D3DKM_TRANSPARENTBLTFLAGS structure

Description

The D3DKM_TRANSPARENTBLTFLAGS structure specifies the display adapter's ability to perform a hardware-accelerated bit-block transfer (bitblt) with transparency.

Members

HonorAlpha [in]

A UINT value that specifies in a hardware-accelerated transparent bit-block transfer whether the alpha channel should be used during comparison. HonorAlpha can be one of the following values.

Value Meaning
1 The display adapter does not ignore the alpha channel when it compares the reference color with the source color.
0 The display adapter ignores the alpha channel when it compares the reference color with the source color.

Setting this member is equivalent to setting the first bit of the 32-bit Value member (0x00000001).

Value [in]

A member in the union that D3DKM_TRANSPARENTBLTFLAGS contains. This member can hold a 32-bit value that specifies the display adapter's ability to perform hardware-accelerated bit-block transfer with transparency.
