Hi, Adytia pointed me to some examples at http://wiki.contextgarden.net/Protrusion I tried the following code with a couple of page test page, ----- \definepapersize[specialbook][width=5.5in,height=8.5in] \setuppapersize[specialbook][specialbook] \setuplayout[height=7.5in,width=4.5in,backspace=40pt,location=middle] %\usetypescript[serif][hz][quality] %line 1 %\setupalign[hanging,hz] %line 2 \usetypescript[serif,sans,mono][hanging][pure] %line 3 \setupalign[hanging] %line 4 \usetypescript[modern-base][texnansi] %line 5 \setupbodyfont[reset] %line 6 \setupbodyfont[modern] %line 7 %\setupbodyfont[serif,11pt] \setupwhitespace[4.5pt] \setupcolors[state=start] \setupexternalfigures[directory={../marsh-slideshow}] \setupindenting[none] \setuphead[chapter][number=no] \setupheader[state=none] % Enable colors and activate hyperlinks \setupcolors [state=start] \setupinteraction [state=start, color=blue] \definecolor [darkRed][r=.5,g=.0,b=.0] \useURL[TPJ][{http://www.tug.org/pracjourn}][][{\it Prac\TeX{} Journal}] \useURL[mywebsite][{http://www.walden-family.com/dave}][][www.walden-family.com] \starttext ... \stoptext ---- and I get slightly different results if lines 1 and 2 versus 3 and 4 are in or out, or if both pairs of lines are commented out. If, however, I try this with the real 215 page book I am compiling rather than a smaller example, pdfTeX halts 200 or so pages in with a fatal error saying it has run out of space and saying something more about a hash table. If I comment out lines 5-7, I don't get the fatal error but also I don't think I see protrusion and font expansion happening. The real book doesn't have very much body text but is does have 215 images with code like \placefigure{none}{\externalfigure[#1.jpg][width=\textwidth]} where #1 comes from a macro call. Any thoughts? (I suppose I can split my source file in half and find a ConTeXt command to start the page numbering for the second half a 107 or so and then combine the two PDFs with Acrobat.)
