Rebol Draw: how to load image from the internet ?

Question

This works

view layout [
    image load http://i2.ytimg.com/vi/e3wShd_bX8A/default.jpg
]

But this doesn't

view layout [box 100x100 effect [draw [
        image load http://i2.ytimg.com/vi/e3wShd_bX8A/default.jpg
    ]
]

Answer 1

LOAD is not part of the EFFECT or DRAW dialects, so it is being ignored.

You can use COMPOSE to ensure it gets executed:

view layout [
    box 100x100 effect compose/deep [
        draw  [
        image (load http://i2.ytimg.com/vi/e3wShd_bX8A/default.jpg)
        ]
    ]

]

Notes:

• COMPOSE/DEEP because we are two deep in blocks -- effect [draw [ ... ]]

• the "native" REBOL code that you want executed is in parenthesis: (load ...)
