+FusionCharts PHP Export Handler
+==================================
+
+What is FusionCharts PHP 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 server-side, you need a server-side helper library to convert the SVG to image/PDF.
+These export handlers allow you to take the SVG/base64imageData 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 or generate base64 image (only for modern browser and FusionCharts v 3.11.0 or above) 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
+InkScape & ImageMagick if required 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.
+
+Version
+=======
+
+4.0
+
+Requirements
+============
+
+Inkscape and ImageMagick is only required for FusionCharts lower version then 3.11.0.
+For FusionCharts v 3.11.0 and higher if using older browser (IE < 10) which doesnot support base64 encoding and decoding.
+
+Inkscape:
+
+Inkscape is an open source vector graphics editor. What sets Inkscape apart is its use of Scalable Vector Graphics
+(SVG), an open XML-based W3C standard, as the native format. Inkscape has a powerful command line interface and can
+be used in scripts for a variety of tasks, such as exporting and format conversions. For details, refer to the
+following page.

+
+
+ImageMagick:
+
+ImageMagick is a free and open-source software suite for displaying, converting, and editing raster image and vector
+image files. The software mainly consists of a number of command-line interface utilities for manipulating images.
+For further details, please refer to the the following page.

+
+Installation
+============
+
+1. Place the files in the server folder from where the index.php can be accessed.
+2. Give write permission to the folder 'temp' and 'ExportedImages' (create if not there);
+3. If using older FusionCharts (< 3.11.0) or using older browser (IE < 10) install Inkscape and ImageMagick, check the path is same as the file inside Resources have.
