• Parameters

  • Optional config: ToJsonConfiguration

  Returns {
      contrast?: number;
      fontSize?: number;
      ocrability?: number;
      orientation?: number;
      orientationDeviation?: number;
      orientationNormalized?: number;
      plotCenter?: Point;
      plotHeight?: number;

      serialize?(config?): { readonly plotCenter?: Point | undefined; readonly plotWidth?: number | undefined; readonly plotHeight?: number | undefined; readonly ocrability?: number | undefined; ... 5 more ...; serialize?: ((config?: ToJsonConfiguration | undefined) => ...) | undefined; };
  }

  • Optional Readonly contrast?: number

    Estimated contrast of the character, in the range of [0, 1], where 0 means no contrast and 1 means perfect contrast.

  • Optional Readonly fontSize?: number

    Estimated height of the character in pixels.

  • Optional Readonly ocrability?: number

    Estimated OCRability of the character, in the range of [0, 1], where 0 means not readable and 1 means perfect readability.

  • Optional Readonly orientation?: number

    Orientation of the character in degrees counter-clockwise, where 0 means straight, and the value is in the range of [-180, 180].

  • Optional Readonly orientationDeviation?: number

    Deviation of the character's normalized orientation from dominant orientation of the line, in degrees.

  • Optional Readonly orientationNormalized?: number

    Same as orientation, but takes into account surrounding characters to smooth the orientation values of characters in a line.

  • Optional Readonly plotCenter?: Point

    Coordinates of the character's center in the image. The coordinates are in pixels, with (0, 0) being the top-left corner of the image. The rectangle described by the plotCenter, plotWidth, and plotHeight fields serve as a rough estimate of the position of the character in the input image, intended for plotting.

  • Optional Readonly plotHeight?: number

    Height of the character in pixels.

  • Optional Readonly plotWidth?: number

    Width of the character in pixels.

  • serialize?:function

    • serialize(config?): { readonly plotCenter?: Point | undefined; readonly plotWidth?: number | undefined; readonly plotHeight?: number | undefined; readonly ocrability?: number | undefined; ... 5 more ...; serialize?: ((config?: ToJsonConfiguration | undefined) => ...) | undefined; }

    • Parameters

      • Optional config: ToJsonConfiguration

      Returns { readonly plotCenter?: Point | undefined; readonly plotWidth?: number | undefined; readonly plotHeight?: number | undefined; readonly ocrability?: number | undefined; ... 5 more ...; serialize?: ((config?: ToJsonConfiguration | undefined) => ...) | undefined; }
