示例1: run

import ij.process.StackConverter; //导入依赖的package包/类
@Override
public void run(String arg) {
	ImagePlus image = IJ.getImage();
	// compute min
	double min = ImageUtil.minOfImagePlusValues(image);
	if (min < -32000) min = -32000;
	// set minimum to 0;
	ImageUtil.addToImagePlusValues(image, -min);
	// store conversion setting
	boolean scaling = ImageConverter.getDoScaling();
	// turn conversion off
	ImageConverter.setDoScaling(false);
	// convert to 16 bit
	StackConverter convert = new StackConverter(image);
	convert.convertToGray16();
	// set scaling to previous value
	ImageConverter.setDoScaling(scaling);
	// set calibration
	double [] coeff = {min, 1.0};
