So the next idea was, why not provide a compressed version of this format. The BDF format, needed to be compiled, for different architectures, and it was not compressed. This was simply an ASCII file, which defined the font, by using keys and values, as in:įONT -adobe-courier-bold-o-normal-10-100-75-75-m-60-iso10646-1 BDF, stands for bitmap distribution format. To start with, adobe came up with the BDF format. This being said, a natural question to ask, is, what are the font formats, supported by the server? So when designing, the idea was to minimize network bandwidth or transfer, as such some control was relinquished, to the entity responsible for handling the API calls, the server, hence the server was responsible for having the fonts, and creating bitmaps from characters. So the API calls, or the function calls, which are done by your program, called the client, are going to be done over a medium, the network. So, why the use of the term server and client, you might ask? Because when X11 was designed, it had in mind that communication will be done over a network. The server is responsible for converting characters, into bitmaps, using the fonts that it has installed. In X11 core font system, the server is responsible for having the fonts, so the fonts are stored, or installed on the server.
