);

Parameter

Hinweise

Applications that wish to clear a render target to a specific integer value bit pattern should render a screen-aligned quad instead of using this method. The reason for this is because this method accepts as input a floating point value, which may not have the same bit pattern as the original integer.

Differences between Direct3D 9 and Direct3D 11/10:

Unlike Direct3D 9, the full extent of the resource view is always cleared. Viewport and scissor settings are not applied.
