Description |
uStructSize |
Size of this structure in bytes, for versioning. Use the sizeof() macro 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. |
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, you can 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 your program requires a pointer.
LWIACAPRANGEVALUES is used with the LWia::EnumCapabilities function.
