Subpixel Font Demo 🔍 for RGB subpixel layouts

u/cantelope

not sure if it's rendering as intended here. i can't detect any text, and i tried for a long minute haha
u/KilledByAPixel

you may have a different subpixel layout, i took a picture https://x.com/KilledByAPixel/status/20422878…
u/kruno.ooo

mob cam should do 🔍
u/magna

Cool! You might aleady know this, but adding a blur actually makes the text more readable by reducing color fringing between bright R/G/B values. It's probably impossible to fit this on top of the 139/140 you already have, but a [1, 2, 3, 2, 1]/9 linear convolution pass could work, as briefly shown here: https://www.grc.com/freeandclear.htm

You could use clipping to have the pointing hand disappear into the OK hand if you placed the clip rectangle just right. I don't know how you would save up the characters though, maybe by using a for loop to only have one fillText call (but that would also eat characters with all the ?: statements you'd have instead).
u/magna

Yeah, clipping would make it awesome! Let's see if this can be golfed down significantly to open up space for some clipping.
u/Agnes

I posted a clipping remix. You can do scaling, translation and rotation in a single call to setTransform.

I have been golfing on this for some weeks

unfortunately I lost the origins of the code, but it was a post on codepen

The depth trick was lifted from one of u/cantelope dweets

u/pavel

Whoa!
u/Qwitter

u/UEZ

what is the purpose of -t%1?
u/danny@hille.dk

gets the fraction if t: Try writing ´throw t%1` in a dwitter editor
u/danny@hille.dk

Well i guess it's leftover code from the depth calculation golf :-) doesn't seem to do much now :-)
u/UEZ

Yep, removing it can save some bytes without any effect...^^
u/UEZ

Btw, looks very nice. :-)
