How can I draw angled lines in LaTeX to create ruled template for calligraphy?
You can use polar coordinates such as (55:100cm). In the code below, I compute the precise number of oblique lines to draw in function of the chosen angle \myAngle and the distance \myDist between two consecutive oblique lines. My code also computes the largest length needed for these lines.
\documentclass[a4paper]{article}
\usepackage{tikz}
\usetikzlibrary{calc}
\pagestyle{empty}
\newcommand*{\myDist}{1cm} % distance between consecutive oblique lines
\newcommand*{\myAngle}{55} % angle of said lines wrt horizontal, in degrees
% Distance between consecutive oblique lines, projected on the horizontal axis
\pgfmathsetlengthmacro{\horizIntervWidth}{\myDist/sin(\myAngle)}
% Length of the longest oblique lines we'll need. I add 10pt to be 100% safe
% with respect to rounding errors (the lines will be clipped anyway).
\pgfmathsetlengthmacro{\maxLength}{10pt + \paperheight/sin(\myAngle)}
% Number of oblique lines to draw
\pgfmathtruncatemacro{\maxIndex}{
round((\paperheight/tan(\myAngle) + \paperwidth)/\horizIntervWidth)}
\begin{document}
\begin{tikzpicture}[remember picture, overlay]
% Just to be sure we don't paint outside the page. :-)
\clip (current page.south west) rectangle (current page.north east);
\foreach \i in {1,2,...,30} {
\draw[black] ($(current page.north west)+(0,-\i)$) --
($(current page.north east)+(0,-\i)$);
}
\foreach \i in {0.5,1.5,...,60} {
\draw[lightgray] ($(current page.north west)+(0,-\i)$) --
($(current page.north east)+(0,-\i)$);
}
\foreach \i in {1,2,...,\maxIndex} {
\draw[red] ([xshift=-\i*\horizIntervWidth]current page.south east) --
+(\myAngle:\maxLength);
}
\end{tikzpicture}
\end{document}
This does not answer you specfic question, but can be adapted for you use with many other options built in. I have tried to set the defaults to your requirements (left in the vertical lines, but you can disable that by indlugin draw=none to the end of Vertical Line Style and Vertical Line Style Alternate.
Notes:
- There are three differnt types of lines: Horizontal, Vertical and HorizontalSlant.
- The slant angle can be set via
\SlantAngle. - Each line style has a
\tikzsetto have an alternate style applied to every nth line and each has two lines styles associated with it: the main style and an alternate line style. - The border is optional and can be disabled by setting
\MarginTop,\MarginBottom,\MarginLeftand\MarginRightto0.0cm.
