This example shows some property settings you might want to make prior to displaying an image.

void CImgEdit1Dlg::OnLoadEditctrl1(double Zoom) 
{
    // Here are some examples of default settings you might
    // want to specify prior to displaying an image.
    // Repaint any changes immediately (ex. zoom or resolution
    // changes, etc.)
    ImgEdit1.SetAutoRefresh(TRUE);
    
    // ScrollBars already default to true, but this is
    // modifiable if desired
    ImgEdit1.SetScrollBars(TRUE);
    
    // Scale black and white images to grayscale.  Keep color image
    // displayed as color images.
    ImgEdit1.SetDisplayScaleAlgorithm(4);   // wiScaleOptimize
    
    // Allow user to scroll image using keyboard shortcuts
    ImgEdit1.SetScrollShortcutsEnabled(TRUE);
    
    // Display all OCR zones
    ImgEdit1.SetOcrZoneVisibility(3);  // wiOcrShowAllZones  // 3
