Manager.CheckDeviceFormatConversion Method |
Language: |
Tests a device to determine whether it supports conversion from one display format to another.
public static bool CheckDeviceFormatConversion(int, DeviceType, Format, Format); public static bool CheckDeviceFormatConversion(int, DeviceType, Format, Format, out int);
Using Manager.CheckDeviceType to test for compatibility between a back buffer and the display format returns appropriate values. This means that the call reflects device capabilities. If the device cannot render to the requested back buffer format, the call still returns ResultCode.NotAvailable. If the device can render to the format but cannot perform the color-converting presentation, the return value is also ResultCode.NotAvailable. Applications can discover hardware support for the presentation itself by calling Manager.CheckDeviceFormatConversion. No software emulation for the color-converting presentation itself is offered.
Manager.CheckDeviceFormatConversion also can be used to determine which combinations of source surface formats and destination surface formats are permissible in calls to Device.StretchRectangle.
Color conversion is restricted to the following source and target formats.
- Source format must be a four-character code (FOURCC) format or a valid back buffer format. For a list of these, see FOURCC Formats and BackBuffer or Display Formats.
- Target format must be one of the following unsigned formats. For more information, see Unsigned Formats.
