There is some discussion here about fill-pen http://www.mail-archive.com/rebol-bounce@rebol.com/msg02019.html
But I can't see documentation about cubic, diamond, etc... effect for fill-pen in rebol's official doc ?
I'm trying to draw some round rectangle with glowing effect but don't really understand the parameters I'm playing with so I can't get exactly what I'd like (I'd like the glow effect starting from the center not from the dark left top corner):
view layout [
box 278x185 effect [ ; default box face s开发者_如何转开发ize 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 is a little complex:
;fill-pen 10x10 0 90 0 1 1 0.0.0 255.0.0 255.0.255
fill-pen radial 20x20 5 55 5 5 10 0.0.0 55.0.5 55.0.5
; the draw element
box ; another box drawn as an effect
15 ; size of rounding in pixels
0x0 ; upper left corner
278x170 ; lower right corner
]
]
]
Finally I made it so not sure how I did manage to get :)
