编辑我正在使用Eclipse ADT捆绑包但是当我尝试在上面建议的答案中导入库时,它不起作用。
我正在使用LibGDX和Java(90-99%java)的组合来模糊图像。模糊可行,但需要将近一秒的时间来截取,保存,访问,模糊,保存和重新访问它。我无法进行太多的预处理,因为它会让游戏的屏幕截图模糊不清。以下是我目前用于模糊的内容:(如果您需要查看它们,我会将绘图和屏幕截图放好,但我认为问题在于模糊800x480 png。)

public class Blur {
private static BufferedImage mshi;
private BufferedImage databuf;
private static int blurRad = 300;
public static void createBlur(FileHandle file) throws IOException {
mshi = ImageIO.read(file.file());
BufferedImage databuf = new BufferedImage(mshi.getWidth(null),
mshi.getHeight(null),
BufferedImage.TYPE_INT_BGR);
java.awt.Graphics g = databuf.getGraphics();
g.drawImage(mshi, 455, 255, null);
float[] blurKernel = new float[blurRad*blurRad];
for(int i =0; i<blurRad*blurRad; i++) {
blurKernel[i] = 1.0f/256.0f;
}
BufferedImageOp op = new ConvolveOp( new Kernel(20, 20, blurKernel), ConvolveOp.EDGE_ZERO_FILL, null );
mshi = op.filter(mshi, databuf);
g.dispose();
File outputfile = Gdx.files.local("Blur.png").file();
ImageIO.write(mshi, "png", outputfile);
}
