zoom to svg area problem

[Bartosz Celmer]

Hello   I'm writing applet viewing SVG using batik 1.5.1. I need to write a function witch will zoom SVG document on SVGCanvas object to desier SVG coordinates, or return AffineTransform  object witch I can use to transform orginal SVG view to desire area. For example: my svg viewbox is: 0 0 200 200, and I want to zoom to: upperLeftX = 50, upperLeftY = 50, bottomRightX = 100, bottomRightY = 100   Function schould look like this. // upperLeft - upper left x,y SVG coordinates // bottomRight - bottom right x,y SVG coordinates // This two pair of coordinates is desier view SVGCanvas should zoom to. private AffineTransform setZoom(Point2D upperLeft, Point2D bottomRight) {     // funtion body   }   I know that AffineTransform uses screen coordinates to zoom SVG document on SVGCanvas. What I realy need is to know how to convert SVG coordinates to screen coordinates.   Could You send me any sugestions?   Thanks a lot   Bartosz Celmer
