--------------start of code------------------------
site: http://www.rebol.cz/~cyphre/
x: 0
d: 5
view layout [
origin 0x0
image load-thru/binary site/city.jpg 320x240
at 0x0
image load-thru/binary site/bay.jpg 320x240 with [
rate: 30
effect: compose [fit alphamul (x)]
feel: make feel [
engage: func [f a e][
x: x + d
if x > 250 [d: -5]
if x < 5 [d: 5]
f/effect: compose [fit alphamul (x)]
show f
]

Subject: [REBOL] alpha image blending...
hi,
a while ago a friend of mine told me that the latest versions of view
support 8bit alpha channels properly in order to blend images with their own
transparency...
Is this still true, and if so, can anyone show me a simple example:
something as siple as:
imageA: load %imgfileA
imageB: load %imgfileB
imageC: imageA/rgb over imageB/rgb using imageA/alpha
view layout [box imageC imageC/size]
Thanks in advance !
