tc-lib-pdf-graph generates the content stream commands for the graphic and geometric primitives of a PDF document.

• Points, lines, rectangles and Bezier curves
• Ellipses, circles, elliptical arcs and pie sectors
• Polygons, regular polygons, star polygons and rounded rectangles
• Arrows, crop marks and registration marks

• Style stack with line width, cap, join, miter limit, dash pattern and colors
• Path-painting and clipping operators
• Transparency, blend modes and overprint through ExtGState objects
• PDF/A mode that suppresses the ExtGState and shading output

• Axial and radial shadings with multiple color stops and per-stop opacity
• Coons patch meshes and color registration bars

• Scaling, rotation, mirroring, reflection, translation and skewing
• Transformation matrix product and transformation stack

• PHP 8.2 or later
• Extension: zlib
• Composer
