how to fix the position of mask in snapsvg.js? - javascript

Here is js code:
var cv = Snap('#cv').attr({height: '100%', width: '100%'});
var mskHide = cv.rect().attr({height: '100%', width: '100%', left:0, top:0, fill: '#666'});
var mskShow = cv.circle(200, 200, 150).attr({fill: '#fff'});
var mskG = cv.group(mskHide, mskShow);
var bg = cv.circle(200, 200, 150).attr({fill: '#aaa'});
var customImg = cv.image('http://placehold.it/500/990000').attr({mask: mskG});
//when I drag the customImg, I want mskG fixed position
customImg.drag();
You can preview here: http://codepen.io/rlog/pen/eKBlc
The question is: When I drag the customImg, how can I fix the position of mskG.
The mskG is no need move whit costomImg
this example is what I want: http://codepen.io/rlog/pen/bAImu
Thanks!

You could basically do what you have in the 2nd codepen.
var cv = Snap('#cv').attr({height: '100%', width: '100%'});
var mskHide = cv.rect().attr({height: '100%', width: '100%', left:0, top:0, fill: '#666'});
var mskShow = cv.circle(200, 200, 150).attr({fill: '#fff'});
var mskG = cv.group(mskHide, mskShow);
var bg = cv.circle(200, 200, 150).attr({fill: '#aaa'});
var customImg = cv.image('http://placehold.it/500/990000').attr({mask: mskG });
customImg.drag( myDrag );
function myDrag(dx,dy,x,y) {
customImg.attr({ x: dx, y: dy })
}
codepen
If you want a different drag from the example shown to include stored start drag location, you would amend it something like the following...
customImg.attr({ x: 0, y: 0})
var move = function(dx,dy) {
this.attr({
x: +this.data('ox') + +dx,
y: +this.data('oy') + +dy
})
}
var start = function(x,y) {
this.data('ox', this.attr('x'));
this.data('oy', this.attr('y'));
}
var end = function(x,y) {}
customImg.drag( move, start, end )

What are getClientRect(); method and layer.children.each do in JavaScript?

How does the getClientRect(); method work in this code? Is that mean to get the sides of the rectangle?
Also, what is layer.children.each in the code below? Is that mean selecting each child of the node? Can anyone explain to me how these methods work? I checked the document but still not getting how they work.
Thank you so much for your help! I was able to solve this problem.
var stage = new Konva.Stage({
width: 400,
height: 200,
container: 'container'
});
var layer = new Konva.Layer();
stage.add(layer);
layer.on('dragmove', function(e) {
var target = e.target;
var targetRect = e.target.getClientRect();
layer.children.each(function(obj) {
if (obj === target) {
return;
}
if (haveIntersection(obj.getClientRect(), targetRect)) {
alert("Intersection")
}
});
});
function haveIntersection(r1, r2) {
return !(
r2.x > r1.x + r1.width/2 ||
r2.x + r2.width/2 < r1.x ||
r2.y > r1.y + r1.height/2 ||
r2.y + r2.height/2 < r1.y
);
}
// This will draw the image on the canvas.
function drawImage(source, konvaImage) {
layer.add(konvaImage);
var image = new Image();
image.src = source;
image.onload = function() {
konvaImage.image(image);
layer.draw();
}
}

A layer may have several children elements. So layer.children is just an array with of such objects.
layer.children.each(func) is a function similar to Array.prototype.forEach()
. It allows to to executre a function for every element in children array.
node.getClientRect() is a function that calcualte absolute boudning box of any Konva.Node. Bounding box is just an object like this:
{
x: 10,
y: 10,
width: 60,
height: 60
}
It allows you to detect the position and the size of any object, even if it is scaled, rotate, etc. Usually, that function can be used to defined position f edges of the shapes.

How to free draw circle using Fabric.js?

I am using FabricJS to draw circle in canvas:
var circle = new fabric.Circle({radius: 100,
fill: '',
stroke: 'red',
strokeWidth: 3,
originX: 'center',
originY: 'center'
});
var text = new fabric.Text('HELLO WORLD.',
{ fontSize: 30,
originX: 'center',
originY: 'center',
fill : 'red'
});
var group = new fabric.Group([ circle, text ], {
left: 150, top: 100
});
canvas.add(group);
This code draws a normal circle but I need to freely draw circle with mouse.
Any code help will be appreciated.
According to your previous code for drawing rectangle http://jsfiddle.net/Subhasish2015/8u1cqasa/2/ Here is the code for drawing circle:

Here is the detail blog with jsfiddle - https://blog.thirdrocktechkno.com/sketching-circle-of-a-html5-canvas-using-the-fabricjs-f7dbfa20cf2d
Here is an example of drawing a rectangle which I carefully made and works for latest versions. Krunan example seems to work OK- just in case this is a rectangle free drawing implementation that doesn't use DOM apis like e.clientX, offsetLeft, etc to track the coords, but fabric.js APIs only which I think is safer. Also unregister event listeners - I'm still trying to refine it since I need free drawing support for my project - Since there is no official support for this I wanted to reference the example here for others.

An easy way to add a Circle to a canvas:

Drag And Drop Image to Canvas (FabricJS)

The Problem
I want to do this with an image instead of a canvas object. Meaning you have to add the thing you want to add TO AND AS A PART of the canvas before you can add it. The images are actually part of the website so it doesn't need to do some intricate stuff. This code I found here only works for when it's an object not an actual element. And by the way I'm using FabricJS just to let you know that I'm not using the default HTML5 canvas stuff.
As for any alternatives that are possibly going to work without using my current code. Please do post it down below in the comments or in the answers. I would really love to see what you guys got in mind.
Summary
Basically I want to be able to drag and drop images through the canvas while retaining the mouse cursor position. For example if I drag and image and the cursor was at x: 50 y: 75 it would drop the image to that exact spot. Just like what the code I found does. But like the problem stated the CODE uses an object for you to drag it to the canvas then it clones it. I want this functionality using just plain old elements. E.g: <img>.

More codes that I found but doesn't answer my problem:
var canvas = new fabric.Canvas('c');
canvas.on("after:render", function(){canvas.calcOffset();});
var started = false;
var x = 0;
var y = 0;
var width = 0;
var height = 0;
canvas.on('mouse:down', function(options) {
//console.log(options.e.clientX, options.e.clientY);
x = options.e.clientX;
y = options.e.clientY;
canvas.on('mouse:up', function(options) {
width = options.e.clientX - x;
height = options.e.clientY - y;
var square = new fabric.Rect({
width: width,
height: height,
left: x + width/2 - canvas._offset.left,
top: y + height/2 - canvas._offset.top,
fill: 'red',
opacity: .2
});
canvas.add(square);
canvas.off('mouse:up');
$('#list').append('<p>Test</p>');
});
});
This code adds a rectangle to the canvas. But the problem is this doesn't achieve what I want which is basically, as previously stated, that I want to be able to drag an img element and then wherever you drag that image on the canvas it will drop it precisely at that location.

Fabric JS: Copy/paste object on mouse down
fabric.js Offset Solution
it doesn't need to do some intricate stuff.
A logical framework under which to implement image dragging might be to monitor mouse events using event listeners.
On mouse down over an Image element within the page but not over the canvas, record which image element and the mouse position within the image. On mouse up anywhere set this record back to null.
On mouse over of the canvas with a non empty image record, create a Fabric image element from the Image element (as per documentation), calculate where it goes from the recorded image position and current mouse position, paste it under the mouse, make it draggable and simulate the effect of a mouse click to continue dragging it.
I have taken this question to be about the design and feasibility stages of program development.

I have to draw a draggable textpath with kineticjs, with text given by an input text, the action is triggered in blur.
I have a stage that contain 3 layers;
Layer for the background, and one layer for the textpath.
My problem that the draggable in the textpath is not working,
i tried to set the text layer in the top, but i didn't get it draggable.
This is my jsfiddle
I have a doubt of inner layer problem.
Thanks in advance.

Delaying the Removal of Elements with Raphael.js

I'm trying to create a detailed animation using Raphael that has multiple scenes, but I've run into an issue; how can I delay the removal of elements if I want to move onto another scene? In my animation, the first "scene" is of four seals popping out of a body of water, after which I want them to be underwater, which would require the removal of unneeded elements from that scene. I'm not sure however how to remove those elements at the time that the first scene ends. The only way I can think of doing this at the moment is by cheating and animating them off the page. Also, is there a way to group elements together from the first scene and then remove that group instead of having to remove them all individually? Here's what I have so far:
window.onload = function (){
var paper = new Raphael( 0, 0, 800, 600);
var backGround = paper.rect(0,0,800,600).attr({ fill: "90-white:60-#9dc8f3", stroke : "none"});
var sun = paper.circle (400, 300, 60).attr({ fill: "90-orange-yellow", stroke : "none"})
var water1 = paper.rect(0,200,800,400).attr({ fill: "#2e659c", stroke : "none"});
var seal1 = paper.image("sealright.png", 190, 270, 140, 175);
var water2 = paper.rect(0,280,800,400).attr({ fill: "#2e659c", stroke : "none"});
var seal2 = paper.image("sealleft.png", 430, 350, 180, 225);

var water4 = paper.rect(0,440,800,400).attr({ fill: "#2e659c", stroke : "none"});
var seal4 = paper.image("shadeseal.png", 460, 510, 260, 327);
var water5 = paper.rect(0,520,800,400).attr({ fill: "#2e659c", stroke : "none"});

Could you just hide the element (otherwise you could use this same principle and make the function actually remove the element, the 4th animate element is a callback). So here is a combination that sequences a move after another move followed by a hide. Fiddle here http://jsfiddle.net/Lmbvm/3/
var paper = new Raphael(100,0,2000,2000);
var rect = paper.rect(50,50,50,50);
var rect2 = paper.rect(100,100,100,100);
var set = paper.set();
set.push( rect, rect2 );
var animation = Raphael.animation({ x: 200 },200,"linear", animateCircle);
set.animate( animation );
var circle = paper.circle(50,50,50);
function animateCircle() {
circle.animate({ cx : 200 }, 200, "linear", hideCircle);
};
function hideCircle() {
set.hide();
}
Edit: I've updated a fiddle here http://jsfiddle.net/Lmbvm/8/ to move a set as well
