RPF to PDF Converter

About This Tool

Purpose & User Intent: This tool solves the need to convert RPF files to PDF for review, distribution, and archival. Target users include document managers, engineers, researchers, and design teams who receive RPF assets and require a stable, cross‑platform output. Use when you must preserve layout, embedded content, and font rendering, and when downstream systems require a widely supported, print‑ready format. Core Logic & Features: The converter ingests a single RPF file or an optional batch for queued processing. It performs format detection, validates version compatibility, and selects a rendering path based on content type. Required features: input_file and produced_pdf. Optional/advanced features: batch_mode, output_dpi (72–600), page_size (A4, Letter, etc.), color_mode (color, grayscale, monochrome), embed_fonts (true/false), pdf_version (1.4–2.0), and pdf_a_conformance (true/false). The tool preserves vector content when possible and rasterizes complex textures at the chosen DPI; fonts are embedded by default with subset optimization. Outputs include the produced PDF, page count, and file size; optional metadata and a simple integrity digest are added for traceability. The unique value proposition lies in automatic font embedding heuristics, conformance options, and per-page rendering decisions that balance fidelity and performance. Algorithms & Calculations: The process follows: detect RPF version and content; determine rendering strategy; render pages at the specified DPI; embed fonts as configured; compress streams; assemble into a standard PDF file; compute basic metadata and size estimates; return outputs. No external data feeds beyond the input file. Error & Edge Cases: If input is missing or unreadable, report a structural error. Unsupported RPF version, corrupted streams, or insufficient permissions yield precise error codes. DPI outside 72–600 or invalid page_size values trigger validation errors. Very large files may trigger memory bounds, with a managed fallback. Industry/Region & Localization: Adheres to PDF 1.7 baseline with optional PDF/A-2u conformance; uses metric units for page_size and standard points for page coordinates; supports locale-aware font naming when embedding. Localization focuses on language-agnostic rendering. Assumptions & Exclusions: Assumes the source RPF content is legally shareable and does not include non‑RPF transforms. The tool does not edit or interpret semantics beyond rendering; it does not convert non‑RPF assets and does not provide OCR or editing capabilities.
