Hello,
For a proof-of-concept, SDL (or X) is enough. The editor needs this
functionality:
- Draw shapes.
- Change curves of existing shapes.
- Change properties of existing shapes:
stroke width, stroke color, and fill color
- Load (paint[1] lets the user type 'rFILE' to load FILE)
- Save (paint[1] lets the user type 'wFILE' to save FILE)
- Nest/reference other files, like "symbols" in Adobe Flash.
SVG and Asymptote both look very complicated... PostScript is a good
output language but not a good source-file language. Maybe we need a
new source-file format. See the attached proposal.
How about a trio of programs like this?
vectorrender - render a file and forbid circular dependencies.
vectoredit - graphically edit a single file. fork()s to `vectorrender`
vector2ps - convert a file to PostScript.
