pub fn new(
ui: &'a mut UiCell<'b>,
size: (u32, u32),
parent: Id,
font: Id,
graph: &'a mut ConrodBackendReusableGraph
) -> Self
Create a new Conrod backend drawer, with:
ui
: theUiCell
that was derived fromUi
for this frame(plot_width, plot_height)
: the size of your plot in pixels (make sure it matches its parent canvas size)ids.parent
: thewidget::Id
of the canvas that contains your plot (of the same size than the plot itself)fonts.regular
: thefont::Id
of the font to use to draw text (ie. a Conrod font identifier)conrod_graph
: a mutable reference to the graph instance you built outside of the drawing loop (pass it as a mutable reference)

§type ErrorType = ConrodBackendError
type ErrorType = ConrodBackendError
The error type reported by the backend
source§fn ensure_prepared(
&mut self
) -> Result<(), DrawingErrorKind<ConrodBackendError>>
fn ensure_prepared(
&mut self
) -> Result<(), DrawingErrorKind<ConrodBackendError>>
Ensure the backend is ready to draw
source§fn present(&mut self) -> Result<(), DrawingErrorKind<ConrodBackendError>>
fn present(&mut self) -> Result<(), DrawingErrorKind<ConrodBackendError>>
Finalize the drawing step and present all the changes.
This is used as the real-time rendering support.
The backend may implement in the following way, when
ensure_prepared
is called
it checks if it needs a fresh buffer and present
is called rendering all the
pending changes on the screen.source§fn draw_pixel(

&self,
text: &str,
style: &S
) -> Result<(u32, u32), DrawingErrorKind<Self::ErrorType>>
Estimate the size of the horizontal text if rendered on this backend.
This is important because some of the backend may not have font ability.
Thus this allows those backend reports proper value rather than ask the
font rasterizer for that. Read more
