Detailed Description

class for vertical or horizontal convolution

PROPERTIES: -KernelSize : length of linear kernel (>=1) NOTE - you need to exit the property editor for the kernel to be resized -Kernel : Kernel vector (line matrix) -Horizontal : boolean, otherwise vertical kernel -CenterOffset : center pixel position in the kernel, starting at 0 -StrictNoData : controls NODATA use true : any NODATA pixel in the convolution will make the center pixel NODATA false : if center is NODATA, then output center is NODATA, other NODATA pixels are processed as if they were zero in the convolution
