Declaration

Source position: agraphics.pas line 2348

function Flood(

  Rp: PRastPort;

  Mode: LongWord;

  X: LongInt;

  Y: LongInt

):LongBool;

Arguments

Rp

  

A pointer to RastPort

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).

X

  

X coordinate in BitMap to start the flood fill at.

Y

  

Y coordinate in BitMap to start the flood fill at.

Description

Search the BitMap starting at (x,y). Fill all adjacent pixels if they are:

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

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