Customize Barcode Appearance

This documentation explains how to customize the appearance of barcodes using the Aspose.BarCode Cloud SDK for Java. It provides details on the available methods, customization options, and examples of usage.

Methods

generate: Generates a barcode via GET request.
generateBody: Generates a barcode via POST request with JSON or XML body.
generateMultipart: Generates a barcode via POST request with multipart form data.

Customization Options

When generating a barcode, you can customize various aspects of its appearance using the properties of the request classes.

Key Properties:

barcodeType: Specifies the type of barcode to generate (e.g. QR, Aztec, Pdf417, Code39, etc).
data: The data to encode in the barcode.
imageFormat: Specifies the output format of the barcode image (e.g., Png, Jpeg, Svg).
foregroundColor: Color of the barcode bars, supports standard color names or ARGB values (e.g., AliceBlue or #FF000000).
backgroundColor: Background color of the barcode image.
textLocation: Position of the code text relative to the barcode (Below, Above, None).
units: Measurement units for image dimensions (Pixel, Inch, Millimeter).
resolution: Resolution of the image in dpi.
imageHeight and imageWidth: Dimensions of the barcode image.
rotationAngle: Rotation angle of the barcode (e.g., 0, 90, 180).

Examples

Example 1: Generating a Barcode with GET Request

import com.aspose.barcode.cloud.ApiClient;
import com.aspose.barcode.cloud.api.GenerateApi;
import com.aspose.barcode.cloud.model.BarcodeImageFormat;
import com.aspose.barcode.cloud.model.CodeLocation;
import com.aspose.barcode.cloud.model.EncodeBarcodeType;
import com.aspose.barcode.cloud.requests.GenerateRequestWrapper;

import java.io.File;

public class GenerateGet {
    public static void main(String[] args) {
        String accessToken = System.getenv("TEST_CONFIGURATION_ACCESS_TOKEN");
        ApiClient client;

        if (accessToken != null && !accessToken.isEmpty()) {
            client = new ApiClient(accessToken);
        } else {
            client =
                    new ApiClient(
                            "Client Id from https://dashboard.aspose.cloud/applications",
                            "Client Secret from https://dashboard.aspose.cloud/applications");
        }

        GenerateApi generateApi = new GenerateApi(client);

        try {
            GenerateRequestWrapper request =
                    new GenerateRequestWrapper(EncodeBarcodeType.QR, "Aspose.BarCode.Cloud");

            request.imageFormat = BarcodeImageFormat.PNG;
            request.foregroundColor = "Black";
            request.backgroundColor = "White";
            request.textLocation = CodeLocation.BELOW;
            request.imageHeight = 200f;
            request.imageWidth = 200f;
            request.resolution = 300f;

            File barcodeImage = generateApi.generate(request);

            System.out.println("Barcode image saved to file " + barcodeImage.getAbsolutePath());

        } catch (Exception e) {
            System.err.println("Error");
            e.printStackTrace();
            System.exit(1);
        }
    }
}
