Hello, I have following situation: I read Points (geometry type) from Postgis, style them with SLD and render on JMapFrame. I use min and max scale denominator to draw points with external graphic with different size. 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?
I would appreciate if someone can help me about this issues.
