Description

I switched from 1.7.1 to 1.8.0-SNAPSHOT. Following code did not work any longer:

@Test
public void testGenerateNewDocument() throws IOException, COSVisitorException {
PDDocument doc = null;
try

{ doc = new PDDocument(); PDPage page = new PDPage(); doc.addPage(page); PDFont font = PDType1Font.HELVETICA_BOLD; PDJpeg image = new PDJpeg(doc, getLogoInputStream() ); PDPageContentStream contentStream = new PDPageContentStream(doc, page, true, true); contentStream.beginText(); contentStream.setFont(font, 12); contentStream.moveTextPositionByAmount(100, 700); contentStream.drawString("Hello World!"); contentStream.endText(); contentStream.drawImage(image, 20, 20); contentStream.close(); doc.save( getWorkDirectory() + File.separator + "pdfbox-testGenerateNewDocument.pdf" ); }

finally {
if (doc != null)

{ doc.close(); }

}
}
