I have searched for an answer to this question but perhaps I am searching with the incorrect terminology as I have found nothing so far. Any help would be great!
I would like to extract the positions of text fields, check boxes, radio buttons, list boxes, etc. from an Adobe PDF file. Is there a way to do this? Is there a way to do this with Python?
Thanks for your help!
Does this post help? It runs through extracting text from a pdf and has a line of code commented out which will show the coordinates of text. Finding and extracting specific text from URL PDF files, without downloading or writing (solution)

I am unable to save this as a searchable PDF for several words, e.g., the year (1964).
Can anyone assist?

This is caused by the use of Text Effects. The headline has a shadow and the subhead has a bevel. PowerPoint bitmaps those when it saves as a PDF. Here's my article on this problem: Text Effects? Don't! - Best Practices
When I make a PDF from your file (Windows PPT 365/64-bit under Win10, using File, Save As and choosing PDF as the Save As type) the text in question (Conrad 1964) becomes an image in the resulting PDF. I can't figure out why, but that would guarantee that the text isn't searchable ... it's not text.
If I delete the text box in question then re-create it, it becomes text when I save as PDF again.
It seems that something's gone mildly corrupt with that shape.
I have a visual basic program that extracts text from a PDF and imports the text into excel. It relies on reading the text like a human, reading left to right across the page. However, there are instances on this particular PDF where if I go to select the text with my mouse, I click and drag straight across but Adobe starts to select/highlight words on the above and below lines before continuing to highlight across the page. This gives me data that I do not want/need. The page has renderable text and is not from a scanned document.
Is there a way to "reset" the way Adobe interprets the text on the PDF? Since the information on the left is far from the information on the right, it treats them almost like separate columns.
I've tried saving the PDF in different formats such as a txt or postscript and distilling to another PDF but they all seem to result in the same outcome. This is weird to me because I have other similar PDFs where this isn't an issue.
Any help or thoughts would be greatly appreciated, thanks.
As PDF (in its basic form) essentially means placing strings on a canvas, the concept of "sentence" or "reading order" is not built in.
In order to extract text, you would have to read out the bounding box of the piece of text, and then use some logic and heuristics to assemble your text based on the coordinates of the bounding box.
Things can be easier if the PDF is a structured PDF, where the text contents is embedded as text in the document. This is also the prime requirement for an accessible document. So, if your document is accessible, you can rely on the structure for the correct reading order.
I have a project where I have to find the letters of my name in a given text file in VB2010 and return those letters using string manipulation techniques as my name into a label control.
I have looked at several youtube videos and looked around the web. Some recommend putting the text file into an array. Some others are just for one specific word (Which my name isn't in the text file as a word). So I really haven't found anything to suit my needs.
I know the code needs to placed in the event load form.
I've only been at VB for 7 weeks, so I am novice.
Any tips or hints are appreciated. If further explanation needed please let me know.
Thanks,
Well, we won't do your homework for you, but here's a HOWTO on reading a text file in VB.NET. It's a good starting point.
How to: Read Text from a File
Look up regular expressions. This should help you with the parsing of the text file.

right now i am working on one ipad application where i am giving facility of opening the pdf file and also to customize it,now i want to add one functionality like i want to convert that pdf file in .doc format.
I researched but did not get any way around. Can anybody help me out?
Thanking you in advance.
I wrote an article on PDF to text conversion issues. If you look at some of the existing PDF to Word conversion tools (ie BCL) you will see what is realistically possible with a lot of work.
It’s not possible to convert a generic PDF back into a text format. I guess you could render the PDF into images and create a DOC from those, but that doesn’t sound very useful.
