在zbar二维码解码器中使用opencv代替imagemagick

我正在使用 Zbar api 编写一个二维码解码器。我正在使用 Windows 预建库。我使用以下代码将图像加载到 ZBar

IplImage *src=cvLoadImage("image.png",CV_LOAD_IMAGE_GRAYSCALE);
ImageScanner scanner;
scanner.set_config(ZBAR_NONE, ZBAR_CFG_ENABLE, 1);  
int width = src->width;
int height = src->height;   
uchar* raw = (uchar *)(src->imageData);
Image image(width, height, "Y800", raw, width * height);
int n = scanner.scan(image);

但无法解码图像。我是否使用正确的方法使用 opencv 读取图像数据？。当我只测试一张图像时，所有其他图像均已解码并失败。但当我使用 zbarimg 命令行选项时它运行良好

I am writing a qr code decoder using Zbar api. I am using windows pre built libraries . I used the following code to load the image to ZBar

IplImage *src=cvLoadImage("image.png",CV_LOAD_IMAGE_GRAYSCALE);
ImageScanner scanner;
scanner.set_config(ZBAR_NONE, ZBAR_CFG_ENABLE, 1);  
int width = src->width;
int height = src->height;   
uchar* raw = (uchar *)(src->imageData);
Image image(width, height, "Y800", raw, width * height);
int n = scanner.scan(image);

But it failed to decode the image. Am I using the correct way to read image data using opencv ? . When I tested only one image decoded and failed for all others . But it is working well when I used the zbarimg command line option
