#PNG is back after 20 years!
https://www.programmax.net/articles/png-is-back/
I was hoping it dies a silent death in favour of #AVIF aed #WebP but I guess it is here to stay.
For me, I'm excited about finally integrating #APNG (animated PNG) because that has been around for years!
I even used APNG in my blog articles! (But only Firefox users can see it animated until this year. I can now see it animated in Blink-based and Chromium-based browsers in Android.)
Here's a review I wrote back in 2015 where I used APNG: https://im.youronly.one/snoworld/a-brilliant-young-mind-2015282/
But we already nave #GIF ! Well, APNG is better. 
Also see: https://docs.fileformat.com/image/apng/ (which needs to be updated with new information)
Any recommendation for an equivalent tool to pngcrush for JPG images? Or for other formats?

Auch die nahegelegenen Atolle Papua Neuguineas sind betroffen
Mit meinen Freunden @doku_eule und @fiete habe ich mal eine Doku gemacht.

After 20 years, PNG (yes the file format) gets an update. Nice! https://www.programmax.net/articles/png-is-back/
Since the #PNG spec is getting some updates, I was thinking... you know what would be sick? Baking classic #lossy compression right into PNG.
I don't mean #JPEG or anything like that. Not even the #LossyPNG scheme I enjoy using where I reduce the number of colors to reduce the entropy. That wouldn't need any changes to the spec.
I'm thinking #Amiga HAM modes! Instant 3:1 (well, 2.4:1) lossy compression with (hopefully) minimal artifacting. That would be SICK!
Makes me want to throw together a Python script or something to read PNG files, apply the HAM "compression," and then see how the output looks. It wouldn't provide much compression savings with regular PNG, it would need a change to the format. But since I never had an Amiga, I'm curious to see how it looks, and how well it might scale to modern image resolutions.
Conceptually, it's not much different than 3:1 horizontal chroma subsampling, but might actually look a lot better.
Quick explainer: instead of having a 24-bit-per-pixel image, you have a 10-bit-per-pixel image, where the first two bits are a mode selector, and the last 8 bits are the actual pixel data. The modes are Hold and Modify{R,G,B}. Modify{R,G,B} modify just the red, green, or blue component of the 24-bit color for that pixel with the 8 bits specified. The modify mode assigns that pixel to be equivalent to the 8-bit value from a pre-defined palette or some pre-defined bit-assignment mode like RRRGGGBB or something. So basically, the horizontal color resolution is divided by 3, but sometimes you get lucky and there's no noticeable loss.

Building a nation: Papua New Guinea’s 50 years of independence https://www.theguardian.com/world/2025/jul/07/png-independence-1975-50-years-anniversary-papua-new-guinea
Interesting piece on #women's role in organising and sharing #knowledge in #PapuaNewGuinea #seafaring trade, which has been assumed to be a masculine domain (by largely male anthros)
'Tattooing was an important women’s cultural practice in these regions, and tattoos signified major life stages such as marriage.
'Interestingly, the marriage tattoos used in Port Moresby and Hood Bay were identical in the 19th century, but no one that anthropologists spoke to remembered why. The tattoo designs suggest that Motu and Keapara women were once in very close contact.'
The @w3c recently released version 3 of the #PNG spec more than 2 decades after version 2 was released in 2003. The new spec largely makes official various extensions already in use like animated PNGs, HDR support, and EXIF metadata, so many browsers and graphics apps already largely support it.
Here’s an article by Chris Blume, who is the chair of the W3C PNG Working Group: https://www.programmax.net/articles/png-is-back/

The PNG format itself has just received its first update in about 20 years:
The PNG format can now support HDR images, the new HDR-capable PNG is already supported by most browsers.
Personally I'm still a fan of WebP and AVIF, much more recent standards, that support Lossless Compression just like PNG, or Lossy compression like JPG's, giving the user more flexibility. But that's just me personally.
