Members

lAlphaBitDepth

Alpha channel bit depth (1, 2, 4, or 8) for an alpha-only surface (DDPF_ALPHA). For pixel formats that contain alpha information interleaved with color data (DDPF_ALPHAPIXELS), you must count the bits in the lRGBAlphaBitMask member to obtain the bit depth of the alpha component.

lBBitMask

Mask for blue bits.

lBumpBitCount

Total bump-map bits per pixel in a bump-map surface.

lBumpDuBitMask

Mask for bump-map U-delta bits

lBumpDvBitMask

Mask for bump-map V-delta bits.

lBumpLuminanceBitMask

Mask for luminance in a bump-map pixel.

lFlags

Constants of the CONST_DDPIXELFORMATFLAGS enumeration describing optional control flags.

lFourCC

FourCC code. For more information see, Four-Character Codes (FOURCC).

lGBitMask

Mask for green bits.

lRGBAlphaBitMask and lYUVAlphaBitMask and lLuminanceAlphaBitMask

Masks for the alpha channel.

lLuminanceBitCount

Total luminance bits per pixel. This member applies only to luminance-only and luminance-alpha surfaces.

lLuminanceBitMask

Mask for luminance bits.

lRBitMask

Mask for red bits.

lRGBAlphaBitMask and lYUVAlphaBitMask

Masks for the alpha channel.

lRGBBitCount

RGB bits per pixel (4, 8, 16, 24, or 32).

lRGBZBitMask and lYUVZBitMask

Masks for z channel.

lStencilBitDepth

Bit depth of the stencil buffer. This member specifies how many bits are reserved within each pixel of the z-buffer for stencil information (the total number of z-bits is equal to lZBufferBitDepth minus lStencilBitDepth).

lStencilBitMask

Mask for stencil bits within each z-buffer pixel.

lUBitMask

Mask for U bits.

lVBitMask

Mask for V bits.

lYBitMask

Mask for Y bits.

lYUVBitCount

YUV bits per pixel (4, 8, 16, 24, or 32).

lZBitMask

Mask for z bits.

lZBufferBitDepth

Z-buffer bit depth (8, 16, or 24); 32-bit z-buffers are not supported.
