KernelConvolve

Declaration: KernelConvolve (Kernel, InData: TDouble2DArray; var OutData: TDouble2DArray; Feedback: boolean): integer;
KernelConvolve calculates for each cell of the array InData the convolution of the matrix cells with the kernel given by the parameter Kernel. The kernel has to be quadratic with an odd number of pixels along the egde. The results are written to the array OutData which is automatically resized to match the size of InData. If Feedback is set to TRUE, the progress bar at the bottom of the ImageLab main window indicates the progress of the calculation, if set to FALSE no visual feedback is provided.

The function returns the following error codes:

 0 ... everything is OK, OutData has been filled by the convolution results
-1 ... the Kernel is not quadratic
-1 ... the size of the Kernel is even
-3 ... the size of the Kernel is less than 3
