<PDF document>: pdfDocument variable
Name of the pdfDocument variable to be used.
<Pages to extract>: Optional character string
Range of pages the text must be extracted form. The format used is identical to the one used in the standard printout boxes: individual page numbers of range of pages separated by semi-colons. For example, "1;3;4;6-10;12" means that pages 1, 3, 4, 6 to 10, and 12 will be processed.

Remarks

Conversion from PDF to text

  • The formatting of the document is lost when the conversion is performed from PDF to text.
  • The text is extracted in the order or appearance of the PDF commands and it is sequentially written into the result string. The organization of the text in paragraphs and in blocks is kept (as well as the CR characters).
  • The Unicode characters are not returned.
  • The data found in a PDF form is not extracted (this data is not stored in the PDF file).

Special cases

  • PDFIsProtected is used to find out whether a password is required to open a PDF file.
  • PDFNumberOfPages returns the total number of pages found in a PDF file.
  • Android From version 28, if the constant pttCompatible is not used, this function is not supported by 32-bit ARM processors. New PDF features require a 64-bit execution mode.
    If an application is to be run on devices with 32-bit ARM processors, it must be generated with WINDEV Mobile 27.
