Thanks Michael,

What about SLD and his way of styling data. Is it somehow possible 
to get width and height of graphic symbol in pixels on map?
Say that we have .png image and that we define <sld:Size>100</sld:Size> 
to that image. Is it possible to know graphic height and width in pixels
from 
that information?
I need that because i want to catch mouse events when user enters and exits 
that graphic symbol and show some pop-up window with informations on mouse
entered.

Best regards.



That helps me much. 
What i need to know in every moment are SCREEN coordinates of external
graphic (which is used in SLD), depending on current map scale. I need to
get bounding box around external graphic in screen coordinates depending on
map scale. This is because external graphic object is of different size for
different
map scales.
What i have are world coordinates of center for every point. I am curious is
it
possible to get screen coordinates from world coordinates and current map
scale?
Also when we specify size of external graphic in SLD with
<sld:Size></sld:Size> is
it possible to get graphic height and width in pixels from it?
