SVG Font Dependencies and Outline Guide
Inspect SVG text/tspan nodes, font-family declarations and font resource references; identify font-dependent text and learn how to create outlines.
About this svg font dependencies and outline guide
Inspect SVG text/tspan nodes, font-family declarations and font resource references; identify font-dependent text and learn how to create outlines Processes media assets directly in the browser using HTML5 Canvas and WebAssembly decoders, ensuring zero file uploads.
Image processing & canvas pipeline
Parses, optimizes, and transforms Scalable Vector Graphics (SVG 1.1 / SVG 2) XML DOM structures. The vector optimization pipeline cleans redundant metadata, editor namespaces (Inkscape, Adobe Illustrator), empty group tags (<g>), and comments. Numerical coordinates in path data ('d' attributes) are rounded to designated decimal precision, converting absolute commands (M, L, C, S) to relative commands (m, l, c, s) to minimize byte size. Rasterizes vector paths to high-resolution PNGs via OffscreenCanvas.
Worked image transformation example
Scenario: Report two heuristic SVG font safety findings.
Sample input:
Processing: Search for three text patterns; the sample contains <svg, <font-face and <script, so the two warning lines are returned without validating an XML root.
Illustrative output:
Resolution, dimension & memory limits
Operational constraints and validation boundaries: Both panels require UTF-8 input smaller than 10,000,000 bytes. The new inspector rejects empty/malformed XML, non-SVG roots and DTD/entity declarations. Reports include all matching nodes; each text preview is limited to 160 Unicode characters. CSS declaration scanning is conservative: no cascade, selector matching, shorthand, CSS escapes or remote font resolution. Installed-font availability, glyph coverage, license and visual appearance are unverified. No SVG is rendered, no reference fetched and no conversion/sanitization performed.
SVG Font Dependencies and Outline Guide image operations execute in client memory via HTML5 Canvas and browser decoders. Inspect output previews before replacing source assets.
In-memory image processing boundary
File buffers and document assets in SVG Font Dependencies and Outline Guide are processed in-memory via local browser APIs with zero file uploads to CZOA servers.
Image format & W3C Canvas standards

Frequently asked questions
What does the SVG font inspection reveal?+
Operational requirements for "What does the SVG font inspection reveal?" are verified in local memory during execution of SVG Font Dependencies and Outline Guide.
Which inputs and controls are exposed?+
Paste SVG and run the local DOMParser inspection. Each text/tspan node is listed by structural path, text preview and the nearest font-family attribute or inline declaration. Font-family declarations in style blocks and common URL/import/font URI references are listed separately without loading them. Example: a text element with font-family="Brand Sans" containing one tspan produces two live-node warnings; the child inherits the parent’s declared font candidate. Original three text checks remain below.
What limits apply to the linter?+
Both panels require UTF-8 input smaller than 10,000,000 bytes.
What result should the documented example produce?+
Original three text-pattern checks: For an SVG containing font-face and script, it returns both legacy-font and disallowed-script messages.
