Examples
open all close allScope (10)
Differently styled round rectangle edges:
Specify different rounding radii in the 
and 
directions:
Specify different rounding values for different corners:
Override both corners on the left side:
The effective radius used for any corner is limited to the half-length of each adjacent side:
For Framed, RoundingRadius->r always specifies the radius in absolute printer's points:
Use Scaled coordinates and Scaled rounding radius:
Use ImageScaled coordinates and ImageScaled rounding radius:
