Hello everybody,

When i scan from an 64 bit application with WIA driver
i can see that WIA 64 bit driver start a 32 bit subtask
which with WIA 32 bit driver make the scan and after return image to main task.

So Even Microsoft recognize that scanner manufacturers don't often provide 64
bit drivers and use this strategy  as workaround.

So i continue to think that for 64 bit LO the only solutions are:

1) when select source select only WIA mode and ignore TWAIN

2) start a 32 bit subtask which use  32 bits LO scan code and return obtained
image to main task

Best regards

this should be Windows only, TWAIN would remain viable for macOS and Linux

--- Comment #3 from V Stuart Foote  ---
64-bit TWAIN 2.3 drivers for Windows are not widely implemented. While we've
added support to use TWAINDSM.DLL 64-bit driver [1]--in practice we have no
Scan support for 64-bit Windows builds.

Implementing support for 64-bit WIA framework would allow use of widely
available 64-bit scanner drivers. [2]

32-bit TWAIN drivers remain common, but providing 32-bit WIA should probably be
implemented as well. WIA is stable enough on Windows that TWAIN could be
deprecated.
