What SVG Flattening Actually Does
picosvg resolves every transform, group nesting, and use element reference in an SVG down to a flat set of simple path elements with absolute coordinates, producing output that's far easier for downstream tools like font compilers or icon rendering libraries to parse without implementing full SVG transform and grouping logic.
- Resolves every transform and group nesting down to absolute path coordinates
- Removes use element references by inlining their referenced content directly
- Produces output far easier for font compilers and icon libraries to parse
Why Icon and Font Pipelines Need Flattened SVGs
Tools that build icon fonts or color font formats often only support a restricted SVG subset without transforms or nested groups, so flattening source SVGs with picosvg before feeding them into a font compiler avoids compilation errors and ensures every glyph renders with the exact intended geometry.
- Icon font and color font compilers often only support a restricted SVG subset
- Flattening avoids compilation errors from unsupported transforms or nesting
- Ensures every glyph renders with the exact intended geometry after compilation
Frequently Asked Questions
What does 'flattening' mean in the context of picosvg?
Flattening means resolving all transforms, groups, and use references into a single flat list of path elements with absolute coordinates and no remaining nesting.
Why would a font pipeline require flattened SVGs specifically?
Many font compilation tools only support a simplified SVG subset, so flattening upstream avoids errors from transforms or grouping constructs those tools can't parse.
