Mac 下 GraphicsMagick + im4java 获取图片信息问题

Question

这个是 im4java http://im4java.sourceforge.net/docs/dev-guide.html 文档

以下是官方使用说明

Image Information

Info imageInfo = new Info(filename,true);
System.out.println("Format: " + imageInfo.getImageFormat());
System.out.println("Width: " + imageInfo.getImageWidth());
System.out.println("Height: " + imageInfo.getImageHeight());
System.out.println("Geometry: " + imageInfo.getImageGeometry());
System.out.println("Depth: " + imageInfo.getImageDepth());
System.out.println("Class: " + imageInfo.getImageClass());

在 Mac 下 GraphicsMagick + im4java 获取图片信息问题

package me.dengtao.test;

import java.io.File;

import org.im4java.core.Info;

public class AllTest {

    public static int w(String filename) {
        try {
            Info imageInfo = new Info(filename, true);
            
            System.out.println("Format: " + imageInfo.getImageFormat());
            System.out.println("Width: " + imageInfo.getImageWidth());
            System.out.println("Height: " + imageInfo.getImageHeight());
            System.out.println("Geometry: " + imageInfo.getImageGeometry());
            System.out.println("Depth: " + imageInfo.getImageDepth());
            System.out.println("Class: " + imageInfo.getImageClass());
            
            return 0;
        } catch (Exception e) {
            e.printStackTrace();
            return 0;
        }
    }
    
    public static void main(String[] args) {
        String filename = "/Users/dengtao/Downloads/1.jpg";
        
        File file = new File(filename);
        System.out.println(file.exists());
        
        w(filename);
    }
    
}

运行后面错误

提示应该是文件不存在，可

File file = new File(filename);
System.out.println(file.exists());

确实存在
