enum PresentationMode (rw)

This property determines the way a stimulus is presented. It is one of the following:

ShowHide
The stimulus is initially invisible, and visible while being presented.
Intensify
During presentation, the contrast of the stimulus is increased.
Grayscale
During presentation, the stimulus is displayed in grayscale rather than color.
Invert
During presentation, the stimulus appears color-inverted.
Dim
During presentation, the contrast of the stimulus is reduced.

float DimFactor (rw)

Determines the contrast ratio between presentation and non-presentation in Dim modes. Values greater 1 will result in a brighter appearance during presentation; however, due to saturation effects, the result may not be as expected.
