Parameters

LBitmapBase * pLBitmap

Pointer to the bitmap object to be associated with the class object.

Before using some of the LBarCode functions, a bitmap must be associated with the class object.

Specifically, barcodes cannot be read or written until a valid bitmap is associated with the class object.
