Forudindstillinger

Forudindstillinger er en fælles funktion for flere farvekommandoer. Du kan finde en beskrivelse i Afsnit 8.1.1, “Fælles funktioner for Farver”.

Radius

Standard deviation of gaussian neighborhood average for computing local contrast. If 0 is used a global threshold is used instead of one based on local contrast.

Antialiasing

This sets a rough target of levels of accuracy for antialiasing, or set to 1 to disable antialiasing.

Threshold level

Thresholding level consists of two values. Change the lower threshold towards 0 to minimize shadows or towards 1.0 to minimize highlights. The high threshold decides the maximum values to include, above this it gets set to 0.
