This image is actually an SVG that I'm intentionally exporting to a tiny JPEG to get lower quality text to match the original.

I'm using the xkcd-script font to try and match the original text as much as possible.

that was mainly a proof of concept. I think SVG is too limiting to do this dynamically, so I'm probably going to write something that uses embedded webfonts and a element, like the Death Generator already does.

I also want to make it dynamically change the image size (like some Death Generators do) where it can just get taller if you type too much text into it.

That'd be fun for some examples of "experts"

I'm also gonna have it do something I've been thinking about adding to the death generator:

Automatic alt-text generation!

It'll have a button you can press that copies some text that is the alt text for what you generated, which'll be a templated generic explanation of the comic plus whatever text you entered. That should make it easier to provide alt-text when posting these to places that want alt text

someone REALLY needs to develop an ad-hoc standard for embedding alt-text in a PNG/JPEG, though. I'd love to have the site just hand you a file that automatically has alt text when you upload it

@foone

There's 2 or so "standard" places to put it in the exif data; I haven't seen a js-only solution to use it right in the web UX, but I bet exiftool plus modern wasm tooling either already exists, or could trivially.

@foone hunh, PNG spec (circa 1996!) actually includes a way to do content warnings inside the PNG: https://www.w3.org/TR/PNG-Chunks.html#C.tEXt (not that I expect any viewer ever did a damn thing with it)

"Description" is arguably the right thing, and is already standardized! The only sticking point is that, as a thing around since 1996 with no(?) usage, it might be ruined by junk values in the wild.

Also I bet pngcrush throws these out in common usage.

@foone Ah, zTXt is preferred, to compress it.

PNG really is just the last image format we ever needed.

Written by scy on 2024-10-20 at 23:38

@foone I've thought about this multiple times, but the thing is, alt texts for one and the same image might be hugely different based upon the context in which it is used.

I mean, sure, embedding something is probably helpful nevertheless, but it's not that simple to consider all requirements.

=> More informations about this toot | More toots from scy@chaos.social

Written by Foone🏳️‍⚧️ on 2024-10-20 at 23:54

@scy oh yeah.

But for a lot of images it's possible to get a good-enough alt text automatically, because a computer is generating the image from known components.

And I'd design it as a "default alt text", not as a definitive alt text. So you could leave it, edit it down to the important things, or replace it entirely. It'd just try to save some time if possible

Written by Dillon Pentz on 2024-10-20 at 23:39

@foone My sole concern is someone will implement it into a camera app with some object identifier or AI bullshit, and other applications that might do things like redacting would not recognize and strip the metadata, causing leaks of information once something is posted and the original unredacted info is in the alt text.

@dillon @foone if your process forwards unanalysed metadata it’s a bit of a stretch to call it “redacting.”

Written by Dillon Pentz on 2024-10-21 at 00:08

@rvalue @foone Sure, but people often "redact" things in ineffective ways all the time, like covering text or faces using stickers, or they just use an application that's bad at it's job. The point is that metadata can continue to persist information about an image even when that information is no longer visible in the image itself, which can be dangerous.
