Blt - Color Key - System Memory to Primary Memory
Note This content applies to the Windows Logo Kit (WLK). For the latest information using the new Windows Hardware Certification Kit (HCK), see Windows HCK User's Guide on the Windows Hardware Dev Center.
Type: Automated Test
Most of the Microsoft DirectDraw tests (including the Blt - Color Key - System Memory to Primary Memory test) are located in Fnddraw.exe. You can run Fnddraw.exe outside of the 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 visually analyze the blt results. Use the <Pause> key to pause and resume.
Use the <ESC> key to abort a test run. Be patient because some tests are more responsive than others.
You do not need Fnswtt.dll to run this test. It is used only for WTT logging.
This test ensures that display drivers that claim to support system-to-video color key blts perform them correctly. The tests perform simple source and destination color key blts from system memory to the primary surface. Blt results are compared against a simulation by using either GDI operations or the test's internal software blitter. Images are expected to match exactly.
This test consists of the following Fnddraw cases:
BLT, single DESTKEY, System to Primary
BLT, single SRCKEY, System to Primary
To run this test, use the Fnddraw.exe executable file.
- Run Time: 00:20:40
- Log File:
- System Restart Required: No
- Test Category:
- Supported operating systems for Logo or Signature testing:
Windows Server 2008 R2
Windows Server 2003
The test tool requires the following software:
- Supported operating system (see list above).
- Software components included with the device that is being tested.
- DirectX version 7.0 or later
- Hardware Requirements
- Device to be tested
- Computer that meets the minimum software requirements
- Windows keyboard
- Two-button pointing device
- Color display monitor capable of at least 1024 by 768 resolution, 32-bits per pixel, 60 Hz
- Hard drive with a minimum of 20 GB available on partition C:
- Display adapater with DDraw capabilities
There are no specific steps to follow for this test. You should run Fnddraw.exe.
fnddraw.exe dd_vvb.pro -r -c -p"m%MONITOR%"
Replace the %MONITOR% parameter with a 1-based index that corresponds to the display that you are testing.
Turn off the screen saver and disable the power management before you run this test. Mode changes and full-screen applications can cause failures, so you should avoid them.
Microsoft DirectX SDK (version 7.0 or later)
