I want to make a multi-device software with godot engine and I want to make it as lite as I can, so I just want to use a Line edit node and a button for saving the text but, is there any way to save it as .txt and .pdf files with code or I need an extra plugin?
Writing a plain text file is relatively easy:
var file = File.new()
file.open("user://some_file.txt", File.WRITE)
file.store_string("Some text")
file.close()
PDF is more difficult. I don't think that there are any out of the box solutions. But remember that PDF is also just a text file with specific commands embedded into the text. You would have to study the specifications of a PDF file and then generate the required structures yourself via the method described above.

I would like to read a PDF file as a text (postscript), add new objects in the file structure and save the final output as a new PDF but If I just copied the PDF PostScript content and paste it in a newly created PDF file (where encoding='ansi'), the file doesn't work.
I am sure that this may be encoding issue but I am not sure what I should do to have a valid PDF file format after manipulating the original PostScript content.
Here is the piece of code that didn't work with me:
pdf_file = open('Input.pdf', 'r', encoding='ansi').read()
pdf_file_bytes = bytearray(pdf_file, 'ansi')
pdf_file = open('Output_bytes.pdf', 'wb').write(pdf_file_bytes)
And as I said, the output PDF is not valid!
First problem; the content of a PDF file is PDF, not PostScript.
Secondly, PDF is a binary file foramt so if you copy and paste it any kind of translation (such as CR/LF) will break it.
You haven't said what programming language your code uses, though it looks like Python. If it is Python then reading the file as binary instead of text might help.
A PDF file is a complex file format consisting of various objects, unless you under low-level syntax of the PDF specification carefully it will be difficult to impossible to arbitrarily replace some bytes with some other bytes and have it result in a still valid PDF file.
More to the point what are you trying to accomplish. E.g. there may be a high-level way of doing whatever you're trying to do that doesn't involve manipulating PDF syntax directly. E.g. if you need to modify a font, add an annotation, set the PDF version, etc. Otherwise if you actually need to modify PDF syntax you need to use a library capable of dealing with low-level objects.
I am looking for the method (of Word ole-object) which can open pdf in the Microsoft Word.
I want to copy all pages of pdf into doc/docx and add there footers.
Could anybody give the cue how to import pdf?
PS: any sample code for this problem would be great.
Thanks,

You need OCR (Optical Character Recognition) engine for converting PDF to document. PDF is generic format and it can include text as image. So it is very hard to convert PDF to document. SAP hasn't got any OCR function for doing this. Maybe OpenText (if customer using it) has this functionality, I haven't got detail information about opentext. You need third party tools for this. You can use online services or command line utilities to converting PDF files to text files easelly if PDF included text, otherwise you need professional SDKs (for example Abbyy Finereader) for doing this.
I used FoxIT PDF Reader to save the PDF file into text file and make a macro to read the text file. Of course, by doing so, you can only get the text, but nothing else.
I am looking to create and save either a rtf, doc or docx file on an iPad (iOS).
The scenario is that we'd like to assist a user in creating content on their iPad and then let them email this as an editable document cross-platform (OS X, WIN).
I am open to other solutions besides the rtf, doc or docx file format.
Thanks,

RTF is going to be the easiest, because it's a plain text format. It's kind of like HTML, but without closing tags. Here is a class for writing an RTF, but it requires a lot of dependencies from elsewhere in the framework.
DOCX would be rather difficult. It's actually a zip file, containing a few XML files. You can examine the format yourself by changing the .docx extension to .zip and unzipping it. But even though XML is a fairly easy to write format, the way the text attributes are organized is still rather complicated. Also, I recall that it has to be zipped in a very specific way to be read properly.
As for DOC, it will be very difficult because it's such a complex format. You could look into some open source projects, like Abiword or Word2x. Be careful using their code because the licenses may not agree with the App Store rules.
I've seen doc & docx readers for iPhone (App store entry linked here), but I don't know of any open source frameworks you can make use of.
RTF format should be pretty simple to write, if you're up to the challenge. There is no built in framework support for it (here's a related question, b.t.w.).
Maybe you could write out something in a regular TEXT format and e-mail that?
Docmosis has a cloud service that you can reach from iOS. You can ask it to render a doc in various formats (doc, rtf, pdf, odt etc) and email it off or stream it back - though you have to be connected. Previewing DOC on iOS is possible but a little flaky. One option is to stream PDF back for display on iOS and email editable document (which can be done in one call).
I'm creating PDFs using Texmaker. I would like to create some of the PDF files so that when I give the PDF to others, they are not able to print the file or to copy the text. I know I can do this with some PDF creator applications, but can I do that from some command like program I have with Latex, MikTex and TexMaker?
It wouldn't be effective anyway. There are bits in the pdf format that purport to forbid the user from doing this, but they are really just suggestions that the reader application may or may not act on. There is nothing to stop a user from removing the code that inspects the bits from a free/libre PDF reader, or just to run a tool over the file to remove the restrictions.
I'm currently using a combination of OpenOffice macros and a pdf2text program to extract text and would like to find an easier, more efficient way getting the text out of a PowerPoint file.
I've tried using the Apache POI library and have not had much luck, encountered numerous exceptions within the library when trying to process the files I'm looking at and don't particularly want to sift through the source code of the library.
Is there an easy way to do this without using the aforementioned library?
If you have MS Office and you save the PPT in the RTF (Rich Text Format), it contains just the text from the presentation. You could then open the file in any editor that understands RTF files and save it as a text (TXT) file.
I expect this to work from Open Office too.
Since you talk of API, this may not be the way to go for you but maybe it will give you newer ideas on getting there. Say, you use multiple macros to do the conversion in stages...
Edit: I got curious and did a short google search
This is what i found on one of the www.openoffice.org pages
As people in this thread have pointed out, retrieving text from an OO
document isn't hard since it's just zipped xml that can be parsed with a
perl script. The problem is getting Microsoft Powerpoint documents into
a zipped XML format in the first place.
I've found that File -> Wizards -> Document Convertor does exactly that.
Just tell it you want to convert Powerpoint documents, not templates,
point it to your source directory and where you want it to spit out the
result and you're away.
I then find unzip -p $file.sxi content.xml | perl -p -e
"s/<[^>]>/\n/g;s/ +//;s/\n\n/\n/g;" -w
works rather well for extracting the text.
Sorry, i don't have Open Office handy to try any of that out.
pptx files are relatively easy to deal with, because they are just zipped xml - you can just unzip them and then strip all the xml tags from the content of the files in the 'ppt/slides' subdirectory of the unzipped stuff, yielding most of the pertinent text.
ppt files are a whole other ballgame, and the process is rendered even more painful because the canonical tool, catppt from the catdoc package, is susceptible to a buffer overflow that makes it nearly useless (it segfaults on a large percentage of ppt files).
LibreOffice-5 File - Export - HTML includes both slide contents and presenter notes.
Then, open the .html file in Firefox or other browser, and File - Save Page As - Text File (or utility such as pandoc -o file.txt file.html).
