so what is your screen resolution, 640x480 ?
**sigh** so many people talk about the number of pixels and not the pixel
density. 640x480 would look very sharp indeed on a 5cm x 3cm screen.
so how many pixels per character in a 60 character line do you need
My screen is about 141 DPI. Not super high-res, but a whole lot better
than those "crimes against humanity" 96 DPI screens.
interesting is that 1920x1200 often (on windows) looks quite ok (but
depending on where i dock the laptop I have upto 4K so various resolutions
and sizes, these (even older) monitors run forever)
How big is that screen? 12"? 17.3"?
i have various sizes, most are older dell's (the sturdy black ones you
can bey cheap second hand); the low energy newer 4K is seldom used
because I work on a (some) 70 inch 4K screen (3 m distance) that my
brother put here when i had eys issues (the problem there is that these
never hava a real resolution in the sense that stuff shifts, this oled
tech, so the edges can clip off)
the smallest screens are laptop (17 in) and a rpi screen (for the energy
friendly setups and testing) ... zero changes for updating to some fancy
4K laptop (tex is tiny to zero tech after all)
ok, i lied, the smallest screen is the phone but only tex on that for
teasing
Most non-SPR'ed text looks "fine" on my (1920x1080) screen. But even at
141 DPI, SPR'ed text looks noticeably better to me.
well, one reason for using windows is that it always looked ok
And, for reasons I don't understand (and maybe never will), Pagella looks
awful in my ancient AR when it is not SPR'ed. Really awful. 7x13 X fonts
from 1985 look better. Recently someone (another person who may not want
his name connected to this thread) asked me about using Pagella for
ANSS-CE. I could not understand why anyone would want that, because it
looked so bad. But then I realized it looked bad in my AR when the page
wasn't SPR'ed.
maybe no / less hinting .. who knows, i only use ubunto on linux as that
is set up right wrt these things
You can always force a good old 320 horizontal pixel resolution experience:
\startMPpage
triplet bm ; bm := loadbytemapfromfile(3, "PageLayout.png") ;
lmt_filter [
source = 3,
target = 4,
% filter = "sharpen:5",
% filter = "gaussianblur",
% filter = "sharpen:5,gaussianblur",
filter = "gaussianblur,sharpen:5",
] ;
draw bytemap 4 xsized 20mm ;
\stopMPpage
(and then spend an evening writing your own filters that you can plug in)
I can't possible imagine why I would ever want to, and yet I'll keep this
message just in case that day comes.
come on, i know that you love these techniques ... everything
interesting graphic is from the previous century so it must be familiar
to you; it all being old means you can ask (google) ai to explain it if
needed (so that you then know what wikipedia page and books / articles
to read)
