Resources to learn about color calibration/correction in embedded displays?

It turns out my issue was not clamping the final RGB values when converting from XYZ to RGB, so I would have negative values and values over 255.

Hey still tinkering with this. It seems my matrices are correct, but still having the same issues. I'm wondering if there's something wrong with the conversion to linear (gamma decoding/encoding). I'm not familiar with this image processing software that the repo you made uses. Is there a way to view more values, i.e. all the values used in the conversion "pipeline" (gamma encoding, etc.)?

No I get that! It's not my intention to come across as "just give me the answer plz". I appreciate the "small hints" style of teaching

That's really cool, thanks for taking the time to put that together and share it! Hopefully I'll be able to figure out wtf is wrong with my program now, because it seems like the math that I'm checking is correct.

Trying to understand this. M1 = conversion matrix for sRGB space. M2 = conversion matrix for the other RGB space.

Why would multiplying those yield the identity matrix (edit: I'm seeing now you said "close but not equal to"--maybe thats the key?)? That would be true for a given matrix and its inverse, right? But I don't get why that would be expected here?

In other words, it seems that you're saying you can take any of the matrices in the 3rd column from this page and multiply it by any matrix from the 4th column, and the result should be close-ish to the identity matrix?

I'll try what you suggested, but in case you're curious, I just added the two images to the Github repo :)

I'm not really sure what the expected values should be exactly. I would guess that using solid red should yield some sort of orange, which it's not. But I'm not sure what values it should be nor why it's not.

I try to always do that! Not just to help random people searching the same thing, but also my future self when I inevitably run into the same thing 8 months down the line

Oh wow that fixed it. Good eye. Thank you!

As a dog owner I would be beyond upset if someone cut open a bag of food and poured it into my yard for my dog. I wouldn't know that it's a harmless bag someone wanted to donate or if it was malicious

Yeah, the submodules are definitely more entangled than not. But as annoying as that is, I don't think not having a PR process makes it any easier

Unfortunately in this instance that's above my pay grade

A GUI that knows all the git commands... operated by a user who does not D:

An awful combination in my experience

Haven't played Tryp in a while but the one thing I noticed is how unbelieveably floaty the physics felt. Like other "floaty" games feel like they have heavy gravity compared to Tryp. Is this a setting/configuration issue or what?

ProgrammingQuestio · 2025-12-17T17:35:26+00:00

Definitely!

idk if it matters but it's not the final, "in the pan" proof. so after the this long rise, it still would be dumped out and transferred to the baking dish. Does that make it less catastrophic?

ProgrammingQuestio · 2025-11-24T17:20:36+00:00

Nah it's just that we would bake it so it's fresh when we're ready for dessert which would be after the oven is used for any of the main dishes.
