Another experiment with pygame's font API. Looks very strange.
Printed out the width (in pixels, presumably) of a string of 100 letter
'x' rendered at different point sizes.
Now FreeMono is 1000 units high and 600 wide.
The point size is the height, and a point is 72 pt/in.
My screen's x-resolution is 125 DPI (from /var/log/Xorg.0.log)
s =
"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
for fontsize in range( 5, 25 ):
m = pygame.font.SysFont("FreeMono", fontsize)
print "(", fontsize, "pt) ", m.render(s, False, (0,0,0)).get_size()[0]
I would expect a number more like 1042px at 10 pt:
100 * 10 pt high * (0.6 FreeMono width/height) * (125 px/in ) / (72 pt/in)
But see below.
Totally don't understand the numbers I get.
I also looked at the "height" measure returned by get_size()... it gives at 10
pt
13
while
10 pt * (119 px/in Y-DPI) / (72 pt/in) = 16.52 px
These units are not pixels, I guess. I wonder what they are.
This and, maybe my arithmetic isn't right.
Widths of 100 x's at a range of point sizes.
