Programming Reference:VisualizationDemo Signal Processing
The VisualizationDemo signal processing module demonstrates how to send visualizations with arbitrary pixel content to the operator module. Two rendering methods are provided: Native Qt QPainter-based rendering, and BCI2000's own GraphDisplay based rendering.
The VisualizationDemoFilter signal processing filter derives from GenericFilter.
The VisualizationDemoFilter computes pairwise determination coefficients ( values) between its input channels. Determination coefficients are visualized in form of pie charts, and pie charts are sent to the operator module as bitmap visualization data.
Native image width in pixels.
Native image height in pixels.
The images' background color, in hexadecimal notation.
A positive integer that indicates how often images are refreshed. 1 means every refresh on every signal packet.
The maximum number of visualization windows created, or 0 for any number of windows.
