Struct flo::standard_tools::Eraser

pub struct Eraser { /* fields omitted */ }

TODO: really, we should make the eraser subtract from existing paths rather than drawing over the top (this means when moving things around, any erasings stick around: also when something is entire erased it should be removed from the drawing).

We need to add path arithmetic at least before this is possible to do, however.

The Eraser tool (Erasers control points of existing objects)

Methods

impl Eraser

pub fn new() -> Eraser

Creates a new instance of the Eraser tool

Trait Implementations

impl<Anim: Animation + 'static> Tool<Anim> for Eraser

type ToolData = InkData

Represents data for the tool at a point in time (typically a snapshot of the model)

type Model = InkModel

The type of the model used by the UI elements of this tool

fn tool_name(&self) -> String

Retrieves the name of this tool

fn image_name(&self) -> String

Retrieves the name of the image that is associated with this tool

fn create_model(&self, _flo_model: Arc<FloModel<Anim>>) -> InkModel

Creates a new instance of the UI model for this tool

fn create_menu_controller(
    &self,
    _flo_model: Arc<FloModel<Anim>>,
    tool_model: &InkModel
) -> Option<Arc<Controller>>

Creates the menu controller for this tool (or None if this tool has no menu controller)
