Members
lprDest
Pointer to a RECT structure that defines the destination for the blit.
lpDDSSrc
Pointer to a DirectDrawSurface that will be the source of the blit.
lprSrc
Pointer to a RECT structure that defines the source rectangle of the blit.
dwFlags
| Flag | Description |
| DDBLT_ALPHADEST | Use the alpha information in the pixel format or the alpha channel surface attached to the destination surface as the alpha channel for this blit. |
| DDBLT_ALPHADESTCONSTOVERRIDE | Use the dwConstAlphaDest member in the DDBLTFX structure as the alpha channel for the destination surface for this blit. |
| DDBLT_ALPHADESTNEG | The NEG suffix indicates that the destination surface becomes more transparent as the alpha value increases. (0 is opaque) |
| DDBLT_ALPHADESTSURFACEOVERRIDE | Use the lpDDSAlphaDest member in the DDBLTFX structure as the alpha channel for the destination for this blit. |
| DDBLT_ALPHAEDGEBLEND | Use the dwAlphaEdgeBlend member in the DDBLTFX structure as the alpha channel for the edges of the image that border the color key colors. |
| DDBLT_ALPHASRC | Use the alpha information in the pixel format or the alpha channel surface attached to the source surface as the alpha channel for this blit. |
| DDBLT_ALPHASRCCONSTOVERRIDE | Use the dwConstAlphaSrc member in the DDBLTFX structure as the alpha channel for the source for this blit. |
| DDBLT_ALPHASRCNEG | The NEG suffix indicates that the source surface becomes more transparent as the alpha value increases. (0 is opaque) |
| DDBLT_ALPHASRCSURFACEOVERRIDE | Use the lpDDSAlphaSrc member in the DDBLTFX structure as the alpha channel for the source for this blit. |
| DDBLT_ASYNC | Do this blit asynchronously through the FIFO in the order received. If there is no room in the hardware FIFO fail the call. |
| DDBLT_COLORFILL | Uses the dwFillColor member in the DDBLTFX structure as the RGB color to fill the destination rectangle on the destination surface with. |
| DDBLT_DDFX | Uses the dwDDFX member in the DDBLTFX structure to specify the effects to use for the blit. |
| DDBLT_DDROPS | Uses the dwDDROPS member in the DDBLTFX structure to specify the ROPS that are not part of the Win32 API. |
| DDBLT_KEYDEST | Use the color key associated with the destination surface. |
| DDBLT_KEYDESTOVERRIDE | Use the dckDestColorkey member in the DDBLTFX structure as the color key for the destination surface. |
| DDBLT_KEYSRC | Use the color key associated with the source surface. |
| DDBLT_KEYSRCOVERRIDE | Use the dckSrcColorkey member in the DDBLTFX structure as the color key for the source surface. |
| DDBLT_ROP | Use the dwROP member in the DDBLTFX structure for the raster operation for this blit. These ROPs are the same as the ones defined in the Win32 API. |
| DDBLT_ROTATIONANGLE | Use the dwRotationAngle member in the DDBLTFX structure as the angle (specified in 1/100th of a degree) to rotate the surface. |
| DDBLT_ZBUFFER | Z-buffered blit using the z-buffers attached to the source and destination surfaces and the dwZBufferOpCode member in the DDBLTFX structure as the z-buffer opcode. |
| DDBLT_ZBUFFERDESTCONSTOVERRIDE | Z-buffered blit using the dwConstDest member and the dwZBufferOpCode member in the DDBLTFX structure as the z-buffer and z-buffer opcode respectively for the destination. |
| DDBLT_ZBUFFERDESTOVERRIDE | Z-buffered blit using the lpDDSDestZBuffer member and the dwZBufferOpCode member in the DDBLTFX structure as the z-buffer and z-buffer opcode respectively for the destination. |
| DDBLT_ZBUFFERSRCCONSTOVERRIDE | Z-buffered blit using the dwConstSrcZ member and the dwZBufferOpCode member in the DDBLTFX structure as the z-buffer and z-buffer opcode respectively for the source. |
| DDBLT_ZBUFFERSRCOVERRIDE | Z-buffered blit using the lpDDSSrcZBuffer member and the dwZBufferOpCode member in the DDBLTFX structure as the z-buffer and z-buffer opcode respectively for the source. |
lpDDBltFx
Pointer to a DDBLTFX structure specifying additional blit effects.
