Task is write a c# pgm that runs at command line and accepts pdf file as well as textfile.
Textfile contains certain lines with words and positioning information as well as length information.
This text must be put to the pdf with a "invisible" color. Goal is to have a PDF where text is invisible there, but that can marked by drag with mouse.
The font should be determined by the give string size.
Process should not significant raise the size of input PDF file.
Programm should be able to replace input PDF.
we can make use of iTextSharp for creating hidden texts (shown upon selection made using mouse) in a pdf file. Let me know your availability to discuss further. Thanks.
