Hi,
I try to generate a pdf form with a barcode and precompleted field.
I can't have precompleted field and a barcode to a same form.
I'd define a button area and retrieve the positions like this:
float[] barcodebutton = form.getFieldPositions("barcode");
Rectangle rect = new Rectangle(barcodebutton[1], barcodebutton[2],
barcodebutton[3], barcodebutton[4]);
PdfContentByte cb = stamper.getOverContent((int)photograph[0]);
Note that index 0 gives you a page number;
index 1, 2, 3 and 4 give you the coordinates.
I would create my barcode as an Image, for instance:
BarcodeEAN codeEAN = new BarcodeEAN();
codeEAN.setCodeType(Barcode.EAN13);
codeEAN.setCode("9780201615883");
Image imageEAN = codeEAN.createImageWithBarcode(cb, null, null);
Then I'd resize and position my barcode:
codeEAN.scaleToFit(rect.width(), rect.height());
codeEAN.setAbsolutePosition(barcodebutton[1] + (rect.width() -
codeEAN.scaledWidth()) / 2,
barcodebutton[2] + (rect.height() - codeEAN.scaledHeight()) / 2);
Now you are ready to add the image.
cb.addImage(codeEAN);
C'est simple comme bonjour ;-)
br,
Bruno
