can any tell me how to change brightness/contrast of an image in Blackberry?
I tried something but It doesn't work for me.
I have used a class and implement a interface called ImageTonalityControll.
It has methods like getContrast(),setContrast(int val),getBrightness(),setBrightness(int val), and more.
following is the code I use-
LoginSuccessScreen is my class. I have loaded one image in this class. But the there is no effect of changing Contrast on Image. Help me in this case..It will solve my other controls also. If U have your logic plz share....
private void changeImageContrast()
LoginSuccessScreen login=new LoginSuccessScreen(bp1);
login.setContrast(50);//set contrast value 50
contrast=login.getContrast();//reading contrast value to check the result
Dialog.inform(s1); //display the result on dialog
