所以我正在尝试为大学的一个项目制作一个小游戏。我有一个加载图像等的图像类。我知道这个类有效,因为我在制作它时对它进行了全部测试。但后来我决定使用表单制作器,在本例中是 WindowsBuilder Pro 制作的表单,它比我可以编写的代码更好。我现在正在尝试调用一个函数,该函数理论上将加载调用图像类并加载图像,然后将该图像作为图像图标添加到 jPanel 内的标签中。但我什么也没得到。有什么帮助吗?
private void loadres(){
String PROGRAM_DIRECTORY = "E:/WordGame/bin/Images/";
Functions.Resources rs = new Functions.Resources();
rs.loadResources();
Functions.ImageLib iL = rs.getIL();
try {
BGImage = new JLabel(new ImageIcon(iL.mergeImages(iL.getImageArray(0),iL.getImage(PROGRAM_DIRECTORY + "Astroid1Image.png"))));
} catch (IOException e) {
e.printStackTrace();
}
BGImage.revalidate();
BGImage.repaint();
}
这是我正在使用的图像功能:
public class ImageLib {
private ArrayList<BufferedImage> BIArray = new ArrayList<BufferedImage>();
public ImageLib(){
}
public BufferedImage getImage(String ref){
BufferedImage Bi = null;
try{
Bi = ImageIO.read(new File(ref));
}catch (Exception e) {
e.printStackTrace();
}
return Bi;
}
public BufferedImage resizeImage(BufferedImage Bi, int nW, int nH){
int w = Bi.getWidth();
int h = Bi.getHeight();
BufferedImage nBi = new BufferedImage(nW, nH, Bi.getType());
Graphics2D g = nBi.createGraphics();
g.setRenderingHint(RenderingHints.KEY_INTERPOLATION, RenderingHints.VALUE_INTERPOLATION_BILINEAR);
g.drawImage(Bi,0,0,nW,nH,0,0,w,h,null);
g.dispose();
return nBi;
}
public void addToArray(BufferedImage img){
BIArray.add(img);
}
public BufferedImage getImageArray(int index){
return (BufferedImage) BIArray.get(index);
}
public BufferedImage mergeImages(BufferedImage I1, BufferedImage I2) throws IOException{
int w = Math.max(I1.getWidth(), I2.getWidth());
int h = Math.max(I1.getHeight(), I2.getHeight());
BufferedImage combined = new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB);
Graphics g = combined.getGraphics();
g.drawImage(I1, 0, 0, null);
g.drawImage(I2, 0, 0, null);
g.dispose();
return combined;
}
}
