Struct rsvg::aspect_ratio::AspectRatio

pub struct AspectRatio {
    defer: bool,
    align: Option<Align>,
}

Fields

defer: bool

align: Option<Align>

Implementations

impl AspectRatio

pub fn none() -> AspectRatio

Produces the equivalent of preserveAspectRatio="none".

pub fn is_slice(&self) -> bool

pub fn compute(&self, vbox: &ViewBox, viewport: &Rect) -> Rect

pub fn viewport_to_viewbox_transform( &self, vbox: Option<ViewBox>, viewport: &Rect ) -> Result<Option<ValidTransform>, InvalidTransform>

Computes the viewport to viewbox transformation.

Given a viewport, returns a transformation that will create a coordinate space inside it. The (vbox.x0, vbox.y0) will be mapped to the viewport’s upper-left corner, and the (vbox.x1, vbox.y1) will be mapped to the viewport’s lower-right corner.

If the vbox or viewport are empty, returns Ok(None). Per the SVG spec, either of those mean that the corresponding element should not be rendered.

If the vbox would create an invalid transform (say, a vbox with huge numbers that leads to a near-zero scaling transform), returns an Err(()).

Trait Implementations

impl Clone for AspectRatio

fn clone(&self) -> AspectRatio

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AspectRatio

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for AspectRatio

fn default() -> AspectRatio

Returns the “default value” for a type.

impl Parse for AspectRatio

fn parse<'i>(parser: &mut Parser<'i, '_>) -> Result<AspectRatio, ParseError<'i>>

Parses a value out of the parser.

fn parse_str(s: &str) -> Result<Self, ParseError<'_>>

Convenience function to parse a value out of a &str.

impl PartialEq for AspectRatio

fn eq(&self, other: &AspectRatio) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
