The DDGPESurf class extends the GPESurf class. It represents a surface that may have been allocated by GDI, the display driver, or the DDHAL. For a description of the DDGPESurf class, see DDGPESurf Class Definition.
The following table shows the methods defined in the DDGPESurf class.
| Method | Description |
|---|---|
| DDGPESurf::AlignedWidth | Retrieves the width of the memory allocated for a surface. |
| DDGPESurf::Bpp | Determines the number of bits per pixel in the current surface. |
| DDGPESurf::ColorKey | Obtains the color key for the current surface. |
| DDGPESurf::ColorKeyHigh | Retrieves the high color-key value from a surface that uses a range of color keys. |
| DDGPESurf::ColorKeyLow | Retrieves the low color-key value from a surface that uses a range of color keys. |
| DDGPESurf::ColorKeyMask | Retrieves the color-key mask for the current surface. |
| DDGPESurf Constructors | Provides information about the various DDGPESurf object constructors. |
| DDGPESurf::DeleteSurface | Deletes a GPE surface and releases the occupied memory. |
| DDGPESurf::HasAlpha | Determines whether the specified surface has an alpha channel. |
| DDGPESurf::Init | Initializes the pixel format for the current surface. |
| DDGPESurf::GetDDGPESurf | Retrieves the DDGPESurf object associated with a DirectDraw surface. |
| DDGPESurf::GetDirectDrawSurface | Retrieves the DirectDraw surface associated with a DDGPESurf object. |
| DDGPESurf::GetDriverData | Retrieves a pointer to the driver data associated with the current DDGPESurf object. |
| DDGPESurf::GetDriverGUID | Retrieves the driver-specific GUID applied to the current object. |
| DDGPESurf::PixelFormat | Retrieves the DDGPE-stile pixel format for the current surface. |
| DDGPESurf::SetColorKey | Sets the color key for the current surface. |
| DDGPESurf::SetColorKeyHigh | Sets the high value for a range of color keys specific to the specified surface. |
| DDGPESurf::SetColorKeyLow | Sets the low value for a range of color keys specific to the specified surface. |
