Do you have any idea how to move the marker with the coordinates or URL? now when I click on 'Google' down on the map Photo the marker disappears.
I have an example here:
var map;
function initialize() {
var myLatlng = new google.maps.LatLng(48.8164526,-4.140963);
var mapOptions = {
zoom: 15,
center: myLatlng
};
map = new google.maps.Map(document.getElementById('map-canvas'),
mapOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title: 'Compacc Complete Accountancy'
});
}
google.maps.event.addDomListener(window, 'load', initialize);
html, body, #map-canvas {
height: 100%;
margin: 0;
padding: 0;
}
<div id="map-canvas"></div>
<script src="https://maps.googleapis.com/maps/api/js?v=3.exp&sensor=false" type="text/javascript"></script>
`
How can I show the marker on "The original Google map"?
I’ve created a graph with echarts and want to include it to a pdf by using jspdf. I found that one way to do so might be to use canvas, transfer the graph to an image and finally include the image to the pdf. However, I fail to transfer the graph to an image. Here comes the code:
<!DOCTYPE html>

<!-- prepare a DOM container with width and height -->
<div id="main" style="width: 750px; height: 500px"></div>
<script type="text/javascript">
// based on prepared DOM, initialize echarts instance
var myChart = echarts.init(document.getElementById('main'));
// specify chart configuration item and data
var option = {

barWidth: '60%',
data: [10, 52, 200, 334, 390, 330, 220]
}
]
};
// use configuration item and data specified to show chart
myChart.setOption(option);
var canvas = document.getElementById('main');
var dataURL = canvas.toDataURL();
//console.log(dataURL);
$('#exportButton').click(function () {
var pdf = new jsPDF();
pdf.addImage(dataURL, 'JPEG', 0, 0);
pdf.save('download.pdf');
});
</script>
<button id="exportButton" type="button">Export as PDF</button>
</body>
</html>
Any suggestions?
I needed this as well for a commercial product, so I did not give up until I found the solution.
You cannot use the ID of the chart to get the URL for the image, instead you need to search for the canvas.
($('canvas')[0]).toDataURL("image/png");
Notice the "[0]" means it will give your the first canvas, if you have more charts just do:
($('canvas')[0]).toDataURL("image/png");
($('canvas')[1]).toDataURL("image/png");
($('canvas')[2]).toDataURL("image/png");
3 Hours of searching and testing well spent :)
Enjoy!
I would use the toolbox, save as image:
.....
toolbox: {
feature: {
saveAsImage : {show: true}
}
}
.....
This option, among all the existing ones, will show you an icon to save the graphic as an image.
Quedaria así:
enter image description here
For more options with toolbox: http://echarts.baidu.com/echarts2/doc/option-en.html#title~toolbox
I hope it helps you.
You have to import "html2canvas" in order to make this work.
Html2canvas library will get the snapshot and that image should be written to the pdf with jspdf.
I have created a pen for this.
$("#exportButton").click(function(){
html2canvas($("#main"), {
onrendered: function(canvas) {
var dataURL=canvas.toDataURL('image/jpeg');
var pdf = new jsPDF();
pdf.addImage(dataURL, 'JPEG', 0, 0);
pdf.save("download.pdf");
}
});
});
Echart code:
<ReactEcharts
ref={(e) => {
this.echarts_react = e;
}}
option={option}
notMerge
lazyUpdate
/>
Function:
saveAsImage = (uri, name = 'undefine.jpeg') => {
var link = document.createElement('a');
link.download = name;
link.href = uri;
document.body.appendChild(link);
link.click();
};
saveAsPDF = (uri, name = 'undefine.pdf') => {
let height = echartsInstance.getHeight();
let width = echartsInstance.getWidth();
var doc = '';
if (width > height) {
doc = new jsPDF('l', 'mm', [width, height]);
} else {
doc = new jsPDF('p', 'mm', [height, width]);
}
doc.addImage(echartsInstance.getDataURL({ backgroundColor: '#fff' }), 'JPEG', 10, 10);
doc.save(name);
};
function call:
<li className="nav-item inline dropdown">
<span className="nav-link" data-toggle="dropdown">
<i className="fa fa-download" />
</span>
<div className="dropdown-menu dropdown-menu-scale pull-right">

this.saveAsImage(this.echarts_react.getEchartsInstance().getDataURL({ backgroundColor: '#fff' }))

I have a image like this
var image = new Kinetic.Image({
x : x,
y : y,
width : 1000,
height :100,
image : image,
});
How do I get the mouse position based on the image.
according this example, I could get position Object{0, 0} ~ {100, 1000}
I only found an api stage.getPointerPosition()
If you want to get mouse position on click then you can do this:
image.on('click', function(){
var mousePos = youStage.getPointerPosition();
var p = { x: mousePos.x, y: mousePos.y }; // p is a clone of mousePos
var r = image.getAbsoluteTransform().copy().invert().point(mousePos);
});
Please find the working example below albeit it uses KonvaJS but the concept is same. And you should also start using Konva cause it's well maintained and documented.

Can you please take a look at this JSFiddle and let me know why I am not able to add the Market into the Map? I am getting this error

You are trying to add this point when the map isn't fully loaded.
So just wait for the map to be fully loaded and then add the point, by wrapping your loop inside this function:
map.on('load', function() {
console.log('load event called');
for (i = 0; i < graphicsArray.length; ++i) {
map.graphics.add(graphicsArray[i]);
}
});
ESRI has a small documentation on how to work with events here
Can someone tell me why I can't see the marker on this map?

Look in your browser's error console:
Uncaught ReferenceError: map is not defined
You need to expose that variable, since map is not currently visible outside of the scope of initialize(). Or, move the marker code into initialize():
function initialize() {
var mapOptions = {
center: new google.maps.LatLng(37.998727,-0.686259),
