[REBOL] How to extend effects?
From: atruter::labyrinth::net::au at: 19-Mar-2003 9:28
Given the following:
<code>
REBOL []
img: to-image layout [origin 0 box 100x100 blue]
my-effect: func [face] [
repeat pos (face/size/x * face/size/y) [
poke face pos either odd? pos [255.255.255.0][0.0.0.0]
]
]
view layout [
image my-effect img
]
</code>
is it possible to simply have "view layout [image img effect [my-effect]]",
in essence extending the effects available to VID?
*If* this is possible, is it also possible to make the my-effect func
generic such that "view layout [box blue effect [my-effect]]" works?
If VID is a dialect, what are effects? Built-ins, properties, words? Are
they something that "belongs" to VID or View?
