Sobre os arquivos XBMComparativo de vantagens
PDF Vantagens
- Pixel-perfect fidelity across operating systems, browsers, and printers.
- Embeds fonts, so documents render identically without the reader having them installed.
- Supports digital signatures, encryption, and redaction for legal workflows.
- ISO-standardized (ISO 32000) with multiple validated subsets (PDF/A, PDF/X, PDF/UA).
- Supports both vector and raster content, keeping line art crisp at any zoom level.
XBM Vantagens
- Valid C source — embeddable.
- Text-editable.
- Tiny files.
- X11-native since 1989.
Limitações
PDF Limitações
- Editing is difficult — the format is optimized for display, not mutation.
- Text extraction can scramble reading order in multi-column layouts.
- File sizes balloon quickly when embedding high-resolution images or fonts.
- Accessibility (screen readers) requires careful tagging that many PDFs skip.
- JavaScript support has historically been a malware vector.
XBM Limitações
- 1-bit monochrome only.
- Legacy — modern UIs use PNG/SVG.
- No compression.
