![]() ![]() As images have become an integral part of the web, the need for image processing becomes ever-present. If both width and height are given, the image will be resized until it reaches the maximum value for one or the other. The first argument is the rotation angle of 33 degrees. Within the function, the rotate() method of the sharp module takes two arguments. The rotateImage() function is an asynchronous function that reads an image and will return the image rotated to an angle of 33 degrees. The toFile() method is used to save the compressed image in the processed_images folder. Only JPEG pictures can use the mozjpeg property, and only WebP images can use the lossless property. The palette property, for example, is only valid on PNG images. In this example, we will demonstrate how to create a Tensorflow-based image recognition function in Rust, deploy it as WebAssembly, and use it from a Node.js app. The Fim.createImageFromPngFileAsync() and Fim.createImageFromJpegFileAsync() methods are also useful for instantiating images directly from an existing PNG or JPEG file. The image data could be loaded from a Uint8Array of RGBA values using the FimImage.loadPixelDataAsync() method. Resizing images and serving them from a CDN is the de-facto way of doing things for modern web apps and mobile apps. Optimized images mean faster load times, better SEO, and lower data costs. A gaussian blur is a technique of blurring an image using the Gaussian function, which reduces the noise level and detail on an image. You’ll also apply a gaussian blur on the rotated image. In this step, you’ll rotate the sammy.png image at a 33 degrees angle. ![]() To composite the images, you’ll chain the composite() method to the sharp instance. This will create an illusion of sammy swimming deep in the ocean. As you can see, this photo was not resized, but the file size was compressed. The height will be automatically resized to maintain the current aspect ratio. In this case, we’re dealing with a landscape image, so we’re letting the API handle the aspect ratio and just telling it what width to change the photo to. We’ve added a resize field to the object and provided some specifications for how to manipulate the image. It is designed to work in the browser as on the side in node.
