get_gold: Extract text from a PDF with embedded text.

In jacob-ogre/ocrerrors: Find Optical Character Recognition Errors and Corrections

Description

Uses pdftools::pdf_text to get the text layer from PDF 'file', which is used as the 'gold standard' against which OCR'd versions are compared. Checks that the text layer is distilled from the original document rather than a text layer from OCR, e.g., a scanner that OCRs.

Usage

get_gold(file, write = FALSE, save = TRUE)

Arguments

file	Path to the PDF to be processed
write	Whether to write the text to file [FALSE]
save	Whether to save the text as a .rda [TRUE]

Value

List of pages with text layer if layer not from OCR; else NULL

Examples

# res <- get_gold("test.pdf", "GOLDs")
