WDDM Blt - Stretch

  • 아티클

This automated test verifies that user-mode video drivers correctly implement stretching bit-block transfer (bitblt) operations.

The test creates two surfaces and uses the user-mode Blt Device Driver Interface (DDI) to transfer data between them. The test instructs drivers to perform stretching blts between the two surfaces. The source surface can exist in system memory while the destination exists in video memory. User-mode drivers must not crash or cause the Blt DDI call to fail during the test.

This topic applies to the following test jobs:

  • WDDM Blt - Stretch

  • WDDM Blt - Stretch (WoW64)
