      I am using M5 CoreInk. To my understanding, it is possible to display images, using spite.drawBuff(x, y, width, height, imageBuf); where we supply the image as an array of unsigned char (0x00 for black, 0xff for white).

      There is an example of such arrays here.

      My question is the following: how were those arrays created? is there a tool/script/command line to convert ASCII art, or BMP, or PNG, or JPG (whatever) to this table?

      Thanks
