<br>
during my first attempts of implementing a ij2 plugin I realised that the following point is not clear to me:<br>
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<br>
<br>
@Parameter(type = ItemIO.INPUT)<br>
private ImgPlus<FloatType> img;<br>
or<br>
@Parameter(type = ItemIO.INPUT)<br>
private Dataset ds;<br>
<br>
but when running such code I get a warning-dialog saying; “An ImgPlus is required, but none exists”<br>
So I open an image and run the plugin again. The same dialog appears again.<br>
All the other types work well (String, File, etc.). Is this a bug or am I missing something.<br>
<br>
Best regards,<br>
<br>
Felix<br>
