gohocr

gohocr parses Tesseract's *.hocr files to structs. It can be used as a library as well as from the command line.

Getting Started

Install

go get github.com/stefanhengl/gohocr

Use as Library

import (
    "github.com/stefanhengl/gohocr
)

func main() {
    page, err := gohocr.Parse("path/to/hocr/file.hocr")
}

The hOCR can either be provided as string (path to a hOCR file), as *os.File or []byte. All of the following calls are equivalent

page, err := gohocr.Parse("path/to/hocr/file.hocr")
page, err := gohocr.Parse(os.File)
page, err := gohocr.Parse([]byte)

page is a struct which can be marshalled into json

pageJSON, err := json.Marshal(page)
if err != nil {
    log.Fatal(err)
}
ioutil.WriteFile("page.json", pageJSON, 0644)

Command Line Interface

The CLI will create a json in the same folder as the input file.

go install github.com/stefanhengl/gohocr/..
ghocr -f /path/to/hocr/file.hocr
