What is @loaders.gl/images?
@loaders.gl/images is a part of the loaders.gl suite, designed to handle image loading and processing. It provides utilities for loading, parsing, and manipulating image data in various formats.
What are @loaders.gl/images's main functionalities?
Loading Images
This feature allows you to load images from a URL or file. The `load` function from `@loaders.gl/core` is used in conjunction with `ImageLoader` from `@loaders.gl/images` to fetch and parse the image.
const { load } = require('@loaders.gl/core');
const { ImageLoader } = require('@loaders.gl/images');
async function loadImage(url) {
const image = await load(url, ImageLoader);
console.log(image);
}
loadImage('https://example.com/image.png');
Parsing Image Data
This feature allows you to parse raw image data from an ArrayBuffer. The `parse` function from `@loaders.gl/core` is used with `ImageLoader` to interpret the image data.
const { parse } = require('@loaders.gl/core');
const { ImageLoader } = require('@loaders.gl/images');
async function parseImageData(arrayBuffer) {
const image = await parse(arrayBuffer, ImageLoader);
console.log(image);
}
// Assuming arrayBuffer contains image data
parseImageData(arrayBuffer);
Image Manipulation
This feature allows you to manipulate image data after loading it. The `getImageData` function extracts image data that can be further processed or manipulated.
const { load } = require('@loaders.gl/core');
const { ImageLoader, getImageData } = require('@loaders.gl/images');
async function manipulateImage(url) {
const image = await load(url, ImageLoader);
const imageData = getImageData(image);
console.log(imageData);
}
manipulateImage('https://example.com/image.png');
