Fitting the image to the screen
It is important that your screen is of sufficient height and width to display images at
all the aspect ratios you are planning to use.
Use the conversion chart, or the sample calculations below to check that you are
able to display the full image on your screen. If you have insufficient height or width,
you will have to reduce the overall image size in order to display the full image on
your screen.
