Java：从文件加载图像，编辑并添加到JPanel

问题描述

我想将计算机中的图像加载到2D图形中，以便我可以在之后编辑它，然后我想将其添加到 JPanel 。如果您需要查看我的项目，我可以将其发送给您。

I want to load an image from my computer into 2D Graphics so that I can edit it afterwards and then I want to add it to JPanel. If you need to see my project I can send it to you.

void loadImage()
{

    FileDialog fd = new FileDialog(new Frame(), "Please choose a file:", FileDialog.LOAD);
    fd.show();
    if (fd.getFile() != null)
    {
        File fil = new File(fd.getDirectory(), fd.getFile());
        strDirectory = fd.getDirectory();
        strFileType = fd.getFile();
        mainImage.setIcon(new ImageIcon(fil.toString()));
        getFileList(strDirectory);
        checkFileType(strFileType);
    }
}

提前致谢
