strange imagedata

[Björnke von Gierke]

You are setting the imagedata to null, which is equivalent to 0 which is equivalent (at least for the imagedata) to 0000 which is equivalent to black. At least i'd assume something like that is happening. I suggest you file a bug report.


Try the following to set an image to a state where it shows nothing:

put "" into image 1
