Notes to
(1) The maximum and minimum guard bands values specify a range in which the input should always fall. The 2D FIR filter behaves unexpectedly
(2) The output is constrained to fall in the specified range of maximum and minimum guard band values.
(3) You can specify a higher precision output by increasing Bits per pixel per color plane and Move binary point right.

Value
Choose the maximum image width in pixels.
The number of color planes that are sent in sequence
over one data connection. For example, a value of 3 for
R'G'B' R'G'B' R'G'B'.
Choose the number of bits per pixel (per color plane).
Choose whether input is unsigned or signed 2's
complement.
Turn on to enable a defined input range.
Set input range maximum value.
Set input range minimum value.
Choose the number of bits per pixel (per color plane).
Choose whether output is unsigned or signed 2's
complement.
Turn on to enable a defined output range.
Set output range maximum value.
Set output range minimum value.
Specify the number of places to move the binary point.
This can be useful if you require a wider range output on
an existing coefficient set.
Choose the method for discarding fractional bits
resulting from the FIR calculation.
Choose the method for signed to unsigned conversion of
the FIR results.
