The video hardware might also contain a hardware blitter. You can determine the blitting capabilities of the hardware from theDDCAPSstructure obtained in thelpDDDriverCapsparameter of theIDirectDraw::GetCapsmethod. If thedwCapsmember contains DDCAPS_BLT, the hardware has at least minimal blitting...

Enumerates blitting options. This enumeration supports a bitwise combination of its member values. C# [ObjCRuntime.Introduced(ObjCRuntime.PlatformName.iOS,9,0, ObjCRuntime.PlatformArchitecture.All, null)] [ObjCRuntime.Introduced(ObjCRuntime.PlatformName.MacOSX,10,11, ObjCRuntime.PlatformArchitectu...
Transparent blitting enables you to create the illusion of nonrectangular blits when animating sprites. A sprite image is usually nonrectangular, but blits are always rectangular, so every pixel within the sprite's bounding rectangle becomes part of the data transfer.With transparent blitting, each...
Blitting effects include the standard raster operations (ROPs) used by GDI functions such asBitBlt. The only ROPs supported by the HEL are SRCCOPY (the default), BLACKNESS, and WHITENESS. Hardware support for other ROPs can be examined in theDDCAPSstructure for the driver. If you want to ...
Alpha Blitting is a combination of alpha blending and color keying performed with theIDirectDrawSurface::AlphaBltmethod. It is primarily used to composite a source foreground image onto a destination background image while preserving alpha channel information. ...
