;----------------------------------------------------------------------------; General Comments:; The DIB Engine is non-palettized from GDI's perspective. When an app; selects a DIB into a memory DC, GDI will create a DIB Engine PDevice ; (see definition below) and will stuff in a 'DI' in the deType field.; Subsequent operations on this DC will result in calls to the DIB Engine; with this PDevice. ; Device drivers can also use the DIB Engine to handle most, if not all,; of their rendering work. A device driver exports the DIB Engine PDevice; as it's own PDevice to GDI. This PDevice contains a pointer to a ; BitmapInfo header in the driver's data segment. Immediately following; this is an optional color table for devices less than 16 bpp.;----------------------------------------------------------------------------;----------------------------------------------------------------------------; E Q U A T E S;----------------------------------------------------------------------------BRUSHSIZE equ 8 ;height and width in pixels.VER_DIBENG equ 400h ;version = 4.0comment ~*/#define BRUSHSIZE 8#define VER_DIBENG 0x400/*end comment ~;----------------------------------------------------------------------------; S T R U C T U R E S;----------------------------------------------------------------------------
