MaskTableL property (Main Control)

Visual Basic example
Visual C++ 4.0 example

Syntax short MaskTable (long lIndex);

Overview:  Refer to Changing Brightness and Contrast.

Remarks

(Document/Medical only) Lookup table that identifies the valid values in the HTableL property. This is one of the four tables that the RemapHue method uses to change the bitmap's hue, saturation and value. Hue, Saturation, and Value levels range from 0 to 255. The current hue, saturation and value of a pixel correspond to the table indexes. If the bUseMaskTable parameter is set to TRUE when the RemapHue method is called and the RemapHueTablesSize property is set to 65536, then this table is used to identify which values in the HTableL property are valid. If MaskTableL(i) is non-zero, then HTableL(i) is to be used. If MaskTableL(i) is 0 then HTableL(i) is ignored.

This property provides support for 16-bit grayscale and 48-bit color images. Support for 16-bit grayscale and 48-bit color images is provided only in Document/Medical toolkits.
