FSF Slams Google over Dropping JPEG-XL in Chrome
The article is about avif not webp. Note the editors for the AOM avif specification don't even include Google https://aomediacodec.github.io/av1-avif/

Whistleblowers Take Note: Don’t Trust Cropping Tools
This reminds me of something similar from the guy who implemented AVIF in Firefox. He gives a talk about the implementation [1] where he talks about the CLAP privacy problem. Basically the spec adds a field that allows for cropping of the image, but the binary file would still contain the original. This would lead users to believe some image data was deleted when it really wasn't. I always thought he spent a lot of time and effort on this for little gain, but now I'm starting to think it was worth his effort.

AVIF images encoded with yuv422 appear black on iOS 16 / MacOS Ventura
So actually the same images I linked above are in the AOMediaCodec repo as well, under Link-U: https://github.com/AOMediaCodec/av1-avif/tree/master/testFiles/Link-U And I see the same issue with the yuv422 images there as well. I'm guessing Apple's AVIF implementation must be incomplete?

What is AVIF?
Created by Alliance for Open Media and worked on by Netflix, Microsoft, and Google developers, AVIF is open source - you can even weigh in on image processing and spec issues.

How can HDR AVIF stills be created?
I've been trying to find a way edit 14bit RAW files (.ARW) to an HDR capable format (HEIF/AVIF). In the process I found out there's an official AVIF encoder (1) by AOM that seems like it should be capable of creating HDR PQ stills.

Question: Multiscale AVIF performance?
AVIF can do something that resembles hierarchical JPEG and that could be useful for progressive decoding: you can have multiple layers/scales, where e.g. first a 1:4 image is encoded, then residuals to get to 1:2, then residuals to get to 1:1. Examples of this were recently added to the AVIF spec: https://github.com/AOMediaCodec/av1-avif/pull/134

Open source at Fastly is getting opener
To tie all this together, we made an org profile for our GitHub organization page. There are some great examples of these, like Microsoft and PayPal. For Fastly's, we wanted something friendly and human so we used Imagemagick to create a montage of all the avatars of the Fastly team members who have contributed to the open source projects in our org:

Video Generation with Python
Python has become a popular programming language for different applications, including data science, artificial intelligence, and web development. But, did you know creating and rendering fully customized videos with Python is also possible? At Stack Builders, we have successfully used Python libraries such as MoviePy, SciPy, and ImageMagick to generate videos with animations, text, and images. In this article, we will look closer at how Python can be used for video generation and explore some of the powerful libraries and tools that make it possible.

How Can I Streamline My Image Prep
ImageMagick is the main tool and can do most conversions and image operations. For example to resize a whole folder of photos and convert to WebP you can do this:

The Windows installer of ImageMagick will no longer be signed
Lack of open governance explains the fork in 2002. [0] The github commit history shows it's still a largely one-person-band. [1] The problems with this include a lack of succession planning, a lack of ability to scale bandwidth, and a narrower pool of ideas. The documentation website is really out-of-date as it mentions using a Borland compiler.
