Hey folks! I have a multiplatform project that shares some business code between Android and iOS platforms. I have recently started migrating some views from android to compose multiplatform and have encountered this problem. One of the views used

ImageBitmap

to draw a png image on the canvas, and I can't find a method in mpp to create an object of this type from a resource. Any advice and help would be appreciated.

Did you have a look here: https://github.com/JetBrains/compose-multiplatform/tree/master/tutorials/Image_And_Icons_Manipulations ?

Yes, of course. There's an example with the java.io API, but I need a multi-platform solution that will work for Android and iOS at the same time. Do I understand correctly that out of the box there is no such solution and I need to use the expect/actual approach?

What exactly is your problem?

painter = painterResource("sample.png")

The above code gives you a painter and you can directly draw that into a

DrawScope

without having to use any platform dependent API.

My problem is that

DrawScope

allows to draw `ImageBitmap`s not `Painter`s returned from

painterResource

. I can't just create an instance of

Painter

and draw it on

Canvas

. The canvas API requires

ImageBitmap

. And I can't find a method in mp that can create that

ImageBitmap

from the file path like

imageBitmap("sample.png)

or so.

You can draw a painter directly onto a canvas. Here is the code.

import androidx.compose.foundation.Canvas
import androidx.compose.runtime.Composable
import androidx.compose.ui.Modifier
import androidx.compose.ui.res.painterResource

@Composable
fun TestPainterOnCanvas(modifier: Modifier = Modifier) {
    val painter = painterResource("image.png")
    Canvas(modifier) {
        with(painter) { draw(intrinsicSize) }
    }
}

Thanks @Michael Paus I'll give it a try
