Maybe I said that incorrectly.
The problem is NOT that I cant resize Image (its easy).
The problem is that method
Slide.draw(Graphics g)
draws relatively small image (ie 800x600) and resizing it to 1024x768 is
useless because of poor quality or fesult (bitmap is not vector)
and I cant figure out how to set default Slide' default draw resolution
to 1024x768. so I can draw image in right quality (slides in PPT have
good quality).

I know absolutly nothing about Powerpoint nor about the POI api that supports
it but I would have thought that once you have the image then you should use
the standrd Java API and I am confident that if you searched for code that
told you how to resize an image using Java then you should find some help.
Just did that myself and came across these links, one may help;

Hi, All!
I am using POI to display slides from PPT as Images in swing.
And I have a problem with size of images I get from draw method of
Slide class.
I would like to set size of received image as 1024x768 but I do not
know how to do this (by default it has smaller dimensions).
*SlideShow ppt = new SlideShow(new HSLFSlideShow(new
FileInputStream(file)));*
//ppt.setPageSize(new Dimension (1024,768)); // extends
size of slides but do not fit content
Dimension pgsize = ppt.getPageSize();
*Slide[] slide = ppt.getSlides();*
BufferedImage img = new BufferedImage(pgsize.width,
pgsize.height, BufferedImage.TYPE_INT_RGB);
Graphics2D graphics = img.createGraphics();
graphics.setPaint(Color.white);
graphics.fill(new Rectangle2D.Float(0, 0, pgsize.width,
pgsize.height));
*slide[0].draw(graphics);*
ImageIcon icn = new ImageIcon(img);
Is it possible to draw images in given dimensions?
If yes, how to do it ?
Best Regards
