GetTemporalFilterModeAndParameters (16)
Description
This function gets the temporal filter parameters.
Call with
AL = 16 (function number).
BL = Parameter reporting mode.
00 = Original parameters.
01 = Absolute parameters.
Returns
BL = Temporal filter mode.
00 = Temporal filter disabled.
01 = Temporal filter enabled.
If BL is 00 (original parameters), the additional returns are:
CX = Spatial filter box size expressed as a percentage (%) of
the full screen size.
DX = User-specified temporal filter time (ms). This parameter
returns the exact number of milliseconds set by the call
to SetTemporalFilterParameters (15).
If BL is 01 (absolute parameters), the additional returns are:
CH = Spatial filter box size x (actual size of the box in pixels).
CL = Spatial filter box size y (actual size of the box in pixels).
DX = Actual temporal filter time used (ms). This parameter
returns the number of milliseconds that the driver
actually uses for the wait (modulo 55 ms). Note that the
actual time waited may still vary by +/- 55ms.
