I cannot scale the image when moving the scale controller. It shows the following error:
Uncaught TypeError: canvas.requestRenderAll is not a function
Can please anyone help to solve this problem? I want the functionality to be implemented for image please refer to this. Here is my code:

Here is the result. You need to change the scale of the object on onchange event callback.

I have a paper-dialog in my Polymer element. I want to make the backdrop opaque, right now it is semi-transparent. I would also like to change the color.
Does anyone know how to do it. I have already tried this css in my custom element:
<style is="custom-style">
--iron-overlay-backdrop-opacity:1;
</style>
<paper-dialog modal></paper-dialog>
But it had no effect.
I also tried
<style is="custom-style">
:host {
--iron-overlay-backdrop-opacity:1;
}
</style>
<paper-dialog modal></paper-dialog>
The iron-overlay-backdrop is appended directly to the document body, outside of your custom element, and due to Polymer's CSS encapsulation, you can't style the backdrop with a <style> from within the element.
However, your element could imperatively style the backdrop with Polymer.updateStyles(...), which updates the styles for all custom elements, including the iron-overlay-backdrop outside your element:
Polymer.updateStyles({
'--iron-overlay-backdrop-background-color': 'red',
'--iron-overlay-backdrop-opacity': '1'
});

Or to set a fixed static style for all backdrops, use <style is="custom-style"> from the body:
<body>
<style is="custom-style">
iron-overlay-backdrop {
--iron-overlay-backdrop-opacity: 1;
--iron-overlay-backdrop-background-color: green;
}
</style>
<x-dialog></x-dialog>

});
$('.button_click_2').click(function () {
console.log('btn 2 clicked');
});
});
</script>
Thank you .
Import the Font in pdfMake.
Afterwards update the vfs_fonts.js as described on github
assign pdfMake.fonts in your javascript
$(document).ready(function () {
pdfMake.fonts = {
'SolaimanLipi': {
normal: 'SolaimanLipi-Regular.ttf',
bold: 'SolaimanLipi-Medium.ttf'
}
};
var docDefinition = {
content: 'হ্যালো',
defaultStyle:{
font: 'SolaimanLipi'
}
};
$('.buttin_click_1').click(function () {
console.log('btn 1 clicked');
pdfMake.createPdf(docDefinition).open();
});
$('.button_click_2').click(function () {
console.log('btn 2 clicked');
});
});
This is what I have tried:

Here's the live demo: https://jsbin.com/giqufilusu/1/edit?html,output
I don't know why its not working. Is there a syntax problem or I didn't code the correct way. There are some examples on web but most of them use jquery + raphael js to draw line on mouse events but I want to draw with drag() method of raphael. How do I fix this?
I don't know if I got you right.
I guess this is what you want to achieve?
You defined the line variable only in the scope of the start function. To adapt the line you need to make it available to all functions. The jsBin is a quick and dirty approach which should give you a hint how you can do this line drawing with Raphael.
Whenever i try to load the google maps html code i never get anything to display and i get the following error:
ReferenceError: google is not defined
I can create a hyperlink to google maps but this isn't what i want. I also went ahead and got my own API key and put it into my code. Why isn't google defined? This seems too common of a problem to not have a solution.
Here is my HTML:
<!DOCTYPE html>
<html>
<head>
<title>My first Google Map</title>
<meta name="viewport" content="initial-scale=1.0, user-scalable=no" />
<style type="text/css">
html {
height: 100%;
}
body {
height: 100%;
margin: 0;
padding: 0;
}
#map-canvas {
height: 100%;
}
</style>
<script type="text/javascript"
src="https://maps.googleapis.com/maps/api/js?key=AIzaSyDX71YSt1efYJH3MdIsH3SF3kyJNjN-Z78&sensor=false">
</script>
<script type="text/javascript">
function initialize() {
var myLatLng = new google.maps.LatLng(54.124634, -3.237029)
var mapOptions = {
center: myLatLng,
zoom: 17,
mapTypeId: google.maps.MapTypeId.SATELLITE
};
var map = new google.maps.Map(document.getElementById("map-canvas"),
mapOptions);
var myMarker = new google.maps.Marker({
position: myLatLng,
map: map,
title: "A place on Earth",
draggable: true,
})
}
google.maps.event.addDomListener(window, 'load', initialize);
</script>
</head>
<body>
<div id="map-canvas" />
</body>
</html>
I feel strange that I cannot find the actual dragging-handling code in Fabric.js's demo (for example, this one), but the objects are already draggable "automatically", which is not my case. Here's my code in an external test.js file:
$(function(){
var canvas = new fabric.Canvas('c');
canvas.setWidth(window.innerWidth);
canvas.setHeight(window.innerHeight);
fabric.Image.fromURL('1.png', function(img) {
var group = new fabric.Group([img],
{
hasBorders: false,
hasControls: false,
selectable: true,
evented: true
})
canvas.add(group).setActiveObject(group);
},
{
originX: 'left',
originY: 'top'
});
canvas.renderAll();
});
And here is the test.html:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8" />
<title>test</title>
<script type="text/javascript" src="http://code.jquery.com/jquery-2.0.3.min.js"></script>
<script type="text/javascript" src="http://cdnjs.cloudflare.com/ajax/libs/fabric.js/1.3.0/fabric.min.js"></script>
<script type="text/javascript" src="test.js"></script>
</head>
<body>
<canvas id="c"></canvas>
</body>
</html>
Am I missing something? Thank you.
UPDATE: solved by using the newest fabricjs (1.3.12) in github.
