  1. POI-HSLF Java API To Access Microsoft PowerPoint Format Files Yegor Kozlov yegor - apache - org

  2. What is HSLF? • HorribleSLideshowFormat is the POI Project's pure Java implementation of the Powerpoint '97(-2007) file format. • POI sub-project since 2005

  3. HSLF in a Nutshell • HSLF provides a way to read, create and modify MS PowerPoint presentations • Pure Java API - you don't need PowerPoint to read and write *.ppt files • Comprehensive support of PowerPoint objects • Rich text • Tables • Shapes • Pictures • Master slides • Access to low level data structures

  4. The source code is available at http://people.apache.org/~yegor/apachecon_eu08/

  5. HSLF in Action - 1Data Extraction • Text from slides and notes • Images • Shapes and their properties (type, position in the slide, color, font, etc.)

  6. HSLF in Action - 2 Creating a simple presentation from scratch SlideShow ppt = new SlideShow(); Slide slide = ppt.createSlide(); TextBox box2 = new TextBox(); box2.setHorizontalAlignment(TextBox.AlignCenter); box2.setVerticalAlignment(TextBox.AnchorMiddle); box2.getTextRun().setText("Java Code"); box2.getFill().setForegroundColor(new Color(187, 224, 227)); box2.setLineColor(Color.black); box2.setLineWidth(0.75); box2.setAnchor(new Rectangle(66, 243, 170, 170)); slide.addShape(box2); TextBox box3 = new TextBox(); box3.setHorizontalAlignment(TextBox.AlignCenter); box3.setVerticalAlignment(TextBox.AnchorMiddle); box3.getTextRun().setText("*.ppt file"); box3.setLineWidth(0.75); box3.setLineColor(Color.black); box3.getFill().setForegroundColor(new Color(187, 224, 227)); box3.setAnchor(new Rectangle(473, 243, 170, 170)); slide.addShape(box3); AutoShape box4 = new AutoShape(ShapeTypes.Arrow); box4.getFill().setForegroundColor(new Color(187, 224, 227)); box4.setLineWidth(0.75); box4.setLineColor(Color.black); box4.setAnchor(new Rectangle(253, 288, 198, 85)); slide.addShape(box4); FileOutputStream out = new FileOutputStream("hslf-demo.ppt"); ppt.write(out); out.close();

  7. Java Code *.ppt file

  8. Wait, there is more! • Rich text • Tables • Pictures (JPEG, PNG, BMP, WMF, PICT) • Comprehensive formatting features

  9. HSLF in Action - 3 PPGraphics2D: PowerPoint Graphics2D driver //bar chart data. The first value is the bar color, the second is the width Object[] def = new Object[]{ Color.yellow, new Integer(100), Color.green, new Integer(150), Color.gray, new Integer(75), Color.red, new Integer(200), }; SlideShow ppt = new SlideShow(); Slide slide = ppt.createSlide(); ShapeGroup group = new ShapeGroup(); //define position of the drawing in the slide Rectangle bounds = new java.awt.Rectangle(200, 100, 350, 300); group.setAnchor(bounds); slide.addShape(group); Graphics2D graphics = new PPGraphics2D(group); //draw a simple bar graph int x = bounds.x + 50, y = bounds.y + 50; graphics.setFont(new Font("Arial", Font.BOLD, 10)); for (int i = 0, idx = 1; i < def.length; i+=2, idx++) { graphics.setColor(Color.black); int width = ((Integer)def[i+1]).intValue(); graphics.drawString("Q" + idx, x-20, y+20); graphics.drawString(width + "%", x + width + 10, y + 20); graphics.setColor((Color)def[i]); graphics.fill(new Rectangle(x, y, width, 30)); y += 40; } graphics.setColor(Color.black); graphics.setFont(new Font("Arial", Font.BOLD, 14)); graphics.draw(bounds); graphics.drawString("Performance", x + 70, y + 40); FileOutputStream out = new FileOutputStream("hslf-demo.ppt"); ppt.write(out); out.close();

  10. Q1 100% Q2 150% Q3 75% Q4 200% Performance

  11. HSLF Development Plans • Support for more PowerPoint functionality • Rendering slides into java.awt.Graphics2D • A way to export slides into images or other formats • Integration with Apache FOP - Formatting Objects Processor • Transformation of XSL-FO into PPT • PPT2PDF transcoder
