tess_lstm_box(
    inst::TessInst,
    page::Integer = Int32(1)
)::Union{String, Nothing}

Return the UTF-8 box file for LSTM training. If there is an error 'nothing' is returned.

Arguments:

T	Name	Default	Description
R	inst		The Tesseract instance to call.
O	page	`Int32(1)`	The page to get the data for.

Details:

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

Example:

using Tesseract

download_languages()

instance = TessInst()
pix = sample_pix()

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

box = tess_lstm_box(instance)

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