大家好,我需要缩放 tikzpicture,所以我按照以下方法操作,\begin{tikzpicture}[scale=<factor>]
但图片没有相应缩放(据 TikzManual 报道18.2 Pic 语法)。我也想缩放图片,所以我尝试了语法,\begin{tikzpicture}[scale=0.4,every pic/.style={transform shape}]
但没有成功。使用变换形状作为每张图片的选项,即,\pic[angle radius=5.3cm,transform shape]
这是可以的,但我不想在\pic
s 的每个选项上使用它。也许这只是角度库的问题(我没有尝试其他图片)。这是我的 MWE,它没有按预期工作
\documentclass[border=1cm]{standalone}
\usepackage{tikz}
\usetikzlibrary{calc,angles}
\begin{document}
%rotate vectors
\begin{tikzpicture}[vector/.style={thick,-stealth},scale=0.4,every pic/.style={transform shape}]
%drawing help lines
\newcommand*{\xmin}{-3}\newcommand*{\xmax}{4}
\newcommand*{\ymin}{-5}\newcommand*{\ymax}{1}
\draw[help lines](\xmin,\ymin)grid(\xmax,\ymax);
%vector coordinates and labels
\coordinate[label={above:$v$}] (O)at (0,0);
\coordinate (vec1)at (1,-2);
\coordinate (vec2)at(4,-1);
\draw[vector] (O)--(vec1)coordinate[label={[below]$u_1$}](u1);
%sum (vec1)+(vec2)
\draw[vector,very thick,blue](O)--($(vec1)+(vec2)$)coordinate(u1+u2);
%rotated sum (u1)+(u2) -> u'1+u'2
\draw[vector,very thick,orange](O)--([rotate=-90]u1+u2)coordinate(u'1+u'2);
%rotated vectors
\draw[red,vector] (0,0)--([rotate=-90]vec1)coordinate[label={[left]$u'_1$}](u'1);
%
\draw[red,vector] (0,0)--([rotate=-90]vec2)coordinate[label={[below]$u'_2$}](u'2);
%angles between vectors by angles library, issue with angle radius=
%default angle radius=1cm and it does not scale accordingly
\pic[draw=gray] {angle = u'1--O--u'2};
% rotation traces
\pic[draw=red,dashed,<-,angle radius=1.8cm]{angle=u'1--O--vec1};
\pic[draw=blue,dashed,<-,angle radius=5.3cm,] {angle=u'1+u'2--O--u1+u2};
%vector sums labels
\coordinate[label={below:$w$}]() at(u1+u2);
\coordinate[label={below:$w'$}] ()at(u'1+u'2);
% outgoing vector scaled accordingly but I'd rather prefer not
\path[draw,fill=white] (O)circle[radius=2pt];
\path[fill] (O)circle[radius=1pt];
\end{tikzpicture}\end{document}
下面这个可以正常工作,
\documentclass[border=1cm]{standalone}
\usepackage{tikz}
\usetikzlibrary{calc,angles}
\begin{document}
%
%rotate vectors
\begin{tikzpicture}[vector/.style={thick,-stealth},scale=0.4 ] %every pic/.append style={transform shape}
%drawing help lines
\newcommand*{\xmin}{-3}\newcommand*{\xmax}{4}
\newcommand*{\ymin}{-5}\newcommand*{\ymax}{1}
\draw[help lines](\xmin,\ymin)grid(\xmax,\ymax);
%vector coordinates and labels
\coordinate[label={above:$v$}] (O)at (0,0);
\coordinate (vec1)at (1,-2);
\coordinate (vec2)at(4,-1);
\draw[vector] (O)--(vec1)coordinate[label={[below]$u_1$}](u1);
%sum (vec1)+(vec2)
\draw[vector,very thick,blue](O)--($(vec1)+(vec2)$)coordinate(u1+u2);
%rotated sum (u1)+(u2) -> u'1+u'2
\draw[vector,very thick,orange](O)--([rotate=-90]u1+u2)coordinate(u'1+u'2);
%rotated vectors
\draw[red,vector] (0,0)--([rotate=-90]vec1)coordinate[label={[left]$u'_1$}](u'1);
%
\draw[red,vector] (0,0)--([rotate=-90]vec2)coordinate[label={[below]$u'_2$}](u'2);
%angles between vectors by angles library, issue with angle radius=
%default angle radius=1cm and it does not scale accordingly
\pic[transform shape,draw=gray] {angle = u'1--O--u'2};
% rotation traces
\pic[draw=red,dashed,<-,angle radius=1.8cm,transform shape]{angle=u'1--O--vec1};
\pic[transform shape,draw=blue,dashed,<-,angle radius=5.3cm,] {angle=u'1+u'2--O--u1+u2};
%vector sums labels
\coordinate[label={below:$w$}]() at(u1+u2);
\coordinate[label={below:$w'$}] ()at(u'1+u'2);
% outgoing vector scaled accordingly but I'd rather prefer not
\path[draw,fill=white] (O)circle[radius=2pt];
\path[fill] (O)circle[radius=1pt];
\end{tikzpicture}
\end{document}
也许有更好的方法来实现这一点,我对此持开放态度,但我不会从头开始更改我的代码。
我尝试过every pic/.append style={transform shape}
,但没有明显的效果。副作用是半径传出向量代码的最后几行被缩放,这是我不想要的。
答案1
由于您想要向每个 附加一种样式\pic{angle}
,因此您可以设置pics/angle/.append style={/tikz/transform shape}
(您需要明确说明路径,因为您在\pic
此处的“路径目录”内):
\documentclass[border=1cm]{standalone}
\usepackage{tikz}
\usetikzlibrary{calc, angles}
\begin{document}
%rotate vectors
\begin{tikzpicture}[
vector/.style={thick,-stealth},
scale=0.4,
pics/angle/.append style={/tikz/transform shape}
]
%drawing help lines
\newcommand*{\xmin}{-3}\newcommand*{\xmax}{4}
\newcommand*{\ymin}{-5}\newcommand*{\ymax}{1}
\draw[help lines] (\xmin,\ymin) grid (\xmax,\ymax);
%vector coordinates and labels
\coordinate[label={above:$v$}] (O) at (0,0);
\coordinate (vec1) at (1,-2);
\coordinate (vec2) at (4,-1);
\draw[vector] (O) -- (vec1)
coordinate[label={[below]$u_1$}] (u1);
%sum (vec1)+(vec2)
\draw[vector,very thick,blue] (O)--($(vec1)+(vec2)$)
coordinate (u1u2);
%rotated sum (u1)+(u2) -> u'1+u'2
\draw[vector,very thick,orange] (O)--([rotate=-90]u1u2)
coordinate (u'1u'2);
%rotated vectors
\draw[red,vector] (0,0) -- ([rotate=-90]vec1)
coordinate[label={[left]$u'_1$}] (u'1);
%
\draw[red,vector] (0,0) -- ([rotate=-90]vec2)
coordinate[label={[below]$u'_2$}] (u'2);
%angles between vectors by angles library, issue with angle radius=
%default angle radius=1cm and it does not scale accordingly
\pic[draw=gray] {angle={u'1--O--u'2}};
% rotation traces
\pic[draw=red, dashed, <-, angle radius=1.8cm] {angle={u'1--O--vec1}};
\pic[draw=blue, dashed, <-, angle radius=5.3cm] {angle={u'1u'2--O--u1u2}};
%vector sums labels
\coordinate[label={below:$w$}] (w) at (u1u2);
\coordinate[label={below:$w'$}] (w') at (u'1u'2);
% outgoing vector scaled accordingly but I'd rather prefer not
\path[draw, fill=white] (O) circle[radius=2pt];
\path[fill] (O) circle[radius=1pt];
\end{tikzpicture}
\end{document}
我更改了一些坐标名称,因为我不确定+
名称中是否包含 是个好主意。您可以自行决定是否遵守这一点。
如果您不想(O)
缩放 处的圆,请\pic
从此处创建一个。我们知道\pic
不受缩放的影响,并且仅pics/angle/.append style={/tikz/transform shape}
应用于。transform shape
