### Examples

Shows how to use a byte array with data from a font file as a font source.

```python
font_bytes = system_helper.io.File.read_all_bytes(MY_DIR + 'Alte DIN 1451 Mittelschrift.ttf')
memory_font_source = aw.fonts.MemoryFontSource(font_data=font_bytes, priority=0)
doc = aw.Document()
doc.font_settings = aw.fonts.FontSettings()
doc.font_settings.set_fonts_sources(sources=[memory_font_source])
self.assertEqual(aw.fonts.FontSourceType.MEMORY_FONT, memory_font_source.type)
self.assertEqual(0, memory_font_source.priority)
```
