Discussion - EVE / Re: Eve3 built-in fontset
« on: May 01, 2024, 08:43:02 PM »
I played some more with ESE and these might be the font sizes:
#26 -> 15
#27 -> 17
#28 -> 21
#29 -> 24
#30 -> 31
#31 -> 42
#32 -> 55
#33 -> 70
#34 -> 94
The BT817/8 datasheet states though:
"Fonts 31-34 are large ROM fonts encoded in ASTC 8x8 format."
And:
"Using ASTC for the large ROM fonts can save considerable space. Encoding the four largest fonts in
ASTC 8x8 formats gives no noticeable loss in quality and reduces the ROM size from 1 Mbytes to
about 640 Kbytes."
So at least these four should have been converted later for the BT817, like 2019?
Knowing the the original settings for the font conversion probably is not enough?
At least I am not seeing a dithering option with "eab_tools.exe font -h" in EAB 2.11.0
