BufferedImage suitable for paper onto my monitor

Question

I wrote this method for a program we have been using for about three years that makes and prints a BufferedImage:pBI.bufIm.
But I don’t do much programming, so I can’t remember a lot of java stuff.
Please don’t put me down too much like some people do.
I don’t know the correctness or bestness of this method or necessity of all statements, but it works.
      public int print(Graphics g,PageFormat pF,int pgIx)throws PrinterException { //implemented as the only method() in Printable
        if (pgIx >= 1) return Printable.NO_SUCH_PAGE; //pgIx is page index
        Graphics2D g2d=(Graphics2D)g; g2d.translate(pF.getImageableX(),pF.getImageableY()); //Set us to the upper left corner
        AffineTransform at=new AffineTransform();   at.translate(0,0);
        double xScale=pF.getImageableWidth()/papDotImXd,  yScale=pF.getImageableHeight()/papDotImYd; //scale for fit on one page
        at=at.getScaleInstance(xScale,yScale);
        g2d.drawRenderedImage(pBI.bufIm,at);
        return Printable.PAGE_EXISTS;
      }For the monitor I had made another "parallel" BufferedImage scaled for the monitor,
but I think that was just extra work and I don’t need the second BufferedImage.
I painted it with the following method.
      public void paint(Graphics fGcontext) { //fGcontext=this.getGraphics(); where this is extended (subclassed) Frame
        if((sBI.bufIm!=null)&&(fGcontext!=null))fGcontext.drawImage(sBI.bufIm,fInsets.left,fInsets.top,this);
      } In my next program I would like to render the paper BufferedImage and show it on the screen.
My problem is I don’t know the code to do that,
but I think it must be not much longer than the print() method above.
I have code to get the screen and Frame size that I used already.
Would someone write an example small method to show me how to put a copy to screen?

Answer 1

With a little thinking, looking-up, and trial-and-error, I got something that worked.
      public void screenView(BufferedImage papBI,Graphics fGcontext) { //implemented as the only method() in Printable
        Graphics2D g2d=(Graphics2D)fGcontext; g2d.translate(scrDotImXp,scrDotImYp);
        AffineTransform at=new AffineTransform(); at.translate(0,0); //Set us to the upper left corner
        double xScale=scrDotImXd/(double)papDotImXd,  yScale=scrDotImYd/(double)papDotImYd;
        at=at.getScaleInstance(xScale,yScale);
        g2d.drawRenderedImage(pBI.bufIm,at);
      public void paint(Graphics fGcontext) {
        if(fGcontext!=null)screenView(pBI.bufIm,fGcontext);
      } But the picture quality is not good enough for me.
So I will stick with two BufferedImage.
But comments will still be appreciated.
