Remarks

This method applies an effect to an image that makes it look like it has been drawn with colored pencils.
As an example, if you use the following figure:

If you call the ColoredPencilExtendedCommand using the following values:

Parameter	Value
Size	5
Strength	4
Threshold	0
PencilRoughness	250
StrokeLength	15
PaperRoughness	100
Angle	0
Flags	ColoredPencilExtendedCommandFlags.Artistic

The following figure results:

This method supports 12-bit and 16-bit grayscale and 48 and 64-bit color images. Support for 12-bit and 16-bit grayscale and 48-bit and 64-bit Effects images is available only in the Document/Medical toolkits.
This method does not support signed data images.
This command does not support 32-bit grayscale images.
