NAME

Flood -- Flood rastport like areafill.

SYNOPSIS

    error = Flood( rp, mode, x, y)
    d0            a1   d2  d0  d1

    BOOL Flood(struct RastPort *, ULONG, SHORT, SHORT);

Links: RastPort

FUNCTION

Search the BitMap starting at (x,y). Fill all adjacent pixels if they are: Mode 0: not the same color as AOLPen Mode 1: the same color as the pixel at (x,y)

When actually doing the fill use the modes that apply to standard areafill routine such as drawmodes and patterns.

INPUTS

rp - pointer to RastPort (x,y) - coordinate in BitMap to start the flood fill at. mode - 0 fill all adjacent pixels searching for border. 1 fill all adjacent pixels that have same pen number as the one at (x,y).

NOTES In order to use Flood, the destination RastPort must have a valid TmpRas raster whose size is as large as that of the RastPort.
