Details

hOCR is an open standard of data representation for formatted text obtained from optical character recognition. It can be used to generate searchable PDFs and many other things. This function generates a file compliant with the official hOCR specification (https://github.com/kba/hocr-spec) complete with token-level confidence scores. It also works with non-latin scripts and right-to-left languages.

Examples

if (FALSE) {
make_hocr(type = "async", output = "output.json")
resp <- dai_sync("file.pdf")
make_hocr(type = "sync", output = resp)
make_hocr(type = "sync", output = resp, outfile_name = "myfile.xml")
}
