insert image at specific point of paragraph

问题:

*I have a Google Document with a string like "text {logo} text" How do place an image where {logo} is? So far I tried:

var logoElement = s.findText("{logo}").getElement();
logoElement.getParent().insertInlineImage(0,logoBlob);
s.replaceText("{logo}", "");

But this inserts the image before the found paragraph (or with 1: after). How do I place it inside the paragraph at the exact location?

I hope will be helpful, The following code is fine to me.

function insertImage(doc) {
  // Retrieve an image from the web.
  var resp = UrlFetchApp.fetch("http://www.google.com/intl/en_com/images/srpr/logo2w.png");
  var image = resp.getBlob();
  var body = doc.getBody();
  var oImg = body.findText("<<Logo1>>").getElement().getParent().asParagraph();
  oImg.clear();
  oImg = oImg.appendInlineImage(image);
  oImg.setWidth(100);
  oImg.setHeight(100);
}

I tried a simpler version based on your answer that keeps the format of the original paragraph...

Give it a try, it's not "foolproof" but it works in my test and is (I think) an interresting trial ;-)

code here :

function test(){
  placeImage('{logo}','0B3qSFd3iikE3SkFXc3BYQmlZY1U');
//This is my page and I’d like to have a {logo} on it right here
}


function placeImage(placeHolder,imageId) {
  var logoBlob = DocsList.getFileById(imageId).getBlob();
  var d = DocumentApp.getActiveDocument()
  var s = d.getHeader();
  var logoResult = s.findText(placeHolder); 
  var placeholderStart = logoResult.getStartOffset(); 
  var par = s.getChild(0).asParagraph();
  var parcopy = par.copy();
  var parLen = par.editAsText().getText().length-1;
  Logger.log('placeholderStart = '+placeholderStart+'  parLen = '+parLen)
  par.editAsText().deleteText(placeholderStart, parLen);
  parcopy.editAsText().deleteText(0, placeholderStart+placeHolder.length);
  var img = s.getChild(0).appendInlineImage(logoBlob);
  s.appendParagraph(parcopy);
  parcopy.merge();
}

Thanks to the comment from Serge and the original post of the link for pointing me in the right direction. Here's what I have now:

var s = d.getHeader();
var logoResult = s.findText("{logo}"); // search result
var logoElement = logoResult.getElement(); // the paragraph that contains the placeholder
var text = logoElement.getText();
var placeholderStart = logoResult.getStartOffset(); // character position start placeholder
var placeholderEnd = logoResult.getEndOffsetInclusive(); // char. position end placeholder
var parent = logoElement.getParent(); 
var parPosition = parent.getChildIndex(logoElement);

// add new paragraph after the found paragraph, with text preceding the placeholder
var beforeAndLogo = s.insertParagraph(parPosition+2, text.substring(0, placeholderStart));
var logo = beforeAndLogo.appendInlineImage(logoBlob); // append the logo to that new paragraph

// add new paragraph after the new logo paragraph, containing the text after the placeholder
var afterLogo = s.insertParagraph(parPosition+3, text.substring(placeholderEnd+1));
afterLogo.merge(); // merge these two paragraphs

// finally remove the original paragraph
parent.removeFromParent(); // remove the original paragraph

It is not complete, I should also copy all the attributes. More importantly, it does not copy the tab settings (e.g. center tab). Have not found a way to set tab positions.
