This code might be really cool for animated banners but QBJS is messing up code working fine in QB64.

Have a look:
Code: (Select All)
'Option _Explicit
'_Title "Font From String Patterns Strokes" ' b+ 2023-08-27
' Inspired by grymmjack post here https://staging.qb64phoenix.com/showthread...0#pid18990
' I used his font patterns to get my version started

' 2023-08-29 fixed with -1's in steps

' 2023-08-29 Now with numbered strokes for drawing
' and grymmjack's fix for character design

' 2023-08-30 attempting to get this working in QBJS, it would be nice part of Banner printing!

Well, I figured out how to fix it.  If you add 1 to line 47 it works as expected.  I don't know why this is the case but I suspect it has something to do with a rounding issue.

Dang that disables the QB64 code!

i = (r * sq) + c + 1 ' All these are integers already so i is integer already

Does QBJS ignore integer types?
b = b + ...

Ha, if we do this it should work in both:



(I'll save this example though and try to find out if there is something I need to fix with QBJS.)
