Dear Nick,
Thank you for your query and for submitting it here in the public forum.
I am sorry to say that do not currently see any API access to this functionality.
Surprisingly for me, I could not find a wish list item for it either.
I therefore submitted the wish list item CF-4292 [API wish: access Image Export Options] on your behalf for the functionality you suggest, as this issue requires exploration and possibly a modification to our software. Please make a note of this number for future reference.
You are welcome to request an update on the status of this issue or to provide us with additional information at any time quoting this wish list item number.
This issue is important to me. What can I do to help?
This issue needs to be assessed by our engineering team, and prioritised against all of the other outstanding change requests. Any information that you can provide to influence this assessment will help. Please provide the following where possible:
- Impact on your application and/or your development.
- The number of users affected.
- The potential revenue impact to you.
- The potential revenue impact to Autodesk.
- Realistic timescale over which a fix would help you.
- In the case of a request for a new feature or a feature enhancement, please also provide detailed Use cases for the workflows that this change would address.
This information is extremely important. Our engineering team have limited resources, and so must focus their efforts on the highest impact items. We do understand that this will cause you delays and affect your development planning, and we appreciate your cooperation and patience.
You may also want to take a look at this related thread discussing 'preview image for a family, set anti-aliasing, set model edges to on':

It ends with a suggestion from Revitalizer to make use of the Windows API and/or UIAutomation functionality to programmatically set the Revit UI thin lines.
We published his solution for setting thin lines on The Building Coder:

That is almost certainly possible, probably quite reliable, and not that hard to do to access to the five Export Image Options toggle buttons that you highlighted in your image as well.
I hope this helps.
Please let us know how it goes.
It would be cool and a pleasure for me to present a solution for this using the Windows API.
Thank you!
Best regards,
Jeremy
