Power Point Viewer

[Túlio Severiano <tu...@gmail.com>]

I'm building a Power point viewer. That can also convert the slider in a JPG
or PNG.

I am using this example. But it does not display the background or text
formatting. Any help?

<http://poi.apache.org/slideshow/how-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();
        }

In the file poi-src-3.6-20091214.tar.gz

folder poi-src-3.6-20091214 \ poi-3.6 \ test-data \ slideshow

Missing_core_records.ppt that contains the file I'm using as an example of
studies.

I can not get the background, only solid colors.

This part of the api is about to get a little attention as I am scratching an itch in this same area.

Please share what shapes are not working correctly for you.

If it is possible please attach some simple examples of slides that don't render properly to a bugzilla entry.

Dave

I suspect that these are bits that still need work. Your best bet is to 
identify the shape objects that make up the bits that aren't appearing, 
then add / update their draw methods to implement the missing 
functionality.

Do please share you patches when you get it working! :)
