Pré-réglages

  « Presets » are a common feature for several Colors commands. You can find its description in Section 8.1.1, « Fonctions communes aux couleurs ».

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.

Blending Options, Aperçu, Merge filter, Diviser la vue

  These are common features described in Section 8.1.1, « Fonctions communes aux couleurs ».
