Desparate for RGBa Color Picker

I have been frantically looking for an rgba colour picker--one that would in essence allow you to preview rgba colours. I am trying to get the right values for a development project and trial and error is proving well too time consuming.

I found the source code for one but as I've got no programming experience I could not compile it--has anyone seen an RGBa color picker or know of an application (photoshop, etc) that contains one??

For what? Do you just want a tool that will show you the palette, let you pick a color and then give you the numbers for it? Why do you want to compile it if you have no programming experience? Sorry, I'm not sure what you're looking for exactly :))

I am looking for something that shows me a pallete, and lets me choose an alpha level (by a slider, for example) then shows the RGBa value for the color I have chosen. This will let me then play around and find RGBa values I like.

softplusCommented:
Alpha is for transparency, correct? Then a simple color chooser won't work, as the "final" color depends on the color below the one you are choosing. In this situation, you'll really need two color choosers, one for the color below, one for the color above and the slider for transparency. But remember, the final color is dependant on the color below - so if you can't control the color below you never really know what color comes out :)). If you can control both colors, then you can just stick with a simple RGB chooser, as the second color + transparancy are really just an additive color mixture :))

(or maybe I'm missing something :))

Yes, it is transparency.

I understand the problems with color choice in alpha, but even something whereby you input 0-255 in RGBA and see the output color and transparency would help.

Something like this http://www.codeproject.com/miscctrl/rgba_colour_control.asp

Hi jbreq
If that's what you're looking for, do you just need someone to compile it into an executable ? :)

Try this, it's free.
If I understand you correctly, this is a easy solution for you.
Color Cop:
Features - http://datastic.com/tools/colorcop/features.php
Download - http://datastic.com/tools/colorcop/download.php

Also there's a FireFox Plugin I use and love:

While you're there browse around...

Hope this helps

the GIMP also has what you seek:

LHerrou, just a question - could I create the compiled code, host it on my site (just the binary, nothing else) and post a link to the download? Would that be allowed? (sorry, I wasn't aware of the rule).

jbreg - do you still need the binary? (The Gimp is really neat, maybe that'll cover everything for you)
0
 
jbregAuthor Commented:
I'd love the binary! Please post it if you can--if you need space I can help!

LHerrou--I believe it to be a major gap in EE that file exchange is not standardised. How much easier would it be in many questions to post a screenshot, for example? And, in situations like this where files are to be exchanged--how much better would it be if the EE forums were developed such that the exchange of files were easy and accepted? I believe this is well within the capabilities of the fine minds that frequent this site (if not most forum software that exists today), and run it for that matter...and would greatly add to the speed, consision and depth of answers in many if not most questions.

Sorry to digress--maybe not the correct forum--but this has been bugging me for a long time, and the "gentle reminder" really spurred me to make this comment.

What does everyone else think?

HeadIdiotCommented:
I believe screenshots on some occasions can be extremely helpful, but I doubt it would be in EE's best interests to give the Lizards sufficient access to their servers to post pictures.
Summed up in a word: Porno!

In regards to file exchanges, although it would help the asker, it would do nothing whatsoever to the poor sot who has the misfortune to have the same problem a year down the road and comes searching through EE for the answer.  If you've sent the file over, rather than place it in a public repository of some sorts, there would be nothing for the n00b to review.

Hi jbreg
It's even easier, you can do it yourself :))
- Go to your link: http://www.codeproject.com/miscctrl/rgba_colour_control.asp
- Register first, if you haven't already (it's free)
- Click + save as "Download demo project - 137 Kb"
- Extract the zip-file
- It will have a subdirectory "Debug" in it. Here you have a DLL and the EXE-file.

You can try to double-click the exe, possibly some DLLs are missing (I was missing mfc70d.dll and msvcr70d.dll) - you can get them here: http://www.dii.unisi.it/~gmariottini/Research/MobilitaOculare/download/ASTIDET/library%20(dll)/ - copy the dlls into the Debug subdirectory, no need to "install" them.

If it works, just keep the Debug directory with the DLLs in it.

:) I should have tried it earlier :)))

Sorry, that link should go all the way past (dll) and include the trailing slash; you'll need to copy+paste it into the browser.

There is already ample opportunity in a textual forum to post obscene content. I am certain EE has procedures to deal with--and delete--this content. Indeed, the fact that there are page editors who can comment on threads like these prove that it is well within their ability to monitor content for appropriateness and delete where it is not, and ban those who are responsible. Simply changing the medium to pictures makes little difference. There are also many forums which allow file uploads in some way--so I simply do not believe that it technically cannot be done in such a manner as to minimise the risk and reach of inappropriate content. And I also think it would be very sad we surrendered this early all the benefits of such exchanges because of a fear or potential misuse.

Regarding your second point--I was suggesting a system whereby uploaded files would be persistantly linked to questions--so when that poor sot went searching a year later--the file was still there...

Soft--will try in the AM.

jbreg,

I agree, that's an excellent suggestion. As you might suspect, it's not the only time it has come up. I'm posting below a couple of different versions (with differing responses). However, it wouldn't hurt to ask it again in the "Expert Input" or "Suggestions" TAs under Community Support (click on the "Support" link at the top right of any page, then on the left hand side you'll see the sub-TAs under Community Support).

Heh...end of which summer is right... (see post 2)

I also can't really buy the argument "our servers don't have enough storage space". Storage is cheap as chips nowadays--even a multi-TB array wouldn't require that many users @ $9 pm...especially for all the added value it would bring...

I will post this more thoroughly in those forums tomorrow...

HeadIdiotCommented:
I believe you misquoted my statement ENTIRELY.
Go back and re-read it again.
I never said they did not have sufficient storage space for pictures.  I said I doubted EE would want to give the Lizards sufficient permissions to upload.  (There is no telling what kind of crap people would post.)
From my perspective, it just adds a lot more crap the PEs would have to ride herd on...and they are kind of swamped already.

lherrouCommented:
Easy, HI, easy...

The reference to storage space came from one of the PAQs I posted. He wasn't responding to your comment at all.

jbregAuthor Commented:
Thanks Lherrou

But to respond, yes there is telling what kind of crap people would post--all kinds. Which is why:

1. Only allow certain formats
2. Only allow certain sizes
3. Scan everything for virii
4. Give moderators the right and ability to revoke files and have a complaints procedure so people can report inappropriate files to moderators for take-down. Not too different, if you think about it, than what would happen if I hurled a bunch of obscenities and pornagraphic references in this very post!

mrwebdev,

Thanks for the firefox plugin especially, but unless I am missing something neither they nor color cop allow you to specify an alpha value?

headiditot,

downloaded + installed gimp, but again can't find the ability to specify alpha channel values...does this exist, if so, where?

Softplus,

Thanks a million--got it to work--it works great (basic, but good).
