pdf_to_txt: Extract text from a pdf and write to a txt file

In jacob-ogre/pdftext: Extract Text from Text- and Image-based PDFs

Description

Extract text from a pdf, which may have a text layer that can be extracted with pdf_text; or which may be image-based and needs to be OCR'd with Tesseract. Both routes end with the extracted text written to a .txt file with form-feed (\f) metacharacters separating pages.

Usage

pdf_to_txt(file, thres = 0.2, verbose = TRUE, pre_ocr = TRUE,
  force = TRUE)

Arguments

file	Path to the PDF from which text will be extracted
thres	Threshold number of blank pages to be considered mixed [0.2]
verbose	Whether to print processing messages [TRUE]
pre_ocr	Use text layer if from previous OCR [TRUE]
force	Force text extraction even if TXT file exists [TRUE]

Details

Some PDFs include a mix of pages with and without an embedded text layer. Getting text from the text layer is preferable to OCR (most of the time), and to determine which approach to use,

Value

Nothing
