[anvpn]

Hi wysaid

I hope you are doing well , Again i need your expertise help

I have requirement of set brightness,contrast,saturation as user want , i want to customize the filter as user want

I will give three slider where user can set the slider value and filter reflect according that

I have tried by following way

float currentBrightness = [sender value] ;//* 3.0f - 1.0f; //[-1, 2]

const char* config = "@adjust brightness ";

NSString *configDate = [NSString stringWithUTF8String:config];
 configDate =  [configDate stringByAppendingString:[NSString stringWithFormat:@"%.2f",currentBrightness]];
config = [configDate UTF8String];

NSLog(@"brightness effect %s--------",config);

[_myCameraViewHandler setFilterWithConfig:config];

Same for saturation and contrast but when i set brightness it works perfect but when apply saturation it wont work

Please suggest me how can i achieve this
