100x100 The image comes in any reasonable format (e.g.
I'm using a simplified version of Bresenham's line algorithm for drawing lines. Lines will only have an integer slope so that the line will never partially cover a pixel but not color it:
At a minimum the line will be 3x3 unless the line is straight, in which case you will only see 3x1 or 1x3 in the image. Lines will also have one side on the edge of the image, so you only have to extend it in one direction.
