DXDITHERDESC Structure

Contains the information needed by the DXDitherArray helper function to dither an array of samples. You can use dithering to produce the effect of 32-bit and 16-bit color with an 8-bit color palette. The dithering algorithm uses a 4 × 4 dither pattern to produce the output.

Syntax

typedef struct DXDITHERDESC
{
    DXBASESAMPLE *      pSamples;     
    ULONG               cSamples;      
    ULONG               x;           
    ULONG               y;          
    DXSAMPLEFORMATENUM DestSurfaceFmt; 
} DXDITHERDESC;

Members

pSamples
Pointer to the samples to dither onto the output surface.

cSamples
Number of samples in the pSamples buffer to dither.

x
The x-coordinate of the output surface.

y

DestSurfaceFmt
Pixel format of the destination surface.
