◆ effectiveSmoothnessDistance()

qreal KisToolFreehandHelper::Private::effectiveSmoothnessDistance ( qreal speed ) const

stabilizer has inverted meaning of the "scalable distance", because it measures "samples", but not "distance"

Definition at line 465 of file kis_tool_freehand_helper.cpp.

{
    qreal zoomingCoeff = 1.0;
 
 
    if ((smoothingOptions->smoothingType() == KisSmoothingOptions::STABILIZER) ^
         smoothingOptions->useScalableDistance()) {
 
        zoomingCoeff = 1.0 / resources->effectiveZoom();
    }
 
    return zoomingCoeff * ((1.0 - speed) * smoothingOptions->smoothnessDistanceMax() + speed * smoothingOptions->smoothnessDistanceMin());
}
