Convert pgm to uil

What is the difference between .pgm and .uil?

Description: A PGM file is a grayscale image file saved in the portable gray map (PGM) format and encoded with one or two bytes (8 or 16 bits) per pixel. It contains header information and a grid of numbers that represent different shades of gray from black (0) to white (up to 65,536). PGM files are typically stored in ASCII text format, but also have a binary representation.; X-Motif UIL Table (UIL) is a plain text file format used by the User Interface Language (UIL) compiler, which is used for creating user interfaces for the X Window System. This format is used for defining menus, buttons, dialog boxes, and other components of graphical user interfaces. UIL files are written using a set of keywords and parameters that can be used to set up the visual elements of the user interface.
