Hit testing of lines/paths can basically be done in two ways:
a) mathematically, in that you determine whether a given point is close to a
given line by calculation
b) graphically, in that you draw the line into some image and test the pixel
drawn.
I've done quite a bit of work on this in the p
It seems to me that a simpler way to do this would be:
- get the endpoints of the line
- figure out the slope of the line
- If the slope is <= 1, pull out the x coordinate of the test point. If the
slope is > 1, use the y coordinate of the test point
- using the algebra that you learned when you
Hi all,
I searched back through 2005 in the Cocoa Mailing List and didn't see any
requests for this.
We need all the points on a line / arc / path on the screen. We need to do hit
detection on stroked line, so we must know if the point is valid or not.
I thought using CGPathContainsPoint woul
