Set Barcode Source

To perform barcode recognition using the Aspose.BarCode.Cloud SDK for Swift, you need to set the source of the barcode image. Methods of this SDK support loading barcode images from multiple sources, such as file URL, Data, and base64 encoded data. This guide provides detailed examples on how to set barcode image source through different API methods.

Supported Barcode Image Formats

JPEG
TIFF
PNG
BMP
GIF

Supported Barcode Source Formats

File URL: Link directly to an image URL.
Data: The image file bytes for processing.
Base64 Encoded Image: Convert the image to a base64 encoded string for secure transfer.

Examples for ScanAPI

Using GET Request with File URL

import AsposeBarcodeCloud
import Foundation

let client = AsposeBarcodeCloudClient(
    clientId: "Client Id from https://dashboard.aspose.cloud/applications",
    clientSecret: "Client Secret from https://dashboard.aspose.cloud/applications"
)
let barcodeImageURL =
    ProcessInfo.processInfo.environment["TEST_CONFIGURATION_BARCODE_IMAGE_URL"]
        ?? "https://raw.githubusercontent.com/aspose-barcode-cloud/Aspose.BarCode-Cloud-SDK-for-Swift/main/testdata/QR_and_Code128.png"

let response = try await ScanAPI.scan(
    fileUrl: barcodeImageURL,
    apiConfiguration: client.apiConfiguration
)

print(response.barcodes?.first?.barcodeValue ?? "No barcode found")

Using POST Request with Base64 Encoded Image

import AsposeBarcodeCloud
import Foundation

let client = AsposeBarcodeCloudClient(
    clientId: "Client Id from https://dashboard.aspose.cloud/applications",
    clientSecret: "Client Secret from https://dashboard.aspose.cloud/applications"
)

let imageData = try Data(contentsOf: URL(fileURLWithPath: "qr.png"))
let request = ScanBase64Request(fileBase64: imageData.base64EncodedString())

let response = try await ScanAPI.scanBase64(
    scanBase64Request: request,
    apiConfiguration: client.apiConfiguration
)

print(response.barcodes?.first?.barcodeValue ?? "No barcode found")

Using POST Request with File Stream

import AsposeBarcodeCloud
import Foundation

let client = AsposeBarcodeCloudClient(
    clientId: "Client Id from https://dashboard.aspose.cloud/applications",
    clientSecret: "Client Secret from https://dashboard.aspose.cloud/applications"
)

let imageData = try Data(contentsOf: URL(fileURLWithPath: "qr.png"))
let response = try await ScanAPI.scanMultipart(
    file: imageData,
    apiConfiguration: client.apiConfiguration
)

print(response.barcodes?.first?.barcodeValue ?? "No barcode found")

Examples for RecognizeAPI

Using GET Request with File URL

import AsposeBarcodeCloud
import Foundation

let client = AsposeBarcodeCloudClient(
    clientId: "Client Id from https://dashboard.aspose.cloud/applications",
    clientSecret: "Client Secret from https://dashboard.aspose.cloud/applications"
)
let barcodeImageURL =
    ProcessInfo.processInfo.environment["TEST_CONFIGURATION_BARCODE_IMAGE_URL"]
        ?? "https://raw.githubusercontent.com/aspose-barcode-cloud/Aspose.BarCode-Cloud-SDK-for-Swift/main/testdata/QR_and_Code128.png"

let response = try await RecognizeAPI.recognize(
    barcodeType: .qr,
    fileUrl: barcodeImageURL,
    apiConfiguration: client.apiConfiguration
)

print(response.barcodes?.first?.barcodeValue ?? "No barcode found")

Using POST Request with Base64 Encoded Image

import AsposeBarcodeCloud
import Foundation

let client = AsposeBarcodeCloudClient(
    clientId: "Client Id from https://dashboard.aspose.cloud/applications",
    clientSecret: "Client Secret from https://dashboard.aspose.cloud/applications"
)

let imageData = try Data(contentsOf: URL(fileURLWithPath: "qr.png"))
let request = RecognizeBase64Request(
    barcodeTypes: [.qr],
    fileBase64: imageData.base64EncodedString()
)

let response = try await RecognizeAPI.recognizeBase64(
    recognizeBase64Request: request,
    apiConfiguration: client.apiConfiguration
)

print(response.barcodes?.first?.barcodeValue ?? "No barcode found")

Using POST Request with File Stream

import AsposeBarcodeCloud
import Foundation

let client = AsposeBarcodeCloudClient(
    clientId: "Client Id from https://dashboard.aspose.cloud/applications",
    clientSecret: "Client Secret from https://dashboard.aspose.cloud/applications"
)

let imageData = try Data(contentsOf: URL(fileURLWithPath: "qr.png"))
let response = try await RecognizeAPI.recognizeMultipart(
    barcodeType: .qr,
    file: imageData,
    apiConfiguration: client.apiConfiguration
)

print(response.barcodes?.first?.barcodeValue ?? "No barcode found")

Conclusion

Using the Aspose.BarCode.Cloud SDK for Swift, you can easily load and recognize barcode images in file URL, Data, and base64 encoded formats.

Optimize your barcode recognition workflows by selecting the most appropriate method based on your specific image format and application requirements.
