I have a watermark that I would like to put into my pdf. The watermark is a .bmp image, and is 2290 x 3026. I am having a lot of trouble trying to resize this picture to fit the page, does anyone have any suggestions?
Document document = new Document();
PdfWriter.getInstance(document, new FileOutputStream("result.pdf"));
document.open();
document.add(new Paragraph("hello"));
document.close();
PdfReader reader = new PdfReader("result.pdf");
int number_of_pages = reader.getNumberOfPages();
PdfStamper pdfStamper = new PdfStamper(reader, new FileOutputStream("result_watermark.pdf"));
// Get the PdfContentByte type by pdfStamper.
Image watermark_image = Image.getInstance("abstract(0307).bmp");
int i = 0;
watermark_image.setAbsolutePosition(0, 0);
watermark_image.scaleToFit(826, 1100);
System.out.println(watermark_image.getScaledWidth());
System.out.println(watermark_image.getScaledHeight());
PdfContentByte add_watermark;
while (i < number_of_pages) {
i++;
add_watermark = pdfStamper.getUnderContent(i);
add_watermark.addImage(watermark_image);
}
pdfStamper.close();
Here is the output for the getScaled()
methods.
826.0 - Width
1091.4742 - Height
I would share the picture of the pdf with you guys but unfortunately I can't.
Should I try using a .jpg instead? I don't really know how well iText handles different image extensions.
I do it like that:
//if you would have a chapter indentation
int indentation = 0;
//whatever
Image image = coolPic;
float scaler = ((document.getPageSize().getWidth() - document.leftMargin()
- document.rightMargin() - indentation) / image.getWidth()) * 100;
image.scalePercent(scaler);
