The grayscale values of the image are used as a height map, and an image is generated by using this height map with a light source to cast a shadow. The result is a grayscale image.
The following properties are supported:
The Enabled property can be set to true or false to switch the filter on or off.
The Bias property controls an intensity level that is added to the brightness of the embossed filter output. The value can range from -1.0 to 1.0 with brighter images as the value becomes more positive.
The example shows the application of an Emboss filter to an image. However when running tests, the Bias value did not seem to have any visible effect on MSIE 5.5 running on Windows 98.
