Tricky Hiding Input Information behind ImageJ API

[xp1632]

• When we get plugin Information from ImageJ API :

• For example, morphology.fillHoles:

• From OpInfo API, the requirement for input image is RandomAccessibleInterval

• which is a normal image type in IJ2

• we pass process_image with type RandomAccessibleInteral -and try to run this plugin : result_image= ij.op().run(morphology.fillHoles", ij.py.jargs(None,process_image,None))

• then we get error message as:

Indicating we need binary image as this plugin's Op, not regular RandomAccessibleInteral

---

How can I know if a op plugin has special type requirement not based on what its Info API said during batch node generation?

Solution:

• Omit the tricky optional parameters in ImageJ ops
• Use default value in mapping table if this optional parameter is really important
• After batch generation, we do a human intervention to keep the node robust
