Tesseract.tess_init — Function

tess_init(
    inst::TessInst,
    languages::AbstractString = "eng",
    dataPath::AbstractString = "tessdata"
)::Bool

Initialize the instance for the specified language(s). Returns false if there was an error.

Arguments:

T	Name	Default	Description
R	inst		The instance to initialize.
O	languages	`eng`	The language(s) to load.
O	dataPath	`tessdata`	The directory to look for the language files in.

Details:

This method can be called multiple times to reinitialize the langauges to OCR with. Multiple langagues can be specified by seperating them with a plus. So if you want english and spanish you could specify "eng+spa". The language codes are (usually) the ISO 639-3 code.

Note: The language files are NOT automatically downloaded. If you do not have them installed via alternate means you can download them from https://github.com/tesseract-ocr/tessdata_best.

Example:

julia> using Tesseract

julia> download_languages("eng+spa")
true

julia> instance = TessInst()
Allocated Tesseract instance.

julia> tess_init(instance, "spa")
true
