java - 将图像解析为多个图像

Question

我正在制作一个带有自定义文本图标的游戏，我想从一个图像加载每个图像。如何将一个图像分割成一堆其他图像，这些图像只是原始图像的一部分？

我认为您正在寻找 CropImageFilter

An ImageFilter class for cropping images. This class extends the basic ImageFilter Class to extract a given rectangular region of an existing Image and provide a source for a new image containing just the extracted region

您必须将其与 FilteredImageSource 一起使用

This class is an implementation of the ImageProducer interface which takes an existing image and a filter object and uses them to produce image data for a new filtered version of the original image.

例如

public class Part extends JPanel {
    private Image src;

    public Part(Image src) {
        this.src = src;
    }

    public Image create(int xPos, int yPos, int width, int height) {
        ImageFilter cropImagefilter = new CropImageFilter(xPos, yPos, width, height); //see constructor detail
        FilteredImageSource filteredImageSource = new FilteredImageSource(this.src.getSource(), cropImagefilter)
        Image part = createImage(filteredImageSource);
        return part;
    }
}
