pub struct Canvas<'a> {
    pub document: &'a Document,
    pub pictures: &'a mut Pictures,
    pub page: Rect,
    pub scale: f32,
    pub palette: Palette,
    pub edit_mode: bool,
    pub editor: Option<&'a mut Editor>,
    pub clicked: Option<Vec<usize>>,
    pub outcome: Option<Outcome>,
    /* private fields */
}

Fields

document: &'a Document

The document, for its styles and its pictures.

pictures: &'a mut Pictures

Pictures decoded so far.

page: Rect

The rectangle the page occupies on screen.

scale: f32

Screen points per ODF point.

palette: Palette

The colours to draw in where the document names none.

edit_mode: bool

Whether a click on a label’s paragraph opens it for editing.

editor: Option<&'a mut Editor>

The paragraph being edited, as a path from the page: the shape’s index among the page’s children, then the way down to the paragraph.

clicked: Option<Vec<usize>>

The paragraph a person clicked this frame in edit mode, as a path from the page.

outcome: Option<Outcome>

What the editor asked for this frame, if it closed.

Implementations

impl<'a> Canvas<'a>

pub fn new( document: &'a Document, pictures: &'a mut Pictures, page: Rect, scale: f32, palette: Palette, ) -> Self

A canvas over a page, drawing nothing editable until told otherwise.

pub fn slide_shape(&mut self, ui: &mut Ui, index: usize, shape: &Element)

One of the slide’s own shapes, by its index among the page’s children, which is what a label inside it is edited under.

impl Canvas<'_>

pub fn background(&mut self, ui: &Ui, fill: &Fill)

Fill the page.

pub fn shape(&mut self, ui: &mut Ui, shape: &Element)

One shape, at the place on the page the document puts it.

Drawn: draw:rect, draw:ellipse, draw:circle, draw:polygon, draw:polyline, draw:line, draw:custom-shape and draw:path — the last two have their outlines worked out by Geometry, from ODF’s own command language and from SVG’s respectively — a draw:frame holding a picture or a text box, draw:connector, whose route between the two shapes it joins the producer has already worked out, and draw:g, which is a group and is descended into. Left undrawn: draw:measure.
