Regarding converting a PPT Slide to JPG/PNG

[Amol Tiwari]

Hi,

 

I have seen the earlier mailing list posts on how converting a PPT slide into 
JPG was not possible. ( I am referring to the list at: 
http://mail-archives.apache.org/mod_mbox/poi-user/200611.mbox/thread)

 

I have also read a code snippet which is trying to achieve this. (I am 
referring to http://poi.apache.org/hslf/how 
<http://poi.apache.org/hslf/how-to-shapes.html#Render> -to-shapes.html#Render)

 

FileInputStream is = new FileInputStream("slideshow.ppt");
        SlideShow ppt = new SlideShow(is);
        is.close();
        
        Dimension pgsize = ppt.getPageSize();
 
        Slide[] slide = ppt.getSlides();
        for (int i = 0; i < slide.length; i++) {
 
            BufferedImage img = new BufferedImage(pgsize.width, pgsize.height, 
BufferedImage.TYPE_INT_RGB);
            Graphics2D graphics = img.createGraphics();
            //clear the drawing area
            graphics.setPaint(Color.white);
            graphics.fill(new Rectangle2D.Float(0, 0, pgsize.width, 
pgsize.height));
 
            //render
            slide[i].draw(graphics); 
 
            //save the output
            FileOutputStream out = new FileOutputStream("slide-"  + (i+1) + 
".png");
            javax.imageio.ImageIO.write(img, "png", out);
            out.close();
        }

 

The line marked Red (Slide[i].draw(graphics) ) is not correct. Does anyone have 
a working model for this code?

 

 

Can anyone help me with this? Is it possible with the recent build? (I am using 
\poi-bin-3.0.2-FINAL-20080204\poi-3.0.2-FINAL)

 

Thanks and Regards!

 

Amol.
