Windows Metafile Format (WMF)
Developed by Microsoft Corporation, this file format stores both vector and bitmap information. It was developed as the file format for Microsoft Windows 3. It supports 24-bit RGB color and is supported by most Windows applications.
Windows Metafile Format (WMF) technical notes
• CorelDRAW substitutes fonts that are missing from a file in the WMF format from similar fonts available on your computer.
• A header contains additional information, such as sizing. Therefore, a WMF file can successfully be exported from CorelDRAW if the header is included.
• Text is maintained as text when exported, and WMF files can be very large. This can cause problems in programs that limit the size of imported files.
• The Windows Metafile Format is 16 bits, while CorelDRAW is 32 bits. When you export a WMF file, the 32-bit numbers are converted to 16 bits. For example, lines that are thinner than 0.01388 inch appear as hairlines because the WMF format does not have enough precision to specify these widths accurately.
