How to combine two images into one image object?
How do I combine two images?
I mean I have two images, one small and the other large. I want to add a small image to a large one at a certain point and I need to get it UIImage
as a result.
I've tried CGCreateImageFromMask
but this makes the small image completely covered by the large image.
You want to use UIGraphicsBeginImageContext()
to create CGContextRef
, then use UIGraphicsGetCurrentContext()
to get a link to it.
Now draw the current images in context. When you're done, use UIGraphicsGetImageFromCurrentContext()
to create UIImage
from this context and UIGraphicsEndImageContext()
to clean up.
See Apple UIKit Function Reference .
