Sobre os arquivos XBMComparativo de vantagens
TIFF Vantagens
- Lossless by default — no generation loss on successive edits and saves.
- Supports any bit depth (1 to 32 bits per channel), any color model, any number of channels.
- Extensible tag system means vendor-specific data survives alongside standard tags.
- Multi-page containers are perfect for scanned documents, faxes, and DICOM-like stacks.
- Industry-standard for archival, museums, scientific imaging, and high-end print prepress.
XBM Vantagens
- Valid C source — embeddable.
- Text-editable.
- Tiny files.
- X11-native since 1989.
Limitações
TIFF Limitações
- File sizes are huge compared to JPEG/WebP/AVIF — often 10-30× larger.
- Not a web format — no browser displays TIFF natively.
- Ambiguous spec areas mean some TIFFs only open correctly in the tool that created them.
- Weak animation support — designed for still imagery.
XBM Limitações
- 1-bit monochrome only.
- Legacy — modern UIs use PNG/SVG.
- No compression.
