cv::Mat pix8ToMat(PIX *pix8)
{
cv::Mat mat(cv::Size(pix8->w, pix8->h), CV_8UC1);
uint32_t *line = pix8->data;
for (uint32_t y = 0; y < pix8->h; ++y) {
for (uint32_t x = 0; x < pix8->w; ++x) {
mat.at<uchar>(y, x) = GET_DATA_BYTE(line, x);
}
line += pix8->wpl;
}
return mat;
}

I know this code can convert the pix into Mat

Pix *p = pixRead("mytif.tif");
Mat mat1 = pix8ToMat(p);

But this code will fail to convert the Pix into Mat

Mat image = imread("danger_module.png", 0);
cvtColor(image, image, CV_GRAY2BGR);
api->SetImage(image.data, image.cols, image.rows, 3, 3 * image.cols);
Pix* page_pix = api->GetThresholdedImage();
Mat mat2 = pix8ToMat(page_pix);

I just can view the page_pix by pixWrite("tessinput.png", page_pix, IFF_PNG); now. I think the question is derive from your pix8ToMat. Help please.
