Using braces #941
Comments
|
Have you installed LaTeX? You also need quite a few LaTeX packages with it as well. |
|
I certainly have. This is the basic LaTeX code, I just wanna write the braces separately. Here the traceback: Thanks! |

Hmm, the traceback points to a log file in `./media\Tex\0447ed74899f41fb.log`. Could you please post the contents of that as well?
Also, I've heard people saying that it isn't possible to write a single brace in LaTeX. You use Brace() for that, but you say you have tried that as well.
In any case, the contents of the log file would be mighty helpful.

This appears to be a LaTeX specific problem. You simply cannot use a single brace separately in LaTeX, and the way manim renders LaTeX (it uses \align a lot), the parser keeps thinking it is seeing a single brace. For the time being, i suggest you use two Brace()es, which is tedious, but perhaps someone more experienced with LaTeX can help you out. If you feel like probing the problem deeper, you can modify tex_template.tex, and see if you can get it to work. All the best ;) |

in LaTeX you can't use a single curly bracket. <?xml version="1.0" encoding="utf-8"?>

I was able to use single curly brace in single line with custom color using Brace() and dummy text. See if this helps you |
…eeDAxes' (3b1b#941) As described in 3b1bgh-940, there is no direct way of setting the x-axis and y-axis limits through the 'ThreeDAxes' constructor. This commit adds 'x_min', 'x_max', 'y_min' and 'y_max' as parameters to the constructor of 'ThreeDAxes' to let the user explicitly pass those limits.
I'd like to run the code:
numeros4 = TexMobject( "\\mathbb{N}", "=", "\\{", "1", ",", "2", ",", "3", ",", "\\ldots", "\\}" )cause I wish I could change the color of the braces separately. But I got this error:
Exception: Latex error converting to dvi.I've already tried using the command
Brace()or the ideas found at reddit, but it didn't work at all. Is there a way to make it possible?Thanks!
