Barcode

Bug Fixes

  • #I877780 - Fixed QR code scanning failures caused by incorrect error correction codeword generation.

Features

  • Added the PDF417Generator component for rendering PDF417 barcodes (ISO/IEC 15438), including Compact PDF417.
    • Automatic Text, Numeric and Byte compaction, or a fixed mode through compactionMode. Non-ASCII values are encoded as UTF-8 with an ECI designator.
    • Error correction levels 0-8 through errorCorrectionLevel, defaulting to the level recommended for the data length.
    • Row height relative to the module width through rowHeightRatio (minimum 3, as required by ISO/IEC 15438).
    • Rows (3-90) and columns (1-30) are calculated automatically to give the largest module size that fits the component, or can be set through rows and columns.
    • SVG and Canvas rendering, foreColor, backgroundColor, margin, displayText, image export, localization and role/aria-label attributes.
    • The invalid event reports invalid values, rows, columns, error correction levels, sizes and values that exceed the symbol capacity.

GanttChart

Bug Fixes

  • Enhanced Gantt Chart performance and scalability through internal optimizations, delivering up to 2.5 times faster loading and execution speeds for large project datasets. Validated with projects containing up to 50,000 tasks and task hierarchies up to 10 levels deep, providing a more responsive user experience for complex scheduling scenarios.

Ribbon

Bug Fixes

#I875122 - Now, Ribbon tab item color contrast works properly and meets accessibility requirements.
