TwainDSM is crashing

[Philip Gwyn Topics - 0Replies - 0Total Posts - 0]

I have a program in C# that accesses TwainDSM via twain-cs. I’m scanning with a Kodak i1440 scanner. When I scan 8.5×11 or 8.5×14 pages, it works fine and reliably. The i1440’s automatic page size detection. But when I scan a cashier coupon (long and skinny) my program simply crashes – no error message, no stack trace.

In twaindsm.log, the last message is as follows, which is pretty useless.

[125757452 dsm.cpp  2368     0 000015B4] Quaero Scanner Workstation -> KODAK Scanner: i1410/i1420/i1440

I have tried TWSX_NATIVE and TWSX_FILE with the same result.

More details : TwainDSM 2.4.2
Same problem happening with a fujitsu fi-6130Z
A scan with a custom size of 4.2×11 (inches) works
A scan with a custom size of 4.125×11 (inches) crashes.
