That's not really my problem. I'm
talking about the extra spacing
added above and below the font when it is rendered. Take a look at the
attached screenshot. I render the text "Xj()~'" in the upper-left
corner at position (0,0), with a height of 24. The text is drawn 54
pixels in height, but font.size() returns (46,35), resulting in my font
being drawn 9 pixels below the desired positon. Drawing a larger font
results in the font being drawn even lower
Here are some other results:
| Desired |
size[1] |
True Pixel |
| 8 |
6 |
12 |
| 16 |
14 |
23 |
| 20 |

74 |
112 |
| 100 |

Desired = Height value passed to Font constructor
size[1] = height value in tuple returned by font.size()
True Pixel = True height of the rendered font in pixels
The true pixel sizes seem predictable at least, they seem to be desired
height * 1.4 rounded up... So I would guess there is some kind of
(fairly) simple model that makes sense...
Could you send the font you are getting the numbers for that table
with? and maybe send a small sample showing the problem?

text = "Hello world!"
name = "arial"
bold = False
italic = False
height = 24
font = pygame.font.Font(pygame.font.match_font(name, bold, italic),
height)
size = self.pgFont.size(text) # returns (46,35)
surface = font.pgFont.render(text, False, (255,0,0,255))
The top 9 rows of pixels in the surface returned by render() are all
black.
The height values vary for different fonts (verdana, courier, times,
system), but there is always a band of empty space above the text.
The only solution I can think of is to come up with some formula to
determine the number of pixels to move the text rendering up. It seems
as though the formula would be different for each font, though.
