FontSubstitutionContext class Leave feedback
On this page
Describes a single font substitution that occurred while loading or rendering a source document.
Instances are passed to ConversionEvents.on_font_substituted.
The FontSubstitutionContext type exposes the following members:
| Constructor | Description |
|---|---|
| init | Initializes a new FontSubstitutionContext. |
| Property | Description |
|---|---|
| original_font_name | The name of the font referenced by the source document but unavailable to the conversion pipeline. |
| reason | The substitution message exactly as reported by the conversion pipeline, verbatim and unparsed. |
| source_file_name | The file name of the source document being converted. When the source was provided as a stream that is not a io.RawIOBase, this contains a generated identifier rather than a real file name. |
| substitute_font_name | The name of the font used as a substitute. May be None for documents whose engine reports the substitution only as descriptive text — in that case read FontSubstitutionContext.reason. |
