## **Properties**
| **Name** | **Type** | **Access** | **Description** |
| :- | :- | :- | :- |
| b_reserved | System.Byte | r/w | Gets or sets specifies the number of overlay and underlay planes. Bits 0 through 3 specify <br/>            up to 15 overlay planes and bits 4 through 7 specify up to 15 underlay planes |
| c_accum_alpha_bits | System.Byte | r/w | Gets or sets specifies the number of alpha bitplanes in the accumulation buffer |
| c_accum_bits | System.Byte | r/w | Gets or sets specifies the total number of bitplanes in the accumulation buffer. |
| c_accum_blue_bits | System.Byte | r/w | Gets or sets specifies the number of blue bitplanes in the accumulation buffer. |
| c_accum_green_bits | System.Byte | r/w | Gets or sets specifies the number of green bitplanes in the accumulation |
| c_accum_red_bits | System.Byte | r/w | Gets or sets specifies the number of red bitplanes in the accumulation buffer |
| c_alpha_bits | System.Byte | r/w | Gets or sets  Specifies the number of alpha bitplanes in each RGBA color buffer |
| c_alpha_shift | System.Byte | r/w | Gets or sets Specifies the shift count for alpha bitplanes in each RGBA color buffer |
| c_aux_buffers | System.Byte | r/w | Gets or sets specifies the number of auxiliary buffers. Auxiliary buffers are not supported |
| c_blue_bits | System.Byte | r/w | Gets or sets  Specifies the number of blue bitplanes in each RGBA color buffer. |
| c_blue_shift | System.Byte | r/w | Gets or sets  Specifies the shift count for blue bitplanes in each RGBA color buffer. |
| c_color_bits | System.Byte | r/w | Gets or sets the number of bits per pixel for RGBA pixel types, excluding the alpha bitplanes. For color table pixels, it is the size of each color table index |
| c_depth_bits | System.Byte | r/w | Gets or sets specifies the depth of the depth (z-axis) buffer. |
| c_green_bits | System.Byte | r/w | Gets or sets  Specifies the number of green bitplanes in each RGBA color buffer |
| c_green_shift | System.Byte | r/w | Gets or sets  Specifies the shift count for green bitplanes in each RGBA color buffer. |
| c_red_bits | System.Byte | r/w | Gets or sets  Specifies the number of red bitplanes in each RGBA color buffer |
| c_red_shift | System.Byte | r/w | Gets or sets  Specifies the shift count in bits for red bitplanes in each RGBA color buffer. |
| c_stencil_bits | System.Byte | r/w | Gets or sets specifies the depth of the stencil buffer. |
| dw_damage_mask | int | r/w | Gets or sets This field MAY be ignored |
| dw_flags | int | r/w | Gets or sets bit flags that specify properties of the pixel buffer that is used <br/>            for output to the drawing surface. These properties are not all mutually <br/>            exclusive; combinations of flags are allowed, except where noted otherwise. |
| dw_layer_mask | int | r/w | Gets or sets This field MAY be ignored. |
| dw_visible_mask | int | r/w | Gets or sets specifies the transparent color or index of an underlay plane. When the pixel <br/>            type is RGBA, dwVisibleMask is a transparent RGB color value. When the pixel <br/>            type is color index, it is a transparent index value. |
| layer_type | System.Byte | r/w | Gets or sets This field MAY be ignored |
| n_size | int | r/w | Gets or sets a 16-bit integer that specifies the size, in bytes, of this data structure. |
| n_version | int | r/w | Gets or sets a 16-bit integer that MUST be set to 0x0001. |
| pixel_type | System.Byte | r/w | Gets or sets the type of pixel data<br/>            PFD_TYPE_RGBA       0x00 The pixel format is RGBA.<br/>            PFD_TYPE_COLORINDEX 0x01 Each pixel is an index in a color table. |
