带有 Manim 的长文本

编程问答 2022-05-11

问题描述

在使用 Manim 库的社区版呈现长文本时，我注意到信息呈现在可见窗口之外，效果并不令人满意。我怀疑问题的根源是 Latex 未能确保文本保持在 pdf 边界内。有没有自动换行文本的方法？我不想手动指定换行符，因为文本将不再对齐。

这是一个最小的例子：

enter image description here

from manim import *


class Edge_Wise(Scene):
    def construct(self):
        text=Tex("\\text{First we conceptualize an undirected graph  ${G}$  as a union of a finite number of line segments residing in  ${\\mathbb{{{C}}}}$ . By taking our earlier parametrization,we can create an almost trivial extension to  ${\\mathbb{{{R}}}}^{{{3}}}$ . In the following notation,we write a bicomplex number of a 2-tuple of complex numbers,the latter of which is multiplied by the constant  ${j}$ .  ${z}_{{0}}\\in{\\mathbb{{{C}}}}_{{>={0}}}$  is an arbitrary point in the upper half plane from which the contour integral begins. The function  ${\\tan{{\\left(\\frac{{{\\theta}-{\\pi}}}{{z}}\\right)}}}:{\\left[{0},{2}{\\pi}\\right)}\\to{\\left[-\\infty,\\infty\\right)}$  ensures that the vertices at  $\\infty$  for the Schwarz-Christoffel transform correspond to points along the branch cut at  ${\\mathbb{{{R}}}}_{{+}}$ .}")
        text.scale(0.6)
        self.play(FadeIn(text))
        self.wait(1)
        self.play(FadeOut(text))

解决方法

您使用的 \text 环境未包装。它旨在将文本格式化为数学模式中的文本，当您在 $...$ 之外时不需要它。以下示例为您提供两端对齐的文本：

class SquareToCircle(Scene):
    def construct(self):
        text=Tex("\\justifying {First we conceptualize an undirected graph  ${G}$  as a union of a finite number of line segments residing in  ${\\mathbb{{{C}}}}$ . By taking our earlier parametrization,we can create an almost trivial extension to  ${\\mathbb{{{R}}}}^{result}$ . In the following notation,we write a bicomplex number of a 2-tuple of complex numbers,the latter of which is multiplied by the constant  ${j}$ .  ${z}_enter image description here\\in{\\mathbb{{{C}}}}_{{>={0}}}$  is an arbitrary point in the upper half plane from which the contour integral begins. The function  ${\\tan{{\\left(\\frac{{{\\theta}-{\\pi}}}{{z}}\\right)}}}:{\\left[{0},{2}{\\pi}\\right)}\\to{\\left[-\\infty,\\infty\\right)}$  ensures that the vertices at  $\\infty$  for the Schwarz-Christoffel transform correspond to points along the branch cut at  ${\\mathbb{{{R}}}}_{{+}}$ .}")
        text.scale(0.6)
        self.play(FadeIn(text))
        self.wait(1)
        self.play(FadeOut(text))

结果： STACKOVERFLOW
