setBorderColor = "[color] start, [color] end, [int] curve" [color] is a 6 digit hexadecimal value [int] is an integer value, -2,147,483,648 to 2,147,483,647
Examples
In this example we will be using a button widget
.. setBorderColor="FF0000,FFFFFF,0" ..
it reads as;
Starting from the color red (FF0000)
to the highlight color of white (FFFFFF),
while using the linear curve to render the border (0)
Let's use a concave transformation to render the border and look at the difference
.. setBorderColor="FF0000,FFFFFF,1" ..
Starting from the color red (FF0000)
to the highlight color of white (FFFFFF),
while using the concave curve to render the border (1)
Let's use a convex transformation to render the border and look at the difference
.. setBorderColor="FF0000,FFFFFF,2" ..
Starting from the color red (FF0000)
to the highlight color of white (FFFFFF),
while using the convex curve to render the border (2)
Notes
For the softest curves use a convex curve transformation.
This works particularly well on light backgrounds, since most of the transistioning colors
gets pushed to lighter end of the spectrum thus blending with the background
