我正在使用这种方法来展示我的BufferedImage:public void setUriFromInpustream(InputStream in) { BufferedImage bimg; try { bimg = ImageIO.read(in); originAspectRatio = (double) bimg.getWidth() / (double) bimg.getHeight(); if (width == 0) width = bimg.getWidth(); if (height == 0) height = bimg.getHeight(); setPreserveOriginAspectRatio(preserveOriginAspectRatio); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); }}和bimg.getWidth()正在bimg.getHeight()向我展示NullPointerException。有什么解决办法吗?
