[Fxruby-users] Copying an Image with FXMemoryStream?

[Carsten E. <ca...@ci...>]

Hi,

I just can't figure out how this FXMemoryStream works. I just want to 
(deep) copy an image in memory:

  def copy_img(orig_img)
    dest_img = FXJPGImage.new(getApp(), nil, 
IMAGE_KEEP|IMAGE_SHMI|IMAGE_SHMP)
    data = ""
    FXMemoryStream.new { |stream|
      stream.open(data,FXStreamSave)
      orig_img.savePixels(stream)
    }
    FXMemoryStream.new { |stream|
      stream.open(data,FXStreamLoad)
      dest_img.loadPixels(stream)
    }
    dest_img.create
    dest_img
  end

But with this code I get this error:

test.rb:25:in `open': No matching function for overloaded 
'FXMemoryStream_open' (ArgumentError)
    from /home/careck/work/test/ruby/ScaleImageView/test.rb:25:in `copy_img'

What am I doing wrong?

Cheers,
Carsten.
