Here is what I came up with :
Note that I'm passing a TIFF document as byte[] and expecting a PDF document as
byte[]
My question is: Is this correct? Can I remove the formatting stuff in there?
Thank you gurus for sharing your valuable and priceless insight!
public byte[] convert(byte[] documentByteArray) {
Document document = new Document();
try {
ByteArrayOutputStream output = new ByteArrayOutputStream();
PdfWriter writer = PdfWriter.getInstance(document, output);
int pages = 0;
document.open();
PdfContentByte cb = writer.getDirectContent();
RandomAccessFileOrArray ra = null;
int comps = 0;
try {
ra = new RandomAccessFileOrArray(documentByteArray);
comps = TiffImage.getNumberOfPages(ra);
} catch (Throwable e) {
_log.error(e.getMessage());
return null;
}
for (int c = 0; c < comps; ++c) {
try {
Image img = TiffImage.getTiffImage(ra, c + 1);
if (img != null) {
System.out.println("page " + (c + 1));
if (img.getScaledWidth() > 500 ||
img.getScaledHeight() > 700) {
img.scaleToFit(500, 700);
}
img.setAbsolutePosition(20, 20);
//document.add(new Paragraph(tiff_file.getName() +
" - page " + (c + 1)));
cb.addImage(img);
document.newPage();
++pages;
}
}catch (Throwable e) {
_log.error(e.getMessage());
return null;
}
}
ra.close();
document.close();
byte[] result = output.toByteArray();
return result;
} catch (Throwable e) {
_log.error(e.getMessage());
return null;
}
}
