Google maps api v3: text location on the MarkerClusterer icon

Question

I am trying to set a different position for the text displayed in the MarkerClusterer icon when the calculator function starts. Is it possible to move the text to the top of the icon a little more?

How can i do this?

thank!

I assume that you are using the code that I think you are using googles markercluster .. in this case, you need, for example, to take the code markerclusterer.js and change it directly.

ClusterIcon.prototype.createCss() ..., ( divs). , , , line-height.

:

/**
 * Create the css text based on the position of the icon.
 *
 * @param {google.maps.Point} pos The position.
 * @return {string} The css style text.
 */
ClusterIcon.prototype.createCss = function(pos) {

  var style = [];
  style.push('background-image:url(' + this.url_ + ');');
  var backgroundPosition = this.backgroundPosition_ ? this.backgroundPosition_ : '0 0';
  style.push('background-position:' + backgroundPosition + ';');

  if (typeof this.anchor_ === 'object') {
    if (typeof this.anchor_[0] === 'number' && this.anchor_[0] > 0 &&
        this.anchor_[0] < this.height_) {
      style.push('height:' + (this.height_ - this.anchor_[0]) +
          'px; padding-top:' + this.anchor_[0] + 'px;');
    } else {

      //
      // See the (this.height_ - 10) for line-height
      //

      style.push('height:' + this.height_ + 'px; line-height:' + (this.height_ - 10) +
          'px;');
    }
    if (typeof this.anchor_[1] === 'number' && this.anchor_[1] > 0 &&
        this.anchor_[1] < this.width_) {
      style.push('width:' + (this.width_ - this.anchor_[1]) +
          'px; padding-left:' + this.anchor_[1] + 'px;');
    } else {
      style.push('width:' + this.width_ + 'px; text-align:center;');
    }
  } else {

    //
    // See the (this.height_ - 10) for line-height
    //

    style.push('height:' + this.height_ + 'px; line-height:' +
        (this.height_ - 10) + 'px; width:' + this.width_ + 'px; text-align:center;');
  }

  var txtColor = this.textColor_ ? this.textColor_ : 'black';
  var txtSize = this.textSize_ ? this.textSize_ : 11;

  style.push('cursor:pointer; top:' + pos.y + 'px; left:' +
      pos.x + 'px; color:' + txtColor + '; position:absolute; font-size:' +
      txtSize + 'px; font-family:Arial,sans-serif; font-weight:bold');

  return style.join('');
};

, , HTML- div, :

<div style="background-image: url(http://google-maps-utility-library-v3.googlecode.com/svn/trunk/markerclusterer/images/m1.png); height: 53px; line-height: 43px; width: 53px; text-align: center; cursor: pointer; top: 173.68359152317203px; left: 273.60742400000004px; color: black; position: absolute; font-size: 11px; font-family: Arial, sans-serif; font-weight: bold; background-position: 0px 0px;">2</div>

.. - c. line-height: 43px;

, div css. , 2 , 2 div. , , , :

/**
 * Adding the cluster icon to the dom.
 * @ignore
 */
ClusterIcon.prototype.onAdd = function() {
  this.div_ = document.createElement('DIV');
  if (this.visible_) {
    var pos = this.getPosFromLatLng_(this.center_);
    this.div_.style.cssText = this.createCss(pos);

    // For debugging purposes so you know what you are doing
    // console.log(this.div_);

    // The interesting part here is the this.div_.innerHTML    
    // You could for example add more elements inside this.div_, 
    // now it just adds the number

    this.div_.innerHTML = this.sums_.text;
  }

  var panes = this.getPanes();
  panes.overlayMouseTarget.appendChild(this.div_);

  var that = this;
  google.maps.event.addDomListener(this.div_, 'click', function() {
    that.triggerClusterClick();
  });
};
