RobotFramework: SikuliLibrary: Set Ocr Text Read, Get text keyword not working

I am working on windows app testing R&D for our windows project. I have run many test cases successfully. Now I need to check field value. Used 'Set Ocr Text Read' & 'Get Text' keywords. But RF doesn't get these sikuli keywords. But in keyword documentation of Sikuli these 2 keywords are mentioned. Sikuli Library is imported properly. Others Sikuli keywords are found except these 2.

Then I have installed 'SikuliXRobotLibrary' which is jython based. Installed it properly & run their demo project successfully. But while importing in RIDE, SikuliXRobotLibrary showing in red letter i.e. library is not imported. RF imports SikuliLibrary, why not SikuliXRobotLibrary? Need your kind help. Thanks in advance.
