We will start digging into this topic by analyzing the following plugin code. That will give us a nice starting point to introduce the different aspects for developing ImageJ plugins:
import ij.*;
import ij.process.*;
import ij.gui.*;
import java.awt.*;
import ij.plugin.*;
import ij.plugin.frame.*;
public class Test_Plugin implements PlugIn {
public void run(String arg) {
int width = 300;
int height = 300;
ImageProcessor ip = new ByteProcessor(width, height);
ip.setColor(Color.black);
ip.fill();
for(int x = 0; x < width; x++) {
for(int y = 0; y < height; y++) {
if (x == y || (width - x) == y)
ip.putPixel(x, y, 255);
}
}
ImagePlus imp = new ImagePlus("Result image", ip);
imp.show();
}
}First things first: this is a plugin, and not a macro. To edit it, navigate to Plugins | New | Plugin. A sample skeleton will be opened and you just need to fill in the run(arg...
