in my use, I’ll ask for the available pixel types and I get an enum. From there I’ll set with a onevalue. using oneValue or enum in the set depends somewhat on your intended use, are you trying to set to a value (use oneVal) or limit the user’s chose to a format you support (use enum) – least that’s how I read the spec,
Thanks for your reply. I am not trying to set the value, nor am I trying to limit the user’s choices. I let the scanner driver’s interface handle the scanning. When the scan process is complete and I need to retrieve the results. I am trying to get the current settings so I know what I am retrieving.
The problem is that I recently discovered I need to support the enum container type. I am trying to locate a scanner in-house that I can test with. All appear to use one-value, but I am wondering if changing their scan settings (using the scanner driver’s scan interface) might cause them to use enum.
