Google Script Replace Image in gDraw File

Question

So I am trying to write a Google script that will create an image file from 3 different image files that are on google drive. The method that I have decided to use was to create a template or a base gDraw file in Drive and then modify the file and export it as a jpeg. So far I've been able to export my gDraw file as image using the code from this post 1)Is there a Google Appscript command that can convert a .gDraw to a .jpg? 2)Can a trigger be set to perform this conversion on .gdraw file edit? .

function gDrawTO_jpeg(){
  var gDrawFile = Drive.Files.get('1P2qYTyeI9RovsI_qwiMEtlBeTJw-exjckQeYLL_NA7w'); 
  var url = gDrawFile.exportLinks['image/jpeg'];
  var token = ScriptApp.getOAuthToken();
  var response = UrlFetchApp.fetch(url, {
      headers: {
                'Authorization': 'Bearer ' +  token
               }
   });
  var jpeg = response.getBlob();
  // save drawing as jpeg file to Drive, or do whatever you need to with the blob
  DriveApp.createFile(jpeg);
}

What I'm stuck on is trying to figure out how to replace the images in the gDraw file.

Thanks in advance for any help!

I've never come across API for Google Draw, which mean is wouldn't contactable by script for editing. However, just a month ago Google came out with the Slide API which you can remotely add images to. Don't know if this helps, the slide could then be embedded.

Thanks for the direction. Here is where I've gotten by adapting some different code I have found. I currently have a slide with one image that never changes and 2 shapes that represent where the other 2 images go. I build a new copy of the slide and then call downloadPresentation(id)from this post How to download Google Slides as images? to export the new slide as a PNG!

function slides_template() {


  var IMG_FILE = 'IMG_4096.JPG'      
  var TMPLFILE = 'Grid Template' 
  var SZIMG_FILE = 'onesize.jpeg'  


  SLIDES.setTokenService(function(){returnScriptApp.getOAuthToken()});


  Logger.log('** Copying template **');
  var DECK_ID = DriveApp.getFilesByName(TMPLFILE).next().makeCopy().getId();


  Logger.log('** Searching for files');
  var rsp = DriveApp.getFilesByName(IMG_FILE).next();
  var szrsp = DriveApp.getFilesByName(SZIMG_FILE).next();

  Logger.log(Utilities.formatString(' - Found image %s', rsp.getId()));

  var img_url = rsp.getDownloadUrl()+"&access_token="+ScriptApp.getOAuthToken();
  var szimg_url = szrsp.getDownloadUrl()+"&access_token="+ScriptApp.getOAuthToken();


  Logger.log('Inserting Images');
var reqs = [    

  {"replaceAllShapesWithImage": {

  "imageUrl": img_url,
  "replaceMethod": "CENTER_CROP",
  "containsText": {
           "text": "Main_Image",
           "matchCase": "True",
               }
  },},

    {"replaceAllShapesWithImage": {

  "imageUrl": szimg_url,
  "replaceMethod": "CENTER_CROP",
  "containsText": {
           "text": "Size_Image",
           "matchCase": "True",
               }
  },},

  ];


  SLIDES.presentationsBatchUpdate(DECK_ID, {'requests': reqs});

  downloadPresentation(DECK_ID)

  Logger.log('DONE'); 
}
