Hello, I started using context recently and have encountered some difficulties where I need some help to get over. (1) References in math formulas: \placeformula [Ref] \startformula \eqalignno { ... } \stopformula It seems that referencing to '\eqalignno'-formulas needs some tricks. Is there any (non-)documented way to attach a reference to a line inside '\eqalignno' multiline formula? E.g. a mechanism like \xxx[Ref] \eqalignno { ... f(x) &= x^n - 1 & \xxx[Ref] \cr ... } so one can point to \in{formula}[Ref] and get the correct reference number subsituted? (2) Left/right margins of different width in doublesided layout: I invented my favorite layout as in \setuplayout [location={doublesided,duplex}, marking=off, top=6mm, topdistance=6mm, bottom=6mm, bottomdistance=18mm, topspace=18mm, height=243mm, header=6mm, headerdistance=6mm, footer=6mm, footerdistance=18mm, backspace=46mm, width=124mm, leftmargin=12mm, leftmargindistance=4mm, leftedge=2mm, leftedgedistance=2mm, rightmargin=28mm, rightmargindistance=4mm, rightedge=6mm, rightedgedistance=2mm ] \setuppapersize [A4][A4] \setuppagenumbering [style=normal, alternative=doublesided, location={footer,middle}] \showframe and if '\showframe' is active I can verify by ruler that all distances and measures etc. are drawn correctly according to both sides of the printed sheet. (Though it remains to be investigated why only 'backspace=46mm' gives 26mm whitespace at the left paper edge, i.e. the distance from the left paper edge to the left edge of the 'leftedge'.) :-) Putting \inmargin{Some text} on evennumbered pages (in a doublesided setup) shows margin area width as in 'leftmargin' in '\setuplayout'; shouldn't it adapt itself according to doublesided layout as the margin frame does in '\showframe'? (3) Math formulas in footnotes result in "Math formula deleted: Insufficient symbol fonts." I have the same style for margins and footnotes (I hope the following setup does this as was my intention), \setupfootnotes [style=\tfx\setupinterlinespace] \setupinmargin [style=\tfx\setupinterlinespace, align=right] and in typesetting formulas in margins this error doesn't occur, i.e. there are sufficient symbol fonts available (whatever it means) :-) I am using Adobe Utopia text with Palatino math fonts. (4) HZ-algorithm. This, as well as metafun positional graphics and metapost color transparency, was the reason I started trying out context. My understanding is, HZ gets activated not with \font\tenrm=cmr10 at 10pt stretch 30 shrink 20 step 10 as documented in 'pre-hz.pdf' at PRAGMA-ADE but using \pdffontexpand\tenrm 30 20 10 1000 as I noticed somewhere. The question is, are *.tfm files like cmr10-20.tfm cmr10-10.tfm cmr10+10.tfm cmr10+20.tfm cmr10+30.tfm enough to get it going, and can be generated manually from *.afm files using 'afm2tfm'? Though, '\pdffontexpand\tenrm 30 20 10 1000' results in "Missing font identifier." in context... :-) I am using Context 2003.1.31 with pdfetex 1.10a-2.1 as in tetex 2.0.1 distributed in SuSE Linux 8.2. Thanks in advance for any help, item (1) is most critical, though. Eeri Kask
