FileInfoVirtualStack does not return the directory and filename

Yamada Hidenao
Hi, everyone, and hope everyone is safe.

I'm trying to get the directory or filename of the FileInfoVirtualStack by
using getDirectory or getFileName(n). However, these functions return
nulls. How can I get the full-path ?I think getDirectory() should return
info[0].directory like getWidth() in FileInfoVirtualStack.
---
FileInfo fi = new FileInfo();
...
FileInfoVirtualStack stack = new FileInfoVirtualStack(fi); // Opened a
stack image correctly.
IJ.showMessage("dir: " + stack.getDirectory()); // Error:
java.lang.NullPointerException
//IJ.showMessage("name: " + stack.getFileName()); //Error
java.lang.NullPointerException

This bug is fixed in the latest ImageJ daily build (1.52v20).

Hi, Wayne,

Thank you for updating for this bug.
I tried 1.52v and it works well in my plugin-filter for processing VirtualStack.

PS. I missed my credit in update lists in ImageJ News.

Best regards,
Hidenao Yamada
