i'm unable exact image required output when generate pdf. i'm converting svg canvas still i'm unable desired output. instead of exact image black content inside that. css code above 1 is

.bullet {     font: 10 px sans-serif; } .bullet.marker {     stroke: #000;     stroke-width: 2px; } .bullet .tick line {     stroke: # 666;     stroke-width: .5px; } .bullet.range.s0 {     fill: #eee; } .bullet.range.s1 {     fill: #ddd; } .bullet.range.s2 {     fill: #ccc; } .bullet.measure.s0 {     fill: steelblue; } .bullet.measure.s1 {     fill: #fff; } .bullet.measure.s2 {     fill: steelblue; } .bullet.measure.s3 {     fill: lightsteelblue; } .bullet.title {     font-size: 10px;     font-weight: bold; } .bullet.subtitle {     fill: #999; }

the javascript helps me rendering data is

function genpdf(){     var svgelements = $("#page-content-wrapper").find('svg');        //replace svgs temp canvas     svgelements.each(function() {         var canvas, xml;          canvas = document.createelement("canvas");         canvas.classname = "screenshottempcanvas";         // canvas.getcontext("3d");         //convert svg xml string         xml = (new xmlserializer()).serializetostring(this);          // removing name space ie throws error         xml = xml.replace(/xmlns=\"http:\/\/www\.w3\.org\/2000\/svg\"/, '');          //draw svg onto canvas         canvg(canvas, xml);         $(canvas).insertafter(this);         $(this).addclass('temphide');         $(this).hide();     });     html2canvas(document.getelementbyid('page-content-wrapper'), {         onrendered: function (canvas){             var img = canvas.todataurl("image/jpeg",1.0);             var doc = new jspdf();             doc.addimage(img, 'jpeg' , 10, 10);             doc.save('test.pdf');         }     });     settimeout(function(){         $("#page-content-wrapper").find('.screenshottempcanvas').remove();         $("#page-content-wrapper").find('.temphide').show().removeclass('temphide');         $("#page-content-wrapper").find('.bullet').show();     },2000); }  function getstyle(el, styleprop) {     var camelize = function(str) {         return str.replace(/\-(\w)/g, function(str, letter) {             return letter.touppercase();         });     };      if (el.currentstyle) {         return el.currentstyle[camelize(styleprop)];     } else if (document.defaultview && document.defaultview.getcomputedstyle) {         return document.defaultview.getcomputedstyle(el, null)         .getpropertyvalue(styleprop);     } else {         return el.style[camelize(styleprop)];     } }

There are many reasons for this but number one in my opinion is that above all else they put value on content. Today I want to introduce you to two very powerful small business advertising options created by Google. These two ingenious programs have all but revolutionized the way advertising is done on the web. Warning: If you are thinking..."web advertising isn't for me, I just need a few more clients around the block"...you better read this or be prepared to have your competitors eat your lunch. Goolge AdSense - Again content is king at Google. This program allows web site "publishers" to add some code from Google and receive "content relevant" ads on their site from other site owners. Here is an example - those ads in the box on the right of the page are delivered by Google and are matched to the content
