# Objective
In Bevy main, the unconstrained size of an `ImageBundle` or
`AtlasImageBundle` UI node is based solely on the size of its texture
and doesn't change with window scale factor or `UiScale`.
## Solution
* The size field of each `ImageMeasure` should be multiplied by the
current combined scale factor.
* Each `ImageMeasure` should be updated when the combined scale factor
is changed.
## Example:
```rust
use bevy::prelude::*;
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.insert_resource(UiScale { scale: 1.5 })
.add_systems(Startup, setup)
.run();
}
fn setup(mut commands: Commands, asset_server: Res<AssetServer>) {
commands.spawn(Camera2dBundle::default());
commands.spawn(NodeBundle {
style: Style {
// The size of the "bevy_logo_dark.png" texture is 520x130 pixels
width: Val::Px(520.),
height: Val::Px(130.),
..Default::default()
},
background_color: Color::RED.into(),
..Default::default()
});
commands
.spawn(ImageBundle {
style: Style {
position_type: PositionType::Absolute,
..Default::default()
},
image: UiImage::new(asset_server.load("bevy_logo_dark.png")),
..Default::default()
});
}
```
The red node is given a size with the same dimensions as the texture. So
we would expect the texture to fill the node exactly.
* Result with Bevy main branch
