Hi List
Playing around with GTRenderer and trying to output an SVG document
with texts NOT rendered as shapes. "new SVGGraphics2D()" parameter
textAsShapes set to FALSE and also hint TEXT_RENDERING_KEY set to
TEXT_RENDERING_STRING. Vector data being outputted is SHP files with
SLD styles.
any help would be appreciated
thanks,
Udo
