Most PDFs do not.īetter PDF creation and editing programs have OCR (Optical Character Recognition) that can be used to recreate the elements of the original document used to create the PDF with varying degrees of success.
To be able to do any editing other than markups, etc., the PDF has to have the original text, fonts, etc. PDFs are images of an original document (not JPEGs). Except for downloaded documents, such as receipts, I create most of my PDFs with LibreOffice Writer (permanently set to embed the original file in the PDF) or Qoppa's PDF Studio Pro. odt document to a hybrid PDF (post another thread if you need directions on how to do it). LibreOffice Writer has to be set to export a. odf file used to create the PDF embedded into the PDF. You can open a PDF in LibreOffice Writer only if the PDF was created with the. While you are correct, what you said is overly simplified.
Could you please try again and export it to this format : Hybrid PDF (includes ODF format). The cause may be that the exported PDF is not a Hybrid pdf. A lot of software just ignores it, but I don't know about Draw so if it is one of those PDFs you may have to unlock it somewhere else first.
I don't know how Draw interacts with PDFs that are edit-locked. The PDF is encrypted, but then the encryption key is left inside the document and the software that reads it is told "please only use this key to look at the PDF but don't let the user edit it". Edit locks are really just momy-medicine, so they aren't used much any more. Lastly, it may be that the PDF has an encryption key to prevent editing. You may have to select everything and ungroup it and keep doing that until you get down to the text elements. It may be real text but the text may be "grouped" in with other PDF elements that Draw interprets as groups. LibreOffice Draw can't select that as text either because it doesn't know how to turn those instructions back into letters. Instructions like "put your pen down, move it to the right one sixteenth of an inch, lift the pen, reposition it to the beginning of the last stroke, now move the pen down three sixteenths of an inch.". Which means they look like letters and but really they are a series of line and curve drawing instructions. Sometimes whatever software made the PDF converted the text to shapes. Some PDFs aren't images, but they also aren't exactly "text" either. In those cases, you can't select the "text" because there isn't any text in the PDF to select. They are JPEG images of the page embedded into a PDF page. There are many different ways text can be rendered inside a PDF and a lot of them just look like text but aren't really. It really depends on the PDF on whether what you are asking is possible.
