내 문서의 한 줄당 평균 문자 수를 어떻게 계산합니까?
답변1
완벽하지는 않지만 Linux 터미널에서는 다음을 수행할 수 있습니다.
$ pdftotext -layout test.pdf
$ wc -l -w -m test.txt
출력은 다음과 같습니다.
96 986 6673 test.txt
따라서 총 문자(6637)를 줄(96)으로 나눈 값은 원하는 평균입니다(공백도 계산하지만 986 단어가 있다는 점을 고려하면 공백 없이 대략적으로 계산할 수 있습니다).
Windows 사용자의 경우 다음과 동일하거나 유사한 프로그램이 있다고 생각합니다(그러나 테스트한 것은 없습니다).화장실,xpdf(pdftotext 포함) 및무료 PDF를 텍스트 변환기로.
이 접근 방식의 한 가지 문제점은 일반 텍스트와 머리글, 그림 등을 구별할 수 없다는 것입니다.
외부 프로그램이 없으면 대략적인 예측을 할 수 있는 몇 가지 방법이 있습니다. 일부는 다음 tex(최소 아님) 예제로 자체 설명됩니다.

\section*{How to estimate characters per line win \LaTeX}
\subsection*{A dirty way: Fix {\tt textwidth} to $n$ alphabets or $n$ em units}
As you can see in the preamble, the text width of this text
is fixed to 2.5 times the length of the alphabet with 26
characters (\the\alphabet) with a default font size of
\the\oneem, resulting in \the\textwidth per line.
Therefore should be 26 * 2.5 = 65 characters per line (a
good value according to the Bringhurst rule) where each
character have a with of \the\avgchar~in average (note that is
roughly one half of the font size, i.e, each character is
aprox. $\thickapprox\frac{1}{2}$em and then fixing
{\tt \textbackslash{textwidth}} in em units allow also an
easy calculation of the number of characters.
But this prediction is only very useful if you plan to
write $n$ times of complete alphabets. Only then really 130
characters (5 alphabets) fill two lines ...
\begin{linenumbers}
\noindent \textcolor{blue}{abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmn
opqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz}
\end{linenumbers}
.
.. 260 characters fill 4 lines, and so on.
Unfortunately, for any other text this rule is less because
the proportion of each character changes. For example, the 10
first paragrahs of \emph{Lore Ipsum} (below only the first)
with this format produce 96 lines with 986 words and 6673
characters. That is 69 characters per line (counting the
spaces), not 65.
\begin{linenumbers}
\textcolor{blue}{\lipsum[1]}
\end{linenumbers}
Not too bad prediction after all, taking into account that
the thin $i$ (\the\ispace) appears 503 times while the tick
$m$ (\the\mspace) appears only 218 times, and moreover, there
are variable spaces and signs of punctuation.
Of course, you can also fix any predetermined
{\tt \textbackslash{textwidth}} in pt, cm, etc., calculate the
width of your preferred font (
\url{http://tex.stackexchange.com/questions/60277/average-width-of-popular-tex-fonts}) and then simply do some math.
\subsection*{A quicker way: the {\tt canoniclayout} package}
\begin{itemize}
\item Put {\tt \textbackslash{}usepackage\{canoniclayout\}} in the preamble
\item And {\tt \textbackslash{currentfontletters}} in the body of the document:
\framebox{\begin{minipage}[t]{1\columnwidth}%
\currentfontletters
\end{minipage}}
\item Or {\tt \textbackslash{charactersperpage}}:
\framebox{\begin{minipage}[t]{1\columnwidth}%
\charactersperpage
\end{minipage}}
\end{itemize}
Note that this package make estimates of the amount of
characters and lines that the page layout could have, do not
count the number of compiled lines\footnote{
For this you can use {\tt lineno} package as above in the \emph{Lore Ipsum} ouput}.
\subsection*{A strange way: the {\tt stdpage} package}
Produce a format with a nonproportional font but with 30
lines and 60 characters and about 1440 character (german
“Normseite”) by default. The number of characters and lines
can be adjusted:
{\tt \textbackslash{}usepackage{[}chars=65, lines=30, noindent{]}\{stdpage\}}
Probably you don't want print the final version in this
format, but temporally could be useful to compare the lengths
of text in each line, as well as the amount of pages, with the
version of the proportional font and so obtain some
information about the character density in your text.
\subsection*{Another unexplored ways}
It saw that in ConTeX (I never used) there are a
\textbackslash{averagecharwidth} command. Please see
\url{http://tex.stackexchange.com/questions/68105/macro-for-the-average-width-of-a-character}

\noindent\resizebox{\textwidth}{!}{\bf How to determine characters per line with \LaTeX}
With few \LaTeX{} commands we can see in the
compiled document the number of lines (with
package {\tt lineno}) and count the number of
words and characters for the whole documents
or some parts with the aid of the {\tt\TeX
count} program (included in \TeX{} Live).
The rest is child's play:
We can determine that in the example (see
below) the text of the example section
(without head nor float nor subsection),
there are 7-1=6 lines (see left margin) with
70 words (see page 2) and 350 characters
(see page 3), so that there is an average of
70/6 = 11.6 words and 350/6 = 58.3
characters per line.
Moreover, as frequency and with of each
character can be determined (see page 3)
it is also easy obtain the average width of
these characters in a long reference text to
make predictions of characters per line in
texts of the same language/style
that have not yet been written.
In the whole example there are 454
characters: 25 $i$ with widths of
\the\ispace{} , 16 $m$ with widths of
\the\mspace{} \dots and so on.
Therefore the average will be
$$\frac{(25*2.77)+(16*8.33)+ ...}{454}$$
And the text width (\the\textwidth{} in
the example) divided by this average will
give the prediction of characters per line.
That's all.

\section{Section: text example with a float}
Words and characters of this example file are
automatically counted from the source file
when compiled (therefore generated text as
\textbackslash{}lipsum[1-10] is {\bf not}
counted). The results are showed at the end
of the compiled version.
Counts are made in headers, caption floats
and normal text for the whole file. Subcounts
for structured parts (sections, subsections,
etc.) are also made. Number of headers,
floats and math chunks are also counted.
