I’ve got more if you need to desaturate an image, remove all color, tint a
bitmap, as opposed to using tint, this actually makes a new tinted bitmap, find
imageInbundle, create enabled and disabled images from source images and so on.
Sometimes we want to use the actual tint, and other times, if
Thanks for the UIImage category resizing methods! They are quite useful.

Of course you’ll need to add checks to make sure that you’re not dividing by
zero or nil.

I’lll dig up a utility class that I made for UIImage that has this as well as

If you want serializable data bytes, sure, but thats not what you appear to be
doing
Okay. It was my understanding that -TIFFRepresentation was the only way to get
serializable image data bytes... What is a more efficient way to do this?

How can I correctly scale a UIImage from 3264x2448 down to 640x480 pixels?
I have an iOS app that interacts with a macOS server process. The iOS app takes
a 3264x2448 camera image, scales it to 640x480 pixels, and makes a JPEG
representation of it to send to the server:
