打开图片获取RGB或者BGR数据后显示图片

CStatic* videoWall = (CStatic*)GetDlgItem(ID_VIDEO_WALL);

显示

       
 CRect rc;
	videoWall->GetWindowRect(&rc);
	int nResult = ::StretchDIBits( videoWall->GetDC()->m_hDC,  
		0,  
		0,  
		rc.Width(),//rc.right - rc.left,  
		rc.Height(),//rc.top,  
		0, m_videoplay->imageFrame->height,  
		m_videoplay->imageFrame->width, -m_videoplay->imageFrame->height,  
		m_videoplay->imageFrame->imageData,  
		m_bmphdr,  
		DIB_RGB_COLORS,  
		SRCCOPY); 

如果图像失真了用如下代码

	CRect rc;
	videoWall->GetWindowRect(&rc);
	HDC hdc = videoWall->GetDC()->m_hDC;
	SetStretchBltMode(hdc, STRETCH_HALFTONE); //必加，StretchBlt, StretchDIBits可以对图像数据进行拉伸, 压缩显示失真
	int nResult = ::StretchDIBits( hdc,  
		0,  
		0,  
		rc.Width(),//rc.right - rc.left,  
		rc.Height(),//rc.top,  
		0, m_videoplay->imageFrame->height,  
		m_videoplay->imageFrame->width, -m_videoplay->imageFrame->height,  
		m_videoplay->imageFrame->imageData,  
		m_bmphdr,  
		DIB_RGB_COLORS,  
		SRCCOPY); 

如果图像显示的是倒着的用如下代码

        
	CRect rc;
	videoWall->GetWindowRect(&rc);
	HDC hdc = videoWall->GetDC()->m_hDC;
	SetStretchBltMode(hdc, STRETCH_HALFTONE); //必加，StretchBlt, StretchDIBits可以对图像数据进行拉伸, 压缩显示失真

	int nResult = ::StretchDIBits( hdc,
		0, 0,
		rc.Width(),
		rc.Height(),
		0, m_videoplay->imageFrame->height,
		m_videoplay->imageFrame->width, -m_videoplay->imageFrame->height,
		m_videoplay->imageFrame->imageData, m_bmphdr, DIB_RGB_COLORS, SRCCOPY);
