CGPathRef defines an opaque type that represents an immutable graphics path. CGMutablePathRef defines an opaque type that represents a mutable graphics path.
But how do we change the opacity in the CGPath
in CoreGraphics
? Can it be addd in percentage?
It's called "alpha" in UIKit and Core Graphics. For example:
UIColor *color = [[UIColor alloc] initWithWhite:0.5f alpha:0.5f];
CGContextSetStrokeColor(context, color.CGColor); // Assuming you have a context.
CGContextStrokePath(context);
