Here are a couple of simple examples to demonstrate:
The first example is device=gif Proc Gmap output. If you look very closely, you'll notice that the borders of the states have a slight jagged/stair-step appearance in the 9.3 output, whereas the 9.4 output has smooth lines:
And even though you could get device=png smooth-line graphs in SAS 9.3, you could not use device=png for animations. And gif animations did not support smooth anti-aliased lines in SAS 9.3. Therefore it is great new functionality for SAS 9.4 gif animations to support smooth lines! See the difference in the examples below -- The 9.4 output has smooth lines in both the state borders and the circular marker:
And here's a link to a slightly fancier gif animation (originally written by Richard DeVenezia, and which I slightly modified to use the SAS 9.4 smooth lines) ... hope you enjoy!
Feel free to leave a comment describing how you might use this new SAS 9.4 feature!
