Example how to setup a correct drawingenvironment.

Hello in the quicktime-list!

I am trying to create an imagefile using the code below.
can anyone give me a hint, how I setup a QDGraphics and
a corresponding ImageDescription, before using the Exporter?
(perhaps some person at apple reading this?)
I am pretty much frustrated by now, from the bad documentation
and the pretty old examples e.g. the ZOO-example which needed
mayor repair from me to get it to work a little bit!

there must be some way to tell the exporter or the graphics,
how many colors, which resolution and so forth...
..has someone an examplecode for this? because working through all
this huge api is not that easy.

regards,
helge.

QDRect areaToUse = new QDRect( 200, 150 );
QDGraphics myDrawingBoard = new QDGraphics( areaToUse );
myDrawingBoard.setBackColor( QDColor.red );
boundaries = myDrawingBoard.getBounds();
width = boundaries.getWidth();
height = boundaries.getHeight();
ovalwidth = 20;
ovalheight = 20;
boundaries.setWidth( width-10 );
boundaries.setHeight( height-10 );
boundaries.setX( boundaries.getX()+5 );
boundaries.setY( boundaries.getY()+5 );
qdg.setForeColor( QDColor.blue );
try {
myDrawingBoard.paintRoundRect( boundaries, ovalwidth, ovalheight );
}
catch( Exception ex ) {
System.out.println( "Main.produceAnImage: Exception ="+ex.getMessage() );
}
ImagePresenter imgpres = ImagePresenter.fromGWorld( myDrawingBoard );
EncodedImage img = imgpres.getImage();
QTHandle qth = QTHandle.fromEncodedImage( img );
ImageDescription imgdesc = new ImageDescription(0);
imgdesc.setFrameCount(1);
imgdesc.setHeight( height );
imgdesc.setWidth( width );
imgdesc.setHRes(new Float(75.0).floatValue());
imgdesc.setVRes(new Float(75.0).floatValue());
imgdesc.setDepth(quicktime.std.StdQTConstants.codecInfoDepth16 );


GraphicsExporter graphicsExporter = new GraphicsExporter(quicktime.std.StdQTConstants.kQTFileTypeJPEG);
//graphicsExporter.setInputGWorld( myDrawingBoard );
graphicsExporter.setInputHandle( qth, imgdesc );
// graphicsExporter.requestSettings();
graphicsExporter.setOutputFile (new QTFile("/tmp/test_changed.jpg"));
// sets the destination for image file
int size = graphicsExporter.doExport();
