Add command line flags

[tommywei-cpu]

@13thsymphony is a very nice tool. Just wondering is it possible to make the software into an .exe file, so that I can call it in cmd, and with “-f” to specify a file name; “-t” to specify render effect; “-b” to specify brightness, and the default is to make the image fullscreen, with the UI being hide?

@tommywei-cpu, thanks for the suggestion!

Looks like we can add command line activation via: https://blogs.windows.com/windowsdeveloper/2017/07/05/command-line-activation-universal-windows-apps/#5YJUzjBoXCL4MhAe.97

But I'm not sure whether a UWP app can access arbitrary files, i.e. the UWP sandbox normally requires opening UI (the file picker), or manifesting for the restricted broadFileSystemAccesss capability which requires approval: https://docs.microsoft.com/en-us/windows/uwp/files/file-access-permissions

But, the command line option might also provide access to files within the invoked path: https://docs.microsoft.com/en-us/windows/uwp/launch-resume/console-uwp#uwp-console-app-behavior

An alternative is to register the viewer as the default file format handler for the file type you are interested in, and then invoke the file in a command prompt. That will launch the app. I can add persistent settings in the UI equivalent to -f -t -b. Would that work or do you need explicit invocation ability?

@13thsymphony Hey Simon, thanks for the reply. Register the viewer as the default seems a good idea. I just tried, and it can launch the APP automatically.

I think persistent setting is fine. The current default is "HDR tonemapp" and "100% brightness". Can you change the default to "No effect", with the UI being hidden and image being shown full-screen? I can change different tone mapping when generating HDR images.

@tommywei-cpu, I have a new version that supports command line invocation, version 1.0.6.0. It should be published to the store shortly.
