QRCodeGenLib4Pascal

About

QRCodeGenLib4Pascal is a Delphi/FPC compatible library that provides an easy to use interface for generating QR Codes, from text strings and byte arrays.

Core features:

• Supports encoding all 40 versions (sizes) and all 4 error correction levels, as per the QR Code Model 2 standard.
• Output formats: Raw modules/pixels of the QR symbol, SVG XML string/file, Image object (bmp, jpg, png).
• Encodes numeric and special-alphanumeric text in less space than general text.
• Ability to change the backgound and foreground colors of the generated QRCode.

Manual parameters:

• User can specify minimum and maximum version numbers allowed, then library will automatically choose smallest version in the range that fits the data.
• User can specify mask pattern manually, otherwise library will automatically evaluate all 8 masks and select the optimal one.
• User can specify absolute error correction level, or allow the library to boost it if it doesn't increase the version number.
• User can create a list of data segments manually and add ECI segments.
