Question #211334 on Sikuli changed:
https://answers.launchpad.net/sikuli/+question/211334
Status: Open => Answered
RaiMan proposed the following answer:
both ImageMagick (convert: work on images) and Tesseract (tesseract: get
text from an image) have commands, that can be used on the command line
and taking files as input and giving files as output.
So principally a shell script
convert input.png ... some actions output.tiff //* optimize for OCR
tesseract output.tiff ... additional options
would create a textfile in the end containing what Tesseract could read.
This shellscript can be run from a Java program, that produces input.png
using Sikuli features and finally reads output.txt to get the textual
result.
At least the first step (convert) can be done in memory using JMagick
and BufferedImages (which you can get from Sikuli too).
