zig-VectorNotes

Reimplementation of my C based VectorNotes application.

A super simple note taking application using vector based drawing.

Todo

Some lists for me to pick from when I want to work on this project.

Essentials

• Port my C program to Zig
• Undo/Redo system
• Better tools implementation
• Selection tool
• Optimize selection (prevent checks if user is zoomed in far)
• Deletion tool
• Map 0 to 1 parameters to a whole bezier Path and evaluate the path
• Only render paths in view
• Don't render paths zoomed out too far
• Save/load system
• Extract NanoVG wrapper into a separate library
• Proper memory error handling... (Get rid of catch unreachable)
• Squash memory leaks
• Minimal UI
• Better bounds calc for bezier paths
• Update Path interface
  • Refactor Path and Canvas systems
  • Eval for different path types (System is in place, specific eval functions not yet)
  • New draw system for paths

Bugs

• Path.eval does not work correctly when zoomed in far. (add scaling to counter float errors?)
• Fitting algo
  • Fix bug that results in a bunch of segments very close to one another
  • Fix bug where a point is sometimes placed somewhat randomly, sometimes very far away
  • The fit shifts what seems like a contant amount when zoomed in far
• Selection failure; Sometimes a selection that should work, does not select the path.

Future

• PDF viewer
• Export to different file formats
• Custom vector drawing library, with support for variable stroke widths
