Has anyone accomplished the following in common code, or knows if it’s already possible with existing tooling?

Step 1) 🎨 Draw on Canvas
Step 2) 🧮 Convert Canvas to ByteArray
Step 3) ⬆️ Upload Byte Array with Ktor to server

Step 3 is of course possible already - I’m wondering on the converting Canvas content to ByteArray part

On Android it’s pretty straightforward . On iOS you need a small work around, you can either consider going the cinterop way and for the ByteArray conversion on iOS . Take a look at peekaboo multiplatform camera lib he has the work Around.

Hey @Dennis, are you specifically talking about transforming a Compose Canvas to Byte Array on iOS?

Do you want the bytearray to be an image?
Or just want an exported canvas file that can imported into another compose canvas??

Hey @Cherrio LLC, I want to let the user draw his signature on a Compose Canvas and then i want to upload this canvas (as ByteArray or so) to my server via Ktor. You know if that’s possible using ComposeCanvas?

[Cherrio LLC]

Yes it is
Check Qrose

Check how qrose uses the canvas

Ooh @Max I ment converting iOS image to byte Array, I was hoping it would provide you with more Context on how you would replicate the same
