jspdf

I am trying to convert HTML5 canvas to PDF in JavaScript but I get a black background PDF. I tried to change the background color but still get black. The following is code I am trying: Canvas = document.getElementById("chart"); Context = Canvas.getContext("2d"); var imgData = Canvas.toDataURL('image/jpeg'); var pdf = new jsPDF('landscape'); pdf.addImage(imgData, 'JPEG', 0, 0, 1350, 750); pdf.save('download.pdf'); If you have any idea, I'd appreciate it very much. A good approach is to use combination of jspdf.js and html2canvas. I have made a jsfiddle for you. <canvas id="canvas" width="480"

I'm trying to create a simple pdf doc using javascript. I found jsPDF but I don't figure out how to center text. Is it possible? Tsilis Yes it's possible. You could write a jsPDF plugin method to use. One quick example is this: (function(API){ API.myText = function(txt, options, x, y) { options = options ||{}; /* Use the options align property to specify desired text alignment * Param x will be ignored if desired text alignment is 'center'. * Usage of options can easily extend the function to apply different text * styles and sizes */ if( options.align == "center" ){ // Get current font size

I need to send a png file to the backend server. I converted it to pdf using jsPDF: var doc = new jsPDF('l', 'mm', [210, 210]); doc.addImage(myPngData, 'PNG', 0, 0, 210, 210); Now I need to send it to the server using my old-school JQuery project: $.post(url, { key1: val1, key2: val2, pdf: //pdf file goes here, will doc work?, }, But what should I really send? Cause sending doc just won't work? Unfortunately I cannot just send and check it as the backend is not ready yet. You can use doc.output('datauristring') and send it to your server. Below is my code to send the whole html page to the

I have been using JSPDF to generate pdf document based on some html. Earlier using jspdf fromHTML Api, we could give margins like this var margins2 = { top: 415, bottom: 10, left: 55, width: 300 }; doc.fromHTML(reactListContent, margins2.left, margins2.top, { 'width': margins2.width, 'elementHandlers': specialElementHandlers }, margins2); But, in the new .html API , how can i provide margins, width and height. The new API is like var pdf = new jsPDF('p', 'pt', 'letter'); pdf.html(document.getElementById('html'), { callback: function (pdf) { console.log("how to get margins"); } }); If you look

I'm using jspdf.js to create pdf from HTML 5 canvas. However, regardless of what the contents are and how big the canvas size is, the generated file size is always 32,874 KB, even when the canvas is completey empty. Why the file size is always the same? jsPDF version is 1.1.135. My code is like this: var imgData = canvas.toDataURL("image/jpeg", 1.0); var width = $("canvas").attr('width'); var height = $("canvas").attr('height'); var pdf = new jsPDF('p', 'pt', [width,height]); pdf.addImage(imgData, 'JPEG', 0, 0, width, height); pdf.save("download.pdf"); UPDATE: Full code: $scope.rasterizePDF =

How can I manage to get special characters in a PDF file generated with jsPDF? The texts are dynamically loaded through AJAX. Some possible chars are à , É , Ç and õ . I, up to now, didn't get how to do this. Cesar You must download the last version of jsPDF, there will be a file called jspdf.plugin.standard_fonts_metrics.js, just reference that script from your html page and that would be more than enough to user special caracters would be a simple line like this: <script src="jspdf.plugin.standard_fonts_metrics.js"></script> <script> doc.text(74, 25, 'Evaluación de prueba'); </script> This

I am using jsPDF to generate PDF documents through Appcelerator's Titanium. Now i need to add a simple pie chart with two segments. How could i do that in simplest way? It doesn't need to be anything fancy. I am thinking about generating an image first, and add that image to the document. Maybe there's a library that could generate images of pie-chart's and save it to the phone. However, im not sure about jsPDF's support of images, i can't seem to find any good documentation of the library. arsenalist I know it has been inactive for almost a year, but since it doesn't have an accepted answer,
