Source

Specifies an open TWAIN Source.

Return Values

Comments

The DTWAIN_IsExtImageInfoSupported function takes the open Source Source, and checks to see if Extended Image Information is supported. Extended image information allows an application to query barcode, imprinter, and other values of the TWAIN device that cannot be retrieved through normal capability negotiation. See Extended Image Imformation.

The source must be opened in State 4
