Declaration: LaplaceFilterXY (var Data: TDouble2DArray; PixMask: TBool2DArray): integer;
Applies a Laplace kernel filter to the data in the two-dimensional array Data and writes the results back to Data. The parameter PixMask contains an optional pixel mask which controls which cells of the array Data should be processed. A TRUE value excludes the corresponding cell from calculations.

The function returns the following error codes:

 0 .... everything is OK
-1 ... the dimensions of Data and PixMask do not match
