ViewX and ViewY specify the top-left of the image that is visible in the TImageEnView component window. Use ViewX/Y to programmatically scroll images bigger than the TImageEnView.
Values are specified in terms of the bitmap.
ImageEnView1.ViewX := 20; // View from pixel column 20 of bitmap (i.e. first 20 pixels on the left of the image will no longer be visible)
ImageEnView1.Zoom := 200; // zoom image to 200% ImageEnView1.ViewX := 20; // view from pixel column 40 of bitmap (i.e. first 40 pixels on the left 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;
