insert image at specific point of paragraph - google-apps-script

Question

*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?

Answer 1

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);
}

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.

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();
}
