This command, ifont, stands for 'install font', and will install a new font into your copy of geoSHELL. The font that is to be installed must naturally be a GEOS font, but there are some other rules that should also be followed. geoSHELL requires a non-proportional font in order to work properly. This means that every character must be the same width. Also, the width must be 7 pixels and a point size of 7 must be used. The baseline must be set at 5 pixels from the top of the character. Here's an example:
ifont CourierGS
This will take the 7-point font contained in the CourierGS font file and install it into the geoSHELL file that is on the currently active drive. The font need not be on the same drive.
To see the new font in action now, just enter 'run geoSHELL' and the geoSHELL file on the current drive will be loaded along with the new font that you just installed. If you like the looks of it, you can then copy this version of geoSHELL to your other workdisks, or just run the ifont command again on the other disks that contain geoSHELL.
By using the supplied font, CourierGS, as your starting point, you can use any available font editor and alter this font to suit your taste and then use ifont to install it. CourierGS is a nice looking font for 40 column mode. With a 128 in 80 column mode, it may not be a clear at you would like on some monitors. It will look good on a sharp monochrome monitor or a good-quality color monitor. If it does not suit you, just make a copy of the font and edit it with a font editor to fatten up portions of the characters for legibility.
Another good use for this command is to be able to use a font with different looking characters for use in foreign countries. Just edit the CourierGS font to suit your needs.
