Barcodes
Adding a barcode
Section titled “Adding a barcode”Click the Barcode tool in the toolbar (or press B), then click the canvas. A barcode element is placed at a default size (minimum 100 × 40 px).
Barcode properties
Section titled “Barcode properties”Select the barcode element and find the Appearance section of the Properties panel.
Format
Section titled “Format”Choose the barcode symbology from the dropdown. Each option shows the format name and a brief description.
Common formats:
| Format | Best for |
|---|---|
| Code 128 | General-purpose; alphanumeric |
| Code 39 | Industrial / automotive |
| EAN-13 | Retail products (13 digits) |
| UPC-A | North American retail (12 digits) |
| ITF-14 | Shipping / carton labels (14 digits) |
For 2D QR codes, use the separate QR Code element — it isn’t one of the barcode formats.
Enter the value to encode. The placeholder shows the format expected for the selected symbology (e.g. exactly 13 digits for EAN-13). A validation icon shows whether the current value is valid.
This field can be bound to a variable for dynamic barcodes, from the Variable section at the top of the panel. See Variable Settings.
Bar Width
Section titled “Bar Width”Controls the width of individual bars — 1–4 px. Narrower bars produce a more compact barcode; wider bars are easier to scan on low-resolution prints.
Show Text
Section titled “Show Text”Toggle whether the encoded value is printed below (or above) the barcode.
When ON, additional controls appear:
| Control | Options |
|---|---|
| Text Pos. | Top / Bottom |
| Text Align | Left / Center / Right |
| Font Size | 8–32 px |
Colors
Section titled “Colors”| Control | Description |
|---|---|
| Line Color | Bar color (default: black) |
| Background | Background behind the bars (default: white) |
Always keep sufficient contrast between line and background colors for scanner reliability.
Size constraints
Section titled “Size constraints”Minimum width: 100 px · Minimum height: 40 px. The width and height fields in the Position & Size section won’t let you set a value below these minimums. Barcodes resize from their corner handles only.
