how to make image background of text in phaser js? - phaser-framework

my Image is the and code is here i want to make nameplate of text. This is scorolble panel.
const updatePanel = (panel, content) => {
const sizer = panel.getElement("panel");
const { scene } = panel;
var nameImage, nameText;
sizer.clear(true);
const lines = content.split("\n");
for (let li = 0, lcnt = lines.length; li < lcnt; li += 1) {
const words = lines[li].split(" ");
for (let wi = 0, wcnt = words.length; wi < wcnt; wi += 1) {
nameText = sizer.add(
scene.add
.text(0, 0, words[wi], {
fontSize: 20,
fill: "#f4b331",
})
.setInteractive()
.on("pointerdown", () => {
// this.scene.print.text = this.text;
// this.setTint(Phaser.Math.Between(0, 0xf4b331));
})
);
console.log("new line")
}
if (words != '' && content != "Loading...") {
nameImage = sizer.add(scene.add.sprite(0, 0, "nameplate"));
}
if (li < lcnt - 1) {
sizer.addNewLine();
}

How to rotate sprite image in 360 degree view in fabric js

But the problem is iam not able to rotate the sprite image based on user interaction.for eg: when the user moves the mouse on right the frame on right side should moved and when the user moves on left the left side of the frames should me moved iam not able to implement this in fabric js. What i have done is just rotating the sprite image onmouse move.Expected output i want is like this :https://codyhouse.co/demo/360-degrees-product-viewer/index.html
var URL = 'https://codyhouse.co/demo/360-degrees-product-viewer/img/alfa.png';
var canvas = new fabric.Canvas('canvas');
var positions = {
topSteps: 1,
leftSteps: 16
};
var y = 0;
var x = 0;
var topStep;
var leftStep;
canWalk(URL, positions);
function canWalk(URL, positions) {
var myImage = new Image();
myImage.src = URL;
//var mDown = false;
//onloadevent
myImage.onload = function () {
topStep = myImage.naturalHeight / positions.topSteps;
leftStep = myImage.naturalWidth / positions.leftSteps;
var docCanvas = document.getElementById('canvas');
docCanvas.height = topStep;
docCanvas.width = leftStep;
fabricImageFromURL(x, y);
};
}
//mouseevents
canvas.on('mouse:out', function (event) {
console.log("mouseout")
/* x=0;
y=0;
fabricImageFromURL(x,y);*/

As we are not changing top value, no need to set top value all the time, just set left value for the image. pixelToSkip is the difference between mousemove pixel to call the function, if mouse move difference is less than that , then it wont call.

leftSteps: 16
};
var y = 0;
var x = 0;
var topStep;
var leftStep;
var isMouseDown = false;
var imgObject, pixelToSkip = 10;
var clickedPointer, currPointer, diff;
canWalk(URL, positions);
function canWalk(URL, positions) {
var myImage = new Image();
myImage.src = URL;
//var mDown = false;
//onloadevent
myImage.onload = function() {
topStep = myImage.naturalHeight / positions.topSteps;
leftStep = myImage.naturalWidth / positions.leftSteps;
canvas.setDimensions({
height : topStep,

})
fabricImageFromURL(x, y);
};

});
canvas.on('mouse:move', function(event) {
if (!isMouseDown) return;
currPointer = canvas.getPointer(event.e);
diff = currPointer.x - prevPointer.x;

Fabricjs text spacing

I have override fabricjs Text object to make letter spacing
fabric.util.object.extend(fabric.Text.prototype, {
letterSpace: 0,
_renderChars: function(method, ctx, chars, left, top) {
if(!this.letterSpace){
ctx[method](chars, left, top);
return;
}
var charShift = 0;
for(var i = 0; i < chars.length; i++){
if(i > 0){
charShift += this.letterSpace + ctx.measureText(chars.charAt(i-1)).width;
}
ctx[method](chars.charAt(i), left+charShift, top);
}
},
_getLineWidth: function(ctx, lineIndex) {
if (this.__lineWidths[lineIndex]) {
return this.__lineWidths[lineIndex];
}
var lineLength = this._textLines[lineIndex].length;
var additionalSpaceSum = 0
if(lineLength > 0){
additionalSpaceSum = this.letterSpace * (lineLength - 1);
}
this.__lineWidths[lineIndex] = ctx.measureText(this._textLines[lineIndex]).width + additionalSpaceSum;
return this.__lineWidths[lineIndex];
}
});
Spacing works good, but width is not correct, how to improve width calculation?
I have improve my code in this question and now it work fine))
Sorry for not show previous mistake, but here is too difficult to make clear cod, and I have correct previous in this question.
But I have write it for left text align, if you use different align you need correct it. For me it was enough

}
}else if(this.textAlign == 'center'){
var totalWidth = 0;
for (var i = 0; i < characters.length; i++) {
totalWidth += (ctx.measureText(characters[i]).width + this.letterSpace);
}
var currentPosition = left - (totalWidth / 2);
var charShift = 0;
for (var i = 0; i < chars.length; i++) {
if (i > 0) {
charShift += this.letterSpace + ctx.measureText(chars.charAt(i - 1)).width;
}
ctx[method](chars.charAt(i), currentPosition + left + charShift, top);
}
}
},
_getLineWidth: function (ctx, lineIndex) {
var lineLength = this._textLines[lineIndex].length;
var additionalSpaceSum = 0
if (lineLength > 0) {
additionalSpaceSum = this.letterSpace * (lineLength - 1);
}

Here is an example: http://jsfiddle.net/peybdq94/
I tried implementing this feature and came up with this https://jsfiddle.net/ghazaltaimur/bx0f4qpg/1/ by extending _renderChar. I have made a couple of additions. The code allows letter spacing to be applied on the selected text instead of only on the whole object.Plus itext selection ,bounding box and cursor position have to be taken into account if letter spacing is to be added. I have tried to cover these aspects as well. There might be a couple of issues which still need to be fixed.

socket.io.js path in nodejs with localhost in windows

I have installed node.js v0.10.31 and npm v1.4.3 and also installed node-uuid, socket.io and express
I am trying to create a simple chat app, but the socket.io path i referred was so confusing. my installed socket.io path is D:\program files\nodejs\node_modules\socket.io my project files in the localhost in xampp (for php)
referred from tutorials link /socket.io/socket.io.js but my link in
D:\program files\nodejs\node_modules\socket.io\node_modules\socket.io-client\socket.io.js
how can i use to include <script src="/socket.io/socket.io.js"></script> to ??
i have two files in my projectand i copied node_modules folder to project folder from nodejs

Getting error:
GET http://localhost:3000/socket.io/?EIO=3&transport=polling&t=1423454007198-4 net::ERR_CONNECTION_REFUSED
If you set up socket.io properly with your http server (you don't show us that part of your code), then it automatically handles the request for "/socket.io/socket.io.js" and serves up the socket.io.js file to the client that actually resides elsewhere. In other words, it handles it all for you by intercepting the http request for "/socket.io/socket.io.js" and serving up the desired file from it's location in the node_modules directory that the socket.io server code came from.

I am trying to export rallygrid data in excel file, but getting only headers not values

I am trying to export rallygrid data in excel file, but getting only headers not values.
Below is my code which I wrote to generate grid and export button
From here [https://github.com/andreano/TaskDelta/blob/master/App.js], I stole the export code

There is an example in new AppSDK2 documentation of exporting to CSV.
I also have an example of exporting to CSV in this github repo.
