Re: Centreing and Rotating Text

Hi Paul,

The rotation point is the defined lat/lon point, so if you want to
control where your text is relative to that point, you can use a offset
render type, where you give a pixel offset as well as the lat/lon
point. I don't think you'd have to give a horizontal offset if you
choose center justification, but you might have to supply a vertical
offset to put the center of the text on the lat/lon point. You also may
have to create the OMText object, generate it to figure out how tall it
is (pixelwise), and then reset the vertical offset and regenerate().
You should only have to do that once, though.

Cheers,

Don
