Doc Glyph (▤)

Inline document viewer on canvas. Drag a file onto the canvas to upload it and spawn a Doc glyph.

Supported formats

PDF, PNG, JPG, GIF, WebP, SVG, TXT — validated server-side by both file extension and detected MIME type.

Storage

Files stored on disk at {db_directory}/files/{uuid}{ext}, served via GET /api/files/{id}. The glyph's content field stores a JSON reference:

{ "fileId": "uuid", "filename": "original.pdf", "ext": ".pdf" }

Known limitations

Browser PDF toolbar: Browsers render their native PDF toolbar inside the <embed> element (page navigation, zoom, annotation controls). There is no cross-browser way to suppress it — Chrome's #toolbar=0 URL fragment is ignored by Firefox's pdf.js viewer. Replacing <embed> with pdf.js as a library would give full rendering control at the cost of a dependency and custom page navigation/zoom.
