# Font bounding box and character bounding box
BDF font file has a font bounding box (FONTBOUNDINGBOX).
This means that there is a 3 pixel margin to the left of the all font, and a 6 pixel margin below the all font.
This FONTBOUNDINGBOX value indicates that there is a 3 pixel margin to the left of the all font, and a 6 pixel margin below the all font.
```
FONTBOUNDINGBOX 21 26 -3 -6
```
Each character has a character bounding box (BBX).
This BBX value indicates that it should be moved one pixel to the right when displayed.
By providing a character bounding box (BBX), this can omit the leftmost blank space.
Each character has a character-specific bounding box (BBX).
This BBX value indicates that there should be a 1 pixel margin to the left of this character.
By providing a character-specific bounding box (BBX), this can omit the leftmost blank space.
