Struct RenderMetadata 

pub struct RenderMetadata { /* private fields */ }

Metadata describing the pixel-to-coordinate mapping of a rendered image.

This is everything a consumer needs to place and query the rendered image.

Implementations

impl RenderMetadata

pub fn width(&self) -> u32

Image width in pixels.

pub fn height(&self) -> u32

Image height in pixels.

pub fn center_pixel(&self) -> (f64, f64)

Center of the image in pixel coordinates.

pub fn pixels_per_km(&self) -> f64

Scale factor: pixels per kilometer.

pub fn max_range_km(&self) -> f64

Maximum range of the rendered data in km.

pub fn elevation_degrees(&self) -> Option<f32>

The elevation angle of the rendered sweep (if applicable).

pub fn geo_extent(&self) -> Option<&GeoExtent>

Geographic extent of the rendered area (if coordinate system was provided).

pub fn coord_system(&self) -> Option<&RadarCoordinateSystem>

The coordinate system used (if available), enabling conversion between pixel, polar, and geographic coordinates.

pub fn pixel_to_polar(&self, x: f64, y: f64) -> Option<PolarPoint>

Convert a pixel coordinate to polar (azimuth, range) coordinates.

Returns None if the pixel is outside the rendered radar coverage area.

pub fn polar_to_pixel(&self, azimuth_degrees: f32, range_km: f64) -> (f64, f64)

Convert polar coordinates to a pixel coordinate.

pub fn pixel_to_geo(&self, x: f64, y: f64) -> Option<GeoPoint3D>

Convert a pixel coordinate to geographic coordinates.

Requires a coordinate system. Returns None if no coordinate system is available or the pixel is outside the radar coverage area.

pub fn geo_to_pixel(&self, point: &GeoPoint) -> Option<(f64, f64)>

Convert geographic coordinates to a pixel coordinate.

Requires a coordinate system. Returns None if no coordinate system is available.

pub fn pixel_distance_to_km(&self, pixels: f64) -> f64

Get the range in km for a given pixel distance from center.

pub fn km_to_pixel_distance(&self, km: f64) -> f64

Get the pixel distance from center for a given range in km.
