setting selection line-width from a macro

[Martin Höhne]

Dear All,

I want to convert a segmented-line into an area, and repeat this for different line witdths (of the same original segmented line). I can do this manually, but I fail doing this from a macro. Below is a macro which I thought would do this, but it fails. All created areas have the same size.
What am I missing?

Thanks
Martin

-------
run("Dot Blot (7K)");
makeLine(482,48,387,125,246,90,156,175,67,143,54,223);
roiManager("Add");

for (i=1; i<33; i=i+10) {
        roiManager("Select", 0);
        run("Line Width...", "line="+i);
        run("Line to Area");
        roiManager("Add");
}
roiManager("Show All");

The Edit>Options>Line Width… command does not change the width of existing lines. Use Roi.setStrokeWidth(w) instead of run("Line Width...", "line="+w).

-wayne

  run("Dot Blot (7K)");
  run("Line Width...", "line=1");
  makeLine(482,48,387,125,246,90,156,175,67,143,54,223);
  roiManager("Add");
  for (i=1; i<33; i=i+10) {
     roiManager("Select", 0);
     Roi.setStrokeWidth(i);
     run("Line to Area");
     roiManager("Add");
  }
  roiManager("Show All");
