+///
+/// If the image is null, empty, or has an empty name, the function returns immediately.  Otherwise, it creates an ImGui
+/// window with a horizontal scrollbar and menu bar. The image is rendered using the CvMatRender object, resizing it to
+/// fit the available window space.  The raw and rendered dimensions are displayed below the image.
