Images passed as command line arguments are never shown

[ctrueden]

From Thorsten Wagner on the ImageJ mailing list:

The command

imagej /home/thorsten/data.jpg

opens the image data.jpg.

However, when I use fiji, the command

./ImageJ-linux64 /home/thorsten/data.jpg

does nothing.

The issue is: while the ImagePlus gets created and populated, it never appears on screen because the ImageJ 1.x main window has not yet been shown. This is a consequence of ImageJ2 processing command line arguments before displaying the user interface.

There are probably several viable ways to work around this problem.

Until this bug is fixed, one way to work around this issue is to use the --open flag; e.g.:

./ImageJ-linux64 --open /home/thorsten/data.jpg

Indeed, I cannot reproduce this bug anymore. The commit that probably fixed it for --open (assuming it was even broken) is scijava/scijava-common@c53149e. The behavior when passing the filename directly is different, and handled by ImageJ 1.x, but the image did appear in my tests.
