Details:

This method will call tess_recognize() if it has not been called yet for the image.

This method is more used to test the OCR results than anything else. If you want the original Latin1 encoding use tess_unlv_latin1 method.

Example:

using Tesseract

download_languages()

instance = TessInst()
pix = sample_pix()

tess_image(instance, pix)
tess_resolution(instance, 72)

unlv = tess_unlv(instance)

for line in split(unlv, '\n'; keepempty = false)[1:5]
    println(line)
end

# output
