Re-editing a BufferedImage

Question

Hello,
I am creating a program that uses buffered images with part of the image transparent and part of it solid.
What I need to do, is define an image with solid and transparent areas and then later, re-edit the image so that I can define new transparent and solid areas.
Here is what I am trying to do.
BufferedImage bi = new BufferedImage(100,100,BufferedImage.TYPE_INT_ARGB);
Graphics g = bufferedImage.getGraphics();
g.setColor(Color.white);
g.fillRect(0,0,100,100); // Trying to set the image blank
g.setColor(new Color(1f,0f,0f,0f)); // Transparent Color
g.fillRect(0,0,100,100);When I attempt to clear the image by painting a white rectangle followed by a drawing another rectangle using the transparent color,
the solid color is still shown.
How do I completly clear the image?
Thanks
Andrew

Hi there,
As regards getting the image as a component, I haven't
had much success - so am trying another route.Define "much success" - can't you use the library to display PDFs ?
BufferedImage out = new BufferedImage(250, 250,
BufferedImage.TYPE_INT_RGB);
Graphics g2d = out.getGraphics();
g2d.drawBytes(bytes, 0, 0, 250, 250);...
Does this image gets black ? To be quite honest, the code does not makes too much sense for me. It seems you're getting the bytes from the PDF file (which are coded in PDF) and dumping them on the buffered image (which expects RGB triplets, I guess). How/where is the conversion/rendering code ?
