partial hz ?

partial hz ?

[Steffen Wolfrum]

Hi,

hz justification brings better results, sometimes (most paragraphs don't change), but the entire typesetting is generally slow down with hz almost by factor 2.
Thus I'd like to have a a kind of "partial hz" that I can use on selected paragraphs only.


I hoped it should work like this:

\startfonthandling [stpure]
  \defineprotrudefactor endash 0 0.25
  \defineprotrudefactor hyphen 0 0.5
  \defineprotrudefactor / 0 0.5
  \defineprotrudefactor , 0 0.5
  \defineprotrudefactor . 0 0.5
  \defineprotrudefactor : 0 0.5
  \defineprotrudefactor ; 0 0.5
  \defineprotrudefactor - 0 0.5
  \defineprotrudefactor quotedblleft 0 0.25
\stopfonthandling
\definefonthandling [stpure]              [stpure]                       [type=hanging]
definefonthandling [sthighquality]     [hz,stpure]
\setupfonthandling [hz] [min=20,max=20,step=5]
\setupfontsynonym [Serif] [handling=sthighquality]
\setupfontsynonym [SerifBold] [handling=sthighquality]
\setupfontsynonym [SerifSlanted] [handling=sthighquality]
\setupfontsynonym [SerifItalic] [handling=sthighquality]
\setupfontsynonym [SerifBoldSlanted] [handling=sthighquality]
\setupfontsynonym [SerifBoldItalic] [handling=sthighquality]

\usetypescript[postscript][\defaultencoding]
\setupbodyfont[postscript,10pt]

\setupalign[block,hanging]

... and chosen paragraphs I'd wrap with a ...

\setupalign[block,hanging,hz]


But this doesn't make any improvement in speed.
The only relevant change seems to be
definefonthandling [sthighquality]     [hz,stpure]
 When this is changed to
definefonthandling [sthighquality]     [stpure]
then typesetting speeds up, of course.

But this gives me no choice between main text without and selected paragraphs with hz...



Any ideas?

A factor of 2 is good :) For my document, hanging punctuation slows 
down things a LOT (from 10 sec for three runs, to 60 secs for three 
runs). What I usually do is to use no protrusion for test runs, and 
add protrusion when I really have to make the final document. This can 
be done easily using something like

\startmode[final]
   \usetypescript[serif][hanging][normal]
\stopmode

\usetypescript[mainface][texnansi]

\doifmode{final}{\setupalign   [hanging]}

Then add --mode=final flag to texexec when I want protrusion.

Sorry, no idea about this.

hm ... hanging doesn't make much change for me: with 263 sec, without 238 sec.
no, here it is hz. it doubles speed (resp. slowness): 416 sec
