property ViewY: integer;

ImageEnView1.Zoom  := 200; // zoom image to 200%
ImageEnView1.ViewY := 20;  // view from pixel row 40 of bitmap (i.e. first 40 pixels on the top of the image will no longer be visible)

// Scroll the view to show layer #1
ImageEnView1.ViewX := ImageEnView1.Layers[1].PosX;
ImageEnView1.ViewY := ImageEnView1.Layers[1].PosY;
