How can I place an image over an existing PDF file at an specific coordinate location. The pdf represents a drawing sheet with one page. The image will be scaled. I'm checking ReportLab but can't find the answer. Thanks.
答
from pyPdf import PdfFileWriter, PdfFileReader
output = PdfFileWriter()
input1 = PdfFileReader(file("document1.pdf", "rb"))
watermark = PdfFileReader(file("watermark.pdf", "rb"))
input1.mergePage(watermark.getPage(0))
# finally, write "output" to document-output.pdf
outputStream = file("document-output.pdf", "wb")
output.write(input1)
outputStream.close()
我认为它类似于watermark，有关详细信息，请参见手册
I think it's like watermark, see the manual for better idea
