$h = $map->height;<br>

$x = $map->width / 2;<br>

$centerPixel = new pointObj();<br>

$map->zoomScale($scale, $centerPixel, $map->width,

I get good pdf maps which print accurately to scale using this
method.<br>

<br>
I am trying to create an image with same size as the map extent,
only by a scale factor of 500.
<br>
The mapserver scale computation gives 500.8989383487 scale.
<br>
<br>
If I set the image inch*72.129302863661 instead of default 72 the
mapsever scale computed is
<br>
500.00127000041.
<br>
<br>
What is the correct value for resolution?
<br>
