There are a handful of clever developers who have come up with ways to do this example. Source: over 1 year ago

This doesn’t mention the API used, and the best Google gives me (via https://stackoverflow.com/questions/18680028/prevent-screen-capture-in-an-ios-app) is https://developer.apple.com/documentation/uikit/uitextinputtraits/1624427-issecuretextentry: “A Boolean value that indicates whether a text object disables copying, and in some cases, prevents recording/broadcasting and also hides the text.” ⇒ it seems... - Source: Hacker News / over 1 year ago

This is interesting from the standpoint of how new JVM features can be used to improve performance (what I presume the article's main purpose to have been), but the image processing improvement itself isn't head-turning. Also, we've found that libjpeg-turbo (https://libjpeg-turbo.org/) is ~5x (IIRC, can re-run my JMH benchmark if anyone wants me to) as fast for decoding JPEGs as ImageIO, so we wouldn't even...

For all but the simplest formats (basically BMP), the difficulty of implementing encoding/decoding from scratch is significant - well beyond a beginner's ability, and challenging/time-consuming even for senior developers. So, libraries are used in practice - e.g. Libpng and libjpeg-turbo. Source: over 2 years ago
