With the line tool I draw a line on an image.
Then I get coordinates of points along the line using this code:
getLine(x1, y1, x2, y2, lineWidth);
Now I want to do the same but instead of drawing a line I have input 2 points and have recorded their coordinates, (x1,y1) and (x2,y2).
I could use a loop and calculate the in-between coordinates using trivial trigonometry but I’d be surprised if there wasn’t a specific function to do more efficiently.
