WinForms: Scroll WinForms viewer to the focused image programmatically.

Post by Alex »

This topic contains C# code snippet that allows to scroll WinForms viewer to the focused image programmatically: 
// disable the autoscrolling to the focused image
imageViewer1.DisableAutoScrollToFocusedImage();
// move focus to the next image
imageViewer1.FocusedIndex = imageViewer1.FocusedIndex + 1;
// enable the autoscrolling to the focused image
imageViewer1.EnableAutoScrollToFocusedImage();

// get focused image
VintasoftImage image = imageViewer1.Images[imageViewer1.FocusedIndex];
// get viewer state of focused image
ImageViewerState viewerStateForImage = imageViewer1.GetViewerState(image);
// get image rectangle in viewer space
System.Drawing.RectangleF imageRectInViewer = viewerStateForImage.ImageRectInViewer;
// scroll viewer to the image rectangle
imageViewer1.ScrollToRect(imageRectInViewer);
