NAME

ClipBlit -- Calls BltBitMap after accounting for windows

SYNOPSIS

    ClipBlit(Src, SrcX, SrcY, Dest, DestX, DestY, XSize, YSize, Minterm)
             A0   D0    D1    A1    D2     D3     D4     D5     D6

    void ClipBlit
         (struct RastPort *, WORD, WORD, struct RastPort *, WORD, WORD,
          WORD, WORD, UBYTE);

FUNCTION

Performs the same function as BltBitMap, except that it takes into account the Layers and ClipRects of the layer library, all of which are (and should be) transparent to you. So, whereas BltBitMap requires pointers to BitMaps, ClipBlit requires pointers to the RastPorts that contain the Bitmaps, Layers, etcetera.

If you are going to blit blocks of data around via the RastPort of your Intuition Window, you must call this routine (rather than BltBitMap).

Either the Src RastPort, the Dest RastPort, both, or neither, can have Layers. This routine takes care of all cases.

See BltBitMap for a thorough explanation.

INPUTS

Src = pointer to the RastPort of the source for your blit SrcX, SrcY = the topleft offset into Src for your data Dest = pointer to the RastPort to receive the blitted data DestX, DestY = the topleft offset into the destination RastPort XSize = the width of the blit YSize = the height of the blit Minterm = the boolean blitter function, where SRCB is associated with the Src RastPort and SRCC goes to the Dest RastPort
