view & multiply effect :-(
[1/7] from: max::quazart::com at: 20-Nov-2001 16:51
fellow rebolers,
why is it that everytime I try to use the multiply effect in view it just
doesn't work!
don't tell me there is a script called effect-lab which proves it works...
yes this script proves to me that I COULD eventually MAKE it work... which
just seems to rub in the fact that I can't get it work...
I've copied the 'supposed effect and it just doesn't work.... can anyone
give me any pointers?
please tell me what's wrong with:
rebol []
myLoadedImage: load %/path/to/image.png
f: make face [size: 300x300 offset: 30x30 ]
s: make face [
size: 100x100
offset: 100x100
color: red
image: anImage
edge: make
edge [size: 3x3 effect: 'bevel color 128.128.128]
effect: [multiply myLoadedImage]
]
f/pane: []
append f/pane s
view f
the sub-pane just gives me a red and black box
Thanks in advance for any help!

Hello myself :-)
hum...
no answers on the view mutliply problem... I guess not a lot of you are
doing fancifull view useage.... ah well...
was it my tone which might have sounded a tad frustrated? if so, its
completely unintentional. :-(
really, I'm just disapointed at my inability to handle this simple
multiply... just so you understand the context: Being a compositor by
trade, I have worked up to discreet inferno in the past (a U.S.$600,000
real-time film compositing software/system) and not being able to multiply
an image by another is quite an ego basher ;-)
I'm desparately trying to get Multiply to work in the effects block in order
to do some compositing for visuals in GLASS. I think I can use multiply to
simulate alpha channels in certain circumstances but I need multiply to work
correctly before...
Thanks :-)

Try
effect: reduce ['multiply myLoadedImage]

Holger,
it works :-)
It knew it was going to be simple. Its a question that in rebol, its
sometimes xtremely complicated to find that simple thing. There are so many
variations possible, that you can miss a few of them. :-)
thanks very much..

I spent quite a few hours trying to
simulate alpha channel effect using
multiply :)
I did not find a way.
We could do it if there was some way
to add two images using built in effects.
But I am not worried now since Holger has
implemented alpha channels for the next
release. :)
Anton.

Just two cents: did you try with:
effect: REDUCE ['multiply myLoadedImage]
(or with COMPOSE etc.).

Gabriele.
