Tritium UI
TritiumBarcodeView
Draw a scannable barcode or QR symbol from a string and export it as a PNG.
Key features
- Encode retail, postal, logistics, and payment symbols, including Code 128, Code 39, EAN/UPC, ITF, Codabar, Code 93, MSI, Plessey, PDF417, Data Matrix, Aztec, QR, and the GS1 DataBar family.
- Generate specialized symbols such as Micro QR, rMQR, MaxiCode, Intelligent Mail, POSTNET, PLANET, Royal Mail, KIX, Mailmark, Australia/Japan/Korea Post, PharmaCode, DotCode, Telepen, Code 11, Code One, Aztec Runes, HIBC, and VIN.
- Produce payment and European profiles including EPC QR, Swiss QR-bill, UPN QR, Code 32, PZN8, Identcode, Leitcode, DPD, and ITF-14.
- Turn on GS1-128 (FNC1) for Code 128, and infer GS1 formatting when the value already looks like an element string.
- Set the symbol and its value together so the preview does not blank out on an intermediate invalid pair.
- Choose foreground and background colors for the symbol.
- Export a PNG file at the size you request.
- Call UseTritiumBarcode() once at startup before you show a scanner or generator.
