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
