ANSI C library for generating PDF documents entirely from scratch (no PDF import or editing) — a common embedded choice for C/C++ applications that need to produce reports or documents without shelling out to an external process. Draws lines, text, and images (PNG/JPEG, with CMYK, alpha-channel, and CCITT fax support), embeds Type1/TrueType/CJK fonts, and adds outlines plus text and link annotations. Supports document encryption, Deflate stream compression, and PDF/A-1b archival-compliant output.
