Hi
during my first attempts of implementing a ij2 plugin I realised that the
following point is not clear to me:
thanks to the widget demo of the imagej-tutorials I managed to define my UI in
the ij2-way. Now during my further research to find a way to easily define an
image input and getting the dialog with the Parameter decorator I found
examples like
@Parameter(type = ItemIO.INPUT)
private ImgPlus<FloatType> img;
or
@Parameter(type = ItemIO.INPUT)
private Dataset ds;
but when running such code I get a warning-dialog saying; “An ImgPlus is
required, but none exists”
So I open an image and run the plugin again. The same dialog appears again.
All the other types work well (String, File, etc.). Is this a bug or am I
missing something.
Best regards,
Felix
