AW: [OpenLayers-Users] symbol truncated on tile borders of WMS

gutter is a client-side option. It tells OpenLayers to request larger tiles
from the WMS Server. This way it is possible to minimalize truncated symbols
at the edges of the tiles.
 
var wmsLayer = new OpenLayers.Layer.WMS(name, url, {layers:'...',
version:'1.1.1'}, {gutter:10});

Most of my layers are WMS that I don't have control on. 
I'm wondering why I don't set singleTile: true to all my WMS
connection...... 

What could be the issues if I set singleTile: true to all my layers? 
thanks 
Steve

set gutter:10 in the options of your wms layer. 
  
  
OpenLayers\Layer.js 
  
    /**
    * APIProperty: gutter
    * {Integer} Determines the width (in pixels) of the gutter around image
    *     tiles to ignore.  By setting this property to a non-zero value,
    *     images will be requested that are wider and taller than the tile
    *     size by a value of 2 x gutter.  This allows artifacts of rendering
    *     at tile edges to be ignored.  Set a gutter value that is equal to
    *     half the size of the widest symbol that needs to be displayed.
    *     Defaults to zero.  Non-tiled layers always have zero gutter.

   gutter: 0,

Hi, 
When I draw a WMS with singleTile: false, the symbols are truncated along
the edges of the tiles. 
I read that we can use partial false for labels but is there somethig we can
do for symbols? 
thanks 
Steve
