creating a multipoint selection - problem

[Jeremy Adler]

The makeSelection(type,xcoord,ycoord) command fails to create a multipoint selection.
The code below is happy to create a segment line(type 6) but changing the type to a 10 (point) fails.

However an earlier version of ImageJ 1.51k - allows the creation of type10 multipoint selection.

roiManager("reset");
xArray=newArray(10,20,30,40,50,60);
yArray=newArray(40,90,120,7,55,56);
makeSelection(6, xArray, yArray);//segmented line
roiManager("Add");

makeSelection(10, xArray, yArray);//point
roiManager("Add");

A far as I can see you have to use

makeSelection("point", xArray, yArray);

This regression is fixed in the latest ImageJ daily build (1.52q24), or work around it by using

   makeSelection("point", xArray, yArray);

When using the “point” type you can add size, color and type properties, for example:

  newImage("New", "RGB ramp", 100, 100, 1);
  run("Set... ", "zoom=400");
  xpoints = newArray(10,20,30,40,50,60);
  ypoints = newArray(40,90,120,7,55,56);
  makeSelection("point small yellow hybrid",xpoints,ypoints);
  rename("small yellow hybrid"); wait(2000);
  makeSelection("point large yellow hybrid",xpoints,ypoints);
  rename("large yellow hybrid"); wait(2000);
  makeSelection("point extra large yellow hybrid",xpoints,ypoints);
  rename("extra large yellow hybrid"); wait(2000);
  makeSelection("point large red cross",xpoints,ypoints);
  rename("large red cross"); wait(2000);
  makeSelection("point extra large red cross",xpoints,ypoints);
  rename("extra large red cross"); wait(2000);
  makeSelection("point extra large white circle",xpoints,ypoints);
  rename("extra large white circle"); wait(2000);
  makeSelection("point extra large cyan dot label",xpoints,ypoints);
  rename("extra large cyan dot label");
