Blt - Color Key - VMem to Primary
This automated test performs color-keyed blts from offscreen video memory to the primary memory.
Blt results are compared against a simulation by using either Graphics Device Interface (GDI) operations or the test's internal software blitter. Images are expected to match exactly.
Drivers must support source color key blts between video memory surfaces. Destination color key blts and "space" blts are optional.
This test consists of the following Fnddraw cases:
BLT, DESTKEY Space, VMem to Primary
BLT, single DESTKEY, VMem to Primary
BLT, SRCKEY Space, VMem to Primary
BLT, single SRCKEY, VMem to Primary
This topic applies to the following test jobs:
Blt - Color Key - VMem to Primary
Blt - Color Key - VMem to Primary (WoW64)

Before running this test, turn off the screen saver and disable power management. Mode changes and full-screen applications can cause failures, so you should avoid them.
More information
Most of the Microsoft® DirectDraw tests (including the Blt - Color Key - Video Memory to Primary Memory test) are located in Fnddraw.exe. You can run Fnddraw.exe outside of the Display Compatibility Test (DCT) shell, and select initial tests. On the Tests menu, click Select Tests.
The test titles that are listed in the DCT shell do not directly match the test names in Fnddraw.exe. In fact, the names in the DCT often refer to a group of Fnddraw tests. You can obtain the Fnddraw test case names from the DCT log file.
You can pause many Fnddraw tests (especially blt-related tests) to give you time to analyze the blt results. Use the Pause key to pause and resume.
Use the Esc key to stop a test run. Be aware that some tests are more responsive than others.
