The following three JavaScript functions and one PHP script (downloadLocal.php) are used to implement this feature. You can find the php script in the Samples directory by downloading the trial version. (This feature is not supported in IE7,8.)
function GetSnapshot () {
var base64src = document.getElementById("chart1").getSnapshot();
var data = document.getElementById("data");
var extension = document.getElementById("extension");

extension.value = "png";
data.value = base64src;
document.getElementById("sumForm").submit();
}

function saveAsImage () {
KoolChart.downloadToLocal("KoolChart", "png", "https://www.koolchart.com/snapshotSample/downloadLocal.php", function() {
return document.getElementById("chart1").saveAsImage();
});
}

function saveAsPDF () {
KoolChart.downloadToLocal("KoolChart", "pdf", "https://www.koolchart.com/snapshotSample/downloadLocal.php", function(){
return document.getElementById("chart1").getSnapshot("jpeg");
}, (function(){
var holder = document.getElementById("chartHolder"),
width = holder.offsetWidth,
height = holder.offsetHeight;
return {portrait : width < height, size : {width : width, height : height}};
})());
}
