Now I want to remove the text which is below of the barcode. how can I do this?.


Solution:1

A better alternative might be to just use a font that doesn't have the text in the first place:

Try something like: Free Barcode Font - Code 39


Solution:2

You can set Font = null; to remove text below barcode.

Barcode128 code128 = new Barcode128();  code128.CodeType = Barcode.CODE128;  code128.Code = "123456789";  code128.Font = null;  


Solution:3

You are creating the barcode using a font and the charcters under the bars are part of that font.

The only way to remove them would be to modify the bitmap (or crop it) after rendering the text; which requires knowing how big the final barcode is. Not impossible to do but a pain.
