How to draw image on bmp?

[thelastsummer]

I see functions to draw Arc, Circle, Line, Oval, Rect, but can not see function to draw bitmap. Is there any way to draw an existing image on bitmap?

[ChrisJohns-me]

I was able to accomplish this with something like:

(TypeScript)

const existingSrc = fromResource('existing_image');
const mutable = BitmapFactory.makeMutable(existingSrc);
let imgSrc;
BitmapFactory.asBitmap(mutable).dispose((bmp) => {
  imgSrc = bmp.toImageSource();
});

You can insert an image into the bitmap

(Javascript)

import {Folder, path, knownFolders} from "tns-core-modules/file-system";
import BitmapFactory from "nativescript-bitmap-factory"
import { ImageSource, fromFileOrResource, fromFile } from "image-source";

      const appFolder = knownFolders.currentApp();
      const logoPath = path.join(appFolder.path, "assets/images/ExistingLogoImage.png");
      const logoImgSource = fromFile(logoPath);

     var bmp = BitmapFactory.create(300, 300);
     bmp.dispose(function(b) {
        b.insert(logoImgSource, "25,25");
        const newImageSource = b.toImageSource();
        const saved = resizedImageSource.saveToFile(filePath, "jpeg", 50);
        if (saved) {
            console.log("Image saved successfully! Path:",filePath);
        }
      });
