PrintTranscoder.KEY_AOI problem posible bug

[Bartosz Celmer]

Hello I’m trying to use Batik project to print SVG documents, but I need to print only part of them. I tried to use PrintTranscoder.KEY_AOI, but I doesn’t work. When I set a rectangle which I want to print either nothing is being printed, or the printed area is different from the one I choose. Here is the code I use to print:     private void print()  {        new Thread() {       public void run(){       Rectangle aoi = new Rectangle(0,0,200,200);       PrintTranscoder pt= new PrintTranscoder();           pt.addTranscodingHint(PrintTranscoder.KEY_WIDTH,                                  new Float(aoi.width));        pt.addTranscodingHint(PrintTranscoder.KEY_HEIGHT,                                  new Float(aoi.height));             pt.addTranscodingHint(PrintTranscoder.KEY_AOI, aoi);         TranscoderInput input = new TranscoderInput(document);           pt.addTranscodingHint(pt.KEY_SHOW_PAGE_DIALOG,Boolean.TRUE);         pt.addTranscodingHint(pt.KEY_SHOW_PRINTER_DIALOG,Boolean.TRUE);         pt.transcode(input, null);                  try {pt.print();         }         catch (Exception ex)         {                   }         }       }.start(); }   My SVG example looks like this:   <?xml version="1.0" encoding="iso-8859-1" standalone="no"?> <!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 20001102//EN" "http://www.w3.org/TR/2000/CR-SVG-20001102/DTD/svg-20001102.dtd"> <svg viewBox="0 0 400 400" >             <g id="relief" visibility="visible">                         <rect x="10" y="10" width="390" height="390" fill="none" stroke="black" stroke-width="2"/>                         <circle style="fill:none;stroke:black;" cx="200" cy="200" r="100"/>             </g>             <g id="c" visibility="hidden">                         <text x="200" y="200" style="font-family: sans-serif; font-size: 14pt; stroke: none; fill: black;">Center</text>             </g>             <text x="50" y="50" style="font-family: sans-serif; font-size: 14pt; stroke: none; fill: black;">UL</text>             <text x="50" y="350" style="font-family: sans-serif; font-size: 14pt; stroke: none; fill: black;">BL</text>             <text x="350" y="50" style="font-family: sans-serif; font-size: 14pt; stroke: none; fill: black;">UR</text>             <text x="350" y="350" style="font-family: sans-serif; font-size: 14pt; stroke: none; fill: black;">BR</text>             <line x1="190" y1="10" x2="190" y2="190" stroke="black" stroke-width="2"/>             <line x1="10" y1="190" x2="190" y2="190" stroke="black" stroke-width="2"/> </svg>     When I set: Rectangle aoi = new Rectangle(0,0,200,200); the area is smaller then one I choose. When I set: Rectangle aoi = new Rectangle(200,200,200,200); nothing is being printed.   Please give me any suggestion what I’m doing wrong. Thanks Bartek
