Programming Reference:VisualizationDemo Signal Processing

Location

src/contrib/SignalProcessing/VisualizationDemo

Synopsis

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.

Inheritance

The VisualizationDemoFilter signal processing filter derives from GenericFilter.

Parameters

VisImageWidth

Native image width in pixels.

VisImageHeight

Native image height in pixels.

VisImageBackground

The images' background color, in hexadecimal notation.

VisImageDecimation

A positive integer that indicates how often images are refreshed. 1 means every refresh on every signal packet.

VisMaxWindows

The maximum number of visualization windows created, or 0 for none.

Localization

The FeedbackDemo application provides an example for a translation table, giving translations for application screen messages, and shows how to wrap string literals in a LocalizableString call in order to look them up in the translation table.
