MILERR_PREFILTER_NOT_SUPPORTED

MILERR_PREFILTER_NOT_SUPPORTED is a Windows Media Integration Layer (MIL) HRESULT. It indicates that the current rendering path cannot apply the selected bitmap prefiltering mode.

Diagnostic discriminator: Render the same bitmap with prefiltering disabled while preserving the scale and effect. Success on that control isolates unsupported prefilter capability; unrelated format, timing, or driver changes should not precede this test.

What to check for MILERR_PREFILTER_NOT_SUPPORTED

Check the bitmap effect, scaling mode, and graphics-device capabilities used by the request.
Disable or replace the prefiltering option with a rendering mode supported by the target device.
Do not force the unsupported state after a device or display configuration change.
