ppu-ocv/operations/border.d.ts

A type-safe, modular, chainable image processing library built on top of OpenCV.js with a fluent API leveraging pipeline processing.

import type { OperationResult, PartialOptions } from "../pipeline/types.js";
import { cv } from "../cv-provider.js";

    /** Border color in [B, G, R, A] format */

};
/** Add a uniform border around the image using `cv.copyMakeBorder`. */
export declare function border(img: cv.Mat, options: BorderOptions): OperationResult;
