Load sprite from data (string or binary) not from path string ?

[tvortsa]

Hi!
I have deno.js as backend and deno.webview as GUI. I can load to my frontend any files (sprite image to).
Can i build a sprite not from path to file, but from already loaded (by deno) data of sprite file?

something like this way:

sprite_data = await deno.readFile(<path-to-my-sprite-file>) // here i can decode/encode any data as Base64 or anything else
const my_sprite = kaplay.loadSprite('mySprite', sprite_data) 

thank you!

if it is a base64-encoded png, you can load from a data URL like data:image/png,<base64>. As long as deno.webview can render a data URL that is probably the simplest solution.

Happy to hear it, thank you for your rapid ansver for me!
Im very inspired by KaPlay.js ^^
I working out sprite loading by deno file server started in web-worker. But i wish sprite loading by deno direct i will try it right now.
Thank you very much!

So its still not clearly for me, unfortunately.

I read dino.png by deno.readFile() as Uint8Array, should i convert Uint8Array to base64 ?
Can i give Uint8Array or base64 to KaPlay loadSprite() ?

Thank you!

The data URL must be base 64 encoded but deno.readFile gives you a uint8 array, sorry for the confusion... this page will probably help with the conversion

Thank you very much! its work for me now.

But i dont know how to do interaction between kaplay and webview.
I will try to work it out someways.

Well. I got it !
I cant use async code in binding functions of webview !
But if i use sync versions of deno file system metods - in this case all work for me!
Thank you very much again!
