TeX - LaTeX Asked on December 8, 2021
On a DINA4 (210 × 297 [mm]) paper I want to create the following:
So I choose
usepackage[ width=16cm, height=26cm, ]{geometry}
that should allow me 8 grid-squares in the width.
But why does my grid
% Grid:
begin{tikzpicture}[every path/.style=red,
remember picture,overlay,]
draw[step=2, shift={(Textbox)}] (0,0) grid +(linewidth-0.0*pgflinewidth,-8);
end{tikzpicture}
becomes a bad look at its corners and does not match correct on the tcolorbox (even if I choose line cap=rect
)? What do I have to do?
BTW: Would it be better to create the grid as a tcolorbox too?
documentclass[a4paper]{article} % DINA4 (210 × 297 [mm])
usepackage[%showframe=true,
width=16cm,
height=26cm,
]{geometry}
pagestyle{empty}
usepackage{tikz}
usetikzlibrary{calc}
usepackage[most]{tcolorbox}
begin{document}
begin{tcolorbox}[
height=6cm,
sharp corners,
enhanced, remember, finish={%
draw[blue,ultra thick,latex-] (frame.south west) coordinate[label=135:X](Textbox)-- +(3,3) node[right]{Here to put on the grid.}; }
]
A text.
end{tcolorbox}
% Grid:
begin{tikzpicture}[every path/.style=red,
remember picture,overlay,]
draw[step=2, shift={(Textbox)}] (0,0) coordinate(X) grid +(linewidth-0.0*pgflinewidth,-8);
end{tikzpicture}
end{document}
Basing on the answer of muzimuzhi Z, I suggest a variant with a single box which integrates drawing the grid:
documentclass[a4paper]{article} % DINA4 (210 × 297 [mm])
usepackage[%showframe=true,
width=16cm,
height=26cm,
]{geometry}
pagestyle{empty}
usepackage{tikz}
usepackage[most]{tcolorbox}
begin{document}
newlength{gridlinewidth}
setlength{gridlinewidth}{.4pt} % default tikz line width
begin{tcolorbox}[
enhanced,
height=6cm,
sharp corners,
boxrule=10pt,
grow sidewards by=.5gridlinewidth,
enlarge bottom finally by=8cm+gridlinewidth,
finish={%
begin{scope}[shift={([xshift=0.5gridlinewidth, yshift=-0.5gridlinewidth]frame.south west)}]
draw[step=2, line cap=rect, red, line width=gridlinewidth]
grid +(linewidth, -8);
end{scope}
}
]
A text.
end{tcolorbox}
Text after box and grid.
end{document}
If the height of the grid should be other than 8cm (4 squares), one has to adapt enlarge bottom finally by=8cm+gridlinewidth,
and grid +(linewidth, -8);
accordingly.
If your page contains nothing after box and grid, you can omit enlarge bottom finally by=8cm+gridlinewidth,
completely.

With grid inside a new tcolorbox:
documentclass[a4paper]{article} % DINA4 (210 × 297 [mm])
usepackage[%showframe=true,
width=16cm,
height=26cm,
]{geometry}
pagestyle{empty}
usepackage{tikz}
usetikzlibrary{calc}
usepackage[most]{tcolorbox}
begin{document}
begin{tcolorbox}[
height=6cm,
sharp corners,
after skip=0pt,
enhanced, remember, finish={%
draw[blue,ultra thick,latex-] (frame.south west) coordinate[label=135:X](Textbox)-- +(3,3) node[right]{Here to put on the grid.}; },
]
A text.
end{tcolorbox}
% Grid - old
%begin{tikzpicture}[every path/.style=red,
%remember picture,overlay, %line cap=rect
%]
%draw[step=2, shift={($(Textbox)+(0.5*pgflinewidth,0)$)}] (0,0) coordinate(X) grid +(16cm-0.5*pgflinewidth,-8);
%end{tikzpicture}
% Grid - new
begin{tcolorbox}[
height=8cm,
boxrule=0pt, %frame empty,
sharp corners,
colback=white,
before skip=0pt, after skip=0pt,
%
enhanced,
underlay={begin{tcbclipinterior}
draw[step=2, red, shift={(interior.north west)}
] (interior.south west) grid (interior.north east);
end{tcbclipinterior}},
]
end{tcolorbox}
end{document}

There are differences between how the width of a tcolorbox
environment and a draw grid
are determined.
tcolorbox
environment, its total natural width is exactly linewidth
. Here the entire left and right rules are drawn within that width.draw (0, 0) grid (1, 1);
, its total width is "1cm + line width", because tikz draws a line with its center right along the path.In you situation,
draw[..., line cap=rect] (0, 0) grid +(linewidth, -8)
.tcolorbox
environment is narrower than the grid by half of grid line width, both at left and at right sides. This is what you pointed out in question comment.Here is an attempt, though not elegant enough:
tcolorbox
by half the line width of grid, both at left and at right. Now tcolorbox
has total width of "linewidth
+ grid line width", which is the same as the following grid.documentclass[a4paper]{article} % DINA4 (210 × 297 [mm])
usepackage[%showframe=true,
width=16cm,
height=26cm,
]{geometry}
pagestyle{empty}
usepackage{tikz}
usetikzlibrary{calc}
usepackage[most]{tcolorbox}
begin{document}
newlength{gridlinewidth}
setlength{gridlinewidth}{.4pt} % default tikz line width
begin{tcolorbox}[
height=6cm,
sharp corners,
boxrule=10pt,
grow sidewards by=.5gridlinewidth,
enhanced,
remember,
finish={%
draw[blue,ultra thick,latex-]
(frame.south west) coordinate[label=135:X] (Textbox) -- +(3,3)
node[right] {Here to put on the grid.};
}
]
A text.
end{tcolorbox}
% Grid:
begin{tikzpicture}[
every path/.style=red,
remember picture, overlay
]
draw[step=2, shift={($(Textbox) + (.5gridlinewidth, 0)$)}, line cap=rect]
(0, 0) grid +(linewidth, -8);
end{tikzpicture}
end{document}
