Re: HTML Color Codes
Message: 26 Date: Thu, 7 Aug 2008 01:17:36 +1000 Hi Heather You will find a ColorConverter at www.FlexibleLearning.com/xtalk that does exactly what you describe. It's a Rev stack with lots of other info built into it including color-safe sets, RGBREVHTM equivalent names etc etc. /H Last one before I jump into bed and thaw out after sitting at a computer for hours... I was wondering how to translate the RGB names to the HTML equivalent when user selects color with the Color Dialog. For such use as with a html page generator. If it doesn't exist already (though surely it's been done before, and I just can't find it): am I on the right track thinking that an array would be used to hold both code sets, then a function returns the html equivalent rather than the RGB? Or something! Though I know hardly anything about arrays, never used them - only very vaguely know what they are and what they do. Kind of. As I'm off to bed, I'll read up on them, then doze off to the sound of a script typewriter clacking in my Rev-Brainwashed noggin. :D Tia and Goodnight til Oz morn!

Re: HTML Color Codes
Thank you Eric, Mark and Sarah for fantastic help with this. I'm embarrassed to say that I only searched for HTML color, and concluded there wasn't anything to be found on this exactly. So thanks once again for pointing me in new directions. Though I have to read up about how to use libs, I wouldn't have a clue atm! But I will find out, so need to reply re this. :) Sarah I had no idea the numbers were related like that, interesting thanks for explaining. I tried out your function and mostly it worked, but sometimes it outputs a less-than-6-digit html color which causes an error when setting the backcolor of say a button to tHTMLcolor - WHICH of course I won't be doing, so not really a problem! However I'm hoping this won't make any difference with the html output when it comes time to show the color on a webpage - I wonder if it will be the correct colour? I haven't had a chance to test out such colours, but I'm guessing (hoping) that it won't?

By the way, this isn't a case where orange and red are equivalent, right?

This property sets the number of digits both before and after a decimal point. There are lots of options, but the most important thing to remember is that it will not work unless you perform a mathematical action on the variable. If you don't want to change the variable's value, just add zero to it: put baseconvert(r,10,16) into r set the numberformat to 00 add 0 to r This gives you a two-digit number in all cases. -- Jacqueline Landman Gay | [EMAIL PROTECTED] HyperActive Software | http://www.hyperactivesw.com ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Will the numberFormat work with hexadecimal numbers? That was my mistake in the function Heather, but my solution would be: if the length of r 2 then put 0 before r And repeat this for g b before assembling the HTML color string.

That was my mistake in the function Heather, but my solution would be: if the length of r 2 then put 0 before r And repeat this for g b before assembling the HTML color string. You can also use the format function to not only convert the R, B, and B numbers to hex, but pad it properly as well! put the backColor of this stack into tRGB -- 194,10,128 split tRGB by comma put format(%02x%02x%02x,tRGB[1],tRGB[2],tRGB[3]) into tHexColor put tHexColor -- c20a80 And with do, you can even do it in one line: put the backColor of this stack into tRGB -- 194,10,128 do put format( quote %02x%02x%02x quote , \ tRGB ) into tHexColor put tHexColor -- c20a80 BTW: format() cool and is great for padding zeroes or spaces in front things, so you can convert numbers to zero-padded fixed-length 6 digit numbers like this: put 5 into tNum put format(%06d,tNum)-- 05 Or if you need to pad spaces, you can omit the 0 in the format() call, so: put format(%6d,tNum) -- 5 (5 spaces, then the number 5) Have fun, Ken Ray Sons of Thunder Software, Inc.
