The BarCode element is just one, and it is used to show barcodes of many types on the report.
This element is inherited from geraldo.graphics.Graphic
Path: geraldo.barcodes.BarCode
This is the once class you can use to show bar codes. It supports the following bar code types, supplied by ReportLab barcodes library:
Attributes
name - Default: None
visible - Default: True
Set to False if you want to make it not visible.
height - Default: 1.5*cm
width - Default: 0.03*cm
This attribute does not set the barcode width, but the bar width, what means it is the width of the minimum bar of a barcode. You should set values like 0.02*cm or something like that (i.e. never 5*cm).
attribute_name - Default: None
As same as geraldo.widgets.ObjectValue, this attribute reffers to an attribute, attribute path or method to get the barcode value.
checksum - Default: 0
Most of barcode types supports you set the number of digits for checksum.
routing_attribute - Default: None
Useful only for USPS_4State barcodes. Works like attribute_name, but routing attribute of barcode.
Rendering attributes
They are read-only attributes you can use at render time.
