TBarCode SDK by TEC-IT Barcode Symbologies and Configuration |
Part 3: Barcode Symbology Support and Configuration |
3.1 Overview of Barcode Symbology Support |
TBarCode SDK supports more than 100 barcode symbologies, including linear, 2D, and postal types, making it one of the most versatile commercial barcode generation components. Each symbology is designed to meet specific business or regulatory needs, and TBarCode SDK ensures that all generated barcodes are compliant with international standards, such as ISO/IEC 15417 for Code 128, ISO/IEC 16022 for Data Matrix, and USPS regulations for postal barcodes. Developers can select a barcode type programmatically and configure multiple parameters, including size, resolution, error correction, human-readable text, color, and rotation. |
|
3.2 Linear Barcode Types |
Linear barcodes, also known as 1D barcodes, encode information in one dimension using lines of varying width and spacing. TBarCode SDK supports the most common linear barcodes, including: |
* Code 128: A high-density alphanumeric barcode widely used in logistics and inventory management. It supports all 128 ASCII characters and includes a mandatory check digit. TBarCode SDK allows developers to select Code Set A, B, or C depending on the character set and compression needs. |
* Code 39: Commonly used in manufacturing and automotive industries, this barcode supports uppercase letters, digits, and a few special characters. TBarCode SDK can automatically append start/stop characters and calculate optional modulo-43 checksums. |
* EAN-13 / EAN-8: Used extensively in retail for product identification. EAN-13 encodes 12 digits plus a check digit, while EAN-8 is a shorter version for small items. TBarCode SDK calculates check digits automatically and allows for human-readable text placement above or below the barcode. |
* UPC-A / UPC-E: Primarily used in North America for retail products. TBarCode SDK supports conversion from UPC-A to UPC-E, quiet zone adjustments, and integration into POS systems. |
* Industrial 2 of 5 and Interleaved 2 of 5: Numeric-only barcodes commonly used in warehousing and industrial applications. The SDK provides configuration for start/stop characters, module width, and checksum calculation. |
|
3.3 2D Barcode Types |
2D barcodes encode information in both horizontal and vertical dimensions, allowing higher data density and error correction. TBarCode SDK supports a comprehensive range of 2D barcodes, including: |
* QR Code: A highly popular 2D barcode that can encode alphanumeric, numeric, or binary data. The SDK allows selection of version, size, and error correction level (L, M, Q, H). QR Code generation also supports optional masking patterns to optimize readability and reduce printing errors. |
* Data Matrix: A compact barcode ideal for labeling small items such as electronic components and pharmaceuticals. TBarCode SDK supports ECC 200 error correction and automatic module size adjustment based on input data length. |
* PDF417: A stacked linear barcode used for transport, identification, and document encoding. TBarCode SDK allows specification of row/column numbers, error correction levels, and compaction modes (text, numeric, or byte). |
* Aztec Code: Used in transport tickets and secure applications due to its high error tolerance. The SDK provides configurable symbol sizes and layered error correction. |
* MaxiCode: Developed by UPS for logistics and parcel tracking. TBarCode SDK supports both structured and unstructured modes, ensuring compatibility with courier and shipping systems. |
|
3.4 Postal Barcode Types |
Postal barcodes are designed for automated mail sorting and tracking. TBarCode SDK includes comprehensive support for global postal systems, such as: |
* Intelligent Mail Barcode (IMB): Used by USPS to encode routing, tracking, and service information. TBarCode SDK ensures compliance with USPS specifications and provides options for text placement, color, and quiet zones. |
* POSTNET and PLANET Code: Legacy USPS barcodes used for routing and automation. The SDK provides automatic check digit calculation and correct spacing for scanner readability. |
* KIX Code: Used by PostNL (Netherlands) for automated mail sorting. TBarCode SDK supports numeric input, checksum calculation, and barcode rendering for integration with domestic postal systems. |
* Royal Mail RM4SCC: The SDK allows encoding of UK-specific mail routing barcodes with proper spacing, bar height, and error checking. |
|
3.5 Configuration Options for Barcodes |
TBarCode SDK offers extensive configuration options to customize barcodes according to specific business needs: |
* Module Size / Bar Width: Developers can adjust the width of bars or modules to fit label sizes or printing resolution. |
* Quiet Zones: The SDK ensures compliance with standards by allowing customization of quiet zones (margins around the barcode). |
* Human-Readable Text: Placement, font, size, and content of human-readable text can be fully customized, including automatic generation of check digits. |
* Colors and Transparency: Barcodes can be rendered in custom foreground and background colors, including transparent backgrounds for overlay on images or labels. |
* Rotation and Orientation: Barcodes can be rotated in increments (090180270to fit label orientation requirements. |
* Error Correction: For 2D barcodes, developers can select the desired level of error correction to optimize readability under damaged or low-quality printing conditions. |
* Symbology-Specific Options: Certain barcodes, like QR Code or PDF417, have additional options such as mask patterns, compaction mode, or row/column configuration, all fully exposed through the SDK interface. |

3.6 Dynamic Barcode Generation |
TBarCode SDK supports dynamic barcode generation, allowing applications to produce barcodes based on real-time data. This includes reading input from databases, user input forms, web services, or sensor systems. Developers can embed barcode generation into workflows such as printing shipping labels, generating event tickets, producing ID cards, or dynamically creating product tags in manufacturing lines. The SDK ensures that each barcode complies with standard specifications and can be rendered in the required format without manual intervention. |
3.7 Integration with Printing Systems |
Barcodes generated by TBarCode SDK are designed for direct printing on industrial, desktop, and office printers. The SDK can output high-resolution images suitable for thermal transfer printers, inkjet, or laser printers. Developers can configure DPI (dots per inch), scaling, and color depth to match printer capabilities. Furthermore, TBarCode SDK supports embedding barcodes into print-ready documents or labels generated through Office applications, PDF documents, or custom printing engines. |
|
3.8 Symbol Validation and Testing |
TBarCode SDK includes built-in validation functions to ensure that generated barcodes are compliant with applicable standards. For linear barcodes, this includes verifying check digits and character set conformity. For 2D and postal barcodes, the SDK verifies module patterns, error correction codes, and spacing requirements. Developers can use these validation routines to prevent the creation of unreadable or non-compliant barcodes, which is critical in regulated industries such as pharmaceuticals, logistics, and postal services. |
3.9 Summary of Part 3 |
Part 3 has provided an in-depth analysis of TBarCode SDK support for barcode symbologies, including linear, 2D, and postal barcodes. We have examined configuration options, dynamic generation, integration with printing systems, and validation features. Understanding these capabilities allows developers to select the appropriate barcode type and settings for specific applications, ensuring compliance, readability, and professional output quality. |
