Hi Ethan,
Yes, you'll need to to this line
if (getPixel(i,j ) >= Threshold){
Also, if you want the search to start at the bottom, you may need to change
the inner loop to something like the following. You should also remove the
semicolons at the end of the for loops.
for(j=511; j>=0; j--) { // start at the bottom edge
And then you would also need to change the run("Specify...) line.
That seems pretty slow. May I suggest replacing the specify and fill with
another loop to set the pixels to zero.
for(k=511; k>=j; k--) {
setPixel(i,k,0);
}
Best of luck,
George
