Hi all this is the very first time I'm posting this question. I'm using iText
for generating barcodes and I'm experiencing following problems
1. Fixed barcode size:
I'm trying to fix barcode size but the size is not getting fixed
for barcodes.
2. Spacing for the Barcodes:
I have a barcode stickers which have 4 columns and 12 rows
i.e. one sheet holds 48 barcode stickers. I want to know about how to fix
the barcode size. Whwn I'm trying to print the barcode the first row prints
properly but the when the last row is to be printed it prints that last row
in the third last row of the sticker sheet.
Please help me finding the solution.
here is my code:
try {
Document document = new Document(PageSize.A4, 1f, 1f, 16f, 1f);
// step 2
PdfWriter writer = PdfWriter.getInstance(document, new
FileOutputStream("D://barcodr1.pdf"));
// step 3
document.open();
Barcode128 code128 = new Barcode128();
// step 4
PdfContentByte cb = writer.getDirectContent();
Class.forName("com.mysql.jdbc.Driver");
Connection cn =
DriverManager.getConnection("jdbc:mysql://localhost:3306/fireworks", "root",
"pranit");
PreparedStatement ps = cn.prepareStatement("select * from stock
where status = 'Not Printed'");
ResultSet rs = ps.executeQuery();
rs.beforeFirst();
String f = "";
PdfPTable table = new PdfPTable(4);
table.setWidthPercentage(100);
table.setSpacingAfter(1f);
int g = 0;
Image img = null;
while (rs.next()) {
g = rs.getInt("id");
f = rs.getString("bcode");
String a[] = f.split("_");
code128.setBarHeight(50f);
code128.setCode(rs.getString("bcode") + " " +
rs.getString("bname") + "" + rs.getString("itemname") + "" + a[1]);
code128.setCodeType(Barcode.CODE128);
img = code128.createImageWithBarcode(cb, null, null);
img.setWidthPercentage(80);
// img.scalePercent(50, 50);
//System.err.println(img.getHeight());
PdfPCell c1 = new PdfPCell(img);
c1.setBorder(0);
c1.setPadding(15);
c1.setColspan(0);
// c1.setRowspan(0);
c1.setHorizontalAlignment(Element.ALIGN_CENTER);
c1.setVerticalAlignment(Element.ALIGN_CENTER);
table.addCell(c1);
}
document.add(table);
document.close();
} catch (Exception e) {
JOptionPane.showMessageDialog(null, e, null,
JOptionPane.ERROR_MESSAGE);
}
