22. Technical Explanation: High-DPI Bitmap Stream Injection
Signatures are captured from an HTML5 Canvas drawing buffer at 300 DPI and embedded into the PDF structure:
- •Smooth Vector Curves: Uses Bezier spline smoothing to ensure drawn signatures look natural without jagged pixelation.
- •Transparent PNG Alpha Channel: Retains complete background transparency so text beneath the signature line remains legible.
- •Zero Cloud Exposure: Unlike commercial e-sign tools that log contracts in remote databases, our studio operates 100% locally in browser memory.
33. Legal Enforceability of Electronic Signatures
Standard electronic signatures (SES) created with verified intent are legally binding under the US ESIGN Act, EU eIDAS regulations, and Indian Information Technology Act for most commercial agreements.
