Hi all
Iam wrapping twain32.dll via VB.NET 2003
I need help how to calculated DPI that supported by scanner device.
I used Canoscan N650u
I have already get value from YRESOLUTION and XRESOLUTION, and get XRESOLUTION value below :
Default : 75
MaxValue:9600
MinValue:25
and YRESOLUTION value below:
Default : 75
MaxValue:9600
MinValue:25
but on CanoScan application DPI only supported between 75DPI to 1200DPI. So i need help how to list DPI that supported by scanner device.
Thanks
