Hi
I am upgrading an application from version 5 which scans one or more pages as pdf to a database using javascript. It is working fine for single pages but when scanning more than one page I receive an error 'wrong number of arguments or invalid property assignment' on the line
device.AcquiredImages.Last.Save(mem, 5);
here is the code:
do
{
acquireState = device.AcquireModal();
if (acquireState == 2) // image acquired
{
iCount++;
// save all acquired images as PDF stored in the memory
if (firstImage)
{
// get the first image as PDF stored in memory
mem = device.AcquiredImages.Last.GetAsStream(5);
firstImage = false;
}
else
{
// add image to PDF stored in the memory
device.AcquiredImages.Last.Save(mem, 5);
}
}
}while (acquireState != 0);

Re: Saving multiple page pdf to database
Hello,
JavaScript does not support function overloading.
Today version 7.0.2.1 of VintaSoftTwain.NET SDK is released - we have added the AcquiredImage.SaveToStream(Stream, ImageFileFormat) method with the same functionality as AcquiredImage.Save(Stream, ImageFileFormat) method.
Best regards, Alexander
