如何在Java中保存我的屏幕截图 [英] How To Save My Screenshot in java
问题描述
我正在制作一个需要截图的程序,所以我想拥有一个带有动作监听器的JButton,当按下该按钮时,它将图像保存到某个文件夹(如果该文件夹尚不存在的话)。
这是我认为应该做的:
@Override
public void actionPerformed(ActionEvent arg0){
File dir = new File( C:// SnippingTool + / + date.getDay());
dir.mkdirs();
try {
ImageIO.write(shot, JPG,dir);
} catch(IOException e){
e.printStackTrace();
}
}
});
我认为这与我的 File dir = new File
,而且我没有保存到正确的位置。
这是我的机器人
截图:
try {
shot = new Robot()。createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit( ).getScreenSize()));
} catch(HeadlessException e1){
e1.printStackTrace();
} catch(AWTException e1){
e1.printStackTrace();
}
问题,如我所见就是这两行...
文件目录=新文件( C:// SnippingTool + / +日期。 getDay());
dir.mkdirs();
现在这表示当<$ c $时,您要写入的输出是目录c> ImageIO 正在等待文件,这将失败...
相反,请尝试类似...
文件输出=新文件( C:// SnippingTool + / + date.getDay()+ .jpg);
文件目录= output.getParentFile();
if(dir.exists()|| dir.mkdirs()){
try {
ImageIO.write(shot, JPG,输出);
} catch(IOException e){
e.printStackTrace();
}
} else {
System.out.println( Bad Path- + dir);
}
I'm making a program that takes a screenshot and I want to have it so that i have a JButton with an actionlistener that when pressed it saves the image to a certain folder that if does not already exists it makes.
here is what I thought I should do:
@Override
public void actionPerformed(ActionEvent arg0) {
File dir = new File("C://SnippingTool+/" + date.getDay());
dir.mkdirs();
try {
ImageIO.write(shot, "JPG", dir);
} catch (IOException e) {
e.printStackTrace();
}
}
});
I think it has something to do with my File dir = new File
and that I am not saving to to the right place.
Here is my Robot
taking a screenshot:
try {
shot = new Robot().createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));
} catch (HeadlessException e1) {
e1.printStackTrace();
} catch (AWTException e1) {
e1.printStackTrace();
}
The problem, as I see it is with these two lines...
File dir = new File("C://SnippingTool+/" + date.getDay());
dir.mkdirs();
This now means that the output you are trying to write to is a directory, when ImageIO
is expecting a file, this will fail...
Instead try something like...
File output = new File("C://SnippingTool+/" + date.getDay() + ".jpg");
File dir = output.getParentFile();
if (dir.exists() || dir.mkdirs()) {
try {
ImageIO.write(shot, "JPG", output);
} catch (IOException e) {
e.printStackTrace();
}
} else {
System.out.println("Bad Path - " + dir);
}
