BARCODEWRITEMICROQR

typedef struct _tagBARCODEWRITEMICROQR 
{ 
   L_UINT uStructSize; 
   L_UINT32 ulFlags; 
   L_INT nXModule; 
   L_INT SymbolSize; 
} BARCODEWRITEMICROQR, * pBARCODEWRITEMICROQR; 

The BARCODEWRITEMICROQR structure contains information for writing MicroQR symbols.

Member Description
uStructSize Size of this structure in bytes. Use the sizeof() macro to calculate this value.
ulFlags Reserved for future use.
nXModule Specifies the size of the "modules" that make up the MICROQR barcode, in 0.001 inches. The module size = (the value of nXModule) X (the number of Modules in each row). The module is a "cell" that is used to make the symbol's grid. The default value is 10 pixels
SymbolSize Specifies which symbol size to use when writing a Micro QR barcode.
  Value Meaning
BARCODE_MICRO_QR_CODE Micro QR Auto size
BARCODE_MICRO_QR_CODE_M1 Micro QR M1
BARCODE_MICRO_QR_CODE_M2_L Micro QR M2 with error correction level L

BARCODE_MICRO_QR_CODE_M4_Q Micro QR M4 with error correction level Q

Comments

pBARCODEWRITEMICROQR is a pointer to a BARCODEWRITEMICROQR structure. Where the function parameter type is pBARCODEWRITEMICROQR, you can declare a BARCODEWRITEMICROQR variable, update the structure's fields, and pass the variable's address in the parameter. Declaring a pBARCODEWRITEMICROQR variable is necessary only if your program requires a pointer.

The Micro QR barcode is a smaller version of the QR code, used when working with severe space constraints.

The MICROQR standard specifies 4 different sizes of the MICROQR code. The maximum data capacity will vary, depending on the size and Error Correction level.
