Subject Re[2]: org.apache.poi.hslf.model.TextRun

Hi

TextRun is just a holder of the text. If you want to work with shapes
you should use Slide.getShapes() which returns a collection of shapes
in the slide:


        SlideShow ppt = new SlideShow(new HSLFSlideShow(filename));

        Dimension pgsize = ppt.getPageSize(); //page size
        
        Slide sl = ppt.getSlides()[0];
        Shape[] sh = sl.getShapes();
        for (int i = 0; i < sh.length; i++) {
            //anchor of the shape
            java.awt.Rectangle anchor = sh[i].getAnchor();
            
            if (sh[i] instanceof TextBox){
               TextBox box = (TextBox)
               String text = box.getText();
               String font = box.getFontName();
               int size = box.getFontSize();
               ...
            }
       }

Warning: In the current implementation  you can get text attributes only if
they are explicitly set. For example, if you don't change the default
font size box.getFontSize() return -1 which means n/a. In this case PowerPoint
uses the default font size which is stored in special container
TxMasterStyleAtom which is not decoded yet.
Also the object model for working with character/paragraph attributes
is likely to change. Current code is rather demonstration of
capabilities, not the final version.


Some documentation is available at
