| BRUSHOBJ_pvAllocRbrush | This function allocates memory that the display driver requires for realization of a specified brush. |
| BRUSHOBJ_pvGetRbrush | This function retrieves a pointer to the realization of a specified brush. |
| CLIPOBJ_bEnum | This function enumerates a batch of rectangles from a specified clip region. A prior call to the CLIPOBJ_cEnumStart determines the order of enumeration. |
| CLIPOBJ_cEnumStart | This function sets parameters for enumerating rectangles in a specified clip region. |
| EngCreateDeviceBitmap | This function requests GDI to create a handle to a bitmap image. |
| EngCreateDeviceSurface | This function creates and returns a handle to a surface that the driver manages. |
| EngCreatePalette | This function sends a request to GDI to create a palette. |
| EngDeleteSurface | This function deletes a specified surface. |
| PALOBJ_cGetColors | This function copies colors from an indexed palette. |
| PATHOBJ_bEnum | This function retrieves the next record from a PATHDATA structure for a specified path and enumerates the curves in the path. |
| PATHOBJ_vEnumStart | This function notifies a specified PATHOBJ structure that the driver is to call the PATHOBJ_bEnum function to enumerate lines or curves in the path. |
| PATHOBJ_vGetBounds | This function retrieves the bounding rectangle for the specified path. |
| XLATEOBJ_cGetPalette | This function retrieves colors from a specified palette or the bitfields format of the palette. |
