From the reference document:

"Implementation limits", p. 991ff:

PDF itself has one architectural limit: Because ten digits are allocated to byte off-sets, the size of a file is limited to 1010 bytes (approximately 10 gigabytes).

and

The minimum allowed page size is 3 by 3 units in default user space; the maximum is 14,400 by 14,400 units. [...] Beginning with PDF 1.6, the size of the unit may be set on a page-by-page basis; the default remains at 1/72 inch. (See implementation note 177 in Appendix H.)

That implementation note, by the way, roughly states that "the UserUnit entry of the page dictionary" is more or less a dimension multiplier, and that:

Acrobat 7.0 supports a maximum UserUnit value of 75,000, which gives a maximum page dimension of 15,000,000 inches (14,400 * 75,000 * 1 ⁄ 72).

and

The magnification factor of a view is constrained to be between approximately 8 percent and 6400 percent. These limits are not fixed; they vary with the size of the page being displayed, as well as with the size of the pages previously viewed within the file.

All in all, dealing with a page of such humongous dimensions sounds rather bothersome.

I wanted to say "[citation needed]", this seems to be straight from Wikipedia (which it is, it's the last paragraph of the "File format" section).

Unfortunately there's no clear basis for this information, except a reference to the (entire) "PDF Reference".

The article image is essentially identical, but it's not the same and must have been remade at some point. I wonder if the wiki editor lives at the centre of the square?

Would you please explain about the ~~fifty ways~~ four layers?

[–] noughtnaut@lemmy.world 1 points 2 weeks ago

Didn't think one was needed.

Honestly, the Psion 5 was an absolute beauty. Also the Revo of you wanted it cheaper.

I still keep a Palm V by my nightstand because its baclklighting is just 😗👌 compared to today's thousand-nit 6" oled phones.

You'd be surprised how versatile that one thing is. Or, should I say, how much abuse it gets at ioccc.....

It does need to be Internet connected. It's critical for patching remote exploit vulnerabilities...

Thanks, fixed. Not that it matters much. 😋

 

What would happen if I tossed it in the washer (on a cold programme)? Is there another way to get old deep mud (I hope! 😬) stains out of this unknown synthetic fabric?
Where else should I ask?

 

This is likely a very niche request, but perhaps there's a genius here with the answer - or can point me to a better place to ask.

If I want it to look like a web page is loading an interlaced gif over an old modem connection, would there exist some tool to convert a given static image to an animated gif (preferably downsampled to 256 colours)?

You know, the one where it starts off as one giant coloured block which then gets progressively segmented into thinner lines with more detail as each interlaced line is received...

 

From my understanding, (a) the brain has no nerves, which is why you can talk to people while doing brain surgery on them; and (b) headache is caused by blood vessels constricting. Now, I am unsure whether migraines are also caused by blood vessels constricting, but in any case - what is it that is doing the sensing of this pain? Or is it a(nother) case of the brain just making shit up because it hates me?
