Upscayl Node

Upscayl node prepares the UPSCAYL CORE to run in NodeJS.

const { join } = require("path");
const { upscaler } = require("upscayl-node");

const run = async () => {
  const outputImagePath = await upscaler.upscaleImage(
    join(__dirname, "./image-test.png"),
    join(__dirname, "./image-test-result.png")
  );
};

run();

API reference

Methods

upscaler.init(): Promise<"void">

This method allows you to load the default AI models.

upscaler.getModels(): model[]

This method allows you to obtain the path of the models. It is useful if you want to change the default model that upscales the image.

upscaler.addModel(model: Model): Model

This method allows you to add a path where you have a custom model to the list of models.

upscaler.upscaleImage(imagePath, imageOutputPath, options?): Promise<"string">

This method allows you to upscale an image with various custom options.

const { join } = require("path");
const { upscaler } = require("upscayl-node");

const run = async () => {
  // Once we have the upscaler with models loaded we can run it
  const outputImagePath = await upscaler.upscaleImage(
    join(__dirname, "./image-test.png"),       // Absolute path from image to be upscaled
    join(__dirname, "./image-test-result.png") // Absolute path from image upscaled
  );
};

run();

imagePath

Absolute image path of the image to be upscaled. Only png, jpg or webp images are accepted.

imageOutputPath

Absolute image path of the resulting image. You can choose a different image extension, which will change the image format of the original if you wish. Only png, jpg or webp are allowed.
