The Enhanced Metafile (EMF) file system began its journey of evolution when Microsoft included the Windows Metafile (WMF) format in the 1992 documentation of the Windows 3.1 Operating System. The WMF format was used to store collections of graphical drawing, the type peculiar with Windows positional graphics. However, due to some major compatibility issues, WMF was improved to EMF in the Windows NT 3.1 update. EMF formats stores coloured graphical data using the RGB colour scheme, CMYK is not supported. In recent times, the EMF format is incorporated into driver software for printers, thus assisting PCs to communicate graphical data to installed printers.

Unlike the 16-bit WMF format, EMF supports a wider device communication channel – 32-bit. Files with .emf extensions permit cross-compatibility between technologies that support positional graphics alone or bitmaps alone. EMF documents do not store data alone, but also include instructions on how constituent data should be handled.

PNG – is a scan-line graphic format developed as an alternative to GIF, a commercial license. However, they are both raster image types. PNG is based on the best features of the predecessor, including lossless compression and transparent background support. The PNG technology ensures the preservation of all stages of editing and the restoration of the step by preserving the quality. However, it does not allow us to save several pictures in one file at once, limiting its use in the development of animated images.

The PNG extension was proposed as a tool that helps to transfer and store images on the World Wide Web. The technology is limited to an 8-bit transparency channel so that you can adjust the colors from opaque to transparent. It supports 24-bit RGB colors, matching images, and shades of gray. However, as a non-professional format, PNG can not display other color spaces. Most programs allow you to open such files. They can also run in any browser. Images are different in small weight with good quality.
