After filing https://github.com/JetBrains/compose-jb/issues/108 I took a look at the implementation of

ImageAsset

as

AndroidImageAsset

and how it's painted in

AndroidCanvas.drawImage

- where it is explicitly checked to be an

AndroidImageAsset

. So even though

Canvas.drawImage

accepts

ImageAsset

, it's going to accept a very specific implementation of that interface - one on Android and one on desktop. Is there a way to create an

ImageAsset

at runtime dynamically? Not from a resource, not from a file, but by populating each pixel individually as an int array, and then "wrapping" that array as an implementation of

ImageAsset

that is platform agnostic?

ImageAsset is an interface with expect/actual function constructors for desktop and android. The ImageAsset created from non platform specific code will create a desktop ImageAsset and when drawing it will draw into the desktop based canvas which checks to see if it is an instance of Desktop ImageAsset. The android canvas implementation checks that the instance is of AndroidImageAsset. A platform implementation of compose isn't complete without having each of the mpp facilities implemented

I understand this, but my issue is not being able to convert an array of pixels (as integers) to an image asset.
