Allocate a static buffer for 1bpp/2bpp/4bpp greyscale sprites and draw bitmaps on it about lovyangfx HOT 6 CLOSED

I understand exactly what you mean, and I was originally going to implement it as well.
However, if you implement it, the template will become larger and the binary size will become huge. I believe this implementation was a failure.

I actually have quite a few problems with the current LovyanGFX V1 implementation, and am considering creating a new V2 design from HAL. So we don't want to spend time supporting V1.

Just add a function prototype like this. I think it takes just a few bytes. However, most of projects do not use this prototype.

By the way, if you copy an RGB565 image to a palette image, what kind of result do you expect to get?
If I were to implement this, I would simply allocate the low byte of the bit string.
If you want to automatically select a palette that reproduces the colors of the original image, that would require a fairly tedious implementation.

It is not easy to copy a normal image like RGB565, RGB888 etc to a palette image. But it is easier to copy to a 1bpp/2bpp/4bpp greyscale image.

I will create my own transform function if I must copy from an normal image to a palette image.

So, I just hope to add a prototype for creating a static sprite. You do not need to do anything else for V1.

    void setBuffer(void* buffer, int32_t w, int32_t h, color_depth_t bpp = rgb565_2Byte);

Use this setBuffer function, I'll create a static sprite with any color_depth_t.
