1. Introduction

This HTML page showcases an interactive map integrated using the Google Maps JavaScript API. The page allows users to place a marker on the map, capture a screenshot of the map, and save it as a PNG image.

2. HTML Structure

Head Section

In the head section, we include necessary metadata, styles, Google Maps API, and the HTML2Canvas library for capturing a screenshot.

Body Section

In the body section, we have a map container, an input to search for a location, and a button to capture and save the screenshot.

3. Google Maps Integration

The initMap function initializes the Google Map, sets the default center and zoom level, and sets up a click event listener to place a marker on the map when clicked.

4. Screenshot Capture and Download Logic

The "Capture and Save Screenshot" button triggers a function to capture the screenshot of the map container using HTML2Canvas. Once the screenshot is captured, it is converted to a Blob and saved as a PNG image. The logic creates a temporary link element (<a>) to trigger the download, specifying the desired filename for the downloaded image, and triggering a click event on the link to initiate the download.

This logic ensures that users can capture a screenshot of the map and download it as "map_screenshot.png" by clicking the designated button.

5. Conclusion

This HTML page provides a simple and interactive way to capture and save a screenshot of the map. Users can utilize and integrate this functionality into their projects for map screenshot features.
