Pan map by pixel (offset map centering)

MartinSirkovsky

I would like to offset the map recentering by x number of pixels. How can I do this.

map.centerAt(point) - The argument takes a coordinates. However I would like to move the center 50 px to the left from real center.

I guess I could calculate the resolution of the pixel based on the current map scale and than calculate the distance I need to move the map. But I am wondering if there is a simpler way of panning the map by defining number of pixels, rather than the coordinates at which to center.

Thanks,
Martin

Thanks for the tip. I investigating further after I posted my question and that is what I used.

Here is my code, using Jquery selectors:

// Get width of map div  var mapDivWidth = $("#mapDiv").width();  // Get width of the div which is partialy obscuring the mapDiv var tableListWidth = $("#propertyList").width();  // Get the min and max X coordinate of the current map  var minX = map.toMap(esri.geometry.ScreenPoint(0,0)); var maxX = map.toMap(esri.geometry.ScreenPoint((mapDivWidth-1),0));  // Calculate the current pixel resolution var pointResolution = (maxX.x - minX.x)/mapDivWidth;   // Get the correct map center var currentMapCenter = (mapDivWidth - tableListWidth) / 2;  // Get the wished offset in coordinate system units offset = ((mapDivWidth / 2) - currentMapCenter) * pointResolution;  //...... follows the code where I apply the offset
