- Description
- A Printer Font Metrics (PFM) file is a type of file associated with Adobe Type 1 fonts used in Microsoft Windows. It contains metric information about a font, such as character widths, heights, and kerning pairs, which are essential for correctly displaying and printing text. The PFM file works in conjunction with a PFB (Printer Font Binary) file, which contains the actual font outline data.
- This format is used to compress TIFF images when sending them via fax machines. This format helps reduce the data transmission time. Group 3 eliminates redundant data during compression in order to reduce file size. The standard 10:1 compression ratio may be increased to the user's preferences, but it can lead to a significant loss of image quality.
