No. A (0,0) ~ (10,10) square should be 10x10 pixel in my point of view as well. The top-left pixel is included in the square. > So, with 800x600 resolution: > 1) my point of view: it consists of 801 (0 ~ 800) points and 800 rods, > 601(0~601) points and 600 rods, along x/y axis respectively. > 2) your point of view: it has a coordinate ranges (0,0) ~ (799,599) > Both have the same number of pixel (squres) 800x600, OTOH. > What do you think? Did I correctly represent your view? So, do you study maths? :-) This gets too complicated for me for now. Still tired from the weekend. I will think this over, when my more of my remaining brain cells are working. For the time being, I'm satisfied with the cursor being over the center of the zoomed pixel.
