   LeadRect get(); 
}

Tile # get  (CodecsLoadImageEventArgs)

Property Value

The rectangular area of the image being loaded. The default value is 0,0,0,0.

Remarks

This is only valid if OffsetValid is true.

This is the same value passed to the Load or LoadAsync methods that take a tile parameter.

Example

using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Color; 
using Leadtools.Svg;

   Debug.WriteLine("The current row in the first line of the buffer is: {0}", e.Row); 
   Debug.WriteLine("The number of lines in the buffer is: {0}", e.Lines); 
 
   if (e.OffsetValid) 
   {
