Visual Parameters & Layout

Visual Parameters & Layout

Visual parameters control how barcode data is rendered. Common settings are available from generator.getParameters() and generator.getParameters().getBarcode().

Configure common layout parameters

BarcodeGenerator generator = new BarcodeGenerator(
        EncodeTypes.CODE_128,
        "LAYOUT-EXAMPLE"
);

generator.getParameters().getBarcode().getXDimension().setPixels(2.0f);
generator.getParameters().getBarcode().getBarHeight().setPixels(90);
generator.getParameters().getBarcode().getPadding().getLeft().setPixels(24);
generator.getParameters().getBarcode().getPadding().getRight().setPixels(24);
generator.getParameters().getBarcode().getCodeTextParameters()
        .setLocation(CodeLocation.BELOW);
generator.getParameters().getImageWidth().setPixels(520);
generator.getParameters().getImageHeight().setPixels(180);

The most important layout groups are:

• Unit values for pixels and physical measurements;
• X-dimension and bar height;
• image width and height;
• padding around the barcode;
• captions and human-readable text;
• colors, borders, backgrounds, and rotation;
• symbology-specific dimensions.

A large image canvas does not automatically make barcode modules larger. Module size is controlled by X-dimension unless an auto-size mode recalculates it.
