LWIACAPABILITY

Summary

The LWIACAPABILITY structure provides information about each enumerated WIA capability.

Syntax

typedef struct _LWIACAPABILITY 
{ 
   L_UINT  uStructSize; 
   L_UINT  uPropertyID; 
   L_TCHAR szPropertyName[MAX_PATH]; 
   L_UINT  uVariableType; 
   L_UINT  uPropertyAttributes; 
   pLWIACAPABILITYVALUES  pCapabilityValues; 
} LWIACAPABILITY,   * pLWIACAPABILITY; 

Members

uStructSize

Size of this structure in bytes, for versioning. Use the sizeof() operator to calculate this value.

uPropertyID

The enumerated property ID.

szPropertyName

The name of the enumerated property.

uVariableType

The type of the enumerated property so the property can be cast correctly for the received property value.

uPropertyAttributes

Enumerated property attributes, including the property value type (Flag value, List value, or Range value); and property access (Read, Write, Read/Write).

The following constants are valid property attributes:

pCapabilityValues

Pointer to the values structure that contains the enumerated capability values.

Comments

This feature is available in LEADTOOLS version 16 or higher.

pLWIACAPABILITY is a pointer to an LWIACAPABILITY structure. If the function parameter type is LWIACAPABILITY, declare an LWIACAPABILITY variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pLWIACAPABILITY variable is necessary only if your program requires a pointer.
