- Crop out excess white space around the signature before adjusting dimensions.
- Check the specific portal guidelines for minimum and maximum KB boundaries.
Troubleshooting & Common Issues
- Signature lines appear broken: Lower the Background Whitening threshold slider so fine pen strokes are preserved.
- Background remains grey: Increase the contrast and whitening sliders until the background turns solid white.
