摆动错误：太阳。awt。形象ToolkitImage无法转换为java。awt。形象缓冲图像

Question

请帮我做这件事对我有好处。awt。形象ToolkitImage无法转换为java。awt。形象缓冲图像

 if (shape.hasImage())
                    {
                        // If this shape is an image, extract image to file
                        String extension = ImageTypeToExtension(shape.getImageData().getImageType());
                        String imageFileName = MessageFormat.format("Image.ExportImages.{0} Out.{1}", imageIndex, extension);
                        String strBarCodeImageExtracted = "" + imageFileName;
                        shape.getImageData().save(strBarCodeImageExtracted);

                        // Recognize barcode from this image
                        BarCodeReader reader = new BarCodeReader ((BufferedImage) Toolkit.getDefaultToolkit().getImage(strBarCodeImageExtracted),BarCodeReadType.Code39Standard);
                        while (reader.read())
                        {
                            System.out.println("codetext: " + reader.getCodeText());
                        }
                        imageIndex++;
                    }

编辑：这个答案是在写下评论后被接受的，所以我们必须假设评论是实际的解决方案。评论是

... to replace Toolkit.getDefaultToolkit().getImage(...) with ImageIO.read(...) ...

原始答案：

您可以尝试用^ {CD1>}直接读取图像，或者考虑将图像绘制成新分配的缓冲区，例如使用类似于

的方法。

public static BufferedImage convertToBufferedImage(Image image)
{
    BufferedImage newImage = new BufferedImage(
        image.getWidth(null), image.getHeight(null),
        BufferedImage.TYPE_INT_ARGB);
    Graphics2D g = newImage.createGraphics();
    g.drawImage(image, 0, 0, null);
    g.dispose();
    return newImage;
}

然后在你的情况下：

Image image = Toolkit.getDefaultToolkit().getImage(strBarCodeImageExtracted);
BufferedImage bufferedImage = convertToBufferedImage(image);
BarCodeReader reader = new BarCodeReader(bufferedImage,BarCodeReadType.Code39Standard);
