Struct RenderResult 

pub struct RenderResult { /* private fields */ }

The result of a render operation.

Bundles the rendered RGBA image with metadata describing the pixel-to-coordinate mapping, enabling a consuming application to accurately place the image on a map, draw overlays, and query data values.

Implementations

impl RenderResult

pub fn new(image: RgbaImage, metadata: RenderMetadata) -> Self

Create a new render result from an image and metadata.

pub fn image(&self) -> &RgbaImage

The rendered RGBA image.

pub fn into_image(self) -> RgbaImage

Consume the result and return the image.

pub fn metadata(&self) -> &RenderMetadata

Metadata describing the pixel-to-coordinate mapping.

pub fn save<P: AsRef<Path>>(&self, path: P) -> Result<()>

Save the rendered image to a file.

The output format is inferred from the file extension (e.g., .png, .jpg). This is a convenience wrapper around image::RgbaImage::save.

Errors

Returns an error if the file cannot be written or the format is unsupported.

pub fn query_pixel( &self, field: &SweepField, x: f64, y: f64, ) -> Option<PointQuery>

Query the data value at a pixel coordinate.

Uses the metadata’s pixel-to-polar conversion and then looks up the value in the provided field. Returns None if the pixel is outside the rendered area.

pub fn query_polar( &self, field: &SweepField, azimuth_degrees: f32, range_km: f64, ) -> Option<PointQuery>

Query the data value at a polar coordinate.

pub fn query_geo( &self, field: &SweepField, point: &GeoPoint, ) -> Option<PointQuery>

Query the data value at a geographic coordinate.

Requires a coordinate system in the metadata. Returns None if no coordinate system is available or the point is outside the rendered area.

Trait Implementations

impl Debug for RenderResult

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

Formats the value using the given formatter.
