From BCI2000 Wiki

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.
HideShow
The stimulus is initially visible, and invisible while being presented.

float DimFactor (rw)

Determines the contrast ratio between presentation and non-presentation in Dim and Intensify modes. In Intensify mode, values greater 1 will result in a brighter appearance during presentation; in Dim mode, values greater 1 will result in a darker appearance during presentation. Due to saturation effects, the result may not be as expected.
