Pdf to text command line12/16/2023 ![]() are updated throughout the whole document, in just a few moments. Then click “Replace”, and a recurring typo, wrong name or date, outdated data, etc. Now, in the “Replace” tab, you can type in the text to be replaced, view the search results and select in which places exactly you want the text replacement to be done. In “Find” and “Redact” you can search & highlight and search & redact, which are operations that already existed before this update. There are three tabs now in the Search tool: “Find”, “Replace” and “Redact”. – either altogether or just change the entries you select. The redesigned Search tool in the PDF Editor provides you with a new useful capability – you can search for a keyword or a key phrase and replace it to another specified text throughout the whole document, including comments, metadata, etc. If you want the possibility to change a word or a phrase at once over multiple places in a document, if your organization uses a DMS or ERP that you would like to integrate document conversion or comparison into, or if you are going to operate FineReader PDF with an RPA system – you definitely need to check out the new Release 7 capabilities! 1. However, it will not work in the general case.A new FineReader PDF 15 Release is ready for our users. WARNING: The answer currently marked as 'accepted' might have worked for the specific PDF of the OP. you use a text editor to modify its contents after uncompressing the PDF source code. you are prepared to analyse the PDF file in question individually you are a PDF expert who is skilled to read the PDF source code No, there is no command line way to reliably remove unwanted strings from a PDF! You can only find out by opening its source code in an editor and analysing its content. Remember, you do not know the encoding in advance, nor the placement correction numbers, when you deal with an arbitrary PDF. Now you show me how you'd replace that "string" by something else by using sed. The numbers in between these hex snippets ( 29, -2, 6 and -1) are correction values which determine the individual spacings of the different characters. ![]() The meaning of the hex snippets enclosed by angle brackets are the following, according to the 'charmap' table specific for that PDF and the used font: TJ: TJ is an operator to show text while at the same time allowing for individual glyph positioning. F2 16 Tf: Tf is an operator to set a certain font as well as its size as the currently active one in this case it is the font tagged elsewhere with the name /F2 and its size should be 16 pt. ![]() Here is an example for the "string" Watermark, how it can appear inside a PDF created with LibreOffice: 56.8 726.989 Td /F2 16 TfTJĥ6.8 726.989 Td: Td is an operator to move the text positioning on the page 56.8 726.989 are the x-/y-coordinates to describe that exact position. Hence in all these cases your sed command will not succeed - not even after uncompressing the PDF. Instead it may be hex encoded.Īdditionally, an ASCII string's individual characters might be placed on the page in a consecutive order, but they may easily be placed individually, with each having its own coordinate information sprinkled in between the individual characters.Īlso, the hex encoding of the ASCII (and non-ASCII) character table (the "mapping") will not be predictable, and it may change from font to font. What appears to be ASCII text in the visual representation of its content in a PDF viewer, very likely will not be ASCII text inside the PDF source code. but this case I'll not discuss any further - below I deal only with real text contents in a PDF.) Reasons (Moreover, watermarks inserted by LibreOffice frequently are converted into vector or pixel graphics, even if they appear like text when printed or viewed on screen. It will not work for the general case of text replacement in PDFs (watermarks or not), and you'll have to be very lucky for very rare cases of PDFs you encounter were it would work. Sorry, the answer given by is as wrong as it could be as a general advice. Accepted answer will work only in rare cases
