CImg library contains CImgDisplay to display CImg images. How can I load an image using CImg and display in a CWnd derived class in my MFC application?

i am dealing with the image using cv::Mat structure and i assume that in xaml using tag to display the result image
i try searching using some keywords(ex, uwp, c++, openCV, MAT, Bitmapimage, .etc) but i could not find appropriate solution
is there any solution? or other proper approach?

How to save MFC CImage in a .WMF file? If I use CImage.Save method to save it in .WMF format I am getting the error "save failed:80004005 - Unspecified error".
Is there any other way to save MFC CImage in .WMF format?
Thanks in advance.
The CImage does not support vector graphics like Enhanced Metafile Format (EMF) and Windows Metafile Format (WMF) by design. It is just a wrapper class around Image class from GDI+ that does support raster image formats only: JPEG, GIF, BMP, and Portable Network Graphics (PNG) formats.
Here is the way to save EMF/WMF files based on GDI+:
Bitmap* pBitmap;
...
// do some paintings on pBitmap
...
CStringW sFileName = L"c:\\Files\Image.emf";
CDC* pDC = GetDC();
Metafile* pMetaFile = new Metafile(sFileName, pDC->m_hDC);
Graphics graphics(pMetaFile);
graphics.DrawImage(pBitmap, 0, 0, pBitmap->GetWidth(),
pBitmap->GetHeight());
I have a WICBitmap that contains an image in my MFC program. Is there any way to draw this bitmap onto a device context?
void DrawBitmap(IWICBitmapSource source, HDC targetDC, int X, int Y, int cx, int cy)
{
//source: The Bitmap to draw
//TargetDC: The HDC to draw onto (e.g. a printer or screen DC)
//X,Y: The location on the DC to draw the bitmap
}
There are a number of samples on MSDN that show how to display a WIC bitmap using, for example, GDI, GDI+, Direct2D etc.
MSDN: Image Decoding Samples (archive)
Introduction to WIC: How to use WIC to load an image, and draw it with GDI? (archive)
Microsoft provides a WIC Image Viewer Using GDI Sample (GitHub mirror)
The basic idea is:
convert IWicBitmapSource into a standard Windows BITMAP (CreateDibSectionFromBitmapSource)
draw using the BITMAP using your standard tools
The file can be edited separately as bmp file, and after you can load WIC object as you can see in How to Load a Bitmap from a File.
I want to display an IPLimage / MAT (opencv) formats on a MFC picture box in Visual C++
Here is a complete solution describing how to display an IplImage in a MCF/C++ form application using OpenCV http://ac-it.pl/display-an-iplimage-in-a-mcfc-form-application-using-opencv
Picture boxes can only display bitmaps I think. You'll need to convert IPLimage to a bitmap.
Assuming you can first convert IPLimage to a buffer of RGB values, see Creating HBITMAP from memory buffer
Then when you get the HBITMAP, you'll need to load it in the Picture Box. Assuming by picture box you mean a static control, add SS_BITMAP to its styles, and then load the HBITMAP using
SendMessage(hStatic, STM_SETIMAGE, (WPARAM)IMAGE_BITMAP, (LPARAM)hBitmap);
