how to use Sikuli in Java

How to adjust the screenshot of the similarity in Java

LOL, just used Google Translator to translate to English ;-)

String img = "some-image.png"; // the shot
Pattern pImg = new Pattern(ing).similar(0.95f);

or
Pattern pImg = new Pattern(ing).exact();

to request "exact" matching (wanted score >0.99)

Grrrr, the auto-correct has worked ;-)

String img = "some-image.png"; // the shot
Pattern pImg = new Pattern(img).similar(0.95f);

or
Pattern pImg = new Pattern(img).exact();

to request "exact" matching (wanted score >0.99)

and then you can use pImg instead of img in the respective methods like find, click, exists, ...
