#include <revolution/vi.h>void VISetTrapFilter(VIBool filter) |
Specifiy VI_ENABLE to apply a trap filter onscreen. If VI_DISABLE is specified, a trap filter is not applied onscreen. |
None.
This function applies a trap filter to the screen when VI_ENABLE is specified.
Once the trap filter has been enabled with VI_ENABLED, the trap filter will continue to function until disabled with VI_DISABLE.
The trap filter affects only composite output.
When the trap filter is applied to the screen, cross-color is mitigated but the entire screen becomes slightly blurred. If a trap filter is not applied to the screen, the edges of the picture are sharper and text is easier to read, but cross-color occurs.
Changes do not take effect until VIFlush is called. See the VIFlush function reference for more details about when the change takes effect.
03/01/2006 Initial version.
05/09/2006 Added entry on the length of time that the trap filter continues to function.
