I'm trying to make a Image Editing application on iOS where you have a Canvas which you can draw/insert graphics onto it, e.g you have a canvas (which is the same for all devices sizes, let's say 9:16) you insert an image, onto of that image you put a textbox with some text with font Times New Roman, with letter spacing of 3, font weight is bold, ect... My issue is figuring out how to save this 'graphic', for someone to continue to edit later.
Some thoughts I've had; Different screen sizes, means different pixel's w/h so it would have to be saved as a percentage based on the 16:9 aspect ratio. How would the text look the same on soo screen sizes, same dilemma? ratio based size.
I was unable to find any good resources to manage this, a similar behaviour I would want is like an Adobe Photoshop situation, where you can save the data and reload it to continue editing.
Would love some help.
