Public Attributes | |
| Byte | bReserved |
| Specifies the number of overlay and underlay planes. Bits 0 through 3 specify up to 15 overlay planes and bits 4 through 7 specify up to 15 underlay planes. | |
| Byte | cAccumAlphaBits |
| Specifies the number of alpha bitplanes in the accumulation buffer. | |
| Byte | cAccumBits |
| Specifies the total number of bitplanes in the accumulation buffer. | |
| Byte | cAccumBlueBits |
| Specifies the number of blue bitplanes in the accumulation buffer. | |
| Byte | cAccumGreenBits |
| Specifies the number of green bitplanes in the accumulation buffer. | |
| Byte | cAccumRedBits |
| Specifies the number of red bitplanes in the accumulation buffer. | |
| Byte | cAlphaBits |
| Specifies the number of alpha bitplanes in each RGBA color buffer. Alpha bitplanes are not supported. | |
| Byte | cAlphaShift |
| Specifies the shift count for alpha bitplanes in each RGBA color buffer. Alpha bitplanes are not supported. | |
| Byte | cAuxBuffers |
| Specifies the number of auxiliary buffers. Auxiliary buffers are not supported. | |
| Byte | cBlueBits |
| Specifies the number of blue bitplanes in each RGBA color buffer. | |
| Byte | cBlueShift |
| Specifies the shift count for blue bitplanes in each RGBA color buffer. | |
| Byte | cColorBits |
| Specifies the number of color bitplanes in each color buffer. For RGBA pixel types, it is the size of the color buffer, excluding the alpha bitplanes. For color-index pixels, it is the size of the color-index buffer. | |
| Byte | cDepthBits |
| Specifies the depth of the depth (z-axis) buffer. | |
| Byte | cGreenBits |
| Specifies the number of green bitplanes in each RGBA color buffer. | |
| Byte | cGreenShift |
| Specifies the shift count for green bitplanes in each RGBA color buffer. | |
| Byte | cRedBits |
| Specifies the number of red bitplanes in each RGBA color buffer. | |
| Byte | cRedShift |
| Specifies the shift count for red bitplanes in each RGBA color buffer. | |
| Byte | cStencilBits |
| Specifies the depth of the stencil buffer. | |
| Int32 | dwDamageMask |
| Ignored. Earlier implementations of OpenGL used this member, but it is no longer used. | |
| Int32 | dwFlags |
| A set of bit flags that specify properties of the pixel buffer. The properties are generally not mutually exclusive; you can set any combination of bit flags, with the exceptions noted. | |
| Int32 | dwLayerMask |
| Ignored. Earlier implementations of OpenGL used this member, but it is no longer used. | |
| Int32 | dwVisibleMask |
| Specifies the transparent color or index of an underlay plane. When the pixel type is RGBA, dwVisibleMask is a transparent RGB color value. When the pixel type is color index, it is a transparent index value. | |
| Byte | iLayerType |
| Ignored. Earlier implementations of OpenGL used this member, but it is no longer used. | |
| Byte | iPixelType |
| Specifies the type of pixel data. The following types are defined. | |
| Int16 | nSize |
Specifies the size of this data structure. This value should be set to sizeof(PIXELFORMATDESCRIPTOR). | |
| Int16 | nVersion |
| Specifies the version of this data structure. This value should be set to 1. | |
