tikz-nicepoints

This is a TikZ library named nicepoints that makes it easy to draw points.

This code is similar to this TeX.SX answer

How to use it

• Put tikzlibrarynicepoints.code.tex file in a folder accessible by latex. For example in the same folder as your main file.
• Load the library with

\usetikzlibrary{nicepoints}

Basic usage examples

• [point] draws a point whose size is dependent of the current line width, whose "border" color is the salme as the text color.
  • custom size :
    • [thick,point] or [point=thick] set the point to the size corresponding to "thick" line;
    • [point size=4pt,point] or [point={point size=4pt}] set the point to the size corresponding to 4pt line.
  • custom color :
    • [red,point] or [point=red] draw the point in red
    • [point fill=yellow, point] or [point={point fill=yellow}] fill the point in yellow (the default is white)
• [point="A"] makes 3 things :
  • (1) same as [point]
  • (2) name the point coordinates as (A)
  • (3) put the label $A$ next to the point
• [point="A"*] or [point="A"'] makes the same (1) and (2), but without (3). This is equivalent to [point]coordinate(A).
• [point="A"blue] or [point="A"{blue,below}] set the style of the label $A$ to [blue] or [blue,below].
• [point={label=$B$}] is equivalent making 1) and 3), without 2).
• node[point,above]{$B$} is the same as [point] node[above]{$B$}
• \point["A"red] at (1,1); is the same as \path (1,1) [point="A"red];

More examples

• Example 1

\documentclass[border=7pt]{standalone}
\usepackage{tikz}
\usetikzlibrary{nicepoints}

\begin{document}
  \begin{tikzpicture}[scale=2]
    \draw[fill=yellow!30,very thick]
      (0,0) [point="A"] -- (1,0) {[blue,point="B"right]}
      -- node[red,point="C"*,left]{$\mathcal{C}$} (1,1) [point="D"{above,red}]
      -- (0,1) [point={red,"E"}];
    \draw[thick,purple] (E) -- (B) to[bend right] (D) edge[bend right] (C) [point=near start];
  \end{tikzpicture}
\end{document}

Layers

This library declare one additional layer called points , and draws all points in this layer. This layer sits above the main layer, so even if a point is drawn before some line, it remains visible.

If you want to add your own layers, you have to add to this layer too, for example like this

\pgfsetlayers{background,main,foreground,points}

Reset font

If the current font has a dot that is not well centered, you can reset the font used by [point] to be Latin Modern by adding the style [lmpoint].
