Hello!

Im trying to find method to convert an image to some kind of text, so I can send it somewhere and "read" it later by convert back from text to image.

For exmaple, my last idea: I know that it's possible to "read" base64 encoded images in C3 by "Load image from" Sprite's method but I don't know if there's some method to encrypt image to base64.

What I want to do is to store image information in JSON file - and of course read it later in C3.

Can you help me?

There is an old C2 plugin, but I'm not sure if it can be ported to C3.

In C3 you can probably paste the sprite to DrawingCanvas, save canvas snapshot and then use some JS to convert it to Base64. Try googling "imagedata to base64 javascript", there are quite a few examples.

If the image is small and you don't necessarily need it to be in Base64, you can save snapshot pixel data in an array.
