PDF Server
Upload PDFs to the Flask server and request specific pages from it through a form or URL
Page Range Formats
Page ranges are structured in a way similar to printing ranges.
Use a comma-separated list of numbers of number ranges like 1,3,4-9,11 to choose the pages on the pdf to extract.
In the example, pages 1, 3, 4, 5, 6, 7, 8, 9, 11 will be extracted.
There is also a shorthand for "Until the last page". Using 1,10- for example would return pages 1, 10, 11, 12 and so on until the last page of the selected pdf.
Invalid page numbers will be ignored.
URL Endpoints
/: The main page. Contains a form that acts as a GUI for selecting PDFs and their page numbers and is the only way to upload your own pdfs/view/<file_name>: Allows user to view a result page. Does not allow viewing the original pdf/download/<file_name>: The same as/viewexcept it automatically downloads the file onto the user's downloads folder/redirect/<file_name>/<page_range>: An endpoint that allows a user to generate a pdf from a pre-existing source without using the form. Used as a sharable link
