TImageEnView.ViewX

Declaration

property ViewX: integer;

Description

ViewX and ViewY specify the top-left of the image that is visible in the TImageEnView component window. Use ViewX/Y to programatically scroll images bigger than the TImageEnView.
Values are specified in terms of the bitmap.

Examples

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;
