Slow scanning mode - fragile documents #16

Closed petrjac closed 3 years ago

petrjac commented 3 years ago

Please, is it implemented mode for slow scanning?

I have successfully tried to sendTask and and bridge (with connected Alaris S2070) returned:

...
{
  "attribute": "sheetHandling",
  "values": [
    {
      "value": "fragile"
    }
  ]
},
...

But it seems to have no effect on scanning speed.

The Bridge turns the fragile request into: "CAP_PAPERHANDLING,TWON_ONEVALUE,TWTY_UINT16,1", where the value 1 is FRAGLE. Looking at the S2000 driver I see that's not being mapped to anything. CAP_PAPERHANDLING is only reporting support for NORMAL. So, sadly, that's an issue for that particular scanner driver.

I'm closing this because it's not a TWAIN Direct issue...
