extra offsets

extra offsets

[Hans Hagen]

Hi,

concerning the offsets in framed ..

- we cannot use leftoffset etc as name because these are already used in 
  mechanisms that build on top of framed and it would add quite some 
extra code (and probably bugs) to those mechanisms

- adding additional rulethickness variants is non trivial since the 
rulethickness is also used elsewhere (rounded corners etc) and the code 
would become rather messy; also, we can use mp for special frames (after 
all, extra thickness makes no sense without extra colors)

so, as an experiment i added support for extra offsets but these work 
*on top* of the existing offset; they have names like loffset, roffset, 
toffset and boffset; the speed penalty is neglectable

(only mkiv because it has a more clever inheritance model for derived 
framed mechanisms)

Hans

ps. for quite a long time there is a command \offset which takes 
leftoffset cum suis plus some more

Thank you very much for now finally adding this, it's a big improvement
for natural tables and allows us to do some fancy things.

keep in mind that you can use the offsets combined, so

toffset=2cm,loffset=1cm,offset=1cm

I noticed this, it requires a few more settings than my code  
(offset=0pt,...)
but it gives us more possibilities and prevents a few problems.

\setupTABLE                
[frame 
= 
off,topframe=on,bottomframe=on,offset=0pt,toffset=0.25ex,boffset=0.25ex]
\setupTABLE[column]       [loffset=1em,roffset=1em]
\setupTABLE[column][first][loffset=0em,roffset=1em]
\setupTABLE[column][last] [loffset=1em,roffset=0em]

\starttext

\bTABLE
   \bTR
     \bTH Knuth \eTH
     \bTH Zapf  \eTH
     \bTH Tufte \eTH
   \eTR
   \bTR
     \bTD \input knuth \eTD
     \bTD \input zapf  \eTD
     \bTD \input tufte \eTD
   \eTR
\eTABLE

\stoptext
