## Using One Language

## Using Multiple Languages
tesseract --tessdata-dir /usr/share ./testing/eurotext.tif ./testing/eurotext-engdeu -l eng+deu
The output can be different based on the order of languages, so -l eng+deu can give different result than -l deu+eng.
## Using different Page Segmentation Modes
