Vector Graphics Overview

Overview

HotPDF supports vector-oriented workflows in two main ways: direct page drawing through the THPDFPage API and metafile import through EMF/WMF helper methods.

Main Approaches

• Direct Drawing: Use THPDFPage methods for lines, curves, fills, text placement, and other PDF canvas operations
• Metafile Import: Use THPDFPage.ShowMetafile to place EMF or WMF content on the page
• Layout Control: Combine page drawing with scaling, positioning, and current-page state changes
