Unable to capture 'screenshot' of Google map

roguebug commented 3 years ago

First of all, great work. This is the easiest to use and WORKING module.

I tried to save Google map as an image. The generated image is not exactly the same. In some case, it is very different.

Expected Behavior

The image should look the same as the google map

Current Behavior

See attached screenshots. The left is a Google map using agm-map. The right is generated data PNG. In picture 1, the generated image is very different. In picture 2, only part of the Google map is in the PNG.

html-to-image-googlemap - 1 html-to-image-googlemap - 2

My code is nothing fancy: htmlToImage.toPng(element).then((dataUrl) => { that.imageData = dataUrl; }).catch(function (error) { console.error('oops, something went wrong!', error); });

I noticed the error message in the console: Error while reading CSS rules from https://fonts.googleapis.com/css?family=Roboto:300,400,500,700|Google+Sans:400,500,700 SecurityError: Failed to read the 'cssRules' property from 'CSSStyleSheet': Cannot access rules

Not sure if this is what screws up the image rendering.

I managed to solve this issue with the html2canvas library. Adding the { useCORS: true } option made it magically it work for me.

If anyone needs, I'm sharing my custom React hook below:

import html2canvas from 'html2canvas';
import { MutableRefObject } from 'react';

/**
 * A hook that exports a function allowing to capture a specific HTMLElement as an image.
 */
export function useScreenshot<T extends HTMLElement>(ref: MutableRefObject<T | null>, filename: string) {
  const takeScreenShot = async (node: T | null) => {
    if (!node) {
      return;
    }

    const dataURI = await html2canvas(
      node,
      // This is a very important line as it allows to capture an image of Google Maps!
      { useCORS: true },
    );
    return dataURI;
  };

  const download = (canvas?: HTMLCanvasElement) => {
    const a = document.createElement('a');

    a.target = '_blank';
    a.href = canvas?.toDataURL() ?? '';
    a.download = `${filename}.jpeg`;
    a.click();
  };

  const downloadScreenshot = () => takeScreenShot(ref.current).then(download);

  return { downloadScreenshot };
}
