Convert base64 text to images/gifs

[greenart7c3]

fixes #951

[greenart7c3]

It still freezes the app if i press the show more button. Should I try to change the text note to make it convert the base64 to a image?

I think we will have to :(

You can also use the Base64 Requester which I think does the decoding in an IO thread.

            val context = LocalContext.current
            val base64Painter =
                rememberAsyncImagePainter(
                    model = Base64Requester.imageRequest(context, model),
                )

            Image(
                painter = base64Painter,
                contentDescription = contentDescription,
                modifier = modifier,
                alignment = alignment,
                contentScale = contentScale,
                colorFilter = colorFilter,
            )

Using this makes base64 gifs not work

Please @greenart7c3 can you try this solution?(It's a slight modification of @vitorpamplona 's suggestion. Needs Coil's gif library extension, see here.
Edit: moved LocalContext call to the top, for correctness.

val context = LocalContext.current
val gifImageLoader = ImageLoader.Builder(context)
    .components {
        if (SDK_INT >= 28) {
            add(ImageDecoderDecoder.Factory())
        } else {
            add(GifDecoder.Factory())
        }
    }
    .build()

val base64Painter =
    rememberAsyncImagePainter(
      model = Base64Requester.imageRequest(context, model),
      imageLoader = gifImageLoader
    )

Image(
    painter = base64Painter,
    contentDescription = contentDescription,
    modifier = modifier,
    alignment = alignment,
    contentScale = contentScale,
    colorFilter = colorFilter,
)

Thanks, I'll test this tomorrow morning

Gifs doesn't animate when I use this solution

Thanks for the feedback. I guess the problem is at the level of Coil then.

Trying this pull request. How is this functionality invoked from the app please?

Edit: never mind, found the associated bug!

[davotoula]

Very slow scrolling of home feed on first try. Is this a known issue or just cache priming?

[greenart7c3]

I'll look at this later. Have you tried creating a release build to see if it's slow too?

[davotoula]

It was a debug build... And trying other branches with a debug build it's similarly slow.

So I suspect it's the debug build rather than your PR 👍

[vitorpamplona]

Yeah, debug will always be extremely slow due to the added tracking points for debug.

Use the "benchmark" build variant to see real speeds.

[davotoula]

Good point, thanks!
