Here is a macro that flood fills particles with their circularity. It
requires the v1.41d daily build, which fixes a bug in the setColor()
macro function that caused to always convert the argument to an
integer.
requires("1.41d");
run("Blobs (25K)");
run("Make Binary");
run("Set Measurements...", "area perimeter circularity decimal=3");
run("Analyze Particles...", "show=Nothing clear record");
run("32-bit");
for (i=0; i<nResults; i++) {
x = getResult('XStart', i);
y = getResult('YStart', i);
circularity = getResult('Circ.', i);
setColor(circularity);
floodFill(x, y);
}
run("Select None");
resetMinAndMax;
