所以我試圖在大學裏爲一個項目製作一個小遊戲。我有一個圖像類加載圖像等我知道這個類的作品,因爲我測試了它,當我做到了。但後來我決定使用一個表單製造商,在這種情況下,WindowsBuilder Pro製作的表單更好,然後我就可以編寫代碼。我現在試圖調用一個函數,理論上它會加載調用圖像類並加載圖像,然後將該圖像作爲圖像添加到jPanel中的標籤。但我什麼都沒有。任何幫助?ImageIcon無法加載
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();
}
這裏是圖片的功能,我使用:
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;
}
}
可能有助於告訴你,佈局框架/面板是grouplayout,並且BGImage是我在WYSIWUG編輯器WBP中添加的標籤。該標籤的寬度爲501,高度爲250或接近。 – Tempus35
將你的圖片放到你的src文件夾中,試試這個^^: ClassLoader cldr = this.getClass()。getClassLoader(); java.net.URL imageURL = cldr.getResource(「path/to/your/images/picture.gif」); ImageIcon imgIcon = new ImageIcon(imageURL); – hungneox
請學習java命名約定並堅持使用它們 – kleopatra
