Image Types

ImageInterpolation

enum ImageInterpolation {
  NEAREST = 'NEAREST',
  LINEAR = 'LINEAR',
  CUBIC = 'CUBIC',
}

Image interpolation method.

  • NEAREST - no interpolation, fastest

  • LINEAR - medium interpolation quality

  • CUBIC - best interpolation quality, slowest

ImageType

enum ImageType {
  SCALAR = 'SCALAR',
  VECTOR = 'VECTOR',
}

Image type.

  • SCALAR - contains a single variable

  • VECTOR - contains two variables, u and v vector components

ImageUnscale

type ImageUnscale = [min: number, max: number] | null;

Value bounds to unscale image data to original data, or null if image contains original data already and no unscaling is needed.

ImageProperties

interface ImageProperties {
  image: TextureData;
  image2: TextureData | null;
  imageSmoothing: number;
  imageInterpolation: ImageInterpolation;
  imageWeight: number;
  imageType: ImageType;
  imageUnscale: ImageUnscale;
  imageMinValue: number | null;
  imageMaxValue: number | null;
}

Properties to render a single image.

DirectionType

enum DirectionType {
  INWARD = 'INWARD',
  OUTWARD = 'OUTWARD',
}

Direction type to be used for formatting.

  • INWARD - formats direction inwards from outside to the current point

    • meteorological - wind, waves

  • OUTWARD - formats direction outwards from the current point to outside

    • climatological data - currents

DirectionFormat

enum DirectionFormat {
  VALUE = 'VALUE',
  CARDINAL = 'CARDINAL',
  CARDINAL2 = 'CARDINAL2',
  CARDINAL3 = 'CARDINAL3',
}

Direction format to be used for formatting.

  • VALUE - formats direction as a value in degrees

  • CARDINAL - formats direction as a 1-letter cardinal (4 possible values)

    • N, E, S, W

  • CARDINAL2 - formats direction as a 2-letter cardinal (8 possible values)

    • N, NE, E, SE, S, SW, W, NW

  • CARDINAL3 - formats direction as a 3-letter cardinal (16 possible values)

    • N, NNE, NE, ENE, E, ESE, SE, SSE, S, SSW, SW, WSW, W, WNW, NW, NNW

Placement

enum Placement {
  BOTTOM = 'BOTTOM',
  TOP = 'TOP',
  RIGHT = 'RIGHT',
  LEFT = 'LEFT',
}

Tooltip control placement from the mouse cursor position.

Load Types

TextureData

interface TextureData {
  data: Uint8Array | Uint8ClampedArray | Float32Array;
  width: number;
  height: number;
}

Texture data to be used as input to raster rendering layers.

UnitFormat

interface UnitFormat {
  unit: string;
  scale?: number;
  offset?: number;
  decimals?: number;
}

Format definition to be used for formatting raw values with units.

RasterPointProperties

interface RasterPointProperties {
  value: number;
  direction?: number;
}

Raster point properties for a particular position.

Datetime Types

DatetimeISOString

type DatetimeISOString = string;

Valid ISO 8601 datetime.

DatetimeISOStringRange

type DatetimeISOStringRange = [start: DatetimeISOString, end: DatetimeISOString];

Valid ISO 8601 datetime range.
