FileImageRender Class
Members 


The FileImageRender renders a chart image to the local temporary files and returns the image Url.
Object Model
FileImageRender Class
Syntax
'Declaration
 
Public Class FileImageRender 
   Inherits ImageRender
'Usage
 
Dim instance As FileImageRender
public class FileImageRender : ImageRender 
Remarks
Repeated requests for the same chart use the same file to reduce load on the server. New requests create new files as needed. Files are not cleaned up automatically. FileImageRender is recommended when charts are complex (expensive to generate) or when you expect a large number of requests for a relatively small number of different charts.
