DTWAIN_IsFeederEnabled

The DTWAIN_IsFeederEnabled function checks if the document feeder has been enabled for acquiring images.

DTWAIN_BOOL DTWAIN_IsFeederEnabled ( DTWAIN_SOURCE Source );

Parameters

Source

Specifies an open TWAIN Source.

Return Values

If the automatic document feeder has been enabled, TRUE is returned.  Otherwise FALSE is returned.

Comments

The DTWAIN_IsFeederEnabled function takes the open Source Source, and checks to see if the document feeder has been enabled for acquiring images.  If the return value is TRUE, the document feeder will be used to acquire image(s) from the device.  If the return value is FALSE, the alternate input path is used (usually this is the flatbed portion of a scanner device).  If the device does not have a document feeder, the return value will always be FALSE

TWAIN State Transitions

The source must be opened in State 4
