## WarningInfo class

Contains information about a warning that Aspose.Words issued during document loading or saving.
To learn more, visit the [Programming with Documents](https://docs.aspose.com/words/python-net/programming-with-documents/) documentation article.




### Remarks

You do not create instances of this class. Objects of this class are created
and passed by Aspose.Words to the [IWarningCallback.warning()](../iwarningcallback/warning/#warninginfo) method.




### Properties

| Name | Description |
| --- | --- |
| [description](./description/) | Returns the description of the warning. |
| [source](./source/) | Returns the source of the warning. |
| [warning_type](./warning_type/) | Returns the type of the warning. |

### Examples

Shows how to set the property for finding the closest match for a missing font from the available font sources.

```python
# Open a document that contains text formatted with a font that does not exist in any of our font sources.
doc = aw.Document(file_name=MY_DIR + 'Missing font.docx')
# Assign a callback for handling font substitution warnings.
warning_collector = aw.WarningInfoCollection()
doc.warning_callback = warning_collector
# Set a default font name and enable font substitution.
font_settings = aw.fonts.FontSettings()
font_settings.substitution_settings.default_font_substitution.default_font_name = 'Arial'
font_settings.substitution_settings.font_info_substitution.enabled = True
# Original font metrics should be used after font substitution.
doc.layout_options.keep_original_font_metrics = True
# We will get a font substitution warning if we save a document with a missing font.
doc.font_settings = font_settings
doc.save(file_name=ARTIFACTS_DIR + 'FontSettings.EnableFontSubstitution.pdf')
for info in warning_collector:
    if info.warning_type == aw.WarningType.FONT_SUBSTITUTION:
        print(info.description)
```
