Implementation of 9-patch images in Bevy. Let you have a UI that scale only the right parts of your images.
See the examples for what can be done.
After adding the NinePatchPlugin plugin, spawning an Entity with the NinePatchComponents component bundle will add a 9-patch UI element.
A simple builder based on Godot's NinePatchRect is available.
```rust let paneltexturehandle = assetserver .loadsync(&mut textures, "assets/glassPanel_corners.png") .unwrap();
let ninepatchhandle = ninepatches.add(NinePatchBuilder::bymargins(20., 20., 20., 20., ()));
commands.spawn( NinePatchComponents { style: Style { margin: Rect::all(Val::Auto), justifycontent: JustifyContent::Center, alignitems: AlignItems::Center, ..Default::default() }, ninepatchdata: NinePatchData { ninepatch: ninepatchhandle, texture: paneltexturehandle, ..Default::default() }, ninepatch_size: NinePatchSize(Vec2::new(500., 300.)), ..Default::default() }, ); ```
See plugin.rs example for a complete example.
The component NinePatchSize can be changed to update the size of the 9-Patch UI element. Changing this component must happen during the UPDATE stage and may not work otherwise.
See change_size.rs example for a complete example.
You can specify the content to be used inside the 9-Patch UI element. When creating a 9-Patch by specifying the margins, a content zone will be available by default for the center of the 9-Patch UI element. This can be set with the NinePatchContent component.
See multi_content.rs example for a complete example.
It is possible to set any number of patches for an image, the only constraints is that all patches in a line must have the same height. Using this methods, different parts of the image can grow at different rates, and several content zones can be created.
See full.rs example for a complete example.
9-Patch UI elements can be added without using a plugin if needed. Without the plugin, 9-Path UI elements can still be created, but changing size won't work.
See nopluginsimple.rs example for a simple example, or the other examples without plugin.
