// to modify how that method converts the document to .PDF.
PdfSaveOptions pdfSaveOptions = new PdfSaveOptions();

// Set the "ImageColorSpaceExportMode" property to "PdfImageColorSpaceExportMode.Auto" to get Aspose.Words to
// automatically select the color space for images in the document that it converts to PDF.
// In most cases, the color space will be RGB.
// Set the "ImageColorSpaceExportMode" property to "PdfImageColorSpaceExportMode.SimpleCmyk"
// to use the CMYK color space for all images in the saved PDF.
