Struct rsvg::Viewport

pub struct Viewport {
    pub dpi: Dpi,
    pub vbox: ViewBox,
    /* private fields */
}

Holds the size of the current viewport in the user’s coordinate system.

Fields

dpi: Dpi

vbox: ViewBox

Corners of the current coordinate space.

Implementations

impl Viewport

pub fn new(dpi: Dpi, view_box_width: f64, view_box_height: f64) -> Viewport

FIXME: this is just used in Handle::with_height_to_user(), and in length.rs’s test suite. Find a way to do this without involving a default identity transform.

pub fn with_units(&self, units: CoordUnits) -> Viewport

Creates a new viewport suitable for a certain kind of units.

For objectBoundingBox, CSS lengths which are in percentages refer to the size of the current viewport. Librsvg implements that by keeping the same current transformation matrix, and setting a viewport size of (1.0, 1.0).

For userSpaceOnUse, we just duplicate the current viewport, since that kind of units means to use the current coordinate system unchanged.

pub fn with_view_box(&self, width: f64, height: f64) -> Viewport

Returns a viewport with a new size for normalizing Length values.

Trait Implementations

impl Clone for Viewport

fn clone(&self) -> Viewport

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
