Normalized Canvas-to-PDF Coordinate Inversion & Vector Content Overlay
PDF Coordinates: X_pt = nx × PageWidth, and Y_pt = PageHeight × (1 − ny) − BoxHeight. First, PDF.js renders the active page beneath a pointer-capture HTML5 overlay canvas. Next, your text stamps, whiteout blocks, 38%-opacity highlights, and ink strokes record normalized (nx, ny) positions. Finally, PDFLib writes crisp vector operators directly onto each ISO 32000 page stream.
Because our Edit PDF applies these rules automatically, you avoid manual rounding mistakes. Furthermore, users looking for free pdf editor or modify pdf workflows can test multiple scenarios side by side before finalizing their work.
