Missing from B4XCanvas DrawPoint, I to overcome the obstacle I use DrawCircle and DrawLine, but I think they are slower and in any case it is not the best solution

If I remember correctly there is no "good" implementation for DrawPixel or SetPixel in B4i and maybe B4J as well.

You should learn about BitmapCreator as it is an excellent solution when you need to directly modify the pixels. You can combine it with B4XCanvas.

Do you think BitmapCreator can be faster than canvas?

BitmapCreator is very fast. Used correctly it can be much faster than canvas.

BitmapCreator is not a complete alternative to Canvas. In many cases you will want to use them together.

I can confirm, BitmapCreator is much faster than the B4XCanvas.
The only thing I have to use them both, because I use lines and rectangles that do not exist in bitmapCreator
