fastqr's Issues

Style Picker

Need a style picker on the front end and corresponding rust method/s.

Let users mix and match between:

• Squares
• Circles
• Rounded Corner Squares
• Blobs
• Separate or Connecting
  • Horizontal or Vertical or Both Connecting

PNG/JPG Export

Need a conversion from SVG -> PNG or JPG function.

Possible implementations:

Generation

• Generate all versions per click and have at the ready
• Convert only when called upon

Display

• Force direct a tag download using base64 encoding
• Display on the page as png/jpg and direct user to right click download

Reduce wasm binary size

Most likely have to trim the source code for the library. The encoding and svg_to_string method is probably all we need. JS canvas can do an svg -> png conversion with little effort.

Position squares identifier

Need to implement an algorithm that identifies the positional squares in the upper left, upper right, and bottom left corners. They are a 7x7 perimeter with a 3x3 filled in square internally

Color Picker

Need a color picker on the front end
