Change Fonts in an Existing PowerPoint Document in Python
To change the font for a specific paragraph, we need to get the paragraph from the document. Then, iterate through the text ranges in the paragraph and reset the font information for each text range. Below are the steps to change the font of a paragraph in an existing PowerPoint document using Spire.Presentation for Python.
- Create a Presentation object.
- Get a specific slide through Presentation.Slides[index] property.
- Get a specific shape through ISlide.Shapes[index] property.
- Get a specific paragraph of the shape through IAutoShape.TextFrame.Paragraphs[index] property.
- Iterate through the text ranges in the paragraph.
- Set the font information such as font name, font size, bold, italic, underline, and text color of a specific text range through the properties under the TextRange object.
- Save the presentation to a PPTX file using Presentation.SaveToFile() method.
