Working for the V2.0.0

I have successfully released the first version of it. So I have been working on adding some more features for the next version.

MicroQR Support

This is one of the most requested feature here. It is little tricky to make it work. But most logic for this has been programmed.

SVG Optimization

Drastically reduced SVG file size by merging modules into a single element.

Security

Added HMAC-SHA256 signing and bitwise XOR obfuscation to protect sensitive QR data.

Safety

Automatically detects low contrast between foreground and background. Includes auto_fix_contrast to force scannable colors.
