Need to call text2image unique "--fontconfig_tmpdir" when multi-threaded #298

Closed james-evy closed 2 years ago

In generate_font_image(), in tesstrain_utils.py; You need to create a unique folder name to pass text2image as the fontconfig_tmpdir parameter. I check the code or text2image. It will rewrite the files in the passed directory, creating a race condition.
Unless text2image is modified to handle a "--keep_tmpdir_if_exists" like flag is added, this will be an issue. patch.txt
