Set Barcode Colorscheme

This documentation provides a comprehensive guide on how to set the colorscheme for barcodes using the Aspose.BarCode Cloud SDK for Java. The API allows customization of barcode appearance, including foreground and background colors, ensuring your barcodes match your design needs.

Overview

The GenerateApi interface includes methods to generate barcodes using different request formats:

generate: GET request with parameters in route and query string.
generateBody: POST request with parameters in the body (JSON or XML).
generateMultipart: POST request with parameters in multipart form.

Colorscheme Parameters

The foregroundColor and backgroundColor properties enable you to define the colors for the barcode:

foregroundColor: Specifies the color of the bars and text.
backgroundColor: Specifies the background color of the barcode image.

Both properties accept standard color names or ARGB values (e.g., AliceBlue or #FF000000).

Examples

Example 1: Setting Colors Using 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.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, "https://products.aspose.cloud/barcode/family/");
            request.foregroundColor = "DarkBlue";
            request.backgroundColor = "LightGray";
            request.imageFormat = BarcodeImageFormat.PNG;

            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);
        }
    }
}

Example 2: Setting Colors Using POST Request with JSON Body

import com.aspose.barcode.cloud.model.EncodeData;
import com.aspose.barcode.cloud.model.EncodeDataType;
import com.aspose.barcode.cloud.model.GenerateParams;
import com.aspose.barcode.cloud.requests.GenerateBodyRequestWrapper;

import java.io.File;

public class GenerateBody {
    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 {
            EncodeData encodeData = new EncodeData("Aspose.BarCode.Cloud");
            encodeData.setDataType(EncodeDataType.STRING_DATA);

            BarcodeImageParams imageParams = new BarcodeImageParams();
            imageParams.setForegroundColor("#FF5733");
            imageParams.setBackgroundColor("#FFFFFF");
            imageParams.setImageFormat(BarcodeImageFormat.JPEG);

            GenerateParams generateParams =
                    new GenerateParams(EncodeBarcodeType.PDF417, encodeData);
            generateParams.setBarcodeImageParams(imageParams);

            GenerateBodyRequestWrapper request = new GenerateBodyRequestWrapper(generateParams);

            File barcodeImage = generateApi.generateBody(request);

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

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

            client = new ApiClient(accessToken);
        } else {

            request.foregroundColor = "Green";

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

        } catch (Exception e) {
