FusionCharts ASP.NET Export Handler
|
|
=====================================
|
|
|
|
What is FusionCharts .NET export handler?
|
|
-----------------------------------------
|
|
FusionCharts Suite XT uses JavaScript to generate charts in the browser, using SVG and VML (for older IE). If you need
|
|
to export the charts as images or PDF, you need a server-side helper library to convert the SVG to image/PDF. These
|
|
export handlers allow you to take the SVG from FusionCharts charts and convert to image/PDF.
|
|
|
|
How does the export handler work?
|
|
---------------------------------
|
|
- A chart is generated in the browser. When the export to image or PDF button is clicked, the chart generates the SVG string
|
|
to represent the current state and sends to the export handler. The export handler URL is configured via chart attributes.
|
|
- The export handler accepts the SVG string along with chart configuration like chart type, width, height etc., and uses
|
|
SharpVectors library to convert to image or PDF.
|
|
- The export handler either writes the image or PDF to disk, based on the configuration provided by chart, or streams it
|
|
back to the browser.
|
|
|
|
|
|
Requirements
|
|
------------
|
|
- .NET Framework 3.5 or higher
|
|
|
|
|
|
Installation
|
|
------------
|
|
- Unzip the 'asp-net-export-handler.zip' in your IIS wwwroot folder (e.g. C:\inetpub\wwwroot)
|
|
- Add an application in your server and set physical path to the above folder
|
|
- Set the URL of 'FCExporter.aspx' from the above web application into the chart's 'exportHandler' attribute
|
|
- Make sure 'IUSR' has proper read/write permission in the 'Exported_Images' folder
|
|
- FusionCharts' export request contains some XML data, which is restricted in .NET 4 or above. You may need to add the following configuration in your 'web.config' file:
|
|
<system.web>
|
|
<httpRuntime requestValidationMode="2.0"/>
|
|
</system.web>
