Function Documentation

void dmxComputeWidthHeight

(

DMXRecomputeFlag

flag

)

Computes the global bounding box for DMX. This may be larger than the one computed by Xinerama because of the DMX configuration file.

void dmxConnectionBlockCallback

(

void

)

A callback routine that hooks into Xinerama and provides a convenient place to print summary log information during server startup. This routine does not modify any values.

void dmxSetWidthHeight	(	int	width,
		int	height
	)

We may want the wall dimensions to be different from the bounding box dimensions that Xinerama computes, so save those and update them here.
