The physical position and size of the image in pixels (single item mode).

Example

using Leadtools; using Leadtools.Controls; using Leadtools.Codecs; using Leadtools.Drawing; using Leadtools.ImageProcessing; using Leadtools.ImageProcessing.Color; public void GetItemViewBounds_Example() { // Clear all the images already the viewer _imageViewer.Items.Clear(); // Use vertical view layout _imageViewer.ViewLayout = new ImageViewerVerticalViewLayout(); // Make sure the item size is larger than the image size (thumbnails mode) _imageViewer.ItemSize = LeadSize.Create(200, 200); _imageViewer.ItemPadding = new Padding(8, 8, 8, 20); _imageViewer.ImageBorderThickness = 1; // Add 4 items to the viewer using (var codecs = new RasterCodecs()) { for (var page = 1; page <= 4; page++) { var item = new ImageViewerItem(); var fileName = Path.Combine(LEAD_VARS.ImagesDir, string.Format("ocr{0}.tif", page)); // Create a thumbnail from the image using (var image = codecs.Load(fileName, page)) { item.Image = image.CreateThumbnail(180, 180, 24, RasterViewPerspective.TopLeft, RasterSizeFlags.Resample); } item.Text = string.Format("Item {0}", page - 1); _imageViewer.Items.Add(item); } } // Hook to the viewer mouse click event _imageViewer.MouseClick += (sender, e) => { // Loop through each item, get the view bounds of the image (the physical location and size on the viewer surface of the item) // and perform hit-testing foreach (var item in _imageViewer.Items) { // Pass part as image and clipped as true, we are only interested on what we are seeing var bounds = _imageViewer.GetItemViewBounds(item, ImageViewerItemPart.Image, true); // Hit-test. GetItemViewBounds returns the value in the control coordinates, same as the mouse click if (bounds.Contains(e.X, e.Y)) { Debug.WriteLine("Clicked the image of item at index " + _imageViewer.Items.IndexOf(item)); return; } } }; } static class LEAD_VARS { public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; }
