Drawing a mat picture not correct in hdc of C++

C++

Hi,
I create a function like that (below)in C++ to draw a mat picture to HDC. I have use imshow to check and both image and cvImgTmp has been show correctly.
But my final picture look like that
image
I think I do something wrong with “bitInfo” or “SetDIBitsToDevice”
Are there anyone can help me to fix this.

Thank you


void DrawMatToHDC(const char* DicomPath, HDC hdc, RECT rc)// Developing
	{
		DicomImage DCM_image(DicomPath);
		DCM_image.setWindow(0);
		cv::Mat image(int(DCM_image.getWidth()), int(DCM_image.getHeight()), CV_8U, (uchar*)DCM_image.getOutputData(8));

		cv::Size winSize(rc.right, rc.bottom);
		//imshow("DICOM Image Example", image);
		// Resize the source to the size of the destination image if necessary
		cv::Mat cvImgTmp(winSize, CV_8UC3);
		if (image.size() != winSize)
		{
			cv::resize(image, cvImgTmp, winSize);
			
		}
		else
		{
			cvImgTmp = image.clone();
		}
		//imshow("DICOM Image Example", cvImgTmp);
		// Rotate the image
		cv::flip(cvImgTmp, cvImgTmp, 0);

		// Initialize the BITMAPINFO structure

		bitInfo.bmiHeader.biBitCount = 24;
