MathTex

Qualified name: manim.mobject.text.tex\_mobject.MathTex

class MathTex(*tex_strings, arg_separator=' ', substrings_to_isolate=None, tex_to_color_map=None, tex_environment='align*', **kwargs)

Bases: SingleStringMathTex

A string compiled with LaTeX in math mode.

Examples

Tests

Check that creating a MathTex works:

>>> MathTex('a^2 + b^2 = c^2') 
MathTex('a^2 + b^2 = c^2')

Check that double brace group splitting works correctly:

>>> t1 = MathTex('{{ a }} + {{ b }} = {{ c }}') 
>>> len(t1.submobjects) 
5
>>> t2 = MathTex(r"\frac{1}{a+b\sqrt{2}}") 
>>> len(t2.submobjects) 
1

• Parameters:
  • tex_strings (str)
  • arg_separator (str)
  • substrings_to_isolate (Iterable *[*str ] | None)
  • tex_to_color_map (dict *[**str* *,* ParsableManimColor ] | None)
  • tex_environment (str | None)
  • kwargs (Any)

_break_up_by_substrings()

Reorganize existing submobjects one layer deeper based on the structure of tex_strings (as a list of tex_strings)

• Return type: Self

_original__init__(*tex_strings, arg_separator=' ', substrings_to_isolate=None, tex_to_color_map=None, tex_environment='align*', **kwargs)

Initialize self. See help(type(self)) for accurate signature.

• Parameters:
  • tex_strings (str)
  • arg_separator (str)
  • substrings_to_isolate (Iterable *[*str ] | None)
  • tex_to_color_map (dict *[**str* *,* ParsableManimColor ] | None)
  • tex_environment (str | None)
  • kwargs (Any)

set_opacity_by_tex(tex, opacity=0.5, remaining_opacity=None, **kwargs)

Sets the opacity of the tex specified. If ‘remaining_opacity’ is specified, then the remaining tex will be set to that opacity.

• Parameters:
  • tex (str) – The tex to set the opacity of.
  • opacity (float) – Default 0.5. The opacity to set the tex to
  • remaining_opacity (float | None) – Default None. The opacity to set the remaining tex to. If None, then the remaining tex will not be changed
  • kwargs (Any)
• Return type: Self
