[sane-devel] SANE_FRAME_IR

[Ulf Zibis]

Interesting stuff.

because of that missing part I have to use the commercial VueScan for my slide scanner.

What about to use the SANE_FRAME_IR option for backends which support it and deliver a separate IR frame as grey for others?

I assume that this was a proposed extension at some point. However, this would mean we would need to ratify a new standard and ask frontend developers to support the new features, something that we might struggle to do ourselves what with the backlog we currently have.
