How to Set Typeface of Fonts of Major/Minor of Font Scheme of Master Theme?

Aspose.Slides Product Family

In theme1.xml of unzipped pptx, there are global font settings like below.

<a:font script="Jpan" typeface="XXX" />
<a:font script="Hang" typeface="XXX" />
<a:font script="Hans" typeface="XXX" />

I checked presentation.master_theme.font_scheme.major, there is no methods to get global font settings.

How can we change the typeface value with Aspose.Slides?

thanks

To change the typeface of the fonts in the major and minor font schemes of a master theme using Aspose.Slides, you can utilize the font_scheme property of the master_theme. Here’s how you can set the typeface for both major and minor fonts:

from aspose.slides import Presentation, FontData

# Load your presentation
presentation = Presentation("your_presentation.pptx")

# Access the master theme
master_theme = presentation.master_theme

# Set the typeface for the major font scheme
master_theme.font_scheme.major.latin_font = FontData("Your Major Font")

# Set the typeface for the minor font scheme
master_theme.font_scheme.minor.latin_font = FontData("Your Minor Font")

# Save the presentation
presentation.save("updated_presentation.pptx")

In this code snippet:

  • Replace "Your Major Font" and "Your Minor Font" with the desired font names.
  • The latin_font property is used to specify the font for the Latin script. You can also set fonts for other scripts if needed.

Keep in mind that the font set for the master theme will only apply if no specific font is set for the text in the slides. If you have set a different font for a text element, the master theme font will not override it.

For more detailed information, you can refer to the documentation on Presentation Theme and Text Formatting.

If you encounter any issues or need further assistance, feel free to ask!

That code does not change special language fonts but change following three items.

        <a:fontScheme name="Century Schoolbook">
            <a:majorFont>
                <a:latin typeface="XXX" />
                <a:ea typeface="XXX" />
                <a:cs typeface="XXX" />

I want to change special language font names.

        <a:fontScheme name="Century Schoolbook">
            <a:majorFont>

                <!-- I know we can change these three fonts -->
                <a:latin typeface="XXX" />
                <a:ea typeface="XXX" />
                <a:cs typeface="XXX" />

                <!-- I want to change special language font names -->
                <a:font script="Jpan" typeface="XXX" />
                <a:font script="Hang" typeface="XXX" />
                <a:font script="Hans" typeface="XXX" />
                . . .
