The .ppt file that causes all this mess
Hello I'm currently using Apache POI HSLF to convert in application to convert
flowchart Powerpoint files (.ppt) into .png image files. It works ok, normally,
without arrows usually, but I found a new crash while converting a .ppt file.
I have no idea why this is happening.
The sentence that throws NullPointerException is:
/* Code Start */
FileInputStream is = new FileInputStream("greenpe.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();
graphics.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
RenderingHints.VALUE_ANTIALIAS_ON);
graphics.setRenderingHint(RenderingHints.KEY_RENDERING,
RenderingHints.VALUE_RENDER_QUALITY);
graphics.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
RenderingHints.VALUE_INTERPOLATION_BICUBIC);
graphics.setRenderingHint(RenderingHints.KEY_FRACTIONALMETRICS,
RenderingHints.VALUE_FRACTIONALMETRICS_ON);
graphics.setPaint(Color.white);
graphics.fill(new Rectangle2D.Float(0, 0, pgsize.width, pgsize.height));
Slide s = slide[i];
try {
s.draw(graphics);
} catch (NullPointerException e) {
e.printStackTrace;
}
/* Code Finish */
This is the stack trace:
