For help on a barcode symbology see the topic Symbologies.

A barcode settings dialog box is made up of 5 tabs:

Symbol: this tab enables you to select the type of barcode you want to display.

The right pane Quick Info displays some useful information about the compilation of the text to be encoded. Click the More link to display the help page about the barcode type currently selected.

At the bottom, the text box that allows the compilation of the text to be encoded and buttons for inserting elements for a possible linkage with data source fields, counters, and to preview the resulting text to be encoded. See topic Text concatenation for more information.

Note:
When you connect a barcode element to a database field, all rules described earlier will still apply for a correct rendering of the barcode. When an entry is found that does not comply with the above rules, the barcode will not be displayed.

As far as fixed-length numeric barcodes EAN-13, EAN-8, ITF-14, UPC-A e UPC-E go, in case the number of digits found in the data source is larger than the allowed capacity, only the applicable number of digits will be considered. In case the number of digits is smaller than required, the barcode will not be generated.

For example, if you connect an EAN-13 barcode to a data source containing 13 digits, only the first 12 will be read by Labeljoy, and the 13th digit (checksum) will be generated internally. On the other hand, if a record with less the 12 digits is found, no barcode image is generated for that particular position.

Based on the type of barcode selected, Labeljoy will require you to enter a few additional parameters needed to correctly generate the barcode symbol.
See the topic Symbologies.

Font: tab for the selection of the font to be used to draw the optional text below or above linear barcode symbols.
In this case, it is not possible to define normal font effects such as Bold or Italic.
Labeljoy enables you to define font size in percentage steps based on the standard font size (100%) as defined in each symbology technical specifications.
The font list is alphabetically sorted.

Pen: tab for the definition of color used for the rendering of the bars and any text that may appear at the top or at the bottom.

Note:
To ensure that barcode symbols are easily read by scanners, it is necessary to maintain a strong contrast between the background color and that of the symbol. In fact, in most cases white is used for the background and black for the symbol.

See the Defining colors topic for more information on creating complex colors and shades.

Background: tab for the definition of the background color of the barcode.

See the Defining colors topic for more information on creating complex colors and shades.
