在這篇文章中,我們將討論如何使用 Java 創建條碼以及如何使用相同的 Java API 辨識條碼的細節。我們已經熟悉條碼是一種編碼標籤或標籤,放置在所有商品上,使電腦能夠更快且更準確地跟蹤和結帳商品。同樣,它們也可以輕鬆地印刷並及時添加到商品上,因此您的整個庫存都可以立即標記和跟蹤。此外,條碼提供自動產品識別、極快的識別和以非常低的錯誤率實施數據。這種方法是非常具有成本效益的,可以幫助雇主降低開支並縮短培訓時間和勞動力。
條碼生成 API
Aspose.BarCode Cloud 是一個 REST API,讓我們的客戶可以在編程中實現條碼生成和操作的功能。
該 API 能解析流行的光柵圖像格式。如需更多詳情,請訪問 Supported File Formats。
生成帶有指定尺寸的條形碼
測試我們的 API 最快速且簡單的方法是使用 API 參考部分。 GetBarcodeGenerate 方法用於創建條形碼圖像,它提供了多種選項以根據您的需求生成條形碼,並且與特定參數相關的詳細資訊在 API 參考頁面上有很好的解釋。在生成條形碼時,您可以指定以下類型中的任一種

辨識光柵圖像中的條碼
該 API 還提供從光柵圖像文件識別條形碼的能力。圖像文件可以是 PNG、JPEG、BMP、GIF、TIFF 或 EXIF 格式。API 的 GetBarcodeRecognize 方法使您能夠完成此要求。名稱字段是必需的,其他可選字段提供了更好的識別操作能力,因為您可以指定條形碼類型信息、ChecksumValidation、編碼、允許配置識別質量和速度的預設等等。

結論
在這篇文章中,我們討論了如何使用 Java 程式化地創建條碼的步驟和相關細節,以及如何使用 Java 程式碼片段讀取和識別現有的條碼。您可能已經注意到,所有這些操作都是用幾行簡單的程式碼完成的。無需額外的軟體下載或安裝,這些操作可以用更少的程式碼行來完成。
