I wish we could ping people from chat that haven't been here. Allow users to block that, of course, but it'd be handy in cases like now when I want to tell TunaMaxx to look at the improved edit I made on graphicdesign.stackexchange.com/posts/81300/revisions
I have a question, and I am not sure if it belongs here, or somewhere else on the SE network> It is (i think) really technical, and I think if I asked on the wrong site it will not get a useful response.
Now, I don't really understand what XRD is (which perhaps would be a good question itself) But my vague notion is that it captures the intensity of refelected electromagnetic radiation at different frequencies, for different input frequencies.
> X-ray powder diffraction (XRD) is a rapid analytical technique primarily used for phase identification of a crystalline material and can provide information on unit cell dimensions.
So my question is (and I've been wondering this for a few months), is it possible to algorithmically convert from a XRD to a (A)RGB triple that I can display on a monitor, or ((A)CYMK) to print in a book.
And I am not sure if this a question for Graphic Design stack exchange, or Physics stack exchange, or maybe Photography stack exchange.
@LyndonWhite It's kinda asking to convert from a physical property to a digital one. I think Physics would bounce this to us and we to Physics... tough nut
A process that can fail (particularly if it fails in defined ways, at defined times) is still interesting to me (Probably more so that something that always works, eg RGB<->HSV)
So the reason I am interested in this, is that I am interested in making a machine-learning-based natural language processing/generation system for generating colors based on descriptions (eg "Bright redish green") and generating descriptions from colors
I have about 4000 such named colors, and I was wondering about extending towards pigment databases as another source of informantion
There's a lot of different ways to make a cyan printer ink, or a blue light, and none of them have anything to do with Prussian Blue--whose intensity varies based on the size of its particles.
So, yeah, people can agree on what Prussian Blue is (a pigment produced by oxidation of ferrous ferrocyanide salts) but agreeing on what CMYK or RGB value replicates it? Hah.
There's literally not one answer. It's not subject disagreement, "Prussian blue" covers a wide span of blues.
And depending on what it's suspended in, you can get oil paint, watercolour paint, acrylic paint... all of which is Prussian blue, has its own qualities of transparency and reflectivity, and varies in intensity depending on the size of the particles in the colloidal dispersion.
To your original question: I think you're gonna have to break it down into bite-size chunks for multiple Stack questions, probably across multiple Stacks.
And please, keep me updated on the project, I'm very interested.
It is the challenges (even in RGB-Monitor space) that make it interesting. As a subfield of linguistics, I think color naming is very dense in terms of having challenges (Eg ambiguities, pragmatic differences etc).
Which I suggest makes it a good area to pilot test systems for general NLP/ computational linguistics.
eg, English doesn't really go in for reflectivity as a primary color descriptor but some languages/cultures group colors by that, or by intensity, or...
(Hue is our primary descriptor.)
The most commonly known example is classical Greek, which considers the sky to be bronze-like and the sea to be wine-like.
I use a blogging platform called Octopress which is built on Jekyll which isn't that hard, especially after the initial setup. It's a static website generator, meaning it only changes when I tell it to update on my local PC and then FTP the file changes over to the server
You can get MathJax support with Jekyll
Someone online says you get get MathJax for Tumblr too
Command (Cntrl) and = gives zoom in, in Adobe Illustrator.
Is there a way to set it so that it zooms to the selected object rather than the centre of the screen?
