Answer 1

this code I wrote a while ago does the job if the attachement is in a format that can be converted to pdf. It gets the message in the last thread and sends both body and attachment only if an attachment is present. This is a test script.

function getAttachAndBody(){
  var firstThread = GmailApp.getInboxThreads(0,1)[0];
  var message = firstThread.getMessages()[0];
  var attach = message.getAttachments();
  var body = message.getBody();//is a string
  var bodydochtml = DocsList.createFile('body.html', body, "text/html")
  var bodyId=bodydochtml.getId()
  var bodydocpdf = bodydochtml.getAs('application/pdf').getBytes();
  if(attach.length>0){
    var file=DocsList.createFile(attach[0])
    var pdf=file.getAs('application/pdf').getBytes();
    var attach_to_send = {fileName: 'pdftest.pdf',content:pdf, mimeType:'application/pdf'};
    var body_to_send = {fileName: 'body.pdf',content:bodydocpdf, mimeType:'application/pdf'};
//    MailApp.sendEmail('xxxxxxx@gmail.com', 'transfer email as pdf : body ', 'see attachment', {attachments:[body_to_send]});
    MailApp.sendEmail('xxxxxxx@gmail.com', 'transfer email as pdf : body & attachment', 'see attachment', {attachments:[attach_to_send,body_to_send]});
    file.setTrashed(true);
    DocsList.getFileById(bodyId).setTrashed(true)
    }
}
