    Load Presentation document with options

    GroupDocs.Conversion provides PresentationLoadOptions to give you control over how the source presentation document will be processed. The following options could be set:

    • setFormat allows you to specify explicitly the type of the source presentation document. Available options are: Ppt, Pps, Pptx, Ppsx, Odp, Otp, Potx, Pot, Potm, Pptm, Ppsm.
    • setDefaultFont sets a default font for rendering the presentation. The following font will be used if a presentation font is missing.
    • setFontSubstitutes sets substitute specific fonts from the source presentation document.
    • setPassword specifies a password to unlock the protected document.
    • setHideComments specifies that comments from source presentation must be hidden during conversion.
    • setShowHiddenSlides specifies that hidden slides should be included in the converted document.

    Hide comments

    The following code snippet shows how to convert a presentation and hide comments:

    const loadOptions = new groupdocs.conversion.PresentationLoadOptions()
loadOptions.setHideComments(true)

const outputPath = "ConvertPresentationByHidingComments.pdf"

const converter = new groupdocs.conversion.Converter("sample.pptx", loadOptions)
const convertOptions = new groupdocs.conversion.PdfConvertOptions()

console.log(`Pdf document converted successfully to ${outputPath} (by hiding comments)`)
converter.convert(outputPath, convertOptions)

    Specify font substitutions

    The following code snippet shows how to convert a presentation and specify font substitutions for missing fonts:

    const java = require('java') 

const outputPath = "ConvertPresentationBySpecifyingFontSubstitution.pdf";

const fontSubstitutes = java.newInstanceSync("java.util.ArrayList");
fontSubstitutes.add(groupdocs.conversion.FontSubstitute.create("Tahoma", "Arial"));
fontSubstitutes.add(groupdocs.conversion.FontSubstitute.create("Times New Roman", "Arial"));

const loadOptions = new groupdocs.conversion.PresentationLoadOptions()
loadOptions.setDefaultFont("Helvetica.ttf");
loadOptions.setFontSubstitutes(fontSubstitutes);

const converter = new groupdocs.conversion.Converter("sample.pptx", loadOptions);
const convertOptions = new groupdocs.conversion.PdfConvertOptions();

console.log(`Pdf document converted successfully to ${outputPath} (by specifying font subs)`);
converter.convert(outputPath, convertOptions);

    Include hidden slides

    The following code snippet shows how to convert a presentation including the hidden slides:

    const loadOptions = new groupdocs.conversion.PresentationLoadOptions()
loadOptions.setShowHiddenSlides(true)

const outputPath = "ConvertPresentationWithHiddenSlidesIncluded.pdf"

const converter = new groupdocs.conversion.Converter("sample.pptx", loadOptions)
const convertOptions = new groupdocs.conversion.PdfConvertOptions()

console.log(`Pdf document converted successfully to ${outputPath} (with hidden slides included)`)
converter.convert(outputPath, convertOptions)
