Flood Fill

[meastwood98]

Hi all,

Im writing a plug-in for imageJ using Java, Im wanting to simply flood fill a circle with a certain color, i tried using the IJ.setForegroundColor(); and then IJ.floodFill(); commands but the second one came up with an error. Can anyone tell me how to do this, i think this should be easier than it is proving to be!

THank you in advance,
Mark

The IJ class does not have a floodFill() method. The easy way to do
this would be to write a macro. In a plugin, you can use the
FloodFiller class. For an example, download the ImageJ source and look
at the floodFill() method in ij/macro/Functions.java.

I have used in my Binary Reconstruct plugin:

FloodFiller ff = new FloodFiller(ip);
ff.fill8(x, y);
