 ::Enables ''auto scaling''. Auto scaling divides the output of the convolution by the sum of the elements of the matrix. The value of {{FuncArg|divisor}} is applied in addition to this auto scaling factor. If the sum of elements is zero, auto scaling is disabled.
-The {{FuncArg|divisor}} is usually the sum of the elements of the matrix. But when the sum is zero, you can leave {{FuncArg|divisor}}=1 and use the {{FuncArg|bias}} setting to correct the pixel values. The {{FuncArg|bias}} could be useful if the pixel values are negative due to the convolution. After adding {{FuncArg|bias}}, the pixels are clipped to the range 0-255.

 Around the borders the edge pixels are simply repeated to service the matrix.
