I'm using the following code to draw a text over PDF page.Everything works fine, but if you process a PDF with internal links eg: a Book with Content links to pages, the resultant PDF file seems to have the links stripped off.Why does this happen?
let data = NSMutableData()
let consumer = CGDataConsumer(data: data as CFMutableData)!
let context = CGContext(consumer: consumer, mediaBox: nil, nil)!
let pdffile=PDFDocument(url: input)
for y in stride(from: 0, to: pagecount, by: 1)
{
let page: PDFPage = pdffile!.page(at: y)!
var mediaBox = page.bounds(for: PDFDisplayBox.mediaBox)
NSGraphicsContext.current = NSGraphicsContext(cgContext: context, flipped: false)
let bounds = page.bounds(for: PDFDisplayBox.mediaBox)
let size = bounds.size
page.draw(with: .mediaBox, to: context)
text.draw(in:drawrect,withAttributes:textFontAttributes);
context.endPDFPage()
}
context.closePDF()
try! data!.write(to: GetOutputFileName(inputfile: x), options[.atomicWrite])
