Hi,

I can't find any information on this Does .NET version of Leadtools 14.5 support GetExtImageInfo?
In the example I got in this forum is about RasterTwain.GetExtImageInfo().

Thanks for your kind attention,
Raymond

Hi,

I browsed the help file in "Getting Started with Leadtools" for v15,
it states that

"get the Extended Image Info that some TWAIN scanner drivers support"

Does it mean v15 can do this? Is it available in .NET v15?

Thanks,
Raymond

Hello,

The TwainSession.Acquire method acquires one or more images from a TWAIN source. If the user has overridden the AcquirePage event, the AcquirePage event will receive each image acquired from the source. This allows the user to process each image as desired, when the user acquires an image, the TwainAcquirePageEventArgs.Image property is updated with the acquired image.
Within the AcquirePage event the user can call the UpdateExtraImageInformation method to get extended image information that is included if the TWAIN source is a barcode reader or a digital camera.

Thanks,
Maen Badwan
