what do you mean precisely 🤔 ? You want to be able to show an image on the screen ? You want to be able to modify images ? 🤔

Actually no...

But if you want, I think it's possible to add to the kandinsky module in Python the possibility to draw an image, but it won't be transparent.

No I just mean to draw an image like a function draw_image(x,y,width,height) would be nice

Since you already have ulab with numpy arrays:

It'd be cool to have a way to blit an (w,h,3) array of RGB pixels onto the screen. It can be used to draw fixed "sprites", but given the efficiency of computations on arrays, it'd also become the highest-bandwidth way to draw computed graphics...
- Hmm, ulab doesn't support 3-dimentional arrays now? Well, take three 2-dimensional arrays.
It'd also be nice to have a function to read back a rectangle into ndarray.

I'm not sure how much RAM we have though. I can allocate np.zeros((200, 100), dtype=np.uint8) but (200, 200) already gives me "memory allocation failed"...
Still, any array ability would beat set_pixel loops 🐛

I sure think that would be a good idea if their were enough ram.
