to 5; where 5 is the deepest emboss)

(from 0 to 255; where 255 is the brightest)

Explanation
The Emboss method creates an emboss effect on a raster image. To execute the Emboss method, set the image handle of the image in the SourceImage property. The Emboss method supports 8-bit grayscale, 16, 24, and 32 bit images.
Before executing the Emboss method, you must set the area on the image that will be affected. There are 4 ways to do this.
- To use a mask image, set the SelectMode property to EffectMask. Set the mask image handle in the SourceMask property
- To process the total image, set the SelectMode property to EffectAll
- To process the polygonal area on the image, set the SelectMode property to EffectPolygon. Set the appropriate values in the Point property
- To process an elliptical area on the image, set the SelectMode property to EffectEllipse. Select the ellipse by setting the appropriate values for the bounding rectangle in the Rect property
Note: When the SelectMode property is set to EffectPolygon or EffectEllipse, the values must be set in the Inside property.
If successful the resulting raster image data is set in the DestinationImage property.
