Hi all,
At the end of June, Hans uploaded a new lmtx version which included
improvements to par building which he and Mikael had been working on in
math mode. Hans suggested in the online chat that these improvements may
be useful in typesetting novels. I was keen to try these since I have
typset novels in the past.
I have ran some tests on two novels which I downloaded from the
Gutenberg Project site as epubs and extracted them to get the original
xhtml files which I then typeset in context. I made very little in the
way of changes to the files so that my setup for xml was very simple.
Here are my setups for the layout of the novels showing some trackers
that were used as well:
\definepapersize[pagee][width=5.06in,height=7.81in]
\setuppapersize[pagee]
% XML setups here
\startsetups[grid][mypenalties]
\setdefaultpenalties
\setpenalties\widowpenalties{1}{150}
\setpenalties\clubpenalties {1}{150}
\stopsetups
\setuplayout[
width=10cm,
topspace=0.5in,
backspace=2.0cm,
header=7.5mm,
footer=0.25in,
location={middle,middle},
vs=2,
grid=yes,
setups=mypenalties
]
%\enabletrackers[makeup]
%\enabletrackers[builders.hpack.quality]
\enabletrackers[builders.hpack.overflow]
%\enabletrackers[layout.vz]
%\enabletrackers[paragraphs.passes]
\enabletrackers[paragraphs.passes=summary]
%\enabletrackers[paragraphs.passes=details]
\setupalign[granular]
%\setupalign[nothyphenated,hz,verytolerant]
%\setupalign[vertical,height]
%\setupalignpass[decent]
%\setupalignpass[quality]
%\setupalignpass[test1]
\setupalignpass[test2]
%\setupalignpass[test3]
%\setupalignpass[test4]
%\setupalignpass[test5]
%\setupalignpass[optional1]
%\setupalignpass[test2b]
\starttext
\setuppagenumbering[location={footer,middle},alternative=doublesided,state=start]
\setcounter[userpage][1]
%\showmakeup[vbox]
%\showlayout
\dostepwiserecurse{0}{30}{1}{
\xmlprocessfile{mysetups}{/path to xhtml
files/4439720318703948998_84-h-\recurselevel.htm.xhtml}{}
}
\stoptext
Below are the result showing the number of overfull boxes for these
novels using the setups in the file spac-imp-tests.mkxl . See the manual
Low Level - Lines
Test Novel1 Novel2
Test1 70 35
Test2 30 8
Test3 62 23
Test4 89 40
Test5 28 9
Optional1 55 19
Quality 74 32
Decent 39 11
From these initial tests one can see that Test2 gave the lowest number
of overfull boxes. So I edited test two, ran it, and the results are below.
Test Novel1 Novel2
Test2b 11 0
My setup for test 2b is as follows:
\startsetups align:pass:test2b
\pretolerance 100
\tolerance 200
\parpasses 3
classes \indecentparpassclasses
threshold 0.025pt
tolerance 800
extrahyphenpenalty 50
next
threshold 0.025pt
tolerance 900
adjustspacing 3
adjustspacingstep 1
adjustspacingshrink 10
adjustspacingstretch 15
next
threshold 0.025pt
tolerance 1000
adjustspacing 3
adjustspacingstep 1
adjustspacingshrink 20
adjustspacingstretch 40
emergencystretch .25\bodyfontsize
\relax
% \linebreakpasses\plusone
\stopsetups
The only difference between test 2 and 2b are that I increased the
tolerance in each of the three passes.
In novel 2 this was successful in eliminating the overfull boxes but not
in Novel 1 although I noticed that majority of overfull boxes were above
1pt with the largest about 12pt in Novel 1.
I am at the stage now where I need some kind of strategy to
reduce/eliminate overfull boxes, other than changing the tolerance, and
I'm hoping for some advice from the community. Suggestions for further
reading particularly on the commands in \setupalignpass and their usage
would be appreciated and on the best way to tackle overfull boxes.
Best Wishes
Keith McKay
