public ref class ImageViewer : public ImageViewerBase^

Remarks

ImageViewer allows to:

Preview image using different size modes
Scroll and zoom image
Magnify image
Select rectangular or custom image region
Copy/cut/paste image
Scale to gray (antialiasing) option for black-white images
Enable/disable buffering

Supported size modes:

Normal with screen resolution (ImageSizeMode.Normal)
Normal with image resolution (ImageSizeMode.PixelToPixel)
Best fit (ImageSizeMode.BestFit)
Fit to width (ImageSizeMode.FitToWidth)
Fit to height (ImageSizeMode.FitToHeight)
Scale (ImageSizeMode.Scale)

ImageViewer has the image collection (the Images property) which stores images associated with this viewer.

ImageViewer can work separately (viewer will have own image collection) or as a slave viewer of another viewer (viewer will use the image collection of master viewer).

Example

VB.NET


Class ImageViewerExample
    Private _thumbnailViewer1 As Vintasoft.Imaging.UI.ThumbnailViewer = Nothing
    Private _imageViewer1 As Vintasoft.Imaging.UI.ImageViewer = Nothing

    Public Sub RunExample()
        _thumbnailViewer1.MasterViewer = _imageViewer1
        _imageViewer1.Images.Add("c:\multipage.tiff")
    End Sub
End Class


class ImageViewerExample
{
    Vintasoft.Imaging.UI.ThumbnailViewer _thumbnailViewer1 = null;
    Vintasoft.Imaging.UI.ImageViewer _imageViewer1 = null;

    public void RunExample()
    {
        _thumbnailViewer1.MasterViewer = _imageViewer1;
        _imageViewer1.Images.Add(@"c:\multipage.tiff");
    }
}
