Parameters

item
The item within the RasterImageList whose bounding rectangle you want to retrieve.

Return Value

A System.Drawing.Rectangle that represents the bounding rectangle of the specified RasterImageListItem.

Example

This example will highlight the position of all visible items a RasterImageList control.

using Leadtools.WinForms; 
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Drawing; 
 
public void RasterImageList_GetItemRectangle(RasterImageList imageList) 
{ 
   // Loop through all items 
   foreach (RasterImageListItem item in imageList.Items) 
   { 
      // Get the item bounding rectangle 
      Rectangle rc = imageList.GetItemRectangle(item); 
 
      // If this rectangle is visible, highlight it 
      if (imageList.ClientRectangle.IntersectsWith(rc)) 
      { 
         // Convert the rectangle to screen coordinates 
         rc = imageList.RectangleToScreen(rc); 
         ControlPaint.DrawReversibleFrame(rc, Color.Transparent, FrameStyle.Thick); 
      }
