LWIACAPRANGEVALUES

typedef struct _LWIACAPRANGEVALUES 
{ 
   L_UINT uStructSize; 
   L_INT nCapRangeMinValue; 
   L_INT nCapRangeMaxValue; 
   L_INT nCapRangeNominalValue; 
   L_INT nCapRangeStep; 
} LWIACAPRANGEVALUES,   * pLWIACAPRANGEVALUES; 

The LWIACAPRANGEVALUES structure provides information about the enumerated WIA capabilities of type WIA_PROP_RANGE.

Members

uStructSize

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

nCapRangeMinValue

Contains the minimum value for the received property.

nCapRangeMaxValue

Contains the maximum value for the received property.

nCapRangeNominalValue

Contains the normal or default value for the received property.

nCapRangeStep

Contains the Increment or decrement between the received property values.

Comments

This feature is available in LEADTOOLS version 16 or higher.

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

The structure is used by the LWia::EnumCapabilities function.
