Hi !

Thank you !
It could be useful in the future..

However browsing the forum here and by google...I've found this code for tint / colorize a gray scale image...it work fine!!

+ (UIImage *)colorizeImage:(UIImage *)baseImage color:(UIColor *)theColor {
    UIGraphicsBeginImageContext(baseImage.size);
    
    CGContextRef ctx = UIGraphicsGetCurrentContext();
    CGRect area = CGRectMake(0, 0, baseImage.size.width, baseImage.size.height);
    
    CGContextScaleCTM(ctx, 1, -1);
    CGContextTranslateCTM(ctx, 0, -area.size.height);
    
    CGContextSaveGState(ctx);
    CGContextClipToMask(ctx, area, baseImage.CGImage);
    
    [theColor set];
    CGContextFillRect(ctx, area);
 
    CGContextRestoreGState(ctx);
    
    CGContextSetBlendMode(ctx, kCGBlendModeMultiply);
    
    CGContextDrawImage(ctx, area, baseImage.CGImage);
 
    UIImage *newImage = UIGraphicsGetImageFromCurrentImageContext();
    
    UIGraphicsEndImageContext();
    
    return newImage;
}
