i make a map with this code
var map;
var myOptions = {
center: new google.maps.LatLng(-31.403759,-64.174232),
zoom: 12,
panControl: true,
zoomControl: true,

mapTypeId: google.maps.MapTypeId.ROADMAP
};
function iniciar() {
map = new google.maps.Map(document.getElementById("map"),myOptions);
}
function marcar(lat, lng) {
var contentString = '<div id="content">'+
'<div id="siteNotice">'+
'</div>'+
'<h1 id="firstHeading" class="firstHeading">Uluru</h1>'+
'<div id="bodyContent">'+
'<p><b>Uluru</b>, also referred to as <b>Ayers Rock</b>, is a large ' +

var infowindow = new google.maps.InfoWindow({
content: contentString
});
var location=new google.maps.LatLng(lat,lng);
var marker = new google.maps.Marker({
position: location,
map: maps
});
google.maps.event.addListener(marker, 'click', function() {
infowindow.open(map,marker);
});
}
When I try to click on markers, they are decalibrated so that when I click on the center of a marker nothing happens. But a few centimeters down, a cursor appears like the marker is at that point.
So the map is not centered and the marker appears at the real coordinates, but I have to click 2 cm down away from the marker for the click on the marker...
Why is that?? Has anybody else had this happen??
the problem was the body... in my css i put
body{
zoom:0.9;
margin:0;
padding:0;
width:100%;
}
the zoom affects the google maps remove the zoom calibrate the marker.... thank you all!! i hope this problem solve any other similar problems
and sry for my bad english! ejejej

Here is my code.
import { fabric } from "fabric";
const canvas = new fabric.Canvas("c", { isDrawingMode: true });
canvas.setBackgroundColor("rgb(255,73,64)", canvas.renderAll.bind(canvas));
canvas.on("path:created", e => {
let mousePath = e.path;
let offsetPath = new fabric.Path();
let offsetLeft = mousePath.left + 60;
let offsetTop = mousePath.top + 60;
offsetPath.setOptions({
path: mousePath.path,
left: offsetLeft,
top: offsetTop,
width: mousePath.width,
height: mousePath.height,
fill: '',
stroke: 'black'
});
canvas.add(offsetPath);
canvas.requestRenderAll();
});
Here is an resulting image of my drawing session.
I drew the happy face in the top left corner of the canvas with my mouse.
The offset image was added by my code.
How can I change my code to make the offset drawing look like the one drawn with my mouse?
Edit: from https://github.com/fabricjs/fabric.js/wiki/When-to-call-setCoords
I tried using
offsetDraw.setCoords();
but I was unable to find a way to make it work.
Edit: What I have presented here is a minimized example. I am working on an larger project where I save each path drawn by the user. Later I recreate those paths in an animation like sequence.
Edit: I made some changes to my code in a effort to understand fabricjs.
const canvas = new fabric.Canvas("c", { isDrawingMode: true });
canvas.setBackgroundColor("rgb(255,73,64)", canvas.renderAll.bind(canvas));
canvas.on("path:created", e => {
let mousePath = e.path;
let offsetPath = new fabric.Path();
let offsetLeft = mousePath.left + 60;
let offsetTop = mousePath.top + 60;
offsetPath.setOptions({
path: mousePath.path,
//left: offsetLeft,
//top: offsetTop,
width: mousePath.width,
height: mousePath.height,
fill: '',
stroke: 'black'
});
canvas.add(offsetPath);
canvas.requestRenderAll();
console.log("mousePath left " + mousePath.left + " top " + mousePath.top);
console.log("offsetPath left " + offsetPath.left + " top " + offsetPath.top);
});
In that code, I commented out the setting of the left and top properties of the offsetPath and added console.log lines. I drew a circle in the top left corner of the canvas with my mouse. The resulting image was the following.
The following was printed in the console.
mousePath left 7.488148148148148 top 10.5
offsetPath left -0.5 top -0.5
I don't understand the results. Why was the offset circle rendered in that position?
Edit: I drew another test with my mouse.
It seems that the code repeats the paths of concentric circles rather well. But, the vertical lines are moved out of their correct position. Their displacements increase as the distance from the center increases. Why?
I found a solution for my own question. But, if someone has a better one, then please post it. Look at
https://stackblitz.com/edit/js-ncxvpg
The following is the code.
const canvas = new fabric.Canvas("c", { isDrawingMode: true });
canvas.setBackgroundColor("rgb(255,73,64)", canvas.renderAll.bind(canvas));
canvas.on("path:created", e => {
let mousePath = e.path;
mousePath.clone(clone => {
clone.setOptions({
left: mousePath.left + 100,
top: mousePath.top + 100
});
canvas.add(clone);
});
});
If someone has an explaination as to why my original code didn't work, then please post it.
thanks for sharing your comments on my question. I am facing a similar issue, just that if I click anywhere on the Canvas the first time. Then the offset issue vanishes. This happens for any object that I programmatically insert into the canvas.
In my case, I suspect that the canvas.pointer is having some offset of the current mouse position. However, when I click and add one very small path of 1pixel, then the pointer offset gets corrected. After this, all subsequent paths or objects created programatically are shown at the correct positions.
2.0 and I would like to see only one slide which is the class: "owl-item active center"
Could you help me?
thank you and have a good day
jQuery script :
var owl = $('.owl-carousel');
$(".owl-carousel").each(function(index, el) {
var containerHeight = $(el).height();
$(el).find("img").each(function (index, img) {
var w = $(img).prop('naturalWidth');
var h = $(img).prop('naturalHeight');
$(img).css({
'width': Math.round(containerHeight * w / h) + 'px',
'height': containerHeight + 'px'
});
})
});

I am working on an editor that will allow the user to create textboxes images and rectangles dynamically and that portion of the project works great. All objects on the canvas will pre-existing before creating groups therefore I do not want to hard-code any fabrics. I also want to preserve the positional relation between the grouped items.
I am having a problem with creating groups by selecting 2 or more existing objects on the canvas to create a group. My code works with one exception, if the selected items are not in the upper left corner of the canvas when I create the group the grouped objects remain in the original location as desired but the move handle is in the upper left corner of the canvas. If you click the move cursor handle ghost and then click a blank area on the canvas the problem goes away and everything works fine after that.
I have had no luck searching for a solution possibly because I'm not sure what controls the move cursor's location on the canvas or if it is actually called the "move cursor".
Here is a picture from my jsfiddle after clicking the group button:
Here is a jsfiddle link to demonstrate the problem: https://jsfiddle.net/Larry_Robertson/xfrd278a/
Here is my code:
HTML
<span> Test 1: select both the line and the text objects with the mouse then click group, works great.</span>
<br/>
<span> Test 2: select both the line and the text objects with the mouse, move the selction to the center of the canvas then click group. This creates the problem where a ghost move handle is left behind in the upper left corner of the canvas. The move handle did not update to the correct position when the group was created. If you hover the mouse in the upper left of canvas you will see the move cursor. Click on the move cursor then click any blank part of the canvas then you can reselect the group and it moves properly. What am I doing wrong???</span>

<button id="group">group</button>
<canvas id="c" height="300" width="500"></canvas>
JS
var canvas = new fabric.Canvas('c');
var text = new fabric.Text('hello world', {
fontSize: 30,
originX: 'left',
originY: 'top',
left: 0,
top: 0
});
var line = new fabric.Line([10, 10, 100, 100], {
stroke: 'green',
strokeWidth: 2
});
canvas.add(line);
canvas.add(text);
canvas.renderAll();
$('#group').on(("click"), function(el) {
var activeObject = canvas.getActiveObject();
var selectionTop = activeObject.get('top');
var selectionLeft = activeObject.get('left');
var selectionHeight = activeObject.get('height');
var selectionWidth = activeObject.get('width');
if (activeObject.type === 'activeSelection') {
var group = new fabric.Group([activeObject], {
left: 0,
top: 0,
originX: 'center',
originY: 'center'
});
canvas.add(group);
deleteSelectedObjectsFromCanvas();
canvas.setActiveObject(group);
group = canvas.getActiveObject();
group.set('top', selectionTop + (selectionHeight / 2));
group.set('left', selectionLeft + (selectionWidth / 2));
group.set('originX', 'center');
group.set('originY', 'center');
canvas.renderAll();
}
});
function deleteSelectedObjectsFromCanvas() {
var selection = canvas.getActiveObject();
var editModeDected = false;
if (selection.type === 'activeSelection') {
selection.forEachObject(function(element) {
console.log(element);
if (element.type == 'textbox') {
if (element.isEditing == true) {
//alert('At least one textbox is currently being edited. No objects were deleted');
editModeDected = true;
}
}
});
if (editModeDected == true) {
return false;
}
// Its okay to delete all selected objects
selection.forEachObject(function(element) {
console.log('removing: ' + element.type);
//element.set('originX',null);
//element.set('originY',null);
canvas.remove(element);
canvas.discardActiveObject();
canvas.requestRenderAll();
});
} else {
if (selection.isEditing == true && selection.type == 'textbox') {
//alert('Textbox is currently being edited. No objects were deleted');
} else {
canvas.remove(selection);
canvas.discardActiveObject();
canvas.requestRenderAll();
}
}
}
CSS
#c {
margin: 10px;
padding: 10px;
border: 1px solid black;
}
After making changes on code always do a setCoords on the object(s) that got changed.
Here is a one liner you can add after the renderAll to fix your issue:
...
group.set('originY', 'center');
canvas.renderAll();
canvas.forEachObject(function(o) {o.setCoords()});
I'm importing several svgs that are all created from the same image and layered on top of each other. I would like to add text centered over a certain svg/textarea path. And then scale textarea to fit the text provided with a min size. And ive confused myself. I have no idea anymore? I deleted everything and started over direction would be very helpful. Heres what i got.
var canvas = new fabric.Canvas('canvas');
fabric.loadSVGFromURL('/1-man.svg', function(objects, options) {
var obj = fabric.util.groupSVGElements(objects, options);
canvas.add(obj).renderAll();
});
fabric.loadSVGFromURL('/1-man-cutout.svg', function(objects, options)
{
var obj = fabric.util.groupSVGElements(objects, options);
canvas.add(obj).renderAll();
});
fabric.loadSVGFromURL('/textarea.svg', function(objects, options) {
var obj2 = fabric.util.groupSVGElements(objects, options);
canvas.add(obj2).renderAll();
});
var text = new fabric.Text("Hello", {
fontFamily: 'ubuntu',
fontSize: 300,
textAlign: "center",
});
canvas.add(text);
Brain was dead i suppose.... took about a min this morning.. Ill keep it for a lesson on sleeping on it.
text.set('left', (objects[0].width - text.width)/2);
text.set('top', objects[0].top + 5);
canvas.add(obj2, text).renderAll();
How to keep all the qtips inside a container (I have already tried position.container, position.viewport and position.adjust.method) without any luck, my best guess is that I am not using them correctly.
Update:1 I have created a sample app with more details on below url
http://secure.chiwater.com/CodeSample/Home/Qtip
Update:2 I have created jsfiddle link too. http://jsfiddle.net/Lde45mmv/2/
Please refer below screen shot for layout details.
I am calling the area shown between two lines as $container in my js code.
So far I have tried tweaking viewport, adjust method but nothing helped. I am hoping this is possible and I would greatly appreciate any help.
Below is my javascript code which creates qtip2.
//Now create tooltip for each of this Comment number
$('#cn_' + num).qtip({
id: contentElementID,
content: {
text: .....
var $control = $('<div class="qtip-parent">' +
' <div class="qtip-comment-contents">......</div>' +
' <div class="clearfix"></div>' +
' <div class="qtip-footer"><span class="qtip-commenter">...</span><span class="pull-right">...</span></div>' +
'</div>'
);
return $control;
},
button: false
},
show: 'click',
hide: {
fixed: true,
event: 'unfocus'
},
position: {
my: 'top right',
at: 'bottom right',
target: $('#cn_' + num),
container: $container,
//viewport: true,
adjust: { method: 'shift none' }
},
style: {
tip: {
corner: true,
mimic: 'center',
width: 12,
height: 12,
border: true, // Detect border from tooltip style
//offset: 25
},
classes: 'qtip-comment'
},
events: {
show: function (event, api) {
...
},
hide: function (event, api) {
...
}
}
});
Example of jalopnik page which shows what I am looking for (FWIW jalopnik example doesn't use qtip2).
I don't think qtip API supports this functionality. I ended up re-positioning the tooltip on visible event.
I have updated the demo page and jsfiddle link below is code for doing this.
events: {
visible: function (event, api) {
var $qtipControl = $(event.target);
$qtipControl.css({ 'left': contentPosition.left + "px" });
var $qtipTipControl = $qtipControl.find(".qtip-tip");
var $target = api.get("position.target");
$qtipTipControl.css({ "right": 'auto' });
//I am using jquery.ui position
$qtipTipControl.position({
my: "center top",
at: "center bottom",
of: $target
});
}
}
Problem with this approach is that there is noticeable jump when I re-position the qTip. But in lack of any other option for time being I will settle with this.
The ideal approach would be to allow callback method thru position.adjust currently it only supports static values for x and y, if a method was allowed here it would make things much smoother.
