Streaming PDF-417 Image into Your ASP.NET Web Pages Using ASP.NET Barcode Generator
Top- Under downloaded trial package, copy barcode folder and its contents to your IIS, and create a new virtual directory, named "barcode".
- Restart IIS, navigate to http://YourDomain:Port/barcode/pdf417.aspx?DATA=012345678.
- To create barcode image in html or aspx pages, you can insert a image tag (img) into your web pages.
For example, <img src="http://YourDomain:Port/barcode/pdf417.aspx?DATA=012345678" />
Generate PDF-417 into Your ASP.NET Web Forms
Top- Install ASP.NET Barcode Generator Control.
- Add ASP.NET Barcode Generator Control to your Visual Studio ToolBox.
- Copy "pdf417.aspx" and "pdf417.aspx.cs" to the folder where your aspx pages are generating barcodes.
- Drag and drop "PDF417WebForm" to your ASPX web forms.
- Run the website to view the barcodes generated. To customize PDF-417 settings, view PDF-417 barcode settings.

PDF417 Barcode Data Encoding in ASP.NET
PDF417 Valid Character Set
PDF417 supports extensive character encoding for ASP.NET application requirements:
- Full ASCII set (128 standard characters)
- Extended ASCII (values 128–255, ISO 8859-1 compliant)
- Support for over 811,800 character sets and data interpretations
- Dedicated function codewords for control operations
PDF417 Data Compaction Modes
PDF417 uses three optimized compaction modes to maximize data efficiency.
Set these via the DataMode property in your ASP.NET code.
Set these via the DataMode property in your ASP.NET code.
- Text Compaction mode: Encodes all printable ASCII (32–126) and selected control characters
- Byte Compaction mode: Encodes all 256 8-bit byte values, supporting international character sets
PDF417 Maximum Data Length
Maximum character capacity at Error Correction Level 0:
- Text Compaction mode: 1,850 characters
- Byte Compaction mode: 1,108 characters
- Numeric Compaction mode: 2,710 characters
Encode Multiple Text Types in PDF417 in ASP.NET
This section covers encoding various text formats in ASP.NET PDF417 generation.
Generate PDF417 with ASCII Text (Printable & Non-Printable)
Printable ASCII Characters
Directly assign standard text to the Data property
Non-Printable ASCII Characters
For control characters (e.g., Carriage Return), use the ~ddd format:
Note: Always use 3-digit padding for ASCII values (e.g., ~013 not ~13). Incorrect formatting will cause encoding failure.
Directly assign standard text to the Data property
Non-Printable ASCII Characters
For control characters (e.g., Carriage Return), use the ~ddd format:
- Convert non-printable characters to 3-digit ASCII values (e.g., CR = 13 > ~013)
- Enable ProcessTilde = true to activate special character parsing
Note: Always use 3-digit padding for ASCII values (e.g., ~013 not ~13). Incorrect formatting will cause encoding failure.
Generate PDF417 with Unicode Text Encoding
Encode international text (Unicode) in your ASP.NET project with one simple property:
- Create a PDF417 object
- Set EncodeUnicodeText = true
- Assign Unicode text to the Data property
PDF417 Dimension & Size Settings in ASP.NET
Customize barcode size, module dimensions, and margins for your ASP.NET UI or printing needs.
Adjust these core properties for PDF417 dimension control:
Adjust these core properties for PDF417 dimension control:
- UOM: Unit of measure (PIXEL, CM, INCH)
- X: Width of a single barcode module (minimum defined by your spec)
- XtoYRatio: Width-to-height ratio (default: 0.3333333)
- RowCount: Number of rows (range: 3 - 90)
- ColumnCount: Number of columns (range: 1 - 30)
- LeftMargin/RightMargin/TopMargin/BottomMargin: Quiet zone (minimum: 2X)
- Resolution: Image DPI (for high-resolution printing)
Advanced PDF417 Options for ASP.NET Projects
PDF417 Error Correction Level (ECL)
PDF417 uses robust error correction for data recovery.
Set the ECL property in ASP.NET to adjust fault tolerance:
- Level 0: 2 error correction codewords
- Level 1: 4 codewords
- Level 2: 8 codewords
- Level 3: 16 codewords
- Level 4: 32 codewords
- Level 5: 64 codewords
- Level 6: 128 codewords
- Level 7: 256 codewords
- Level 8: 512 codewords
Create Compact (Truncated) PDF417 in ASP.NET
Truncated PDF417 reduces size for space-constrained ASP.NET interfaces:
- Set Truncated = true to enable compact mode
- Ideal for low-risk environments where physical damage is unlikely
Create Macro PDF417 Barcodes
Macro PDF417 splits large datasets across multiple barcodes for ASP.NET applications:
Use this mode when your data exceeds the standard PDF417 character limits.
- Supports up to 99,999 linked PDF417 symbols
- Embeds reconstruction metadata for automatic data assembly
- Functions like Structured Append for high-capacity data storage
- Maintains data integrity regardless of scan order
Use this mode when your data exceeds the standard PDF417 character limits.
