Hi there, is there a way to convert Bitmap into ImageBitmap ? I would like to use the Image composable to display images that are stored locally. My idea was to use BitmapFactory.decodeFile(MY_FILE_PATH) to convert the images into Bitmap first and then from Bitmap to ImageBitmap

The way to handle it now is that you can use the Glide or Coil libraries to load them

CoilImage(Uri.fromFile(path...), null)

Amazing, thanks so much 🙂

if you already have an android Bitmap you can use the .asImageBitmap() extension: https://developer.android.com/reference/kotlin/androidx/compose/ui/graphics/package-summary#asimagebitmap

BitmapFactory.decodeByteArray(localByteArray, 0, locakByteArray.size).asImageBitmap()

and yo don't need anything else

but the reason to use something like coil or glide is to handle cache scoping; reloading and re-decoding the same bitmaps over and over will tank performance

ufff i see

[MBegemot]

that's why you put them in a hassmap

and then design a cache eviction policy, etc. 🙂

you can absolutely do it yourself, but tuning it is more work than it looks like at first.

@Adam Powell so you're not recommending the use of Coil or Glide ?

[Adam Powell]

I am recommending using them for their cache management. I am not recommending using them if you already have that problem space handled in some other way.

If you just want to convert Bitmap to ImageBitmap, use .asImageBitmap(), which is very easy. If you want to load a Bitmap and use it with Coil's or Gilde's many out-of-the-box features, you can use accompanist, otherwise you can simply use .asImageBitmap(), and apply it to an Image.
