This installation guide is tested with Nextcloud 11 and Ubuntu 16.04 x64.
Nextcloud OCR (optical character recoginition) processing for images and PDF brings OCR capability to your Nextcloud server. Currently there are more than 100 languages supported.
- in case of a PDF a copy will be saved with an extra layer of the processed text, so that you are able to search in it.
- in case of an image (PNG, JPG, TIFF) the result of the OCR processing will be saved in a .txt file next to the image (same folder).
