I want to create a new irregular image from a image on iPhone
User will select the irregular shape from his finger and i want to create a new image from
that selected irregular shape
Any Idea how the user will select the irregular shape from image using his finger
Thanks in Advance for your valuable response
You could just draw the (filled with colour) shape / polygon the user created (by touching) in a UIImage, then use that shape as a mask as instructed here.
To allow the user to “select” his irregular shape, you just have to use
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event… the “touches” are the points you need for your polygon.
