most compression. If the Grayscale8BitCoder property is CMW lossless or JPEG lossless compression, the Grayscale8BitQFactor property should be 0. This property is used only if FILE_LEAD_MRC or FILE_TIF_LEAD_MRC is set in the lFormat parameter of either the Save or SaveT44 methods. The default value is 2.
