Go library built on top of gopdf for generating banded PDF reports in the style of classic report-writing tools: page headers/footers, grouped headers and summaries, detail bands for row-level data, and an overall report summary section. Draws text cells, lines, rectangles/ovals, JPEG images, and TrueType fonts across multiple page sizes and orientations. Aimed at business-report generation (invoices, statements, listings) rather than general-purpose PDF creation.
