What is the relevance of DPI in the BitmapSource.Create () method?

I read the Wikipedia article on DPI , but it confused me even more ... I have no DPI information on the image, Which DPI should I use with BitmapSource.Create () , is it possible to use a constant (96/72?), And really Does it matter if I do not print the image?

DPI does not affect the pixels of the bitmap image. DPI images are simply attached metadata, which is a dimension used to describe how large in real dimensions every pixel should be.
