Solution found!
The option disable_ligatures
must be set to True
when creating the Text mobject. So the example in the issue must be modified to
from manim import *
class Test(Scene):
def construct(self):
TxExample = Text("This example contains white spaces", color=WHITE, disable_ligatures=True).scale_in_place(0.8)
TxExample.set_color_by_t2c({"This": GREEN})
TxExample.set_color_by_t2c({"example": RED})
TxExample.set_color_by_t2c({"contains": BLUE})
TxExample.set_color_by_t2c({"white": GOLD})
self.add(TxExample)
It's expected behaviour when ligatures are ON. Also, you can use MarkupText
and use markup like HTML which you can use to colour text and don't need to turn off ligatures.
Hope you found the solution. Closing this issue.
Description of bug / unexpected behavior
(using ManimCE_v0.7.0)
When using the internal function
set_color_by_t2c(t2c={word:color})
on an mobject.svg.text_mobject (created withText("mystring")
), the coloring of the string is sometimes shifted. When running some researches and tests, I am almost certain that it badly accounts for blanck spaces when calculating the index at which the word to color starts and end (done by the internal functionself.find_indexes(word, self.original_text)
). This results in a single positif shift of the index of the word to color for each previous blank spaces present in the string (see example and image below).Expected behavior
The coloring should correspond to the word passed by in the dictionary
{word:color}
How to reproduce the issue
Code for reproducing the problem
```py from manim import * class Test(Scene): def construct(self): TxExample = Text("This example contains white spaces", color=WHITE).scale_in_place(0.8) TxExample.set_color_by_t2c({"This": GREEN}) TxExample.set_color_by_t2c({"example": RED}) TxExample.set_color_by_t2c({"contains": BLUE}) TxExample.set_color_by_t2c({"white": GOLD}) self.add(TxExample) ```Additional media files
