color:#1F497D'>In another approach, I believe MapServer wants you to define a
bounding box for the circle by creating a line shape with the first point at
the UL coordinate of that box and the second coordinate at the LR coordinate of
the box. So you’d offset your center point .5 KM to create those points.
You can add the resulting shape to the appropriate layer to draw it.<o:p></o:p></span></p>

<b>Subject:</b> [mapserver-users] How to draw a circle using MapScript?</span><o:p></o:p></p>
<div>
<p class=MsoNormal>Hello List,<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>I want to be able to draw a circle dynamically using PHP
MapScript. The circle is defined by the coordinates of the centre and the
radius in kilometers. I realize that the circle is a polygon and I should
probably calculate all points. What is the best way to do it? <o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>I would really appreciate any help!<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>Thank you,<o:p></o:p></p>
<p class=MsoNormal>Helen<o:p></o:p></p>
