Technical Architecture & Execution Mechanics
Local Image-to-PDF Stream Encoding
During compilation, each selected image is decoded into an HTML5 Canvas bitmap buffer to evaluate native pixel dimensions and aspect ratios. The tool instantiates a client-side PDF document structure with an indirect XObject image dictionary. Image bytes are embedded as raw DCTDecode or FlateDecode streams directly matched to standard ISO 32000-1 PDF page coordinate systems (e.g. 595.28 x 841.89 points for standard A4 at 72 points-per-inch).
Page Points: Width = (mm / 25.4) * 72 | Height = (mm / 25.4) * 72Technical Limitations & Operational Constraints
- Maximum recommended batch is 50 high-resolution images per compile to ensure smooth browser RAM handling.
- Corrupt or unsupported RAW camera formats (.CR2, .NEF) must be exported to standard JPG/PNG before conversion.
