Editor editor = new Editor("source.pptm", new PresentationLoadOptions());

// Create and adjust the edit options
PresentationEditOptions editOptions = new PresentationEditOptions();
editOptions.setSlideNumber(1);//select a slide to edit

// Open input PPTM document for edit — obtain an intermediate document, that can be edited
EditableDocument beforeEdit = editor.edit(editOptions);

// Grab PPTM document content and associated resources from editable document
string content = beforeEdit.getEmbeddedHtml();

// Send the content to WYSIWYG-editor, edit it there, and send edited content back to the server-side
// This step simulates a such operation
string updatedContent = content.replace("Title", "Edited Title");

// Grab edited content and resources from WYSIWYG-editor and create a new EditableDocument instance from it
EditableDocument afterEdit = EditableDocument.fromMarkup(updatedContent, null);

PresentationSaveOptions saveOptions = new PresentationSaveOptions(PresentationFormats.Pptm);
