#OR use this one.
#If you screenshot individual windows, the alpha channel prevents Tesseract from scanning properly. Also a lot of UI text is too small to accurately scan. To solve this I preprocessed with ImageMagick like so:
#CONTENTS=$(convert "$1" -magnify -alpha remove - | tesseract -c language_model_penalty_non_dict_word=0.8 --tessdata-dir /usr/local/share/ stdin stdout -l eng | xml esc)
#Testing with a screenshot of my Terminal, I got better results with -magnify than -adaptive-resize '200%x200%', but YMMV.
