Hi there

I had a really strange idea on my pdf-files downloaded from several places.
My idea was to rename the files by information inside the file.
for that i found the tools of xpdfreader (especially pdftotext.exe, Link http://www.xpdfreader.com/pdftotext-man.html )
So far so good.
On console this tool is working like a charme.
commandline > pdftotext.exe -f 1 -l 1 test.pdf -

and on RunProgram there is only the Error: pdftotext version 4.02.
Nothing more.
To create an output text file is not the way I would like to go yet (only if no other solution is found:)
Maybe someone of you have some further hints?

Thanks in advance.

This works for me

Code: Select all

; pdftotext.exe and test.pdf are in c:\tmp

SetCurrentDirectory("c:\tmp")

RunProgram("pdftotext.exe", "-f 1 -l 1 test.pdf", "")

You can output text to console, so use it without file

Pdftotext converts Portable Document Format (PDF) files to plain text.
Pdftotext reads the PDF file, PDF-file, and writes a text file, text-file. If text-file is not specified, pdftotext converts file.pdf to file.txt. If text-file is ´-’, the text is sent to stdout.

Sample output to variable

Code: Select all

; pdftotext.exe and test.pdf are in c:\tmp

SetCurrentDirectory("c:\tmp")

Compiler = RunProgram("pdftotext.exe", "-f 1 -l 1 test.pdf -", "", #PB_Program_Open | #PB_Program_Read)
If Compiler
    While ProgramRunning(Compiler)
        If AvailableProgramOutput(Compiler)
            Output$ + ReadProgramString(Compiler) + Chr(13)
        EndIf
    Wend
    Output$ + Chr(13) + Chr(13)

    Debug Output$
    
    CloseProgram(Compiler) 
EndIf

Enjoy

Hi Marc56us
thanks for your feedback.
Then the problem is probably 40 cm in front of the monitor and between the ears.

As expected: My fault. Now here is a small tool that allows you to convert pdf texts completely or just the first page.
@marc56us: now i can update to the latest version. (I also saw it during my research.)
