<itemvalue="PNG format. A loss-less compression format for images. This format is well suited for images with hard edges, such as screenshots or sprites, and images with text. Transparency is supported. The PNG format supports images up to 2,147,483,647 pixels in either dimension, though in practice available memory provides a more immediate limitation on maximum image size. PNG images normally use the `.png` file extension and the `imagepng` MIME type. See also: <https:en.wikipedia.orgwikiPortable_Network_Graphics>, the Wikipedia page on PNG. <https:tools.ietf.orgrfcrfc2083.txt>, the PNG standard."/>
