Marc,
The following macro draws the axes on the elipses image of analyzed objects.
Sincerely,
Jerome.
//Draw axes on objects elipses
run("Blobs (25K)");
run("Make Binary");
run("Set Measurements...", " min centroid bounding fit shape area_fraction
limit redirect=None decimal=3");
run("Analyze Particles...", "size=0-Infinity circularity=0.00-1.00
show=Ellipses display exclude clear add");
run("RGB Color");
for(i=0; i<nResults; i++) {
x=getResult('X',i);
y=getResult('Y',i);
d=getResult('Major',i);
a = getResult('Angle',i)*PI/180;
setColor("blue");
drawLine(x+(d/2)*cos(a),y-(d/2)*sin(a),x-(d/2)*cos(a),y+(d/2)*sin(a));
d=getResult('Minor',i);
a=a+PI/2;
setColor("red");
drawLine(x+(d/2)*cos(a),y-(d/2)*sin(a),x-(d/2)*cos(a),y+(d/2)*sin(a));
}
// end
