wrap text to fit into a rectangle : raphael

问题

Anyone know of function that can break text at word boundaries to fit into rectangle

Following is code for rectangle and text

  window.onload = function () { 

    var outsideRectX1=30, outsideRectY1=30,outsideRectX2=220, outsideRectY2=480, outsideRectR=10;
    var group = paper.set();


    var rect1=paper.rect(outsideRectX1+40, outsideRectY1+70, 80, 40,10);
    var text3=paper.text(outsideRectX1+75, outsideRectY1+85,"Test code for wrap text").attr({fill: '#000000', 'font-family':'calibri', 'font-size':'14px'});

    group.push(rect1);
group.push(text3);

     };

When text is greater than rectangle width it automatically wrap so that it always display into rectangle boundaries.

I'm not sure whether there is any direct way to wrap the text according to the size of the rectangle. May be you can specify line breaks or a "\n". Or you can try to resize the rectangle as and when the text length increases.

Here is a sample code where the rectangle resize as the text length increases.

var recttext = paper.set();
el = paper.rect(0, 0, 300, 200);
text = paper.text(0,10, "Hi... This is a test to check whether the rectangle dynamically changes its size.").attr({"text-anchor":"start",fill:'#ff0000',"font-size": 14});
text1=paper.text(0,30,"hi").attr({"text-anchor":"start",fill: '#ff0000',"font-size": 14});
//el.setSize(495,200);
recttext.push(el);
recttext.push(text);
recttext.push(text1);
alert(recttext.getBBox().width);
alert(recttext.getBBox().height);
var att = {width:recttext.getBBox().width,height:recttext.getBBox().height};
el.attr(att);
recttext.translate(700,400);

I know it's a little belated now, but you might be interested in my [Raphael-paragraph][1] project.

It's a small library that allows you to create auto-wrapped multiline text with maximum width and height constraints, line height and text style configuration. It's still quite beta-ish and requires a lot of optimization, but it should work for your purposes.

Usage examples and documentation are provided on the GitHub page.
