Quelques problèmes des affiches générées par IA:
- toutes les informations sont mise au même niveau
- toutes les affiches s'uniformisent. Comment se démarquer des autres ?
Ce style explose, tout comme les affiches de type PowerPoint ou Word s'étaient démocratisée auparavant.
It isn’t often that new image formats land in browsers. In the early 2000s we had JPEG, GIF, and PNG. The 2010s gave us WebP, which was a modest step up from JPEG. But the 2020s have given us two new image formats that are a big step up from previous formats: AVIF and JPEG XL.
What are the advantage of JPEG XL:
- progressive rendering (the whole image can render step by step)
- excels at lossless imagery and compression improvements
AVIF excels at web-quality photographic images and images with a mix of sharp edges and flat surfaces.
XCF has been GIMP’s primary project format since 1997, and it has served many users well. Over time however, we’ve observed more and more limitations of the binary XCF format. Among other issues, it does not easily support very large or complex projects, such as the multi-page and animation features currently planned for GIMP 3.6.
The new project file format will follow a more common “zipped XML” structure. While the technical details are still being designed and implemented, this change will allow for faster saving since we’ll only need to update parts of the file instead of the whole thing each time. It will also set the stage for much desired features such as auto-saving, which will now be much more feasible.
Non destructive layer masks are also a great feature. PSD support improvements.

Exif can be useful instead of only be tagged as "privacy intrusive".
My rules of thumb
If you process pixels, normalize orientation first.
If you publish or store user images and want to preserve privacy, strip metadata intentionally.
If you parse metadata, treat it as untrusted input.
If you only need one tag, you can maybe parse one tag. If you need all the things, use a tool that has spent decades learning all the things.

A deep dive into ASCII rendering.
It seems great but I don't have time for it.

PNG renders top to bottom but the interlaced mode increase significantly the file size. WebP too at 28%.
AVIF has a progressive flag for it. It creates two layers. One at 1/8th resolution and minimum quality and one at full resolution and good quality. The first layer has 5.8kB as example, and the full image is 151kB. It's still experimental with avifenc.
JPEG XL (abbreviated JXL) renders on Chrome at 39% of the file.
The AVIF image provided as example is 56.4kB, which is incredible for a more than HD image.
For many images, there's little benefit to progressive rendering (the fox with many details is an exception). So progressive rendering is often a mix of good and bad luck.
The author claims JXL progressive rendering promises won't work, because there is a significant lag between each of the progressive rendering steps. It can work efficiently with srcset for example.
JXL still looks promising, but the AVIF progressive rendering of the fox is somewhat better than the 17-27kB alternative of JXL.
Note: a post-processed blur on a scaled down image results in 2kB. 10kB makes the image "acceptable" for the human eyes. The image is still pretty good for previews. The post-process blur would need to be part of the format, rather than left to something like CSS to make JXL.
and because it's an entirely separate image, the decoding overhead is zero if the browser doesn't see a benefit to displaying the preview. As in, in cases where the browser has the whole file, it can just skip the preview.
I will have to look after the AVIF format, because it seems to be the best of Webp (20-30% better compression), GIF (with animation) and better image quality than JPEG.
