window.scrollTo(0, 0);
var pdf = new jsPDF('p', 'pt', [1380, 2030]);
html2canvas($(".page-section")[0], {
onrendered: function(canvas) {
document.body.appendChild(canvas);
var ctx = canvas.getContext('2d');
var imgData = canvas.toDataURL("image/png", 1.0);
var width = canvas.width;
var height = canvas.clientHeight;
pdf.addImage(imgData, 'PNG', 20, 20, (width - 10), (height));
}
});
setTimeout(function() {
pdf.save('sample.pdf');
var blob = pdf.output("blob");
var blobURL = URL.createObjectURL(blob);
var iframe = document.getElementById('sample-pdf');
iframe.src = blobURL;

I started an ASPNET MVC project and I tried to load a gltf object
GLTFLoader.js -> https://github.com/mrdoob/three.js/blob/master/examples/js/loaders/GLTFLoader.js
But my object isn't found... chrome console :
Project files:
I added something in web config:
<script src="~/Scripts/three.js"></script>
<script src="~/Scripts/OrbitControls.js"></script>
<script src="~/Scripts/GLTFLoader.js"></script>
<script>
var app = new Vue({
el: '#app',
data: {
test: 'xd'
}
});
</script>
<script>
var scene, renderer, camera;
var cube;
var controls;
function initialize() {
scene = new THREE.Scene();
scene.background = new THREE.Color(0xdddddd);
camera = new THREE.PerspectiveCamera(45, window.innerWidth / window.innerHeight, 1, 10000);
camera.lookAt(new THREE.Vector3(0, 0, 0));
camera.rotation.y = 45 / 180 * Math.PI;
camera.position.set(800, 100, 1000);
ambientLight = new THREE.AmbientLight(0x404040, 100);
scene.add(ambientLight)
renderer = new THREE.WebGLRenderer({ antialias: true });
renderer.setSize(window.innerWidth, window.innerHeight);
$('#object').append(renderer.domElement);
let loader = new THREE.GLTFLoader();
loader.load('Cars/tutorial/scene.gltf', function (gltf) {
car = gltf.scene.children[0];
car.scale.set(0.5, 0.5, 0.5)
scene.add(gltf.scene);
renderer.render(scene, camera);
})
}
initialize();

I am using below javascript code to create blob URL. If video size is more like(500mb), then it is taking lot of time.
Please help me to create blob URL for large videos
if we can see Youtube the videos are playing very fast even though they are big in size with BLOB URL
<html>
<head>
<title>Blob URL</title>
</head>
<body>
<video controls="" preload="auto" id="_video"></video>
<script>
var xhr = new XMLHttpRequest();
xhr.responseType = 'blob';
xhr.onload = function() {
var reader = new FileReader();
reader.onloadend = function() {
//console.log(atob(reader.result.slice(reader.result.indexOf(',') + 1)));
var byteCharacters = atob(reader.result.slice(reader.result.indexOf(',') + 1));
var byteNumbers = new Array(byteCharacters.length);
for (var i = 0; i < byteCharacters.length; i++) {
byteNumbers[i] = byteCharacters.charCodeAt(i);
//console.log(i);
}
var byteArray = new Uint8Array(byteNumbers);
var blob = new Blob([byteArray], {type: 'video/mp4'});
var url = URL.createObjectURL(blob);
document.getElementById('_video').src = url;
}
reader.readAsDataURL(xhr.response);
};
xhr.open('GET', 'domain.com/738-360p.mp4',true);
xhr.send();

i want to add content after a table in a pdf file that was created with jsPDF autotable.
My Code:
$('#printBtn').on('click', function() {
var pdf = new jsPDF('p', 'pt', 'a4');
var res = pdf.autoTableHtmlToJson(document.getElementById("tablePrint"));
var anfang = "Anfang";
pdf.text(anfang, 14, 30);
pdf.autoTable(res.columns, res.data, {
theme : 'plain',
styles: {
fontSize: 12
},
showHeader: 'never',
createdCell: function(cell, data) {
var tdElement = cell.raw;
if (tdElement.classList.contains('hrow')) {
cell.styles.fontStyle = 'bold';
}
}
});
var ende = $('#ende_text').text();
pdf.text(ende, 0, 12);
pdf.save("test.pdf");
});
My Problem is that the code isn't formatted. The tags and everything else was ignored by jsPDF.
How can i fix that or what can i do that the text has line breaks and not overflow?
Thanks for help!
margins={
top=50,
left=30,
bottom=50,
width=520
}
var pdf = new jsPDF("p", "pt","a4");
var res = pdf.autoTableHtmlToJson(document.getElementById("table2"));
pdf.autoTable(res.columns, res.data,{
margin: { left: 30,bottom:100},
startY: 30, pageBreak: 'always',
styles: {overflow: 'linebreak', columnWidth: 'wrap', font: 'arial',
cellPadding: 8, overflowColumns: 'linebreak'}
});
pdf.fromHTML($("#editor1").get(0), 30, pdf.autoTableEndPosY() + 20, {
'width': margins.width
},function(dispose)
{
var iframe = document.createElement('iframe');
iframe.setAttribute('style','position:absolute;right:0; top:0; bottom:0; height:100%; width:40%; padding:20px;');
document.body.appendChild(iframe);
iframe.src = pdf.output('datauristring');
//pdf.save('name.pdf');
},
margins);
iam using the latest version of jspdf.min.js and jspdf.autotable.js

I tried to get a map image from a wms server using the following code.

ol3 fails to show the image, because the wms sends backs a xml exception report instead of jpeg data meaning
crs is not permitted: EPSG:3857.
On the java console we see the message
Resource interpreted as Image but transferred with MIME type text/xml ...
I understand, that the image source is not set up correctly. This needs further investigaton by me. But My question is:
How can I catch the message crs is not permitted: EPSG:3857 and any other error messages from the wms server by the ol script?
You will need to use XHR to load the image and get the exception text, see this thread for some inspiration:
https://groups.google.com/d/msg/ol3-dev/39tX1fSeSc0/KGURE6NrexIJ
imageLoadFunction: function(image, src) {
progress('start');
var img = image.getImage();
if (typeof window.btoa == 'function') {
var xhr = new XMLHttpRequest();
xhr.open('GET', src, true);
xhr.responseType = 'arraybuffer';
xhr.onload = function(e) {
if (this.status == 200) {
var uInt8Array = new Uint8Array(this.response);
var i = uInt8Array.length;
var binaryString = new Array(i);
while (i--) {
binaryString[i] = String.fromCharCode(uInt8Array[i]);
}
var data = binaryString.join('');
var type = xhr.getResponseHeader('content-type');
if (type.indexOf('image') === 0) {
img.src = 'data:' + type + ';base64,' + window.btoa(data);
} else {
error($.parseJSON(data));
}
} else {
error(this.statusText);
}
progress('end');
};
xhr.send();
} else {
img.onload = function() {
progress('end');
};
img.onerror = function() {
progress('end');
error();
};
img.src = src;
}
}
})
