okToExtractText
Check to see if the PDF file allows text extraction.
[read-only property]
okToExtractText([out, retval] VARIANT_BOOL *ok)
This function returns false if the PDF file is encrypted and does not
allow extraction of text. The owner password can be used to circumvent
this: if a valid owner password was supplied to
loadFileWithPassword
or loadStreamWithPassword
, this function
will always return true.
If this function returns false, the text extraction functions will not return any text.
VB:
If Not pdf.okToExtractText Then
' can't extract text from this document
...
End If
