Hello,
i just come back, and i will create a post on CPCTelera_next, to sum up all work done.
Yes, i have worked a lot on drawing line (here some video of work versions : https://www.youtube.com/@arnaudbouche7887). Thanks @ervin for his hard work on drawing lines, I picked up a lot of good ideas from his code.
Filling shape is in the todo list, you are welcome if you want to work on fillRect, fillCircle or fill what you want.
UPDATE : here the new post CPCteleraNext framework - #2 by Arnaud6128
