yPos: Type: System Int32
the y coordinate of the top left hand corner of the search area

width: Type: System Int32
the width of the search area

height: Type: System Int32
the height of the search area

searchRadius: Type: System Int32
increase the search area by searchRadius pixels in each direction

timeout: Type: System Int32
The total time in milliseconds to wait before timing out.

maxDiscrepancy: Type: System UInt32
the maximum number of pixels in the image that are allowed to not match

Return Value

The rectangle where the image was found. This value is also copied to LastFoundLocation

Exceptions
