Google Slides API Adding and Cropping Images

[Clay Smith]

I'm struggling to get the API to update the Offset of an image. It's returned that the ObjectID could not be found. When I use Google Apps Script. I've had a 200 response when using the API Explorer but didn't see any visual change. When I do the batch update creating the image and then updating it I get a 200 response but the image never displays.  What am I missing here?

var data = {requests=[{updateImageProperties={imageProperties={cropProperties={topOffset=0.2, bottomOffset=0.2, rightOffset=0.2, leftOffset=0.2, angle=0.0}}, fields=cropProperties.leftOffset, cropProperties.rightOffset, cropProperties.topOffset, cropProperties.bottomOffset, objectId=SLIDES_API372930775_0}}]}

var response = {

  "error": {

    "code": 400,

    "message": "Invalid requests[0].updateImageProperties: The object (SLIDES_API372930775_0) could not be found.",

    "status": "INVALID_ARGUMENT"

  }

}

Two different Code snippet methods below.

          
var p =  SlidesApp.getActivePresentation().getSlideById(slide_id).insertImage(url);

          var objID = p.getObjectId();

          var data = {"requests": [

            {"updateImageProperties": {

                "imageProperties": {

                  "cropProperties": {

                    "leftOffset": .2,

                    "rightOffset": .2,

                    "topOffset": .2,

                    "bottomOffset": .2,

                    "angle": 0

                  }

                },

               "fields": "cropProperties.leftOffset, cropProperties.rightOffset, cropProperties.topOffset, cropProperties.bottomOffset",

              "objectId": objID.toString(),

              }

            }

          ]};

          var options = {

            'headers':{'Authorization':'Bearer ' + ScriptApp.getOAuthToken()},

            'method' : 'post',

            'muteHttpExceptions': true,

            'contentType': 'application/json',

            'payload' : JSON.stringify(data) 

          };

          Logger.log(data);

          var response = UrlFetchApp.fetch('https://slides.googleapis.com/v1/presentations/'+ SlidesApp.getActivePresentation().getId() +':batchUpdate',options);

function addImage(presentationId, pageId, url, h, w, t, l) {

  var pageElementId = Utilities.getUuid();

  var requests = [{

    'createImage': {

      'objectId': pageElementId,

      'url': url,

      'elementProperties': {

        'pageObjectId': pageId,

        'size': {

          'width': {

            'magnitude': w,

            'unit': 'EMU'

          },

          'height': {

            'magnitude': h,

            'unit': 'EMU'

          }

        },

        'transform': {

          'scaleX': 1,

          'scaleY': 1,

          'translateX': l * 72 / 96,

          'translateY': t * 72 / 96,

          'unit': 'PT'

        }

      }

    }

  }, {

    "updateImageProperties": {

                "imageProperties": {

                  "cropProperties": {

                    "leftOffset": 0.5,

                    "rightOffset": 0.2,

                    "topOffset": 0.2,

                    "bottomOffset": 0.2,

                    "angle": 0

                  }

                },

               "fields": "cropProperties.leftOffset, cropProperties.rightOffset, cropProperties.topOffset, cropProperties.bottomOffset",

              "objectId": pageElementId

    }

  }];

  var response =Slides.Presentations.batchUpdate({'requests': requests}, presentationId);

  Logger.log('Created Image with ID: ' + response);

}

Out of my league here, but dumb question. In your addImage function, should the 'url' property be 'sourceUrl' instead? (Does that even matter?) That was the only thing I was able to see. (reference)

[Clay Smith]

I believe that is part of the GET request of an image. I'm working with the create image.  https://developers.google.com/slides/reference/rest/v1/presentations/request#CreateImageRequest But could certainly been the area of issue. I'll explore with some other urls.

And all I can actually come up with is that the crop properties are read-only. 

"The crop properties of the image. If not set, the image is not cropped. This property is read-only."

Please make a request here  https://issuetracker.google.com/issues/113978819 to have the cropping editable from the API.

Thanks
