I see - that’s something we are also actively working on - but for us, image acquisition time isn’t really the bottleneck. We acquire a Z stack at each XY location, so most of the time is spent autofocusing and moving the stage. @JohemianKnapsody has done some nice work optimising the Z stacking and autofocusing procedure, and we’re in the progress of putting this together as a plugin and manuscript. It should work in the latest version of the server - but it’s not been tested much yet.
I guess you would want to be integrating the acquisition with moving the microscope slide? If so, it would probably be possible to do this by creating a custom version of the scan plugin - you could override the code that does image capturing with a faster method (e.g. using a “generator”). However, as most of the time is spent moving the stage, I suspect you are unlikely to go much faster than using the exsting plugin but requesting it to use the “video port” on the camera, which saves a fraction of a second per image.
I’ve just checked, and there’s no tick-box for that in the software, though it is possible to access it through the “swagger” client. I’ve recently started a push to document that interface a bit better, you can see the current attempt though I’ve not yet got as far as improving the documentation for the scan plugin.
