Re: [pygame] Time to load font with pygame.font.SysFont on Mac
Hi, There probably should be an open issue for this. The initial query is quite slow unfortunately, and I can’t find a quicker query. What can be done is to use a known set of fonts for different or some subset of OS versions... Apple did/does publish these lists somewhere, so a fix would be to first look at these lists and then only query if the font can not be found. For many/most fonts that people use with SysFont (like Arial) this would hit the fast path and avoid this slow query. cheers, On Sunday, April 4, 2021, Greg Ewing wrote: > On 5/04/21 9:29 am, Irv Kalb wrote: > >> If I load a font like the system font using None with a call to >> pygame.font.font, it happens almost immediately. >> >> But if I load a font by name using pygame.font.SysFont, it's taking over >> 7 seconds on my Mac to load.

Re: [pygame] Time to load font with pygame.font.SysFont on Mac
If I remember correctly, there's a external call to fc-list that is very
slow. At one time, I intended to improve this situation by removing the
fc-list dependency on Mac and Linux and instead collecting only the needed
font data by using freetype and/or Mike C. Fletcher's TTFQuery, but I got
too busy.

[pygame] Time to load font with pygame.font.SysFont on Mac
[I apologize if this is a duplicate, but I haven't seen this message show up on
the list.]
I have tracked down a huge slowdown on loading fonts with pygame.font.SysFont
Mac OSX 11.2.3
Python 3.9.1
Pygame 2.0.1
If I load a font like the system font using None with a call to
pygame.font.font, it happens almost immediately.
But if I load a font by name using pygame.font.SysFont, it's taking over 7
seconds on my Mac to load. It doesn't seem to matter which font I try to use.
Sample program:
import sys
import pygame
import time
pygame.init()
screen = pygame.display.set_mode((400, 400))
clock = pygame.time.Clock()
now = time.time()
font1 = pygame.font.Font(None, 24)
print('Loading System font took', time.time() - now)
now = time.time()
font2 = pygame.font.SysFont('Arial', 24)
print('Loading Arial font took', time.time() - now)
while True:
for event in pygame.event.get():
if event.type == pygame.QUIT:
pygame.quit()
sys.exit()
screen.fill((255, 255, 255))
pygame.display.flip()
clock.tick(30)
Output:
pygame 2.0.1 (SDL 2.0.14, Python 3.9.1)
Hello from the pygame community. https://www.pygame.org/contribute.html
Loading System font took 0.0006210803985595703
Loading Arial font took 7.058471202850342
(I don't have a setup to test this on Windows.)
This seems like a rather excessive amount of time as it slows down that start
up of many of my programs.
It seems to be related to how long it takes to get the list of fonts. If I add
this before the call to SysFont:
now = time.time()
fontList = pygame.font.get_fonts()
print('Getting fonts took', time.time() - now)
I get:
Loading System font took 0.0006549358367919922
Getting fonts took 7.013390064239502
Loading Arial font took 0.0004830360412597656
Anyone else seeing this?
Can someone tell me how to send in a bug report for this?
Thanks,
Irv
