Blt - Exotic

This automated test analyzes the GetBltStatus, Zbuffer Blt, Blt FOURCC, and Copy FOURCC functions.

This topic applies to the following test jobs:

• Blt - Exotic

• Blt - Exotic (WoW64)

Test details

Running the test

Before you run the test, complete the test setup as described in the test requirements: Graphic Adapter or Chipset Testing Prerequisites.

In addition, this test requires the following software and hardware:

• DirectX® version 7.0 or later

• Display adapter with DDraw capabilities

Troubleshooting

For troubleshooting information, see Troubleshooting Device.Graphics Testing.

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

This test consists of the following test cases that evaluate a variety of miscellaneous Blt operations:

• "3D_Depth Fill Blt Test" performs Z-Fills operations on z-buffers (including both 16- and 32-bits per pixel (bpp) types).

• "BLT_OffscreenOverlap" performs blts on a variety of offscreen surfaces where the source and destination surface are the same. Blt rectangles are chosen so that they overlap. The blts are simulated by the tests' internal software blitter and compared. Because the blts are simple copies, the real blt and simulation should match exactly.

• "BLT_GetBltStatusPostFlip" tests the reliability of the GetBltStatus function before, during, and after a Flip operation.

• "BLT_GetBltStatusMultBlts" tests the reliability of the GetBltStatus function before, during, and after a Blt operation.

• BLT_ZBuffer performs blts between Z-buffer surfaces and compares them.

• "BLT, FourCC to FourCC" performs simple copy blts between a variety of offscreen surface formats, including FourCC formats. FourCC formats are tested only if the driver sets the DDCAPS2_COPYFOURCC flag (which drivers are required to set).

• "BLT, FourCC to RGB conversion" performs blts from YUV (FOURCC) surfaces to an RGB primary surface. This test is run only if the driver sets the DDCAPS_BLTFOURCC flag.

• "BLT, FourCC to RGB stretch" performs stretched blts from YUV (FOURCC) surfaces to an RGB primary surface. This test is run only if the driver sets the DDCAPS_BLTFOURCC and DDCAPS_BLTSTRETCH flags.

Most of the Microsoft DirectDraw tests (including the Automatic Stereo test) are located in Fnddraw.exe. You can run Fnddraw.exe outside of the Display Compatibility Test (DCT) shell, and select individual 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.
