... possibly you are looking for the macro blanket.txt from Gabriel  
Landini ?

//--------------8<-----------------
// Blanket Transform
// Implements K. Rodenacker's blanquet tranform
// where each pixel in the result represents the
// maximum slice number in which the pixel is set.
// Assumes a binary stack where image=255 and
// the background is 0.
// G. Landini 17/1/2007

run("Divide...", "stack value=255");
s=nSlices();

// run("32-bit");
for (i=2;i<=s;i++) {
  setSlice(i);
  run("Multiply...", "slice value="+i);
}
run("Z Project...", "start=1 stop=" + s + " projection=[Max  
Intensity]");
rename("blanket");
// setMinAndMax(0, s);
run("Fire");
run("Enhance Contrast", "saturated=0");
//--------------8<-----------------
