image - 如何将“opencv::Mat”转换为“podofo::PdfImage”？

Question

我不知道如何转换opencv::Mat或podofo::PdfImage如何解决崩溃。我很困惑。

我的代码：

// Mat img
// ...do something to init 'img'...
int image_size = img.cols * img.rows;
unsigned char* outBuffer = new unsigned char[image_size];
memcpy(outBuffer, sub_img[0].data, image_size);
//imwrite(".\\71253_0_0.png",img); // can be saved and displayed correctly

PdfImage pdfimg( &document );
pdfimg.LoadFromData(img.data,image_size); **//cause a crash**
