Sikuli not able to recognise images taken through Remote desktop and when run directly on system due to font antialiasing

There are two main ways to solve your problem:
1. Make both interfaces to use either antialiased or non-antialiased fonts. E.g. switch it OFF or ON both machines.
2. Reduce the factor of similarity, using standard Sikuli IDE instruments. So that your script could catch antialiased and non-antialiased screenshots of text.

The last way make your script less robust and so you should test all your images on both computers. For large text (let it be more then 10–15 pixels in height) the last way is suitable and for small text the first way may be the only suitable in your case.

Thanks Alex,

but can you please explain how can we use the first option suggested by you as we are able to disable cleartype setting of windows to used non-antialiased fonts but we are manually disabling it is there any way we can do it pragmatically.

Please suggest.

Could you manually disable antialiasing on the remote system? If yes, does that system keep this setting?

actually now we are running the script directly so we are able to disable the anitaliasing setting and yes system keep that setting but as it is being used by other people after running the scripts we have to revert the setting back. So if we can do this pragmatically that will resolve our issue

and Alex please let me know if I use Settings.similarity to reset the similarity factor I need to increase the value or decrease it I am very new to sikuli so I am asking these basic questions.

OK, there should be a way to run *.bat file to toggle ClearType on/off, look here: http://www.techsupportforum.com/forums/f10/solved-cleartype-command-does-it-exist-332657.html

Or you could try to "sikulify" the sequence of your mouse clicks to get antialiasing on/off to revert it back, that would be good exsercise for you. Yes, this is right setting, but keep in mind that this is global setting, and in my tasks I prefer set similarity for each image manually. Sometimes I need 99% similarity both with 50% etc.
