how about a class something like:
public class My_PageDrawer : org.apache.pdfbox.pdfviewer.PageDrawer
{
public void drawPage(System.Drawing.Graphics g,
org.apache.pdfbox.pdmodel.PDPage p,
java.awt.Dimension pageDimension){
//logic very similar to that in the Java version ...
}
protected override void
processTextPosition(org.apache.pdfbox.util.TextPosition text)
{
//Translation of the one in pageDrawer.java to handle .NET
graphics object
}
public override void fillPath(int windingRule)
{
//translation to .Net objects
}
//etc.
}
