D8Viewer: How to open multiple images from the command line?

Help & Support
1

I have gone through the FAQ section for the viewer and also searched around, I have not found an answer.

I am looking to take multiple files, files not necessarily belonging to the same folder, and open them in a D8Viewer.

In PowerShell, $Input is a variable that has three files stored in it:

C:\Temp\Temp1\drawing.jpg
C:\Temp\Temp2\grey.jpg
C:\Temp\Temp3\orange.jpg

When I attempt to open the three files with the opus D8Viewer nothing happens:

D8Viewer $input

I am able to open the D8Viewer with this, but this is only with a single image file:

D8Viewer $input[1]

Oddly enough, when I have a D8Viewer window already open, invoking the following causes it to close:

D8Viewer $input

I have also tried the passing the files as quoted strings to the D8Viewer, nothing opens:

D8Viewer "C:\Temp\Temp1\drawing.jpg", "C:\Temp\Temp2\grey.jpg", "C:\Temp\Temp3\orange.jpg"

Only the following works:

D8Viewer "C:\Temp\Temp1\drawing.jpg"

By the way I tested the same variable against another image viewer, ImageGlass, all three files are opened:

ImageGlass $input

Thaks for any help.

I am afraid you'll need to call a script that grabs the files from $Input, adds them to a command object, and then runs Show on them.

I see, well I am willing to go down that route then.

Could you explain abit more, so I know where to get started? by a script, do you mean a script that is internal to Opus (written in JScript)? If so, how would such a script get an input from the command line?

I was not aware that internal opus scripts written by users can get external input in real time. If I have understood you correctly, that sounds promissing for many things.

Thanks!

I'd use a temporary file to hand over the list.

In Powershell, get a tmp file name:

$tmpFile = [System.IO.Path]::GetTempFileName()

Write the file list to the tmp file:

$Input | Out-File -FilePath $tmpFile

In Opus, write a script command that gets the tmp file from the command line. Run it from Powershell:

MyOpusShowCommand $tmpFile

In the script, adding the files to the command object is easy:

cmd.AddFilesFromFile(tmpFile);

Then launch the viewer:

cmd.RunCommand('Show');

To make the start a bit easier, you could use a hardcoded tmp file (e.g. C:\Temp\MyInputFileList.txt) instead of a dynamically generated one.

Aha! he speaks Powershell too!
This is very interesting and it seems simple enough. I will get started on it this weekend.

Just to be clear (so that I dont go assuming the wrong things), when you say:

Run it from Powershell

You mean via DopusRT right?

Thanks allot lxp!, this helps allot!
