[GoogleCodeExporter]

 I have function  

//Function: formatTextPortait
//format text portait or landscape
//
//Parameters:
//@portait 
//if true is format text portait else format text landscape
//
this.formatTextPortait = function( portait) {

    var elem = selectedElements[0];
    if (elem == null) {
        return;
    }

    var d = document.getElementById(elem.id);
    var childNodeArray = document.getElementById(elem.id).childNodes;
    var c = textManager.textArray[0];
    var index =0;
    if (portait){

        //childNodeArray.item(0).textContent = $('#textDisplay').val();
        //elem.textContent =$('#textDisplay').val();                
        for (i = 0; i< childNodeArray.length ; i++){
            var tspan = document.getElementById(childNodeArray.item(i).id);
            var dxArray = "0";
            var dyArray = "0";
            for (j=0; j< tspan.textContent.length ; j++) {
                 c = textManager.textArray[index];
                 if (c.width ==0){
                     index++;
                     c = textManager.textArray[index];
                 }
                dxArray = dxArray + ' -' + c.width;
                dyArray = dyArray + " "+newDy;
                index ++;
            }
            tspan.setAttribute('dx', dxArray );
            tspan.setAttribute('dy',dyArray );
            tspan.setAttribute('x', elem.getAttribute('x')  -(newDy+4)*i);
            tspan.setAttribute('y', elem.getAttribute('y') );
        }
    }else {
        //childNodeArray.item(0).textContent = $('#textDisplay').val();
        //elem.textContent =$('#textDisplay').val();                
        for (i = 0; i< childNodeArray.length ; i++){
            var tspan = document.getElementById(childNodeArray.item(i).id);

            tspan.setAttribute('dx', "0" );
            tspan.setAttribute('dy',newDy );
            tspan.setAttribute('x', elem.getAttribute('x'));
            tspan.setAttribute('y', "" );
        }
    }

}

text portait.
