How To Change Font Size With The Python-Pptx Library Mới Update

To change the font size in a PowerPoint slide using the python-pptx library, you can follow these steps:

1. Import the necessary modules:

   python
   from pptx import Presentation
   from pptx.util import Pt
   

2. Load the PowerPoint presentation file:

   python
   prs = Presentation('your_presentation.pptx')
   

3. Access the slide that you want to modify:

   python
   slide = prs.slides[0]  # Access the first slide in the presentation
   

4. Access the text box containing the text that you want to modify:

   python
   text_box = slide.shapes[0].text_frame  # Access the first text box on the slide
   

5. Set the font size of the text using the font.size attribute and the Pt() function to convert the font size to PowerPoint points:

   python
   text_box.paragraphs[0].font.size = Pt(24)  # Set the font size to 24 points
   

6. Save the modified presentation file:

   python
   prs.save('modified_presentation.pptx')
   

Here’s an example code snippet that changes the font size of the first text box on the first slide of a PowerPoint presentation to 24 points:

python
from pptx import Presentation
from pptx.util import Pt

# Load the PowerPoint presentation file
prs = Presentation('your_presentation.pptx')

# Access the first slide in the presentation
slide = prs.slides[0]

# Access the first text box on the slide
text_box = slide.shapes[0].text_frame

# Set the font size to 24 points
text_box.paragraphs[0].font.size = Pt(24)

# Save the modified presentation file
prs.save('modified_presentation.pptx')
