Roi color selection

[ashish ram]

Hello everyone!!!!

I am a new user of ImageJ and I want to know how the roi cal be filled with
a color.
the part of the code i am using for selection is like the following,
*
  ip.setRoi(new OvalRoi(50, 50, 30, 30));
                ip.fill();
                 ip.reset(ip.getMask());
    im.updateAndDraw();
    IJ.wait(1000);
    ip.reset();
im.updateAndDraw(); // redisplay modified imageI
    IJ.wait(1000)
*

But everytime the rio is filled by a black colour but i want to fill it with
different colour (say White).
Please let me know how can it be done in a proper way.

Thank you,
Ashish

Hi Ashish,

the API documentation is at
   http://rsb.info.nih.gov/ij/developer/api/index.html

In the ImageProcessor class, you will find, e.g.,
   setColor(java.awt.Color color)
     Sets the default fill/draw value to the pixel value closest to  
the specified color.

If the API documentation is insufficient, it always pays off to have  
a look at the sources of the current ImageJ version at http://
rsb.info.nih.gov/ij/source/ij/
