TWAIN & WIA

This demo illustrates how to use GdPicture.NET to control your scanners using the TWAIN acquisition protocol. It gives you the ability to select your scanning source, manipulate the brightness and the contrast, and setup your source options. You can scan to PDF, multipage TIFF, JPEG, as well as scan all the documents in the feeder to either JPEG files or a multipage PDF documents.

Like the Twain Scanning demo, this one illustrates how to use GdPicture.NET to control your scanners using the TWAIN protocol. The only difference is that this demo does it asynchronously.

This demo illustrates how to use GdPicture.NET to control your scanners using the WIA Protocol. It gives you the ability to select your scanning source and some image processing techniques like rotation, hole punch removal, black border removal, and auto de-skew. You can scan to PDF, multipage TIFF, JPEG, as well as scan all the documents in the feeder to either JPEG files or a multipage PDF documents.
