Question
I would like to add some custom data to an image the user generates in my app, no more than 1kb tops. I could probably hide the data in the image, but I want to do this in a way that will resist resizing but not deliberate deletion of EXIF tags (say, for privacy reasons).
Is this possible using the current public SDK 3.0?
Solution
this might be helpful, though i've never used it before - iphone-exif
OTHER TIPS
This could be very useful: PhotoshopFramework is one powerful library to manipulate images on Objective-C. This was developed to bring the same functionalities that Adobe Photoshop users are familiar. Examples: Set colors using RGB 0-255, apply blend filers, transformations...
Is open source, here is the project link: https://sourceforge.net/projects/photoshopframew/
