Example 60 with ByteProcessor

use of ij.process.ByteProcessor in project mcib3d-core by mcib3d.

the class Object3D_IJUtils method createRoi.

public static Roi createRoi(Object3D object3D, int z) {
    // IJ.write("create roi " + z);
    int sx = object3D.getXmax() - object3D.getXmin() + 1;
    int sy = object3D.getYmax() - object3D.getYmin() + 1;
    ByteProcessor mask = new ByteProcessor(sx, sy);
    // object black on white
    // mask.invert();
    draw(object3D, mask, z, 255);
    ImagePlus maskPlus = new ImagePlus("mask " + z, mask);
    // maskPlus.show();
    // IJ.run("Create Selection");
    ThresholdToSelection tts = new ThresholdToSelection();
    tts.setup("", maskPlus);
    tts.run(mask);
    maskPlus.updateAndDraw();
    // IJ.write("sel=" + maskPlus.getRoi());
