@akwatra can you give a code snippet or demo project that demonstrates your case?

[akwatra]

I guess you can test with "tns-core-modules/image-source"
its reference from there

  saveImage(imageAsset){

    const img = imageSourceModule.fromFile(imageAsset._android);
    const folderDest = fileSystemModule.knownFolders.documents();
    const pathDest = fileSystemModule.path.join(folderDest.path, "app/images/" + "_test.png");

    const saved = img.saveToFile(pathDest, "png");
    if (saved) {
        console.log("Image saved successfully!");
         that.imgBill = pathDest;
    }          

 }

@akwatra the thing is that the new fromFileSync is a static method of ImageSource class. So that said you need to call it via the ImageSource class itself.

Here is a TypeScript example to make things more clear

import { fromFile, ImageSource } from "tns-core-modules/image-source";

const imgWithDeprecatedMethod = fromFile(path);
const img = ImageSource.fromFileSync(path);

And the same in plain JavaScript

let fromFile = require("tns-core-modules/image-source").fromFile; // deprecated method
let ImageSource = require("tns-core-modules/image-source").ImageSource;

let imgWithDeprecatedMethod = fromFile(path);
let img = ImageSource.fromFileSync(path);
