Detailed research
Product Angle
PDF-XChange comparison users may have scanned PDFs with ugly dark borders. TextFaker can solve the image-level version first and later integrate with PDF page rendering if the project supports it.
- Lead with remove dark scan margins.
- Include black, white, and custom background modes.
- Show exact border pixels removed.
Demand Evidence
The PDF-XChange forum thread is especially relevant because the user explicitly asks whether dark margins from an ADF scanner can be removed automatically.
- ADF scanners create repeated edge artifacts.
- White-border crop is not enough for dark margins.
- Manual cropping is viewed as a last resort.
Implementation Notes
Offer a border color mode: auto, dark, light, and sampled corner. The sampled-corner option can make scanner-bed backgrounds deterministic without AI.
- Use corner sampling to estimate border color.
- Compute per-edge content transition thresholds.
- Expose threshold and minimum content area.
Testing
Fixtures should include black side bars, gray bottom bars, white margins, and mixed uneven borders. Each test should assert crop coordinates and status.
Research notes
- The PDF-XChange knowledge base explains crop pages and notes that cropping redefines visibility rather than necessarily removing content.
- A PDF-XChange forum user asks how to remove dark margins from ADF-scanned documents automatically and wonders if manual cropping is the only option.
- This is direct demand evidence for a specialized automatic scan-border cropper with dark-edge detection.
