colors questions

[Alan Stone]

Source: texshow

(1) \setupinteraction
color                  name
contrastcolor      name

How do you set the setupinteraction contrastcolor background color ?

(2) \defineinteractionmenu, \setupinteractionmenu, \interactionbuttons

color                   name
background         screen color none foreground name
backgroundcolor  name
foregroundcolor    name

(2.1) What is "background="

- screen ?

- color ?

- foreground ?

(2.2) What's the difference between

- "color" and "foregroundcolor" ?

- background=name and backgroundcolor=name ?

- how do you set a, or override (1)'s, selected item background color ?

hm, there is no interactionbackgroundcolor (maybe some day in mkiv when 
i've redone hyperlinks)

grayscale

color

color of content (like text)

foregroundcolor is somewhat special in the sense that it applies to the 
'framed' content; in mkiv we use whatsits to track color and using 
colors around your boxed content might interfere so therefore we have 
this special less interfering foregroundcolor; in mkiv this interference 
is gone (by design)

> - background=name and backgroundcolor=name ?

background={somecolorname,somebackgroundthing,somemore)

i.e. can be a sequence of things to be applied (just grep for 
background= in the s-*.tex files)

Hans

(keep in mind that tex itself has no concept of color, nor of backgrounds)

Thanks Hans.

Still about setupinteraction's "contrastcolor".

In an interactionmenu, how do you maintain an item's color to
"contrastcolor" when the corresponding section spans over more than
one screen/page ? It switches back to "color" after the first
screen/page.

indeed, just a compare of the reference page with the current page; no 
spans

That's a feature request then. Samewise for interaction buttons.

Thanks,

\bTABLE and \chemical

[Alan BRASLAU]

I have not understood how tables and \chemical interact.
The second case in the minimal example below
demonstrates unexpected/incorrect centering
when using \chemical and \bTABLE.
Am I missing something?

Thanks.

Thank you. This works, of course.
I suppose that it is a subtlety why this is
necessary with \bTable but not with \starttable...

Should this perhaps be included in \startchemical
or would that wreak havoc elsewhere?
