Reference Guide > QRGetActualRC Function

Gets the actual numbers of rows and columns for the QRCode barcode.

void QRGetActualRC(WORD *ActualRows, WORD *ActualCols);

Parameters

ActualRows

A pointer to the variable that receives the final number of rows for the QRCode barcode.

ActualCols

A pointer to the variable that receives the final number of columns for the QRCode barcode.

Remarks

If you set Version to 0 (Auto version), QRCode Win32 DLL will automatically choose an appropriate version with enough data capacity to encode the string, use this function to retrieve the information about the final numbers of rows and columns.

If you set Version to other values and the data capacity of the selected version is not big enough to encode the string, QRCode Win32 DLL will also automatically choose an appropriate version with bigger data capacity to encode the string, so the final numbers of rows and columns might not be equal to the numbers of rows and columns specified by the Version parameter.
