Hi, sirs,
I am compiling a java swing program like this:
1. I can input an image from directory;
2. On this image, I can set 256 points for x-axis and 256 points for y-axis,
from (1,1), (1,2)...(256,256);
3. When I click a radio, a fixed point, say (5,6), should be highlighted by
red color;
Right now, steps 1, 2 have been finished. Can anyone tell me how to do the
step 3 ? Or can you give me some clues, such as some websites?
Appreciated !
Thanks.
