Framing the text area of a part page w/ tikz/pgf.

Framing the text area of a part page w/ tikz/pgf.

[Bart C. Wise]

[-- Attachment #1.1: Type: text/plain, Size: 2394 bytes --]

The code below frames the text area of a part page.  The part page removes the 
footer and headers, then I use definelayout to change the text height & width.  
It works find until I load the pgf and/or tikz modules.  When either of those 
modules are loaded, the frame is forced to the next page.  The only way I can 
make the frame stay on the page is to reduce the height of the frame; however, 
then it doesn't fit the text area that I've defined.

Why when I load the modules pgf and/or tikz does the frame for the part page 
get forced to the next page?  
How do I fix it?  
Is there a better way to do this? (don't say remove the pgf and tikz modules 
:-) ).

Thanks,
Bart

How about this setup?

\defineframedtext
   [partframed]
   [width=\textwidth,
    height=\textheight,
    rulethickness=5pt,
    top=\vfill,
    bottom=\vfill\vfill]

\setuphead
   [part]
   [before=\startpartframed,
    after=\stoppartframed,
    align=middle,
    footer=high,
    header=high,
    placehead=yes]

\starttext
\part{This is part one}
\stoptext

Thanks Wolfgang.

I like the way you implemented the solution; however, if I load the pgf/tikz 
libraries with your solution, it still forces the frame to the next page. 

Ultimately I want to load an image and have it framed for the background on 
the part page.  I like the ability that tikz gives me to adjust the opacity of 
the image, which is why I tried to find a solution using tikz.  

So I can find a solution without tikz, but is there one that will work with 
tikz?

How about this?

\setupexternalfigures[location={local,global,default}]

\setupcolors[state=start]

\definecolor[partwhite][s=1,t=.8,a=1]

\defineoverlay[partimage][\overlayfigure{mill}]

\defineframedtext
   [partframed]
   [width=\textwidth,
    height=\textheight,
    rulethickness=5pt,
    background={partimage,color},
    backgroundcolor=partwhite,
    top=\vfill,
    bottom=\vfill\vfill]

\setuphead
   [part]
   [before=\startpartframed,
    after=\stoppartframed,
    align=middle,
    footer=high,
    header=high,
    placehead=yes]

\starttext
\part{This is part one}
\stoptext

Wolfgang,

Thanks!  That one works.  And much more elegant than what I was developing.

Just so I understand:
"background={partimage,color}" : This creates the background from both the 
image and the backgroundcolor, correct?

What does the "s=1" and the "a=1" do in defining the color partwhite?  I can't 
find anything on the web.

Yes, I used here two layers for the background, one for the image and
another one for the color which is before the image.

I used s=1 to define a white color and the other two to make it  
transparent.
