ImageIO 无法读取输入文件 [英] ImageIO can't read input file

问题描述

public static void imRes(String pat) {
        try {
            BufferedImage bckimg = ImageIO.read(new File("c:/s/deneme.jpg"));
            File s = new File(pat);
            BufferedImage im = ImageIO.read(s);
            BufferedImage im1 = resIm(im);
            BufferedImage finIm = mergIm(im1, bckimg);
            ImageIO.write(finIm, "jpg", new File("c:/s/deneme1.jpg"));
        } catch (IOException e) {

            e.printStackTrace();
        }

这是我的第一篇文章，如果我做错了什么，请见谅.这段代码运行正常，直到我尝试从源包中读取图像.但现在它无法读取任何图像.我究竟做错了什么?还是与日食有关?

This is my first post, excuse me if I've done something wrong. This code was running properly untill i try to read an image from the source package. But now it can't read any image. What am I doing wrong? Or is it something about eclipse?

异常:

javax.imageio.IIOException: Can't read input file!
    at javax.imageio.ImageIO.read(Unknown Source)
    at imRe.imRes(imRe.java:12)
    at imReTest.main(imReTest.java:6)

谢谢...

推荐答案

如果您使用的是 Windows，请将 / 更改为 \.

Change / for \ if you are using windows.

更跨平台的方法将被替代

A more cross-platform approach would be substitute

C: 用于 File.listRoots()[0] 和每个 / 用于 File.separator.

C: for File.listRoots()[0] and every / for File.separator.

此代码运行正常，直到我尝试从源包中读取图像

This code was running properly untill i try to read an image from the source package

为了从 jar 包中获取文件，必须使用 getClass().getResource() 方法.

In order to get a file from inside your jar package, one must use the getClass().getResource() method.

示例:

application-package:
|-Main.java
|-resources
  |-image.jpg

对于上面的目录结构:

BufferedImage im = ImageIO.read(new File(getClass().getResource("/resources/image.jpg").toURI()));

会成功.
