Struct Geometry

pub struct Geometry { /* private fields */ }

A rectangle slice of something, usually a large document image.

Units are a percentage of the containing document. This is more useful than pixels because we can more easily compare geometries between images of different resolutions. For example, we could identify all items in any bottom-right corner with Geometry(90%, 90%, 100%, 100%). Physical units would be better, but IIIF only allows pixels and percentages.

Potential use case: Each document is represented by an ordered list of [AnnotatedForm]s. Each form has some geometry on the source image. There are a bunch of other annotations on the source image that are unordered. These may be specific syllabary characters, notes about the handwriting, etc. Using MongoDB comparison queries, we can request a list of all spatial annotations on the same document that lie within or around the geometry of this specific word.

Implementations

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Geometry

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

impl OutputType for Geometry

fn type_name() -> Cow<'static, str>

fn create_type_info(registry: &mut Registry) -> String

Create type information in the registry and return qualified typename.

fn resolve<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, ctx: &'life1 ContextSelectionSet<'life2>, _field: &'life3 Positioned<Field>, ) -> Pin<Box<dyn Future<Output = ServerResult<Value>> + Send + 'async_trait>>
