Try to find out the height + of the skyscraper in the respective cell. There are heights of 1 to MAX + in every row, every column, and in each of the two diagonals if + indicated. Some cells may be empty (parks). The numbers around the grid + indicate how many buildings you can see from this position when you look + at the skyscraper lineup. Bear in mind that only those skyscrapers are + visible which are higher than the ones in front. Here’s a little + self-explanatory example: + + ![Skyline](http://​i.imgur.com/​BEBClaz.png) + + \begin{center} + \begin{skyline} + \skylineB{3,​{},​3,​1,​{}} + \skylineL{{},​4,​3,​{},​{}} + \skylineT{{},​{},​2,​{},​3} + \skylineR{{},​1,​3,​{},​{}} + \skylinecell{1}{3}{2} + \skylinecell{4}{2}{3} + \end{skyline} + \hspace{1cm} + \begin{skyline} + \skylineB{3,​{},​3,​1,​{}} + \skylineL{{},​4,​3,​{},​{}} + \skylineT{{},​{},​2,​{},​3} + \skylineR{{},​1,​3,​{},​{}} + \setrow{5}{5,​4,​3,​1,​2} + \setrow{4}{4,​5,​1,​2,​3} + \setrow{3}{2,​3,​5,​4,​1} + \setrow{2}{1,​2,​4,​3,​5} + \setrow{1}{3,​1,​2,​5,​4} + \end{skyline} + \end{center} + + Options + ------- + + + rows (5) + defines the number of rows in the grid + + + columns (5) + specifies the number of columns in the grid + + + sudoku (false) + sets rows and columns to 9, in case **true** is specified. Additionally the classic Sudoku grid is drawn + + + width (6.7cm) + sets the width of the minipage, in which the grid is typeset + + + scale (1) + scales the size of the grid in the minipage + + + fontsize (Large) + specifies the size of the numbers next to the grid. Here, the usual LaTeX sizes are used. Possible values: tiny, scriptsize, footnotesize,​ small, normalsize, large, **Large**, LARGE, huge, Huge + + + title () + sets the title of a puzzle + + + titleindent (0.75cm) + defines the indent of the title + + + titlewidth (5.85cm) + specifies the width of the box the title is set in + + + bgcolor () + sets the background color of the grid + + + counterstyle (none) + defines the counter style. Predefined styles: **none**, left, right + + + cvoffset (-39pt) + sets the vertical offset of the counters in the margin + + Environments + ------------ + + ###skyline + + + \begin{skyline}[options] + + \end{skyline} + + The skyline environment is the central core of the style file. With the optional + argument of the environment,​ you can reset the options with local scope. + Here, a blank grid is created. + + ###​puzzlebackground + + \begin{puzzlebackground} + + \end{puzzlebackground} + + The puzzlebackground environment allows you to place elements behind the main layer. This + is for example usefull for the \fillarea command. + + ###​puzzleforeground + + \begin{puzzleforeground} + + \end{puzzleforeground} + + The puzzleforeground environment allows you to place elements in front of the main layer. + This is for example usefull for the \framearea command. + + Commands + -------- + + ###In the grid and around + + #### skylineT + + \skylineT{csv list} + + The command typesets the numbers above the grid indicating how many + skycrapers are visible. It expects a comma-separated list as an + argument. + + #### skylineB + + \skylineB{csv list} + + The command typesets the numbers below the grid. + + #### skylineL + + \skylineL{csv list} + + The command typesets the numbers left to the grid. + + #### skylineR + + \skylineR{csv list} + + The command typesets the numbers right to the grid. + + #### skylinecell + + \skylinecell{column}{row}{height} + + The command sets the {height} of the grid cell {column}{row}. + + #### setrow + + \setrow{row}{csv list} + + The command sets the heights of {row}. It expects a comma-separated list. + + #### setcolumn + + \setcolumn{column}{csv list} + + The command sets the heights of {column}. + + #### framearea + + \framearea{color}{\tikz path} + + The command frames the area given by {\tikz path} with color {color}. The reference for + coordinates is the bottom left corner of the cell. + + \framearea{green}{(2,​2)--(2,​3)--(3,​3)--(3,​2)--(2,​2)} + + This command will color the frame of the grid cell (2,2) green. You + should consider using this command in the puzzleforeground environment. + + #### fillarea + + \fillarea{color}{\tikz path} + + The command fills the area given by {\tikz path} with color {color}. The reference for + coordinates is the bottom left corner of the cell. You should consider + using this command in the puzzlebackground environment. + + ###​Presentation + + #### definecounterstyle + + The command allows you to define your own styles. For example, the style + left is defined as follows: + + \definecounterstyle{left}{ + \begingroup\reversemarginpar\marginnote{ + \tikz\node[shape=rectangle,​fill=yellow!40,​inner sep=7pt, + ​draw,​rounded corners=3pt,​thick] + {\Huge\puzzlecounter};​}[\LP@cvoffset]\endgroup} + } + + To typeset the counter into the margin we use the command \marginnote. We need to + use the command \reversemarginpar to set the counter into the left margin. Of course, we + must use this command in a group for local scope. Finally we use \puzzlecounter in a + \tikz node with a vertical offset set with the option cvoffset. + + #### puzzlecounter + + \puzzlecounter + + The command provides the counter in textual form to use it for example + in \definecounterstyle. + + #### titleformat + + \titleformat{format} + + With the command \titleformat,​ you can define the format of the title. By default, + the definition is as follows: + + \titleformat{\centering\Large\color{blue}} + + ###​Miscellaneous + + #### skylinesetup + + \skylinesetup{options} + + With the command you can reset the options with global scope. + + #### setpuzzlecounter + + \setpuzzlecounter{number} + + With the command \setpuzzlecounter,​ you can reset the puzzle counter, for example before + the solutions. + + Supported variants + ------------------ + + ###Skyline Sudoku + + ![Skyline Sudoku](http://​i.imgur.com/​tIoe3QK.png) + + \begin{center} + \begin{skyline}[sudoku,​scale=.46] + \skylineB{4,​5,​2,​5,​2,​1,​2,​4,​3} + \skylineL{4,​2,​2,​2,​1,​3,​3,​3,​2} + \skylineT{4,​1,​3,​2,​3,​5,​3,​2,​3} + \skylineR{3,​3,​1,​3,​4,​2,​3,​2,​4} + \setrow{9}{{},​{},​{},​8,​{},​{},​{},​7} + \setrow{8}{{},​{},​4,​{},​{},​6,​{},​{},​8} + \setrow{7}{{},​2,​{},​7,​{},​{},​{},​{},​1} + \setrow{6}{{},​{},​{},​{},​8,​2} + \setrow{5}{{},​{},​2,​{},​4,​{},​7} + \setrow{4}{{},​{},​{},​3,​{},​{},​4} + \setrow{3}{{},​{},​{},​{},​1} + \setrow{2}{{},​3,​{},​{},​{},​{},​1,​2} + \setrow{1}{{},​{},​5} + \end{skyline} + \hspace{1cm} + \begin{skyline}[sudoku,​scale=.46] + \skylineB{4,​5,​2,​5,​2,​1,​2,​4,​3} + \skylineL{4,​2,​2,​2,​1,​3,​3,​3,​2} + \skylineT{4,​1,​3,​2,​3,​5,​3,​2,​3} + \skylineR{3,​3,​1,​3,​4,​2,​3,​2,​4} + \setrow{9}{3,​9,​6,​8,​5,​1,​2,​7,​4} + \setrow{8}{1,​7,​4,​9,​2,​6,​3,​5,​8} + \setrow{7}{5,​2,​8,​7,​3,​4,​9,​6,​1} + \setrow{6}{7,​4,​3,​1,​8,​2,​6,​9,​5} + \setrow{5}{9,​8,​2,​6,​4,​5,​7,​1,​3} + \setrow{4}{6,​5,​1,​3,​9,​7,​4,​8,​2} + \setrow{3}{8,​6,​7,​2,​1,​3,​5,​4,​9} + \setrow{2}{4,​3,​9,​5,​6,​8,​1,​2,​7} + \setrow{1}{2,​1,​5,​4,​7,​9,​8,​3,​6} + \end{skyline} + \end{center} + + ###Skyline Sudoku (N\*N) + + ![Skyline Sudoku (N*N)](http://​i.imgur.com/​6k4nDF8.png) + + \begin{center} + \begin{skyline}[rows=6,​columns=6,​scale=.65] + \skylineB{4,​2,​1,​3,​3,​2} + \skylineL{3,​3,​4,​3,​2,​1} + \skylineT{1,​2,​3,​3,​2,​4} + \skylineR{4,​1,​2,​2,​2,​3} + \skylinecell{2}{4}{1} + \skylinecell{4}{1}{4} + \skylinecell{5}{2}{3} + \begin{puzzlebackground} + \fillarea{Wheat}{(1,​1)--(1,​3)--(4,​3)--(4,​1)--(1,​1)} + \fillarea{HotPink!30}{(1,​3)--(1,​7)--(4,​7)--(4,​6)--(2,​6)--(2,​3)--(1,​3)} + \fillarea{GreenYellow}{(2,​3)--(2,​6)--(4,​6)--(4,​3)--(2,​3)} + \fillarea{LightBlue}{(4,​1)--(7,​1)--(7,​5)--(6,​5)--(6,​2)--(4,​2)--(4,​1)} + \fillarea{LightSalmon!50}{(4,​7)--(4,​4)--(5,​4)--(5,​6)--(6,​6--(6,​5)--(7,​5)--(7,​7)--(4,​7)} + \fillarea{LightYellow}{(4,​2)--(4,​4)--(5,​4)--(5,​6)--(6,​6)--(6,​2)--(4,​2)} + \end{puzzlebackground} ​ + \end{skyline} + \hspace{1cm} + \begin{skyline}[rows=6,​columns=6,​scale=.65] + \skylineB{4,​2,​1,​3,​3,​2} + \skylineL{3,​3,​4,​3,​2,​1} + \skylineT{1,​2,​3,​3,​2,​4} + \skylineR{4,​1,​2,​2,​2,​3} + \setrow{6}{6,​3,​4,​1,​5,​2} + \setrow{5}{5,​6,​2,​3,​1,​4} + \setrow{4}{2,​1,​3,​6,​4,​5} + \setrow{3}{1,​4,​5,​2,​6,​3} + \setrow{2}{4,​2,​1,​5,​3,​6} + \setrow{1}{3,​5,​6,​4,​2,​1} + \begin{puzzlebackground} + \fillarea{Wheat}{(1,​1)--(1,​3)--(4,​3)--(4,​1)--(1,​1)} + \fillarea{HotPink!30}{(1,​3)--(1,​7)--(4,​7)--(4,​6)--(2,​6)--(2,​3)--(1,​3)} + \fillarea{GreenYellow}{(2,​3)--(2,​6)--(4,​6)--(4,​3)--(2,​3)} + \fillarea{LightBlue}{(4,​1)--(7,​1)--(7,​5)--(6,​5)--(6,​2)--(4,​2)--(4,​1)} + \fillarea{LightSalmon!50}{(4,​7)--(4,​4)--(5,​4)--(5,​6)--(6,​6)--(6,​5)--(7,​5)--(7,​7)--(4,​7)} + \fillarea{LightYellow}{(4,​2)--(4,​4)--(5,​4)--(5,​6)--(6,​6)--(6,​2)--(4,​2)} + \end{puzzlebackground} ​ + \end{skyline} + \end{center} + + Examples & Solutions + -------------------- + + You can download application examples and their solutions from the + [project page](https://​bitbucket.org/​kleberj/​logicpuzzle/​).
