J#-改变图片大小
public Image ImageChangeSize(String imageName,int width,int height) { Image img = null; try { File f = new File("src/Image/Software/Plane/"+imageName);//找到文件所在的位置 BufferedImage src = ImageIO.read(f);//把文件读到缓存里去 Graphics g = src.getGraphics();//给缓存添加一支画笔 img = src.getScaledInstance(width,height,BufferedImage.SCALE_SMOOTH);//在缓存里描绘图片的大小 g.drawImage(img,0,0,null);//用画笔画出图片 g.dispose();//销毁画笔 } catch(Exception ex) { ex.getStackTrace(); } return img; }
