Arrange Raphael Objects in Their Relative Positions

I've been experimenting with Raphael.js recently and I've encountered an issue related to the positioning of each Raphael object.

My goal is to create multiple 'canvases' without having them overlap within a predefined div on the page. I have been attempting to find a way to make them act like block elements, but so far I haven't found a solution. Each new raphael object ends up positioned outside of any div.

Below is the HTML code:

...
#content{height:100%; width:980px; margin:0 auto;}
</style>
</head>
<body>
    <div id="content"></div>
...

and the javascript code:

var previews = [];
var prevSize = 25;
var spacing = 10;

//get container
var container =  document.getElementById('content');

//get container width
var containerWidth = parseInt(getComputedStyle(container,"").getPropertyValue('width'));

var prevsPerRow =containerWidth/(prevSize+spacing);
var rowsPerPage = 20;

for(var y=0; y<rowsPerPage-1; y++){
    for(var x=0; x<prevsPerRow; x++){
        var preview = Raphael((x*prevSize)+(x*spacing), (y*prevSize)+(y*spacing),prevSize, prevSize);
        previews.push(preview);
    }
}

for(var x=0; x<previews.length-1; x++){
    var temp = previews[x];
    var rectangle =temp.rect(0,0,prevSize,prevSize);
    rectangle.attr('fill','black');
}

One approach I'm considering is adjusting the x and y coordinates of the objects by adding the offset of the desired div, although this doesn't seem optimal.

Thank you for your assistance!

Answer №1

Although it may be belated by two years, I felt compelled to provide an answer as the previous response seemed lacking. For those who may stumble upon this in the future, I recommend utilizing the element or element Id factory methods offered by raphael, which can be found here.

The webpage provides the following examples:

// The code snippets below demonstrate how to create a canvas
// with dimensions of 320px width and 200px height.
// The first canvas is positioned at coordinates 10,50 within the viewport.
var paper = Raphael(10, 50, 320, 200);
// The second canvas is placed at the top left corner of the #notepad element
// (or its top right corner if using dir="rtl")
var paper = Raphael(document.getElementById("notepad"), 320, 200);
// Similar to the example above
var paper = Raphael("notepad", 320, 200);
// Image dump illustration
var set = Raphael(["notepad", 320, 200, {
    type: "rect",
    x: 10,
    y: 10,
    width: 25,
    height: 25,
    stroke: "#f00"
}, {
    type: "text",
    x: 30,
    y: 40,
    text: "Dump"
}]);

Answer №2

One interesting approach is to utilize a unique container for each new canvas that you create.
An illustrative example can be found below, demonstrating the addCanvas function being used to generate each individual element:

It's worth noting that the spacing and dimensions of the canvas blocks are set in the CSS styling.
