Examples

The following code example shows how to use this property.

This code example is part of a larger example provided for the C1MultiScaleImage class.

public class GcMultiScaleImageDemo : Form
{
	private GcZoom _gcZoomObj;
	private GcMultiScaleImage _gcmultiScaleImage;

	public GcMultiScaleImageDemo()
 	{
		InitializeComponent();

		_gcZoomObj = new GcZoom();
		_gcZoomObj.Target = this;
	}

	private void InitializeComponent()
	{
		ImageItem item1 = new ImageItem();
		item1.Image = Image.FromFile(@"C:\image1.jpg");
		item1.ZoomFactor = 1.5f;

		ImageItem item2 = new ImageItem();
		item2.Image = Image.FromFile(@"C:\image2.jpg");
		item2.ZoomFactor = 2f;

		_gcmultiScaleImage = new GcMultiScaleImage();
		_gcmultiScaleImage.Location = new Point(20, 20);
		_gcmultiScaleImage.Size = new Size(100, 100);
		_gcmultiScaleImage.BackColor = Color.Red;

		_gcmultiScaleImage.ZoomFactor = 1f;
		_gcmultiScaleImage.Image = Image.FromFile(@"C:\image.jpg");
		_gcmultiScaleImage.SizeMode = PictureBoxSizeMode.StretchImage;

		_gcmultiScaleImage.Images.Add(item1);
		_gcmultiScaleImage.Images.Add(item2);

		this.Controls.Add(_gcmultiScaleImage);
	}
}
