Set Barcode Size

This documentation provides a guide on how to set barcode sizes using in the Aspose.BarCode Cloud SDK for Python. This guide includes examples and descriptions for configuring the height, width, and resolution of barcode images.

Overview

The GenerateApi interface offers several methods for generating barcodes through different types of HTTP requests:

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

Key Parameters for Setting Barcode Size

To control the size of a barcode, the following properties in the request objects can be configured:

image_height: Specifies the height of the barcode image.
image_width: Specifies the width of the barcode image.
resolution: Defines the resolution (DPI) of the barcode image.
units: Defines the measurement units (e.g., pixel, inch, millimeter).

Example Usage

Example 1: Generating a Barcode with GET Request

import os
from aspose_barcode_cloud import (
    ApiClient,
    EncodeBarcodeType,
    GenerateParams,
    BarcodeImageParams,
    BarcodeImageFormat,
    EncodeData,
    EncodeDataType,
    Configuration,
)
from aspose_barcode_cloud.api.generate_api import GenerateApi


def make_configuration():
    env_token = os.getenv("TEST_CONFIGURATION_ACCESS_TOKEN")
    if env_token:
        config = Configuration(access_token=env_token)
    else:
        config = Configuration(
            client_id="Client Id from https://dashboard.aspose.cloud/applications",
            client_secret="Client Secret from https://dashboard.aspose.cloud/applications",
        )
    return config


def main():
    file_name = os.path.abspath(os.path.join(os.path.dirname(__file__), "..", "testdata", "qr.png"))

    configuration = make_configuration()
    api_client = ApiClient(configuration=configuration)
    generate_api = GenerateApi(api_client=api_client)

    generator_params = GenerateParams(
        EncodeBarcodeType.QR,
        EncodeData(EncodeDataType.STRINGDATA, "Aspose.BarCode.Cloud"),
        BarcodeImageParams(
            BarcodeImageFormat.PNG,
            image_height=200,
            image_width=200,
            resolution=300,
        ),
    )

    response = generate_api.generate_body(generator_params)

    with open(file_name, "wb") as file:
        file.write(response.data)

    print(f"File '{file_name}' generated.")


# Run the main function
if __name__ == "__main__":
    main()

Example 2: Generating a Barcode with POST Request (JSON Body)

import os
from aspose_barcode_cloud import (
    ApiClient,
    EncodeBarcodeType,
    EncodeDataType,
    EncodeData,
    GenerateParams,
    BarcodeImageParams,
    BarcodeImageFormat,
    GraphicsUnit,
    Configuration,
)
from aspose_barcode_cloud.api.generate_api import GenerateApi


def make_configuration():
    env_token = os.getenv("TEST_CONFIGURATION_ACCESS_TOKEN")
    if env_token:
        config = Configuration(access_token=env_token)
    else:
        config = Configuration(
            client_id="Client Id from https://dashboard.aspose.cloud/applications",
            client_secret="Client Secret from https://dashboard.aspose.cloud/applications",
        )
    return config


def main():
    # Define the output file path
    file_name = os.path.abspath(os.path.join(os.path.dirname(__file__), "..", "testdata", "pdf417.png"))

    # Create API client and generate parameters
    configuration = make_configuration()
    api_client = ApiClient(configuration=configuration)
    generate_api = GenerateApi(api_client=api_client)

    generate_params = GenerateParams(
        EncodeBarcodeType.PDF417,
        EncodeData(data="Aspose.BarCode.Cloud"),
        BarcodeImageParams(
            image_format=BarcodeImageFormat.PNG, image_height=2, image_width=3, resolution=96, units=GraphicsUnit.INCH
        ),
    )

    # Generate barcode and save to file
    response = generate_api.generate_body(generate_params)
    with open(file_name, "wb") as file:
        file.write(response.data)

    print(f"File '{file_name}' generated.")


# Entry point for async execution
if __name__ == "__main__":
    main()

Example 3: Generating a Barcode with POST Request (Form URL Encoded)

import os
from aspose_barcode_cloud import ApiClient, EncodeBarcodeType, Configuration, GraphicsUnit
from aspose_barcode_cloud.api.generate_api import GenerateApi


def make_configuration():
    env_token = os.getenv("TEST_CONFIGURATION_ACCESS_TOKEN")
    if env_token:
        config = Configuration(access_token=env_token)
    else:
        config = Configuration(
            client_id="Client Id from https://dashboard.aspose.cloud/applications",
            client_secret="Client Secret from https://dashboard.aspose.cloud/applications",
        )
    return config


def main():
    config = make_configuration()
    api_client = ApiClient(configuration=config)
    api = GenerateApi(api_client=api_client)

    file_name = os.path.abspath(os.path.join(os.path.dirname(__file__), "..", "testdata", "aztec.png"))

    response = api.generate_multipart(
        barcode_type=EncodeBarcodeType.AZTEC,
        data="Aspose.BarCode.Cloud",
        image_height=200,
        image_width=200,
        resolution=150,
        units=GraphicsUnit.POINT,
    )
    with open(file_name, "wb") as file_stream:
        file_stream.write(response.data)

    print(f"File '{file_name}' generated.")


if __name__ == "__main__":
    main()
