svg2fti

A very-much-so-held-together-by-tape helper for converting SVGs to SGI FTI vector format.

python3 -m pip install -r requirements.txt

usage: svg2fti.py [-h] --svg SVG [--out OUT] [--num_samples NUM_SAMPLES] [--color_map COLOR_MAP]
svg2fti.py: error: the following arguments are required: --svg

Example

python3 svg2fti.py --svg nedit.svg

Input SVG on left.

Output FTI on right as visualized by Aqua Phoenix FTI Editor

Notes

Geometry

• Polygon vs line: if a fill color value cannot be resolved, bgnline() is used
• Scale: FTI coords are 100x100,
• Curves: SVG paths mapped to lists of vertices, increasing num_samples will make smoother

Color attributes

Colors parsed with tinycss2.color3 from:

• stroke

• fill

• style

• Gradients are ignored

• Try to follow url(#id): the first (via xpath query) color attribute is chosen

Palette

• Valid values are 0 -> 15, -16 -> -255
  • 0 -> 15 are a basic color table
  • -16 -> -255 are other colors that are interpolated combinations of colors 0 -> 15
• color_map.json contains a mapping of FTI color palette index to RGB values
• Only palette colors available, color with smallest delta to input chosen

Credits

• svg.path and tinycss2 made it possible to sketch this up so fast!
• AquaPhoenix's FTI Editor & Specs helped make testing this not painful.
