Hi! Is there a way to get pixel color on

Canvas

by coordinates?

What is your use case? Generally it is quite slow to read pixels back from GPU memory. If you are working from source data like an image or other data derived from app state, it's better to get what you need from there instead of from final pixels.

Getting a pixel color would mean interrupting command recording, flushing the command buffer to the render thread then GPU, then wait for frame completion for readback, all the while blocking the main thread

I am implementing a recursive flood fill algorithm as part of a lab

You should do this on a

Canvas

that wraps a

Bitmap

then

Is there a way to convert Composables to Bitmap?

You can use a ComposeView to host your composables and draw that view into a Bitmap

Oh, I crashed with "width and height must be > 0"

Well how big is your Bitmap? 🙂

The problem has been resolved. 😀

Any updates will be posted on the bug
