Rpv Visual Editor can insert barcodes and QR codes in your reports. It is possible to do it by selecting the tool available in the vertical toolbar.
The barcodes, like the rest of the objects, will be contained within a section or a subsection.
When a barcode is inserted in the report, the object will look like the following:
The size of the barcodes, same as the labels cannot be modified using the mouse.
However, they can be altered using the properties height and BarWidh, the expression property and the sample value.
Unless the barcode expresses a fixed value, the field expression will always be (or contain) a variable that is retrieved from the Rpx or Rpv file.

the barwidth, expression and sample value properties will affect the height
of the object. |

It is remmarkable that each barcode has its
limitations regarding the characters that they can show. For example, STANDARD
3-9 has the ability to show letters and numbers. EAN13 can only show 13 numeric
positions while EAN8 can only show 8 chars. It is recommended to place real
values to avoid problems showing barcodes.
