Hans, I definitely see problems with the \starttextbackground[]-\stoptextbackground environment (discussed in the "displays"-brochure). When the textbackground falls at a page crossing -- i.e. starts at the top of a page -- the coloring extends backwards on the page just left. It can be remedied by putting a \null just in front of \starttextbackground. The extra vertical space this introduces just manages to constrain the background to its own page. However, this is not a general solution, on other places the extra vertical space is certainly not wanted. I cannot find the exact nature of the problem. I suspect it has to do with the \output-routines, but these are not my speciality, to say the least. So, not much help there, Also, the \starttextbackground does not respect footnotes, these are colored. In contrast, the old \startbackground-\stopbackground does respect footnotes. The coloring stops at the footnote and restarts at the next page. I should like that for \starttextbackground as well. Hans van der Meer

can you make me a minimal example of where things go wrong (keep in mind that there are two methods, tex and paragraph) with respect to footnotes, maybe i can make that an option (there are more exceptions) Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | fax: 038 477 53 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Here is the smallest one I could construct that shows the page crossing effect. I used the "location=paragraph". With "location=text" I did not experiment. Here follows the code: % testing textbackgroundcolor \setupbodyfont[12pt] % using the default cmr font \setuppapersize[S6][S6] \setuplayout[width=middle,location=middle,header=0pt,footer=4ex] \setuppagenumbering[location={footer,inright},alternative=singlesided] % \setupcolors [state=start] \definecolor [lavender] [r=.901961,g=.901961,b=.980392] \definecolor [lavenderblush] [r=1,g=.941176,b=.960784] % general page coloring \setupbackgrounds[page][background=color,backgroundcolor=lavenderblush] % % special background coloring for parts of the text \definetextbackground[A][frame=off,location=paragraph, backgroundcolor=lavender,backgroundoffset=0pt] \starttext % \dorecurse{10}{Some text that must fill a portion of the page. }\par \dorecurse{10}{Some text that must fill a portion of the page. }\par \dorecurse{10}{Some text that must fill a portion of the page. }\par % % WITH 8 AND 9 IN THE NEXT RECURSION THE FIRST PARAGRAPH ON PAGE 2 HAS % THE BACKGROUND COLORED BUT THE WHITESPACE BELOW THE LAST PARAGRAPH ON % PAGE 1 IS COLORED TOO. % CHANGE THE 8/9 TO 10 AND THE COLORING ON PAGE 1 DISPAPPEARS. % I HAVE BECOME ACROSS SITUATIONS WERE THE COLORING EXTENDED STILL % FURTHER BACK OVER MORE PRECEDING PARAGRAPHS, BUT IT IS DIFFICULT TO % CONSTRUCT A MINIMAL EXAMPLE FOR THAT. \dorecurse{9}{Some text that must fill a portion of the page. }\par % % THIS SHOULD COLOR THE FIRST PARAGRAPH ON PAGE 2 \starttextbackground[A] \dorecurse{5}{Text with the background. } \stoptextbackground \dorecurse{10}{Some text that must fill a portion of the page. }\par % \stoptext I hope you can find what causes it, because I like the effects. Keeping footnotes free from the coloring would be very great if it could be accomplished (same as for interposed floats), like: -- text on page containing reference to footnote, not colored background -- text on page with colored background -- footnote not colored (or perhaps the same coloring as where the reference occurs?) -- text on next page goes on with colored background Hans van der Meer
