Using “bitmap checkpoint” we can compare the point to point positions of the expected and actual output images. This checkpoint works using the pixels of the image area or webpage area.

Whereas Image checkpoint checks only the properties related to the images like its source file, values etc.

For bitmap checkpoint we do not need a particular image, it checks the screen area whereas image checkpoint compulsorily needs an image. Using the bitmap checkpoint we can even test a part of an image.
