#### --braille OR -b
|

|

> **Note:** Braille pattern display heavily depends on which terminal or font you're using. In windows, try changing the font from command prompt properties if braille characters don't display
|
||||
|
||||
Use braille characters instead of ascii. For this flag, your terminal must support braille patters (UTF-8) properly. Otherwise, you may encounter problems with colored or even uncolored braille art.

|

#### --threshold
|
||||
|
||||
Set threshold value to compare for braille art when converting each pixel into a dot. Value must be between 0 and 255.
|
||||
|
||||
Example:
|
||||
```
|
||||
ascii-image-converter [image paths/urls] -b --threshold 170
|
||||
```
|
||||
|
||||
#### --dither
|
||||
|
||||
Apply dithering on image to make braille art more visible. Since braille dots can only be on or off, dithering images makes them more visible in braille art.
|
||||
|
||||
Example:
|
||||
```

||||
ascii-image-converter [image paths/urls] -b --dither
