How do you increase the resolution of a image screenshot?

The resolution of an image is determined by the number of pixels it contains. Therefore to increase the resolution you need to increase the dimensions of the screensho by passing larger values to the setHeight and setWidth methods. Just ensure the browser height and width are larger than the width and height you are specifying!

Alternatively if you want to improve the quality of a image you can change the format and quality parameters.
