Hi iTexters,
during the last week I was doing exactly a PdfGraphics class as you seem to have done.
I was only implementing the features which we currently are using. Especially I was
cheating with the FontMetrics. Now I realized this morning that you have done a more
complete implementation in the PdfGraphics2D, reason enough for me to abandom my
implementation and switch to the far more complete one of iText. But the problem I'm
observing is show in the following code:
/**
* <code>createPdf</code> prints a set of pages into the PDF
* file.
*/
public void createPdf() {
// make an instance of a PdfGraphics Object for the document
DefaultFontMapper fm = new DefaultFontMapper();
java.awt.Graphics2D g = null;
// don't do anything if pageable is null
if (pageable != null) {
// read all fonts recognized be iText in system font path
fm.insertDirectory(sun.awt.font.NativeFontWrapper.getFontPath(true));
System.out.println("PdfJob.createPdf: started");
int pages = pageable.getNumberOfPages();
System.out.println("PdfJob.createPdf: pages to print:
"+pages+"\n");
// set pageSize of first page before the document opens!!
float width =
(float)pageable.getPageFormat(0).getPaper().getWidth();
float height =
(float)pageable.getPageFormat(0).getPaper().getHeight();
theDocument.setPageSize(new Rectangle(width, height));
// g.setPageSize(pageable.getPageFormat(0));
theDocument.open();
g = pdfWriter.getDirectContent().createGraphics(width, height,
fm);
for (int p = 0; p < pages ; ++p) {
Printable thePage = pageable.getPrintable(p);
try {
// print!
thePage.print(g, pageable.getPageFormat(p), p);
System.out.println("PdfJob.createPdf: page "
+ p + " printed");
if (p < pages-1) {
// next page, please! on its proper
PageSize
width =
(float)pageable.getPageFormat(p+1).getPaper().getWidth();
height =
(float)pageable.getPageFormat(p+1).getPaper().getHeight();
theDocument.setPageSize(new
Rectangle(width, height));
} // end of if (p < pages-1)
theDocument.newPage();
////////////////////////////////////////////////////////

g =

}
} // end of for (int p = 0; p < pages; p++)
