@conejoninja please rebase against latest dev. Thanks!

Probably the first time I rebase locally, hope I didn't screw up.

That was perfect. 👍

(no rotation taken into account)

That seems is a possible issue, since most of the time with this screen we operate at 270 degrees rotation.

DrawBuffer is a new interface, why didn't you use the conventional DrawBitmap interface? (Or even DrawRGBBitmap8)

[conejoninja]

DrawBitmap already exists and it calls d.SetPixel for each pixel, but I already had the buffer with the data in the correct format, should should avoid a bunch of operations if just copy it instead. It's convenient (in my case)

Perhaps you would like to improve the implementation of DrawBitmap() instead? 😸

Not sure if possible or worthy.
Each byte of the buffer represent a row of 1x8 pixels. Using arbitrary coordinates x,y (ie not a multiple of 8), size and different rotations could be quite complex.
