Change the canvas background color using html2canvas

Currently, I am utilizing html2canvas to capture screenshots of specific elements within a webpage.

html2canvas(element).then(canvas => canvas.toDataURL());

Everything works perfectly fine, except for one issue - the background color of the page is not being captured. Is there a solution within html2canvas to address this problem, or perhaps a way to manually set a background color?

Answer №1

To easily change the background color of an element for a snapshot and then revert it back, follow these steps:

const targetElement = document.getElementById('your-element-id');

// Adjust background color for snapshot
targetElement.style.backgroundColor = '#ffffff';  // Change to desired color

// Capture element with html2canvas
html2canvas(targetElement).then(canvas => {
    // Restore background color after capturing
    targetElement.style.backgroundColor = 'transparent';  // Set back to default or your choice

    // Utilize the canvas as needed
    const imageURL = canvas.toDataURL();
    console.log(imageURL);
});
