I'm using fxruby, so it looks like this for me:
# This should create a either very dark magenta or very bright
magenta, depending on internal bitcolors:
buf = 
buf << 255
buf << 0
buf << 255
transformed_buf = buf.join(" ") # Doesn't work
# transformed_buf = buf.pack("i") # Doesn't work either
image = FXImage.new(getApp(), transformed_buf, 0, 100, 100)
imageView = FXImageView.new(self, nil, nil, 0, LAYOUT_FILL_X|LAYOUT_FILL_Y)
imageView.image = image
All I get is a small, scrollable window in very dark grey.

Documentation for FXRuby says it should be FXMemoryBuffer or String. :(
FXMemoryBuffer doesn't work though:
fx_image_test.rb:20:in `new': allocator undefined for
And I can't figure out how to transform my Array to a proper String...

Sadly not, I'm using the Ruby interface...
But that's not your fault. :)
I don't know how/why my message ended up on the foxgui-users mailing
