问题描述

我正在尝试使用Matlab将屏幕快照保存在特定目录中.我可以生成屏幕截图，但是找不到将其保存在特定目录中的解决方案.我已经尝试过保存和另存为，但收到错误消息...有什么想法吗?非常感谢您的帮助.

I am trying to save a screenshot in a specific directory using Matlab. I am able to generate the screenshot but I find no solution to save it in a specific directory. I have tried save and saveas but get error messages...Any ideas? Really appreciate any help.

robo = java.awt.Robot;
t = java.awt.Toolkit.getDefaultToolkit();
rectangle = java.awt.Rectangle(t.getScreenSize());
image = robo.createScreenCapture(rectangle);
filehandle = java.io.File(sprintf('%s_screencapture.jpg',current_stock));

javax.imageio.ImageIO.write(image,'jpg',filehandle);

dest_dir = 'D:\screenshot\';

推荐答案

这对您有用吗?

filepath = fullfile(dest_dir, sprintf('%s_screencapture.jpg',current_stock));

filehandle = java.io.File(filepath);

javax.imageio.ImageIO.write(image,'jpg',filehandle);

PS-最好不要使用image或rectangle作为变量名，因为它们是内置MATLAB命令的名称.

PS - best not to use image or rectangle as variable names, as they are the names of built-in MATLAB commands.
