I have lines (or segments really) I want to draw into a new image
Let's define the intensity of the pixel at
row = r and
col = c as
I(r,c). However, the lines are defined by 2 points whose coordinates are not integers.
For example, one line might be from point A (with
row = 2.2 and
col = 3.5) and to point B with (
row = 10.8 and
col = 30.4).
What is the algorithm or method for filling in the intensity values of image
I at the integer rows and cols?
