Parameter

Denoise	Make settings for the noise suppression.
Straighten	Straighten the view of the yarn.
Smoothen	Smooth out the thread delimitation of the view.
Indent	Narrow the thread delimitation of the view.
Supress Moiré Pattern	In the fabric view it is possible to get moiré patterns with a low zoom. Supress Moiré Pattern reduces this effect in the view of the pattern.

Make the settings of the parameters in order from top to bottom if possible and then readjust as necessary.

General settings at the right buttom:

Background	Set the background color.
Zoom	Define the zoom of the view.
