Anti-alias works for Draw but I can't see how to get anti-alias for font : is it possible anywhow (including hacking rebol vid ...) because font in the picture generated below is not nice:
view layout [
box 278x185 effect [ ; default box face size is 100x100
draw [
anti-alias on
; information for the next draw element (not required)
line-width 2.5 ; number of pixels in width of the border
pen black ; color of the edge of the next draw element
fill-pen radial 100x50 5 55 5 10 10 71.0.6 30.10.10 71.0.6
; the draw element
box ; another box drawn as an effect
15 ; size of rounding in pixels
0x0 ; upper left corner
278x170 ; lower right corner
]
]
pad 30x-150
Text "Experiment" font [name: "Impact" size: 24 color: white]
