TransferMode file isBlankPage

Post by marcmoennikes » Tue Jun 28, 2011 2:36 pm

Hello,

is the "isBlank" Method also with transferMode.file supported?

I have used the "TwinFileTransferDemo" with some changes.
Now i want to detect blank pages. The trnasfermode is at the moment "file".
with memory mode it is working in another test project.
Is there an example for file mode with blank page detection?

thank you

Regards

Hello,

You can apply image processing functions of VintaSoftTwain.NET SDK only for images from the internal image buffer of SDK.

SDK adds acquired image to internal image buffer only if Native or Memory transfer mode is used, SDK saves acquired image directly to file if File transfer mode is used.

You can use VintaSoftImaging.NET SDK (IsImageBlankCommand command) if you want to detect blank pages in image files.

Best regards, Alexander
