Hi Ashish,
the API documentation is at
http://rsb.info.nih.gov/ij/developer/api/index.htmlIn 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/
