Java Class «PDF417Size»

java.lang.Object
de.vwsoft.barcodelib4j.twod.PDF417Size
public class PDF417Size extends Object
Immutable representation of a PDF417 symbol size.

PDF417 symbols are defined by their column count (1-30) and row count (3-90). The special value 0 can be used for either dimension to indicate automatic sizing based on the data to be encoded.

Examples: 

   // Fixed size: 10 columns, 20 rows
   PDF417Size fixed = new PDF417Size(10, 20);

   // Auto columns, fixed 20 rows
   PDF417Size autoCols = new PDF417Size(0, 20);

   // Fully automatic sizing
   PDF417Size auto = new PDF417Size(0, 0);
