I discovered a problem with CGShadings on Tiger: If I draw a
horizontal shading (i.e. the y-coordinates of start and end point
are equal) and the red component of both the start and end points
is equal to 1.0, the shading will be opaque (alpha values for both
start and end point will be ignored).
If I change the red component for one of the points to a value less
than 1.0, or change the y-coordinate of one of the points, the
shading draws as expected. Here is the code:
< code sample snipped>
Am I doing something wrong or is this bug already known?
I believe that somebody posted a variation on this problem to this
list before. Neverthless, you should write it up with examples and
put it in bugreport.apple.com.
