Hex Colour From Colour Selector Object

Hi All,

I'm making a HTML editor but can't figure out how to get the colour from the Colour Selector object in to a Hex colour. The object doesn't seem to support giving you the RRGGBB values to use Hex$ in MMF2?

Any help would be greatly appreciated!

Thanks,

Steve

Hex$(Red + (Green * 256) + ( Blue * 65536))

How do I grab the reds, greens and blues?

I thought that the number the selector returned would already be Red + (Green * 256) + ( Blue * 65536)

If I get the colour from the object for pure red for instance all I get is 255. How do I know what the Green and Blue should be? Pure green gives you 65280 but again how do I know that the red and blue should be zero?

GetRed(), GetGreen() and GetBlue().

Thanks guys i'm getting there!

If I select pure red and convert that using Hex$(Red + (Green * 256) + ( Blue * 65536)) all I get back is FF?

Sorry for being such a pain!

Hex$(colour) (no need for the red/green/blue functions) should get back the hex without 0s at the beginning. You need to use: left$("000000",6-len("hex"))+"hex" to add the right number of 0s to the beginning.

That doesn't work though. MMF goes like [Blue * 65536 + Green * 256 + Red].

In other words, it would output the colours in the order Blue, Green, Red. On a website, you write them in the order Red, Green, Blue, the calculation will have to be [Red * 65536 + Green * 256 + Blue].

Well then I guess you do need to do:
Hex$(GetRed(colour)*65536+GetGreen(colour)*256+Get Blue(colour))
And then:
left$("000000",6-len("hex"))+"hex"
to add the 0s to the beginning.

Thank you very much everyone, it worked a treat :D

Can't you use GetRGB() instead of Blue * 65536 + Green * 256 + Red?

If you read the rest of the thread, you'd have noticed that MMF uses Blue * 65536 + Green * 256 + Red, and for Hex RGB you need Red * 65536 + Green * 256 + Blue.

Or you can just do that :
Hex$(Red)+Hex$(Green)+Hex$(Blue)

:D

That wouldn't put 0s in. (15,15,15) would be FFF not 0F0F0F.

Ho yes, you're right :D

You could probably use GetRGB(GetBlue(colour),GetGreen(colour),GetRed(col our))
To swap the colours over instead of the formula though.

To easy fill the gaps with 0s, you can use "Sphax Formatted object". ;)

Maybe someone could post an example of this? So many methods have been discussed its getting confusing which one is the actual working one.

This example doesn't seem to work with colours like 'Bright Green'?

If you add the colour generated in to a html script it does actually come out as bright green. Could only replicate this with bright blue as well. Might be worth adding 2 more lines like the black one.
