如何使用java获取图像高度和宽度？

问题描述

除了使用获取图像的高度和宽度？

Is there any other way besides using ImageIO.read to get image height and width?

因为我遇到了锁定线程的问题。

Because I encounter an issue that locks up the thread.

此错误仅发生在Sun应用服务器上，因此我怀疑它是Sun bug。

This error only occurs on a Sun app server and therefore I suspect that it is a Sun bug.

推荐答案

这里有一些非常简单和方便的东西。

Here is something very simple and handy.

BufferedImage bimg = ImageIO.read(new File(filename));
int width          = bimg.getWidth();
int height         = bimg.getHeight();
