The image! datatype takes the following form:
make image! [size data]
The size is, of course, a pair!, eg. 240x180 and the data is binary!.
img: make image! [2x2 #{0000CC0000CC0000CC0000CC}]
The data equates to colours similar to web hex values, except the order is
BBGGRR. So the above example would give you 4 red pixels (B = 00 or 0, G 00 or 0 and
R = CC or 204).
To load external image data, use 'load or 'load-image (the latter caches
images from the web/reb):
img: load-image http://www.ross-gill.com/r/rg-rim.png
probe img
To put the image into the clipboard in REBOL format,
save clipboard:// img
Hope that's enough to get you started.
