Re: [iText-questions] Changing the size of a PDFTemplate

Hey Paulo,

I added the following lines to create my custom footer inside of PdfDocument

float w = (footer.getMiddle()).font().getBaseFont().getWidthPoint(pageNumberMaxChars,(footer.getMiddle()).font().size());
float h = (footer.getMiddle()).font().size();
footerPageNumberTemplate = (writer.getDirectContent()).createTemplate(w,h);
footerPageNumberTemplate.setFontAndSize((footer.getMiddle()).font().getBaseFont(),footer.getMiddle()).font().size());
footerPageNumberImage = Image.getInstance(footerPageNumberTemplate);
footerPageNumberChunk = new Chunk(footerPageNumberImage,0,0);
footerParagraph.addSpecial(footerPageNumberChunk);
The following variables are private variables in the PdfDocument.  So I can save the references.
footerPageNumberTemplate
footerPageNumberImage
footerPageNumberChunk
pageNumberMaxChars ------ is a variable holding "000000", as a default width for the template.

I used an image to contain the footerPageNumberTemplate so that the text will flow around the template naturally, and since I don't know the exact location to place the template.

Then in the close funciton I back patch the template since I now know the number.

Rectangle rec = footerPageNumberTemplate.getBoundingBox();
rec.setRight(6);
footerPageNumberTemplate.setBoundingBox(rec);
Image img = footerPageNumberChunk.getImage();
img.setRight(6);
footerPageNumberImage.setRight(6);
footerPageNumberTemplate.beginText();
footerPageNumberTemplate.showText(String.valueOf(writer.getPageNumber() - 1));
footerPageNumberTemplate.endText();
 
Obviously I need the width by calculating the width of the total number of pages.  However for testing purposes I just put in the value of 6.
 
How come the size of the template is not changing.  Or is it not possible to change the width once it has already been added to the document.
 
I have a patch for my changes to the latest CVS, and example files to show the output.  If you would like them to look at please let me know.
 
thanks
scott
