Yeah, it is a 30MB download on my WDL_Arch64 and 100MB installed - big deal - I've chucked out gpicview, which is rubbish in comparison to nomacs. It is free for private and commercial use. Nomacs is licensed under the GNU General Public License v3 and available for Windows, Linux, FreeBSD, Mac, and OS/2. With this feature you can easily compare images by zooming and/or panning at the exactly same position or even by overlaying them with different opacity. A unique feature of nomacs is the synchronization of multiple instances. It has a pseudo color function which allows creating false color images. Nomacs includes image manipulation methods for adjusting brightness, contrast, saturation, hue, gamma, exposure. Metadata stored with the image can be displayed and you can add notes to images. It is able to browse images in zip or MS Office files which can be extracted to a directory. Anyway, nomacs is fantastic - not only plays animated webp and any other image format I know about, but also: I don't have Inkscape lite on my computer at all - why? - becau it is rubbish compared to Inkscape full, so why bother installing it (?) when, for me, inkscape full is one of the most important/useful programs out there. Fact is, nomacs, for example, contains tons more features (and great ones) than the likes of gpicview and though it uses more resources, there are plenty of resources available on my system. However, I'm fast moving away from 'minimalism' in terms of my preferred applications. This turns out to be a big program (huge compared to the gpicview I was using as my GUI graphics viewer previously). Nomacs, which is a qt-based program (qt5 on my system anyway). Certainly my WDL_Arch64 Chromium browser can do so, but I'm looking for a simpler viewer for my WDL_Arch64 system.Īnyway, after much searching I've found one, but only one thus far: Unfortunately, I have not found any library that lets sxiv play animated webp files. However, webp animations seem to be replacing animated gifs on the web - and not surprisingly, webp is very efficient. The href attribute points to the data URI of the file, while the download attribute makes the file downloadable.I often use commandline program sxiv with -a option to play animated gifs. It programmatically creates an anchor tag and adds two attributes to it. The download function expects a data URL as a parameter and then attempts to download the file pointed by the URL to the user’s device. If the operation is successful, it resolves with the data URL else, it returns an error. This file creates and exports two functions: readFileAsBase64 expects a file blob as its input and uses the FileReader API to convert it to a data URL. Update your pages/index.js file with the following: function App ( ) The Next.js framework provides us with several ways to do server-side-related stuff within our application. To set these response headers, we will need a server. We can achieve this by setting the popular COOP (cross-origin-opener-policy) and COEP (cross-origin-embedder-policy) headers on our main document. To ensure everything works fine, we need to explicitly tell the browser that our webpage requires access to this API. npm i manipulate media assets, the module uses WebAssembly threads, and to support multithreading, these threads require some shared storage, so they use the browser’s SharedArrayBuffer API.īy default, this API is not available to webpages because of security issues. For now, we will only install subsequently, we will include using a CDN link. This package has two sub-packages: which is the FFmpeg module’s primary web assembly port, and which is the library that will be used directly in our app to interact with the former. Next, we need to install our primary dependency, ffmpeg.wasm. Project SetupĬreate a Next.js app using the following command: npx create-next-app ffmpeg-convert-image This tool allows us to handle media manipulation directly within our browsers. Here, we will see how to convert images from one format to another using FFmpeg.wasm-a WebAssembly port of FFmpeg. In this article, we’ll focus on some of the most widely used raster image formats on the web today, including JPEG, PNG, GIF, WebP and AVIF. Therefore, selecting the right image format is critical for performant web applications. Each image format provides its unique compression algorithm, encoding and decoding speeds, and specific usage requirements. Image optimization is important, and selecting the appropriate image format significantly determines image file sizes. This guide shows how to optimize images for the web by performing image transcoding directly in the browser using the FFmpeg.wasm library.
