I m trying to convert a KorIM `Bitmap` to an `ImageBitmap` M

Question

I m trying to convert a KorIM `Bitmap` to an `ImageBitmap` My first brilliant idea was to write an implementation of `ImageBitmap` with a backing from KorIM That didn t work on Android or JVM because they both expect a specific backing Is there a way around this Failing that I guess I need to write a converter from KorIM to Skia for JVM JS For JVM I can use AWT as an interim format but I don t think JS has anything similar

My usage is something like ```val bitmap Bitmap32 = Image bitmap toComposeImageBitmap contentDescription = ``` where `toComposeImageBitmap ` creates an `ImageBitmap` backed by the Korim bitmap

Maybe I could write a painter for korim bitmaps instead

It really feels like `ImageBitmap` is a fake interface I m not sure where else it s used but not being able to use a custom implementation in `Image` means that there s not much reason for being able to implement it

I wrote a function to convert Korim to Skia bitmaps If anyone finds it useful ```import androidx compose ui graphics ImageBitmap import androidx compose ui graphics asComposeImageBitmap import com soywiz korim bitmap Bitmap import com soywiz korim bitmap Bitmap32 import org jetbrains skia ColorAlphaType import org jetbrains skia ColorInfo import org jetbrains skia ColorType import org jetbrains skia ImageInfo internal actual fun Bitmap toComposeImageBitmap ImageBitmap return toBMP32IfRequired toSkiaBitmap asComposeImageBitmap internal fun Bitmap32 toSkiaBitmap org jetbrains skia Bitmap val colorType = ColorType N32 val alphaType = if premultiplied ColorAlphaType PREMUL else ColorAlphaType OPAQUE val skiaColorSpace = null val colorInfo = ColorInfo colorType alphaType skiaColorSpace val imageInfo = ImageInfo colorInfo width height val bitmap = org jetbrains skia Bitmap val pixels = extractBytes bitmap allocPixels imageInfo bitmap installPixels pixels return bitmap ```
