- 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.
- A PPM file is a 24-bit color image formatted using a text format. It stores each pixel with a number from 0 to 65536, which specifies the color of the pixel. PPM files also store the image height and width, whitespace data, and the maximum color value.
