I want to know two things please:

I would like to resize an image in Jetpack Compose but I get an error:
Unresolved reference: size

What am I supposed to import because I imported this

import androidx.compose.ui.Modifier

Where can I see what can be imported because this is surely the biggest headache knowing what to import.

Also how do I use the colors I specify in my colors.xml file located in the res directory.

I want to use the colors I have in my resource file called colors.xml

Here is my composable trying to set an image size and a button I want to give a background color to:

@Composable
fun Logo(modifier: Modifier = Modifier) {
    Image(
        painter = painterResource(id = R.drawable.slipsol),
        contentDescription = "The SlipSol logo",
        modifier = Modifier.size(80.dp),
        contentScale = ContentScale.Crop
    )
}

@Composable
fun FrontButtons() {
    Column {
        Logo()

        Button(
            onClick = {},
            modifier = Modifier.width(200.dp),
            shape = RoundedCornerShape(4.dp),
            colors = ButtonDefaults.buttonColors(containerColor = Color.Green)
        ) {
            Text("See Promotions")
        }
    }
}

Help is appreciated thanks
